Description

Technical Field

[0001] This utility model relates to the field of pneumatic feeding auxiliary components, specifically to an anti-blocking and anti-mixing device for pneumatic material conveying equipment. Background Technology

[0002] Transporting materials from storage tanks to receiving tanks is a crucial step in automated mechanical processing. In the actual production of silica bricks, during the process of raw materials moving through the workshop, powder is usually first transferred from the delivered ton bags to the storage tanks. Then, a pipeline transports various raw materials from the storage tanks to multiple different receiving tanks. However, because different raw materials have different particle sizes and specific gravities, their settling distances and speeds in the pipelines are also different, which can easily lead to material mixing and pipeline blockage. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-blocking and anti-mixing device for pneumatic material conveying equipment in order to solve the above-mentioned problems. Anti-mixing and anti-blocking components are assembled in the pneumatic conveying pipes corresponding to each receiving hopper. At the same time, the anti-mixing and anti-blocking components are provided with a backflush valve body on the outside of the inlet end of the pneumatic conveying pipe near the outlet of the distribution tee, and a backflush valve body is also provided on the outside of the outlet end of the pneumatic conveying pipe. Then, by supplying air to the backflush valve bodies at both ends of the pneumatic conveying pipe through the air storage tank, the conveying angle during the material conveying process can be changed, as detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This utility model provides an anti-blocking and anti-mixing device for a pneumatic material conveying equipment, including a blower body, a feeding bin body, a receiving bin body, and a pneumatic conveying pipe. The blower body is connected to the feeding bin body through the air supply pipe, and the feeding pipe of the feeding bin body extends outward and is provided with multiple sections. Adjacent sections of the feeding pipe are connected by a material distribution tee, and the outermost end of the material distribution tee is sealed and plugged.

[0006] Each of the material distribution tees is fixedly connected to the air conveying pipe at its upper outlet position, and the material outlet of the air conveying pipe is fixedly connected to the material receiving hopper body through a material receiving pipe.

[0007] All external locations of the air conveying pipes are equipped with anti-mixing and anti-blocking components to prevent material mixing and pipe blockage.

[0008] Preferably, the anti-mixing and anti-clogging components each include a backflush valve body, an auxiliary blowing valve body, and a gas storage tank body. The backflush valve body is provided on the outside of the feed end of the air conveying pipe near the outlet of the material distribution tee. The backflush valve body is also provided on the outside of the discharge end of the air conveying pipe. Several backflush valve bodies and auxiliary blowing valve bodies are installed on the outside of the middle section of the air conveying pipe. The backflush valve body and the auxiliary blowing valve body are all connected to the gas storage tank body through pipelines.

[0009] Preferably, the inner diameter of both the backflush valve body and the blow-assisted valve body is at least 12 mm.

[0010] Preferably, in the direction from the feed end to the discharge end of the air conveying pipe, the angle between the backflush valve body and the air conveying pipe is an acute angle, and the angle between the auxiliary blow valve body and the air conveying pipe is an obtuse angle.

[0011] Preferably, the purging valve body and the backflushing valve body are both spaced apart outside the air delivery duct.

[0012] Preferably, both the backflush valve body and the blow-assisted valve body are equipped with electrically controlled valves for independent opening and closing, and the electrically controlled valves are electrically connected to the main control unit.

[0013] Preferably, the main control unit is a PLC main unit.

[0014] The aforementioned anti-clogging and anti-mixing device for pneumatic material conveying equipment, specifically in the process of using pneumatically conveyed raw materials, involves the following: Each pneumatic conveying pipe corresponding to the receiving hopper is equipped with an anti-mixing and anti-clogging component. Furthermore, the anti-clogging and anti-mixing component has a backflush valve body located outside the inlet end of the pneumatic conveying pipe near the outlet of the distribution tee, and another backflush valve body is located outside the outlet end of the pneumatic conveying pipe. By supplying air through the air tank to the backflush valve bodies at both ends of the pneumatic conveying pipe, the material conveying process can be altered. The conveying angle during the process is adjusted to prevent raw materials from remaining in the air conveying pipe and causing mixing. Moreover, since the anti-mixing and anti-clogging component is equipped with several backflush valves and auxiliary blow valves on the outside of the middle section of the air conveying pipe, when the material is fed, the backflush valves in the middle section of the air conveying pipe can blow air to clean the remaining material in the air conveying pipe. At the same time, when the air conveying pipe is blocked, the backflush valves and auxiliary blow valves can alternately blow air to use high-pressure air to backflush or assist in blowing to clear the blockage of the air conveying pipe.

[0015] The beneficial effects are as follows: 1. This utility model is equipped with anti-mixing and anti-blocking components in the air conveying pipes corresponding to each receiving hopper body. At the same time, the anti-mixing and anti-blocking components are equipped with back-blowing valves at the inlet end of the air conveying pipe near the outlet of the distribution tee and at the outlet end of the air conveying pipe. Then, by supplying air to the back-blowing valves at both ends of the air conveying pipe through the air storage tank body, the conveying angle during the raw material conveying process can be changed, thereby preventing the raw material from remaining in the air conveying pipe and causing mixing.

[0016] 2. The anti-mixing and anti-clogging component is equipped with several backflush valves and auxiliary airflush valves on the outside of the middle section of the air conveying pipe. When the material is fed, the backflush valves in the middle section of the air conveying pipe can blow air to clean the residual material in the air conveying pipe. At the same time, when the air conveying pipe is blocked, the backflush valves and auxiliary airflush valves can blow air alternately to use high-pressure air to backflush or assist in blowing to clear the air conveying pipe.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] See Figure 1As shown, this utility model provides an anti-blocking and anti-mixing device for pneumatic material conveying equipment, including a blower body 4, a feeding hopper body 5, a receiving hopper body 1, and a pneumatic conveying pipe 2. The blower body 4 is connected to the feeding hopper body 5 through a blower pipe 401. The feeding pipe 6 of the feeding hopper body 5 extends outward and is provided with multiple sections. Adjacent sections of the feeding pipe 6 are connected by a distribution tee 7, and the outermost end of the distribution tee 7 is sealed. The upper outlet of each distribution tee 7 is fixedly connected to the pneumatic conveying pipe 2, and the outlet end of the pneumatic conveying pipe 2 is fixedly connected to the receiving hopper body 1 through a receiving pipe 101. Anti-mixing and anti-blocking components 3 are combined and provided on the outer side of the pneumatic conveying pipe 2 to prevent mixing and pipe blockage. Specifically, the anti-mixing and anti-blocking components 3 include a backflush valve body 301, a blow-assisted valve body 303, and an air storage tank body 304. The inlet end of the pneumatic conveying pipe 2 is near the distribution tee 7. A backflush valve body 301 is installed outside the outlet of the 7-channel, and a backflush valve body 301 is also installed outside the discharge end of the air conveying pipe 2. Several backflush valve bodies 301 and auxiliary blowing valve bodies 303 are installed outside the middle section of the air conveying pipe 2. Both the backflush valve bodies 301 and auxiliary blowing valve bodies 303 are connected to the air storage tank body 304 through pipelines. With this configuration, firstly, by supplying air to the backflush valve bodies 301 at both ends of the air conveying pipe 2 through the air storage tank body 304, the conveying angle during the material conveying process can be changed, thereby preventing the material from remaining in the air conveying pipe 2 and causing mixing. At the same time, when the material is finished, the backflush valve bodies 301 in the middle section of the air conveying pipe 2 can be used to blow air back to clean the remaining material in the air conveying pipe 2. Moreover, when the air conveying pipe 2 is blocked, the backflush valve bodies 301 and auxiliary blowing valve bodies 303 can be used to blow air back or assist in clearing the air conveying pipe 2 by alternating air blowing.

[0023] See Figure 1 As shown, the anti-clogging and anti-mixing component 3 has been optimized as follows: the inner diameter of both the backflush valve body 301 and the auxiliary blowing valve body 303 is at least 12mm to ensure that both have the required valve diameter, thus improving performance. Optionally, in the direction from the inlet to the outlet of the pneumatic conveying pipe 2, the angle between the backflush valve body 301 and the pneumatic conveying pipe 2 is acute, and the angle between the auxiliary blowing valve body 303 and the pneumatic conveying pipe 2 is obtuse. This arrangement ensures that the angles of both the backflush valve body 301 and the auxiliary blowing valve body 303 achieve the desired performance.

[0024] Optionally, the purging valve body 303 and the backflushing valve body 301 are spaced apart on the outside of the air delivery duct 2. This arrangement allows for a predictable pattern in the combination and arrangement of the purging valve body 303 and the backflushing valve body 301, facilitating later maintenance. Also optionally, both the backflushing valve body 301 and the purging valve body 303 are equipped with independently controllable electrically controlled valves 302 on their exterior. These electrically controlled valves 302 are electrically connected to the main control unit 305, which is a PLC main unit. This arrangement allows operators to centrally control all the electrically controlled valves 302 using the main control unit 305, facilitating overall monitoring.

[0025] With the above structure, specifically in the process of using pneumatic conveying of raw materials, anti-mixing and anti-clogging components 3 are assembled in the pneumatic conveying pipes 2 corresponding to each receiving hopper body 1. At the same time, anti-mixing and anti-clogging components 3 are equipped with backflush valve bodies 301 on the outside of the inlet end of the pneumatic conveying pipe 2 near the outlet of the distribution tee 7, and also on the outside of the outlet end of the pneumatic conveying pipe 2. Then, by supplying air to the backflush valve bodies 301 at both ends of the pneumatic conveying pipe 2 through the air storage tank body 304, the conveying angle during the raw material conveying process can be changed. This prevents raw materials from remaining in the air conveying pipe 2 and causing material mixing. Furthermore, since the anti-mixing and anti-clogging component 3 is equipped with several backflush valves 301 and auxiliary blow valves 303 on the outside of the middle section of the air conveying pipe 2, when the material feeding is completed, the backflush valves 301 in the middle section of the air conveying pipe 2 can blow air back to clean the remaining material in the air conveying pipe 2. At the same time, when the air conveying pipe 2 is blocked, the backflush valves 301 and auxiliary blow valves 303 can blow air alternately to use high-pressure air backflush or auxiliary blow to clear the blockage of the air conveying pipe 2.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
