Description

Technical Field

[0001] This utility model belongs to the technical field of pneumatic conveying devices, specifically relating to a dust removal and unloading device. Background Technology

[0002] Pneumatic conveying systems are a common material transport method, particularly suitable for long-distance transport of bulk materials. The main advantage of pneumatic conveying is its ability to transport materials through pipelines while minimizing damage to the material's shape. However, during pneumatic conveying, materials often contain a certain amount of dust and fine particles, requiring dust removal treatment of the exhaust airflow to ensure environmental cleanliness and compliance with emission standards. Simultaneously, the material unloading process also faces problems such as hopper blockage and material arching.

[0003] Currently, most dust removal devices in pneumatic conveying systems are independent dust removal components or filtration systems, typically installed separately from the storage hopper, with airflow separation and cleaning achieved through connecting pipes. However, in existing technologies, dust removal and unloading functions are mostly set up separately, and their coordination is quite complex. The existing technology, with dust removal and unloading systems as two independent devices, results in a complex overall structure, large space occupation, and inconvenient installation and maintenance.

[0004] Therefore, designing a structure that integrates dust removal and unloading functions is of great significance for improving the efficiency and stability of pneumatic conveying systems. Utility Model Content

[0005] The purpose of this utility model is to provide a dust removal and unloading device to solve the technical problems of existing pneumatic conveying systems where dust removal and unloading are two separate devices, resulting in a complex overall structure, large space occupation, and inconvenient installation and maintenance.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a dust removal and unloading device, characterized in that it includes: Dust removal components are used to remove dust and fine particles from airflow; A hopper assembly is located below the dust removal assembly, with an air inlet cut outwards at the upper part of the hopper assembly. A baffle hood is coaxially arranged inside the hopper assembly, and the air inlet cooperates with the baffle hood to block the material entering from the air inlet from impacting the dust removal bag of the dust removal assembly, and to guide the material entering from the air inlet to avoid local accumulation of material.

[0007] The dust removal component and the storage hopper component of this utility model are arranged and connected vertically to form a tight integrated structure, which can effectively remove dust from the airflow without affecting the unloading of materials.

[0008] This utility model's material storage hopper assembly is equipped with a baffle hood inside. This baffle hood is at approximately the same height as the air inlet, effectively blocking material entering from the air inlet, preventing material from impacting the filter bags, extending the service life of the filter bags inside the dust collector assembly, and improving the stability of the dust collector assembly. When material enters, the baffle hood guides it, preventing material from concentrating in one area and avoiding localized accumulation.

[0009] This utility model features an integrated dust removal and unloading structure, which is widely used in material conveying, dust removal, and unloading processes within pneumatic conveying systems.

[0010] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: the hopper assembly and the dust removal assembly are connected by a flange. The flange connection between the dust removal assembly and the hopper assembly forms a tight, integrated structure, which can effectively remove dust from the airflow without affecting material unloading; the flange connection ensures the system's airtightness and effectively prevents dust leakage.

[0011] To solve the technical problem of matching the obstruction guide with the air inlet, this utility model adopts the following technical solution: the obstruction guide is an inverted cone shape; the lower edge of the obstruction guide is lower than the bottom of the air inlet, so that the obstruction guide is located at the same height as the air inlet, thus playing the role of obstruction and airflow guidance.

[0012] Material at the bottom of the storage hopper is prone to arching during unloading due to factors such as humidity and particle size, causing the pneumatic conveying system to malfunction and affecting material flow. To solve this problem, this invention employs an air hammer at the bottom of the storage hopper assembly to prevent material arching and accumulation. The air hammer effectively prevents material arching, ensuring smooth unloading, avoiding material accumulation or blockage, and improving unloading efficiency.

[0013] To solve the technical problem of the inability to measure conveying capacity, this utility model adopts the following technical solution: a weighing unit is set on the storage hopper assembly, and the weighing units are evenly distributed on the storage hopper assembly to measure the weight of the material in the hopper in real time and calculate the conveying capacity.

[0014] To address the technical problem of not being able to determine the material capacity within the hopper assembly, this invention employs the following technical solution: a material level sensor is installed on the hopper assembly. The material level sensor monitors the material level height within the hopper; once a high-level sensor outputs a signal, material conveying is stopped.

[0015] Existing storage hopper designs lack effective maintenance channels or access ports, making rapid repairs difficult when equipment malfunctions. To address this technical problem, this invention employs the following solution: a maintenance access port is provided at the lower part of the storage hopper assembly.

[0016] Users can easily access the equipment for inspection and maintenance. The handhole design facilitates daily inspection and maintenance, reduces equipment downtime, and improves the stability of equipment operation, the reliability of the system, and its service life.

[0017] To solve the technical problem of uncontrollable unloading volume, the present invention adopts the following technical solution: the discharge port flange of the storage hopper assembly is connected to a discharge valve to control the unloading.

[0018] To address the technical problem of increasingly thick dust layers on the outer surface of filter bags in dust removal components, leading to increased equipment resistance (pressure difference) and affecting dust removal efficiency, this utility model adopts the following technical solution: the dust removal component is equipped with a pulse jet head for dust removal.

[0019] To address the technical problem of dust explosion risk within dust removal components, this utility model adopts the following technical solution: an explosion relief plate is installed on the dust removal component for safe pressure relief and to prevent explosive damage.

[0020] To address the technical problem of inconvenient maintenance of dust removal components, this utility model adopts the following technical solution: the dust removal component is equipped with an inspection door, which facilitates daily inspection and maintenance.

[0027] In one embodiment, the hopper assembly 200 and the dust removal assembly 100 are connected by a flange. A second flange 211 is provided on the upper part of the hopper 210. Specifically, the two are connected by a first flange 111 and a second flange 211. The dust removal assembly 100 and the hopper assembly 200 are connected by the first flange 111 and the second flange 211, forming a tight integral structure that can effectively remove dust from the airflow without affecting the unloading of materials. The flange connection ensures the system's airtightness and effectively prevents dust leakage.

[0028] like Figure 3 As shown, an air inlet 220 is cut outward from the upper part of the hopper assembly 200; a baffle hood 230 is coaxially arranged inside the hopper assembly 200. The air inlet and the baffle hood cooperate to block the material entering from the air inlet from hitting the dust collector bag of the dust removal assembly, and to guide the material entering from the air inlet to avoid local accumulation of material.

[0029] The storage hopper assembly 200 is equipped with a ring of baffle 230, which is located at the same height as the air inlet 220. This baffle 230 effectively blocks material entering from the air inlet 220, preventing material from impacting the filter bags, extending the service life of the filter bags inside the dust collector assembly 100, and improving the stability of the dust collector assembly 100. When material enters, the baffle 230 guides it, preventing material from concentrating in a certain area and avoiding localized accumulation.

[0030] In one embodiment, the deflector 230 is an inverted cone shape; the lower edge of the deflector 230 is lower than the bottom of the air inlet 220.

[0031] The flow deflector 230 is located on the inner wall of the hopper assembly 200, which can effectively regulate the flow of materials and prevent materials from accumulating near the inlet.

[0032] In one embodiment, an air hammer 240 is provided at the lower part of the hopper assembly 200 to prevent material from arching and accumulating within the hopper assembly. Specifically, the air hammer 240 is installed on the conical part of the hopper assembly 200.

[0036] In one embodiment, the discharge port flange 212 of the hopper assembly 200 is connected to a discharge valve. The discharge valve can be a gate valve, butterfly valve, etc., to control the discharge.

[0037] The dust removal component of this utility model is closely connected to the storage hopper component. The airflow passes through the dust removal component 100 for filtration, removing dust and fine particles, ensuring smooth airflow and effective dust removal, thereby reducing dust in the emissions and ensuring that the gas emissions during the pneumatic conveying process meet environmental protection standards.
