Description

Technical Field

[0001] This utility model relates to the technical field of mortar mixing devices, specifically a mixing device for antistatic and fireproof mortar. Background Technology

[0002] Antistatic and fireproof mortar is a special building material that combines antistatic and fireproof functions. It is mainly used in places where it is necessary to prevent static electricity accumulation and resist fire risks simultaneously (such as electronics factories, laboratories, flammable and explosive warehouses, etc.). Its composition and cost are roughly as follows:

[0003] By adding conductive materials (such as carbon fiber, graphite, metal powder, etc.), the surface resistivity of the mortar is reduced to \(10^4\sim 10^6 \Omega\), effectively dissipating static electricity and preventing accidents caused by electrostatic sparks.

[0004] By incorporating flame retardants (such as aluminum hydroxide, vermiculite, perlite) or high-temperature resistant aggregates, the fire resistance limit of the mortar can be improved (usually ≥2 hours), achieving the Class A fire protection standard (non-combustible material).

[0005] In the process of mixing antistatic and fireproof mortar, the addition of conductive materials (such as carbon fiber, graphite, metal powder, etc.) is usually done by manual pouring. During this process, a shaking operation is performed to disperse the conductive materials and achieve the effect of spreading the materials out, avoiding the situation where they cannot be dispersed and clump together due to one-time pouring. Based on this, in order to simplify this material feeding operation and further reduce the workload of workers, a mixing device for antistatic and fireproof mortar is provided. Utility Model Content

[0030] 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.

[0031] Please see Figures 1-3In this embodiment of the present invention, a mixing device for antistatic and fireproof mortar includes a mixing assembly 1 consisting of a mixing tank 101, a reduction motor 102, a rotating shaft 103, a cross connector 104, and mixing arms 105. The reduction motor 102 is installed at the bottom of the mixing tank 101, and the output end of the reduction motor 102 extends into the interior of the mixing tank 101 and is fixedly connected to the rotating shaft 103. The cross connector 104 is fixedly connected to the top of the rotating shaft 103. Multiple mixing arms 105 are provided, and the multiple mixing arms 105 are arranged in a ring around the rotating shaft 103 and fixedly fixed to the bottom of the cross connector 104. A feeding assembly 2 is provided on the outside of the mixing tank 101 and the top of the cross connector 104. The feeding assembly 2 is used to realize the scattered feeding operation of materials.

[0032] The feeding assembly 2 includes a feeding unit and a reciprocating unit;

[0033] The feeding unit is used to guide and shake off materials during feeding.

[0034] The reciprocating unit provides power for the shaking operation of the feeding unit;

[0035] The feeding unit includes a feeding hopper 201, a support rod 202, a fixed base 203, a guide rail 204, a limiting slide plate 205, a material frame 206, and a mesh plate 207;

[0036] The feeding hopper 201 is located on the upper outer side of the mixing tank 101 and extends obliquely to the upper part of the opening of the mixing tank 101;

[0037] The fixed base 203 is welded and fixed to the outside of the mixing tank 101. Multiple support rods 202 are provided. Multiple support rods 202 are fixed to the lower surface of the feeding hopper 201 and welded to the top of the fixed base 203 to achieve fixed support for the feeding hopper 201.

[0038] There are two guide rails 204, which are symmetrically fixed at both ends of the bottom of the feeding hopper 201, and one side of the guide rail 204 is fixedly connected to the support rod 202.

[0039] The limiting slide plate 205 is fixed to the top of the material frame 206, and the grid plate 207 is installed on the inner bottom of the material frame 206. The material frame 206 is distributed in the middle of the two guide rails 204 and is horizontally slidably connected to the guide rails 204 through the limiting slide plate 205.

[0040] The material inside the hopper 201 can slide down to the inside of the material frame 206 and be supported by the grid plate 207. Through the reciprocating movement of the limiting slide plate 205 and the material frame 206, the material is dispersed and falls downward through the holes of the grid plate 207.

[0041] The reciprocating unit includes a connecting arm 208, a straight groove ring block 209, and an eccentric column 210;

[0042] The connecting arm 208 is fixed to one side of the material frame 206 and extends above the cross connecting seat 104, and the straight groove ring block 209 is fixed to the side of the connecting arm 208 away from the material frame 206;

[0043] The eccentric column 210 is fixed at the top eccentric position of the cross connector 104, and the straight groove ring block 209 is sleeved on the outside of the eccentric column 210.

[0044] In this embodiment, the operation method for mixing and stirring antistatic and fireproof mortar using this mixing device is as follows:

[0045] Most of the raw materials for the mortar (such as aggregates and flame retardants) can be poured into the mixing tank 101 by manual labor or mechanical devices (such as loader) to avoid direct pouring. Add an appropriate amount of water and mix. At this time, start the reduction motor 102. The reduction motor drives the rotating shaft 103 and the cross connecting seat 104 to rotate. The cross connecting seat 104 drives the mixing arm 105 to rotate in a circle to realize the mixing operation of the raw materials.

[0046] During this process, conductive materials can be fed through the feeding component 2. The conductive materials are poured into the feeding hopper 201 (it should be noted that the feeding hopper 201 has a certain height and can temporarily store the conductive materials). At this time, the conductive materials slide down through the limiting slide plate 205 and fall into the material frame 206 (it should be noted that the limiting slide plate 205 has a through structure in the middle).

[0047] The mesh plate 207 can intercept conductive materials, preventing them from falling off all at once. Some conductive materials will fall into the mixing tank 101 through the gaps in the mesh plate 207.

[0048] At the same time, the rotation of the cross connecting seat 104 drives the eccentric column 209 to rotate in a circular motion. The eccentric column 209, which rotates in a circular motion, cooperates with the straight groove ring block 208 to realize the reciprocating movement of the connecting arm 208, which in turn causes the material frame 206, the limiting slide plate 205, and the grid plate 207 to slide back and forth as a whole. The reciprocating grid plate 207 is similar to a "sieve" structure, which allows the conductive material to be screened off, thus realizing the dispersion and dropping of the conductive material.

[0049] The combination of these multiple components replaces the traditional manual operation of shaking and pouring conductive materials, further reducing the workload of workers.

[0050] Please refer to this carefully. Figures 1-3 The inner wall dimensions of the limiting slide plate 205 are matched with the inner wall dimensions of the material frame 206 and the bottom port dimensions of the feeding hopper 201;

[0051] The outer wall dimension of the limiting slide plate 205 is larger than the outer wall dimension of the feeding hopper 201;

[0052] The bottom horizontal height of the material frame 206 is higher than the top horizontal height of the cross connector 104, and the moving area of ​​the material frame 206 is located above the opening of the mixing tank 101.

[0053] In this embodiment: during the reciprocating movement of the material frame 206, the bottom port of the feeding hopper 201 can be blocked by the limiting slide plate 205 to prevent the material from falling out due to the gap space between the bottom of the feeding hopper 201 and the material frame 206.

[0054] Furthermore, the material frame 206 will not interfere with the cross connector 104 during its reciprocating movement.

[0055] Please refer to this carefully. Figures 1-2 An L-shaped reinforcing arm 211 is also fixed to the top of the fixed base 203. The L-shaped reinforcing arm 211 extends to the side end face of the guide rail 204 away from the support rod 202 and is fixedly connected to the fixed base 203.

[0056] In this embodiment, the L-shaped reinforcing arm 211 can increase the support strength of the guide rail 204, thereby ensuring the stability of the reciprocating movement of the material frame 206.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
