Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically a powder conveying device for chemical production. Background Technology

[0002] Chemical powders refer to raw materials in powder form used in chemical operations. Due to the characteristics of powders such as being easy to fly, easy to clump, and some being flammable, the transportation process must take into account efficiency, safety, environmental protection, and material stability.

[0003] Chinese Patent Publication No. CN 222118042 U discloses a chemical powder conveying device, including a housing for conveying operations. Inside the housing, there is a conveying component that can adjust the feed diameter of the auger according to the raw material demand to increase the unit conveying capacity. At one end of the housing, there is also a stirring component for stirring the chemical powder. At the other end of the housing, above the dust collection hood, there is also a baffle component for controlling the material feeding operation.

[0004] The aforementioned chemical powder conveying device uses an auger to transfer the powder; however, chemical powders are generally small in volume, and some powders are prone to clumping and sticking together. During the transportation of the powder, some powder will remain on the inner wall of the shell of the aforementioned chemical powder conveying device, and cleaning the inner wall of the shell of the aforementioned chemical powder conveying device is very inconvenient. It is necessary to stop the conveying operation and disassemble the conveying device, which reduces the efficiency of powder transportation. Utility Model Content

[0005] The purpose of this utility model is to provide a powder conveying device for chemical production, which uses an air conveying component to blow air into the silo and uses pneumatic force to transport the powder. The air conveying component can also clean the residue on the silo, the silo body and the inner wall of the conveying component, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A powder conveying device for chemical production, comprising:

[0008] A silo pump assembly is used to convey powder materials. A silo is located above the silo pump assembly. The silo pump assembly is connected to the conveying assembly.

[0009] The gas delivery assembly, located on one side of the silo pump assembly, is connected to both the silo pump assembly and the delivery assembly.

[0010] The aforementioned silo pump assembly includes a silo body, on the top of which is equipped with a feed valve and at the bottom of which is a discharge port; a main air inlet is located on one side of the upper end of the silo body and a secondary air inlet is located on one side of the lower end.

[0011] The gas delivery assembly includes a gas delivery pipe, one end of which is connected to the gas pump unit and the other end is fixedly connected to the main pipe; the end of the main pipe away from the gas delivery pipe is fixedly connected to the main air inlet.

[0012] The middle section of the gas pipeline is fixedly connected to a T-junction. One end of the T-junction is fixedly connected to a secondary pipe, the end of the secondary pipe away from the T-junction is fixedly connected to a flexible hose, and the end of the flexible hose away from the secondary pipe is fixedly connected to a secondary air inlet.

[0013] As a further technical solution of this utility model, an exhaust port is fixedly connected to the upper end of the silo body, and the end of the exhaust port away from the silo body is fixedly connected to an exhaust pipe; the end of the exhaust pipe away from the exhaust port is fixedly connected to the silo, and the exhaust pipe communicates with the internal space of the silo.

[0014] As a further technical solution of this utility model, the conveying component includes a connecting pipe one, one end of which is fixedly connected to the discharge port and the other end of which is fixedly connected to a connecting pipe two; a cleaning port is provided at the top of the middle section of the connecting pipe two.

[0015] As a further technical solution of this utility model, the middle section of the gas transmission pipe is fixedly connected to a T-junction 2, one end of which is fixedly connected to a secondary pipe 2; the end of the secondary pipe 2 away from the T-junction 2 is fixedly connected to a flexible hose 2; and the end of the flexible hose 2 away from the secondary pipe 2 is fixedly connected to the cleaning port.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, after opening the manual discharge valve and the feed valve, the powder in the hopper will fall into the hopper body. When the powder accumulated in the hopper body reaches the predetermined height (below the main air inlet), the manual discharge valve and the feed valve are closed. High-pressure gas enters the hopper body through the main air inlet and pushes the powder in the hopper body into the connecting pipe, thereby realizing the transfer of the powder. During the transportation of the powder, it can effectively prevent the powder from scattering and also prevent the powder from contacting the external environment.

[0018] 2. In this utility model, pneumatic valves are installed on both the exhaust port and the secondary pipe 2. When using gas to transport powder, the pneumatic valves close the exhaust port and the secondary pipe 2. At this time, the gas will not enter the silo through the exhaust pipe, nor will it enter the connecting pipe 2 through the hose 2. This can prevent the air pressure in the silo from dropping, ensure that the airflow can push the powder, and prevent the airflow from becoming turbulent. After the powder is transported, the pneumatic valves on the exhaust port and the secondary pipe 2 are opened and closed at the same time. Then the airflow can enter the silo and the connecting pipe 2, so that the airflow can clean the powder residue on the inner walls of the silo, the connecting pipe 1, and the connecting pipe 2.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-8 In this embodiment of the utility model, a powder conveying device for chemical production includes...

[0031] The silo pump assembly 2 is used to convey powder and has a silo 1 on top; the silo pump assembly 2 is connected to the conveying assembly 4.

[0032] Gas delivery assembly 5, located on one side of the silo pump assembly 2, is connected to the silo pump assembly 2 and the delivery assembly 4.

[0033] The silo pump assembly 2 includes a silo body 21, with a feed valve 23 installed on the top of the silo body 21 and a discharge port 27 at the bottom of the silo body 21; a main air inlet 25 is provided on one side of the upper end of the silo body 21 and a secondary air inlet 26 is provided on one side of the lower end; the top of the feed valve 23 is fixedly connected to a manual discharge valve 3, and the side of the manual discharge valve 3 away from the feed valve 23 is fixedly connected to the bottom opening of the silo 1.

[0034] The gas delivery assembly 5 includes a gas delivery pipe 51, one end of which is connected to the gas pump unit and the other end is fixedly connected to the main pipe 54; the end of the main pipe 54 away from the gas delivery pipe 51 is fixedly connected to the main air inlet 25.

[0035] The middle section of the gas supply pipe 51 is fixedly connected to a tee 52. One end of the tee 52 is fixedly connected to the secondary pipe 55. The end of the secondary pipe 55 away from the tee 52 is fixedly connected to the hose 59. The end of the hose 59 away from the secondary pipe 55 is fixedly connected to the secondary air inlet 26.

[0036] By adopting the above technical solution, after opening the manual discharge valve 3 and the feed valve 23, the powder in the hopper 1 will fall into the hopper body 21. When the powder accumulated in the hopper body 21 reaches the predetermined height (below the main air inlet 25), the manual discharge valve 3 and the feed valve 23 are closed. High-pressure gas enters the hopper body 21 through the main air inlet 25 and pushes the powder in the hopper body 21 into the connecting pipe 41, thereby realizing the transfer of the powder. During the transportation of the powder, it can effectively prevent the powder from scattering and also prevent the powder from contacting the external environment.

[0037] In this embodiment, an exhaust port 24 is fixedly connected to the upper end of the silo body 21, and the end of the exhaust port 24 away from the silo body 21 is fixedly connected to the exhaust pipe 6; the end of the exhaust pipe 6 away from the exhaust port 24 is fixedly connected to the silo 1, and the exhaust pipe 6 communicates with the internal space of the silo 1.

[0038] The conveying assembly 4 includes a first connecting pipe 41, one end of which is fixedly connected to the discharge port 27 and the other end of which is fixedly connected to a second connecting pipe 42; a cleaning port 45 is provided at the top of the middle section of the second connecting pipe 42; the end of the second connecting pipe 42 away from the first connecting pipe 41 is fixedly connected to a valve 43, and the end of the valve 43 away from the second connecting pipe 42 is fixedly connected to the end of the conveying pipe 44.

[0039] The middle section of the gas supply pipe 51 is fixedly connected to a tee 2 53, one end of which is fixedly connected to a secondary pipe 2 56; the end of the secondary pipe 2 56 away from the tee 2 53 is fixedly connected to a hose 2 57; the end of the hose 2 57 away from the secondary pipe 2 56 is fixedly connected to the cleaning port 45; filters 58 for filtering impurities in the air are installed on the secondary pipe 1 55, secondary pipe 2 56 and main pipe 54.

[0040] By adopting the above technical solution, pneumatic valves are installed on both the exhaust port 24 and the secondary pipe 56. When using gas to transport powder, the pneumatic valves close the exhaust port 24 and the secondary pipe 56. At this time, the gas will not enter the silo 1 through the exhaust pipe 6, nor will it enter the connecting pipe 42 through the hose 57. This can prevent the air pressure in the silo 21 from dropping, ensuring that the airflow can push the powder, and also prevent the airflow from becoming turbulent. After the powder is transported, the pneumatic valves on the exhaust port 24 and the secondary pipe 56 are opened, and the valve 43 is closed at the same time. Then the airflow can enter the silo 1 and the connecting pipe 42, so that the airflow can clean the powder residue on the inner walls of the silo 1, the connecting pipe 41, and the connecting pipe 42.

[0041] The working principle of this utility model is as follows: After opening the manual discharge valve 3 and the feed valve 23, the powder in the hopper 1 will fall into the hopper body 21. When the powder accumulated in the hopper body 21 reaches the predetermined height (below the main air inlet 25), the manual discharge valve 3 and the feed valve 23 are closed. High-pressure gas enters the hopper body 21 through the main air inlet 25 and pushes the powder in the hopper body 21 into the connecting pipe 41, thereby realizing the transfer of the powder. During the transportation of the powder, it can effectively prevent the powder from scattering and also prevent the powder from contacting the external environment.

[0042] Both the exhaust port 24 and the secondary pipe 56 are equipped with pneumatic valves. When using gas to transport powder, the pneumatic valves close the exhaust port 24 and the secondary pipe 56. At this time, the gas will not enter the silo 1 through the exhaust pipe 6, nor will it enter the connecting pipe 42 through the hose 57. This can prevent the air pressure in the silo 21 from dropping, ensuring that the airflow can push the powder, and also prevent the airflow from becoming turbulent. After the powder is transported, the pneumatic valves on the exhaust port 24 and the secondary pipe 56 are opened, and the valve 43 is closed at the same time. Then the airflow can enter the silo 1 and the connecting pipe 42, so that the airflow can clean the powder residue on the inner walls of the silo 1, the connecting pipe 41, and the connecting pipe 42.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
