Description

Technical Field

[0001] This invention relates to the field of sodium silicate production, specifically to a water glass solution purification device. Background Technology

[0002] Water glass, an aqueous solution primarily composed of sodium silicate, is widely used in casting, papermaking, ceramics, and detergent industries. Crude water glass contains insoluble matter, including particulate matter and colloids. Purification is necessary to obtain high-quality water glass products. Most existing methods for purifying water glass solutions involve direct filtration. Impurities in water glass solutions fall into two categories: solid particulate matter (quartz sand) and colloids. The presence of colloids puts significant pressure on the filtration system during purification, making filtration quite challenging.

[0003] After conducting a patent search, it was found that the patent application CN201710182440.7, entitled "A purification device and purification method for water glass", uses multi-stage filtration and dilution purification to relieve the pressure in the filtration system. However, this method requires a lot of filtration equipment, and the filtered product needs to be post-processed because of its low concentration, making the process quite complicated. Summary of the Invention

[0004] The purpose of this invention is to provide a water glass solution purification device to solve the above-mentioned problems.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a water glass solution purification device, including a purifier shell, a purification chamber provided inside the purifier shell, a diversion vessel fixedly provided on the inner wall of the top of the purifier shell, two diversion ports facing the middle fixed on both sides of the bottom of the diversion vessel, a hopper provided on the top of the purifier shell, and the hopper and the diversion vessel connected through a feed pipe;

[0006] A purification mechanism is installed in the purification chamber. The purification mechanism includes a main filter screen. The main filter screen is supported by several first rollers that are rotatably connected to the inner wall of the purification chamber. The top part of the main filter screen is supported by several second rollers on the inner side and several first short rollers on the outer side in a wave shape. A first high-pressure jet device is fixedly installed on the inner side of the bottom layer of the main filter screen.

[0007] A slag discharge box is provided at the bottom of the purification mechanism. The bottom of the slag discharge box is connected to a slag discharge pipe, and the bottom of the slag discharge pipe is connected to the outside space. A side slag discharge port is provided on one side of the slag discharge box.

[0008] An auxiliary mechanism is provided on the side of the slag discharge box with a side slag discharge port. The auxiliary mechanism includes a secondary filter screen. The inner side of the secondary filter screen is supported by several third rollers that are rotatably connected to the inner wall of the purification chamber. The outer side of the secondary filter screen is supported by several second short rollers that are rotatably connected to the inner wall of the purification chamber. The secondary filter screen is in contact with the portion between the top of the main filter screen and the slag discharge box. A second high-pressure jet device is provided on the inner side of the secondary filter screen facing the side slag discharge port and fixed to the inner wall of the purification chamber.

[0009] Preferably, a water pump is installed at the bottom of the outer side of the purifier housing, the water pump is connected to the purification chamber through a pipe, and the top of the water pump is connected to the top of the hopper through a return pipe.

[0010] Preferably, a feed valve is installed on the feed pipe, and an inner chamber is provided inside the diverter to connect the feed pipe and the diverter.

[0011] Preferably, two baffles are provided on both sides of the diversion vessel and fixed to the inner wall of the top of the purification chamber, with the bottom of the baffles located near the top of the main filter.

[0012] Preferably, the first high-pressure jet device is connected to a first suction pipe for drawing air from the outside, and the second high-pressure jet device is connected to a second suction pipe for drawing air from the outside.

[0013] Preferably, a base is fixed to the bottom of the purifier housing, and a discharge pipe is installed on the bottom of the outer surface of the purifier housing. A discharge valve is installed on the discharge pipe for opening and closing the discharge pipe.

[0014] Preferably, one of the first rollers is fixed to the motor shaft of the first motor, and the first motor is fixed to the outer surface of the purifier housing; and one of the third rollers is fixed to the motor shaft of the second motor, and the second motor is fixed to the outer surface of the purifier housing.

[0015] Preferably, both the first short roller and the second short roller are relatively short, with their ends extending only 3-5 cm beyond the edges of the corresponding main filter and the secondary filter.

[0016] In summary, the present invention has the following beneficial effects: The present invention purifies water glass solution through direct adsorption using a circulating filter, which is highly efficient. Impurities adsorbed on the filter are removed at the bottom by an air jet device, ensuring the effectiveness of the filter at all times and further improving purification efficiency. The auxiliary filter wrapping around the main filter prevents impurities from falling off, improving impurity removal efficiency. Furthermore, the convection diversion port at the top, together with the baffle, allows the solution to be spread evenly on the main filter, improving adsorption capacity. The wavy top of the main filter also improves the ability to retain impurities. Overall, the purification efficiency is greatly optimized, and the entire filtration system does not experience prolonged filtration pressure, ensuring stable operation and producing a high-quality purified product.

[0030] Advantageously, two baffles 36 are provided on both sides of the diversion vessel 25 and fixed to the top inner wall of the purification chamber 24. The bottom of the baffles 36 is located near the top of the main filter screen 28.

Most of the solid particles and colloids (hereinafter referred to as impurities) in the water glass solution are retained on the upper surface of the main filter screen 28. The wavy shape on the upper surface of the main filter screen 28 can accumulate More impurities will flow into the bottom of the purification chamber 24 after the water glass solution has been purified. The impurities on the main filter screen 28 will move with the main filter screen 28 and be carried by the secondary filter screen 35 until they move to the top of the slag discharge box 31. The impurities on the main filter screen 28 at the top of the slag discharge box 31 will be blown down into the slag discharge pipe 32 by the strong wind of the first high-pressure jet device 38 and discharged. Similarly, the impurities on the secondary filter screen 35 will also be blown into the slag discharge box 31 from the side slag discharge port 33 by the second high-pressure jet device 37 and finally discharged to the outside from the slag discharge pipe 32.

[0041] The water pump 16 operates simultaneously during the purification process, continuously transporting the water glass solution in the purification chamber 24 to the hopper 14 for repeated purification operations.

[0042] After a period of time, the discharge valve 19 can be opened to discharge the purified water glass solution to the required standard.
