Description

Technical Field

[0001] This utility model relates to the field of compressed air preparation technology, specifically to a dryer adsorption tower with different adsorbents filled in the upper and lower sections. Background Technology

[0002] The adsorption tower of a dryer is a core device that achieves deep drying by selectively adsorbing water vapor in compressed air using adsorbents (such as activated alumina and molecular sieves) packed inside. The purpose of filling different adsorbents in the upper and lower sections is to optimize adsorption efficiency and extend service life. Typically, it is filled with activated alumina, which has high mechanical strength and large moisture capacity, and molecular sieves, which have high adsorption precision. Activated alumina is used to initially remove most of the moisture, while molecular sieves are responsible for deep removal of residual water molecules, thereby achieving gradient adsorption and balancing drying effect with economy.

[0003] However, traditional segmented packing dryer adsorption towers are prone to pulverization of the adsorbent under the pressure impact of frequent switching. The resulting fine particles easily clog the filter, requiring manual shutdown and periodic replacement of the clogged filter element. However, the replacement process is often time-consuming and labor-intensive, forcing extended downtime of production equipment and easily causing a loss of production efficiency. Therefore, a dryer adsorption tower with different adsorbents packed in the upper and lower sections is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a dryer adsorption tower with different adsorbents packed in upper and lower sections. It features the advantage of automatic filter replacement, solving the problem of traditional segmented dryer adsorption towers requiring manual shutdown for filter replacement due to adsorbent pulverization and clogging, leading to production interruptions and low efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dryer adsorption tower with different adsorbents filled in the upper and lower sections, comprising a tower body, an air inlet pipe connected to the bottom of the tower body, an air outlet pipe connected to the top of the tower body, an opening on the right side of the air outlet pipe, and a storage component provided at the opening.

[0006] The storage component includes a storage compartment fixedly connected to the opening of the air outlet pipe. An annular slide rail is fixedly installed between the storage compartment and the inner wall of the air outlet pipe. Four sliding blocks are slidably connected inside the annular slide rail. A connecting rod is fixedly installed on the outer wall of each of the four sliding blocks. A support plate is fixedly installed on the opposite side of each of the four connecting rods away from the four sliding blocks. Two filters are provided at the bottom of the support plate. A motor is fixedly installed on the top of the tower body. A rotating shaft is fixedly installed on the output end of the motor. The end of the rotating shaft away from the motor is fixedly connected to the bottom of the support plate. Four grooves are formed inside the support plate. Two small springs are fixedly installed on the top wall of each of the four grooves. Clamping blocks are fixedly installed at the bottom of each of the eight small springs.

[0007] Furthermore, the support plate has a number of ventilation holes inside, and all of the ventilation holes are located above the filter.

[0008] Furthermore, each pair of clamping blocks is hinged to each other, and two locking blocks are fixedly installed on the top of the filter, with each locking block positioned between the two clamping blocks.

[0009] Furthermore, a groove is provided at the bottom of the storage compartment, and a number of support springs are fixedly installed on the bottom wall of the groove, with the tops of the support springs all in contact with the bottom of the filter on the right side.

[0010] Furthermore, an annular support plate is fixedly installed on the inner wall of the air outlet pipe, and a No. 1 sealing ring is fixedly installed on the top of the annular support plate. The top of the No. 1 sealing ring is in contact with the bottom of the left filter.

[0011] Furthermore, a hole is provided at the bottom of the storage compartment, through which the rotating shaft extends into the interior of the storage compartment. A second sealing ring is fixedly installed at the bottom of the hole, and the inner wall of the second sealing ring is in contact with the surface of the rotating shaft.

[0012] Furthermore, a doorway is provided on the right side of the storage compartment, and a protective door is hinged to the doorway. A sealing layer is provided on the surface of the protective door, and the top and bottom of the sealing layer are in contact with the inner wall of the storage compartment.

[0013] Furthermore, a partition plate is fixedly installed on the inner wall of the tower, and a number of breathing holes are opened inside the partition plate.

[0014] Compared with the prior art, this utility model provides a dryer adsorption tower with different adsorbents filled in the upper and lower sections, which has the following beneficial effects:

[0015] 1. This dryer adsorption tower, which is divided into upper and lower sections and filled with different adsorbents, allows for rapid replacement of filters on one side when the filter needs to be replaced. The motor drives the rotating shaft to rotate the support plate on the annular slide rail, rotating the clogged filter into the storage compartment and simultaneously rotating the spare new filter into the working position of the air outlet pipe. This design enables rapid replacement without stopping the machine through rotational switching, ensuring the continuity of the drying process and thus extending the overall working time.

[0016] 2. In this dryer adsorption tower with different adsorbents in upper and lower sections, after both filters have been used, the operator opens the protective door, presses down on the filter to squeeze the support spring, and causes the clip at the top of the filter to disengage from the clamping block, allowing the old filter to be removed. Then, the new filter is placed in the storage chamber, the support spring is pressed down again, and the filter is pushed up until the clip at the top is automatically clamped and fixed by the hinged clamping block under the action of the small spring, thus quickly completing the replacement of the dual filters. This design extends the service life of each filter by having the two filters alternately perform the filtration task, eliminating the need for frequent replacements and significantly reducing downtime caused by maintenance, thereby improving overall work efficiency.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 In this embodiment, a dryer adsorption tower with different adsorbents filled in the upper and lower sections includes a tower body 1, an air inlet pipe 2 connected to the bottom of the tower body 1, an air outlet pipe 3 connected to the top of the tower body 1, an opening on the right side of the air outlet pipe 3, and a storage component 4 provided at the opening.

[0025] Specifically, the storage component 4 includes a storage compartment 5 fixedly connected to the opening of the air outlet pipe 3. An annular slide rail 6 is fixedly installed on the inner wall of the storage compartment 5 and the air outlet pipe 3. Four sliding blocks are slidably connected inside the annular slide rail 6. Connecting rods 7 are fixedly installed on the outer walls of the four sliding blocks. A support plate 8 is fixedly installed on the opposite side of the four connecting rods 7 away from the four sliding blocks. Two filters 13 are provided at the bottom of the support plate 8. A motor 9 is fixedly installed on the top of the tower body 1. A rotating shaft 10 is fixedly installed at the output end of the motor 9. The end of the rotating shaft 10 away from the motor 9 is fixedly connected to the bottom of the support plate 8. Four grooves are opened inside the support plate 8. Two small springs 11 are fixedly installed on the top walls of the four grooves. Clamping blocks 12 are fixedly installed at the bottom of the eight small springs 11.

[0026] When it is necessary to replace the clogged filter 13, the motor 9 is started to drive the rotating shaft 10 to rotate the support plate 8. The support plate 8 rotates smoothly in the annular slide rail 6 through the connecting rod 7 and the sliding block, thereby turning the spare filter 13 in the storage compartment 5 into the working position.

[0027] Specifically, the support plate 8 has a number of ventilation holes inside, and the ventilation holes are all located above the filter 13.

[0028] When the dry gas flows through the outlet pipe 3, it first passes upward through the working filter 13 for final filtration, then reaches and passes through the vent, and is then smoothly discharged from the system, thus ensuring the smooth flow path.

[0029] Please see Figure 2 In this embodiment, every two clamping blocks 12 are hinged to each other, and two locking blocks 14 are fixedly installed on the top of the filter 13, with each locking block 14 being disposed between the two clamping blocks 12.

[0030] Please see Figure 3In this embodiment, a groove is provided at the bottom of the storage compartment 5, and a number of support springs 15 are fixedly installed on the bottom wall of the groove. The top of the support springs 15 are all in contact with the bottom of the right filter 13.

[0031] The filter 13 is secured by a pair of hinged clamps 12 under the pressure of a small spring 11. Meanwhile, the spare filter 13 stored in the storage compartment 5 is supported upward by a support spring 15 at its bottom. This allows the operator to press down on the filter 13 to compress the support spring 15 when it needs to be replaced, thereby disengaging the clamp 14 from between the clamps 12 and allowing the filter 13 to be removed or installed.

[0032] Please see Figure 3 In this embodiment, an annular support plate is fixedly installed on the inner wall of the air outlet pipe 3, and a No. 1 sealing ring is fixedly installed on the top of the annular support plate. The top of the No. 1 sealing ring is in contact with the bottom of the left filter 13.

[0033] When the filter 13 is rotated to the working position, its bottom will press against the No. 1 sealing ring to form a sealing barrier. This ensures that all dry gas from the tower body 1 must pass completely through the filter 13 for filtration when entering the outlet pipe 3, without leaking from the edge of the filter 13, thus guaranteeing the filtration effect.

[0034] It should be noted that the annular support plate also provides stable support for the filter 13, ensuring its stability during operation.

[0035] Please see Figure 3 In this embodiment, a hole is provided at the bottom of the storage compartment 5, and the rotating shaft 10 extends into the interior of the storage compartment 5 through the hole. A second sealing ring is fixedly installed at the bottom of the hole, and the inner wall of the second sealing ring is in contact with the surface of the rotating shaft 10.

[0036] Among them, the No. 2 sealing ring effectively seals the gap between the rotating shaft 10 and the hole, preventing the dry gas in the outlet pipe 3 from leaking into the atmosphere through the gap, thus ensuring the airtightness of the entire system.

[0037] Please see Figure 3 In this embodiment, a doorway is provided on the right side of the storage compartment 5, and a protective door 16 is hinged at the doorway. A sealing layer is provided on the surface of the protective door 16, and the top and bottom of the sealing layer are in contact with the inner wall of the storage compartment 5.

[0038] When it is necessary to replace the clogged filter 13, the operator can open this protective door 16 to remove the old filter 13 from the storage compartment 5 and install the new filter 13.

[0039] When the protective door 16 is closed, the sealing layer, through its elastic deformation, fits tightly against the inner wall of the storage chamber 5, forming a reliable airtight barrier that effectively prevents the leakage of dry gas in the exhaust pipe 3, while also blocking external moisture and pollutants from entering the storage chamber 5.

[0040] Please see Figure 1 In this embodiment, a partition plate 17 is fixedly installed on the inner wall of the tower body 1. The partition plate 17 has a number of breathing holes. A filter screen 18 is provided above the partition plate 17. A deep drying layer is provided on the top of the filter screen 18. A main drying layer is provided at the bottom of the partition plate 17. A shut-off valve 19 is fixedly installed on the surface of the air outlet pipe 3.

[0041] The humid gas enters the tower body 1 through the inlet pipe 2, first undergoes preliminary dehumidification through the main drying layer, then flows upward through the breathing hole, and is filtered and deeply dried through the filter screen 18 and the deep drying layer in sequence. Finally, the dried gas is discharged through the outlet pipe 3.

[0042] It should be noted that the shut-off valve 19 is used to cut off the airflow to ensure operational safety when maintenance or replacement of the filter 13 is required.

[0043] The working principle of the above embodiments is as follows:

[0044] Moist gas is introduced through the intake pipe 2, and after initial dehumidification by the main drying layer, it enters the upper part through the vent of the partition plate 17. It then passes through the filter screen 18 and the deep drying layer for further purification. The dried gas then enters the exhaust pipe 3, passes through the filter 13, and is discharged after passing through the vent on the support plate 8.

[0045] When one filter 13 becomes clogged and needs replacement, first close the shut-off valve 19, then start the motor 9 to drive the rotating shaft 10 to rotate the support plate 8 along the annular slide rail 6, turning the clogged filter 13 into the storage compartment 5. At the same time, screw the spare filter 13 in the storage compartment 5 into the working position. When both filters 13 become clogged after long-term use, the operator opens the protective door 16 and presses down on the two filters 13 respectively to compress the support spring 15, so that the locking block 14 on the top of each filter 13 disengages from the pair of hinged clamping blocks 12, and the old filter 13 can be removed. Then, put the two new filters 13 into the storage compartment 5 and press down on the support spring 15 again, and then push the filter 13 upward until its top locking block 14 is automatically clamped and fixed by the hinged clamping block 12 under the action of the small spring 11, thus quickly completing the replacement of the two filters 13.

[0046] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
