Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas collection device for rubber vulcanization. Background Technology

[0002] Rubber vulcanization is a key process in rubber processing. By heating and adding vulcanizing agents, the rubber molecular chains are cross-linked, thereby improving the physical and mechanical properties of the rubber. This process generates complex waste gas, known as rubber vulcanization waste gas. Rubber product manufacturing typically uses raw rubber as the base material and adds various chemical additives. These substances undergo volatilization, pyrolysis, or chemical reactions during vulcanization, releasing various gaseous pollutants. Rubber vulcanization waste gas is a comprehensive product of the pyrolysis of raw materials, the volatilization of additives, and chemical reactions during rubber processing. Its treatment requires a combination of process optimization and end-of-pipe treatment technologies to achieve pollutant reduction and compliance with emission standards.

[0003] In existing technologies, rubber vulcanization waste gas collection devices are mainly used to collect waste gas during the vulcanization process in rubber product manufacturing. They efficiently capture the waste gas generated during vulcanization and transport it to the subsequent treatment system. However, during use, after collecting waste gas for a long time, a large amount of dust and rubber particle impurities accumulate on the inner wall of the collection hood, increasing the workload of manual maintenance and affecting the smoothness of air intake. Furthermore, when collecting waste gas, pre-filtration is usually not performed, increasing the burden of subsequent waste gas treatment.

[0004] Therefore, a rubber vulcanization waste gas collection device was proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a rubber vulcanization waste gas collection device, which solves the technical problems that after a long period of waste gas collection, a large amount of dust and rubber particle impurities will accumulate on the inner wall of the collection hood, increasing the workload of manual maintenance, affecting the smoothness of air intake, and that the waste gas is usually not pre-filtered during collection, increasing the burden of subsequent waste gas treatment. The device achieves the purpose of regular cleaning and pre-filtration.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber vulcanization waste gas collection device, comprising a collection pipe, wherein a first suction pipe is equidistantly connected to the outer wall of the collection pipe, a second suction pipe is provided at the other end of the first suction pipe, a gas collection hood is connected to one end of the second suction pipe, a periodic cleaning component is provided on the outer wall of the gas collection hood, and a pre-filter component is provided between the other end of the second suction pipe and the other end of the second suction pipe.

[0007] Preferably, the periodic cleaning component specifically includes: a collar disc, fixedly sleeved on the outer wall of the gas collection hood; a protective arc plate, fixedly installed at the bottom of the gas collection hood; a micro motor, fixedly installed on the top of the collar disc; and a gear sleeve, rotatably connected to the outer wall of the gas collection hood.

[0008] Preferably, the output end of the micro motor is fixedly mounted with a rotating shaft, the other end of the rotating shaft movably passes through the top of the collar disk and extends to the bottom of the collar disk, and a gear is fixedly mounted on the other end of the rotating shaft, the surface of the gear sleeve meshing with the surface of the gear.

[0009] Preferably, a connecting rod is fixedly installed at equal intervals around the bottom circumference of the gear sleeve. A connecting block is fixedly connected to the bottom of the connecting rod, and a slanted scraper is fixedly installed on the top of the connecting block. The outer wall of the slanted scraper is in contact with the inner wall surface of the gas collecting hood. The gear and gear sleeve are rotated by a micro motor, which drives the connecting rod and the slanted scraper to move circumferentially along the inner wall of the gas collecting hood, automatically scraping off the attached rubber particles, dust and impurities. This avoids frequent manual disassembly and cleaning. The slanted scraper is in close contact with the inner wall of the gas collecting hood, ensuring thorough cleaning without dead corners. This prevents airflow blockage or equipment corrosion caused by the accumulation of impurities. The collar disc and protective arc plate provide protection for the internal mechanical parts, thereby achieving the effect of regular cleaning of the gas collecting hood.

[0010] Preferably, the pre-filtering component specifically includes: a connecting tube, which is installed between the other end of straw one and the other end of straw two; the outer wall of the connecting tube is provided with sealing holes at equal intervals; a sealing arc plate is provided between the inner walls of the sealing holes; a sealing sleeve is fixedly installed on the outer wall of the sealing arc plate; the outer wall of the sealing sleeve is in contact with the inner wall of the sealing hole; and a buckle is fixedly installed on the top of the sealing arc plate.

[0011] Preferably, positioning blocks are fixedly connected at equal intervals around the outer circumference of the sealing arc plate, a connecting ring is fixedly installed at the bottom of the sealing arc plate, and a filter screen is fixedly installed between the inner walls of the connecting ring.

[0012] Preferably, a fixing block is uniformly and equidistantly fixed to the outer circumference of the connecting pipe, and a sliding nail rod is fixedly installed on one side of the fixing block. A sliding arc plate is slidably connected to the outer wall of the sliding nail rod.

[0013] Preferably, a spring is slidably connected to the outer wall of the sliding nail rod. One end of the spring contacts one side of the sliding arc plate, and the other end of the spring contacts one side of the fixing block. A positioning rod is fixedly connected equidistantly to the other side of the sliding arc plate. The other end of the positioning rod extends to the inner wall of the positioning block and engages with it. The filter screen mounted on the sealing arc plate can intercept particulate pollutants in the exhaust gas, reducing the load on subsequent treatment equipment. The sealing arc plate can be quickly installed through the buckle, positioning block, and sliding arc plate. The sliding nail rod and spring provide elastic positioning. The positioning rod engages with the positioning block to ensure sealing. During maintenance, the sealing arc plate with the filter screen can be removed simply by pulling the buckle. Cleaning or replacement can be completed without tools, greatly shortening downtime for maintenance and achieving the effect of pre-filtration.

[0014] This utility model provides a gas collection device for rubber vulcanization waste gas. It has the following beneficial effects: (1) This utility model can regularly clean the inner wall of the gas collection hood by setting a regular cleaning component. The micro motor is started to drive the gear to rotate, which in turn drives the gear sleeve, connecting rod and connecting block to rotate, so that the inclined scraper scrapes the inner wall of the gas collection hood. The collection box is used to collect the scraped dust and particulate pollutants, which can regularly remove the dust, rubber particles and other impurities accumulated in the gas collection hood and pipes, reduce the workload of manual maintenance, and thus achieve the effect of positioning cleaning.

[0015] (2) This utility model can pre-filter the rubber vulcanization waste gas by setting a pre-filter component. The waste gas generated by the bottom equipment is absorbed by the gas collection hood, suction pipe II, and suction pipe I. The waste gas enters the connecting pipe and passes through two layers of filter screens. The first layer is a coarse filter screen to filter large impurities, and the second layer is a fine filter screen to filter small impurities, reducing the burden on subsequent equipment. It performs preliminary filtration of particulate matter, rubber debris and other impurities, reducing the burden on subsequent waste gas treatment equipment, thereby achieving the effect of pre-filtration.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] Example 1: Based on the existing problems that existing gas collection hoods accumulate a large amount of dust and rubber particles on their inner walls after long-term waste gas collection, increasing the workload of manual maintenance, affecting the smoothness of air intake, and that the waste gas is usually not pre-filtered during collection, increasing the burden of subsequent waste gas treatment, the preferred embodiment of the rubber vulcanization waste gas collection device provided by this utility model is as follows: Figure 1-4 As shown: A rubber vulcanization waste gas collection device includes a collection pipe 1, a suction pipe 2 is installed at equal intervals on the outer wall of the collection pipe 1, a suction pipe 3 is provided at the other end of the suction pipe 2, a gas collection hood 4 is installed at one end of the suction pipe 3, a periodic cleaning component 5 is provided on the outer wall of the gas collection hood 4, and a pre-filter component 6 is provided between the other end of the suction pipe 3 and the other end of the suction pipe 3.

[0021] The regular cleaning component 5 specifically includes: a collar disc 511, which is fixedly sleeved on the outer wall of the gas collection hood 4; a protective arc plate 512, which is fixedly installed at the bottom of the gas collection hood 4; a micro motor 513, which is fixedly installed on the top of the collar disc 511; and a gear sleeve 515, which is rotatably connected to the outer wall of the gas collection hood 4.

[0022] The output end of the micro motor 513 is fixedly mounted with a rotating shaft. The other end of the rotating shaft passes through the top of the collar disk 511 and extends to the bottom of the collar disk 511. The other end of the rotating shaft is fixedly mounted with a gear 514. The surface of the gear sleeve 515 meshes with the surface of the gear 514.

[0023] A connecting rod 516 is fixedly installed at equal intervals around the bottom circumference of the gear sleeve 515. A connecting block 517 is fixedly connected to the bottom of the connecting rod 516. An inclined scraper 518 is fixedly installed on the top of the connecting block 517. The outer wall of the inclined scraper 518 is in contact with the inner wall surface of the gas collection hood 4.

[0024] In this example, the inner wall of the air collection hood 4 can be cleaned periodically by setting the periodic cleaning component 5. The micro motor 513 is started to drive the gear 514 to rotate, which in turn drives the gear sleeve 515, connecting rod 516, and connecting block 517 to rotate, so that the inclined scraper 518 scrapes the inner wall of the air collection hood 4. The scraped dust and particulate pollutants are collected using a collection box, thereby achieving the effect of targeted cleaning.

[0025] Example 2: Based on Embodiment 1, a preferred embodiment of the rubber vulcanization waste gas collection device provided by this utility model is, for example... Figure 1-4 As shown: The pre-filter component 6 specifically includes: a connecting pipe 611, which is connected between the other end of the first straw 2 and the other end of the second straw 3; the outer wall of the connecting pipe 611 is provided with sealing holes at equal intervals, and a sealing arc plate 612 is provided between the inner walls of the sealing holes. A sealing sleeve is fixedly installed on the outer wall of the sealing arc plate 612, and the outer wall of the sealing sleeve fits against the inner wall of the sealing hole. A buckle 613 is fixedly installed on the top of the sealing arc plate 612.

[0026] Positioning blocks 614 are fixedly connected at equal intervals around the outer circumference of the sealing arc plate 612. A connecting ring 615 is fixedly installed at the bottom of the sealing arc plate 612. A filter screen 616 is fixedly installed between the inner walls of the connecting ring 615.

[0027] A fixing block 617 is fixedly installed at equal intervals around the outer circumference of the connecting pipe 611. A sliding nail rod 618 is fixedly installed on one side of the fixing block 617. A sliding arc plate 619 is slidably connected to the outer wall of the sliding nail rod 618.

[0028] A spring 6111 is slidably connected to the outer wall of the sliding nail rod 618. One end of the spring 6111 is in contact with one side of the sliding arc plate 619, and the other end of the spring 6111 is in contact with one side of the fixing block 617. A positioning rod 6112 is fixedly connected to the other side of the sliding arc plate 619 at equal intervals around its circumference. The other end of the positioning rod 6112 extends to the inner wall of the positioning block 614 and engages with it.

[0029] In this example, the pre-filter component 6 can be used to pre-filter the inhaled rubber vulcanization waste gas. The waste gas generated by the bottom equipment is absorbed by the gas collection hood 4, suction pipe 2 3, and suction pipe 1 2. The waste gas enters the connecting pipe 611 and passes through two layers of filter screens 616. The first layer is a coarse filter screen to filter large impurities, and the second layer is a fine filter screen to filter small impurities, reducing the burden on subsequent equipment and thus achieving the effect of pre-filtration.

[0030] Working principle: First, when the inhaled rubber vulcanization waste gas needs to be pre-filtered, the waste gas generated by the bottom equipment is absorbed through the gas collection hood 4. The waste gas enters the collection pipe 1 through suction pipe 2 3 and suction pipe 1 2 for absorption, and then enters the waste gas treatment device. When the waste gas enters the connecting pipe 611, it passes through two layers of filter screens 616. The first layer is a coarse filter screen to filter large impurities, and the second layer is a fine filter screen to filter small impurities, reducing the burden on subsequent equipment. When the inner wall of the gas collection hood 4 needs to be cleaned regularly, the micro motor 513 is started to drive the gear 514 to rotate, which in turn drives the gear sleeve 515, connecting rod 516, and connecting block 517 to rotate, so that the inclined scraper 518 cleans the inner wall of the gas collection hood 4. The wall is scraped, and the scraped dust and particulate pollutants are collected using a collection box. Regular cleaning keeps the inner wall of the gas collection hood 4 smooth, ensuring that the exhaust gas can be quickly and smoothly sucked into the pipe, avoiding poor ventilation problems caused by the accumulation of impurities. The protective arc plate 512 and the collar disc 511 protect the gear sleeve 515. When the filter screen 616 needs to be removed, push the sliding arc plate 619 to slide on the sliding nail rod 616, compress the spring 6111, and remove the positioning rod 6112 from the positioning block 614. The sealing arc plate 612 and the connecting ring 615 can be removed from the connecting pipe 611 through the buckle 613, and the filter screen 616 can be cleaned, thereby achieving the functions of pre-filtration and regular cleaning.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
