Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a solid-liquid separator that separates livestock manure into liquid and solid components.

Prior Art As shown in FIG. 2, a conventional solid-liquid separator has numerous small holes supported from the inside by rollers 3a, 3b, and 3c pivotally connected to a frame 1 via shafts 2a, 2b, and 2c. A roller 5 for squeezing is rolled into contact with the screen drum 4 on the outer periphery of the screen drum 4, and a solid material having a width approximately the same as the width of the roller 5 is placed at a position below the roller 5. There is one in which a chute 6 for separating objects is attached so as to be in line contact with the screen drum 4. Note that 7 is a hopper for supplying livestock manure, 8 is a drive device for forcibly driving the rollers 2a and 5 via a belt and gears, and 9 and 10 are chute for collecting liquid. It is. Also 11
are reinforcing rings attached to the circumference of both ends of the screen drum 4.

In the above configuration, the slaughtered manure supplied from the hopper 7 is conveyed to the pressing roller 5 as the screen drum 4 rotates. The livestock manure is pressed against the screen drum 4 by the pressing roller 5, and the liquid is collected through small holes provided in the screen drum 4 into chutes 9 and 10 for liquid collection. Further, the pressed livestock dung is filtered and separated as dried livestock dung in the chute 6.

Problems to be Solved by the Invention However, in such a conventional device, the squeezing roller 5 is not configured to roll into contact with the entire outer surface of the screen drum 4 because the reinforcing ring 11 itself is distorted. For that reason,
Liquid is washed away and adheres to both ends of the screen drum 4 and the reinforcing ring 11 during squeezing.As the screen drum 4 rotates, this adhered liquid mixes with livestock manure supplied from the hopper 7 and becomes water. I had some inconveniences when I got fat.

Therefore, in view of the drawbacks of the conventional technology, the present invention
The purpose is to eliminate liquid that adheres to the screen drum and reinforcing ring.

Means for Solving the Problem In a solid-liquid separator for livestock manure, in which the liquid content of livestock manure is separated by a screen drum, and the solid content is separated by bringing a silite into line contact with the screen drum. This objective is achieved by a solid-liquid separator for animal manure, which has a scraper for scraping off liquid that is brought into pressure contact with a reinforcing ring fixed on the circumference of both ends of the animal manure.

Function In the device according to the present invention, when livestock manure is supplied from the hopper to the screen drum, the livestock manure is conveyed toward the squeezing roller by the rotation of the screen drum. There, the liquid and solid components are separated, but since the squeezing rollers at both ends of the screen drum do not roll,
Liquid adheres to the small holes of the screen drum and the reinforcing ring.

However, since this adhered liquid is scraped off by the scraper provided in the device according to the present invention, the liquid adhered to the screen drum etc. does not rotate to the hopper for supplying livestock manure. Due to errors that occur when creating the screen drum, the screen drum is not a perfect circle and has distortions, and the reinforcing ring that reinforces the screen drum also becomes distorted when welded to the screen drum. Therefore, as the screen drum rotates, the screen drum and reinforcing ring move slightly. However, since the scraper of the device according to the present invention is configured to be in pressure contact with the reinforcing ring and the screen drum, it constantly responds to changes in the positions of the screen drum and the reinforcing ring, thereby removing the liquid that adheres to the screen drum and the reinforcing ring. You can scrape off the portion.

Embodiments The present invention will be described in detail below with reference to embodiments shown in the drawings.

In FIG. 1, 20 is a screen drum having numerous small holes;
A reinforcing ring 21 is fixed on the circumference of both ends for reinforcement. Reference numeral 22 denotes a frame of the device according to the present invention, and a scraper is inserted between a hopper (not shown) for supplying livestock manure provided on this frame 22 and a chute (not shown) for storing liquid through a bracket 25. The means 26 is the screen drum 20
It is attached so that it makes sliding contact with both ends of the outer surface of the. This scraper means 26 includes a scraping part 27 made of synthetic resin arranged so that one surface is in contact with the screen drum 20 and the other surface is in contact with the reinforcing ring 21, and a part of the scraping part 27. support plates 28a and 28b fixed to the bracket 25 which is slidably fitted thereto, stoppers 29a and 29b fixed to the scraping part 27 and the support plate 28a, and a pressure spring passed between the stoppers 29a and 29b. Consists of 30. This pressure spring 30
Due to the pressure action of
Both the screen drum 1 and the screen drum 20 are pressed against each other.

Therefore, the reinforcing ring 21 or the screen drum 2
Even if any position of 0 is shifted, no gap will be created between the scraping part 27 and the scraping part 27.

In addition, in the device according to the present invention, the scraper is configured to be in pressure contact with both the screen drum and the reinforcing ring, but the angle at which the pressure spring pushes out the scraping part is different from the screen drum.
The angle is preferably about 45°.

Effects As described above, in the solid-liquid separator for animal manure according to the present invention, since the scraper means removes the liquid adhering to the screen drum and the reinforcing ring, it is difficult to separate the solids from the liquid. Even if liquid adheres to the end of the screen drum and the reinforcing ring later, it is scraped off, so that when the livestock manure is supplied from the livestock manure supply hopper, no liquid is mixed into the livestock manure. Therefore, solid matter and liquid can be separated more completely.
