DETAILED DESCRIPTION

[0024] As Figs. 1-2 shown, a chemical safety feeding device, the feeding port 17 inside one side of feeding bin 1 is equipped with baffle 19, the upper end of baffle 19 is hinged with the top surface of feeding port 17, the other end is close to the bottom surface of feeding port 17, a plurality of blowing pipes 13 are arranged between the bottom surface of feeding port 17 and the end of baffle 19, the blowing pipe 13 includes the second discharge pipe 1302 parallelly arranged with the bottom surface of feeding port 17, the second discharge pipe 1302 is further equipped with the inclined high-pressure air inlet pipe 1301 in the middle part, the second discharge pipe 1302 is equipped with a pointed end at the front end, and the high-pressure air inlet pipe 1301 is communicated with the first air pump 9.

[0025] The end of material bag 14 is downward so that the pointed end of second discharge pipe 1302 is inserted into the inside of material bag 14, and the high-pressure air inlet pipe 1301 blows air to form negative pressure at the tail end of second discharge pipe 1302 to blow the material in the inside of material bag 14 into the inside of feeding bin 1.

[0026] Place the material bag 14 in the inside of feeding port 17 to ensure that the pointed end of the front end of second discharge pipe 1302 can be inserted into the inside of material bag 14. Then start the first air pump 9, blow air into the material bag through the high-pressure air inlet pipe 1301, so that the tail end of second discharge pipe 1302 forms negative pressure, thereby effectively blowing the powder material in the material bag into the inside of feeding bin 1. In this process, the baffle 19 remains closed state, close to the position of blowing pipe 13, which helps to prevent dust overflow.

[0027] By using the principle of negative pressure generated by high-pressure gas, the material can be quickly transferred from the material bag to the feeding bin, improving work efficiency. At the same time, since the baffle 19 is in a closed state during operation, the leakage of dust is effectively avoided, protecting the working environment and the health of the operator. In addition, this design can also reduce the loss during the material transfer process, and improve the cleanliness and safety of production.

[0028] In the preferred embodiment, the baffle 19 is connected to the top surface of the feeding port 17 on one side through at least one second air cylinder 18, and the two ends of the second air cylinder 18 are respectively hinged to the baffle 19 and the top surface of the feeding port 17. Since the feeding port 17 is upwardly inclined, it helps the material bag to be positioned more naturally. By controlling the second air cylinder 18 to adjust the position of the baffle 19, it can be changed from a closed state to an open state for material conveying. When ready, start the first air pump 9, and high-pressure gas is blown into the material bag 14 through the high-pressure air inlet pipe 1301, so that the tail end of the second discharge pipe 1302 forms a negative pressure, thereby blowing the material into the inside of the feeding bin 1. After the operation is completed, the baffle 19 is closed again by using the second air cylinder 18 to prevent dust leakage.

[0029] In the preferred embodiment, the feeding port 17 is upwardly inclined, and the feeding port 17 is provided with a door plate 15 at the opening position, and the door plate 15 is connected to the two sides of the feeding port 17 through the first air cylinder 16. Then by controlling the first air cylinder 16 to open the door plate 15, the material bag 14 is placed into the feeding port 17, and it is ensured that the front end of the second discharge pipe 1302 is inserted into the inside of the material bag. Then the door plate 15 is closed to ensure that it is in a closed state during the material blowing process to prevent dust leakage.

[0030] The upwardly inclined design of the feeding port 17 allows the material bag to fall under the force of gravity, reducing the difficulty and time of operation. The use of the door plate 15 in cooperation with the first air cylinder 16 not only provides convenience during material loading, but also effectively prevents dust leakage during the material blowing process, protecting the safety and cleanliness of the working environment.

[0031] In the preferred embodiment, the top of the feeding bin 1 is connected to the dust removal bin 24, the top of the dust removal bin 24 is provided with an air extraction device 21, and the inside of the dust removal bin 24 is provided with a filter cover 20, and the air inlet of the air extraction device 21 communicates with the filter cover 20.

[0032] When preparing to perform material blowing operation and expecting large dust, the air extraction device 21 in the dust removal bin 24 connected to the top of the feeding bin 1 is started in advance. As the material blowing process begins, the air extraction device 21 extracts air containing dust through the filter cover 20, so that a large amount of dust is adsorbed to the surface of the filter cover 20, effectively preventing the spread of dust in the working area. After completing the material conveying, the air extraction device 21 is closed, and the filter cover 20 is cleaned or replaced as needed to ensure the efficiency of the next use.

[0033] In the preferred embodiment, the dust removal bin 24 is also provided with a second air pump 23 on one side, and the filter cover 20 is provided with a soot blowing pipe 22 inside, which is in communication with the second air pump 23. The soot blowing pipe 22 is provided with a plurality of air holes, and the lower end of the soot blowing pipe 22 is close to the bottom of the filter cover 20, and the upper end of the soot blowing pipe 22 is close to the top of the filter cover 20.

[0034] When the dust removal bin 24 is not used and the surface of the filter cover 20 accumulates a large amount of dust that needs to be cleaned, the second air pump 23 can be opened. The air pressure generated by the second air pump 23 is transmitted through the soot blowing pipe 22. Since the soot blowing pipe 22 is provided with a plurality of air holes, and the upper and lower ends of the soot blowing pipe 22 are close to the bottom and top of the filter cover 20 respectively, the filter cover 20 can be effectively cleaned in all directions. In this way, the dust attached to the outside of the filter cover will be blown off into the feeding bin 1, thereby realizing automatic cleaning of the filter cover.

[0035] In the preferred embodiment, the feeding bin 1 is provided with a draw plate gate 25 between the feeding bin 1 and the dust removal bin 24, and the draw plate gate 25 is in sliding connection with the feeding bin 1. One side of the feeding bin 1 is provided with a third air cylinder 26, and the extension end of the third air cylinder 26 is connected with the outer end of the draw plate gate 25. When the dust removal bin 24 is not used, the position of the draw plate gate 25 can be adjusted by controlling the third air cylinder 26. The third air cylinder 26 is started to drive the draw plate gate 25 to slide along the feeding bin 1 until the passage between the feeding bin 1 and the dust removal bin 24 is completely closed. In this way, it can prevent the dust generated during the material conveying process from entering the dust removal bin 24, and also avoid the impurities in the external air from entering the feeding bin 1. After completing the material conveying or cleaning the filter cover 20, the third air cylinder 26 can be operated again according to the actual needs to open the draw plate gate 25 for subsequent processing.

[0036] In the preferred embodiment, the lower part of the feeding bin 1 is connected with the conical structure of the discharging bin 6 through the rubber ring 3, the discharging bin 6 is provided with a mesh plate 4 inside, and the outer wall of the feeding bin 1 is provided with a plurality of vibration motors 5. When the discharging process starts, the plurality of vibration motors 5 provided on the outer wall of the feeding bin 1 are started. The vibration generated by the vibration motor 5 during operation will be transmitted to the feeding bin 1, promoting the material to flow more smoothly through the connection between the rubber ring 3 and the discharging bin 6 into the discharging bin 6. Due to the existence of the rubber ring 3, this soft connection method can effectively buffer the influence of vibration on the feeding bin 1, avoiding the problem of uneven distribution of materials inside the feeding bin 1 or aggravation of equipment wear caused by vibration. Inside the discharging bin 6, the mesh plate 4 further helps to screen and control the flow speed of the material, ensuring that the material descends uniformly and stably.

[0037] In the preferred embodiment, the lower end of the discharging bin 6 is in communication with the first discharging pipe 7, the tail end of the first discharging pipe 7 is in communication with the inclined air blowing pipe 8, and the air blowing pipe 8 is in communication with the first air pump 9.

[0038] When it is needed to accelerate the material discharging from the hopper 6, the first air pump 9 is started to inject high pressure gas into the first discharging pipe 7 through the blowing pipe 8. Since the blowing pipe 8 is communicated with the tail end of the first discharging pipe 7 and the blowing pipe 8 is designed to be inclined, the injection of the high pressure gas will form a negative pressure area inside the first discharging pipe 7. The negative pressure effect promotes the material in the hopper 6 to enter and pass through the first discharging pipe 7 faster, realizing the fast discharging.

[0039] In the preferred solution, the first electric valve 10 is arranged between the first air pump 9 and the blowing pipe 8.

[0040] The third electric valve 12 is arranged between the first air pump 9 and the blowing pipe 13.

[0041] The second electric valve 11 is arranged between the first air pump 9 and the first electric valve 10 and the third electric valve 12.

[0042] When it is needed to generate the negative pressure through the blowing pipe 8 to accelerate the material discharging from the hopper 6, the second electric valve 11 and the first electric valve 10 are operated first to ensure that they are in the open state, while ensuring that the third electric valve 12 is closed. In this way, the high pressure gas generated by the first air pump 9 will directly enter the blowing pipe 8 through the first electric valve 10, thereby forming a negative pressure in the first discharging pipe 7 to promote the fast discharging of the material.

[0043] On the contrary, if it is needed to transport the material through the blowing pipe 13, the second electric valve 11 and the third electric valve 12 should be operated to be in the open state, while the first electric valve 10 is closed. At this time, the high pressure gas generated by the first air pump 9 will enter the blowing pipe 13 through the third electric valve 12 to blow the material in the material bag 14 into the feeding hopper 1 by using the high pressure gas.

[0044] The second electric valve 11 is a total valve.

[0045] The above embodiment is only the preferred technical solution of the present application, and should not be regarded as the limitation of the present application. The protection scope of the present application should be the technical solution recorded in the claims, including the equivalent replacement solution of the technical features recorded in the claims as the protection scope. That is, the equivalent replacement improvement within this range is also within the protection scope of the present application.
