Description

Technical Field

[0001] The utility model belongs to the technical field of filters and relates to a sintered plate filter which is convenient for replacing filter elements. Background Art

[0002] Sintered plate filter is a gas filtering device with sintered porous filter material (filter element) as the core. When using sintered porous filter material, in order to increase the contact area between the filter element and the dust gas and improve the filtering effect, the filter element is mostly designed to be pleated. Therefore, when installing the filter element, it is usually fixed on the connecting piece by pouring, and then fixed in the dust removal chamber by the connecting piece. Therefore, it is not convenient to replace the damaged filter element. For this reason, we propose a sintered plate filter that is easy to replace the filter element.

[0003] A sintered plate filter that is easy to replace filter elements is disclosed in Chinese patent CN211097968U. The filter includes two sets of upper and lower connecting seats and filter elements. The filter elements are inserted into the connecting seats. The outer walls on the left and right sides of the top connecting seat are provided with grooves. A reinforcement plate is slidably connected in the groove. The reinforcement plate cooperates with a block to provide auxiliary support for the filter element.

[0004] When using the filter, first insert the two sets of connecting seats into the two ends of the filter element, then translate and insert the block into the groove of the filter element. The block and the reinforcement plate can reinforce the filter element. Pull the pull plate to the front and rear sides and then insert the reinforcement plate downward into the slot. When the reinforcement plate is inserted, the insertion rod will be pushed to both sides. At this time, the spring will be stretched. When the positioning hole set on the outer wall of the reinforcement plate is inserted into the insertion rod position, the spring drives the insertion rod to reset and insert it into the positioning hole to fix the bottom of the reinforcement plate. At this time, release the pull plate, and the reset spring will drive the pull plate to reset and insert the insertion plate into the reinforcement plate to fix its top. When installing, the reinforcement plate, block, connecting seat, etc. are all separate parts, which need to be positioned separately before being fixed, which is inconvenient to operate.

[0005] In order to solve the above problems, the utility model proposes a sintered plate filter which is convenient for replacing filter elements. Utility Model Content

One rotating drum 5 is slidably provided on the left side of the filter element 1, and the other rotating drum 5 is slidably provided on the right side of the filter element 1, so that the two rotating drums 5 preliminarily position the filter element 1.

[0026] The bottom of the left end of the upper connecting seat 2 and the top of the right end of the lower connecting seat 3 are both symmetrically fixedly connected with two mounting plates 4, and the rotating drum 5 is rotatably connected between the corresponding two mounting plates 4.

[0027] The outer surface of the rotating drum 5 is fixedly connected with a limit plate 16, which is respectively matched with the upper connecting seat 2 and the lower connecting seat 3. When the rotating drum 5 rotates, the limit plate 16 will contact the lower surface of the upper connecting seat 2 to limit the rotation angle of the rotating drum 5.

[0028] Both ends of the rotating drum 5 are fixedly connected with a sleeve 6, a slide rod 9 is slidably arranged inside the sleeve 6, and a positioning hole 10 is opened at one end of the slide rod 9 away from the sleeve 6. The sleeve 6 and the slide rod 9 are connected by a connecting piece.

[0029] The connecting member includes a first spring 7. A connecting plate 8 is fixedly connected to the end of the slide rod 9, and the connecting plate 8 is slidably connected to the inside of the sleeve 6. The first spring 7 is fixedly connected between the inner wall of the sleeve 6 and the connecting plate 8. The shape of the connecting plate 8 is adapted to the shape of the inside of the sleeve 6, and the end of the slide rod 9 is positioned on the sleeve 6 through the connecting plate 8.

[0030] The right end of the upper connecting seat 2 and the left end of the lower connecting seat 3 are both symmetrically fixedly connected with two supporting plates 11, and the sliding rod 9 is slidably matched with the corresponding supporting plates 11. A positioning rod 15 is slidably arranged inside each supporting plate 11.

[0031] The upper connecting seat 2 and the lower connecting seat 3 are both provided with telescopic components, and the telescopic components drive the positioning rod 15 to slide in the corresponding supporting plate 11 .

[0032] The telescopic assembly includes a second spring 14. The bottom of the right end of the upper connecting seat 2 and the top of the left end of the lower connecting seat 3 are both fixedly connected with a fixing plate 12, and the fixing plate 12 is located between the corresponding two supporting plates 11. The two ends of the second spring 14 are respectively fixedly connected to the two side surfaces of the fixing plate 12 close to the corresponding positioning rod 15.

[0033] Both sides of the fixing plate 12 are fixedly connected with fixing rods 13 , ends of the fixing rods 13 are slidably disposed in corresponding positioning rods 15 , and the second springs 14 are sleeved on the corresponding fixing rods 13 .

[0034] When the end of the sliding rod 9 slides to one side of the corresponding supporting plate 11 , the end of the positioning rod 15 is slidably disposed in the positioning hole 10 .

[0035] Working principle:

[0036] When in use, the filter element 1 is first moved to the top of the lower connecting seat 3 and located on one side of the drum 5. Then the upper connecting seat 2 is moved to the top of the filter element 1 so that the drum 5 on the upper connecting seat 2 is located on the other side of the filter element 1. The filter element 1 is located between the two sleeves 6 at both ends of the drum 5.

[0037] The rotating drum 5 on the upper connecting seat 2 is rotated downward, driving the sleeve 6 and the slide rod 9 to move downward together until the limiting plate 16 contacts the lower surface of the upper connecting seat 2, and the rotating drum 5 is rotated 90 degrees.

[0038] Pull down the slide bars 9 at both ends of the sleeve 6 respectively, the slide bars 9 drive the connecting plates 8 at the ends to slide down together, and the connecting plates 8 will stretch the first spring 7 downward. At the same time, push the positioning rod 15 on the lower connecting seat 3, the positioning rod 15 slides on the fixing rod 13, so that the end of the positioning rod 15 leaves the supporting plate 11 and compresses the second spring 14.

[0039] Until the bottom end of the slide bar 9 contacts the lower connecting seat 3, the slide bar 9 slides to the side of the support plate 11 on the upper surface of the corresponding lower connecting seat 3. The positioning rod 15 is released, and the positioning rod 15 is pushed under the elastic force of the second spring 14. The end of the positioning rod 15 passes through the positioning hole 10 and is located in the support plate 11, and the slide bar 9 is fixed at this time.

[0040] Similarly, the filter element 1 can be installed by rotating the drum 5 on the lower connecting seat 3 upward and fixing the slide bar 9 on the drum 5 on the upper connecting seat 2 .

[0041] During disassembly, push the positioning rod 15 to make it leave the corresponding positioning hole 10, and pull the sliding rod 9 toward the inside of the sleeve 6 under the action of the elastic force of the first spring 7 to make the sliding rod 9 leave the corresponding support plate 11, so that the upper connecting seat 2 can be removed and the filter element 1 can be replaced.

[0042] When the upper connecting seat 2 is not in use, the sleeve 6 can be rotated to the lower surface of the upper connecting seat 2 for easy movement or storage.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
