Description

TECHNICAL FIELD

[0001] The present application relates to the field of material transfer, in particular to a safe automatic feeding mechanism for barrel-shaped chemical raw materials. BACKGROUND

[0002] Some chemical raw materials are loaded in plastic chemical barrels. When adding chemical raw materials to the inside of processing equipment in a chemical plant, the barrels are lifted and poured into the feeding port of the processing equipment.

[0003] A barrel-shaped chemical raw material automatic feeding mechanism is disclosed in Chinese patent document (CN117566457B). By adopting the structure of the first guide frame and the second guide frame, the mobile platform and the barrel can be guided and transported, so that the barrel is lifted and transported to the vicinity of the filling port at the top of the processing equipment. The mobile platform is guided by the spiral part, so that the barrel is turned over to pour the raw materials. Thus, the automatic feeding of the raw materials is realized. This method is simple to operate and does not require manual pushing of the barrel to pour the raw materials, greatly simplifying the operation and improving the work efficiency. At the same time, the safety is effectively improved, and the operation difficulty is reduced.

[0004] In the patent document, the mobile platform and the barrel are moved upward by winding the plate chain, and then the mobile platform is guided by the first guide frame and the second guide frame, and the lifting mechanism turns over the mobile platform and the barrel to pour the materials. However, the lifting mechanism is connected to the mobile platform and the barrel by the plate chain, and the plate chain is a flexible transmission component. When the mobile platform and the barrel are moved horizontally by the plate chain, it is impossible to avoid the lateral error of the plate chain. Moreover, the mobile platform and the barrel filled with materials are heavy, and frequent horizontal displacement of the mobile platform and the barrel by the plate chain can easily cause the pins in the middle of the plate chain to loosen, affecting the actual service life of the plate chain and causing great safety hazards when the plate chain moves with the barrel.

[0043] Working principle: in the initial state, the sleeve frame 8 is located directly above the supporting plate 3, at this time the material barrel is placed in the inside of the sleeve frame 8, which can just be placed on the supporting plate 3, at this time the worker deflects the rotating disc 15 through the push rod 18, and pushes the positioning pin seat 17 through the arc-shaped through slot 16, so that the plurality of top rods 12 can clamp the material barrel for processing, and the material barrel is fixed in the inside of the sleeve frame 8, at this time the motor 4 drives the winding wheel 5 to wind the pull rope 11, so that the two sliding blocks 10 move upwards with the sleeve frame 8 through the rotating shaft 9, since the pull rope 11 always keeps in an inclined upward state to pull the sliding block 10, the sliding block 10 can be pulled to the horizontal part of the corner support 2;

[0044] It should be noted that the push block 30 is in the corner part of the corner support 2 under the elastic pressure of the second spring 34, that is, as long as the sliding block 10 just enters the horizontal part of the corner support 2, the blocking block 31 will be touched, and the second spring 34 is compressed through the push block 30, and at this time the sleeve frame 8 moves horizontally with the material barrel, during the horizontal movement, the rotating shaft 9 can be brought with the sleeve frame 8 and the internal material barrel through the meshing of the gear 32 and the rack 33, so as to realize the overturning of the sleeve frame 8 and the internal material barrel, thereby realizing the pouring of the chemical raw materials in the material barrel to the inlet of the processing equipment.

[0045] After the material is poured, the motor 4 slowly resets back with the winding wheel 5, at this time the pull rope 11 is slowly released, and the compressed second spring 34 pushes the sliding block 10 through the push block 30 and the blocking block 31, and the sliding block 10 brings the rotating shaft 9, the sleeve frame 8 and the material barrel back, when the sliding block 10 is elastically returned to the corner of the corner support 2, the sliding block 10, the rotating shaft 9, the sleeve frame 8 and the material barrel will automatically slide down under the action of gravity, thereby completing the reset after pouring the material.

[0046] Compared with the existing scheme of moving the plate chain with the material barrel horizontally to load, the loading mode of the present scheme is more stable and safer.

[0047] Embodiment two: please refer to Figures 3-5 The present embodiment is a further description of embodiment one, the top rod 12 is hollow, the end surface of the top rod 12 close to the center of the sleeve frame 8 is fixedly connected with the suction disc 13, and the end surface of the plurality of top rods 12 away from the suction disc 13 is fixedly connected with the soft tube 14, the upper end of the rotating disc 15 is fixedly provided with the sealing cylinder 19, and the sealing cylinder 19 is fixedly connected with the soft tube 14, the inside of the sealing cylinder 19 is slidably assembled with the piston disc 20, the top of the piston disc 20 is rotatably assembled with the threaded rod 21, and the threaded rod 21 is screwedly assembled with the sealing cylinder 19, the suction disc 13 can be abutted against the surface of the material barrel, and then the piston disc 20 is pulled to perform negative pressure treatment on the space between the suction disc 13 and the material barrel, so as to perform negative pressure suction positioning on the material barrel.

[0048] The interface of the tube 22 and the sealing cylinder 19 is below the piston disc 20, so that the piston disc 20 can be moved upward to suck the suction disc 13.

[0049] In this embodiment, considering that the material barrel can be made of plastic, the top rod 12 can cause the material barrel to deform when clamping the material barrel, or the chemical raw materials in the material barrel are too heavy, causing the material barrel to be separated from the top rod 12 during lifting;

[0050] In this scheme, when the top rod 12 clamps the material barrel, the suction disc 13 can be tightly attached to the outer wall of the material barrel, and then the piston disc 20 is moved upward by rotating the threaded rod 21, so that the air between the suction disc 13 and the material barrel is sucked, thereby achieving the effect of negative pressure adsorption. Through the negative pressure adsorption of the plurality of suction discs 13, the material barrel is clamped and sucked, which can further ensure the stability of the material barrel limited in the frame 8.

[0051] Embodiment three: please refer to Figure 8 and Figure 9 This embodiment is a further description of embodiment one. The auxiliary pouring unit includes an extension arc plate 35 fixedly arranged on the outer wall of the frame 8, and the extension arc plate 35 and the push rod 18 are oppositely distributed. The two side edges of the extension arc plate 35 and the frame 8 are fixedly provided with an edge plate 36, the bottom of the extension arc plate 35 is closed, the outer wall of the frame 8 is provided with a ring groove 37, and the ring groove 37 is located between the extension arc plate 35 and the two edge plates 36. The bottom of the ring groove 37 is provided with a plurality of through holes 38, and the through holes 38 and the storage box 39 are communicated. The extension arc plate 35 and the two edge plates 36 form a closed frame body, which covers the outer wall of the frame 8.

[0052] The extension arc plate 35 bends away from the center of the frame 8. When the frame 8 with the material barrel is inclined, the extension arc plate 35 can guide or converge the chemical raw materials spilled when the material barrel is inclined to the inside of the closed frame body.

[0053] In the embodiment, when the chemical raw material is liquid, the initial small-angle inclination of the bucket can make the liquid inside flow along the outer wall of the bucket mouth downward, and will not directly flow toward the inlet of the processing equipment. If the chemical liquid drips along the outer wall of the bucket downward, it is easy to cause injury to the equipment or the nearby workers. Therefore, in the present solution, the closed frame composed of the extension arc plate 35 and the edge plate 36 can collect the chemical raw material which flows along the bucket wall at the beginning, and can also converge to the inside of the storage tank 39 through the through hole 38, so as to avoid the chemical raw material from being splashed on the surface of the equipment or the nearby workers. When the inclination angle of the bucket is large, the liquid raw material inside the bucket can be directly poured into the inlet of the processing equipment. The liquid raw material temporarily converged in the storage tank 39 can also be poured out again and poured into the inlet of the processing equipment through the guidance of the extension arc plate 35, thereby improving the safety of pouring.
