Description

Technical Field

[0001] The present invention relates to the technical field of drying equipment, and specifically, to a drying device for preparing a high-porosity honeycomb catalyst. Background Art

[0002] The high-porosity honeycomb catalyst block is a new type of catalyst block, which has characteristics such as a high specific surface area, a high porosity, and a high stability. The noble metal honeycomb catalyst block with platinum and palladium as active components can play a good purification role in the treatment of Vocs waste gas.

[0003] Generally, it is made through multiple processes such as mixing, pre-extrusion, extrusion molding, primary and secondary drying, and calcination. Among them, after extrusion molding, it needs to be dried. The prior art generally uses a drying oven for drying.

[0004] For example, in the patent document with the publication number CN115900271B in the prior art, a drying device for preparing a high-porosity honeycomb catalyst includes a drying chamber for placing catalyst blocks. A support plate and a porous partition are provided in the drying chamber. The catalyst blocks are placed between the partition and the top of the drying chamber. The support plate is located below the partition. An air duct for inputting drying hot air into the drying chamber is provided on the support plate. An air chamber is formed between the support plate and the partition. The drying hot air first enters the air chamber and then passes upward through the partition. An active block driven by a lead screw motor is also provided between the partition and the top of the drying chamber. The lead screw motor includes a motor body, a lead screw, and a limiting rod. The active block reciprocates vertically in the drying chamber to form a disturbance to the catalyst blocks. The active block is threadedly connected to the lead screw, and the limiting rod is slidably connected to the active block. The active block is spherical, the active block is hollow, and a self-locking air nozzle is provided at both the top and the bottom of the active block. A plurality of columnar air bags communicating with the inside of the active block are provided on the outer wall of the active block. An air inlet pipe communicating with a gas source is provided on the partition, and an air outlet pipe communicating with the outside is provided on the top of the drying chamber. The air inlet pipe, the air outlet pipe, and the air nozzle are all on the same axis. When the air outlet pipe or the air inlet pipe is inserted into the air nozzle, the air nozzle is in an open state.

[0005] Its basic principle is to use a lead screw motor to drive the active block to perform linear reciprocating motion, which can realize the change of the position of the catalyst blocks in the drying chamber, so that each catalyst block will be in a state of intermittently moving away from or approaching the air outlet end of the air duct, thereby realizing the uniform drying of several catalyst blocks. The drying hot air moving from bottom to top realizes the drying effect on the catalyst blocks, increasing the contact area between the drying hot air and the catalyst blocks and improving the drying efficiency.

[0006] After studying the existing technology, especially the above-mentioned technical scheme, it is found that the catalyst block is disturbed, which is easy to cause damage to the catalyst block because the catalyst block has just been extruded, and the airbag is not very realistic during use, which is easy to cause wear and tear. The main thing is that the drying hot air only flows on the surface of the catalyst block, and its drying efficiency needs to be further improved. Summary of the invention

[0007] The main inventive concept of the present invention is as follows: without disturbing the catalyst block, the inner and outer sides of the catalyst block are dried simultaneously, thereby further improving the drying efficiency. During the drying process, in order to ensure the accurate position of the catalyst block, the catalyst block is transported by a positioning and conveying mechanism. At the same time, when the lifting and drying mechanism descends, the position of the catalyst block is further accurately determined by an elastic linkage mechanism, thereby facilitating the drying of the inside of the catalyst block. This can reduce the damage to the catalyst block in the above-mentioned prior art and further improve the drying efficiency.

[0008] To this end, the present invention adopts the following technical solution: a drying device for preparing high-porous honeycomb catalysts, including a device frame, a cover body is provided on the upper part of the device frame, and is characterized in that a positioning and conveying mechanism is provided on the device frame, a lifting and drying mechanism is provided inside the cover body, and a reflux cover body arranged on the device frame also includes an elastic linkage mechanism arranged on the lifting and drying mechanism, and a sliding door mechanism connected to the lifting and drying mechanism and slidingly arranged on both sides of the cover body.

[0009] By adopting the above technical scheme: the cover body and the reflux cover body can basically form a sealed cover body, and the surface of the catalyst block can be dried by the injected dry hot air, and the lifting and drying mechanism can be lifted and lowered. During the rising process, the sliding door mechanism can be opened in a linkage manner. The dried catalyst block is separated from the cover body by the positioning and conveying mechanism, and the catalyst block to be dried enters the inside of the cover body. At this time, the lifting and drying mechanism descends while driving the sliding door mechanism to gradually close the cover body, and at the same time, the position of the catalyst block can be further adjusted through the elastic linkage mechanism, so that the lifting and drying mechanism can partially enter the inside of the catalyst block, realizing simultaneous drying of the inside and the outside, which can reduce damage to the catalyst block and further improve the drying efficiency.

[0010] As a further optimization and improvement of the technical solution, the positioning and conveying mechanism includes a conveying component and a guide and positioning component arranged on the conveying component.

[0011] By adopting the above technical solution: the conveying component is mainly used to support and transport the catalyst block, and the guiding and positioning component is used to position the catalyst block. By cooperating with the elastic linkage mechanism, the catalyst block can be positioned more accurately, making it easier for the lifting and drying mechanism to enter the interior of the catalyst block for drying.

[0012] As a further optimization and improvement of the present technical solution, the conveying assembly includes a driving chain shaft and a driven chain shaft. A servo motor is drivingly connected to the driving chain shaft. A conveying chain plate is drivingly connected between the driving chain shaft and the driven chain shaft. The guiding and positioning assembly is arranged on the conveying chain plate.

[0013] By adopting the above technical solution: The servo motor can drive the driving chain shaft to rotate, thereby driving the conveying chain plate to rotate in a cycle for conveying the catalyst blocks. The servo motor is convenient to control. The guiding and positioning assembly cooperating with the elastic linkage mechanism can better control the position of the catalyst blocks, facilitating the internal and external drying of the catalyst blocks.

[0014] As a further optimization and improvement of the present technical solution, the guiding and positioning assembly includes a positioning groove arranged on the conveying chain plate and guiding inclined plates arranged on both sides of the front end of the positioning groove. The two guiding inclined plates incline towards the outside of the positioning groove.

[0015] By adopting the above technical solution: When conveying the catalyst blocks, the guiding inclined plates can basically guide the catalyst blocks into the positioning groove. Driven by the elastic linkage mechanism, the catalyst blocks can be accurately fixed inside the positioning groove, facilitating the drying mechanism part to enter the inside of the catalyst blocks for drying.

[0016] As a further optimization and improvement of the present technical solution, the lifting and drying mechanism includes a telescopic power member arranged on the top wall of the cover body. The cover body is of a cuboid structure. Wedge-shaped guide rails are arranged at the four corner positions of the cover body. The telescopic shaft of the telescopic power member extends into the cover body and is connected to a gas distribution component. The gas distribution component is communicated with an interface pipe arranged on the top wall of the cover body through a hose.

[0017] By adopting the above technical solution: The telescopic power member can drive the gas distribution component to move up and down inside the cover body, thereby realizing the opening or closing of the sliding door mechanism and the movement of the elastic linkage mechanism.

[0018] As a further optimization and improvement of the present technical solution, the gas distribution component includes a gas distribution cavity plate connected to the telescopic shaft. Wedge-shaped grooves are arranged at the four corner positions of the gas distribution cavity plate. The wedge-shaped grooves are slidably fitted on the wedge-shaped guide rails. A plurality of gas needles are communicated with the lower side of the gas distribution cavity plate. A plurality of air dispersion holes are arranged on each gas needle. The elastic linkage mechanism is arranged on the lower side of the gas distribution cavity plate.

[0019] By adopting the above technical solution: The air distribution cavity plate is connected to the telescopic shaft of the telescopic power member and can move up and down. Through the cooperation of the wedge-shaped groove and the wedge-shaped guide rail, the air distribution cavity plate can be better positioned to move up and down precisely. Specifically, when moving upward, it can drive the sliding door mechanism to open, enabling the catalyst block to enter and exit the cover body. When it descends, it can drive the elastic linkage mechanism to act first, pushing the catalyst block into the positioning groove. Continuing to descend, the air needle can be inserted into the holes in the catalyst block. Since the air distribution cavity plate is connected to the dry hot air through a hose and an interface pipe, the dry hot air can be discharged through the air dispersion holes to dry the inside of the catalyst block, improving the drying efficiency.

[0020] As a further optimization and improvement of this technical solution, the air needles are arranged in an array, and each group of array air needles is used to dry a high-hole honeycomb catalyst block. An elastic linkage mechanism is provided beside each group of array air needles.

[0021] By adopting the above technical solution: The air needles in each group can be targeted at a catalyst block and can be inserted into the holes in the catalyst block to dry the inside of the catalyst block.

[0022] As a further optimization and improvement of this technical solution, the elastic linkage mechanism includes a telescopic member arranged on the air distribution cavity plate. A touch plate is provided at the lower part of the telescopic member, and a slope pushing portion is provided on the side of the touch plate facing the guiding inclined plate.

[0023] By adopting the above technical solution: When the catalyst block enters the inside of the cover body, the telescopic power member drives the air distribution cavity plate to gradually move downward, driving the sliding door mechanism to gradually close the cover body, and at the same time driving the touch plate to move downward. Since the touch plate has a slope pushing portion, it gradually pushes the catalyst block completely into the positioning groove during the downward movement to complete the positioning. Since an elastic member is provided, after the catalyst block is pushed in place, the air distribution cavity plate can continue to compress the elastic member and move downward, without hindering the air needle from entering the holes in the catalyst block.

[0024] As a further optimization and improvement of this technical solution, the telescopic member includes a perforated plate connected to the lower side of the air distribution cavity plate. The upper end of the touch plate is slidably connected inside the perforated plate, and a first spring is provided between the touch plate and the perforated plate.

[0025] By adopting the above technical solution: The touch plate is arranged inside the perforated plate. When the lower end of the touch plate touches the conveyor chain plate, the telescopic power member can continue to drive the air distribution cavity plate to move downward. At this time, the first spring contracts and does not block the downward movement of the air distribution cavity plate.

[0026] As a further optimization and improvement of the present technical solution, the telescopic member includes a fixing plate connected to the lower side of the air distribution chamber plate. The touch plate is slidably connected to the fixing plate. An expansion rod is provided between the lower side of the air distribution chamber plate and the upper end of the touch plate. A second spring is sleeved on the outer peripheral side of the expansion rod, and the outer peripheral side of the second spring does not exceed the side of the touch plate facing the guiding inclined plate.

[0027] By adopting the above technical solution: There may be a connecting convex portion between the touch plate and the perforated plate, which may scratch the catalyst block. Therefore, this technical solution adopts the method of the second spring and the expansion rod, and the outer peripheral side of the second spring does not exceed the side of the touch plate facing the guiding inclined plate. So there is no connecting convex, avoiding scratching and damage to the peripheral side of the catalyst block.

[0028] As a further optimization and improvement of the present technical solution, a T-shaped chute is provided on the fixing plate, and a T-shaped slider is provided on the touch plate. The T-shaped slider slides inside the T-shaped chute.

[0029] By adopting the above technical solution: It can make the touch plate slide relative to the fixing plate.

[0030] As a further optimization and improvement of the present technical solution, the sliding door mechanism includes a strip groove provided on the cover body. Connecting rods are provided on both sides of the air distribution chamber plate and slide inside the strip groove. The outer ends of the connecting rods are connected with a sliding door.

[0031] By adopting the above technical solution: When the air distribution chamber plate moves up and down, the sliding door can be driven to move up and down through the connecting rods, thereby realizing the intermittent opening and closing of the sliding door.

[0032] As a further optimization and improvement of the present technical solution, a return pipe is connected to the lower part of the return cover body.

[0033] By adopting the above technical solution: Through the return pipe and the suction device, the dried hot air can be returned to form a hot air flow cycle. While accelerating drying, the dried hot air can be recycled.

[0034] The working principle and beneficial effects of the present invention are as follows: 1. The cover body and the reflux cover body in the present invention can basically form a sealed cover body, and the surface of the catalyst block can be dried by injecting dry hot air. The lifting and drying mechanism can be lifted and lowered. During the lifting process, the sliding door mechanism can be opened in a linkage manner. The dried catalyst block is separated from the cover body by the positioning and conveying mechanism, and the catalyst block to be dried enters the cover body. At this time, the lifting and drying mechanism descends while driving the sliding door mechanism to gradually close the cover body. At the same time, the position of the catalyst block can be further adjusted through the elastic linkage mechanism, which is convenient for the lifting and drying mechanism to partially enter the interior of the catalyst block, realizing simultaneous drying of the inside and the outside, which can reduce damage to the catalyst block and further improve the drying efficiency.

[0035] 2. In the present invention, the air chamber plate is connected to the telescopic shaft of the telescopic power part and can move up and down. The air chamber plate can be better positioned through the cooperation of the wedge-shaped groove and the wedge-shaped guide rail, so that it can move up and down accurately. Specifically, when moving upward, it can drive the sliding door mechanism to open, so that the catalyst block can enter and exit the cover body. When it descends, it can pre-drive the elastic linkage mechanism to move, first push the catalyst block into the positioning groove, and continue to descend. The air needle can be inserted into the hole in the catalyst block. Since the air chamber plate is connected to dry hot air through a hose and an interface pipe, the dry hot air can be discharged through the air diffusion hole to dry the catalyst block internally, thereby improving the drying efficiency.

[0036] 3. When the catalyst block enters the interior of the cover, the telescopic power part drives the air cavity plate to move downward gradually, drives the sliding door mechanism to gradually close the cover, and drives the touch plate to move downward at the same time. Since the touch plate has an inclined pushing part, the catalyst block is gradually pushed into the positioning groove in the process of moving downward to complete the positioning. Since an elastic part is provided, after the catalyst block is pushed into place, the air cavity plate can continue to compress the elastic part to move downward, and does not hinder the gas needle from entering the hole of the catalyst block.

[0037] 4. The drying hot air can be refluxed through the reflux pipe and suction equipment to form a hot air flow circulation, which can accelerate the drying and recycle the drying hot air. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0041] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0042] The present invention includes two specific embodiments. Of course, it is not limited to the limitations of the following specific embodiments. The main idea lies in the inventive concept of the present invention. The main inventive concept of the whole of the present invention is as follows: Without disturbing the catalyst block, the inner and outer sides of the catalyst block are dried simultaneously, further improving the drying efficiency. When drying, to ensure the position of the catalyst block, the catalyst block is conveyed through the positioning and conveying mechanism. At the same time, when the lifting and drying mechanism descends, the position of the catalyst block is further accurately positioned through the elastic linkage mechanism, facilitating the drying of the inside of the catalyst block. In this way, the damage to the catalyst block in the above-mentioned prior art can be reduced, and at the same time, the drying efficiency is further improved.

[0043] To this end, the present invention specifically provides the following two embodiments, and the two embodiments are as follows: Embodiment 1: Referring to Figures 1-7 , a drying device for preparing a high-porosity honeycomb catalyst proposed in this embodiment includes a device frame body 100. The device frame body 100 bears the entire device and can be welded from steel materials. A cover body 200 is provided on the upper part of the device frame body 100. A positioning and conveying mechanism 300 is provided on the device frame body 100 for conveying catalyst blocks. An elevating drying mechanism 400 is provided inside the cover body 200. It also includes a reflux cover body 500 provided on the lower side of the device frame body 100. The reflux cover body 500 corresponds to the cover body 200 and basically forms a sealed space for refluxing hot drying air. This embodiment also includes an elastic linkage mechanism 600 provided on the elevating drying mechanism 400, and a sliding door mechanism 700 that is connected to the elevating drying mechanism 400 and slides on both sides of the cover body 200.

[0044] The basic principle of this embodiment: The cover body 200 and the reflux cover body 500 can basically form a sealed cover body 200. The surface of the catalyst block can be dried by injecting hot drying air. The elevating drying mechanism 400 therein can be lifted. During the rising process, the sliding door mechanism 700 can be opened in a linkage manner. The dried catalyst block is driven by the positioning and conveying mechanism 300 to break away from the cover body 200, and at the same time, the catalyst block to be dried enters the cover body 200. At this time, when the elevating drying mechanism 400 descends, it drives the sliding door mechanism 700 to gradually close the cover body 200, and at the same time, the elastic linkage mechanism 600 can further correct the position of the catalyst block, facilitating a part of the elevating drying mechanism 400 to enter the inside of the catalyst block to realize simultaneous drying of the inside and outside of the catalyst block, which can reduce damage to the catalyst block and further improve the drying efficiency.

[0045] Referring to Figure 3 and Figure 4 , in order to be able to perform positioning conveyance on the catalyst block, the positioning and conveying mechanism 300 in this embodiment includes a conveying component and a guiding and positioning component provided on the conveying component. The conveying component is mainly used to hold the catalyst block and convey it, and the guiding and positioning component is used to position the catalyst block. Through cooperation with the elastic linkage mechanism 600, the catalyst block can be positioned more accurately, facilitating a part of the elevating drying mechanism 400 to enter the inside of the catalyst block for drying.

[0046] Referring to Figure 3 and Figure 4, in this embodiment, the conveying assembly includes a driving chain shaft 310 and a driven chain shaft 320. A servo motor is drivingly connected to the driving chain shaft 310. A conveying chain plate 330 is drivingly connected between the driving chain shaft 310 and the driven chain shaft 320. The guiding and positioning assembly is arranged on the conveying chain plate 330. The driving chain shaft 310 can be driven to rotate by a servo motor (not shown in the figure), so as to drive the conveying chain plate 330 to rotate cyclically for conveying catalyst blocks. The servo motor is convenient to control. The cooperation between the guiding and positioning assembly and the elastic linkage mechanism 600 can better control the position of the catalyst blocks, facilitating the internal and external drying of the catalyst blocks.

[0047] Refer to Figure 4 , specifically, the guiding and positioning assembly includes a positioning groove 340 arranged on the conveying chain plate 330 and guiding inclined plates 350 arranged on both sides at the front end of the positioning groove 340. The two guiding inclined plates 350 incline towards the outside of the positioning groove 340. When conveying the catalyst blocks, the catalyst blocks can be basically guided into the positioning groove 340 through the guiding inclined plates 350, and the catalyst blocks can be accurately fixed inside the positioning groove 340 by being driven by the elastic linkage mechanism 600, facilitating the partial entry of the lifting and drying mechanism 400 into the inside of the catalyst blocks for drying.

[0048] In this embodiment, the positioning grooves 340 are arranged in rows on the conveying chain plate 330, with a total of 2 groups. Of course, according to actual needs, it can also be set to multiple groups, and the quantity of each group can also be set according to actual needs.

[0049] Refer to Figures 3-5 , in order to be able to dry the inside of the catalyst blocks, the lifting and drying mechanism 400 in this embodiment includes a telescopic power member 410 arranged on the top wall of the cover body 200. The cover body 200 is of a cuboid structure. Wedge-shaped guide rails 420 are arranged at the four corner positions of the cover body 200. The telescopic shaft of the telescopic power member 410 extends into the cover body 200 and is connected to a gas distribution assembly. The gas distribution assembly is communicated with an interface pipe 440 arranged on the top wall of the cover body 200 through a hose 430. The telescopic power member 410 can drive the gas distribution assembly to move up and down inside the cover body 200, thereby realizing the opening or closing of the sliding door mechanism 700 and the action of the elastic linkage mechanism 600.

[0050] Of course, this embodiment should also include a control system, which is mainly used to control the coordinated actions of the servo motor and the telescopic power member 410. The telescopic power member 410 in this embodiment can be an electric cylinder or a cylinder, etc.

[0051] Refer to Figure 6, in this embodiment, the gas distribution component includes a gas distribution cavity plate 450 connected to the telescopic shaft. Wedge-shaped grooves 460 are provided at the four corners of the gas distribution cavity plate 450. The wedge-shaped grooves 460 are slidably engaged with wedge-shaped guide rails 420. A plurality of gas needles 470 are communicated with the lower side of the gas distribution cavity plate 450. A plurality of air dispersion holes 480 are provided on each gas needle 470. The elastic linkage mechanism 600 is arranged on the lower side of the gas distribution cavity plate 450.

[0052] The gas distribution cavity plate 450 therein is connected to the telescopic shaft of the telescopic power member 410 and can move up and down. Through the cooperation of the wedge-shaped groove 460 and the wedge-shaped guide rail 420, the gas distribution cavity plate 450 can be better positioned to move up and down precisely. Specifically, when moving upward, it can drive the sliding door mechanism 700 to open, enabling the catalyst block to enter and exit the housing 200. When it descends, it can drive the elastic linkage mechanism 600 to act first, pushing the catalyst block into the positioning groove 340 first. Continuing to descend, the gas needle 470 can be inserted into the holes in the catalyst block. Since the gas distribution cavity plate 450 is connected to the dry hot air through the hose 430 and the interface pipe 440, the dry hot air can be discharged through the air dispersion holes 480 to dry the inside of the catalyst block, improving the drying efficiency.

[0053] The gas needles 470 in this embodiment are arranged in an array. Each group of array gas needles 470 is used to dry a high-hole honeycomb catalyst block. An elastic linkage mechanism 600 is provided beside each group of array gas needles 470. Each group of array gas needles 470 can be aimed at one catalyst block and can be inserted into the holes in the catalyst block to dry the inside of the catalyst block.

[0054] Refer to Figure 3 and Figure 7 , the elastic linkage mechanism 600 in this embodiment includes a telescopic member arranged on the gas distribution cavity plate 450. A touch plate 610 is provided at the lower part of the telescopic member. A slope pushing portion 611 is provided on the touch plate 610 facing the guiding inclined plate 350.

[0055] When the catalyst block enters the inside of the housing 200, the telescopic power member 410 drives the gas distribution cavity plate 450 to move downward step by step, driving the sliding door mechanism 700 to act and gradually close the housing 200. At the same time, it drives the touch plate 610 to move downward. Since the touch plate 610 has a slope pushing portion 611, it gradually pushes the catalyst block completely into the positioning groove 340 during the downward movement to complete the positioning. Due to the provision of the elastic member, after the catalyst block is pushed in place, the gas distribution cavity plate 450 can continue to compress the elastic member and move downward, without hindering the gas needle 470 from entering the holes inside the catalyst block.

[0056] The telescopic member includes a perforated plate 620 connected to the lower side of the air distribution cavity plate 450. The upper end of the trigger plate 610 is slidably connected inside the perforated plate 620. A first spring (not shown in the figure) is provided between the trigger plate 610 and the perforated plate 620. The trigger plate 610 passes through the perforated plate 620. When the lower end of the trigger plate 610 contacts the conveying chain plate 330, the telescopic power member 410 can continue to drive the air distribution cavity plate 450 downward. At this time, the first spring contracts and does not block the downward movement of the air distribution cavity plate 450.

[0057] The sliding door mechanism 700 in this embodiment includes a slot provided on the cover body 200. Connecting rods 710 that slide inside the slot are provided on both sides of the air distribution cavity plate 450. A sliding door 720 is connected to the outer ends of the connecting rods 710. When the air distribution cavity plate 450 moves up and down, the sliding door 720 can be driven to move up and down through the connecting rods 710, thereby realizing the intermittent opening and closing of the sliding door 720.

[0058] The lower part of the reflux cover body 500 in this embodiment is connected with a reflux pipe 510. Through the reflux pipe 510 and the suction device, the dry hot air can be refluxed to form a hot air flow cycle. While accelerating drying, the dry hot air can be recycled.

[0059] Embodiment Two: Refer to Figure 8 and Figure 9 A drying device for preparing a high-hole honeycomb catalyst proposed in this embodiment includes a device frame body 100. The device frame body 100 bears the entire device and can be welded with steel materials. A cover body 200 is provided on the upper part of the device frame body 100. A positioning and conveying mechanism 300 is provided on the device frame body 100 for conveying catalyst blocks. An elevating and drying mechanism 400 is provided inside the cover body 200. A reflux cover body 500 provided on the device frame body 100 is used for refluxing dry hot air. This embodiment further includes an elastic linkage mechanism 600 provided on the elevating and drying mechanism 400, and a sliding door mechanism 700 that is slidably arranged on both sides of the cover body 200 and is connected to the elevating and drying mechanism 400.

[0060] Its basic working principle and some specific optimization and improvement schemes are the same as those in Embodiment One. The difference from Embodiment One is that the telescopic member includes a fixing plate 630 connected to the lower side of the air distribution cavity plate 450. The trigger plate 610 is slidably connected to the fixing plate 630. A telescopic rod 640 is provided between the lower side of the air distribution cavity plate 450 and the upper end of the trigger plate 610. A second spring 650 is sleeved on the outer peripheral side of the telescopic rod 640. The outer peripheral side of the second spring 650 does not exceed the side of the trigger plate 610 facing the guiding inclined plate 350. The upper end of the second spring 650 is fixed to the lower side surface of the air distribution cavity plate 450, and the lower end is fixed to the upper side surface of the trigger plate 610.

[0061] Since there may be a connecting convex part between the touch plate 610 and the perforated plate 620 in the first embodiment, which may scratch the catalyst block, in this embodiment, the second spring 650 and the telescopic rod 640 are adopted, and the outer peripheral side of the second spring 650 does not exceed the side of the touch plate 610 facing the guiding inclined plate 350, so there is no connecting convex, avoiding scratching and damage to the peripheral side of the catalyst block.
