Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a multifunctional ammonium metatungstate concentrate filtration device. Background Technology

[0002] In the production of ammonium metatungstate, the filtration of the concentrate is a crucial step. Due to its inherent viscosity, ammonium metatungstate concentrate has poor flowability, a characteristic that often leads to low filtration efficiency in traditional filtration systems. Traditional filtration devices typically rely on gravity or simple pressure differences to propel the concentrate through the filter media. However, for the highly viscous ammonium metatungstate concentrate, this driving method is often insufficient to overcome its internal resistance, resulting in slow filtration speeds and potentially even clogging of the filter media, severely impacting production efficiency and product quality.

[0003] Furthermore, as filtration time increases, impurities and residues gradually accumulate inside the filter canister. This dirt not only reduces filtration efficiency but can also contaminate subsequent filtration processes, affecting product purity. Therefore, regular cleaning and maintenance of the filter canister is essential. However, traditional cleaning methods are often inefficient, failing to thoroughly remove dirt from the filter canister, and are cumbersome, increasing production costs and labor intensity. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional ammonium metatungstate concentrate filtration device to solve the technical problems of low efficiency and cumbersome and difficult cleaning of dirt in the filter tank when filtering ammonium metatungstate concentrate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a multifunctional ammonium metatungstate concentrate filtration device, the multifunctional ammonium metatungstate concentrate filtration device comprising:

[0006] The main tank has a concentrate outlet at the bottom and a concentrate inlet at the top.

[0007] A filter canister is disposed inside the main body canister, and the edge of the filter canister is tightly fitted to the inner wall of the main body canister.

[0008] A drain outlet is provided on the side of the main body bucket, and the position of the drain outlet is higher than the top of the filter bucket;

[0009] The Y-shaped pipe has its main body connected to the main tank, and the connection point between the Y-shaped pipe and the main tank is lower than the top of the filter tank. The first branch of the Y-shaped pipe is connected to a tap water pipe, and the second branch of the Y-shaped pipe is connected to a vacuum pump. Electromagnetic valves are installed on the concentrate outlet, concentrate inlet, sewage outlet, first branch pipe, and second branch pipe.

[0010] The control module is electrically connected to the vacuum pump and the solenoid valve.

[0011] In one embodiment, an electronic pressure gauge is also included, which is disposed on the main body barrel and is located below the top of the filter barrel. The electronic pressure gauge is electrically connected to the control module.

[0012] In one embodiment, the filter cartridge is made of stainless steel or ceramic material.

[0013] In one embodiment, the bottom of the filter barrel is provided with a plurality of filter holes evenly distributed.

[0014] In one embodiment, the inner wall of the main barrel is provided with an anti-corrosion coating, which is made of acid and alkali resistant materials.

[0016] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages:

[0017] This utility model provides a multifunctional ammonium metatungstate concentrate filtration device. A vacuum pump creates a vacuum in the filtered area of ​​the main tank, resulting in a higher air pressure inside the filter tank (before filtration) than outside (after filtration). This pressure difference effectively overcomes the viscous resistance of the ammonium metatungstate concentrate, propelling it through the filter tank more quickly and significantly improving filtration efficiency. After prolonged filtration, the filter tank can be cleaned by controlling the operation of relevant solenoid valves and the vacuum pump via a control module, enabling backwashing. During backwashing, water is supplied through a Y-shaped pipe into the main tank, while the reverse-operating vacuum pump pumps air into the tank, creating bubbles in the water and generating a cavitation effect. This cavitation effect more effectively removes and cleans dirt from the filter tank, improving the backwashing effect and maintaining the filter's filtration function. Attached Figure Description

[0027] Please see Figures 1 to 2 This application provides a multifunctional ammonium metatungstate concentrate filtration device, including a main tank 1, a filter tank 2, a drain outlet 3, a Y-shaped pipe 4, and a control module. The main tank 1 has a concentrate outlet 11 at its bottom and a concentrate inlet 12 at its top. The filter tank 2 is located inside the main tank 1, with its edge tightly fitted to the inner wall of the main tank 1. The drain outlet 3 is located on the side of the main tank 1, and its position is higher than the top of the filter tank 2. The main pipe 41 of the Y-shaped pipe 4 is connected to the main tank 1, and the connection point between the Y-shaped pipe 4 and the main tank 1 is lower than the top of the filter tank 2. The first branch pipe 42 of the Y-shaped pipe 4 is connected to a water pipe, and the second branch pipe 43 is connected to a vacuum pump. Electromagnetic valves 5 are installed on the concentrate outlet 11, concentrate inlet 12, drain outlet 3, first branch pipe 42, and second branch pipe 43. The control module is electrically connected to the vacuum pump and the electromagnetic valves 5.

[0028] During filtration, the control module controls the opening of the solenoid valves 5 on the concentrate outlet 11, concentrate inlet 12, and second branch pipe 43 (while closing the other valves), and controls the vacuum pump to operate in the forward direction. The ammonium metatungstate concentrate enters through the concentrate inlet 12 and is filtered by the filter tank 2. Because the ammonium metatungstate concentrate has a certain viscosity, its flowability is poor, which easily leads to low filtration efficiency. This application addresses this by using a vacuum pump to evacuate the filtered area inside the main tank 1, making the air pressure inside the filter tank 2 (the area before filtration) greater than the air pressure outside the filter tank 2 (the area after filtration), thereby improving filtration efficiency. After prolonged filtration, in order to clean the filter canister 2, the control module can close the solenoid valves 5 on the concentrate outlet 11 and concentrate inlet 12, open the other solenoid valves 5, and control the vacuum pump to work in reverse, so that the tap water pipe passes through the Y-shaped pipe 4 to introduce cleaning water into the main tank 1 to backwash the filter canister 2. The vacuum pump working in reverse will also pump air into the main tank 1, forming bubbles in the cleaning water and generating a cavitation effect, which improves the backwashing effect and the cleaning effect of the filter canister 2, so as to maintain the filtration function of the filter canister 2.

[0029] The control module is existing technology, specifically a programmable logic controller (PLC). The connection circuit between the PLC and the vacuum pump and the solenoid valve 5, as well as the specific control principle, are existing technologies. This application has not made any improvements to this part, so this part is omitted.

[0030] In one embodiment, an electronic pressure gauge 6 is also included. The electronic pressure gauge 6 is mounted on the main body barrel 1, and is positioned below the top of the filter barrel 2. The electronic pressure gauge 6 is electrically connected to the control module. The electronic pressure gauge 6 can monitor the air pressure on the outside of the filter barrel 2 (the filtered area) in real time and feed the air pressure value back to the control module. The control module controls the output power of the vacuum pump based on the air pressure value, thereby controlling the pressure difference between the inside and outside of the filter barrel 2 during filtration. This ensures the filtration effect while preventing excessive pressure difference from damaging the filter barrel 2.

[0031] In one embodiment, the filter cartridge 2 is made of stainless steel or ceramic material. Both stainless steel and ceramic materials have good corrosion resistance, which can resist the erosion of chemicals in ammonium metatungstate concentrate and extend the service life of the filter cartridge 2. Furthermore, stainless steel has a smooth surface and is not easy to accumulate dirt; while ceramic material has self-cleaning properties, making it easy to clean and maintain.

[0032] In one embodiment, the bottom of the filter bucket 2 is provided with a plurality of filter holes evenly distributed.

[0033] In one embodiment, the inner wall of the main tank 1 is provided with an anti-corrosion coating made of acid and alkali resistant materials. The anti-corrosion coating can effectively resist the corrosion of the inner wall of the main tank 1 by acid and alkali substances in the ammonium metatungstate concentrate, thus extending the service life of the main tank 1.

[0034] In one embodiment, an observation window 7 is also provided on the side of the main tank 1. The observation window 7 is made of a transparent and corrosion-resistant material. The observation window 7 allows the operator to directly observe the filtration status inside the main tank 1, including the filtration progress, filtration effect, and possible abnormalities. In addition, through the observation window 7, the operator can adjust the filtration parameters or take necessary maintenance measures in a timely manner, improving the efficiency and accuracy of the filtration operation.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
