Description

Technical Field

[0001] This utility model relates to the field of pneumatic conveying devices, and more specifically, to a pneumatic conveying and supplying device for mineral powder. Background Technology

[0002] In the field of pneumatic conveying of mineral powder, the pneumatic conveying supply device is a high-efficiency, environmentally friendly, and flexible mineral powder conveying equipment. Its working principle is based on high-pressure airflow propelling mineral powder through the pipeline. However, in the traditional mineral powder conveying process, due to the small size of the mineral powder particles and the agitation effect of the airflow, dust often escapes at the air outlet, which not only pollutes the external environment of the equipment but also poses a potential threat to the health of the operators.

[0003] For example, the utility model patent (application number: 202021682408.9) discloses a "pneumatic conveying system for basalt stone powder," the description of which shows: a first storage tank with a feed inlet penetrating its upper side, and a second storage tank connected to its lower side via a first discharge outlet; the second storage tank connected to a conveying pipe via a second discharge outlet; a first electric valve fixed inside both the second and first discharge outlets; an exhaust pipe penetrating the left outer wall of the second storage tank, and an air inlet pipe penetrating the right inner wall of the second storage tank; a crushing and stirring assembly fixed to the first storage tank; and a guiding assembly fixed to the second storage tank. This pneumatic conveying system for basalt stone powder includes a crushing and stirring assembly, where the crushing blades can further crush the basalt stone powder. The stirring rod and crushing blades also prevent the basalt stone powder from accumulating at the first discharge outlet. This patent demonstrates the deficiencies of the existing technology.

[0004] Therefore, we have made improvements to this and proposed a pneumatic conveying and supply device for mineral powder. Utility Model Content

[0005] The purpose of this utility model is to address the problem that dust can escape from the air outlet during the conveying of mineral powder, causing pollution to the environment outside the equipment.

[0006] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a pneumatic conveying and supply device for mineral powder, including a pneumatic conveying mechanism. A storage tank is located at the rear end of the pneumatic conveying mechanism. An air outlet channel communicating with the interior of the storage tank is located at the top end of the storage tank. A blocking component is located behind the air outlet channel. Protective components are located on both sides of the blocking component. A water storage component is located at the top end of the blocking component. A control component is located at the rear end of the water storage component. The control component controls the water flow inside the recovery component to the front end of the blocking component, cooperating with the blocking component to capture dust. A recovery component is located at the bottom end of the blocking component, and a circulation component is located on one side of the recovery component.

[0007] As a preferred technical solution of this application, the pneumatic conveying mechanism includes a body and a supply pipe at the rear end of the body, the end of the supply pipe being fixedly connected to the top of the storage tank and communicating with the interior of the storage tank.

[0008] As a preferred technical solution of this application, the blocking member includes a blocking plate located behind the air outlet channel, the blocking plate being used to block the airflow discharged from inside the air outlet channel.

[0009] As a preferred technical solution of this application, the water storage component includes a water tank fixed to the top of the baffle plate, and the bottom of the water tank has an outlet that communicates with the inside of the water tank.

[0010] As a preferred technical solution of this application, the control component includes a fixing plate fixed below the rear end of the water tank, a closing plate slidably provided at the top of the fixing plate, the front end of the closing plate extending through the water tank into the interior of the water tank, and a connecting cylinder fixedly provided at the top of the closing plate behind the water tank, with a lead screw threaded inside the connecting cylinder.

[0011] As a preferred technical solution of this application, the recycling assembly includes a recycling bin fixed to the bottom of the baffle plate, a connecting frame is slidably provided inside the recycling bin, one side of the connecting frame extends through the recycling bin to the outside of the recycling bin, and a barrier net is fixedly provided below the inside of the connecting frame.

[0012] As a preferred technical solution of this application, the two protective components include two side plates respectively fixed to both sides of the barrier plate, and an arc-shaped groove is provided on the front of the opposite side of the two side plates.

[0013] As a preferred technical solution of this application, the circulation component includes a water pump located on one side of the recycling bin, an installation pipe fixedly provided on one side of the recycling bin and communicating with the inside of the recycling bin, the end of the installation pipe communicating with the input end of the water pump, and a connecting pipe fixedly provided at the output end of the water pump, the end of the connecting pipe communicating with and fixedly connected to the inside of the water tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] 1. By setting up a blocking component and a water storage component, the control component enables the water storage component to form a water curtain at the front end of the blocking component. This causes the dust in the gas flowing out of the outlet channel to be adhered by the water and then fall into the recycling component for recycling. This improves the safety and environmental protection during transportation and solves the problem in the existing technology that dust will escape from the air outlet and cause pollution to the outside environment of the equipment during the transportation of mineral powder.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] Example 1

[0029] Please refer to Figure 1 and Figure 2 A pneumatic conveying and supply device for mineral powder includes a pneumatic conveying mechanism 2. A storage tank 1 is located at the rear end of the pneumatic conveying mechanism 2. An air outlet channel 11, communicating with the interior of the storage tank 1, is located at the top of the storage tank 1. One end of the air outlet channel 11 faces the rear end. A blocking component is located behind the air outlet channel 11, with protective components on both sides. A water storage component is located at the top of the blocking component. A control component 6 is located at the rear end of the water storage component. The control component 6 controls the water flow inside a recovery component 7 to the front end of the blocking component, working with the blocking component to capture dust, thereby preventing dust pollution of the external environment. A recovery component 7 is located at the bottom of the blocking component, used to recover the captured water and dust. A circulation component 8 is located on one side of the recovery component 7, used to transfer the water recovered by the recovery component 7 back to the water storage component for recycling, thereby avoiding water waste.

[0030] Furthermore, such as Figure 1 As shown, the pneumatic conveying mechanism 2 includes a body 21 and a supply pipe 22 at the rear end of the body 21. By starting the body 21, the valve at the bottom of the tank in the body 21 is opened, causing the mineral powder inside to fall downward into the supply pipe 22. The fan in the body 21 is started to make the airflow flow from the front end to the rear end of the supply pipe 22. The airflow carries the mineral powder that has fallen into the supply pipe 22, and the mineral powder is transported along the path inside the supply pipe 22 to the storage tank 1, supplying mineral powder to the storage tank 1. The end of the supply pipe 22 is fixedly connected to the top of the storage tank 1 and communicates with the inside of the storage tank 1.

[0031] Furthermore, such as Figure 1 and Figure 2 As shown, the blocking component includes a baffle plate 31 located behind the air outlet channel 11. The baffle plate 31 is used to block the airflow discharged from the inside of the air outlet channel 11. The baffle plate 31 is a certain distance away from the outlet of the air outlet channel 11, so that the gas still has enough space to be discharged when the baffle plate 31 blocks the airflow.

[0032] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown, the water storage component includes a water tank 51 fixed to the top of the baffle plate 31. The top of the water tank 51 is provided with a water inlet 53 communicating with the inside of the water tank 51, and the bottom of the water tank 51 is provided with a water outlet 52 communicating with the inside of the water tank 51. The water outlet 52 is located at the front end of the baffle plate 31. The water inside the water tank 51 flows downward through the water outlet 52, forming a water curtain on the baffle and the protective component. Through the adhesion of the water and the action of gravity, the dust particles in the airflow are captured.

[0033] Furthermore, such as Figure 2 and Figure 3 As shown, the control component 6 includes a fixed plate 54 fixed below the rear end of the water tank 51. A closing plate 64 is slidably provided at the top of the fixed plate 54. The closing plate 64 is used to block the water outlet 52 to prevent water from flowing out of the water outlet 52. The front end of the closing plate 64 extends through the water tank 51 into the interior of the water tank 51. The closing plate 64 contacts the bottom end of the interior of the water tank 51. By setting a rubber pad on the outside of the closing plate 64, the position where the closing plate 64 passes through the water tank 51 is sealed to prevent water from flowing out of its interior and also to prevent water from flowing out of the water outlet 52. A connecting cylinder 63 is fixedly provided at the top of the closing plate 64 behind the water tank 51. A lead screw 62 is threaded inside the connecting cylinder 63. A motor 61 is fixedly provided at the top of the fixed plate 54. The output end of the motor 61 is fixedly connected to the rear end of the lead screw 62. Starting the motor 61 drives the lead screw 62 to rotate, causing the connecting cylinder 63 to drive the closing plate 64 to move back and forth through the thread, thereby controlling the opening and closing of the water outlet 52.

[0034] Example 2

[0035] The pneumatic conveying and supply device for mineral powder provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 and Figure 5 As shown, the recycling assembly 7 includes a recycling box 71 fixed to the bottom of the baffle plate 31. A connecting frame 72 is slidably provided inside the recycling box 71. A handle is fixed on one side of the connecting frame 72. By pulling the handle, the connecting frame 72 can be pulled outward, making it easy to pull out the connecting frame 72 and collect the dust carried down by the water inside the recycling frame 72. It is also easy to clean. One side of the connecting frame 72 extends through the recycling box 71 to the outside of the recycling box 71. A barrier net 73 is fixedly provided at the bottom inside the connecting frame 72. The barrier net 73 blocks and filters the dust in the water, causing the water to fall into the recycling box 71 below the connecting frame 72, while the dust is inside the connecting frame 72.

[0036] Furthermore, such as Figure 2 and Figure 4As shown, the two protective components include two side plates 41 fixed to both sides of the baffle plate 31. Each side plate 41 has an arc-shaped groove 42 on the front of its opposite side. The shape of the water outlet 52 matches the arc-shaped groove 42 and the front end of the baffle plate 31, allowing water to flow inside the arc-shaped groove 42 and at the front end of the baffle plate 31. The gas discharged from the outlet of the air passage 11 first contacts the baffle plate 31. Combined with the water flowing out of the water outlet 52, the dust particles in the airflow are captured by the adhesion and gravity of the water. Then the airflow is dispersed to both sides and blocked by the side plates 41 to increase the contact opportunity between the dust and water in the airflow. The arc shape of the arc-shaped groove 42 guides the airflow back to the middle position. At this time, the water blown to both sides by the airflow can return to the middle and fall into the recycling component 7 for recycling. This prevents the water from being blown to the surroundings when the airflow impact force is too large, thus saving resources.

[0037] Example 3

[0038] The pneumatic conveying and supply devices for mineral powder provided in Examples 1 and 2 have been further optimized, such as... Figure 2 As shown, the circulation component 8 includes a water pump 81 located on one side of the recycling bin 71. When the water pump 81 is started, it transports water from inside the recycling bin 71 to the inside of the water tank 51. An installation pipe 82 communicating with the inside of the recycling bin 71 is fixedly provided on one side of the recycling bin 71. The inside of the recycling bin 71 is connected to the input end of the water pump 81 through the installation pipe 82. The end of the installation pipe 82 is connected to the input end of the water pump 81. A connecting pipe 83 is fixedly provided at the output end of the water pump 81. The inside of the water tank 51 is connected to the output end of the water pump 81 through the connecting pipe 83. The end of the connecting pipe 83 is connected to and fixedly connected to the inside of the water tank 51.

[0039] The process of using the pneumatic conveying and supply device for mineral powder provided by this utility model is as follows:

[0040] When conveying dust, the valve at the bottom of the tank in the machine body 21 is opened by controlling the machine body 21, and the mineral powder falls into the supply pipe 22. The fan in the machine body 21 is started to make the airflow flow inside the supply pipe 22, which drives the mineral powder in the supply pipe 22 to the inside of the storage tank 1. Then the airflow is discharged from the outlet of the air outlet channel 11. At this time, the motor 61 is started to make the lead screw 62 drive the connecting cylinder 63 and the closing plate 64 to move backward through the thread, opening the water outlet 52. The water in the water tank 51 flows through the water outlet 52 and forms a water curtain on the baffle plate 31 and the arc groove 42.

[0041] The airflow discharged from the outlet of the air outlet 11 is blocked by the baffle plate 31. Then, the dust in the airflow is captured by the adhesion of water and carried to the connecting frame 72 inside the recycling box 71. The dust is filtered and stored inside the connecting frame 72 by the barrier net 73.

[0042] Water inside the recycling bin 71 flows to the water pump 81 through the installation pipe 82. The water pump 81 is started to transport the water inside the recycling bin 71 through the barrier net 73 to the water tank 51 for recycling.
