Description

Technical Field

[0001] The utility model relates to the technical field of catalytic combustion devices, in particular to a dry-type filtering mechanism for a catalytic combustion integrated machine. Background Art

[0002] A catalytic combustion device refers to a device or equipment that burns under the action of a catalyst. The working principle of the catalytic combustion device is to use a catalyst to make the organic waste gas burn flamelessly at a lower ignition temperature, so that the organic waste gas is decomposed into non-toxic carbon dioxide and water vapor.

[0003] like Figure 3 As shown, it is a previous generation of dry-type filter mechanism installed on the catalytic combustion integrated machine. It is installed at the front end of the catalytic combustion integrated machine. Its main function is to dry-filter the exhaust gas before combustion treatment, so as to remove solid impurities in the exhaust gas and prevent solid impurities from entering the combustion chamber and affecting the subsequent catalytic combustion operation. However, the dry-type filter mechanism of this structure has the following shortcomings in actual use: the filter screen is vertically clamped in the box by two U-shaped fixing buckles, and then the filter screen is limited and locked on the fixing buckles with fasteners. This results in the need for operators to use tools to participate in the installation, disassembly, cleaning or replacement of the filter screen, which increases the workload and difficulty of the operator in actually installing and removing the filter screen, thereby reducing the convenience and efficiency of the actual use of the dry-type filter mechanism.

[0004] In view of this, it is particularly important to design and manufacture a dry filter mechanism that can realize tool-free and quick installation and removal between the filter screen plate and the box body in the catalytic combustion integrated machine. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the installation and removal of the filter screen plate of the traditional dry-type filtering mechanism for the catalytic combustion integrated machine requires the operator to use tools, the installation and removal is poor and the efficiency is low, and a dry-type filtering mechanism for the catalytic combustion integrated machine is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A dry filtering mechanism for a catalytic combustion integrated machine comprises a box body with an open front end, an air inlet pipe connected to the middle of the right end of the box body, an air outlet pipe connected to the middle of the left end of the box body, a sealed box door symmetrically mounted on the front end of the box body, and a plurality of filter screens equidistantly arranged on the inner side of the box body, the inner bottom of the box body is located below the plurality of filter screens and is fixedly connected with a lower concave fixing block, and the upper end of the box body is provided with a fixing mechanism for quickly and tool-free fixing of the filter screen on the lower concave fixing block.

[0008] As a further description of the above technical solution:

[0009] The fixing mechanism includes a slide cylinder integrally fixed to the upper end of the box body and located above the multiple filter screens, an upper concave fixing block movably mounted on the inner side of the slide cylinder and buckled with the upper ends of the filter screens, an inner screw seat integrally fixed to the middle part of the upper end of the slide cylinder, an outer stud screwedly mounted on the inner side of the inner screw seat and rotatably connected to the upper concave fixing block at the lower end, and an operating knob mounted on the upper end of the inner screw seat.

[0010] As a further description of the above technical solution:

[0011] The upper ends and lower ends of the plurality of filter screen plates are integrally formed with wedge-shaped blocks corresponding to the inner walls of the lower concave fixing block and the upper concave fixing block.

[0012] As a further description of the above technical solution:

[0013] Anti-skid rubber pads that fit the wedge-shaped blocks are installed on the inner sides of the lower concave fixing block and the upper concave fixing block.

[0014] As a further description of the above technical solution:

[0015] The upper end of the upper concave fixing block is symmetrically fixedly connected with two guide posts that penetrate the slide cylinder, and the slide cylinder is provided with through holes corresponding to the guide posts.

[0016] As a further description of the above technical solution:

[0017] The four corners at the lower end of the box body are all fixedly connected with mounting brackets, and the lower end of the mounting bracket is provided with a mounting hole.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] 1. In the utility model, the original dry-type filtering mechanism is scientifically and rationally improved, and a lower concave fixing block, a sliding cylinder, an upper concave fixing block and an outer stud are arranged on the box body. The filter screen plate can be pre-slid between the box body and the lower concave fixing block. When the adjusting knob is held and turned, under the spiral action between the outer stud and the inner stud, the upper concave fixing block can be pressed downward in the sliding cylinder and contact the upper end of the filter screen plate, thereby vertically fixing the filter screen plate in the box body. This structure can realize tool-free and quick installation and removal operation between the filter screen plate and the box body, effectively reducing the workload and difficulty of installing, disassembling, cleaning or replacing the filter screen plate, thereby improving the convenience and efficiency of the actual use of the dry-type filtering mechanism.

[0020] 2. In the utility model, the original U-shaped fixing buckle is improved into an inward-recessed fixing block, and a wedge-shaped block is arranged on the filter screen plate. The shape of the wedge-shaped block is wedge-shaped and can fit with the concave surface of the inward-recessed fixing block. Under the combined effect of the clamping force and gravity, the filter screen plate will be stably limited and fixed between the middle part of the lower inward-recessed fixing block and the upper inward-recessed fixing block. This structure can make the filter screen plate stably vertically limited and fixed inside the box body, reduce the force shaking, deviation and abnormal noise of the filter screen plate after installation, thereby improving the stability of the filter screen plate after installation.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 and Figure 2The utility model provides a technical solution: a dry-type filtering mechanism for a catalytic combustion integrated machine, comprising a box body 1 with an opening at the front end, an air inlet pipe 101 connected to the middle part of the right end of the box body 1, an air outlet pipe 102 connected to the middle part of the left end of the box body 1, a sealed box door 103 symmetrically rotated and installed at the front end of the box body 1, and a plurality of filter screens 2 equidistantly arranged on the inner side of the box body 1. The inner bottom of the box body 1 is located below the plurality of filter screens 2 and is fixedly connected with a lower concave fixing block 3. The upper end of the box body 1 is provided with a fixing mechanism for quickly and easily fixing the filter screen 2 on the lower concave fixing block 3 without tools.

[0028] Specifically, Figure 1 and Figure 2 As shown, the fixing mechanism includes a slide cylinder 104 which is integrally fixed to the upper end of the casing 1 and is located above the plurality of filter screen plates 2, an upper concave fixing block 4 which is movably mounted on the inner side of the slide cylinder 104 and is buckled with the upper end of the filter screen plate 2, an inner screw seat 105 which is integrally fixed to the middle part of the upper end of the slide cylinder 104, an outer stud 5 which is screwed and mounted on the inner side of the inner screw seat 105 and whose lower end is rotatably connected to the upper concave fixing block 4, and an operating knob 501 which is mounted on the upper end of the inner screw seat 105. The setting of the operating knob 501 facilitates the operator to hold and rotate and adjust the outer stud 5. When the outer stud 5 rotates, under the action of the spiral transmission between the outer stud 5 and the inner screw seat 105, the outer stud 5 can move upward or downward on the slide cylinder 104, thereby driving the upper concave fixing block 4 to move up and down in the slide cylinder 104.

[0029] Among them, the upper and lower ends of multiple filter screen panels 2 are integrally formed with wedge-shaped blocks 201 corresponding to the inner walls of the lower concave fixing block 3 and the upper concave fixing block 4, which can correspond to the concave parts of the lower concave fixing block 3 and the upper concave fixing block 4. When the filter screen panel 2 is subjected to the action of vertical force, it can be centered and locked between the lower concave fixing block 3 and the upper concave fixing block 4. The inner sides of the lower concave fixing block 3 and the upper concave fixing block 4 are installed with anti-slip rubber pads 6 that fit with the wedge-shaped blocks 201. On the one hand, the occurrence of rigid clamping or scratching problems between the filter screen panel 2 installed on the lower concave fixing block 3 and the upper concave fixing block 4 can be reduced. On the other hand, the connecting gaps between the filter screen panel 2 and the lower concave fixing block 3 and the upper concave fixing block 4 can be filled and sealed, thereby improving the stability and sealing of the filter screen panel 2 after assembly.

[0030] At the same time, the upper end of the upper concave fixing block 4 is symmetrically fixedly connected with two guide columns 401 that penetrate the slide cylinder 104. The slide cylinder 104 is provided with through holes corresponding to the guide columns 401. The arrangement of the guide columns 401 and the through holes, on the one hand, improves the stability of the vertical lifting movement of the upper concave fixing block 4 in the slide cylinder 104, and on the other hand, prevents the deflection movement of the upper concave fixing block 4 when the outer stud 5 rotates.

[0031] In addition, mounting brackets 106 are fixedly connected to the four corners of the lower end of the box body 1, and mounting holes 107 are opened at the lower ends of the mounting brackets 106. The arrangement of the mounting brackets 106 and the mounting holes 107 facilitates the installation and fixing of the box body 1 to the filtering station of the catalytic combustion integrated machine through fasteners.

[0032] Working principle: When the filter screen plate 2 needs to be installed in the box body 1, first, the operator can hold and reversely rotate the operating knob 501 in advance to drive the outer stud 5 to move upward in the inner screw seat 105 of the slide cylinder 104, and slide the upper concave fixing block 4 upward into the slide cylinder 104 to make room for the installation of the filter screen plate 2; secondly, place the lower end of the filter screen plate 2 on the concave part of the lower concave fixing block 3, and then slide it into the inner side of the box body 1 to adjust the filter screen plate 2 to In the vertical state, keep the wedge-shaped block 201 at the upper end of the filter screen plate 2 directly below the upper concave fixing block 4, then hold and turn the operating knob 501 in the forward direction, drive the outer stud 5 to move downward in the inner screw seat 105 of the slide cylinder 104, and the upper concave fixing block 4 can move horizontally downward in the slide cylinder 104, contact and squeeze the wedge-shaped block 201 at the upper end of the filter screen plate 2, and limit and fix the filter screen plate 2 on the inner side of the box body 1, thereby completing the tool-free quick installation operation of the filter screen plate 2.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
