[0019] Referring to Figure 1 , Figure 1 A novel thick thickener feed square box structure schematic diagram in an embodiment of the utility model is shown, the device includes feed pipe 1, box 2, blanking pipe one 3, block screen 4, blanking pipe two 5 and low pressure steam pipe 6. Block screen 4 adopts large inclination angle design, is fixedly inclined in box 2, and divides box 2 into two regions of blanking area and block area, after the removal liquid in feed pipe 1 is filtered through block screen 4, filtrate falls into blanking area;The block material in the removal liquid is intercepted by block screen 4, and slides into the block area along the inclination slope of the screen. Blanking pipe one 3 is connected with the blanking area of the box 2, blanking pipe two 5 is connected with the block area of the box 2, and low pressure steam pipe 6 is connected with the block area of the box 2.
[0020] The tank 2 is provided with a liquid level gauge 7, and the feeding pipe 1 is provided with a pneumatic valve 8, which is interlocked with the liquid level gauge 7, and is set with an upper limit liquid level, and is electrically connected with an alarm, when the liquid level in the tank 2 rises to the upper limit liquid level, the pneumatic valve 8 is automatically closed, the feeding pipe 1 stops feeding, and the alarm gives an alarm.
[0021] The low-pressure steam pipe 6 is provided with a valve 9, and the lower discharge pipe 5 is provided with a valve 10, when the valve 9 is opened, low-pressure steam enters the block area of the tank 2 through the low-pressure steam pipe 6 to dissolve the block.
[0022] Working principle: when the feeding tank is normally working, the valve 9 and the valve 10 are closed, and the pneumatic valve 8 is opened, the liquid is taken out from the feeding pipe 1 into the feeding tank, and then filtered by the block screen 4, and the filtrate falls into the lower discharge area, and then enters the thickener through the lower discharge pipe 1; the block material is intercepted by the block screen 4, and falls into the block area along the inclined slope of the screen.
[0023] In the production process, when it is observed that there are more block materials stored in the block area, the valve 9 is opened, and the low-pressure steam enters the block area of the tank through the low-pressure steam pipe 6, and the heat of the low-pressure steam is used to dissolve the block materials in the block area, after the block materials are completely dissolved, the valve 9 is closed, and the valve 10 is opened, and the dissolved liquid enters the thickener through the lower discharge pipe 10.
[0024] If the lower discharge pipe of the feeding tank is blocked, the liquid level in the tank will rise to the upper limit liquid level, at this time, the pneumatic valve 8 interlocked with the liquid level gauge 7 is automatically closed to stop the liquid, and an alarm is given to remind the staff to repair in time, so as to prevent the problem of liquid overflow in the thickener tank.
