CS259637B1 - Dispenser container end valve - Google Patents

Abstract

The solution concerns the elimination of fluid losses in the dosing containers, which are part of continuous dough makers, using an end valve. When the fluid dose was interrupted, the fluid leaked into the waste for the duration of the interruption. The end valve is controlled by a nylon line with an electromagnet, which is connected to the lower flour dosing vibrator. When the flour dosing is turned off, the end valve immediately closes the fluid and when turned on, it releases the fluid again. The end valve with the diaphragm is placed in the hub in the bottom of the dosing container and secured with a nut. Above the diaphragm is a valve seat, into which a rubber cone fits. This is controlled via a pin with a nylon line passing through the guide eye to the electromagnet. The rubber cone opens and closes the fluid supply to the diaphragm, which automates its dosing during intermittent dough production and achieves maximum savings in raw materials.

Description

The invention relates to the removal of fluid losses on dispensing containers by means of an end valve.

In the production of dough on continuous dough manufacturers (hereinafter referred to as KVT) there is a short-term but frequent interruption of production, whether for technological, technical, capacity or production reasons.

Calibration vessels are used to dispense fluids on these KVTs to ensure a constant flow. In the original embodiment, the dispensing container was controlled by the solenoid valve. When the dough production was interrupted, this valve closed the inlet to the container and the liquid from the pipe and container was discharged to waste. Since the solenoid valve was inoperative due to the aggressiveness of the solutions, there was no leakage of the fluid until the next production of the CHP. Restarting the continuous dose required a break of 3-4 min. to stabilize the level in the dosing reservoir (because of impurities and air bubbles).

Figure 1 shows a complete dispenser with an end valve and level control.

Figure 2 is a detail of the orifice valve.

The solution of the invention consists in the immediate closure of the fluid by an end valve at the lowest point of the container located above the calibration orifice.

Giant. 1. This valve is controlled by means of a nylon line 3 by an electromagnet 2, which is connected to the bottom vibrator of the flour dosing. The float valve 5 maintains a constant level in the dosing container 4. Level control is performed by screw 8. When the flour dosing is turned off, the end valve 7 immediately closes the fluid and the float valve 5 then closes the supply line 1. thereby eliminating further manipulation and adjustment of the dispensing container 4.

Giant. 2 - description of the end valve.

Above the orifice 13 there is a valve seat 15 into which the rubber plug 12 fits. This is actuated via the pin 11 and the nylon line 3 passing through the guide eye 9 through the electromagnet 2. The orifice valve 13 is located in the hub 17 nut 16.

The advantage of the new solution is almost 100% elimination of fluid losses, simplification of operator work and automation of fluid dosing.

With minimal valve labor and low production costs (approx. CZK 200), relatively large savings in raw materials were achieved.

The particular application has been tried to dispense salt solution in a continuous dough maker. Furthermore, the valve can be used in the same equipment for dosing of sugar solution, tempered water, yeast solution etc. It is also possible to use the valve in other fields wherever constant liquid dosing is to be ensured with minimal losses during short-term intermittent operation. When used on thicker fluids (eg oil) it is possible to increase the cone pressure by inserting a stainless steel spring between the rubber cone 12 and the guide eye 9.
