Description

Technical Field

[0001] This utility model belongs to the field of centrifuge technology, and in particular relates to a scraper centrifuge receiving hopper blowing device. Background Technology

[0002] In the field of centrifuge technology, scraper centrifuges, as an important type of filtration centrifugation equipment, are widely used in various industrial production processes. Their continuous operation and intermittent discharge effectively improve production efficiency. The working cycle of a scraper centrifuge typically includes multiple steps such as feeding, mother liquor removal, filter cake washing, washing liquid removal, and unloading. However, in certain industries, such as when processing filter cakes with low moisture content and high water absorption, the unloading process often faces a thorny problem: material easily accumulates on the surface of the receiving hopper.

[0003] As production continues, material gradually accumulates in the receiving hopper. If it is not cleaned in a timely manner each time, it will not only affect the normal operation of the equipment, but may even cause complete blockage of the discharge port, forcing production to stop. Therefore, the current method of cleaning the blockage is to stop the machine and open the hopper. This cleaning method is not only labor-intensive, but also seriously reduces the overall production efficiency. Utility Model Content

[0004] This invention proposes a scraper centrifuge receiving hopper blowing device that can solve the problem of material residue accumulation in the receiving hopper after unloading.

[0005] The present invention provides a scraper centrifuge receiving hopper blowing device, which is installed on the side wall of the receiving hopper and includes an air inlet chamber and an external compressed air duct. The air inlet chamber is arranged on the outer side wall of the receiving hopper and is connected to the duct. An installation port is opened on the side wall of the receiving hopper within the range of the air inlet chamber. A spray pipe is connected to the installation port through a universal ball joint. The end of the spray pipe located in the air inlet chamber is connected to an air collecting tube, and the end located inside the receiving hopper is connected to a nozzle.

[0006] Beneficial Effects: This invention features a sealed air inlet chamber on the outer wall of the receiving hopper. Compressed air is introduced through an air duct and then sprayed out from the nozzle along the spray pipe to purge the material inside the hopper. The entire process does not require stopping the machine or opening the hopper door; residual material can be directly blown out of the hopper. Furthermore, to ensure purging at any angle within the hopper, the spray pipe is connected to the hopper via a universal ball joint. The angle can be adjusted before machine startup or controlled during use (a cotton thread can be connected to the spray pipe and led out from the hopper for angle control). To increase air intake speed, an air collector is installed at the end of the spray pipe located within the air inlet chamber, facilitating rapid entry of compressed air into the spray pipe. This ensures timely cleaning of residues after each use of the receiving hopper, preventing material from becoming damp and sticking together to form old deposits. In summary, this invention fundamentally solves the problem of material residue accumulation in the receiving hopper.

[0007] Furthermore, the air inlet chamber has an air duct interface, which is fixed with a connector for connecting the air duct. The connector has a valve that opens unidirectionally from the outside to the inside to prevent debris and dust in the air inlet chamber from entering the air duct and causing blockage.

[0008] Furthermore, the air collecting duct is conical, with its small end connected to the nozzle and its large end facing into the air inlet chamber, thereby achieving rapid airflow.

[0009] Furthermore, the outer wall of the receiving hopper is provided with a pipe clamp for fixing the air duct to prevent the air duct lines from becoming messy.

[0010] Furthermore, the valve is a rubber valve, which is low in cost and can efficiently achieve unidirectional control. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of a scraper centrifuge receiving hopper blowing device according to the present invention. Detailed Implementation

[0012] The following detailed description illustrates the specific implementation method:

[0013] The reference numerals in the accompanying drawings of the instruction manual include: 1. receiving hopper, 2. air inlet, 3. connector, 3-1. one-way valve, 4. nozzle, 4-1. air collection tube, 4-2. nozzle, 4-3. universal ball joint, 5. air duct, 6. pipe clamp.

[0014] A scraper centrifuge receiving hopper blowing device is installed on the outer side wall of the centrifuge receiving hopper 1. It includes a semi-circular arc plate. The axial wall of the semi-circular arc plate is fixed to the outer side wall of the receiving hopper 1. The two ends of the semi-circular arc plate are closed by semi-circular plates. The semi-circular arc plate, the semi-circular plates and the outer side wall of the receiving hopper 1 enclose an air inlet chamber 2.

[0015] The semi-circular plate has a duct interface on its wall, and a connector 3 is connected to the duct interface. The connector 3 has an internal thread on its outer side, and the end of the duct 5 has an external thread, and the two are connected by threads. The connector 3 has a one-way valve 3-1 that opens from the outside to the inside, which can ensure that compressed air enters the air inlet chamber 2, while debris and dust in the air inlet chamber 2 cannot enter the duct 5.

[0016] An installation port is provided on the side wall of the receiving hopper 1 within the air inlet chamber 2. A universal ball joint 4-3 is installed in the installation port. The universal ball joint 4-3 is equipped with a nozzle 4 (the middle section of the nozzle 4 is coaxially connected to the ball joint). The nozzle 4 connects the air inlet chamber 2 and the receiving hopper 1. A nozzle 4-2 is installed on the end of the nozzle 4 located in the receiving hopper 1. A conical air collecting tube 4-1 is provided on the end of the nozzle 4 located in the air inlet chamber 2. The small end of the air collecting tube 4-1 is fixed to the nozzle 4, and the large end faces into the air inlet chamber 2.

[0017] A pipe clamp 6 is welded to the outer wall of the centrifuge receiving hopper 1 to fix the compressor air duct 5.

[0018] In this utility model, the air duct 5 is connected to an external compressed air source. Compressed air is blown into the air inlet chamber 2 along the connector 3, then passes through the air collection duct 4-1 and the nozzle 4, and finally sprays out from the nozzle 4-2 into the receiving hopper 1 to purge the material remaining in the receiving hopper 1. Since the nozzle 4 is connected to the side wall of the receiving hopper 1 by a universal ball joint, the angle of the nozzle 4 can be manually adjusted after unloading to control the purging angle of the compressed air.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed by this utility model should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
