Description

Technical Field

[0001] This application relates to the technical field of dust collection equipment, and in particular to a dust collection device for a feeding port. Background Technology

[0002] The related technology, disclosed in CN209865578U, describes a dust removal device for a feeding inlet, belonging to the field of feed production. It includes a shell, an air inlet, and an air outlet. A dust hopper is connected to the bottom of the shell. A partition slides vertically inside the shell, forming a clean air chamber between the partition and the top wall of the shell. The air outlet connects to the clean air chamber. Several ventilation holes are provided on the partition. Filter bags connected to the ventilation holes are fixedly mounted on the bottom wall of the partition. A blowpipe is fixedly mounted inside the clean air chamber, with nozzles connected to the blowpipe and facing the ventilation holes. An air tank connected to the blowpipe is fixedly mounted outside the shell. A pull rod slides vertically through the top wall of the shell, and a drive assembly is provided on the shell to raise and lower the pull rod. When cleaning the filter bags, the drive assembly raises the pull rod, causing the partition to rise vertically, reducing the distance between the nozzles and the ventilation holes, effectively increasing the amount of air entering the filter bags and improving the cleaning effect.

[0003] In view of the design characteristics of the dust collection device at the feeding port in the above-mentioned technology, the inventors found that the existing dust collection device adopts a planar vertical ordinary pulse dust collection device, which is not ideal in terms of dust overflow and treatment effect. Utility Model Content

[0004] In order to address the problem that existing dust collection devices at the feeding port are designed with the characteristics of their own, the inventors have found that the existing dust collection devices use a planar vertical ordinary pulse dust collection device, which is not ideal in terms of dust overflow and treatment effect. This application provides a dust collection device at the feeding port.

[0005] The dust collection device for the feeding port provided in this application adopts the following technical solution: it includes a support platform, a dust collector body fixedly installed on the upper surface of the support platform, an air inlet port installed on the support platform and adapted to the air inlet of the dust collector body, filter bag cavities evenly arranged in the inner cavity of the dust collector body, a high-pressure fan arranged relative to the filter bag cavity, an exhaust port installed on the dust collector body, a guardrail installed on the upper surface of the support platform and relative to the dust collector body, and a ladder fixedly installed on one side of the support platform and connected to the guardrail.

[0006] The inner cavity of the support platform is sequentially configured as a dust suction chamber and a dust collection chamber in a direction away from the dust collector body.

[0007] By adopting the above technical solution, when the high-pressure blower is working, it creates a negative pressure state in the inner cavity of the dust collector body. The outside air captures the dust overflowing during the unloading process through the dust suction chamber on the support platform and enters the dust collector body. The dust is then filtered by the filter bag chamber inside the dust collector body, and the filtered air is discharged through the exhaust port. The impurities generated by the dust collector body during the dust removal process fall into the dust collection chamber of the support platform due to their own weight. The staff can clean the impurities collected in the dust collection chamber periodically.

[0008] Optionally, a sealing ring is provided at the connection between the support platform and the dust collector body, and the sealing ring is arranged circumferentially around the outer periphery of the dust collector body.

[0009] By adopting the above technical solution, the sealing of the connection between the dust collector body and the support platform is effectively guaranteed, preventing dust from leaking out from the connection.

[0010] Optionally, the dust inlet surface of the dust suction chamber is configured as an arc-shaped structure, and dust suction ports with the same curvature are evenly arranged on the dust inlet surface.

[0011] By adopting the above technical solution, the arc-shaped surface design increases the dust collection area. The main purpose of this design is to increase the air suction area of ​​the dust collector body, thereby improving the dust collection efficiency. Traditional dust collector bodies usually adopt a planar structure design, which has a limited air suction area and is difficult to meet the needs of large-scale dust treatment.

[0012] Optionally, a cleaning door is hinged to the front end face of the dust collection chamber, and the outer periphery of the cleaning door abuts against the outer periphery of the dust collection chamber.

[0013] By adopting the above technical solution, it is convenient for staff to open the cleaning door to clean the impurities in the dust collection chamber.

[0014] Optionally, a sealing strip is provided at the connection between the outer periphery of the cleaning door and the dust collection chamber, and the sealing strip is bonded to the outer periphery of the cleaning door by a polymer adhesive.

[0015] By adopting the above technical solution, the sealing strip effectively ensures the airtightness of the connection between the cleaning door and the dust collection chamber, and effectively prevents dust from leaking out of the dust collection chamber.

[0016] Optionally, the front end face of the cleaning door is uniformly provided with support columns, and the upper end face of the support columns is fixedly connected to the lowest point of the arc of the dust suction chamber.

[0017] By adopting the above technical solution, the support column can easily support the lower end of the support platform and can also limit the front end of the cleaning door to prevent the cleaning door from opening due to negative pressure and causing dust leakage, thereby effectively ensuring the dust removal efficiency of the dust collector body.

[0018] In summary, this application has the following beneficial technical effects:

[0019] 1. By placing the dust collector body above the support platform, it is convenient for workers to unload materials and operate on residual materials above the support platform. At the same time, it is more conducive to the dust collector to collect and treat the dust overflowing during the unloading process, and it can also increase the dust collection capacity.

[0020] 2. When the high-pressure blower is working, it creates a negative pressure state in the inner cavity of the dust collector body. Outside air captures the dust overflowing during the unloading process through the dust suction chamber on the support platform and enters the dust collector body. The dust is then filtered by the filter bag chamber inside the dust collector body, and the filtered air is discharged through the exhaust port. The impurities generated by the dust collector body during the dust removal process fall into the dust collection chamber of the support platform due to their own weight. The staff can clean the impurities collected in the dust collection chamber periodically.

[0021] 3. By setting the dust inlet surface of the dust collection chamber to an arc-shaped structure, and uniformly setting dust inlets with the same curvature on the dust inlet surface, the arc-shaped platform increases the dust collection area. The main purpose of this design is to increase the air suction area of ​​the dust collector body, thereby improving the dust collection efficiency. Traditional dust collector bodies usually adopt a planar structure design, which has a limited air suction area and is difficult to meet the needs of large-scale dust treatment.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This application discloses a dust collection device for a feeding port, including a support platform 1, a dust collector body 2 fixedly mounted on the upper surface of the support platform 1, an air inlet port 10 mounted on the support platform 1 and adapted to the air inlet of the dust collector body 2, filter bag cavities 4 evenly distributed within the inner cavity of the dust collector body 2, a high-pressure fan 3 disposed relative to the filter bag cavities 4, an exhaust port 21 disposed on the dust collector body 2, a protective railing 51 disposed on the upper surface of the support platform 1 and relative to the dust collector body 2, and a device fixedly mounted on one side of the support platform 1 and connected to the protective railing 51. In this utility model, when the high-pressure blower 3 is working, it creates a negative pressure state in the inner cavity of the dust collector body 2. The outside air captures the dust overflowing during the unloading process through the dust suction chamber on the support platform 1 and enters the dust collector body 2. The dust is filtered by the filter bag chamber 4 inside the dust collector body 2, and the filtered air is discharged through the exhaust port 21. The impurities generated by the dust collector body 2 during the dust removal process fall into the dust collection chamber 12 of the support platform 1 due to their own weight. The staff can clean the impurities collected in the dust collection chamber 12 regularly.

[0029] Please refer to details. Figure 1 and Figure 2 It includes a support platform 1 and a dust collector body 2 fixedly installed on the upper surface of the support platform 1. A sealing ring is provided at the connection between the support platform 1 and the dust collector body 2. The sealing ring is arranged circumferentially around the outer periphery of the dust collector body 2, which effectively ensures the sealing of the connection between the dust collector body 2 and the support platform 1 and prevents dust from leaking out from the connection.

[0030] Please refer to details. Figure 1 and Figure 3 The dust collector consists of an air inlet port 10 on the support platform 1 that matches the air inlet of the dust collector body 2; filter bag chambers 4 evenly distributed inside the dust collector body 2; a high-pressure blower 3 positioned relative to the filter bag chambers 4; and an exhaust port 21 on the dust collector body 2. When the high-pressure blower 3 is working, it creates a negative pressure state inside the dust collector body 2. Outside air is drawn into the dust collector body 2 through the suction chamber on the support platform 1, capturing dust overflowing during unloading. The dust is then filtered by the filter bag chambers 4 inside the dust collector body 2, and the filtered air is discharged through the exhaust port 21. Impurities generated during the dust collection process fall into the dust collection chamber 12 on the support platform 1 due to their own weight. The dust collector body 2 only needs to periodically clean the collected impurities in the dust collection chamber 12.

[0031] Please refer to details. Figure 1 and Figure 2The system includes a guardrail 51 installed on the upper surface of the support platform 1 and relative to the dust collector body 2, and a ladder 52 fixed on one side of the support platform 1 and connected to the guardrail 51; this facilitates workers to access the support platform 1 via the ladder to inspect the dust collector body 2.

[0032] Please refer to the following for details: Figure 3 and Figure 4 The inner cavity of the support platform 1 is arranged in sequence with a dust suction chamber and a dust collection chamber 12 in the direction away from the dust collector body 2. The dust inlet surface of the dust suction chamber is set with an arc structure, and dust suction ports 11 with the same curvature are evenly arranged on the dust inlet surface. The arc surface design increases the dust suction area. The main purpose of this design is to increase the air suction area of ​​the dust collector body 2, thereby improving the dust removal efficiency. The traditional dust collector body 2 usually adopts a planar structure design, which has a limited air suction area and is difficult to meet the needs of large-scale dust treatment.

[0033] Please refer to the following for details: Figure 3 and Figure 4 The front end face of the dust collection chamber 12 is hinged with a cleaning door 122. The outer periphery of the cleaning door 122 is set against the outer periphery of the dust collection chamber 12, so that the staff can open the cleaning door 122 to clean the impurities in the dust collection chamber 12.

[0034] Please refer to the following for details: Figure 1 and Figure 3 A sealing strip is provided at the connection between the outer periphery of the cleaning door 122 and the dust collection chamber 12. The sealing strip is bonded to the outer periphery of the cleaning door 122 by a polymer adhesive. The sealing strip effectively ensures the airtightness of the connection between the cleaning door 122 and the dust collection chamber 12, and effectively prevents dust from leaking out of the dust collection chamber 12.

[0035] Please refer to the following for details: Figure 3 and Figure 4 The front end face of the cleaning door 122 is evenly provided with support columns 121. The upper end face of the support column 121 is fixedly connected to the lowest point of the arc of the dust collection chamber. The support column 121 can support the lower end face of the support platform 1 and limit the front end face of the cleaning door 122 to prevent the cleaning door 122 from opening due to negative pressure and causing dust leakage, thereby effectively ensuring the dust removal efficiency of the dust collector body 2.

[0036] The implementation principle of the dust collection device at the feeding port in this embodiment is as follows: When in use, the high-pressure blower 3 creates a negative pressure state in the inner cavity of the dust collector body 2. The outside air captures the dust overflowing during the unloading process through the dust suction chamber on the support platform 1 and enters the electrostatic precipitator body 2. The dust is filtered by the filter bag chamber 4 inside the dust collector body 2, and the filtered air is discharged through the exhaust port 21. The impurities generated by the dust collector body 2 during the dust removal process fall into the dust collection chamber 12 of the support platform 1 due to their own weight. The staff can clean the impurities collected in the dust collection chamber 12 regularly.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
