Description

Technical Field

[0001] The utility model relates to the field of preparation of thermal insulation mortar materials, in particular to a mixing device for foam particle thermal insulation mortar materials. Background Art

[0002] Adding foam particles with thermal insulation functions such as polystyrene to cement mortar can effectively improve the thermal insulation performance of panels such as decorative panels prepared from cement mortar. The particle size of these foam particles is generally between 1 and 5 mm. However, when mixing foam particles into cement mortar, there is often a problem that the two are not easily mixed evenly, resulting in uneven distribution of foam particles in the cement mortar. This is because the density of the foam particles is small and the mass is light, while the density of the cement mortar is large. Coupled with the poor affinity between the surface of the foam particles and water, the foam particles are prone to float on the upper part of the cement mortar during the stirring and mixing process and are difficult to be evenly dispersed in the cement mortar, thus resulting in uneven thermal insulation performance of the manufactured thermal insulation board and the quality being difficult to guarantee. Content of the Utility Model

[0003] Aiming at the above problems, the utility model provides a mixing device for foam particle thermal insulation mortar materials, which can effectively improve the dispersion uniformity of foam particles in cement mortar and improve the quality of thermal insulation boards. Specifically, the utility model discloses the following technical solutions.

[0004] A mixing device for foam particle thermal insulation mortar materials, comprising: a vertical mixing tank, a screw conveyor, a motor, a mixing pipe, a vertical shaft, screw blades, a transparent window and a photoelectric sensor. Among them: the screw conveyor is horizontally arranged, and its discharge end is communicated with the inner cavity of the vertical mixing tank, and the screw conveyor is provided with a cement-based material inlet and a foam particle inlet. The motor is arranged above the vertical mixing tank, and the mixing pipe is vertically arranged in the vertical mixing tank. The vertical shaft is vertically arranged in the mixing pipe and is connected to the motor at the upper end. The screw blades are fixed on the vertical shaft, and the lower end of the screw blades is located below the lower end of the mixing pipe. There are two transparent windows, which are symmetrically arranged on the side walls of the vertical mixing tank respectively, and the transparent windows are located between the discharge end of the screw conveyor and the upper port of the mixing pipe, and the transparent windows are located on the side of the discharge end of the screw conveyor. The transmitter and receiver of the photoelectric sensor are respectively arranged outside the two transparent windows, and the transmitter and receiver are opposite to each other. The receiver is connected to the controller of the motor.

[0005] Further, a spray pipe is arranged in the vertical mixing tank, and it is located above the discharge end of the screw conveyor. Preferably, the bottom surface of the vertical mixing tank is of a conical or arc-shaped structure, and it has a discharge port at the bottom.

[0006] Further, it further includes a vertically arranged support pipe base, and the support pipe base is suspended and supported on the bottom surface of the vertical stirring tank through a support rod. The lower end of the mixing pipe is fixed in the "T"-shaped pipe orifice of the support pipe base.

[0007] Further, it further includes a stirring frame, the end of the upper frame of which is fixedly connected to the vertical shaft above the mixing pipe, and the side frame of the stirring frame is located between the mixing pipe and the inner side wall of the vertical stirring tank.

[0008] Further, the end of the lower frame of the stirring frame is connected with an arc-shaped plate, and the arc-shaped plate is attached to the outer side wall of the mixing pipe. Preferably, the arc-shaped plate is supported on the upper end surface of the support pipe base.

[0011] Compared with the prior art, the present utility model has at least achieved the following beneficial effects: The mixing device for the foam particle thermal insulation mortar material first gradually adds foam particles to the cement-based material being conveyed into the vertical stirring tank through the auger conveyor to premix the two, improving the dispersibility of the foam particles. The cement-based material dispersed with foam particles is gradually conveyed into the vertical stirring tank under the action of the auger conveyor. Meanwhile, the spray pipe sprays mixing water, and the vertical shaft drives the auger blades to convey the mortar material at the bottom of the vertical stirring tank upward through the mixing pipe, enabling the mortar material to be vertically circulated and stirred and mixed, improving the dispersion uniformity of the foam particles in the mortar material. As the mortar material in the vertical stirring tank increases, when it exceeds the upper port of the mixing pipe and blocks the light emitted by the emitter of the photoelectric sensor, the receiver transmits a signal to the controller to control the motor to reverse, so that the upper mortar material is conveyed to the bottom of the vertical stirring tank by the auger blades through the mixing pipe, preventing the foam particles from floating on the upper part of the mortar material and being difficult to disperse in the mortar material, and improving the dispersibility of the foam particles in the mortar material.

Detailed implementation manners

[0018] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanations of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present invention belongs.

[0019] For the convenience of narration, if terms such as "upper", "lower", "left", and "right" appear in the present invention, they only represent the same directions as the upper, lower, left, and right directions of the attached drawings themselves, and do not limit the structure. They are only for facilitating the description of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to needs to have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present invention.

[0020] Refer to Figure 1 and Figure 2 , which exemplifies a mixing device for foam particle thermal insulation mortar, including: a vertical mixing tank 1, an auger conveyor 2, a motor 3, a mixing pipe 4, a vertical shaft 5, an auger blade 6, a transparent window 7, and a photoelectric sensor. Specifically: The auger conveyor 2 is horizontally arranged, and its right end is the discharge end and is connected to the interface of the vertical mixing tank 1 so as to gradually feed the cement-based material into the inner cavity of the vertical mixing tank 1 for further mixing. The cement-based material is generally a dry powder material formed by cement powder and fine sand, and forms cement mortar after being mixed with water. The cement-based material feed inlet 201 and the foam particle feed inlet 202 are sequentially arranged on the auger conveyor 2 from left to right so as to feed the cement-based material into the auger conveyor 2 and then gradually add foam particles thereto. The bottom surface of the vertical mixing tank 1 is of a conical or arc-shaped structure, and it has a discharge port at the bottom so as to discharge the mixed mortar.

[0021] The motor 3 is arranged on the upper surface of the top cover of the vertical mixing tank 1, and the mixing tube 4 is arranged vertically in the vertical mixing tank 1. The mixing tube 4 is fixedly connected to the vertical mixing tank 1 through a connecting rod. The lower end of the mixing tube 4 is located above the bottom surface of the vertical mixing tank 1, and the upper end of the mixing tube 4 is located below the interface of the vertical mixing tank 1, that is, the mixing tube 4 is suspended. The vertical shaft 5 is arranged vertically in the mixing tube 4, and the upper end passes through the upper end of the mixing tube 4 and is connected to the motor 3. The auger blade 6 is fixed on the vertical shaft 5, and the lower end of the auger blade 6 is located below the lower end of the mixing tube 4, so that the motor 3 is used to drive the vertical shaft 5 and the auger blade 6 to rotate forward or reverse, thereby conveying and mixing cement mortar.

[0022] There are two transparent windows 7, which are symmetrically arranged on the side wall openings of the vertical mixing tank 1, and the transparent windows 7 are located between the discharge end of the dragon conveyor 2 and the upper end of the mixing pipe 4, and the transparent windows 7 are located on the side of the discharge end of the dragon conveyor 2 (such as Figure 2 As shown). The material of the transparent window 7 can be organic glass, tempered glass, plastic, etc. The transmitter 8 and receiver 9 of the photoelectric sensor are respectively arranged outside the two transparent windows 7, and are fixedly connected to the outer wall of the vertical mixing tank 1, and the transmitter 8 and the receiver 9 are facing each other, and the receiver 9 is connected to the controller 10 of the motor 3. The photoelectric sensor can be an existing product such as an infrared sensor, a laser sensor, etc., such as an elevator door opening and closing induction sensor, etc.

[0023] When in use, the dragon conveyor 2 first gradually adds the foam particles to the cement-based material. In the process of forward conveying, the auger blades of the dragon conveyor 2 play a preliminary premixing role for the cement-based material and the foam particles, thereby improving the dispersibility of the foam particles. The cement-based material dispersed with the foam particles is gradually conveyed to the vertical mixing tank 1 under the action of the dragon conveyor 2. At the same time, the spray pipe 11 in the vertical mixing tank 1 sprays mixing water downward. The spray pipe 11 is located above the discharge end of the dragon conveyor 2 and below the top wall of the vertical mixing tank 1.

[0024] The vertical shaft 5 drives the auger blade 6 to rotate, conveying the mortar material at the bottom of the vertical mixing tank 1 upward from the lower port of the mixing pipe 4, then discharging it from the upper port of the mixing pipe 4, and then re-entering the bottom of the vertical mixing tank 1, so that the mortar material is continuously circulated and mixed, improving the dispersion uniformity of the foam particles in the mortar material. As the amount of mortar material in the vertical mixing tank 1 increases and exceeds the upper port of the mixing pipe 4 (at this time, the auger conveyor 2 reaches the feeding time and automatically stops feeding), the mortar material blocks the light emitted by the emitter 8 of the photoelectric sensor, and the receiver 9 transmits this signal to the controller 10, and the controller controls the motor 3 to rotate in the reverse direction. At this time, the auger blade 6 also rotates in the reverse direction, and the mortar material in the upper part of the vertical mixing tank 1 can be conveyed downward through the upper port of the mixing pipe 4, so that the upper mortar material is conveyed to the bottom of the vertical mixing tank 1, realizing cyclic mixing, preventing the foam particles from floating on the upper part of the mortar material and being difficult to disperse in the mortar material, thereby effectively improving the dispersion of the foam particles in the mortar material.

[0025] After the mixing is completed, the discharge port at the bottom of the vertical mixing tank 1 is opened to discharge the mortar material. The spray pipe 11 can also be opened to clean the inside of the vertical mixing tank 1, and the cleaned water is discharged from the discharge port. The above mixing device of this embodiment forms a structure through the mixing pipe 4, the vertical shaft 5, the auger blade 6, the transparent window 7 and the photoelectric sensor to realize two different mixing methods, reducing the problem that the foam particles are easy to float on the upper part of the cement mortar and difficult to be evenly dispersed in the cement mortar, which in turn leads to uneven heat preservation performance of the manufactured heat preservation board.

[0026] Reference Figure 1 , in another embodiment, the cement-based material inlet 201 of the above-mentioned mixing device for foam particle thermal insulation mortar material is connected to the cement-based material storage tank 203, and the foam particle inlet 202 is connected to the foam particle storage tank 204. The cement-based material storage tank 203 is used to store the powdery cement-based material formed by the above-mentioned cement powder and fine sand. The foam particle storage tank 204 is used to store foam particles, such as polystyrene foam particles, etc. The cement-based material and foam particles are conveyed into the auger conveyor 2 in a set ratio (for example, the weight part ratio of cement powder: fine sand: foam particles is 1:2:3.5) through a conveying mechanism.

[0027] Reference Figure 1 and Figure 3, in another embodiment, the mixing device for the foam particle thermal insulation mortar material further includes a vertically arranged support pipe base 12. The support pipe base 12 is in a circular tubular shape, and its upper pipe orifice is a "T"-shaped pipe orifice. The support pipe base 12 is suspended and supported on the bottom surface of the vertical stirring tank 1 through a support rod 13. The lower end of the mixing pipe 4 is inserted into the "T"-shaped pipe orifice of the support pipe base 12 and the two are fixedly connected, and the lower end of the auger blade 6 is located below the lower port of the support pipe base 12. In this embodiment, the support pipe base 12 is used to replace the above-mentioned connecting rod to realize the suspended arrangement of the mixing pipe 4, so that a stirring frame 14 can be arranged outside the mixing pipe 4, and then the vertical shaft 5 is used to drive the stirring frame 14 to rotate to mix the mortar material outside the mixing pipe 4, improving the operation efficiency. Therefore, referring to Figure 1 , the end of the upper border of the stirring frame 14 is fixedly connected to the vertical shaft 5 above the mixing pipe 4, and the side border of the stirring frame 14 is located between the mixing pipe 4 and the inner side wall of the vertical stirring tank 1. The end of the lower border of the stirring frame 14 is located at the lower outer wall of the mixing pipe 4. The two stirring frames 14 are symmetrically arranged on both sides of the mixing pipe 4 to form a rectangular stirring frame.

[0028] Referring to Figure 1 and Figure 4 , in another embodiment, an arc-shaped plate 15 is connected to the end of the lower border of the stirring frame 14 of the mixing device for the foam particle thermal insulation mortar material, and the arc-shaped plate 15 is attached to the outer side wall of the mixing pipe 4, thereby improving the stability of the rotation of the stirring frame 14. In a more optimal embodiment, the arc-shaped plate 15 is supported on the upper end surface of the support pipe base 12, thereby further improving the stability of the rotation of the stirring frame 14.

[0029] Referring to Figure 1 , in another embodiment, a cross plate 16 is also fixedly connected to the side border of the stirring frame 14 of the mixing device for the foam particle thermal insulation mortar material, and the other end of the cross plate 16 is attached to the inner side wall of the vertical stirring tank 1. Through the cooperation of the cross plate 16 and the lower border of the mixing frame 14, it not only helps to further improve the stability of the rotation of the stirring frame 14, but also helps to improve the mixing efficiency.

[0030] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
