[0002] The air contains dust particles and various suspended matter, especially in windy weather, the wind can carry dust and suspended matter into the room. With the development of science and technology, people's requirements for air cleanliness are getting higher and higher, and the demand for air filtration using air filters is gradually expanding.

[0003] The outer frame of the partitionless filter is beautiful. Under the same air volume conditions, compared with the high-efficiency filter with partitions, it has the advantages of small size, light weight, compact structure, reliable performance, etc. The partitionless filter generally includes a filter element and an outer frame to fix the filter element. Under high-temperature filtration conditions, the sealant at the seal of the filter element will melt and fall off, resulting in gaps and causing damage to the filter element. Not only can it not meet the filtration requirements, but it also requires frequent replacement of the filter element. In addition, dust will adhere to the surface of the filter element, resulting in poor ventilation effect. For this reason, the present invention proposes a high-temperature resistant partitionless filter that can solve the above problems. Summary of the invention

An insert block is fixedly connected to the top of the lining rod, and the adjusting rod penetrates into the shell and is connected to a pressure plate. The pressure plate is used to limit the lining rod. By continuously rotating the adjusting rod toward the outside of the shell, the lining rod can be pivoted under the elastic force of the elastic stretching member to drive the insert block to be inserted into the slot.

[0017] As a preferred technical solution of the present invention, a ball bearing is installed at the bottom of the liner rod, and a plurality of groups of annular protrusions are arranged at intervals on the pressure plate, so that when the movable block drives the frame to move up and down, the liner rod drives the plug block to collide with the slot to generate vibration.

[0023] The frame can be connected to the movable block through a connecting component so that the movable block can drive the frame to shake off the dust attached to the filter element when it moves up and down. The dust can be discharged through the structural drainage component to avoid a decrease in ventilation volume when filtering air;

[0024] When the frame moves up and down, the ball rolls vertically through several groups of protrusions, causing the lining rod to reciprocate at a small angle, driving the plug block to collide with the slot to generate vibration, so that the dust attached to the filter element can be further removed under the action of vibration, effectively ensuring that the filter element maintains an efficient ventilation effect.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figure 1-8 The present invention provides a technical solution: a high temperature resistant partition-free filter, comprising a housing 100, a filter mechanism 200, a movable block 300 and a power mechanism 400.

[0037] See also Figure 1 , Figure 2 The shell 100 is provided with an air inlet 110 and an air outlet 120 and is provided with an air intake assembly through which air can be sucked. The outside of the shell 100 is provided with a heat insulating layer made of heat insulating materials such as glass fiber wool boards to reduce heat transfer into the shell 100.

[0038] See also Figure 2 , Figure 4The filtering mechanism 200 includes a frame 210 and a filter element 220. The frame 210 is arranged in the housing 100 through a support rod 230. The filter element 220 is located at the middle opening of the frame 210 and is bonded to the side groove of the outer ring of the opening. A drainage component 240 is arranged on the front side of the opening of the frame 210. The drainage component 240 is connected to the air inlet 110. The frame 210 is sleeved on the support rod 230. The filter element 220 is installed at the opening of the frame 210 and is bonded to the side groove of the frame 210 through a sealant, so that there is no gap between the filter element 220 and the frame 210. The frame 210 is made of a metal material that is heat-conductive, and the drainage component 240 can guide the incoming air.

[0039] See also Figure 3 , Figure 8 The movable block 300 is sleeved on the support rod 230, and an air ring 310 is arranged at the bottom of the movable block 300. The air outlet of the air ring 310 is provided with an exhaust bypass pipe 320 through an air pipe 311. The exhaust bypass pipe 320 is provided with multiple groups of air holes 321 aligned with the outer wall of the frame 210. The air pipe is a hose. The exhaust bypass pipe 320 is fixedly arranged in the shell 100. The air ring 310 has a built-in elastic support ring. After being compressed by force, the internal gas can be transported to the exhaust bypass pipe 320 through the air pipe 311 and blown onto the frame 210 through the air holes 321 for heat dissipation, thereby cooling the sealant, so that the sealant at the connection of the filter element 220 can maintain its original state under a long-term high-temperature working environment, and there is no need to frequently replace the filter element 220.

[0040] See also Figure 2 , Figure 4 , Figure 6 The power mechanism 400 includes a power source 410 installed in the shell 100. The power source 410 can drive the movable block 300 to move up and down through the driving component 420 to compress the air ring 310 and quickly exhaust the gas to dissipate the heat of the frame 210. The frame 210 can be connected to the movable block 300 through the connecting component 430 so that when the movable block 300 moves up and down, it drives the frame 210 to shake off the dust attached to the filter element 220. The power source 410 is preferably a servo motor. When filtering the air, the power source 410 can drive the movable block 300 to move downward through the driving component 420 so that the air ring 310 contacts the frame 210 to compress and exhaust. When the movable block 300 moves upward, it can drive the air ring 310 to leave so that the air ring 310 resumes automatic air intake. When the air filtering stops, the frame 210 can be connected to the movable block 300 through the connecting component 430 so that the frame 210 shakes off the dust attached to the filter element 220. The dust can be discharged through the structure guide component 240 to avoid a decrease in ventilation volume when filtering the air.

[0041] When filtering air, the air intake component draws external air into the shell 100 from the air inlet 110. The air is filtered through the filter element 220 along the guide component 240 and then discharged from the air outlet 120. The power source 410 drives the movable block 300 to move up and down through the driving component 420. The compressed air ring 310 quickly discharges gas to dissipate heat from the frame 210 and cool the sealant, so that the sealant at the connection of the filter element 220 can maintain its original state in a long-term high-temperature working environment. When the air filtering stops, the frame 210 can be connected to the movable block 300 through the connecting component 430 to allow the frame 210 to shake off the dust attached to the filter element 220. The dust can be discharged through the guide component 240 to avoid a decrease in ventilation volume when filtering air.

[0042] Example 2

[0043] See also Figure 2 , Figure 8 On the basis of Example 1, the air ring 310 can be elastically restored after compression and air can be taken in through the air inlet nozzle. The air inlet nozzle can take in air in one direction. The air inlet nozzle is connected to an atomizer through an air inlet pipe 312. The air inlet pipe 312 is a hose. The air inlet assembly includes an air suction source 130 installed on the rear side of the frame 210 and a grid 140 arranged on the air outlet 120. The grid 140 can adjust the air outlet angle up and down. The air suction source 130 is preferably a fan. The air outlet end of the air suction source 130 extends to the air outlet 120. The atomizer can generate a mixed gas of water mist and air, so that the mixed gas discharged from the air hole 321 contains water mist after contacting the frame 210, which can absorb heat and evaporate, thereby further improving the cooling effect on the sealant. The air outlet angle of the filtered air is adjusted by the grid 140, which has good practicality.

[0044] See also Figure 6 A stopper 231 is provided on the support rod 230, and the stopper 231 is used to limit the lowest position of the frame 210 on the support rod 230. An elastic traction member 232 is provided in the shell 100, and the elastic traction member 232 extends upward and is connected to the frame 210. The elastic traction member 232 is preferably a spring.

[0045] See also Figure 5 The driving assembly 420 includes a driving column 421 connected to the power output end, and a movable rod 422 is sleeved on the driving column 421. The movable rod 422 extends downward and is hinged to the movable block 300.

[0046] See also Figure 2 , Figure 3The drainage component 240 includes a cover body 241 and an annular belt 242. The diameter of the cover body 241 gradually shrinks from one end to the other end along the center line. The annular belt 242 is a continuous elastic belt. One end of the annular belt 242 is connected to the frame 210, and the other end is connected to the end of the cover body 241 with a smaller diameter. The end of the cover body 241 with a larger opening is connected to the air inlet 110. The inner and outer sides of the annular belt 242 are coated with an airtight layer, which separates the shell 100 into an air inlet cavity and an air outlet cavity in an airtight manner. When filtering air, The cover body 241 and the annular belt 242 form an air guide channel, so that the external air can directly connect to the filter element 220 through the air guide channel under the traction of the suction source 130, and the filtering effect is good. The annular belt 242 is coated with a water-based airtight coating to form an isolation, so that the dust contained in the air will not adhere to the power source 410 and other components. The annular belt 242 is an elastic structure that can be stretched when subjected to force; when the air filtering stops, the dust shaken off the filter element 220 can be smoothly discharged through the cover body 241 that gradually expands from the inside to the outside.

[0047] Example 3

[0048] See also Figure 3 , Figure 4 , Figure 6 , Figure 7 On the basis of Example 1 or Example 2, the connecting assembly 430 includes a slot 431 opened on the movable block 300, a lining rod 432 hinged on the frame 210, an adjusting rod 433 screwed on the shell 100, and an elastic stretching member 434 connected to the lining rod 432 and the frame 210, a plug block 4321 is fixed to the top of the lining rod 432, the adjusting rod 433 penetrates into the shell 100 and is connected to a pressing plate 4331, and the pressing plate 4331 is used to limit the lining rod 432, and the lining rod 432 can be moved in the elastic stretching member 434 by continuously rotating the adjusting rod 433 toward the outside of the shell 100. Under the action of the elastic force of 34, the plug block 4321 is pivoted and inserted into the slot 431. The elastic stretching member 434 is preferably a spring, which has the tendency to drive the lining rod 432 to rotate counterclockwise. When the adjusting rod 433 drives the pressure plate 4331 to move outward, the lining rod 432 can drive the adjusting rod 433 to rotate and the plug block 4321 is inserted into the slot 431, so that the movable block 300 and the frame 210 form a connection relationship. The movable block 300 can drive the frame 210 to move up and down along the support rod 230. At the same time, when the movable block 300 drives the frame 210 to move, the air ring 310 no longer reciprocates and compresses and recovers.

[0049] See also Figure 3 , Figure 4 , Figure 6 , Figure 7A ball 4322 is installed at the bottom of the lining rod 432, and a plurality of groups of annular protrusions 4332 are arranged at intervals on the pressure plate 4331, so that when the movable block 300 drives the frame 210 to move up and down, the lining rod 432 drives the plug block 4321 to collide with the slot 431 to generate vibration, and the ball 4322 contacts the pressure plate 4331. When the frame 210 moves up and down, the ball 4322 rolls vertically through the plurality of protrusions, so that the lining rod 432 reciprocates at a small angle to drive the plug block 4321 to collide with the slot 431 to generate vibration, so that the dust attached to the filter element 220 can be further fallen off under the action of vibration, effectively ensuring that the filter element 220 maintains a high-efficiency ventilation effect.

[0053] S2, the power source 410 drives the movable block 300 to move up and down through the driving assembly 420, and the compressed air ring 310 quickly discharges gas to dissipate heat from the frame 210, which has a cooling effect on the sealant, so that the sealant at the connection of the filter element 220 can maintain its original state under a long-term high-temperature working environment;

[0054] S3, the air intake assembly stops sucking air, and the frame 210 is connected to the movable block 300 through the connecting assembly 430 so that the frame 210 can shake off the dust attached to the filter element 220.
