Description

Technical Field

[0001] This utility model relates to the field of drying filter technology, and in particular to a drying filter that facilitates the replacement of molecular sieves. Background Technology

[0002] A dryer filter is a type of filter commonly used in various industrial equipment to remove moisture and impurities from air, gas, or liquid. Molecular sieves are usually used to remove moisture and impurities from gases or liquids to prevent moisture from damaging equipment or systems. After prolonged use, molecular sieves need to be replaced.

[0003] Currently, there are various types of molecular sieve dryer filters on the market, but these devices are not convenient for replacing molecular sieves, resulting in slow replacement speeds. Furthermore, the replaced molecular sieve particles are not easy to remove for cleaning, which to some extent affects the work efficiency of the staff. Utility Model Content

[0004] This invention addresses the problem that some devices on the market are inconvenient for replacing molecular sieves, resulting in slow replacement speeds and difficulties in removing and cleaning the replaced molecular sieve particles, which to some extent affects the work efficiency of the staff. Therefore, it provides a dry filter that facilitates the replacement of molecular sieves.

[0005] This utility model is achieved by the following technical solution: a dry filter that facilitates the replacement of molecular sieves, including a dry filter body, a molecular sieve body that is slidably connected inside the dry filter body, a fixing block that is fixedly connected to the front and rear ends on one side of the molecular sieve body, an auxiliary mechanism that is fixedly connected inside the dry filter body, a self-locking mechanism that is installed at both the front and rear ends on the other side of the molecular sieve body, and a flip-top mechanism that is installed at the rear end of the molecular sieve body.

[0006] Using the above technical solution, the molecular sieve body can be pulled out entirely by pulling the self-locking mechanism inward and then pulling it outward. The auxiliary mechanism is used to further fix the molecular sieve body. Then, the flip-top mechanism can be pulled outward to open the door, thereby replacing the internal molecular sieve.

[0007] As a further improvement to the above solution, the dryer filter body includes a housing, with an air inlet fixedly connected to the top of the housing and an air outlet fixedly connected to the bottom of the housing.

[0008] Using the above technical solution, the gas enters the interior of the dryer filter body through the air inlet, then passes through the molecular sieve body, and finally exits from the air outlet.

[0009] As a further improvement to the above solution, the molecular sieve body includes a shell that is slidably connected inside the dryer filter body. Filter screens are fixedly installed on the top and bottom of the shell, and rectangular grooves are provided at the front and rear ends of the shell on the side away from the auxiliary mechanism.

[0010] The above technical solution involves placing molecular sieve particles between the two filter screens.

[0011] As a further improvement to the above solution, the auxiliary mechanism includes multiple limiting blocks fixedly connected inside the housing. Each of the multiple limiting blocks has a spring fixedly connected inside it, and the other end of each of the multiple springs has a ball fixedly connected to it. Each of the multiple balls abuts against the outer surface of the fixing block.

[0012] With the above technical solution, the sphere is used to limit the fixed block, and most of the area of ​​the sphere is inside the limiting block.

[0013] As a further improvement to the above solution, the self-locking mechanism includes a slider 1 that is slidably connected inside the rectangular groove, a cylinder 1 that is slidably connected to the rear end of the slider 1, the other end of the cylinder 1 that is fixedly connected to the rear end of the rectangular groove, a spring 2 that is sleeved on the outer surface of the cylinder 1, a pull plate that is fixedly connected to the side of the slider 1 away from the auxiliary mechanism, and a main body that is fixedly connected to the side of the housing away from the auxiliary mechanism.

[0014] Using the above technical solution, by pressing the pull plates inside the two main bodies, cylinder one will gradually slide into the interior of slider one, and then pull the main body outward, thereby smoothly pulling out the entire molecular sieve body.

[0015] As a further improvement to the above solution, the pull plate is slidably connected inside the main body, and the two self-locking mechanisms are symmetrically installed on one side of the housing.

[0016] As a further improvement to the above solution, the flip-top mechanism includes a long plate rotatably connected to one side of the rear end of the housing. An arc-shaped plate is slidably connected inside the long plate on the side near the self-locking mechanism. A slider two is slidably connected inside the long plate on the side near the self-locking mechanism. A cylinder two is slidably connected on the other side of the slider two. A spring three is sleeved on the outer surface of the cylinder two.

[0017] Using the above technical solution, pulling the arc plate inside the long plate will cause the arc plate to slide to one side along with the slider two. The cylinder two will gradually slide into the interior of the slider two. At this time, the spring three on the cylinder two will be compressed inward and contract. Then, the arc plate will be pulled outward to open the long plate, thereby replacing and cleaning the molecular sieve particles inside.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes the cooperation of an auxiliary mechanism and a self-locking mechanism. First, the pull plates inside the two main bodies are pressed inward simultaneously. Then, the pull plates drive the slider one to move inward, and the cylinder one gradually slides into the interior of the slider one. At this time, the spring two on the cylinder one will be compressed inward and contract. Then, the main body is pulled outward, and the main body will drive the entire molecular sieve body to move outward together. The fixing block on the molecular sieve body will also move outward. The ball inside the limiting block will be compressed and move inward, thereby causing the spring one connected to the ball to contract, thus allowing the fixing block to disengage from the limiting position and smoothly pulling out the entire molecular sieve body. During installation, simply push the entire molecular sieve body into the dryer filter body to complete the self-locking, further accelerating the efficiency of replacing the molecular sieve body.

[0020] This invention features a flip-top mechanism that pulls the arc-shaped plate inside the long plate. The arc-shaped plate, along with the slider two, slides to one side, causing the cylinder two to gradually slide into the slider two's interior. At this point, the spring three on the cylinder two contracts under inward pressure. Then, the arc-shaped plate is pulled outward, opening the long plate and allowing for the replacement and cleaning of the internal molecular sieve particles. After the cleaned molecular sieve particles are installed, simply pushing the flipped-out long plate into the molecular sieve body completes the self-locking process, further accelerating work efficiency and improving practical effectiveness.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5 This embodiment of a dryer filter that facilitates the replacement of molecular sieves includes a dryer filter body 1, a molecular sieve body 2 that is slidably connected inside the dryer filter body 1, a fixing block 3 that is fixedly connected to the front and rear ends on one side of the molecular sieve body 2, an auxiliary mechanism 4 that is fixedly connected inside the dryer filter body 1, a self-locking mechanism 5 that is installed at both the front and rear ends on the other side of the molecular sieve body 2, and a flip-top mechanism 6 that is installed at the rear end of the molecular sieve body 2.

[0032] The dryer filter body 1 includes a housing 11, with an air inlet 12 fixedly connected to the top of the housing 11 and an air outlet 13 fixedly connected to the bottom of the housing 11.

[0033] The molecular sieve body 2 includes a housing 21 that is slidably connected inside the dryer filter body 1. Filter screens 22 are fixedly installed on the top and bottom of the housing 21. Rectangular grooves 23 are provided at the front and rear ends of the housing 21 on the side away from the auxiliary mechanism 4.

[0034] The auxiliary mechanism 4 includes multiple limiting blocks 41 fixedly connected inside the housing 11. Each of the multiple limiting blocks 41 has a spring 42 fixedly connected inside. Each of the other ends of the multiple springs 42 has a ball 43 fixedly connected to it. Each of the multiple balls 43 abuts against the outer surface of the fixing block 3.

[0035] The self-locking mechanism 5 includes a slider 51 that is slidably connected inside the rectangular groove 23. A cylinder 52 is slidably connected to the rear end of the slider 51. The other end of the cylinder 52 is fixedly connected to the rear end of the rectangular groove 23. A spring 53 is sleeved on the outer surface of the cylinder 52. A pull plate 54 is fixedly connected to the side of the slider 51 away from the auxiliary mechanism 4. A main body 55 is fixedly connected to the side of the housing 21 away from the auxiliary mechanism 4.

[0036] The pull plate 54 is slidably connected inside the main body 55, and two self-locking mechanisms 5 are symmetrically installed on one side of the housing 21.

[0037] The flip-top mechanism 6 includes a long plate 61 rotatably connected to one side of the rear end of the housing 21. An arc-shaped plate 62 is slidably connected inside the long plate 61 near the self-locking mechanism 5. A slider 63 is slidably connected inside the long plate 61 near the self-locking mechanism 5. A cylinder 64 is slidably connected to the other side of the slider 63. A spring 65 is sleeved on the outer surface of the cylinder 64.

[0038] The implementation principle of a dryer filter that facilitates molecular sieve replacement in this embodiment is as follows: Gas enters the dryer filter body 1 through the inlet 12, then passes through the molecular sieve body 2, and finally exits from the outlet 13. When the molecular sieve body 2 needs to be replaced, the operator needs to press the pull plates 54 inside the two main bodies 55 simultaneously. The pull plates 54 will then drive the slider 51 to move inward together, and the cylinder 52 will gradually slide into the inside of the slider 51. At this time, the spring 53 on the cylinder 52 will be compressed inward. Then the operator pulls the main body outward. 55. The main body 55 will move the entire molecular sieve body 2 outward together. At this time, the fixing block 3 on the molecular sieve body 2 will also move outward. The ball 43 inside the limiting block 41 will be squeezed and move inward, thereby causing the spring 42 connected to the ball 43 to contract, so that the fixing block 3 can be released from the limiting position, and the entire molecular sieve body 2 can be pulled out smoothly. After the entire molecular sieve body 2 is pulled out, the operator needs to pull the arc plate 62 inside the long plate 61 again by hand. At this time, the arc plate 62 will slide to one side with the slider 63. The cylinder 64 will gradually slide into the inside of the slider 63. Spring 65 on column 2 64 will contract under inward pressure, and then the arc plate 62 will be pulled outward, thereby opening the long plate 61 to replace and clean the molecular sieve particles inside. After replacement and cleaning, the operator only needs to push the flipped-out long plate 61 into the molecular sieve body 2. When rotating inward, slider 2 63 will gradually contract under the pressure of the molecular sieve body 2. When placed inside the molecular sieve body 2, slider 2 63 will enter the groove inside the molecular sieve body 2 and then extend out again, thus achieving a limiting effect. Then the entire molecular sieve body 2 is pushed... As the molecular sieve body 2 enters the dryer filter body 1, the sliders 51 on both sides will be squeezed and gradually contract inward. Finally, when the entire molecular sieve body 2 enters the interior of the dryer filter body 1, the sliders 51 will enter the groove inside the dryer filter body 1, so that the sliders 51 will extend out again to achieve the limiting effect. The ball 43 in the auxiliary mechanism 4 will also touch the fixing block 3 and contract inward. Then, the two balls 43 will clamp the fixing blocks 3 respectively, thereby achieving the effect of auxiliary fixation, thus completing the cleaning of the molecular sieve body 2, further improving work efficiency and enhancing the actual effect.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
