Description

Technical Field

[0001] The invention relates to the technical field of double-barrel filters, in particular to a double-barrel filter with an inner wall that is convenient to clean. Background Art

[0002] In the prior art, for some media that need to be recycled, such as oil, the oil will contain impurities in the process of recycling, so it is necessary to use a filter to filter the impurities contained in the medium. During the filtering, the filter element in the filter is used to filter the impurities. The filter element is replaced after its service life has reached. At the same time, in order to effectively avoid the replacement time of the filter element being too long and affecting the recycling of the medium, the current filter is usually a double-barrel structure. The double-barrel structure allows one of the filter elements to filter while the other filter element is prepared. Therefore, when one of the filter elements needs to be replaced, the medium is filtered by the other filter element, thereby improving the filtering efficiency. However, during the use of the current filter, some impurities will adhere to the inner wall of the filter cylinder. Since the filter is generally large in size, it is not convenient to clean its inner wall. Based on this, the present application proposes a double-barrel filter that is easy to clean the inner wall, which can achieve efficient cleaning of the inner wall of the filter cylinder;

[0033] The beneficial effects of the present invention are:

[0034] 1. The vertical rod and the conical scraper can be fixed by means of a buckle connection by providing a buckle plate and a buckle frame. The conical scraper can be used to scrape and clean the impurities attached to the inner wall of the cylinder.

When the inclined block moves along the inclined surface of the inclined groove, the lower blocking plate can be expanded and tightened to ensure the sealing between the filter part and the joint part.

[0037] 4. When one end of the three-way cleaning pipe and one end of the lower blocking plate are connected, the two push rods squeeze the sealing plate and the extension plate respectively during the interlacing process, so that the three-way cleaning pipe and the cleaning connecting pipe can be connected, thereby ensuring that the cleaning liquid in the three-way cleaning pipe can enter the cleaning connecting pipe and finally be sprayed out through the nozzle, so as to flush the inner wall of the cylinder circumference.

[0038] 5. By providing a support plate, the area where one end of the cleaning pipe and the cylinder are in contact can be temporarily blocked during the filtering process of the medium, thereby preventing the medium from entering the cleaning pipe and interfering with the nozzle, thereby ensuring the safety of the medium during the filtering process.

[0055] Embodiment 1:

[0057] Rectangular plates 12: two rectangular plates 12 are fixed to the top outer wall of the base 1 by bolts, and a same limiting rod 9 is fixed between the two rectangular plates 12 by pins;

[0058] Slider 20: It is slidably connected to the outer wall of the limit rod 9, and the inner walls of the through holes opened on both sides of the slider 20 are slidably connected to the T-shaped rods 18;

[0059] Spring 19: It is sleeved on the outer circumferential wall of the T-shaped rod 18, and the two ends of the spring 19 are respectively fixed to the inner wall of one side of the slider 20 and the inner wall of one side of the T-shaped rod 18 by pins;

[0060] The lateral receiving plate 14 is fixed to one end of the T-shaped rod 18 by a pin;

[0061] Cylinder 39: It is fixed to the inner wall of the through hole opened on the surface of the lateral accommodating plate 14 by embedding, and the bottom and side wall of the cylinder 39 are respectively welded with a clamping plate 2 51 and a cleaning pipe 17;

[0062] The abutment ring 37 is welded to the inner wall of the cylinder 39, and a bump 38 is welded on the top of the abutment ring 37;

[0063] The clamping plate 16 has a slot at its bottom adapted to the protrusion 38, and the outer diameter of the clamping plate 16 and the inner diameter of the cylinder 39 are adapted to each other;

[0064] Adsorption groove 47: It is opened on the side wall of the card receiving plate 16;

[0065] Threaded disc 54: It is welded to the bottom of the clamping disc 16 through the connecting rod 48, and the bottom of the threaded disc 54 is connected to the filter element 53 through threads;

[0066] Support frame 7: It is fixed to the top outer wall of the base 1 by pins, and the inner wall of the through hole opened on the surface of the support frame 7 is embedded with a three-way cleaning pipe 4;

[0067] Trapezoidal plate 36: It is welded to the outer wall of one side of the slider 20 through the connecting column 11;

[0068] Vertical plate 8: It is fixed to the top outer wall of the base 1 by pins, and the inner wall of the through hole opened at the top of the vertical plate 8 is slidably connected with a rectangular rod 34, and an extension plate 32 is welded to the top outer wall of the rectangular rod 34, and an electromagnetic sheet 31 is fixed to the outer wall of one side of the extension plate 32 by pins;

[0069] The toggle frame 33 is welded to the bottom of the rectangular rod 34, and the inner wall of the toggle frame 33 is rotatably connected with a roller 35;

[0070] The cleaning unit comprises:

[0071] The vertical rod 49 is fixed to the bottom of the clamping plate 16 by a pin, and a buckle frame 56 is welded to the bottom of the vertical rod 49, and a buckle plate 55 is rotatably connected to the inner wall of the buckle frame 56, and a torsion spring is provided between the buckle plate 55 and the buckle frame 56;

[0072] Conical scraper 50 : A retaining plate 52 is welded on its inner surface, and a retaining hole matching the outer diameter of the buckle plate 55 is opened on the surface of the retaining plate 52 .

[0073] By connecting the joint part and the filter part, the medium to be filtered can be introduced into the filter part through the joint part for filtering; by providing a snap-in disk 16, the medium can be introduced into the cylinder 39; the cylinder 39 can support the top of the snap-in disk 16; the protrusion 38 and the slot provided at the bottom of the snap-in disk 16 can realize rapid positioning between the snap-in disk 16 and the cylinder 39, so that the adsorption groove 47 provided on the side wall of the snap-in disk 16 can face the notch provided on the side of the cylinder 39; by threading the filter element 53 and the snap-in disk 16, the filter element 53 can be quickly disassembled and replaced after its service life has expired; during the filtering process, the medium enters the cylinder 39 through the snap-in disk 16, and is finally discharged through the bottom of the snap-in disk 51 after filtering the impurities through the filter element 53.

[0074] In the present embodiment, the number of cylinders 39 is preferably two groups. The double-cylinder structure allows one of the cylinders 39 to be docked with the joint part using the clamping plate 1 16 and the clamping plate 2 51, and the other cylinder 39 can play a preparatory role. When the filter element 53 in the cylinder 39 docked with the joint part reaches the end of its service life, the prepared cylinder 39 can be replaced. By setting a limit rod 9, the two cylinders 39 can move horizontally. The two cylinders 39 can pass through the joint part respectively during the movement, and the cylinders that need to be docked can be easily replaced by the lateral movement. The cylinder 39 is quickly moved to the joint part for docking. When the prepared cylinder 39 and the joint part are docked, the cylinder 39 that needs to replace the filter element 53 gradually approaches one end of the three-way cleaning pipe 4 during the sliding process along the limit rod 9. When the cleaning connection pipe 17 on the cylinder 39 moves to fit the three-way cleaning pipe 4, the three-way cleaning pipe 4 and the pump body are connected at this time. The pump body can be used to pressurize the cleaning liquid and then introduce it into the cleaning connection pipe 17 through the three-way cleaning pipe 4, and finally enter the cylinder 39 to clean the inner wall of the cylinder 39.

[0075] When the cylinder 39 whose inner wall needs to be cleaned moves toward one end of the three-way cleaning pipe 4, the adsorption groove 47 opened on the side wall of the clamping plate 16 will gradually approach the electromagnetic sheet 31. When the electromagnetic sheet 31 enters the adsorption groove 47, the magnetic force of the electromagnetic sheet 31 can be adsorbed on the inner wall of the adsorption groove 47, thereby fixing the clamping plate 16. When the cleaning pipe 17 and one end of the three-way cleaning pipe 4 are fitted, when the slider 20 continues to slide along the outer wall of the limit rod 9, the three-way cleaning pipe 4 limits one end of the cleaning pipe 17. The spring 19 is elastically deformed during this process, so that after the cleaning pipe 17 is limited by the three-way cleaning pipe 4, the slider 20 can continue to drive the connecting column 11 and the trapezoidal plate 36 to move horizontally. Since one side of the trapezoidal plate 36 is an inclined structure, the trapezoidal plate 36 pushes the roller 35 during the movement, so that the roller 35 can roll along the inclined structure of the side direction of the trapezoidal plate 36 during the movement of the trapezoidal plate 36. The roller 35 can drive the electromagnetic sheet 31 to lift the card plate 16 during the gradual rise, so that the card plate 16 can be clamped. The disk 16 can drive the filter element 53 to be removed from the cylinder 39, so as to facilitate the replacement of the filter element 53. The clamping disk 16 can drive the conical scraper 50 to slide along the inner wall of the cylinder 39 by using the hanging rod 49 during the lifting process. The conical scraper 50 scrapes the impurities attached to the inner wall of the cylinder 39 during the movement. The scraped impurities fall into the conical scraper 50 for collection. An annular partition is provided in the middle of the conical scraper 50 to prevent the scraped impurities from overflowing. By setting the buckle plate 55 to rotate along the buckle frame 56, when it is needed, To connect the vertical rod 49 and the conical scraper 50, the snap-on plate 55 can be rotated inward along the snap-on frame 56, and then the locking plate 52 can be slid up along the bottom of the vertical rod 49 through the snap-on hole, so that after the conical scraper 50 moves to the top of the snap-on plate 55, the elastic force of the torsion spring is used to support the conical scraper 50 from the bottom of the conical scraper 50. In this way, after impurities are collected in the conical scraper 50, the conical scraper 50 can be removed from the snap-on plate 55, thereby facilitating the cleaning of the conical scraper 50.

[0076] Furthermore, the joint portion includes an L-shaped plate 3 and an arc-shaped joint 6, the L-shaped plate 3 is fixed to the top outer wall of the base 1 by bolts, and the two arc-shaped joints 6 are respectively fixed to the inner walls of the through holes opened at the top of the support frame 7 and the inner walls of the through holes opened at the top of the L-shaped plate 3 by embedding, and a telescopic bellows 25 is embedded at one end of the arc-shaped joint 6, and a lower blocking plate 27 is fixed at one end of the telescopic bellows 25 away from the arc-shaped joint 6, and a same spring three 29 is fixed between the outer wall on one side of the lower blocking plate 27 and the outer wall on one side of the arc-shaped joint 6 by a pin.

[0077] In this embodiment, there are two joint parts, which can be connected with the clamping disk 1 16 and the clamping disk 2 51 on the same cylinder 39 respectively. When connecting, the straight-line distance between the lower plugging plate 27 and the arc joint 6 is adjusted by compressing the spring three 29. The telescopic bellows 25 is retractable. When the clamping disk 1 16 and the clamping disk 2 51 are moved to the ends of the two lower plugging plates 27 respectively, the rebound force of the spring three 29 is used to make the two lower plugging plates 27 quickly connected with the clamping disk 1 16 and the clamping disk 2 51 by clamping. A valve is fixed at one end of the arc joint 6. The valve can be used to temporarily seal the medium in the arc joint 6 when the filter element 53 needs to be replaced.

[0078] Furthermore, a guide plate 26 is welded to the circumferential outer wall of the lower blocking plate 27, and an oblique groove 28 is opened on the surface of the guide plate 26. The outer wall of the slider 20 is fixed with an expansion plate 5 by bolts. The two expansion plates 5 on the same side are fixedly connected by a U-shaped frame 2, and an oblique block 30 adapted to the oblique groove 28 is fixed to the outer wall of the expansion plate 5 by pins.

[0079] By fixing the expansion plate 5 and the slider 20, the expansion plate 5 can move synchronously with the slider 20. In this embodiment, the number of expansion plates 5 is four, and two expansion plates 5 form a group. A trapezoidal plate is integrally formed on the top of the expansion plate 5. When the expansion plate 5 slides along the bottom of the guide plate 26, when the trapezoidal plate moves to the bottom of the guide plate 26, the inclined surface position of the trapezoidal plate will push the bottom of the guide plate 26, so that the guide plate 26 can drive the two lower blocking plates 27 to move a certain distance, which is convenient for the clamping plate 16 and the The clamping plate 2 51 can be docked with the two lower blocking plates 27. When the trapezoidal plate is completely detached from the bottom of the guide plate 26, the lower blocking plate 27 is reset under the action of the rebound force of the spring 3 29. At the same time, when the expansion plate 5 continues to move, the inclined block 30 gradually fits with the surface of the inclined groove 28. The inclined block 30 continuously applies pressure to the surface of the inclined groove 28 during the movement, so that the two lower blocking plates 27 and the clamping plate 1 16 and the clamping plate 2 51 are continuously expanded and tightened, thereby ensuring the sealing between the two lower blocking plates 27 and the clamping plate 1 16 and the clamping plate 2 51.

[0080] Furthermore, a blocking plate 10 adapted to the lateral accommodating plate 14 is fixed to the top outer wall of the base 1 by bolts.

[0081] By providing a blocking plate 10, the maximum distance that the lateral accommodating plate 14 can move can be limited. When the lateral accommodating plate 14 moves to fit the surface of the blocking plate 10, the cylinder 39 can ensure that it is in a facing position with the lower blocking plate 27, thereby ensuring that the two lower blocking plates 27 can be accurately docked with the clamping disk 16 and the clamping disk 2 51.

[0082] Furthermore, a hole plate 24 is welded to the inner wall of the end of the three-way cleaning pipe 4, a spring 21 is clamped at one end of the hole plate 24, and a sealing plate 22 is clamped at one end of the spring 21 away from the hole plate 24.

[0083] By utilizing the elastic force of the second spring 21 , the sealing plate 1 22 can seal one end of the three-way cleaning pipe 4 in the initial state, thereby preventing the cleaning liquid in the three-way cleaning pipe 4 from overflowing.

[0084] Furthermore, a hole plate 42 is welded to the inner wall of the circumference of the cleaning connecting pipe 17, a spring 45 is clamped on the outer wall of one side of the hole plate 42, and a sealing plate 43 is clamped on the end of the spring 45 away from the hole plate 42, a lining rod 44 is welded to the inner wall of one side of the sealing plate 43, and a support plate 40 is fixed to one end of the lining rod 44 by a pin, an insert plate 46 is welded to the outer wall of one side of the support plate 40, and a nozzle 41 is embedded in the through hole opened in the surface of the insert plate 46, and the nozzle 41 and the hole plate 42 are connected by a hose, and one end of the cleaning connecting pipe 17 and one end of the three-way cleaning pipe 4 are both connected to a push rod 23 by threads.

[0085] When the three-way cleaning pipe 4 and the cleaning pipe 17 are connected, the push rod 23 at one end of the cleaning pipe 17 passes through the through hole opened at one end of the three-way cleaning pipe 4 during the movement and pushes the sealing plate 22, so that a relative opening is generated between the sealing plate 22 and the end of the three-way cleaning pipe 4. At the same time, the push rod 23 at one end of the three-way cleaning pipe 4 passes through the through hole opened at one end of the cleaning pipe 17 during the movement and pushes the sealing plate 243, thereby achieving conduction between the cleaning pipe 17 and the three-way cleaning pipe 4. During this process, the support plate 40 can be pushed by the lining rod 44, so that the support plate 40 protrudes a distance relative to the inner wall of the cylinder 39, and then the nozzle 41 is extended into the cylinder 39. The cleaning liquid can be sprayed by the nozzle 41, so that the inner wall of the cylinder 39 is cleaned twice by flushing. By providing the support plate 40, one end of the cleaning pipe 17 can be temporarily closed after it is reset, so as to avoid the medium entering the cleaning pipe 17 during the filtration process and interfering with the nozzle 41.

[0086] Furthermore, a driving motor 13 is fixed to an outer wall of one side of the rectangular plate 12 by bolts, a threaded rod 15 is rotatably connected between the two rectangular plates 12, and the threaded rod 15 and an output end of the driving motor 13 are connected by a coupling.

[0087] The drive motor 13 can be provided to drive the threaded rod 15 to rotate, so that the slider 20 can move in the lateral direction under the guidance of the limiting rod 9 .

[0088] When the present embodiment is in use, when it is necessary to filter impurities in the medium, the filter element 53 is first connected to the bottom of the threaded disk 54 through the thread, and then the clamping disk 16 is placed on the abutment ring 37, and the protrusion 38 is used to position the clamping disk 16 and the abutment ring 37, and then the drive motor 13 is started, and the drive motor 13 is used to drive the T-bar 18 to rotate, so that the slider 20 drives the two cylinders 39 to move synchronously in the horizontal direction under the guidance of the limit rod 9. During this process, one of the cylinders 39 is close to the three-way cleaning pipe 4, and the other cylinder 39 gradually moves toward the two joints. During the movement, the cylinder 39 uses the expansion The trapezoidal plate on the expansion plate 5 can play a role in pushing up the bottom of the guide plate 26, so that the two lower blocking plates 27 move a certain distance. When the cylinder 39 that needs to be connected to the joint part moves to the blocking plate 10, the blocking plate 10 can be used to limit the cylinder 39. With the continuous movement of the expansion plate 5, when the trapezoidal plate on the expansion plate 5 is separated from the bottom of the guide plate 26, the rebound force of the spring three 29 is used to make the two lower blocking plates 27 respectively clamped on the clamping disk 1 16 and the clamping disk 2 51. With the continued movement of the expansion plate 5, the inclined block 30 gradually moves to the inclined groove 28, and the inclined block 30 is used to tighten the lower blocking plate 27.

[0089] At the same time, another cylinder 39 close to the three-way cleaning pipe 4, when the cleaning pipe 17 on the side wall of the cylinder 39 is fitted with one end of the three-way cleaning pipe 4, as the slider 20 continues to move, the trapezoidal plate 36 can guide the roller 35, and the roller 35 rolls along the inclined part of the trapezoidal plate 36 under the push of the trapezoidal plate 36, so that the electromagnetic plate 31 can lift the clamping disk 16 after being inserted into the inner wall of the adsorption groove 47, and the clamping disk 16 can drive the filter element 53 to gradually rise from the cylinder 39 after rising. In this process, the conical scraper 50 can be used to clean the impurities on the inner wall of the circumference of the cylinder 39 by scraping. After scraping, the three-way cleaning pipe 4 is used to introduce cleaning liquid into the cleaning pipe 17, and the cleaning liquid can be used to rinse the inner wall of the cylinder 39, thereby ensuring the cleaning effect.

[0090] Embodiment 2:

[0091] A double-tube filter that is easy to clean the inner wall, such as Fig.13As shown, in order to improve the cleaning effect; this embodiment makes the following supplements on the basis of embodiment 1: the outer wall of the conical scraper 50 is provided with an inner shrinkage hole 57, and a rubber scraper 58 is bonded to the bottom of the conical scraper 50, and a leak hole 64 is provided at the bottom of the conical scraper 50, an annular scraper 61 is inserted into the inner wall of the circumference of the conical scraper 50, and a clamping block 59 adapted to the clamping plate 52 is fixed to the inner wall of the circumference of the annular scraper 61 by screws, and an inner shrinkage hole 2 60 adapted to the inner diameter of the inner shrinkage hole 57 is provided on the outer wall of the circumference of the annular scraper 61, and the inner shrinkage hole 2 60 and the inner shrinkage hole 57 are staggered, a sealing piece 63 is welded to the inner wall of the circumference of the annular scraper 61, and a scraper 62 is welded to the upper surface of the sealing piece 63, and a top scraper 65 is welded to the top of the annular scraper 61;

[0092] By providing a rubber scraper 58, when the conical scraper 50 moves up in the vertical direction to scrape impurities from the inner wall of the cylinder 39, the rubber scraper 58 has a certain degree of flexibility in nature, which can ensure the fit between the rubber scraper 58 and the inner wall of the cylinder 39, thereby ensuring that the rubber scraper 58 can complete the cleaning of impurities during the movement. The outer diameter of the conical scraper 50 is slightly larger than the inner diameter of the cylinder 39. By providing an inner shrinkage hole 57 on the outer wall of the circumference of the conical scraper 50, when the conical scraper 50 slides along the inner wall of the cylinder 39, the conical scraper 50 can be squeezed by the cylinder 39. The conical scraper 50 can be squeezed inward to a certain extent through the inner shrinkage hole 57. This can ensure that the outer wall of the conical scraper 50 and the inner wall of the cylinder 39 fit closely, thereby improving the effect of the conical scraper 50 on cleaning impurities from the inner wall of the cylinder 39.

[0093] At the same time, an annular scraper 61 is installed on the inner wall of the conical scraper 50 by insertion, so that when the positioning block 59 and the positioning plate 52 are aligned, the vertical rod 49 plays a limiting role between the annular scraper 61 and the conical scraper 50, so as to avoid the annular scraper 61 from being deflected relative to the conical scraper 50. At the same time, the inner shrinkage hole 60 and the inner shrinkage hole 1 57 are staggered, so that the outer wall of the conical scraper 50 can be enclosed into a complete annular structure. Since the conical scraper 50 has a certain thickness, the top scraper 65 can be provided to temporarily block the notch at the top of the inner shrinkage hole 1 57 after the annular scraper 61 is inserted into the inner wall of the conical scraper 50. After installation, the bottom height of the top scraper 65 is higher than the top height of the conical scraper 50. The sealing piece 63 can be provided to seal the bottom of the leakage hole 64, thereby preventing impurities from overflowing during the process of scraping impurities by the conical scraper 50. When it is necessary to clean the impurities collected in the conical scraper 50, the annular scraper 61 and the conical scraper 50 are removed from the vertical rod 49, and the annular scraper 61 is rotated along the conical scraper 50, so that the scraper 62 can continuously squeeze and push the impurities in the conical scraper 50 during the rotation process. At the same time, the sealing piece 63 and the leakage hole 64 are staggered with each other, so that the squeezed and pushed impurities can be discharged through the leakage hole 64.

[0094] The above is a preferred specific embodiment of the present invention, but it is not the only specific embodiment of the present invention. Any modification, equivalent substitution and improvement made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with the existing technology or public common sense within the spirit and principle of the present invention should be covered by the protection scope of the present invention.
