Description

Technical Field

[0001] This utility model relates to the technical field of pneumatic conveyors, and in particular to a pneumatic conveyor. Background Technology

[0002] Existing flour conveyors are all positive pressure pneumatic conveyors. The connection between the flour shredder and the positive pressure pneumatic conveyor is not completely sealed, causing powder to be blown out of both the conveyor and the shredder, resulting in powder leakage and dust accumulation on the work surface, requiring cleaning. Therefore, the structure of the existing pneumatic conveyor needs further improvement. Utility Model Content

[0003] The purpose of this invention is to provide a pneumatic conveyor with negative pressure, concentrated powder conveying direction, and less powder leakage.

[0004] The purpose of this utility model is achieved as follows:

[0005] A pneumatic conveyor includes a volute, a sealing plate, a fan blade, and a motor. A feed inlet is located at the center of a first side of the volute, and a discharge outlet is located at the periphery of the volute. The second side of the volute is open, and the sealing plate is rotatably mounted on the second side of the volute, effectively closing it. The motor is mounted on the sealing plate, and the fan blade is rotatably located inside the volute. The motor shaft drives the fan blade to rotate. This pneumatic conveyor is a negative pressure conveyor, which concentrates the powder conveying direction, provides good sealing, and prevents powder from being blown out of the conveyor and the crusher, thus reducing powder leakage.

[0006] The present invention can be further improved in the following ways.

[0007] It also includes a base, with the volute mounted on the base.

[0008] The periphery of the sealing plate is bolted to the second side of the volute.

[0009] The fan blades are fixed to the motor shaft of the motor.

[0010] A first flange is provided at the discharge port for easy connection and sealing.

[0011] A second flange is provided at the feed inlet for easy connection and sealing.

[0012] The beneficial effects of this utility model are as follows:

[0013] I. This utility model of pneumatic conveyor is a negative pressure pneumatic conveyor, which concentrates the powder conveying direction, has good sealing performance, and makes it difficult for powder to be blown out of the pneumatic conveyor and the crusher, thus preventing powder leakage.

[0014] Second, the sealing plate of this utility model can be opened, making it convenient to clean the inner cavity of the volute. Attached Figure Description

[0017] Figure 3 This is a schematic diagram of the structure of the pneumatic conveyor after the sealing plate is opened. Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example 1, as Figures 1 to 3 As shown, a pneumatic conveyor includes a base 4, a volute 1, a sealing plate 2, a fan blade 5, and a motor 3. The volute 1 is mounted on the base 4. A feed inlet 11 is located at the center of the first side of the volute 1, and a discharge outlet 12 is located at the periphery of the volute 1. The second side of the volute 1 is open. The sealing plate 2 is rotatably mounted on the second side of the volute 1, and the sealing plate 2 closes the second side of the volute 1. The motor 3 is mounted on the sealing plate 2, and the fan blade 5 is rotatably mounted inside the volute 1. The motor shaft of the motor 3 drives the fan blade 5 to rotate.

[0020] This is a more specific technical solution of the present invention.

[0021] The periphery of the sealing plate 2 is bolted to the second side of the volute 1.

[0022] The fan blade is fixed on the motor shaft of motor 3.

[0023] A first flange 13 is provided at the discharge port 12.

[0024] A second flange 14 is provided at the feed inlet 11.

[0025] The working principle of this utility model is as follows:

[0026] The motor shaft of motor 3 drives the fan blade to rotate, which generates negative pressure in the inner cavity of volute 1. Powder is drawn into the inner cavity of volute 1 from feed port 11, and then the powder is discharged from the inner cavity of volute 1 from discharge port 12.
