Description

Technical Field

[0001] The utility model relates to the field of refractory material packaging equipment, and particularly relates to an automatic dispensing device for refractory plastic mass. Background Art

[0002] Refractory plastic mass is a material composed of small irregular block structures, which is widely used in high-temperature industrial environments such as steel, glass, ceramics and other fields. Due to its excellent high-temperature resistance and plasticity, refractory plastic mass is widely used in the manufacture of lining materials. However, during transportation and transfer, these small irregular block structures often form powdery materials due to mutual friction and collision. These powdery materials may cause a series of problems during subsequent dispensing and use.

[0003] In the existing refractory plastic mass dispensing devices, the block materials and powdery materials are usually mixed and dispensed together. However, the powdery materials are easily dispersed in the air during the dispensing process, which not only causes material waste, but also pollutes the production environment, increasing the health risks of operators and potential safety hazards in production. Therefore, how to effectively separate and process the powdery materials during the dispensing process is a difficult problem in the prior art. Based on this, we propose an automatic dispensing device for refractory plastic mass. Content of the Utility Model

[0004] In order to solve the technical problems existing in the above-mentioned prior art, the utility model provides an automatic dispensing device for refractory plastic mass.

[0005] To achieve the above object, the utility model provides the following technical solution: an automatic dispensing device for refractory plastic mass, which includes a feed bin erected on a frame. An outlet bin is installed at the lower outlet of the feed bin. A grading disc is rotatably installed inside the outlet bin. A number of leakage holes are provided on the grading disc, and the diameter of the leakage holes gradually increases along the radial direction of the grading disc outward. A thick material pipe is connected and installed around the lower end of the outlet bin, and a thin material pipe is connected and installed at the center of the lower end of the outlet bin. A movable pipe is installed at the lower end of the thin material pipe and is slidably assembled in the vertical direction.

[0006] Preferably, a spiral shaft is fixedly installed at the center of the upper end of the grading disc. The upper end of the spiral shaft is fixedly connected to the motor shaft of a motor. The motor is fixedly installed on the feed bin through a fixing plate.

[0007] Preferably, an auger is fixedly sleeved on the circumferential surface of the spiral shaft.

[0008] Preferably, the grading disc has a basin-like structure, and a relatively closed space is formed between the grading disc and the top wall of the inner cavity of the feed bin.

[0009] Preferably, a conical hopper is installed at the discharge port of the fine material pipe. A fixed pipe arranged vertically is installed at the lower end of the conical hopper. The movable pipe is slidably sleeved on the circumferential surface of the fixed pipe. An electric cylinder is fixedly installed on the circumferential surface of the conical hopper, and the piston rod of the electric cylinder is fixedly connected to the movable pipe.

[0010] Preferably, a bearing is fixedly sleeved on the outer circumferential surface of the grading disc, and the outer ring of the bearing is fixedly installed in the discharge bin.

[0011] Preferably, conveying devices for conveying the packaging containers are arranged directly below both the coarse material pipe and the fine material pipe.

[0012] Compared with the prior art, the utility model provides a refractory plastic automatic packaging device, which has the following beneficial effects:

[0013] (1) By arranging the grading disc, the refractory plastic is graded by the centrifugal force. Among them, the bulk-structured materials with larger particle sizes are discharged through the coarse material pipe in a way of pouring from above the powder container, and the powdery-structured materials with smaller particle sizes are discharged through the fine material pipe in a way of slowly discharging from the bottom of the container upwards. Different discharging methods are adopted according to the particle size of the materials, which not only ensures the smooth progress of the packaging process, but also effectively reduces the dust pollution.

[0014] (2) The powdery-structured refractory plastic is discharged in a segmented manner, which greatly reduces the diffusion risk of the powdery materials during the packaging process, improves the working environment, protects the health of the operators, reduces the waste of materials, and at the same time reduces the safety hazards such as explosion and fire, and improves the overall production safety of the factory.

[0015] (3) By designing the auger, the refractory plastic in the silo is segmented and conveyed to the grading disc, avoiding excessive materials entering the grading disc in a short time and improving the quality of material grading.

[0016] (4) The refractory plastic is graded by the grading disc according to the particle size, which is convenient for separating and using the refractory plastic with different particle sizes subsequently, and selecting the appropriate particle size according to the actual application requirements, so as to optimize the overall performance of the material.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the present invention to be protected, but only represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0025] This embodiment proposes a refractory plastic automatic packaging device, as Figures 1 to 5As shown in the figure, it includes a silo 1 installed on a frame 11. A discharge silo 2 is installed at the lower discharge port of the silo 1, and a discharge pipe 6 is installed at the lower discharge port of the discharge silo 2. A conveying device for conveying packaging containers is arranged directly below the discharge pipe 6. During packaging, the conveying device transports the packaging container to directly below the discharge pipe 6. The refractory plastic stored in the silo 1 is poured into the packaging container through the discharge pipe 6. During this process, since the refractory plastic is in a fine and irregular block structure, some of the refractory plastic forms a powdery structure due to mutual extrusion during transportation and transfer. During the discharging process, dust is extremely likely to pervade the environment, which not only causes material waste, but also pollutes the production environment, increasing the health risks of operators and potential production safety hazards. Therefore, we separate the refractory plastic in block structure and powdery structure. Among them, the refractory plastic in block structure is discharged in a normal way to ensure the packaging efficiency, and the refractory plastic in powdery structure is discharged in a segmented way. The powdery material is slowly discharged by a way of gradually rising from the bottom of the container, avoiding the sudden release and diffusion of the powdery material. Specifically, a grading disk 3 is rotatably installed inside the discharge silo 2. A number of leakage holes are provided on the grading disk 3, and the diameter of the leakage holes gradually increases along the radial direction of the grading disk 3 outward. A thick material pipe 4 is connected and installed around the lower end of the discharge silo 2, and a thin material pipe 5 is connected and installed at the center of the lower end of the discharge silo 2. A movable pipe 63 is installed at the lower end of the thin material pipe 5 and is slidably assembled in the vertical direction. The refractory plastic is initially separated by the rotating grading disk 3. The centrifugal force throws the heavier block materials towards the silo wall, while the lighter powdery materials are concentrated in the central area of the discharge silo 2. The block materials fall into the thick material pipe 4 through the large leakage holes provided on the outer side. During discharging, the block materials are poured into the container from above the packaging container, while the powdery materials fall into the thin material pipe 5 through the small leakage holes provided in the central area. The movable pipe 63 extends vertically to the inner bottom of the packaging container and gradually moves upward as the discharging operation of the powdery material proceeds, realizing the segmented discharging of the powdery material.

[0026] Specifically, a spiral shaft 31 is fixedly installed at the center of the upper end of the grading disk 3. The upper end of the spiral shaft 31 is fixedly connected to the motor shaft of a motor 33. The motor 33 is fixedly installed on the silo 1 through a fixing plate 34. After starting the motor 33, the motor shaft of the motor 33 drives the grading disk 3 to rotate at a high speed. In this embodiment, in order to improve the rotational stability of the grading disk 3, a bearing is fixedly sleeved on the outer circumferential surface of the grading disk 3, and the outer ring of the bearing is fixedly installed inside the discharge silo 2.

[0027] When the above solution is implemented, if the amount of refractory plastic in the silo 1 entering the grading disk 3 at one time is too large, it will affect the subsequent material separation quality. Therefore, a screw 32 is fixedly sleeved on the circumferential surface of the screw shaft 31, and the material in the silo 1 is conveyed into the grading disk 3 in sections through the screw 32. During the conveying process, the agglomerated refractory plastic can also be separated and dispersed.

[0028] In order to ensure that the weather-resistant plastic entering the grading disk 3 is all affected by the centrifugal force, the grading disk 3 is designed as a basin-like structure, and a relatively closed space is formed between the grading disk 3 and the top wall of the inner cavity of the silo 1.

[0029] In addition, in this embodiment, the sliding of the movable pipe 63 in the vertical direction is driven by the electric cylinder 64. Specifically, a conical hopper 61 is installed at the discharge port of the fine material pipe 5, and a fixed pipe 62 arranged in the vertical direction is installed at the lower end of the conical hopper 61. The movable pipe 63 is slidably sleeved on the circumferential surface of the fixed pipe 62. An electric cylinder 64 is fixedly installed on the circumferential surface of the conical hopper 61, and the piston rod of the electric cylinder 64 is fixedly connected to the movable pipe 63. After the packaging container moves to directly below the movable pipe 63, the electric cylinder 64 is started. The piston rod of the electric cylinder 64 extends and drives the movable pipe 63 to penetrate to the bottom of the packaging container. As the discharging operation proceeds, the movable pipe 63 gradually moves upward until it resets to ensure that the powdery material is slowly discharged in a way that gradually moves upward from the bottom of the container.

[0030] In this embodiment, the conveying device includes a coarse material conveyor belt 7 arranged directly below the coarse material pipe 4 and a fine material conveyor belt 8 arranged directly below the movable pipe 63. Different particle size refractory plastics are conveyed by the two conveyor belts. Among them, different particle size refractory plastics can be separated and used, and the appropriate particle size can be selected according to the actual application requirements, so as to optimize the overall performance of the material. For example, small particles have good fluidity and sealing performance, can fill the voids in the material, and enhance the denseness of the refractory lining; while larger particles help to enhance the strength and thermal shock resistance of the material.
