Description

Technical Field

[0001] The utility model relates to the technical field of chemical raw material transportation, in particular to a chemical raw material spiral conveying device. Background Art

[0002] There are many kinds of chemical raw materials, and their uses are very wide. There are 5 to 7 million kinds of chemicals in the world, and more than 100,000 kinds of chemicals are sold and circulated in the market. In addition, more than 1,000 new chemicals are introduced every year, and 150 to 200 of them are considered carcinogens. Although many chemical raw materials are very harmful to the human body, they are also necessary for human survival.

[0003] Chinese patent announcement number CN 211619067 U discloses a screw feeding device for conveying chemical raw materials, including a U-shaped bin and a sealing cover hinged on the upper end of the U-shaped bin, a shaft rod is rotatably connected inside the U-shaped bin, a spiral blade is fixedly connected to the shaft rod, a cleaning mechanism is arranged on the sealing cover, and the cleaning mechanism includes a threaded rod, a rotating plate and a brush from top to bottom, a rotating disk is fixedly connected to one end of the threaded rod, and the other end of the threaded rod passes through the sealing cover and is movably connected to the mounting plate, cavities are arranged at both ends of the side wall of the U-shaped bin, a nozzle is installed in the cavity, and the nozzle is connected to a water source through a water pump, and a shielding mechanism is arranged at one end of the cavity close to the spiral blade;

[0004] The above-mentioned spiral feeding device transports chemical raw materials by utilizing the continuous rotation of spiral blades. When transporting chemical raw materials, the spiral blades carry away the chemical raw materials in the hopper at the bottom of the feeding device. However, chemical raw materials are mostly corrosive, carcinogenic and other properties that cause serious harm to the human body. When the staff puts the chemical raw materials into the hopper, they are bound to touch the packaging bags of the chemical raw materials. In this process, the chemical raw materials will adhere to the skin of the staff, thereby causing harm to the staff. In addition, when pouring the powdered chemical raw materials into the hopper, the dust generated by the scattered chemical raw materials will enter the body of the staff through the staff's breathing and cause harm to the staff's body.

The whole process does not require close operation by staff, so as to solve the technical problems raised by the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A chemical raw material screw conveying device comprises a hopper, the bottom of which is fixedly connected to a feed bin by bolts, the bottom of which is fixedly connected to a feed port of an outer cylinder by bolts, and a screw is arranged inside the outer cylinder;

[0008] The top of the hopper is rotatably connected to a rotating plate, and a plurality of hooks are uniformly welded on the top of the rotating plate at one end away from the hopper; connecting shafts are welded on both sides of the end of the rotating plate away from the hooks, and hydraulic cylinders are arranged under the two connecting shafts, and the two connecting shafts are rotatably connected to the telescopic rods of the two hydraulic cylinders respectively;

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model first uses a forklift or other transport tool to move the bag containing chemical raw materials and place it on a rotating plate in a horizontal state. Then two hydraulic cylinders synchronously drive the rotating plate to rotate in the opposite direction. The rotating plate rotates in a circle with the connection with the hopper, and the rotating plate lifts the bag during rotation, so that the bag gradually becomes vertical. As the rotating plate gradually tilts, the bag on the rotating plate slides downward under the action of gravity.

The blade cuts the bag while rising, so that the chemical raw materials in the bag fall into the hopper; the rectangular through grooves arranged on the rotating plate can not only enable the blade to move normally, but also allow the blade to pass through the rotating plate to contact the bag and cut the bag; in the process of the rotating plate rotating to lift the bag and the blade cutting the bag, the staff does not need to operate at close range, which can effectively prevent the staff from contacting the chemical raw materials, thereby ensuring the safety of the staff;

[0018] 3. In the utility model, a material-shifting plate is provided on the inner side of the feed bin. Under the control of a motor, the material-shifting plate can rotate at a uniform speed. When rotating, the material-shifting plate can shift the chemical raw materials in the feed bin to break up the chemical raw materials in the feed bin, increase the fluidity of the chemical raw materials, and effectively prevent the chemical raw materials from accumulating at the bottom of the feed bin and the hopper, so that the chemical raw materials can smoothly enter the outer cylinder; the sealing plates on the top of the multiple outer cylinders cover the multiple outer cylinders, and when the screw transports the chemical raw materials, the sealing plates can prevent the chemical raw materials in the outer cylinder from overflowing, so that the environment around the conveying equipment will not be polluted by the chemical raw materials.
