[0002] Mineral powder is a general term for stone powder and its substitutes that meet engineering requirements. It is the product after crushing and processing of ore, and is the first and one of the most important steps in ore processing and smelting. Adding mineral powder to building materials can effectively improve the compressive strength of concrete, reduce the production cost of building materials, and at the same time has obvious effects on inhibiting alkali-aggregate reaction, reducing hydration heat, reducing early temperature cracks in concrete structures, improving the density of concrete, and improving impermeability and erosion resistance.

[0003] The existing Chinese patent with the publication number of CN 216154774 U discloses a mineral powder conveyor, including a machine body. A support plate is provided at the left end of the machine body, and a plurality of support feet are provided at the lower end of the support plate. A conduit is installed on the left end wall of the machine body. A water pipe is provided at the right end of the conduit, and a plurality of nozzles are provided on the water pipe. A conveying pipe is installed at the right end of the machine body. A splicing flange is provided at the right end of the conveying pipe. A screw is installed inside the conveying pipe. A water pump is provided at the lower end of the conduit. The conduit penetrates the left end wall of the machine body and is communicated with the water pipe. When the machine body is used up, the water pump is started to introduce external water source, which is sprayed out by the nozzles, so as to facilitate the cleaning of the inside of the machine body and the conveying pipe, avoid mineral powder sticking to the inner wall of the machine body, is beneficial to the maintenance of the machine body, and effectively improves its functionality; and the conveying pipe can be lengthened through the splicing flange, so as to facilitate the lengthening of the mineral powder conveying distance, without moving the equipment, which is convenient and fast, and effectively improves its functionality and practicability.

[0004] However, the above-mentioned conveying device has the following disadvantages: Before the mineral powder is conveyed, when the mineral powder is poured into the hopper, due to the mismatch between the diameter of the discharge pipe of the storage bin and the diameter of the feed pipe of the conveying pipe, the mineral powder is likely to fly and scatter, pollute the transportation environment, and cause waste of mineral powder.

[0005] Therefore, it is necessary to provide a mineral powder conveying device to solve the above technical problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a mineral powder conveying device, which has the effects of reducing environmental pollution and reducing waste of mineral powder.

[0007] The above technical object of the present utility model is achieved through the following technical solutions: A mineral powder conveying device includes a support base and a conveying pipe. The support base and the conveying pipe are fixedly connected. One end of the conveying pipe is fixedly connected with a feed inlet. A conveying mechanism is arranged inside the conveying pipe. A plurality of fixing rings are slidably connected inside the feed inlet. The diameters of the plurality of fixing rings decrease arithmetically from outside to inside.

Press down the fixing ring through the discharge pipe. The fixing ring compresses the spring through the slider, so that the connection part between the discharge pipe and the fixing ring moves down into the feed inlet and is in a sealed state. Then feed the material into the feed inlet. After the required mineral powder is conveyed, let it stand for a period of time, and then move the discharge pipe away. After the discharge pipe is moved away, the fixing ring moves up to its original position under the action of the spring force. The fixing ring prevents mineral powder from scattering when the discharge pipe discharges, reducing environmental pollution and reducing mineral powder waste.

[0009] The further setting of the present utility model is: The conveying mechanism includes a motor and a spiral blade. A motor is fixedly installed on the outside of one end of the conveying pipe. The output end of the motor penetrates the side wall of the conveying pipe and is fixedly connected with a feeding rod. The feeding rod is rotatably installed inside the conveying pipe. A spiral blade is fixedly installed on the feeding rod.

[0010] By adopting the above technical solutions, when conveying mineral powder, start the motor. The output end of the motor drives the feeding rod and the spiral blade to rotate to convey the mineral powder.

[0011] The further setting of the present utility model is: The other end of the conveying pipe is provided with a splicing flange.

[0012] By adopting the above technical solutions, the conveying pipe can be lengthened through the splicing flange.

[0013] The further setting of the present utility model is: A plurality of placement grooves are arranged on the inner wall of the conveying pipe. A ring-shaped heating block is fixedly installed in the plurality of placement grooves. An electric heating wire (not shown in the figure) is arranged inside the ring-shaped heating block.

[0014] By adopting the above technical solutions, when the mineral powder is damp and caked, the electric heating wire makes the ring-shaped heating block heat the conveying pipe, thereby drying and dehumidifying the mineral powder.

[0015] A further setting of the present utility model is that an air outlet pipe is fixedly connected to one end of the conveying pipe far away from the motor.

[0016] By adopting the above technical solution, the water vapor generated during the drying and dehumidification process of the ore powder can be discharged from the air outlet pipe.

[0017] A further setting of the present utility model is that a filter screen is fixedly installed at one end of the conveying pipe far away from the feed inlet.

[0018] By adopting the above technical solution, when the ore powder reaches the filter screen under the action of the spiral blade, the agglomerated ore powder can be extruded through the filter screen, thereby removing the lumpy ore powder.

[0019] To sum up, the present utility model has the following beneficial effects: When it is necessary to convey ore powder, first place the discharge pipe of the ore powder storage bin above the feed inlet, then lower the discharge pipe to the fixing ring with the same pipe diameter, press down the fixing ring through the discharge pipe, the fixing ring compresses the spring through the slider, so that the connection between the discharge pipe and the fixing ring moves down into the feed inlet and is in a sealed state. Then feed the material into the feed inlet, and start the motor while feeding. The output end of the motor drives the feeding rod and the spiral blade to rotate to convey the ore powder. After completing the conveyance of the required ore powder, let it stand for a period of time, and then remove the discharge pipe. After the discharge pipe is removed, the fixing ring moves up to its original position under the action of the spring force. The fixing ring prevents the ore powder from flying when discharging the material, reducing environmental pollution and ore powder waste. BRIEF DESCRIPTION OF THE DRAWINGS
