[0028] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0029] like Figures 1-4As shown, the present embodiment provides a quantity control structure for the preparation of a collapse preventing agent, comprising a disc frame 1, a collection trough 6 and a hopper fixing frame 701. Inner ring support rods 2 are welded and fixed around the inner wall of the disc frame 1, and a feeding sleeve 503 is arranged between the inner ring support rods 2. The outer wall of the feeding sleeve 503 is supported by the inner ring support rods 2, which can maintain the stable rotation of the internal feeding shaft, and thus can stably deliver the internal raw materials. The top of the feeding sleeve 503 is connected to a powder filling mechanism 5; the output end of the feeding sleeve 503 extends to the inside of the collection trough 6, and the barrel wall of the feeding sleeve 503 is used to fix the connection to the collection trough 6. At the same time, the internal spiral feeding shaft 504 enters the inside of the collection trough 6 to deliver the raw materials. The top of the collection trough 6 is slidably connected to a scraper 601, and the wall thickness of the scraper 601 is less than that of the collection trough 6. The wall thickness can slide down along the discharge port of the feeding sleeve 503 to scrape off the powder at the discharge port. A liquid filling mechanism 4 is provided on the top of the scraper 601, and the liquid filling mechanism 4 is filled by the gravity outflow of the liquid; an electronic weighing device 702 is fixed in the inner cavity of the disc frame 1, and the electronic weighing device 702 uses the principle of piezoelectric sensor to weigh the inorganic compound raw materials fed into the weighing hopper 7. The raw materials for preparing the collapse preventing agent are composed of water, organic compounds and inorganic compounds, among which water and organic compounds account for the majority of the proportion, and the granular crystals in the organic compounds account for the majority. The bottom of the electronic weighing device 702 is detachably connected to the hopper fixing frame 701, and the weighing hopper 7 is embedded in the center of the hopper fixing frame 701. The inner wall of the weighing hopper 7 is smooth, which can reduce the adhesion of the powder.

[0030] like Figure 1-Figure 3 As shown, the powder filling mechanism 5 includes 8 powder silos. The use of the 8 powder silos can be based on the amount of ingredients used by the user when preparing the collapse-preventing agent, and the corresponding amount can be fed in by independently controlling the operation of the motor. The bottom of the powder silo is connected to the inside of the feeding sleeve 503. A spiral feeding shaft 504 is rotatably installed inside the feeding sleeve 503. A feeding motor 501 is installed at one end of the spiral feeding shaft 504. The feeding motor 501 is connected to the inner wall of the disc frame 1 through a fixed block.

[0031] like Figure 3 As shown, the liquid filling mechanism 4 includes a storage barrel, and the bottom valve in the storage barrel is connected to the electromagnetic valve 401. The electromagnetic valve 401 is used to control the circulation of the storage barrel. The outside of the solenoid valve 401 is connected to an electromagnetic flowmeter 402 through a pipe. The electromagnetic flow is based on Faraday's law of electromagnetic induction. When a fluid with a certain conductivity moves to cut magnetic lines of force in a magnetic field, an induced electromotive force will be generated in the fluid. The magnitude of the induced electromotive force is proportional to the magnetic flux density, the inner diameter of the measuring tube and the average flow rate of the fluid. A downpipe 403 is connected to the bottom of the electromagnetic flowmeter 402. When the scraper 601 moves down, the downpipe 403 can be flush with the bottom outlet to prevent water from sticking to the wall of the weighing funnel. The downpipe 403 passes through the scraper 601.

[0032] like Figure 3 As shown, the scraper 601 is close to the inner wall of the aggregate trough 6, and a clamping ring is provided on the periphery of the storage barrel. The outer wall of the clamping ring is integrally connected with a hydraulic rod 602, and the bottom of the hydraulic rod 602 is fixed on the feeding sleeve 503. When the scraper 601 moves downward, the material on the inner wall of the aggregate trough 6 is hung off.

[0033] like Figure 1 and Figure 4 As shown, 8 groups of feeding controllers 502 are distributed on the top of the disc rack 1. The controllers are used to independently control the feeding motor 501. The feeding controllers 502 and the electronic weighing device 702 are both connected to the external control device. A feeding bottom cover 703 is movably installed at the bottom of the weighing hopper 7.

[0034] like Figure 4 As shown, an elastic sealing gasket is glued to the top of the discharge bottom cover 703, and a rotating rod 704 is fixedly connected to the bottom of the discharge bottom cover 703. A discharge motor 705 is installed at one end of the rotating rod 704 away from the discharge bottom cover 703, and the top of the discharge motor 705 is fixed to the outer wall of the weighing hopper 7 through a connecting rod.

[0035] like Figure 1-Figure 3 As shown, the outer walls of the disc frame 1 are symmetrically bolted with lifting and adjusting mechanisms 3 on both sides. The lifting and adjusting mechanism 3 adjusts the height of the feeding device through the limit holes and limit pins to meet the feeding needs of the reactor. A movable seat is provided at the bottom of the lifting and adjusting mechanism 3. The movable seat facilitates the movement of the device and can be flexibly used for feeding on different equipment.

[0036] Working principle of this device: When in use, the device can be pushed to the top of the reactor through the movable seat at the bottom of the lifting and adjusting mechanism 3. Then, according to the type of the prepared collapse preventing agent, the appropriate ingredients are selected and added to the silo of the powder filling mechanism 5. At the same time, deionized water is injected into the storage barrel of the liquid filling mechanism 4 to complete the loading of the prepared raw materials.

[0037] Then, through the external controller, the electromagnetic flowmeter 402 and the electromagnetic valve 401 are turned on, and the deionized water in the storage barrel is discharged from the lower liquid pipe 403. At this time, the bottom cover is in the open state, the scraper 601 is moved downward by the hydraulic rod 602, and the lower liquid pipe 403 is close to the bottom center of the weighing hopper 7. The water column flows out from the bottom center of the weighing hopper 7 into the reactor. At the same time, the electromagnetic flowmeter 402 records the water volume and transmits it to the external control device. When the preset value is reached, the electromagnetic valve 401 is closed to complete the controlled water inlet;

[0038] Then, the unloading motor 705 drives the rotating rod 704 to rotate in the opposite direction, and the elastic sealing gasket on the top of the baffle is stuck in the inside of the weighing hopper 7 to complete the sealing and closing of the weighing hopper 7. According to the feeding order, the external control device is used to notify the corresponding controller to start the feeding motor 501. The feeding motor 501 drives the spiral feeding shaft 504 to rotate, and the powder bin is dropped into the feeding sleeve 503. The powder is sent to the collecting trough 6 through the spiral feeding shaft 504, and then falls into the weighing hopper 7. The weighing hopper 7 is connected to the electronic scale 702 at the top by the hopper fixing frame 701. The electronic scale 702 records the total amount of the weighing hopper 7, which can record the amount of powder. When the set value is reached, the feeding motor 501 stops working, and the hydraulic rod 602 drives the scraper 601 to move downward in the collecting trough 6, and the raw materials on the discharge port on the inner wall of the collecting trough 6 are hung and dropped into the weighing hopper 7 at the bottom, completing the controlled entry of the powder compound.

[0039] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention based on the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
