Description

Technical Field

[0001] This utility model relates to the technical field of calcium carbonate granule packaging equipment, specifically a quantitative filling device for calcium carbonate packaging. Background Technology

[0002] Calcium carbonate is mainly used as a functional filler in the industrial field and is widely used in plastics, rubber, coatings and other fields. After the calcium carbonate is prepared, it needs to be packaged in packaging bags. Volumetric metering has the advantages of high accuracy, high efficiency and high stability over long period of operation. Therefore, this utility model proposes a quantitative filling device for calcium carbonate packaging. Summary of the Invention

[0003] The purpose of this invention is to provide a quantitative filling device for calcium carbonate packaging, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quantitative filling device for calcium carbonate packaging, comprising a storage silo and a discharge rack disposed below the storage silo. The storage silo is hollow inside, with an inlet pipe connected to the top and an inclined bottom with an outlet pipe connected to the lowest point. The bottom of the discharge rack has an annular groove, and a dispensing turntable is rotatably disposed within the groove. The top of the discharge rack has an opening, through which the outlet pipe communicates with the groove. The dispensing turntable is provided with multiple fixed compartments, and an extension compartment and a discharge compartment are detachably installed at the bottom of each fixed compartment. To facilitate the determination of when the material distribution turntable rotates, a microwave solid flow sensor can be installed inside the discharge pipe. This sensor uses 24GHz high-frequency microwaves and generates a measurement field through electromagnetic coupling. When solid particles flow, they reflect microwave signals, and the flow velocity and flow rate are calculated based on the Doppler effect. When no particle flow signal is detected inside the discharge pipe, it indicates that the metering space below, consisting of the fixed chamber, extended chamber, and discharge chamber, is full. At this point, the material distribution turntable can be rotated to allow the next metering space to rotate below the discharge pipe. Valves, such as powder butterfly valves or jaw discharge valves, are installed at the bottom of the discharge chamber, which can be selected according to actual needs.

[0005] Preferably, a rotating shaft is rotatably mounted on the discharge pipe. The bottom end of the rotating shaft is provided with spiral blades, and the top end extends out of the storage hopper and connects to the motor output end. The rotation of the rotating shaft and the blades on the rotating shaft, as well as the slight vibration generated during the operation of the motor, accelerates the material flow and prevents the material from getting stuck in the discharge pipe, thus affecting the material flow.

[0006] Preferably, a support ball is rotatably provided at the bottom of the outer ring of the material distribution turntable, and the support ball is slidably connected to an annular limiting groove formed on the inner wall of the chute. The support ball can reduce the friction force that the material distribution turntable needs to overcome when rotating, and avoid excessive energy loss during continuous operation.

[0007] Preferably, the bottom of the fixed compartment and the bottom of the extended compartment are provided with annular grooves, and the top of the extended compartment and the top of the discharge compartment are provided with annular protrusions. Threads that can be screwed together are provided in the annular grooves and on the annular protrusions. A motor for driving the material distribution turntable to rotate is provided inside the discharge rack.

[0008] Compared with the prior art, the beneficial effects of this utility model are: by driving the rotating shaft and the blades on the rotating shaft to rotate by the motor, and the slight vibration generated when the motor is running, the material flow is accelerated, preventing the material from getting stuck in the outlet pipe and affecting the material flow; the support ball can reduce the friction that needs to be overcome when the material distribution turntable rotates, and avoid excessive energy loss during continuous operation.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 A quantitative filling device for calcium carbonate packaging includes a storage silo 1 and a discharge rack 2 disposed below the storage silo 1. The storage silo 1 is hollow inside, with a feed pipe connected to the top and an inclined bottom with a discharge pipe 11 connected to the lowest point. The discharge rack 2 has an annular groove 21 at the bottom, and a distributing turntable 3 is rotatably disposed in the groove 21. The top of the discharge rack 2 has an opening, and the discharge pipe 11 communicates with the groove 21 through the opening. The distributing turntable 3 is provided with multiple fixed chambers 31, and an extension chamber 32 and a discharge chamber 33 are detachably installed at the bottom of the fixed chamber 31.

[0013] A rotating shaft is rotatably mounted on the discharge pipe 11. The bottom end of the rotating shaft has spiral blades, and the top end extends through the storage hopper 1 and connects to the motor output. A support ball is rotatably mounted on the bottom of the outer ring of the material distribution turntable 3. The support ball is slidably connected to an annular limiting groove formed on the inner wall of the slide groove 21. Annular grooves are formed at the bottom of the fixed hopper 31 and the bottom of the extended hopper 32. Annular protrusions are formed at the top of the extended hopper 32 and the top of the discharge hopper 33. Threads that can be screwed together are provided in the annular grooves and on the annular protrusions.

[0014] When using this device, based on the amount of material required for a single packaging, select an extension bin 32 of appropriate length and install it between the fixed bin 31 and the discharge bin 33. If they are connected by threads, it is necessary to check regularly whether the connection is loose. For long-term operation, other auxiliary fixing methods can be considered for fixing. When the equipment is running, the material in the storage bin 1 enters the metering space composed of the fixed bin, extension bin and discharge bin through the discharge pipe 11. After it is filled, the motor drives the material distribution turntable 3 to rotate, rotating the next metering space to be filled below the discharge pipe 11. The operator can hold the package open and place it below the filled metering space to receive the material falling after the discharge bin valve is opened.
