Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically to a dust collector inlet and outlet air structure. Background Technology

[0002] In industrial production, dust collection equipment is widely used for dust control. Common dust collectors use a fan to generate negative pressure, drawing dust-laden gas into the dust collection duct. After being filtered by internal dust collection components, clean air is discharged. However, in actual operation, especially for dust deposited on the ground or equipment surface, relying solely on suction often creates blind spots, making it difficult to effectively entrain and lift dust directly below the dust collection duct or in a specific direction, resulting in reduced dust collection efficiency. Utility Model Content

[0003] Technical objective: To address the shortcomings of existing dust removal equipment, this utility model discloses a dust collector inlet and outlet structure that can draw back a portion of the purified gas and blow it towards the area to be dusted through an adjustable outlet pipe, thereby blowing up the dust and facilitating more efficient intake by the dust removal duct.

[0004] Technical solution: To achieve the above technical objectives, the present invention adopts the following technical solution: A dust collector inlet and outlet structure includes a dust collector duct, which is connected to a fan via a pipe. A dust collector assembly is installed along the connection path between the dust collector duct and the fan to remove dust from the dust-laden gas entering the dust collector duct. A return air duct is installed at the outlet end of the fan. An outlet duct connected to the return air duct is installed on the outer wall of the dust collector duct. The outlet duct has a hollow structure and is embedded in the outer wall of the dust collector duct. Several adjustable-angle outlet pipes are installed on the outlet duct.

[0005] Preferably, the air outlet pipe of this utility model is evenly distributed along the circumference of the dust removal duct and is concentrically set with the dust removal duct. As the dust removal duct moves, it blows up the dust in the area directly opposite the dust removal duct and is then sucked up by the dust removal duct.

[0006] Preferably, the air outlet pipe and the air outlet tube of this utility model are connected by a flexible hose. A drive ring is slidably sleeved on the air outlet tube. The side of the drive ring near the air outlet pipe is hinged to the air outlet pipe by a connecting rod. The side of the drive ring away from the air outlet pipe is connected to a linear power source. The linear power source drives the drive ring to move back and forth to synchronously adjust the air outlet direction of the air outlet pipe.

[0007] Preferably, in this invention, the dust removal duct and the air outlet duct are fitted together at the contacting wall surface through a concave-convex structure. The concave part is provided on the dust removal duct, and the convex part is provided on the air outlet duct. An air duct is opened on the convex part to connect with the air outlet duct.

[0008] Preferably, a control valve is provided at the connection between the air outlet duct and the return air duct of this utility model.

[0009] Beneficial effects: The dust collector inlet and outlet structure disclosed in this utility model has the following beneficial effects: 1. This utility model achieves a "blowing and suction combination" dust removal method by setting an air outlet duct with an adjustable angle air outlet duct on the outer wall of the dust removal duct and using the purified gas from the fan outlet as the air source; the airflow blown out by the air outlet duct can lift up the dust that has been deposited or is in a dead corner, so that it enters the effective dust suction range of the dust removal duct, which significantly improves the dust removal efficiency.

[0010] 2. This utility model, through the cooperation of a drive ring, connecting rod and linear power source, can realize the synchronous and precise adjustment of the air outlet angle of multiple air outlet pipes, adapt to the dust control needs of different distances and positions, and is easy to operate and highly automated.

[0011] 3. The dust removal duct and the exhaust duct of this utility model are connected by a concave-convex interlocking structure, which is compact, stable and convenient for duct layout and overall movement. Attached Figure Description

Detailed Implementation

[0014] Reference will now be made in detail to embodiments of the present disclosure, one or more of which are set forth herein. Each embodiment and example is provided by way of explanation of the apparatus, composition, and materials of the present disclosure, and not by way of limitation. Rather, the following description provides convenient illustrations for implementing exemplary embodiments of the present disclosure. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the teachings of the present disclosure without departing from the scope or spirit of the present disclosure.

[0015] like Figure 1The diagram shows the inlet and outlet air structure of a dust collector provided by this utility model. It mainly includes a dust collection duct 1, a fan (not shown), and dust collection components (not shown). The dust collection components are typically installed in the pipeline between the duct 1 and the fan, such as filters, a return air pipeline 2, an outlet air duct 3, and several outlet air pipes 4. After the fan starts, dust-laden gas is drawn into the dust collection duct 1, purified by the dust collection components in the pipeline, and then discharged by the fan. Part of the purified gas is returned to the outlet air duct 3 through the return air pipeline 2 at the fan outlet end.

[0016] like Figure 1 and Figure 2 As shown, the exhaust duct 3 used in this invention has a ring-shaped hollow structure and is fixedly fitted onto the outer wall of the dust collection duct 1 through a concave-convex fitting method. Multiple interfaces are evenly distributed along the circumference of the exhaust duct 3, and each interface is connected to an exhaust pipe 4 via a flexible hose 5. The outlet direction of the exhaust pipe 4 is adjustable. To achieve synchronous adjustment of multiple exhaust pipes 4, a drive ring 6 that can slide along its axial direction is fitted onto the exhaust duct 3. The drive ring 6 is guided by a guide rail pre-set on the exhaust duct 3. The body of each exhaust pipe 4 is hinged to the side of the drive ring 6 via a connecting rod 7. A linear power source 8 (such as an electric push rod or cylinder fixedly installed on the support of the exhaust duct 3 or the dust collection duct 1) is connected to one side of the drive ring 6. When the linear power source 8 extends or retracts, it will push the drive ring 6 to move axially along the air outlet duct 3, and then drive all the air outlet pipes 4 to swing synchronously around the connection point with the hose 5 through the connecting rod 7, thereby changing the blowing angle and blowing up dust in different areas. At the same time, an air outlet groove can be set on the side wall of the air outlet pipe 4. The air outlet groove 4 is tangentially set along the circumference of the air outlet pipe 4 to form an effect similar to an air wall, so as to reduce the dispersion of dust.

[0017] To facilitate rapid assembly and ensure a tight fit between the dust collection duct 1 and the outlet duct 3, an annular groove is provided on the outer wall of the dust collection duct 1 at the connection point with the outlet duct 3, and a matching annular protrusion is provided on the inner wall of the outlet duct 3, allowing the two to fit together. Inside the protruding portion of the outlet duct 3, annularly distributed air ducts 9 are machined, which are connected to the return air duct 2 and used to distribute gas to the various hoses 5 and the outlet duct 4.

[0018] A control valve 10 is installed at the connection between the return air duct 2 and the outlet air duct 3 to control the on / off state and flow rate of the return gas.

[0019] In operation, this invention adjusts the tilt angle of the outlet duct 4 using the linear power source 8, based on the deposition of the dust, to precisely direct the airflow towards the area requiring dust removal. Opening the control valve 10 allows some of the purified gas to be blown out at high speed from the outlet duct 4, raising dust from the ground or equipment surface. Simultaneously, the dust collection duct 1 generates strong suction under the action of the fan, rapidly drawing in the raised dust, thus achieving efficient dust removal. This structure is particularly suitable for mobile or fixed dust removal scenarios such as sweepers and fixed-point dust collection equipment, ensuring effective dust removal of surface-attached dust.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
