Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, and in particular relates to a mixing tank feeding device. Background Art

[0002] When adding materials to the sodium hydroxide preparation tank in the workshop, the bagged solid sodium hydroxide is hoisted to the working platform on the top of the tank, and the operator manually pours the material into the feeding hole of the tank. In daily operations, sodium hydroxide is a strong alkaline material, and the melt is splashed during the preparation process. If human skin comes into contact with sodium hydroxide powder or splashing droplets, it will cause burns to the human body. Therefore, a feeding device is used to feed the preparation tank. However, when the existing feeding device is in use, the feed hopper is fixed and cannot be adjusted, which makes it inconvenient to discharge the material. At the same time, dust is generated during the discharge, which causes the dust to enter the air and cause pollution. Summary of the invention

[0003] The utility model aims to provide a mixing trough feeding device, which solves the problem that the feed hopper of the existing mixing trough feeding device is fixed and cannot be adjusted, thereby making it inconvenient to discharge materials, and dust is generated during discharge, which causes dust to enter the air and cause pollution.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a mixing trough feeding device, including a feed hood, a feed hopper is slidably connected to the inside of the feed hood, an adjustment mechanism is provided on the feed hopper, a collecting barrel is detachably mounted on the upper end of the feed hood, a suction pump is fixedly mounted on the upper end of the collecting barrel, the suction pump passes through the collecting barrel and is fixedly connected to the collecting barrel, a filter is fixedly connected to the inside of the collecting barrel, and a dust collection mechanism is provided inside the collecting barrel.

[0005] The principle of the utility model is that when in use, the material is poured into the feed hopper, and then the screw and the screw barrel are rotated to make a threaded motion, so that the screw barrel moves toward the support plate, the screw barrel drives the suspension rod to deflect, the suspension rod drives the hanger to deflect, so that the angle of the feed hopper changes, so that the material is easy to slide down, by rotating the screw and the screw barrel to make a threaded motion, so that the screw barrel drives the suspension rod to deflect, so that the angle of the feed hopper changes, so that after the material is put into the feed hopper, the angle of the feed hopper changes, so that the material is easy to enter the feed cover, and at the same time, the suction pump is started, and the suction pump sucks to form a negative pressure in the collecting barrel. The pressure causes the sealing head to be sucked by the negative pressure and separated from the conical cylinder, so that the conical cylinder and the feed cover are connected, so that the dust raised in the feed cover is sucked into the collecting cylinder. In this process, the sealing head drives the guide rod to move upward, and the guide rod drives the baffle to move upward. The moving up of the baffle compresses the spring. When the suction pump stops working, the spring resets the sealing head so that it is pressed tightly on the conical cylinder, sucked by the suction pump and filtered through the filter, so that the dust can easily enter the interior of the collecting cylinder, and the spring action makes the sealing head automatically reset to seal the upper end of the conical cylinder, so that the dust is not easy to overflow from the collecting cylinder after being collected.

[0006] The beneficial effect of the utility model is that the screw and the barrel are rotated to make a threaded motion, so that the barrel drives the suspension rod to deflect, so that the angle of the feed hopper changes, so that after the material is put into the feed hopper, the angle of the feed hopper changes, so that the material can enter the feed cover easily;

[0007] The dust is sucked by the suction pump and filtered through the filter, so that it is easy for the dust to enter the interior of the collection tube, and the sealing head can automatically reset to seal the upper end of the conical tube through the action of the spring, so that the dust is not easy to escape from the collection tube after being collected.

[0008] Furthermore, a support block is welded inside the feed cover, and the support block is hinged to the feed hopper. By arranging the support block, the feed hopper is auxiliary supported.

[0009] Furthermore, the adjustment mechanism includes a hanger, a suspension rod, a support plate, a screw, a screw barrel, and a knob. A hanger is welded to the upper end of the feed hopper, a suspension rod is hinged to the middle of the upper end of the hanger, a support plate is welded to the left edge of the upper end of the feed cover, a screw is installed inside the support plate through a bearing, and a screw barrel is connected to the outer side of the screw through a thread. By rotating the screw and the screw barrel to make a threaded motion, the screw barrel drives the suspension rod to deflect, and the angle of the feed hopper changes, so that after the material is placed in the feed hopper, the angle of the feed hopper changes, making it easier for the material to enter the feed cover.

[0010] Furthermore, a knob is fixedly connected to the right end of the screw rod, and the knob is in contact with the support plate. By providing the knob, the screw rod is easy to rotate.

[0011] Furthermore, the dust collecting mechanism includes a conical tube, a connecting rod, a support ring, a guide rod, a sealing head, a baffle, and a spring. The inner bottom of the collecting tube is fixedly connected with the conical tube, the inner wall of the conical tube is welded with a connecting rod, the end of the connecting rod is welded with a support ring, the inside of the support ring is slidably connected with a guide rod, the upper end of the guide rod is fixedly connected with a sealing head, the lower end of the guide rod is welded with a baffle, and a spring is arranged on the outside of the guide rod. The dust is sucked by a suction pump and filtered by a filter, so that the dust can easily enter the interior of the collecting tube, and the sealing head can automatically reset to block the upper end of the conical tube through the action of the spring, so that the dust is not easy to overflow from the collecting tube after being collected.

[0012] Furthermore, the sealing head is made of rubber material, and the sealing head is in contact with the conical tube. By setting the sealing head, the upper end of the conical tube is blocked.

[0013] Furthermore, one end of the spring is fixedly connected to the baffle, and the other end of the spring is fixedly connected to the support ring. By providing the spring, the baffle is easy to reset. BRIEF DESCRIPTION OF THE DRAWINGS

The screw 44 and the screw barrel 45 are rotated to make a threaded movement. The right end of the screw 44 is fixedly connected with a knob 46, and the knob 46 is in contact with the support plate 43. By setting the knob 46, the screw 44 is easy to rotate, and then the screw barrel 45 drives the hanger rod 42 to deflect, so that the angle of the feed hopper 3 changes, and then the material can be put into the feed hopper 3. The angle of the feed hopper 3 changes, so that the material can enter the feed cover 1 easily.

[0022] like Figure 3 , Figure 4 As shown, the dust collecting mechanism 8 includes a conical cylinder 81, a connecting rod 82, a support ring 83, a guide rod 84, a sealing head 85, a baffle 86, and a spring 87.

When the suction pump 6 stops working, the spring 87 resets the sealing head 85 so that it is pressed tightly on the conical cylinder 81, sucked by the suction pump 6 and filtered by the filter screen 7, so that the dust can easily enter the interior of the collection cylinder 5. In addition, the spring 87 can automatically reset the sealing head 85 to block the upper end of the conical cylinder 81, so that the dust is not easy to overflow from the collection cylinder 5 after being collected.
