Description

Technical Field

[0001] This utility model relates to the field of gas source treatment element technology, and in particular to a rotary dryer. Background Technology

[0002] In the field of pneumatic components, an air filter is an air source treatment element that filters and discharges moisture from compressed air. The reduced humidity of the processed compressed air prevents corrosion of the inner walls of pipes and valve cores in pneumatic control components. Currently, common air filters on the market mainly consist of a valve body, a cyclone blade assembly, a filter element, a water cup, and a drain. The valve body has an inlet and an outlet. Compressed air enters the valve body through the inlet, and after passing through the cyclone blade assembly, a cyclone airflow separates the oil and water in the compressed air. The separated oil and water are collected in the water cup and discharged through the drain. The dried compressed air is filtered by the filter element and discharged through the outlet. For the specific structure and working principle of air filters, please refer to the Chinese Utility Model Patent (Publication No.: CN207478209U) which discloses an air filter with water purification function, or the Chinese Invention Patent (Publication No.: CN103463875A) which discloses a pulse-type drain air filter.

[0003] The shortcomings of existing air filters are as follows: ① The valve core of existing air filters is often installed on the drain valve seat, integrating drainage and exhaust functions. However, in actual use, the compressed air entering the filter often contains not only moisture and oil, but also some solid particles and ribbon-like objects. During operation, these solid particles and ribbon-like objects accumulate at the bottom of the water tank, causing the drain to become clogged. At this time, the drain cannot perform drainage and exhaust functions. When customers repair the air filter, they need to release the residual pressure in the air filter to ensure the safety of the repair process. However, a clogged drain cannot release the residual pressure in the air filter. ② The existing air filter uses a straight barrel connection between the valve body and the water storage cup, and the valve cavity of the valve body and the cup cavity of the water storage cup are connected. In actual use, the wind pressure generated by the rotation of the cyclone blades in the valve cavity will cause the oil and water collected in the water storage cup that has not been drained from the drain in time to splash up. The splashed oil and water are discharged from the air outlet with the airflow and enter the pneumatic equipment connected to the air outlet, causing the precision pneumatic equipment to be damaged by water and oil, and the air filter to lose its water filtering function.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art where the valve core of the air filter is often installed on the drain valve seat, which is inconvenient for customers to maintain, and the problem that the air filter loses its water filtration function due to the direct connection between the valve body and the water storage cup. Therefore, a rotary dryer is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rotary dryer includes a valve body, a valve cover, a water storage cup, a filter assembly, and a drainer. The valve cover is installed on the upper end of the valve body. The valve body has a valve cavity inside. The valve cover has an air inlet and an air outlet communicating with the valve cavity. The filter assembly is disposed in the valve cavity and fixedly connected to the valve cover. The drainer is disposed at the bottom of the water storage cup. A valve body mounting seat is fixedly connected to the lower end of the valve body. The valve body mounting seat has a first constriction portion. A cup body mounting seat is fixedly connected to the upper end of the water storage cup. The cup body mounting seat has a second constriction portion. The first constriction portion of the valve body mounting seat and the second constriction portion of the cup body mounting seat cooperate to form a narrow channel for fluid to pass through. A valve core assembly for exhaust is disposed on the cup body mounting seat.

[0008] Furthermore, the first constricted portion is configured with a larger upper port diameter and a smaller lower port diameter.

[0009] Furthermore, the second constricted portion is configured with a smaller upper port diameter and a larger lower port diameter.

[0010] Furthermore, a first sealing ring is provided between the valve body mounting seat and the valve body, and a second sealing ring is provided between the cup body mounting seat and the water storage cup.

[0011] Furthermore, the valve body mounting seat and the cup body mounting seat are screwed together through the first constriction portion and the second constriction portion, and a third sealing ring is provided between the valve body mounting seat and the cup body mounting seat.

[0012] Furthermore, the filter assembly includes a cyclone blade fixedly connected to the valve cover, a water filter bucket fixedly connected to the cyclone blade, a connecting seat fixedly installed inside the water filter bucket, and a connecting screw fixedly connected to the connecting seat. The other end of the connecting screw is fixedly connected to a baffle plate, which is positioned above the narrow channel.

[0013] Furthermore, the cup body mounting base is provided with a mounting hole that communicates with the interior of the water storage cup, and the valve core assembly is fixedly installed in the mounting hole.

[0014] Furthermore, the valve core assembly includes a mounting sleeve fixedly installed in the mounting hole, a valve stem movably installed in the mounting sleeve, a sealing plug fixedly installed at the lower end of the valve stem, and a pagoda spring sleeved on the valve stem. The pagoda spring abuts against the valve stem and the mounting sleeve, so that the valve stem always has an upward movement tendency, thereby driving the sealing plug to always have a movement tendency to block the mounting hole.

[0015] Furthermore, the valve stem is provided with a pressing part extending out of the mounting sleeve, the upper end of the valve stem is provided with a convex ring, the mounting sleeve is provided with an annular step, the upper end of the pagoda spring abuts against the convex ring, and the lower end of the pagoda spring abuts against the annular step.

[0016] Furthermore, a fourth sealing ring is provided between the valve core assembly and the mounting hole of the cup body mounting seat.

[0017] The beneficial effects of this utility model after adopting the above structure are as follows:

[0018] (1) The rotary dryer of the present invention includes a valve body, a valve cover, a water storage cup, a filter assembly and a drainer. The valve cover is installed on the upper end of the valve body. The valve body has a valve cavity inside. The valve cover has an air inlet and an air outlet that are respectively connected to the valve cavity. The filter assembly is disposed in the valve cavity and fixedly connected to the valve cover. The drainer is disposed at the bottom of the water storage cup. The lower end of the valve body is fixedly connected to a valve body mounting seat. The valve body mounting seat has a first constriction. The upper end of the water storage cup is fixedly connected to a cup body mounting seat. The cup body mounting seat has a second constriction. The first constriction of the valve body mounting seat and the second constriction of the cup body mounting seat cooperate to form a narrow channel for fluid to pass through. The cup body mounting seat is provided with a valve core assembly for exhaust. This invention features a narrow channel between the valve body and the water reservoir. This narrow channel effectively reduces the impact of wind pressure from the cyclone blades on the oil and water in the reservoir. Furthermore, the narrow channel significantly reduces oil and water splashing into the valve cavity. Most of the splashed oil and water is blocked by the second constriction of the reservoir's mounting base. This structural design further improves the drying effect of the dryer, providing dry and clean air for pneumatic equipment connected to the air outlet. This effectively ensures that precision equipment is not damaged by water or oil, guaranteeing the accuracy and lifespan of the pneumatic equipment.

[0019] (2) The rotary dryer of this utility model has a valve core assembly for exhaust on the cup body mounting base. When the customer needs to repair or maintain the dryer, the residual pressure in the dryer can be released by pressing the valve stem of the valve core assembly, ensuring the safety and convenience of the maintenance and repair process.

[0035] like Figures 1 to 5 As shown, a rotary dryer includes a valve body 1, a valve cover 2, a water storage cup 3, a filter assembly 4, and a drainer 5. The valve cover 2 is installed on the upper end of the valve body 1. The valve body 1 has a valve cavity 11 inside. The valve cover 2 has an air inlet 21 and an air outlet 22 that are respectively connected to the valve cavity 11. The filter assembly 4 is disposed in the valve cavity 11 and fixedly connected to the valve cover 2. The drainer 5 is disposed at the bottom of the water storage cup 3. The lower end of the valve body 1 is fixedly connected to a valve body mounting seat 6. The valve body mounting seat 6 has a first constriction portion 61. The upper end of the water storage cup 3 is fixedly connected to a cup body mounting seat 7. The cup body mounting seat 7 has a second constriction portion 71. The first constriction portion 61 of the valve body mounting seat 6 and the second constriction portion 71 of the cup body mounting seat 7 cooperate to form a narrow channel 611 for fluid to pass through. The cup body mounting seat 7 is provided with a valve core assembly 8 for exhaust. The first constricted portion 61 has a larger upper diameter and a smaller lower diameter. The second constricted portion 71 has a smaller upper diameter and a larger lower diameter. A first sealing ring 62 is provided between the valve body mounting seat 6 and the valve body 1, and a second sealing ring 72 is provided between the cup body mounting seat 7 and the water storage cup 3. The valve body mounting seat 6 and the cup body mounting seat 7 are screwed together through the first constricted portion 61 and the second constricted portion 71, and a third sealing ring 63 is provided between the valve body mounting seat 6 and the cup body mounting seat 7.

[0036] Based on the above embodiments, the present invention aims to provide a rotary dryer, including a valve body 1, a valve cover 2, a water storage cup 3, a filter assembly 4, and a drainer 5. The valve cover 2 is installed on the upper end of the valve body 1. The valve body 1 has a valve cavity 11 inside. The valve cover 2 has an air inlet 21 and an air outlet 22 that are respectively connected to the valve cavity 11. The filter assembly 4 is disposed in the valve cavity 11 and fixedly connected to the valve cover 2. The drainer 5 is disposed at the bottom of the water storage cup 3. The lower end of the valve body 1 is fixedly connected to a valve body mounting seat 6. The valve body mounting seat 6 has a first constriction portion 61. The upper end of the water storage cup 3 is fixedly connected to a cup body mounting seat 7. The cup body mounting seat 7 has a second constriction portion 71. The first constriction portion 61 of the valve body mounting seat 6 and the second constriction portion 71 of the cup body mounting seat 7 cooperate to form a narrow channel 611 for fluid to pass through. The cup body mounting seat 7 is provided with a valve core assembly 8 for exhaust. This invention features a narrow channel 611 between the valve body 1 and the water reservoir 3. This narrow channel 611 effectively reduces the impact of wind pressure from the cyclone blades 41 on the oil and water in the water reservoir 3. Furthermore, it significantly reduces oil and water splashing into the valve chamber 11 of the valve body 1. Most of the splashed oil and water is blocked by the second constriction 71 of the reservoir 7. This structural design further improves the drying effect of the dryer, providing dry and clean air for pneumatic equipment connected to the air outlet 22. This effectively ensures that precision equipment is not damaged by water or oil, guaranteeing the accuracy and lifespan of the pneumatic equipment. The reservoir 7 is equipped with a valve core assembly 8 for venting. When the customer needs to repair or maintain the dryer, pressing the valve stem 82 of the valve core assembly 8 will release the residual pressure in the dryer, ensuring a safe and convenient maintenance process.

[0037] In this embodiment, the narrow channel 611 greatly reduces the wind pressure brought by the cyclone blades 41 when it enters the water storage cup 3. The oil and water carried by the reduced wind pressure are further blocked when passing through the narrow channel 611. Most of the oil and water is blocked by the second constriction 71 of the cup body mounting seat 7, and the baffle plate 45 is placed above the narrow channel 611 to further block the splashing oil and water.

[0038] In this embodiment, the first sealing ring 62 improves the sealing performance between the valve body mounting seat 6 and the valve body 1, the second sealing ring 72 improves the sealing performance between the cup body mounting seat 7 and the water storage cup 3, and the third sealing ring 63 improves the sealing performance between the valve body mounting seat 6 and the cup body mounting seat 7. The first sealing ring 62, the second sealing ring 72, and the third sealing ring 63 improve the overall sealing performance of the dryer and enhance its operational reliability.

[0039] In this embodiment, a drainer 5 is provided. The drainer 5 is located at the bottom of the water storage cup 3. After the water and oil generated by filtration are collected at the bottom of the water storage cup 3, they are discharged through the drainer 5.

[0040] As another preferred embodiment of this utility model, the filter assembly 4 includes a cyclone blade 41 fixedly connected to the valve cover 2, a water filter bucket 42 fixedly connected to the cyclone blade 41, a connecting seat 43 fixedly disposed inside the water filter bucket 42, and a connecting screw 44 fixedly connected to the connecting seat 43. A baffle plate 45 is fixedly connected to the other end of the connecting screw 44, and the baffle plate 45 is disposed above the narrow channel 611. In this embodiment, as... Figure 2 As shown, compressed air enters the valve body 1 through the air inlet 21. Due to the strong rotation of the cyclone blades 41, the liquid oil, water and solid pollutants in the compressed air are thrown onto the side wall of the water filter bucket 42 by centrifugal force, and then drip down the wall of the water filter bucket 42, finally flowing to the bottom of the water storage cup 3. The dried compressed air is discharged through the air outlet 22 to provide a dry air source for pneumatic equipment.

[0041] In another preferred embodiment of this utility model, the cup mounting base 7 is provided with a mounting hole 73 communicating with the interior of the water storage cup 3, and the valve core assembly 8 is fixedly installed in the mounting hole 73. The valve core assembly 8 includes a mounting sleeve 81 fixedly installed in the mounting hole 73, a valve stem 82 movably disposed in the mounting sleeve 81, a sealing plug 83 fixedly disposed at the lower end of the valve stem 82, and a pagoda spring 84 sleeved on the valve stem 82. The pagoda spring 84 abuts against the valve stem 82 and the mounting sleeve 81, so that the valve stem 82 always has an upward movement tendency, thereby driving the sealing plug 83 to always have a movement tendency to block the mounting hole 73. The valve stem 82 is provided with a pressing part 821 extending out of the mounting sleeve 81, the upper end of the valve stem 82 is provided with a protruding ring 822, the mounting sleeve 81 is provided with an annular step 811, the upper end of the pagoda spring 84 abuts against the protruding ring 822, and the lower end of the pagoda spring 84 abuts against the annular step 811. A fourth sealing ring 85 is provided between the valve core assembly 8 and the mounting hole 73 of the cup body mounting seat 7. In this embodiment, as... Figure 4As shown, the upper end of the valve stem 82 is provided with a convex ring 822, and the mounting sleeve 81 is provided with an annular step 811. The upper end of the pagoda spring 84 abuts against the convex ring 822, and the lower end of the pagoda spring 84 abuts against the annular step 811. The pagoda spring 84 causes the valve stem 82 to move upward, thereby driving the sealing plug 83 to seal the mounting hole 73. Manual venting is achieved through the valve stem 82, the mounting sleeve 81, and the pagoda spring 84. During manual venting, the pressing part 821 presses the valve stem 82 downward, causing the valve stem 82 to move downward against the elastic force of the pagoda spring 84, thereby driving the sealing plug 83 to move downward and release the seal on the mounting hole 73. At this time, the residual pressure in the dryer can be discharged from the mounting hole 73, thus completing the manual venting. After manual venting is completed, the pressure on valve stem 82 is released. Under the elastic force of the pagoda spring 84, valve stem 82 moves upward, thereby causing the sealing plug 83 to move upward, sealing the mounting hole 73. In this embodiment, the fourth sealing ring 85 improves the sealing performance between the valve core assembly 8 and the cup mounting seat 7.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
