Description

Technical Field

[0001] This utility model relates to the field of plate cooler technology, specifically to an anti-clogging plate cooler. Background Technology

[0002] A plate cooler is a new type of high-efficiency heat exchanger composed of a series of metal plates with a certain corrugated shape. It mainly consists of a frame and plates, which are stacked between fixed and movable clamping plates and then clamped together with clamping bolts.

[0003] For example, an existing Chinese patent (CN202092496U) discloses a semi-welded plate heat exchanger, including a fixed clamping plate, a movable pressure plate, an upper guide rod, a lower guide rod, a support column, pairs of semi-welded plates, sealing gaskets, and clamping bolt pairs. The fixed clamping plate, movable pressure plate, upper guide rod, lower guide rod, and support column constitute the frame of the heat exchanger. Multiple pairs of semi-welded plates are assembled together by sealing gaskets to form a plate bundle. The plate bundle is positioned between the fixed clamping plate and the movable pressure plate and fixed by clamping bolt pairs. The sealing between the multiple pairs of semi-welded plates on the plate bundle is achieved using sealing gaskets. Furthermore, the sealing between two plates A and B of each semi-welded plate pair employs a double-sided laser welding structure, effectively overcoming deformation during plate welding and eliminating welding stress. This utility model has a simple and reasonable structure, is easy to use, and provides good heat exchange performance.

[0004] Existing plate heat exchangers have relatively narrow heat exchange medium channels between the plates, typically only about 5 mm. Therefore, using this equipment requires a high degree of cleanliness of the heat exchange medium. If the cooling medium contains suspended solid particles or other foreign matter, these impurities may enter the gaps between the plates, causing blockage. To address this, an anti-clogging plate cooler is provided. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging plate cooler to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging plate cooler, comprising: a first clamping plate, a plate, and a second clamping plate, with a plate disposed between the first clamping plate and the second clamping plate; upper connecting pipes disposed on both sides of the top of the second clamping plate; lower connecting pipes disposed on both sides of the bottom of the second clamping plate; a filter housing disposed between the upper connecting pipes and the lower connecting pipes; a bottom plate disposed at the bottom end of the filter housing; a pad disposed on the top of the bottom plate; a support plate disposed on the top of the pad; a filter element disposed on the top of the support plate; a conical shell disposed on the top of the filter element; a connecting water pipe disposed on one side of the conical shell; and a drain valve disposed on one side of the outer wall of the filter housing.

[0007] Furthermore, the drain valve is located on one side of the bottom of the conical housing, and the end of the conical housing with the larger diameter at the bottom is in contact with the filter element.

[0008] Furthermore, a connecting column is provided at the center of the top of the support plate, and a partition is provided between the outer wall of the connecting column and the inner wall of the filter housing. There are three partitions, and the three partitions are evenly arranged circumferentially on the support plate.

[0009] Furthermore, there are three filter elements, which are fixed between the partitions.

[0010] Furthermore, the bottom end of the connecting water pipe faces the top surface of the filter element, and the water outlet of the filter element penetrates through the support plate.

[0011] Furthermore, the first clamping plate and the second clamping plate are fixed together by bolts, and several connecting flanges are provided on one side of the first clamping plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the design of a first clamping plate, a filter housing, and a filter element, achieves the following in the anti-clogging plate cooler: when the medium passes through the upper and lower connecting pipes, it passes through the filter housing. When the medium falls from the upper connecting pipe, it first passes through the conical shell. The design of the water pipe connected to the conical shell allows a portion of the medium to directly enter the filter element for filtration, while another portion settles in the space outside the conical shell before entering the filter element. Impurities are partially filtered directly by the filter element, and some accumulate on the bottom outside of the conical shell, being periodically discharged through a drain valve. The filtered medium is then circulated through the lower connecting pipe. Conversely, when the medium rises from the lower connecting pipe, it first passes through the filter element, then rises into the outer side of the conical shell for settling, and finally circulates through the upper connecting pipe. This design prevents impurities in the medium from clogging the plates, improving the anti-clogging performance of the plate cooler.

[0014] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4 This utility model provides a technical solution: an anti-clogging plate cooler, comprising: a first clamping plate 1, a plate 2, and a second clamping plate 3. The plate 2 is provided between the first clamping plate 1 and the second clamping plate 3. The upper connecting pipes 4 are provided on both sides of the top of the second clamping plate 3, and the lower connecting pipes 7 are provided on both sides of the bottom of the second clamping plate 3. A filter housing 5 is provided between the upper connecting pipes 4 and the lower connecting pipes 7. The bottom end of the filter housing 5 is provided with a bottom plate 8. The top of the bottom plate 8 is provided with a pad 9. The top of the pad 9 is provided with a support plate 10. The top of the support plate 10 is provided with a filter element 12. The top of the filter element 12 is provided with a conical housing 13. A connecting water pipe 14 is provided on one side of the conical housing 13. A drain valve 6 is provided on one side of the outer wall of the filter housing 5. When the medium passes through the upper connecting pipe 4 and the lower connecting pipe 5, it will pass through the filter housing 5. When the medium falls from the upper connecting pipe 4, it first passes through the conical housing 13. Through the design of the water pipe 14 on the conical housing 13, a part of the medium can directly enter the filter element 12 for filtration through the water pipe 14. The other part of the medium will settle in the space outside the conical housing 13. The medium that does not pass the top of the water pipe 14 will enter the filter element 12 for filtration.

[0022] The drain valve 6 is located on one side of the bottom of the conical housing 13, with the larger diameter end of the bottom of the conical housing 13 in contact with the filter element 12. The medium that has not passed the top of the connecting water pipe 14 enters the filter element 12 for filtration. Some impurities are directly filtered through the filter element 12, while others accumulate on the outside of the bottom of the conical housing 13 and are periodically discharged through the drain valve 6.

[0023] A connecting column 15 is located at the center of the top of the support plate 10. Three partitions 11 are arranged circumferentially on the support plate 10 between the outer wall of the connecting column 15 and the inner wall of the filter housing 5. Three filter elements 12 are fixed between the partitions 11. The arrangement of multiple filter elements 12 ensures that the filter screen size is appropriate and the position is reasonable, effectively blocking impurities from entering the cooler while improving water flow efficiency.

[0024] The bottom end of the connecting water pipe 14 faces the top surface of the filter element 12, and the outlet of the filter element 12 passes through the support plate 10. The first clamping plate 1 and the second clamping plate 3 are fixed together by bolts, and several connecting flanges are provided on one side of the first clamping plate 1. The bolts clamp the various plates 2 to form a thin rectangular channel, through which heat exchange occurs.

[0025] When the anti-clogging plate cooler is in use, the medium passes through the upper connecting pipe 4 and the lower connecting pipe 7, and then through the filter housing 5. When the medium falls from the upper connecting pipe 4, it first passes through the conical housing 13. Due to the design of the water connecting pipe 14 on the conical housing 13, part of the medium directly enters the filter element 12 for filtration through the water connecting pipe 14, while the other part of the medium settles in the space outside the conical housing 13. The medium that does not reach the top of the water connecting pipe 14 then enters the filter element 12 for filtration. Some impurities are directly filtered through the filter element 12, while some accumulate on the bottom outside of the conical housing 13 and are periodically discharged through the drain valve 6. The filtered medium is then circulated through the lower connecting pipe 7 for filtration. Conversely, when the medium rises from the lower connecting pipe 7, it first passes through the filter element 12 for filtration, then rises into the outside of the conical housing 13 for sedimentation, and finally circulates through the upper connecting pipe 4 for filtration. This prevents impurities in the medium from clogging the plates and improves the anti-clogging performance of the plate cooler.

[0026] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
