Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a raw material mixing device for refractory material production. Background Technology

[0002] With the increasing awareness of fire prevention in society, the application of refractory materials is becoming more and more widespread. In the process of processing these refractory materials, the raw material particles must first be mixed to improve the quality of the later production.

[0003] Currently, the methods for mixing raw material particles of refractory materials are generally quite simple, mainly through single-axis mixing. However, during the process, some lightweight raw material particles are prone to stratification due to their own density, resulting in uneven mixing. At the same time, dead corners appear at the bottom, causing some large particles to fail to break down in time during the mixing process, resulting in generally low overall mixing efficiency. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a raw material mixing device for refractory material production, which replaces the traditional raw material mixing method in the refractory material production process. This avoids the problem of stratification caused by different densities in the mixed raw materials and the problem of untimely crushing of large particles, which leads to low raw material mixing efficiency.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A raw material mixing device for refractory material production, comprising:

[0008] A mixing tank with a cover plate on top and a discharge pipe at the bottom;

[0009] A mixing mechanism is installed at the bottom of the cover plate. When the mixing mechanism is working, it continuously presses the upper layer of raw materials in the mixing tank downwards and simultaneously crushes the large particles of raw materials that are pressed to the bottom. At the same time, the crushed particles at the bottom are turned back to the upper layer from all sides.

[0010] In a preferred embodiment of the raw material mixing device for refractory material production described in this utility model, the top of the cover plate has a feed inlet.

[0011] As a preferred embodiment of the raw material mixing device for refractory material production described in this utility model, the mixing mechanism includes a mixing component installed at the bottom of the cover plate, a crushing component installed at the bottom of the mixing component, and a drive motor installed at the top of the cover plate with its output end connected to the mixing component.

[0012] As a preferred embodiment of the raw material mixing device for refractory material production described in this utility model, the mixing component includes a main shaft connected to the output end of the drive motor at its top, a spiral blade located on the side wall of the main shaft, and a plurality of inclined mixing plates installed on the side wall of the main shaft and evenly arranged along the circumferential direction.

[0013] The inner wall of the mixing tank is provided with an arc-shaped guide plate with the spiral blades rotating in opposite directions.

[0014] In a preferred embodiment of the raw material mixing device for refractory material production described in this utility model, the crushing component includes a connecting seat located at the bottom of the main shaft and a plurality of triangular crushing teeth located on the circumferential sidewall of the connecting seat.

[0015] As a preferred embodiment of the raw material mixing device for refractory material production described in this utility model, it further includes a dust collection mechanism, which includes a dust collection box installed on the side wall of the mixing tank, a dust collection pipe with one end connected to the input end of the dust collection box and the other end respectively corresponding to the feed inlet and the discharge pipe, and a dust discharge pipe with one end connected to the output end of the dust collection box and the other end connected to the dust filtration mechanism.

[0016] Compared with the prior art, the beneficial effects of this utility model are that the raw material mixing device for refractory material production, through the operation of the mixing mechanism, continuously presses the upper layer of lightweight homogeneous material inside the mixing tank downwards, thereby avoiding the stratification of raw materials. The large raw materials pressed to the bottom are crushed, and at the same time, the crushed raw materials are turned back to the upper layer from all sides, thus making the mixing between the layers of raw materials more thorough. This replaces the traditional raw material mixing method in the refractory material production process, avoiding the problem of stratification caused by different densities in the mixed raw materials and the problem of low raw material mixing efficiency due to untimely crushing of large homogeneous materials.

[0025] This utility model provides a raw material mixing device for refractory material production, which replaces the traditional raw material mixing method in the refractory material production process. It avoids the problem of low raw material mixing efficiency caused by stratification due to different densities in the mixed raw materials and the untimely crushing of large particles.

[0026] Figures 1-3 The diagram shown is a structural schematic of a raw material mixing device for refractory material production according to this utility model. Please refer to [link / reference]. Figures 1-3 This paper provides a detailed introduction to the raw material mixing device used in the production of this type of refractory material.

[0027] Example 1

[0028] refer to Figures 1-3This utility model discloses a raw material mixing device for refractory material production, the main part of which includes a mixing tank 100 and a mixing mechanism 200.

[0029] The mixing tank 100 is used to carry the raw materials of the refractory material to be mixed. The mixing tank 100 has a cover plate 120 on the top and a discharge pipe 110 at the bottom. The cover plate 120 is used to seal the top of the mixing tank 100. The discharge pipe 110 is used to facilitate the discharge of the raw materials after they are fully mixed. The side wall of the discharge pipe 110 has a control valve to control the discharge time and flow rate of the discharge pipe 110.

[0030] The mixing mechanism 200 is used to fully mix the raw materials in the mixing tank 100. The mixing mechanism 200 is installed at the bottom of the cover plate 120. When the mixing mechanism 200 is working, it continuously presses the upper layer of raw materials in the mixing tank 100 downwards and simultaneously crushes the large particles of raw materials that are pressed to the bottom. At the same time, the crushed particles at the bottom are turned back to the upper layer from all sides. Thus, when the mixing mechanism 200 is working, it continuously presses the light raw materials in the upper layer of the mixing tank 100 downwards, preventing the raw materials from separating. The large particles of raw materials that are pressed to the bottom are simultaneously crushed and turned back out from all sides, thereby making the raw materials more fully mixed.

[0031] In this embodiment, the specific usage process is as follows: After various raw material particles enter the mixing tank 100, they are mixed by the mixing mechanism 200. During this process, the upper light raw material is continuously pressed down to the bottom to avoid material stratification. The large raw material particles pressed down to the bottom are simultaneously broken and flipped back to the upper layer from all sides, so that the raw materials in each layer are mixed more thoroughly.

[0032] Example 2

[0033] Based on Example 1, the top of the cover plate 120 has a feed inlet 120a for conveniently adding raw material particles into the mixing tank 100.

[0034] In this embodiment, the mixing mechanism 200 includes a mixing component 210 installed at the bottom of the cover plate 120, a crushing component 220 installed at the bottom of the mixing component 210, and a drive motor 230 installed at the top of the cover plate 120 and connected to the mixing component 210 at its output end. The mixing component 210 is used to mix the raw materials in the mixing tank 100 during operation. The crushing component 220 is used to crush the large particles of raw materials that have been pressed down to the bottom for secondary processing. The drive motor 230 is used to drive the mixing component 210 to work during operation.

[0035] In this embodiment, the mixing component 210 includes a main shaft 210a connected to the output end of the drive motor 230 at its top, a spiral blade 210b located on the side wall of the main shaft 210a, and a plurality of inclined mixing plates 210c installed on the side wall of the main shaft 210a and evenly arranged along the circumferential direction. When the drive motor 230 drives the main shaft 210a to rotate, it drives the spiral blade 210b, the inclined mixing plates 210c, and the crushing component 220 to rotate. When the spiral blade 210b rotates, it mixes the raw materials while continuously pressing the upper layer of raw materials downward. When the inclined mixing plates 210c rotate, they stir and mix the raw materials while continuously turning the raw materials upward, thereby making the various raw materials more thoroughly mixed.

[0036] The inner wall of the mixing tank 100 is provided with an arc-shaped guide plate 130 with opposite spiral blades 210b, which is used to extend the residence time of the material in each layer of the tank, thereby facilitating the more complete crushing of large particles.

[0037] In this embodiment, the crushing assembly 220 includes a connecting seat 220a located at the bottom of the main shaft 210a and a plurality of triangular crushing teeth 220b located on the circumferential sidewall of the connecting seat 220a. The connecting seat 220a is used to facilitate the installation of the triangular crushing teeth 220b, and the triangular crushing teeth 220b are used to crush large particles of raw materials when rotating at high speed.

[0038] In this embodiment, the specific workflow is as follows: When the drive motor 230 is working, it drives the main shaft 210a to rotate. When the main shaft 210a rotates, it drives the spiral blades 210b to rotate at high speed. When the spiral blades 210b rotate, they mix the raw materials and continuously press the upper layer of light materials downward, thereby preventing the raw materials from separating. The large particles of raw materials that are pressed to the bottom are crushed by the crushing component 220. At the same time, when the inclined mixing plate 210c rotates, it continuously flips the crushed raw materials from all sides upward, thereby making the materials of each layer more fully mixed.

[0039] Example 3

[0040] Based on Embodiment 2, a dust collection mechanism 300 is also included to prevent dust overflowing during raw material mixing and discharge from polluting the air. The dust collection mechanism 300 includes a dust collection box 310 installed on the side wall of the mixing tank 100, a dust collection pipe 320 with one end connected to the input end of the dust collection box 310 and the other end connected to the feed inlet 120a and the discharge pipe 110 respectively, and a dust discharge pipe 330 with one end connected to the output end of the dust collection box 310 and the other end connected to the dust filtration mechanism. The dust collection box 310 is used to draw in external air through the input end and discharge it from the output end when it is working. The dust collection pipe 320 is used to guide the dust overflowing through the feed inlet 120a and the discharge pipe 110 into the dust collection box 310 when the dust collection box 310 is working. The dust discharge pipe 330 is used to guide the dust discharged from the dust collection box 310 into the dust and impurity treatment structure for filtration treatment, thereby preventing the dust generated during raw material mixing and discharge from polluting the surrounding air.
