Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically to a dust removal device for the preparation of composite additives that is easy to clean. Background Technology

[0002] Composite additives are premixed granules produced by mixing various additives, such as antioxidants and acid scavengers, in a specific formula ratio using a cold extrusion process. They consist entirely of additives and contain no resin. The preparation of composite additives requires steps such as material pretreatment, mixing, grinding and molding, curing, and post-treatment. During the mixing and reaction of the raw materials, stirring is necessary. However, the impact of the falling raw materials on the stirring blades in the mixer, as well as the airflow generated within the mixer, causes some powder to rise into the air, forming dust. Therefore, dust removal equipment is often required to control this dust.

[0003] Existing dust removal equipment generally uses filters to filter dust. However, the filters are usually rigidly connected to the dust removal equipment, making it inconvenient to clean, collect, and reuse the raw material dust attached to the filters. This not only easily causes filter clogging but also leads to waste of raw materials. Utility Model Content

[0004] The present invention aims to provide a dust removal device for the preparation of composite additives that is easy to clean, and can clean, collect and reuse dust adhering to the filter screen during the dust removal process.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A dust removal device for the preparation of composite additives that is easy to clean includes:

[0007] A reaction vessel, on which a support is fixedly connected, and a dust collection box is installed on the support. One side of the dust collection box is connected to the reaction vessel through a conduit, and a negative pressure machine is installed on the other side.

[0008] The mounting slot is located on the upper and lower sides of the inner wall of the dust collector. An elastic rod is fixed on the inner wall of the mounting slot. The free end of the elastic rod is fixedly connected to a mounting frame. A filter screen is detachably installed inside the mounting frame.

[0009] The missing gear is rotatably connected to the side wall of the dust collector. A rack is meshed below the missing gear and slidably connected to the inner wall of the dust collector. An elastic rod is fixedly connected to the end of the rack away from the filter screen. When the missing gear rotates, it will drive the rack to reciprocate and impact the mounting frame.

[0010] Based on the above technical solution, its operating principle and the resulting technical effects are as follows:

[0011] When preparing composite additives, raw materials need to be added to the reaction vessel and stirred. During the stirring process, a large amount of dust is generated, forming fly ash. At this time, the negative pressure machine is started to generate negative pressure airflow, which can draw the fly ash above the reaction vessel into the dust collection box for centralized treatment, preventing fly ash from overflowing and affecting the health of workers or causing environmental pollution. During the dust removal process, the motor is started to drive one of the missing gears to rotate, and the two missing gears rotate synchronously through the set synchronous pulley and synchronous belt. When the missing gear rotates, it will mesh with the rack below, driving the rack to move and interact with the elastic rod. During the compression process, as the missing gear continues to rotate, it disengages from the rack. At this point, the rack resets under the elastic force of the elastic rod, causing it to impact the mounting frame. This causes the filter screen to vibrate, and the rack reciprocates by impacting the mounting frame, thus cleaning the dust adhering to the surface of the filter screen. The dust falls through the dust guide plate into the dust collection chamber. After the raw materials are mixed, the protective door can be opened to remove the raw material dust from the dust collection chamber for reuse. It should be noted that when the filter screen needs to be disassembled and replaced, it can be directly removed from the mounting frame.

[0012] In a preferred embodiment, the present invention can be further configured such that a protective door is rotatably connected to the side wall of the dust collection box, and a sealing strip is provided between the protective door and the dust collection box.

[0013] In a preferred embodiment, the present invention can be further configured such that the mounting bracket is slidably connected within the mounting groove, and the mounting bracket and the filter screen are tightly engaged.

[0014] In a preferred embodiment, the present invention can be further configured such that: a dust collection chamber is provided at the bottom of the inner wall of the dust collection box, and a dust guide plate is fixedly connected to the side wall of the dust collection chamber, with one side of the dust guide plate being set as an inclined surface and the other side being attached to the bottom of the filter screen.

[0015] In a preferred embodiment, the present invention can be further configured such that the number of filters is set to two, namely a coarse filter and a fine filter.

[0016] In a preferred embodiment, the present invention can be further configured such that: the number of missing gears is two, both of which are rotatably connected to the side wall of the dust collector via bearings, and a synchronous pulley and a synchronous belt are provided between the two missing gears.

[0017] In a preferred embodiment, the present invention can be further configured such that: a guide frame is slidably connected to the side wall of the rack, and the guide frame is fixedly connected to the inner wall of the dust collection box, and baffles are fixedly connected to both ends of the rack.

[0018] In a preferred embodiment, the present invention can be further configured such that the second elastic rod is fixedly installed on the inner wall of the dust collection box via a connecting plate.

[0019] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0020] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0021] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0022] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0023] A movable connection refers to a connection in which parts or components are fixed but have relative motion.

[0024] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0025] This utility model, through the coordinated structure of a missing gear, rack, elastic rod one, and elastic rod two, can drive the rack to impact the mounting frame, thereby causing the filter screen to vibrate. In this way, the rack reciprocates and impacts the mounting frame, which can clean the dust adhering to the surface of the filter screen and make it fall into the dust collection chamber for easy secondary use.

[0032] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.

[0033] Based on the concept of this application, combined with Figures 1 to 4 This document describes an embodiment of a dust removal device for the preparation of composite additives that is easy to clean. Specifically, this dust removal device is constructed as an integral structure, comprising three components: a reaction vessel 1, a mounting groove 5, and a gear 9. Through the interaction of the gear 9, rack 10, elastic rod 6, and elastic rod 11, the rack 10 is driven to impact the mounting frame 7, causing the filter screen 8 to vibrate. This reciprocating impact of the rack 10 against the mounting frame 7 cleans the dust adhering to the surface of the filter screen 8, causing it to fall into the dust collection chamber 12 for later reuse.

[0034] Combination Figures 1-4 As shown, the dust removal device for the preparation of composite additives that is easy to clean, provided by this utility model, includes:

[0035] The reactor 1 has a support 2 fixedly connected to its side wall. A dust collector 3 is installed on the support 2. One side of the dust collector 3 is connected to the reactor 1 through a conduit 16, and a negative pressure machine 4 is installed on the other side.

[0036] Mounting slot 5 is located on the upper and lower sides of the inner wall of dust collection box 3. An elastic rod 6 is fixed on the inner wall of mounting slot 5. The free end of the elastic rod 6 is fixedly connected to a mounting bracket 7. A filter screen 8 is detachably installed inside the mounting bracket 7.

[0037] Gear 9 is missing. Gear 9 is rotatably connected to the side wall of dust collection box 3. Gear 10 is meshed below gear 9. Gear 10 is slidably connected to the inner wall of dust collection box 3. And the end of gear 10 away from filter screen 8 is fixedly connected to elastic rod 11. When gear 9 rotates, it will drive gear 10 to reciprocate and impact the mounting frame 7.

[0038] Regarding the technical solution of this embodiment, a protective door is rotatably connected to the side wall of the dust collection box 3, and a sealing strip is provided between the protective door and the dust collection box 3. In actual use, opening the protective door facilitates the disassembly and replacement of the filter screen 8, while the sealing strip enhances the sealing performance between the protective door and the dust collection box 3, preventing dust from overflowing.

[0039] Regarding the technical solution of this embodiment, the mounting bracket 7 is slidably connected in the mounting groove 5, and the mounting bracket 7 and the filter screen 8 are tightly engaged. The mounting groove 5 is set as a rectangular groove, and the elastic rod 6 in the mounting groove 5 is specifically set as a spring rod, which is mainly used to provide elastic potential energy to the mounting bracket 7 to drive it to reset. The elastic rod 6 can only move in a straight line. The tight engagement between the mounting bracket 7 and the filter screen 8 can enhance the sealing performance between the two and prevent dust leakage.

[0040] It should be noted that when the mounting bracket 7 moves within the mounting slot 5, the bottom of the mounting bracket 7 fits tightly against the mounting slot 5, which can effectively prevent dust leakage.

[0041] Regarding the technical solution of this embodiment, a dust collection chamber 12 is provided at the bottom of the inner wall of the dust collection box 3. A dust guide plate 13 is fixedly connected to the side wall of the dust collection chamber 12. One side of the dust guide plate 13 is set as an inclined surface, and the other side is attached to the bottom of the filter screen 8. In actual use, when cleaning the dust on the filter screen 8, the dust on the filter screen 8 will fall downward into the dust collection chamber 12 for centralized treatment. The dust guide plate 13 can be used to make the falling dust slide into the dust collection chamber 12.

[0042] In this embodiment, the number of filters 8 is set to two, namely a coarse filter 8 and a fine filter 8. By using the two filters 8, dust can be effectively filtered, avoiding the generation of flying dust during the preparation of composite additives, which could affect the health of workers or cause environmental pollution.

[0043] In this embodiment, there are two missing gears 9. Both missing gears 9 are rotatably connected to the side wall of the dust collector 3 via bearings. A synchronous pulley 17 and a synchronous belt 18 are provided between the two missing gears 9. A motor 19 is fixedly connected to the end of one of the missing gears 9. The motor 19 is installed on the outer side wall of the dust collector 3 and is powered by an external power source. Starting the motor 19 can drive one of the missing gears 9 to rotate. The synchronous pulley 17 and the synchronous belt 18 make the two missing gears 9 rotate synchronously. When the missing gear 9 rotates, it will mesh with the rack 10 below and drive the rack 10 to move and squeeze the elastic rod 6. As the missing gear 9 continues to rotate, the missing gear 9 will disengage from the rack 10. At this time, the rack 10 will reset under the elastic force of the elastic rod 6, causing the rack 10 to impact the mounting frame 7, thereby causing the filter screen 8 to vibrate. In this way, the rack 10 reciprocates to impact the mounting frame 7, which can clean the dust adhering to the surface of the filter screen 8.

[0044] Regarding the technical solution of this embodiment, a guide frame 14 is slidably connected to the side wall of the rack 10, and the guide frame 14 is fixedly connected to the inner wall of the dust collection box 3. Furthermore, baffles 15 are fixedly connected to both ends of the rack 10. The guide frame 14 is provided to support and guide the rack 10 when it moves, and the baffles 15 are provided to prevent the rack 10 from separating from the guide frame 14.

[0045] Regarding the technical solution of this embodiment, the second elastic rod 11 is fixedly installed on the inner wall of the dust collection box 3 through the connecting plate. The second elastic rod 11 is specifically configured as a spring rod. The second elastic rod 11 is mainly used to provide elastic force to the rack 10 and drive it to reset.

[0046] Specifically, when preparing the composite additive, raw materials need to be added to the reaction vessel 1 and stirred. During the stirring process, a large amount of dust is generated from the raw materials, forming fly ash. At this time, the negative pressure machine 4 is started to generate negative pressure airflow, which can draw the fly ash above the reaction vessel 1 into the dust collection box 3 for centralized treatment, preventing the fly ash from overflowing and affecting the health of the staff or causing environmental pollution. During the dust removal process, the motor 19 is started to drive one of the missing gears 9 to rotate, and the two missing gears 9 rotate synchronously through the synchronous pulley 17 and the synchronous belt 18. When the missing gear 9 rotates, it will mesh with the rack 10 below, and drive the rack 10 to move and move the elastic rod 6. As the extruded material is pressed, the missing gear 9 continues to rotate, and it will disengage from the rack 10. At this time, the rack 10 will be reset under the elastic force of the elastic rod 6, causing the rack 10 to impact the mounting frame 7, thereby causing the filter screen 8 to vibrate. In this way, the rack 10 reciprocates and impacts the mounting frame 7, which can clean the dust adhering to the surface of the filter screen 8. After the dust falls, it will fall into the dust collection chamber 12 through the dust guide plate 13. After the raw materials are mixed, the protective door can be opened to remove the raw material dust in the dust collection chamber 12 for reuse. It should be noted that when the filter screen 8 needs to be disassembled and replaced, it can be directly removed from the mounting frame 7.

[0047] The dust removal device for preparing composite additives that is easy to clean, provided by this utility model, will be further described below with reference to the accompanying drawings and embodiments.

[0048] A dust removal device for the preparation of composite additives that is easy to clean includes:

[0049] The reactor 1 has a support 2 fixedly connected to its side wall. A dust collector 3 is installed on the support 2. One side of the dust collector 3 is connected to the reactor 1 through a conduit 16, and a negative pressure machine 4 is installed on the other side.

[0050] Mounting slot 5 is located on the upper and lower sides of the inner wall of dust collection box 3. An elastic rod 6 is fixed on the inner wall of mounting slot 5. The free end of the elastic rod 6 is fixedly connected to a mounting bracket 7. A filter screen 8 is detachably installed inside the mounting bracket 7.

[0051] Gear 9 is missing. Gear 9 is rotatably connected to the side wall of dust collection box 3. Gear 10 is meshed below gear 9. Gear 10 is slidably connected to the inner wall of dust collection box 3. And the end of gear 10 away from filter screen 8 is fixedly connected to elastic rod 11. When gear 9 rotates, it will drive gear 10 to reciprocate and impact the mounting frame 7.

[0052] The working principle and usage process of this utility model are as follows: When preparing the composite additive, raw materials need to be added to the reaction vessel 1 for stirring. During the stirring process, a large amount of dust will be generated from the raw materials, forming flying dust. At this time, the negative pressure machine 4 is started to generate negative pressure airflow, which can suck the flying dust above the reaction vessel 1 into the dust collection box 3 for centralized treatment, avoiding the flying dust from overflowing and affecting the health of the staff or causing environmental pollution. During the dust removal process, the motor 19 is started to drive one of the missing gears 9 to rotate, and the two missing gears 9 rotate synchronously through the synchronous pulley 17 and the synchronous belt 18. When the missing gear 9 rotates, it will mesh with the rack 10 below, and drive the rack 10 to move and... The elastic rod 6 is squeezed, and as the missing gear 9 continues to rotate, the missing gear 9 will disengage from the rack 10. At this time, the rack 10 will reset under the elastic force of the elastic rod 6, causing the rack 10 to impact the mounting frame 7, thereby causing the filter screen 8 to vibrate. In this way, the rack 10 reciprocates and impacts the mounting frame 7, which can clean the dust adhering to the surface of the filter screen 8. After the dust falls, it will fall into the dust collection chamber 12 through the dust guide plate 13. After the raw materials are mixed, the protective door can be opened to remove the raw material dust in the dust collection chamber 12 for reuse. It should be noted that when the filter screen 8 needs to be disassembled and replaced, the filter screen 8 can be directly removed from the mounting frame 7.
