Description

Technical Field

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

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

[0003] Generally, it is made through multiple processes such as mixing, pre-extrusion, extrusion molding, primary and secondary drying, and calcination. After extrusion molding, it needs to be dried. In the prior art, a drying oven is generally used for drying.

[0004] For example, in the prior art, there is a patent document with the announcement number CN115900271B, which discloses a drying device for preparing a high-porous honeycomb catalyst, comprising a drying chamber for placing catalyst blocks, wherein a support plate and a porous partition are provided in the drying chamber, and the catalyst blocks are placed between the partition and the top of the drying chamber, and the support plate is located below the partition, and an air duct for inputting dry hot air into the drying chamber is provided on the support plate, an air chamber is formed between the support plate and the partition, and the dry hot air first enters the air chamber and then passes upward through the partition, and a movable block driven by a screw motor is further provided between the partition and the top of the drying chamber, and the screw motor comprises a motor body, The screw rod and the limit rod, the movable block reciprocates in the vertical direction in the drying chamber to form a disturbance to the catalyst block, the movable block and the screw rod are connected by a thread, and the limit rod is slidably connected to the movable block. The movable block is spherical and hollow. A self-locking air nozzle is provided at the top and bottom of the movable block. A plurality of columnar air bags connected to the interior of the movable block are provided on the outer wall of the movable block. An air inlet pipe connected to the air source is provided on the partition, and an air outlet pipe connected to the outside is provided on the top of the drying chamber. The air inlet pipe, air outlet pipe and 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 screw motor to drive the movable block to perform linear reciprocating motion, which can realize the change of the position of the catalyst block in the drying chamber, so that each catalyst block will be in a state of intermittently moving away from or close to the air outlet end of the air duct, thereby achieving uniform drying of several catalyst blocks. The dry hot air moving from bottom to top realizes the drying effect on the catalyst block, increases the contact area between the dry hot air and the catalyst block, and improves the drying efficiency.

[0006] After studying the existing technology, especially the above-mentioned technical solution, 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 formed, and the airbag is not very realistic during use, which can easily 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, comprising a device frame, a cover body provided on the upper part of the device frame, 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, a reflux cover body provided on the device frame, an elastic linkage mechanism provided on the lifting and drying mechanism, and a sliding door mechanism connected to the lifting and drying mechanism and slidingly provided on both sides of the cover body.

[0009] By adopting the above technical solution: 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 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 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 outside, which can reduce damage to the catalyst block and further improve the drying efficiency.

[0010] As a further optimization and improvement of the present 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 guide 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 this technical solution, the conveying assembly includes a driving chain shaft and a driven chain shaft, the driving chain shaft is driven and connected to a servo motor, a conveying chain plate is connected between the driving chain shaft and the driven chain shaft, and the guide positioning assembly is arranged on the conveying chain plate.

[0013] By adopting the above technical solution: the servo motor can drive the active chain shaft to rotate, thereby driving the conveying chain plate to rotate in a cycle, which is used to convey the catalyst block. The servo motor is easy to control, and the guide positioning component cooperates with the elastic linkage mechanism to better control the position of the catalyst block, which is convenient for drying the catalyst block inside and outside.

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

[0015] By adopting the above technical solution: when transporting the catalyst block, the catalyst block can be basically guided into the positioning groove through the guide inclined plate, and the catalyst block can be accurately fixed inside the positioning groove under the drive of the elastic linkage mechanism, which facilitates the lifting and drying mechanism to enter the interior of the catalyst block for drying.

[0016] As a further optimization and improvement of the present technical solution, the lifting and drying mechanism includes a telescopic power part arranged on the top wall of the cover body. The cover body is a rectangular structure, and wedge-shaped guide rails are provided at the four corners of the cover body. The telescopic shaft of the telescopic power part is extended into the interior of the cover body and is connected to an air distribution component. The air distribution component is connected to 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 air distribution assembly to move up and down inside the cover body, thereby realizing the opening or closing of the sliding door mechanism and the action of the elastic linkage mechanism.

[0018] As a further optimization and improvement of the present technical solution, the air separation assembly includes an air separation cavity plate connected to the telescopic shaft, wedge-shaped grooves are provided at the four corners of the air separation cavity plate, the wedge-shaped grooves are slidably fitted on the wedge-shaped guide rails, and the lower side of the air separation cavity plate is connected to a plurality of air needles, each of the air needles is provided with a plurality of air diffusion holes, and the elastic linkage mechanism is arranged on the lower side of the air separation cavity plate.

[0019] By adopting the above technical solution: the air cavity plate is connected to the telescopic shaft of the telescopic power part and can move up and down. The air cavity plate can be better positioned through the cooperation of the wedge groove and the wedge 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 cavity 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.

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

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

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

[0023] By adopting the above technical solution: 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, it gradually pushes the catalyst block completely into the positioning groove during the downward movement 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 without hindering the gas needle from entering the hole of 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 cavity plate, the upper end of the touch plate is slidably connected to the inside of 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 contacts the conveyor chain plate, the telescopic power part can continue to drive the air cavity plate to move downward. At this time, the first spring contracts and does not block the downward movement of the air cavity plate.

[0026] As a further optimization and improvement of the present technical solution, the telescopic part includes a fixed plate connected to the lower side of the air dividing cavity plate, the touch plate is slidably connected to the fixed plate, a telescopic rod is provided on the lower side of the air dividing cavity plate and the upper end of the touch plate, a second spring is sleeved on the outer peripheral side of the telescopic rod, and the outer peripheral side of the second spring does not exceed the side of the touch plate facing the guide inclined plate.

[0027] By adopting the above technical solution: the above-mentioned contact plate and the perforated plate have a connecting protrusion, which may scratch the catalyst block. Therefore, this technical solution adopts a second spring and a telescopic rod, and the outer peripheral side of the second spring does not exceed the side of the contact plate facing the guide inclined plate, so there is no connecting protrusion, avoiding scratches and damage to the peripheral side of the catalyst block.

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

[0029] By adopting the above technical solution, the touch plate can be made to slide relative to the fixed plate.

[0030] As a further optimization and improvement of this technical solution, the sliding door mechanism includes a strip groove arranged on the cover body, and connecting rods sliding inside the strip groove are provided on both sides of the air cavity plate, and the outer ends of the connecting rods are connected to the sliding door.

[0031] By adopting the above technical solution: when the air cavity plate moves up and down, the sliding door can be driven to move up and down by the connecting rod, thereby realizing intermittent opening and closing of the sliding door.

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

[0033] By adopting the above technical solution: the dry hot air can be refluxed through the reflux pipe and the suction equipment to form a hot air flow circulation, which can accelerate the drying and recycle the dry hot air.

[0034] The working principle and beneficial effects of the present invention are:

[0035] 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 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, reducing damage to the catalyst block, and further improving the drying efficiency.

[0036] 2. In the present invention, the air cavity plate is connected to the telescopic shaft of the telescopic power part and can move up and down. The cooperation of the wedge-shaped groove and the wedge-shaped guide rail can better position the air cavity plate and make it move up and down accurately. Specifically, when it moves 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 cavity 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.

[0037] 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, it gradually pushes the catalyst block completely into the positioning groove during the downward movement 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 without hindering the gas needle from entering the hole of the catalyst block.

[0038] 4. The dry hot air can be refluxed through the reflux pipe and suction equipment to form a hot air flow circulation, which can speed up the drying process and recycle the dry hot air. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making any creative efforts are within the scope of protection of the present invention.

[0052] The present invention includes two specific embodiments, and is certainly not limited to the limitations of the following specific embodiments. It mainly lies in the inventive concept of the present invention. The main inventive concept of the present invention as a whole 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. During drying, in order to ensure the 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, which facilitates 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.

[0053] To this end, the present invention specifically provides the following two embodiments, which are as follows:

[0054] Example 1:

[0055] Reference Figure 1-Figure 7 The present embodiment proposes a drying device for preparing a high-porous honeycomb catalyst, comprising a device frame 100, which carries the entire device and can be welded from steel materials. A cover 200 is provided on the upper part of the device frame 100, and a positioning and conveying mechanism 300 is provided on the device frame 100 for conveying catalyst blocks. A lifting and drying mechanism 400 is provided inside the cover 200, and further comprises a reflux cover 500 provided on the lower side of the device frame 100. The reflux cover 500 corresponds to the cover 200, basically forming a sealed space for reflux drying hot air. The present embodiment further comprises an elastic linkage mechanism 600 provided on the lifting and drying mechanism 400, and a sliding door mechanism 700 connected to the lifting and drying mechanism 400 and slidingly provided on both sides of the cover 200.

[0056] The basic principle of this embodiment is: the cover body 200 and the reflux cover body 500 can basically form a sealed cover body 200, and the surface of the catalyst block can be dried by injecting dry hot air. The lifting and drying mechanism 400 can be lifted and lowered. During the lifting process, the sliding door mechanism 700 can be opened in a linkage manner. The dried catalyst block is separated from the cover body 200 by the positioning and conveying mechanism 300, and the catalyst block to be dried enters the inside of the cover body 200. At this time, the lifting and drying mechanism 400 descends while driving the sliding door mechanism 700 to gradually close the cover body 200, and at the same time, the position of the catalyst block can be further adjusted through the elastic linkage mechanism 600, so that the lifting and drying mechanism 400 can partially enter the inside of the catalyst block, thereby achieving simultaneous drying of the inside and outside of the catalyst block, reducing damage to the catalyst block, and further improving the drying efficiency.

[0057] Reference Figure 3 and Figure 4To ensure the catalyst blocks are positioned and transported, the positioning and conveying mechanism 300 in this embodiment includes a conveying assembly and a guide and positioning assembly mounted on the conveying assembly. The conveying assembly primarily supports and transports the catalyst blocks, while the guide and positioning assembly positions the catalyst blocks. Working in conjunction with the elastic linkage mechanism 600, the catalyst blocks can be more accurately positioned, allowing the lifting and drying mechanism 400 to partially enter the catalyst blocks for drying.

[0058] Reference Figure 3 and Figure 4 The conveying assembly in this embodiment includes a driving chain shaft 310 and a driven chain shaft 320. The driving chain shaft 310 is driven and connected to a servo motor. A conveying chain plate 330 is connected between the driving chain shaft 310 and the driven chain shaft 320. The guide and positioning assembly is arranged on the conveying chain plate 330. The servo motor (not shown in the figure) can drive the driving chain shaft 310 to rotate, thereby driving the conveying chain plate 330 to rotate in a cycle for conveying catalyst blocks. The servo motor is easy to control. The guide and positioning assembly cooperates with the elastic linkage mechanism 600 to better control the position of the catalyst block, which is convenient for drying the inside and outside of the catalyst block.

[0059] Reference Figure 4 Specifically, the guide and positioning assembly includes a positioning groove 340 provided on the conveying chain plate 330 and a guide inclined plate 350 provided on both sides of the front end of the positioning groove 340. The two guide inclined plates 350 are inclined toward the outside of the positioning groove 340. When conveying the catalyst block, the catalyst block can be basically guided into the interior of the positioning groove 340 through the guide inclined plate 350. The catalyst block can be accurately fixed inside the positioning groove 340 under the drive of the elastic linkage mechanism 600, which facilitates the lifting and drying mechanism 400 to partially enter the interior of the catalyst block for drying.

[0060] The positioning grooves 340 in this embodiment are arranged in rows on the conveying chain plate 330 in two groups in total. Of course, according to actual needs, they can also be arranged in multiple groups, and the number of each group can also be set according to actual needs.

[0061] Reference Figure 3-Figure 5 In order to dry the interior of the catalyst block, 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 a rectangular structure, and wedge-shaped guide rails 420 are provided at the four corners of the cover body 200. The telescopic shaft of the telescopic power member 410 extends into the interior of the cover body 200 and is connected to an air separation component. The air separation component is connected to the 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 air separation component 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.

[0062] 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 pneumatic cylinder.

[0063] Reference Figure 6 The air separation component in this embodiment includes an air separation chamber plate 450 connected to the telescopic shaft, and wedge-shaped grooves 460 are provided at the four corners of the air separation chamber plate 450. The wedge-shaped grooves 460 are slidably fitted on the wedge-shaped guide rail 420. The lower side of the air separation chamber plate 450 is connected to a plurality of air needles 470, and each of the air needles 470 is provided with a plurality of air diffusion holes 480. The elastic linkage mechanism 600 is arranged on the lower side of the air separation chamber plate 450.

[0064] The air chamber plate 450 is connected to the telescopic shaft of the telescopic power part 410 and can move up and down. The cooperation of the wedge-shaped groove 460 and the wedge-shaped guide rail 420 can better position the air chamber plate 450 and make it move up and down accurately. Specifically, when it moves upward, it can drive the sliding door mechanism 700 to open, so that the catalyst block can enter and exit the cover body 200. When it descends, it can pre-drive the elastic linkage mechanism 600 to move, first push the catalyst block into the positioning groove 340, and continue to descend. The air needle 470 can be inserted into the hole in the catalyst block. Since the air chamber plate 450 is connected to dry hot air through the hose 430 and the interface pipe 440, the dry hot air can be discharged through the air diffusion hole 480 to dry the catalyst block internally, thereby improving the drying efficiency.

[0065] The air needles 470 in this embodiment are arranged in an array, and each group of array air needles 470 is used to dry a high-porous honeycomb catalyst block. An elastic linkage mechanism 600 is provided next to each group of array air needles 470. Each group of array air needles 470 can target a catalyst block and can be inserted into the holes in the catalyst block to dry the inside of the catalyst block.

[0066] Reference Figure 3 and Figure 7 The elastic linkage mechanism 600 in this embodiment includes a telescopic member arranged on the air chamber plate 450, and a touch plate 610 is provided at the lower part of the telescopic member. The touch plate 610 is provided with an inclined push portion 611 on the side facing the guide inclined plate 350.

[0067] When the catalyst block enters the interior of the cover body 200, the telescopic power part 410 drives the air cavity plate 450 to move downward step by step, drives the sliding door mechanism 700 to gradually close the cover body 200, and drives the touch plate 610 to move downward at the same time. Since the touch plate 610 has an inclined pushing part 611, during the downward movement, the catalyst block is gradually pushed completely into the positioning groove 340 to complete the positioning. Since an elastic part is provided, after the catalyst block is pushed into place, the air cavity plate 450 can continue to compress the elastic part to move downward without hindering the gas needle 470 from entering the hole of the catalyst block.

[0068] The telescopic part includes a perforated plate 620 connected to the lower side of the air cavity plate 450, the upper end of the touch plate 610 is slidably connected to the inside of the perforated plate 620, and a first spring (not shown in the figure) is provided between the touch plate 610 and the perforated plate 620. The touch plate 610 is penetrated into the inside of the perforated plate 620. When the lower end of the touch plate 610 contacts the conveying chain plate 330, the telescopic power part 410 can continue to drive the air cavity plate 450 to move downward. At this time, the first spring contracts and does not block the downward movement of the air cavity plate 450.

[0069] The sliding door mechanism 700 in this embodiment includes a strip groove arranged on the cover body 200, and connecting rods 710 sliding inside the strip groove are provided on both sides of the air cavity plate 450. The outer end of the connecting rod 710 is connected to the sliding door 720. When the air cavity plate 450 moves up and down, the sliding door 720 can be driven to move up and down by the connecting rod 710, thereby realizing intermittent opening and closing of the sliding door 720.

[0070] The lower part of the return cover 500 in this embodiment is connected to a return pipe 510. The dry hot air can be returned through the return pipe 510 and the suction equipment to form a hot air flow circulation, which can accelerate the drying and recycle the dry hot air.

[0071] Example 2:

[0072] Reference Figure 8 and Figure 9 The present embodiment proposes a drying device for preparing a high-porous honeycomb catalyst, including a device frame 100, which carries the entire device and can be welded with steel materials. A cover 200 is provided on the upper part of the device frame 100, and a positioning and conveying mechanism 300 is provided on the device frame 100 for conveying catalyst blocks. A lifting and drying mechanism 400 is provided inside the cover 200, and a reflux cover 500 provided on the device frame 100 for reflux drying hot air. The present embodiment also includes an elastic linkage mechanism 600 provided on the lifting and drying mechanism 400, and a sliding door mechanism 700 connected to the lifting and drying mechanism 400 and slidingly provided on both sides of the cover 200.

[0073] Its basic working principle and some specific optimization and improvement schemes are the same as those of Example 1. The difference from Example 1 is that the telescopic part includes a fixed plate 630 connected to the lower side of the air dividing cavity plate 450, and the touch plate 610 is slidably connected to the fixed plate 630. A telescopic rod 640 is provided on the lower side of the air dividing cavity plate 450 and the upper end of the touch 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 touch plate 610 facing the guide inclined plate 350, wherein the upper end of the second spring 650 is fixed to the lower side of the air dividing cavity plate 450, and the lower end is fixed to the upper side of the touch plate 610.

[0074] Because the contact plate 610 and the perforated plate 620 of the first embodiment have a connecting protrusion, which may scratch the catalyst block, this embodiment uses a second spring 650 and a telescopic rod 640. The outer peripheral side of the second spring 650 does not extend beyond the side of the contact plate 610 facing the guide inclined plate 350. Therefore, there is no connecting protrusion, which avoids scratches and damage to the peripheral side of the catalyst block.
