Description

Technical Field

[0001] The utility model relates to the technical field of concrete preparation, in particular to a mixing device for making anti-caking refractory mud. Background Art

[0002] Refractory mud, also known as fire mud or joint mud. It is used as a caulking material for refractory masonry. According to the material, it can be divided into clay, high-alumina, siliceous and magnesia refractory mud. It is composed of refractory powder, binder and admixture. Almost all refractory raw materials can be made into powder for preparing refractory mud. Ordinary refractory mud is made of refractory clinker powder and a proper amount of plastic clay as a binder and plasticizer. Its strength at room temperature is relatively low, and it has higher strength when it forms a ceramic bond at high temperature.

[0003] The preparation method of refractory mud is as follows: in the preparation of clay refractory mud, the Al2O3 content is >40%, high-alumina cement and clay refractory clay are evenly mixed, the mass ratio (cement: refractory clay) is 1:2 or 1:3, and water is added to stir, and the mixture is stirred evenly into a thick paste without lumps. If the stirring intensity is low and the cement agglomerates, its strength will be significantly reduced, and the agglomerated cement is mixed with other materials for tiling tiles, and the tiles are prone to cracking or even falling off in the later stage, which will seriously affect production.

[0004] Based on this, the present application proposes a mixing device for making anti-caking refractory clay. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a mixing device for making anti-caking refractory mud.

[0006] The technical solution of the utility model is: a mixing device for making anti-caking refractory mud, comprising a mixing box, and a crushing component, a heating component and a mixing component arranged in the mixing box from top to bottom;

[0007] The crushing assembly comprises two crushing rollers rotatably arranged in the mixing box and meshing with each other, and two driving members respectively fixedly arranged on one end of the rotating shaft corresponding to the crushing rollers; the two rotating shafts are respectively connected to the output end of the motor used to drive the crushing rollers to rotate;

[0008] The heating assembly comprises a threaded tube rotatably arranged in the mixing box and located below the middle of the two crushing rollers, a plurality of heating rods threadedly connected to the threaded tube, a mounting plate fixedly sleeved on one end of the threaded tube, and a plurality of convex columns circumferentially spaced on the mounting plate; the driving member contacts the convex columns;

[0009] Description: The crushing roller can be set to pre-crush the material, so that the large pieces of material can be broken into smaller ones, reducing the agglomeration phenomenon in the refractory mud production process at the source. The driving column uses the forward and reverse reciprocating drive of the threaded tube to achieve efficient adjustment of the heating position of the heating rod inside the mixing device, further improving the heating efficiency, thereby reducing the agglomeration of the refractory mud.

[0010] Furthermore, the mixing box includes a heating chamber for placing the heating assembly, and a crushing chamber arranged on the heating chamber and having an arc-shaped bottom; a feed port is arranged at the top of the crushing chamber, a discharge port is arranged at the bottom of the heating chamber, and a solenoid valve for controlling the opening and closing of the discharge port is arranged at the discharge port;

[0011] Description: The arc-shaped structure at the bottom of the crushing chamber can better match the structure of the crushing roller, effectively reducing the situation where the material enters the heating chamber directly from both sides without being crushed, thereby reducing the frequency of agglomeration in the device.

[0012] Further, the mixing assembly includes a mounting plate arranged on the side wall of the mixing box, a central shaft rotatably arranged at the center of the mounting plate and connected to the threaded tube through a transmission belt, two spring rods symmetrically arranged and connected to the mounting plate at one end, two adjustment plates respectively slidably arranged in the slide grooves on the side wall of the mixing box through sliders and connected to the other ends of the spring rods, and a paddle plate group arranged on the central shaft and capable of contacting the adjustment plates;

[0013] Description: The above arrangement can utilize the transmission belt to drive the central axis to realize the reciprocating rotation of the central axis, and utilize the paddle group to alternately push the adjustment plates on both sides. After each push, the adjustment plates can be reset under the action of the spring rod, thereby realizing the mixing of the materials. Moreover, with the high-frequency disturbance of the materials by the adjustment plates, the contact between the materials and the heating rods can be further increased, thereby reducing the agglomeration of the materials.

[0014] Furthermore, the adjustment plate includes an arc-shaped plate with an opening facing outward, and a pressure plate vertically arranged on the arc-shaped plate; the paddle plate group can contact the arc-shaped plate; the central shaft is rotationally connected to the mounting plate through a torsion spring;

[0015] Description: The arc-shaped plate used in the above-mentioned method can better contact with the paddle group, thereby improving the effect of the paddle group. The pressure plate can contact with the inner wall of the mixing box during movement to further squeeze the agglomerated materials inside the heating chamber, effectively reducing the agglomeration rate of refractory mud prepared by using this device; and the central axis and the mounting plate are connected by a torsion spring rod, which can enable the central axis to reset after a forward / reverse rotation, so as to facilitate rotation and resetting in the other direction under the action of the driving member of the other crushing roller. The setting of the torsion spring rod further enhances the disturbing effect of the paddle group on the material, thereby improving the mixing effect.

[0016] Further, the paddle assembly is arranged at the lower half of the central axis;

[0017] Note: The above setting can prevent the paddle assembly from contacting the heating rod, thereby affecting the heating effect of the heating rod.

[0018] Furthermore, the driving member includes a mounting ring fixedly arranged on the crushing roller, and a shifting block mounted on the outer end of the mounting ring; the shifting block is an L-shaped structure;

[0019] Note: The above arrangement can make the crushing roller drive the heating component more efficiently, further improve the heating efficiency, and make the refractory mud mixed more fully.

[0020] The beneficial effects of the utility model are:

[0021] (1) The utility model realizes pre-crushing of materials by setting a crushing roller, so that large pieces of materials are crushed into relatively small ones, effectively reducing the agglomeration phenomenon in the refractory mud production process, and utilizes the forward and reverse reciprocating drive of the threaded tube by the driving member to realize efficient adjustment of the heating position of the heating rod inside the mixing device, further improving the heating efficiency, thereby reducing the agglomeration phenomenon of the refractory mud.

[0022] (2) The utility model can achieve mixing and extrusion of materials during the heating process through the synergistic effect of the transmission belt, the mixing component and the heating component, further reducing the probability of agglomerates in the materials, thereby effectively improving the mixing effect of the device.

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below in conjunction with specific implementation methods to better reflect the advantages of the present invention.

[0033] Example 1

[0034] like Figure 1 , Figure 2 The mixing device for making anti-caking refractory mud shown in the figure comprises a mixing box 1, and a crushing component 2, a heating component 3 and a mixing component 4 which are arranged in the mixing box 1 from top to bottom; the mixing component 4 adopts two commercially available electric stirring rods;

[0035] The mixing box 1 includes a heating chamber 11 for placing the heating assembly 3, and a crushing chamber 12 which is arranged on the heating chamber 11 and has an arc-shaped bottom. A feed port 13 is arranged at the top of the crushing chamber 12. A discharge port 14 is arranged at the bottom of the heating chamber 11, and a solenoid valve for controlling the opening and closing of the discharge port 14 is arranged at the discharge port 14.

[0036] like Figure 3 As shown, the crushing assembly 2 includes two crushing rollers 21 rotatably arranged in the mixing box 1 and meshing with each other, and two driving members 22 respectively fixedly arranged on one end of the rotating shaft of the corresponding crushing rollers 21; the two rotating shafts are respectively connected to the output end of the motor for driving the crushing rollers 21 to rotate; the motors are respectively arranged on the inner wall of the mixing box 1;

[0037] like Figure 4 As shown, the driving member 22 includes a mounting ring fixedly mounted on the crushing roller 21, and a shifting block 221 mounted on the outer end of the mounting ring; the shifting block 221 is an L-shaped structure;

[0038] like Figure 5 , Figure 6As shown, the heating assembly 3 includes a threaded tube 31 rotatably arranged in the mixing box 1 and located below the middle of the two crushing rollers 21, a plurality of heating rods 32 threadedly connected to the threaded tube 31, a mounting plate 33 fixedly sleeved on one end of the threaded tube 31, and a plurality of convex columns 34 circumferentially spaced and arranged on the mounting plate 33; the driving member 22 is in contact with the convex columns 34;

[0039] It should be noted that the heating rod and the solenoid valve mentioned in this embodiment are commercially available, and this embodiment also includes a power supply device for providing electrical energy to the motor, the heating rod, and the solenoid valve.

[0040] The working principle of this embodiment is as follows: the material to be mixed is passed through the feed port and enters the mixing box 1, and the motor driving the crushing roller 21 is started, and the crushing assembly 2 in the crushing chamber 12 is crushed into materials of similar size. As the two crushing rollers 21 rotate towards each other, the driving member 22 is driven to rotate, and the rotation of the driving member 22 can alternately drive the protruding column 34 on the mounting plate 33, so that the threaded tube 31 reciprocates in forward and reverse directions, so that the heating rod 32 is offset along the length direction of the threaded tube 31, further improving the heating effect on the material, thereby further reducing the agglomeration of the material during mixing, and at the same time starting the mixing assembly 4 to achieve full mixing of the material, thereby improving the mixing uniformity of the device and reducing the agglomeration rate.

[0041] Example 2

[0042] Different from Example 1, Figure 7 , Figure 8 As shown, the mixing assembly 4 includes a mounting plate 41 disposed on the side wall of the mixing box 1, a central shaft 42 rotatably disposed at the center of the mounting plate 41 and connected to the threaded tube 31 through a transmission belt, two spring rods 43 symmetrically disposed and connected to the mounting plate 41 at one end, two adjustment plates 44 respectively slidably disposed in the slide grooves on the side wall of the mixing box 1 through sliders and connected to the other ends of the spring rods 43, and a paddle group 45 disposed on the central shaft 42 and capable of contacting the adjustment plate 44; the paddle group 45 includes three paddles spaced apart along the length direction of the central shaft;

[0043] The adjusting plate 44 includes an arc-shaped plate 441 with an opening facing outward, and a pressing plate 442 vertically arranged on the arc-shaped plate 441; the paddle assembly 45 can contact the arc-shaped plate 441; the central shaft 42 is rotationally connected to the mounting plate 41 through a torsion spring;

[0044] The paddle assembly 45 is disposed at the lower half of the central axis 42 , and in this embodiment, the angle between the paddle assembly 45 and the vertical symmetry axis of the central axis 42 is 60°;

[0045] The working principle of this embodiment is basically the same as that of embodiment 1, except that a transmission belt is used to connect the heating component 3 and the mixing component 4, so that the heating component 3 drives the central shaft 42 while rotating, and the paddle group 45 on the central shaft drives the arc plate 441, so that the arc plate 441 performs horizontal reciprocating motion at the bottom of the mixing box 1, thereby enhancing the disturbing effect on the material. At the same time, during the movement of the arc plate 441, the pressing plate 442 can drive part of the material to one side and squeeze it, further reducing the agglomeration rate of the device, and then under the action of the torsion spring rod, the central shaft 42 and the paddle group 45 are reset, and then under the action of the crushing roller 21 on the other side, the material on the other side is processed. The above structure has a mixing effect and a pressing function, thereby significantly reducing the agglomeration rate of the device.
