Description

Technical Field

[0001] This utility model relates to the technical field of toner filtration equipment, and in particular to a dual-barrel toner filtration device. Background Technology

[0002] In the existing technology, activated carbon treatment filters used for plastic electroplating are usually configured with a filter tank and a chemical tank. The disadvantage is that the efficiency is low and there is room for improvement. Utility Model Content

[0003] This invention provides a dual-barrel toner filter device to solve the technical problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A dual-barrel toner filtration device includes a frame, and a first filter barrel, a second filter barrel, and a dosing tank mounted on the frame. A filter pump is located at the bottom of the frame. The filter pump has an inlet and an outlet at its two ends. A first-way tee fitting is installed at the outlet of the filter pump. The first port of the first-way tee fitting is connected to the outlet of the filter pump. The second port has a first liquid distribution pipe connected to the inlet / outlet of the first filter barrel. The third port has the first filter barrel connected to the inlet / outlet of the second filter barrel. Valves are installed on the three ports of the first-way tee fitting. An exhaust valve and a circulation pipe are located on one side of the top of the first and second filter barrels. The other ends of both circulation pipes are connected to the dosing tank. A dosing pipe is located between the outlet of the dosing tank and the inlet of the filter pump, and a dosing valve is installed on the dosing pipe.

[0006] It also includes a No. 2 tee fitting and a second liquid distribution pipe. The first port of the No. 2 tee fitting is connected to the outlet end of the second liquid distribution pipe, the second port is connected to the inlet / outlet of the second filter bucket, and a drain port is provided at the third port. A valve is installed on the third port of the No. 2 tee fitting.

[0007] As a further preferred embodiment of this utility model, the No. 1 tee fitting and the No. 2 tee fitting are positive tees.

[0008] As a further preferred embodiment of this invention, a pressure gauge is also installed on the exhaust valve.

[0009] As a further preferred embodiment of this utility model, the frame is a hollow rectangular structure; the upper end of the frame is provided with an installation platform, on which the first filter tank, the second filter tank and the dosing tank are all fixedly installed, and the filter pump is located below the installation platform.

[0010] As a further preferred embodiment of this utility model, universal casters are installed at the four corners of the bottom of the frame.

[0011] As a further preferred embodiment of this invention, a control switch is installed on the frame located on the pump side of the filter.

[0012] As a further preferred embodiment of this utility model, the filter pump is a self-priming pump that is resistant to dry running, which has better sealing performance than ordinary centrifugal pumps. Furthermore, after the motor stops, the water in the pump casing will not automatically drain. The motor drives the turbine to rotate at high speed, which quickly creates a negative pressure (vacuum) inside the pump. The air pressure is used to force the water onto the pump casing, and then centrifugal head is achieved.

[0013] Compared with the prior art, the present invention has the following advantages or beneficial effects:

[0014] This utility model provides a dual-barrel toner filtration device that adds a second filter after the conventional single-stage filter, providing two filtration channels for a smoother filtration process and the ability to handle larger volumes of toner. The two filter barrels combined form a two-stage filtration structure, significantly improving filtration efficiency and ensuring optimal filtration results. The filter pump is connected to both filter barrels via a three-way fitting, which changes the fluid direction, simultaneously delivering the toner treatment solution to both barrels. Valves allow for both inlet and outlet operations. The bottom of each barrel has only one inlet / outlet, simplifying the piping structure and making internal frame installation easier and faster, while also facilitating pipe maintenance. The first filter barrel can be used alone, or both can be used simultaneously, sharing a single dosing tank. The operator can choose the appropriate method based on the specific situation, offering flexible application options. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-2 As shown, the dual-barrel toner filtration device provided in this embodiment includes a frame 1, and a first filter barrel 2, a second filter barrel 3, and a dosing tank 4 installed on the frame 1. A filter pump 5 is located at the bottom of the frame 1. The filter pump 5 has an inlet 6 and an outlet at its two ends. A first-way three-way fitting 14 is installed at the outlet of the filter pump 5. The first port of the first-way three-way fitting 14 is connected to the outlet of the filter pump 5, the second port has a first liquid distribution pipe 8 connected to the inlet / outlet port at the bottom of the first filter barrel 2, and the third port is connected to the first filter barrel 2 and the second filter barrel 3. Valves are installed on the three ports of the first-way three-way fitting 14. An exhaust valve 10 and a circulation pipe 11 are located on one side of the top of the first filter barrel 2 and the second filter barrel 3. The other ends of both circulation pipes 11 are connected to the dosing tank 4. A dosing pipe 12 is located between the outlet of the dosing tank 4 and the inlet of the filter pump 5, and a dosing valve 13 is installed on the dosing pipe 12. It also includes a No. 2 tee fitting 15, the first port of which is connected to the outlet end of the second liquid separator 9, the second port of which is connected to the inlet / outlet of the second filter tank 3, and a drain port 16 is provided at the third port. A valve is installed on the third port of the No. 2 tee fitting 15.

[0021] To further explain, the No. 1 tee fitting 14 and the No. 2 tee fitting 15 are positive tees used to change the direction of fluid flow. Together with the valves on the ports, they allow for liquid inlet and outlet. The vent valve 9 is also equipped with a pressure gauge to detect and control pressure changes within the tank. When the pressure inside the tank becomes too high, the pressure gauge will indicate this, requiring the vent valve to reduce the pressure inside the tank to prevent explosions or leaks.

[0022] To further explain, the frame 1 has a hollow rectangular structure. A mounting platform is provided at the top of the frame 1, on which the first filter tank 2, the second filter tank 3, and the dosing tank 4 are all fixedly mounted. The filter pump 5 and the piping are located below the mounting platform. Universal casters 17 are installed at the four corners of the bottom of the frame 1. A control switch 18 for easy operation by the user is located on the frame next to the filter pump 5.

[0023] The working principle of the dual-barrel toner filter device provided in this embodiment is as follows:

[0024] After pressing the control switch 18 to start the filter pump 5, the inlet 6 and outlet 19 are connected to an open water tank. The carbon treatment solution to be filtered is drawn into the water tank through the inlet 6 of the filter pump 5. At the same time, the valves on the three ports of the first three-way fitting 14 are opened, and the valve on the third port of the second three-way fitting 15 is closed. The solution enters the first filter tank 2 and the second filter tank 3 through the three-way fitting and the inlet / outlet. When the solution completely fills the filter tank, the inlet 6 of the filter pump 5 can no longer draw in the excess solution. The chemical solution is placed in the dosing tank 4. The chemical solution contains filter aid powder and activated carbon powder. The dosing valve 13 at the bottom of the dosing tank 4 is opened, and the chemical solution is drawn into the two tanks through the dosing pipe 12 with the dosing valve 13. The valve on the circulation pipe 11 is opened to form a circulation loop, so that the solution and the chemical solution continuously circulate and mix in the tanks, achieving a uniform mixing effect. During the tank solution circulation and mixing process, a pressure gauge monitors the pressure inside the filter tank to maintain a uniform pressure. After filtration, the dosing valve 13 is closed, and the valve on the circulation pipe 11 is opened to release the tank solution containing the chemical solution into the dosing tank 4. The operator obtains a sample solution from the dosing tank 4 for testing. When the sample solution meets the actual filtration requirements, the filtration operation is completed. The valve on the first port of the No. 1 tee fitting 14 is closed, and the valve on the third port of the No. 2 tee fitting 15 is opened, draining the tank solution from both tanks through the drain port 16. If the sample solution fails the test, the operator can add new chemical solution and repeat the above steps to continuously circulate and mix the tank solution and chemical solution in the filter tank until the actual filtration requirements are met.

[0025] The first filter tank can be used alone, or both filter tanks can be used simultaneously, sharing a single dosing tank. The operator can choose the appropriate method based on the specific situation, offering flexibility. The specific operation is as follows: When both filter tanks are needed, the valve on the third port of the No. 1 tee fitting 14 can be opened, connecting the outlet of the filter pump 5 to the second distributor pipe 9. When only the first filter tank 2 needs to be used, the valve on the third port of the No. 1 tee fitting 14 can be closed. Since the tee fitting is located at the bottom of both tanks, liquid inlet and outlet can be achieved by changing the fluid direction. Therefore, there is no need to separately install inlet and outlet ports on the tanks, reducing the amount of piping required and simplifying the overall structure. This also facilitates pipeline maintenance.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
