Description

Technical Field

[0001] The utility model belongs to the technical field of bag dust collectors, and in particular relates to an environmentally friendly bag dust collector. Background Art

[0002] Bag dust collector is a dust removal device that is currently widely used. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and high specific gravity dust settle due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, thereby purifying the gas.

[0003] Currently available bag dust collectors are generally only suitable for filtering dry dust. Once they process air mixed with moisture, dust is likely to condense into lumps inside the bag dust collector, so that dust falling into the ash hopper will partially adhere to the inner wall of the ash hopper and cannot be discharged, thereby breeding bacteria. Therefore, when the dust-containing exhaust gas is processed next time, the bred bacteria will be mixed in the air after dust filtration, causing secondary pollution. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an environmentally friendly bag dust collector that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: an environmentally friendly bag-type dust collector, including a bag-type dust collector body, and also including: an ash hopper, fixedly connected to the discharge port at the lower end of the bag-type dust collector body, and an opening and closing valve is installed at the discharge pipe of the ash hopper; a circle of annular grooves is provided on the inner wall of the ash hopper; an outer gear ring is rotatably connected in the annular groove; a plurality of scrapers are fixedly connected to the inner side of the outer gear ring at equal intervals around the circumference, and slide against the inner wall of the ash hopper; an annular cavity is provided in the side wall of the ash hopper; an annular electric heating plate is fixedly connected in the annular cavity; a driving mechanism for driving the outer gear ring to rotate is installed on the ash hopper.

[0006] Furthermore, the driving mechanism includes a motor and a gear, the motor is fixedly connected to one side of the ash hopper through a support plate, the gear is fixedly connected to the output end of the motor, the gear and the outer gear ring are on the same horizontal plane, and a through groove that penetrates the annular groove is provided on the side of the ash hopper close to the gear, and the side of the gear close to the ash hopper is located in the through groove and meshes with the outer gear ring.

[0007] In order to facilitate improving the smoothness of dust discharge, a mounting rod is vertically arranged in the middle position inside the ash hopper, the scraper and the mounting rod are fixedly connected by a connecting rod, and a spiral propulsion blade is fixedly connected to the mounting rod at a position inside the discharge pipe.

[0008] In order to prevent the agglomerated dust from being retained at the position of the upper pipe opening of the discharge pipe and being unable to be discharged, the spiral propulsion blade further extends upward into the ash hopper.

[0009] In order to prevent some dust from staying on the connecting rod, further, the upper surface of the connecting rod is an arc-shaped surface.

[0010] In order to reduce the damage of the scraper to the inner wall of the ash hopper, further, the side of the scraper in contact with the ash hopper is arranged in an arc shape.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model arranges an annular electric heating plate, an outer gear ring, a scraper and a driving mechanism in the ash hopper. During the process of dust removal by the bag dust collector, when the dust-containing gas is mixed with relatively humid air, it can not only dehumidify and dry the moist dust, but also improve the dust discharge efficiency, avoid relatively moist dust from staying in the ash hopper and breeding bacteria, causing secondary pollution to the air, and effectively improve the environmental protection of the bag dust collector when in use.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0019] Embodiment 1:

[0020] Reference Figure 1-Figure 3 An environmentally friendly bag-type dust collector comprises a bag-type dust collector body 1, and also comprises: an ash hopper 2, which is fixedly connected to the discharge port at the lower end of the bag-type dust collector body 1, and an opening and closing valve 201 is installed at the discharge pipe of the ash hopper 2; a circle of annular grooves is provided on the inner wall of the ash hopper 2; an outer gear ring 3 is rotatably connected in the annular groove; a plurality of scrapers 301 are fixedly connected to the inner side of the outer gear ring 3 at equal intervals in a circle, and slide against the inner wall of the ash hopper 2; an annular cavity is provided in the side wall of the ash hopper 2; an annular electric heating plate 202 is fixedly connected in the annular cavity; a driving mechanism for driving the outer gear ring 3 to rotate is installed on the ash hopper 2.

[0021] The driving mechanism includes a motor 4 and a gear 401. The motor 4 is fixedly connected to one side of the ash hopper 2 through a support plate. The gear 401 is fixedly connected to the output end of the motor 4. The gear 401 and the outer gear ring 3 are on the same horizontal plane. A through groove that penetrates the annular groove is provided on the side of the ash hopper 2 close to the gear 401. The side of the gear 401 close to the ash hopper 2 is located in the through groove and meshes with the outer gear ring 3.

[0022] In industrial production, when it is necessary to filter the dust-containing gas, the dust-containing gas can be passed into the bag-type dust collector body 1 through the air inlet pipe, and then the dust-containing gas will be filtered by the dust removal bag arranged inside the bag-type dust collector body 1, and then the dust will be intercepted in the bag-type dust collector body 1, and the dust-removed gas will be discharged through the exhaust pipe. When a lot of dust is filtered out in the bag-type dust collector body 1, the dust-containing exhaust gas can be stopped from being passed into the bag-type dust collector body 1, and the filtered dust will fall into the ash hopper 2, and then the opening and closing valve of the discharge pipe can be opened to discharge the dust in the dust-containing exhaust gas.

[0023] When the dust-containing exhaust gas has a certain humidity, the annular electric heating plate 202 can be started, and then the dust remaining in the ash hopper 2 can be dehumidified and dried. When the dust needs to be discharged, the opening and closing switch 201 can be opened, and the motor 4 can be started. The motor 4 will drive the outer ring gear 3 to rotate through the gear 401, and the outer ring gear 3 will drive the scraper 301 to rotate. Then the scraper 301 can scrape off the compacted dust attached to the inner wall of the ash hopper 2, so that it can be discharged through the discharge pipe together with the uncompacted dust, effectively improving the dust removal effect in the bag dust collector, avoiding some dust from staying in the bag dust collector to breed bacteria, so that the bacteria are discharged together with the gas, causing damage to the environment, and effectively improving the environmental protection of the bag dust collector.

[0024] Embodiment 2:

[0025] Reference Figure 1-Figure 3 , an environmentally friendly bag dust collector, which is basically the same as Example 1, and further: a mounting rod 303 is vertically arranged in the middle position inside the ash hopper 2, and the scraper 301 and the mounting rod 303 are fixedly connected by a connecting rod 302, and a spiral propulsion blade 304 is fixedly connected to the position inside the discharge pipe on the mounting rod 303. When the scraper 301 rotates to scrape off the dust attached to the inner wall of the ash hopper 2, the scraper 301 can drive the mounting rod 303 to rotate through the connecting rod 302, and the mounting rod 303 will drive the spiral propulsion blade 304 to rotate, thereby facilitating the transportation of dust blocked in the discharge pipe of the ash hopper 2, and effectively improving the smoothness of dust discharge.

[0026] The screw propeller blade 304 extends upward into the ash hopper 2. Figure 1 As shown, by extending the spiral propulsion blade 304 upward into the storage chamber of the ash hopper 2, when the spiral propulsion blade 304 rotates to transport the agglomerated dust downward, it is convenient to better transport the agglomerated dust, avoid large pieces of dust staying above the discharge pipe and causing blockage of the discharge pipe, and further improve the dust discharge effect.

[0027] The upper surface of the connecting rod 302 is an arc-shaped surface. By designing the upper surface of the connecting rod 302 to be an arc-shaped surface, Figure 3 As shown, when the opening and closing valve 201 is opened to discharge the dust in the ash hopper 2, part of the dust can be prevented from staying on the connecting rod 302, which effectively improves the adequacy of discharging the dust from the bag filter.

[0028] The side of the scraper 301 that is in contact with the ash hopper 2 is designed to be an arc-shaped surface. When the scraper 301 slides on the inner wall of the ash hopper 2 to scrape dust, the damage to the inner wall of the ash hopper 2 by the scraper 301 can be reduced.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
