Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a filtration device and a trough-type cleaning machine circulation system. Background Technology

[0002] As a crucial piece of equipment in wet process cleaning, the tank cleaning machine involves an unavoidable process of chemical solution circulation and overflow, making the use of the circulation pump extremely important. The circulation pump is a vital tool for achieving chemical solution circulation in the tank cleaning machine. Generally, the tank consists of a main tank and a secondary tank. The circulation pump pressurizes water from the secondary tank and pumps it into the main tank to create internal circulation, thus achieving the overflow effect. If other objects accidentally fall into the tank or silicon wafer fragments are not cleaned up in time, they will also be sucked into the circulation pump, which will seriously affect the service life of the circulation pump over time.

[0003] Currently, traditional filter screens or filter cartridges are typically installed inside the tank to filter impurities. However, due to overflow circulation, other impurities can be sucked into the circulation pump, causing pump malfunctions. Additionally, installing filter screens inside the tank affects water flow rate, thus impacting overflow efficiency. Furthermore, traditional filter screens or filter cartridges are inconvenient to install and remove, and cannot be reused without maintenance and cleaning.

[0004] Based on this, the present invention provides a filtration device and a tank-type cleaning machine circulation system to solve the problems mentioned above. Utility Model Content

[0030] The filtration device and the circulation system of the tank-type cleaning machine of this utility model will be described in more detail below with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of this utility model. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit this utility model.

[0031] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0032] Example 1

[0033] like Figure 1 and Figure 2 As shown in the figure, this embodiment proposes a filtration device, including a bottle body 1, a sealing cap 2, and a filter screen 3.

[0034] The bottle body 1 has an open design at one end and a water outlet (not shown in the figure) at the other end; the sealing cap 2 is detachably installed at the open end of the bottle body 1 and has a water inlet 21 on the sealing cap 2; the filter screen 3 passes through the open end of the bottle body 1 and is positioned inside the bottle body 1 in conjunction with the sealing cap 2.

[0035] In the above embodiment, specifically, an elastic sealing sleeve 4 is installed around the filter screen 3, and a placement groove 11 for placing the elastic sealing sleeve 4 is provided on the inner side wall of the opening end of the bottle body 1.

[0036] When the elastic sealing sleeve 4 is placed in the placement groove 11, the outer wall of the elastic sealing sleeve 4 is in close contact with the side wall of the placement groove 11; and when the sealing cap 2 is installed on the bottle body 1, the end faces of the sealing cap 2 and the elastic sealing sleeve 4 are in close contact with each other, thereby realizing the positioning and placement of the filter screen 3 in the bottle body 1.

[0037] When the medium enters the bottle 1 through the inlet 21, due to the setting of the elastic sealing sleeve 4, the medium will not be directly discharged from the bottle 1 through the outlet. Instead, it will be filtered by the filter screen 3 before being discharged through the outlet.

[0038] Over time, filter screen 3 will intercept a large amount of impurities. When these impurities accumulate excessively, they will clog the mesh openings of filter screen 3. When filter screen 3 is clogged, the resistance to the medium passing through it increases, thus requiring cleaning. To clean filter screen 3, simply remove the sealing cap 2, and then easily remove filter screen 2 from the bottle body 1 for rinsing; the operation is simple. The sealing cap 2 can be connected to the bottle body 1 by a threaded connection. Furthermore, to facilitate the installation or removal of the sealing cap 2, a hexagonal head 22 is provided on the sealing cap 2.

[0039] In the above embodiments, optionally, the elastic sealing sleeve 4 can be detachably installed on the filter screen 3, thereby realizing the replaceability of the elastic sealing sleeve 4 to ensure a good filtration effect of the filtration device.

[0040] Specifically, refer to Figure 3 The filter screen 3 has a limiting protrusion 31 on its side wall, and the inner side wall of the elastic sealing sleeve 4 has a limiting groove 41 that matches the limiting protrusion 31. The elastic sealing sleeve 4 is fitted onto the filter screen 3, and the limiting groove 41 aligns with the limiting protrusion 31, achieving stable installation of the elastic sealing sleeve 4. When it is necessary to disassemble the elastic sealing sleeve 4, simply apply force to push it; the operation is simple.

[0041] In the above embodiment, preferably, a flow meter 5 is installed at the water outlet to monitor the water flow rate at the outlet. The monitoring data can be used to understand the usage of the filter screen 3 in real time, so that the filter screen 3 can be cleaned and maintained in a timely manner.

[0042] In a preferred embodiment, the filter screen 3 preferably adopts a sleeve-type structure with only one end open, and when the filter screen 3 is positioned inside the bottle body 1, the open end of the filter screen 3 faces the sealing cap 2.

[0043] Filter screen 3 adopts a sleeve-type structure, which has the following advantages:

[0044] (1) Compared with a flat filter, the cylindrical design has a much larger surface area, which allows for more filtration area in the same space.

[0045] (2) The cylindrical design allows the fluid to be distributed more evenly on the filter surface as it passes through. For liquid filtration, the liquid can flow along the outer or inner surface of the cylinder, avoiding situations where the flow rate is too fast or too slow in certain areas;

[0046] (3) The cylindrical design helps to reduce the pressure loss of fluid during the filtration process. In fluid mechanics, when fluid passes through irregular or narrow channels, it will generate a large pressure loss. However, the internal and external spaces of the cylindrical filter screen are relatively regular, and the resistance of the fluid when passing through is small.

[0047] (4) The cylindrical design makes it easy to clean or replace. Its shape is relatively regular. When cleaning, it can be cleaned by rinsing, soaking and other methods.

[0048] In one specific embodiment, the mesh size of the filter screen 3 is 0.5-1mm.

[0049] For applications of filtration devices in the circulation system of a trough-type cleaning machine, excessively large mesh openings will not achieve the required filtration effect, while excessively small mesh openings will inevitably increase the frequency of filter maintenance and cleaning, thus affecting the normal operation of the trough-type cleaning machine. By setting the mesh opening diameter of filter screen 3 to 0.5-1mm, good performance of the filtration device in the circulation system of the trough-type cleaning machine is guaranteed.

[0050] Example 2

[0051] Combined with reference Figure 4 This embodiment proposes a trough-type cleaning machine circulation system, including a circulation pump 01, a secondary trough 02, and a filtration device as described in Embodiment 1.

[0052] The inlet 21 and outlet of the filter device are connected to the secondary tank 02 and the circulation pump 01 through pipelines, respectively, for filtering the medium entering the circulation pump 01 from the secondary tank 02;

[0053] The circulating pump 01 and the auxiliary tank 02 are respectively connected to the main process tank 05 of the tank cleaning machine through the circulating pipeline 03 and the overflow pipeline 04.

[0054] In the above embodiment, the main process tank 05 needs to overflow during operation. Due to the overflow, the liquid in the main process tank 05 will enter the secondary tank 02 from its overflow area 051 through the overflow pipe 04. The water in the secondary tank 02 is filtered by the filter device and then enters the circulation pump 01. The circulation pump 01 pressurizes and sends the liquid back into the main process tank 05 through the circulation pipeline 03 to form a circulation action.

[0055] During the circulation of the pharmaceutical solution, the filter screen 3 in the filtration device before the solution enters the circulation pump 01 effectively filters various fragments and other debris generated in the main process tank 05, preventing debris from affecting the operation of the circulation pump 01 and ensuring that the overflow effect of the main process tank 05 is not affected. The flow meter 5 in the filtration device can also monitor the flow rate of the pharmaceutical solution discharged from the bottle 1 of the filtration device in real time. Based on the monitoring data, the filter screen 3 can be removed and washed in a timely manner, allowing for its reuse.

[0056] Furthermore, the filter screen 3 has a mesh opening diameter of 0.5mm-1mm and adopts a sleeve-type structure with only one end open. While ensuring effective filtration of impurities, the maintenance and cleaning frequency of the filter screen 3 is also effectively guaranteed, and it is convenient to clean the filter screen 3.

[0057] In the above implementation process, when disassembling the filter screen 3, in order to avoid disassembling the filter device installed in the circulation system of the tank cleaning machine as a whole, a hose or telescopic pipe can be used to connect the water inlet 21 on the sealing cover 2 to the secondary tank 02.

[0058] In summary, compared with the prior art, this utility model has at least the following advantages:

[0059] (1) The filter device provided by this utility model positions and places the filter screen through the bottle body and the sealing cap. At the same time, the sealing cap and the bottle body adopt a detachable installation method. When the filter screen needs to be cleaned and maintained, simply remove the sealing cap and take the filter screen out of the bottle body for cleaning. The operation is simple.

[0060] (2) The trough cleaning machine circulation system provided by this utility model can achieve pre-filtration of the medium entering the circulation without affecting the overflow speed in the trough by installing a filter device at the inlet of the circulation pump. This effectively avoids impurities from entering the circulation pump and affecting its operation. At the same time, the filter device is easy to clean and maintain in the trough cleaning machine circulation system provided by this utility model, which effectively ensures the stable and efficient operation of the trough cleaning machine.

[0061] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
