Description

Technical Field

[0001] This utility model belongs to the technical field of building waterproof material coating production equipment, and particularly relates to a shaftless stirring device and coating production equipment. Background Technology

[0002] Currently, the commonly used stirring devices in the coating production industry consist of a motor-driven stirring shaft that mixes materials inside the reaction vessel to meet production process requirements. However, this shaft-driven system necessitates openings in the vessel body for installation and requires sealing devices to maintain the shaft's position. Wear and failure of these seals can lead to insufficient vacuum levels within the reaction vessel, resulting in product quality fluctuations, increased risk of defective products, and high maintenance costs. Furthermore, existing shaft-driven stirring devices exhibit poor mixing efficiency, excessively long reaction times, and high energy consumption. Utility Model Content

[0003] The main purpose of this utility model is to propose a shaftless stirring device and a coating production equipment, which aims to solve the technical problem that the sealing device of the coating stirring shaft is prone to failure due to wear in the prior art.

[0004] To achieve the above objectives, this utility model provides a shaftless stirring device for stirring materials in a reaction vessel. The shaftless stirring device is housed in the reaction vessel and includes: a mounting base for connecting the reaction vessel; a pump-jet motor mounted on the top of the mounting base and having a rotating chamber, the mounting base having a material passage hole connecting the inlet of the reaction vessel and the rotating chamber, the material passage hole being used to allow materials to enter the rotating chamber through the inlet; and a vortex guide generator connected to the pump-jet motor, the vortex guide generator having a feed channel and a diffusion channel, the feed channel connecting the diffusion channel and the outlet of the rotating chamber, the diffusion channel being used to spray materials outwards.

[0005] In this embodiment of the utility model, the mounting base includes: a base plate with a discharge port communicating with the reactor, the bottom of the base plate being connected to the bottom of the reactor; a support plate, a plurality of support plates being spaced apart on the top of the base plate along the circumference of the base plate, a material passage hole for material passage being formed between any two adjacent support plates, and the pump motor being connected to the top of the support plate.

[0006] In this embodiment of the utility model, the cross-section of the support plate is trapezoidal, and the large end of the support plate is connected to the base plate, while the small end is connected to the pump-jet motor.

[0007] In this embodiment of the invention, the vortex guide generator includes multiple helical blades, which form a feeding channel for feeding, and a diffusion channel for discharging is formed between any two adjacent helical blades.

[0008] In this embodiment of the invention, the diffusion channel is arranged to gradually expand from the inside to the outside.

[0009] In this embodiment of the invention, the pump motor and the mounting base are detachably connected.

[0010] In this embodiment of the utility model, the pump-jet motor is detachably connected to the mounting base via a first flange plate with a first material outlet.

[0011] In this embodiment of the invention, the vortex guide generator and the pump-jet motor are detachably connected.

[0012] In this embodiment of the invention, the vortex guide generator is detachably connected to the pump-jet motor via a second flange plate with a second material outlet.

[0013] This utility model also proposes a coating production equipment, which includes a reaction vessel and a shaftless stirring device as described above.

[0014] Through the above technical solution, the shaftless stirring device provided by this utility model embodiment has the following beneficial effects: When the shaftless stirring device is working, the pump-jet motor rotates at high speed. Material enters the rotating chamber of the pump-jet motor through the material passage hole on the mounting base. After the pump-jet motor rotates and mixes the material in the rotating chamber, it enters the vortex guide generator through the feed channel. Under the diffusion effect of the diffusion channel, the vortex guide generator can spray and diffuse the material upwards and outwards at high speed. With the continuous operation of the pump-jet motor, the liquid material in the reactor forms a high-speed vortex motion, achieving dispersion and mixing of the material in the reactor. This invention utilizes a shaftless pump-jet motor in conjunction with a vortex guide generator to simultaneously realize the stirring and mixing processes. Due to the shaftless design, the coating reactor does not require a stirring shaft or sealing device, resulting in a continuous and stable sealing effect. This avoids the problem of vacuum affecting the material reaction and eliminates the need for maintenance and replacement of seals, reducing maintenance costs. Simultaneously, the pump-jet motor and vortex guide generator work together to achieve high-speed vortex motion of the material in the reactor, enhancing the stirring and agitation effect.

[0015] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0017] Explanation of reference numerals in the attached figures Detailed Implementation

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0019] The shaftless stirring device according to the present invention is described below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, in an embodiment of this utility model, the shaftless stirring device 100 is used for stirring materials in the reactor 210. The shaftless stirring device 100 is housed in the reactor 210 and includes a mounting base 1, a pump-jet motor 2, and a vortex guide generator 3. The mounting base 1 is used to connect the reactor 210. The pump-jet motor 2 is mounted on the top of the mounting base 1 and is provided with a rotating chamber 21. The mounting base 1 is provided with a feed hole 11, which connects the reactor 210 and the feed inlet of the rotating chamber 21. The feed hole 11 is used to allow materials to enter the rotating chamber 21 through the feed inlet. The vortex guide generator 3 is connected to the pump-jet motor 2. The vortex guide generator 3 is provided with a feed channel and a diffusion channel 31. The feed channel connects the diffusion channel 31 and the discharge port of the rotating chamber 21. The diffusion channel 31 is used to spray materials outward.

[0021] Understandably, the mounting base 1 can be welded to the reactor 210. The pump-jet motor 2 may include a motor housing 22 and a motor rotor 23 housed within the motor housing 22. The rotating chamber 21 is disposed within the motor rotor 23. When the pump-jet motor 2 is started, the rotating blades within the motor rotor 23 can drive the material within the rotating chamber 21 to rotate. The mounting base 1 and the vortex guide generator 3 can both be connected to the pump-jet motor 2 through the motor housing 22, facilitating the assembly of the shaftless stirring device 100. The pump-jet motor 2 can also adopt other existing shaftless motor structures capable of high-speed rotation of materials. The mounting base 1, the pump-jet motor 2, and the vortex guide generator 3 are connected sequentially from bottom to top. The shaftless stirring device 100 in this embodiment can be used for stirring coatings such as waterproof coatings.

[0022] In this embodiment, when the shaftless stirring device 100 is working, the pump-jet motor 2 rotates at high speed. The material can enter the rotating chamber 21 of the pump-jet motor 2 through the material passage 11 of the mounting base 1. After the pump-jet motor 2 rotates and mixes the material in the rotating chamber 21, it can enter the vortex guide generator 3 through the feed channel. Under the diffusion effect of the diffusion channel 31, the vortex guide generator 3 can spray the diffused material upward and outward at high speed. With the continuous operation of the pump-jet motor 2, the liquid material in the reaction vessel 210 forms a high-speed vortex motion, so that the material in the reaction vessel 210 is dispersed and mixed. In this embodiment, the shaftless pump-jet motor 2 and the vortex guide generator can simultaneously realize the stirring and mixing process. Due to the shaftless design, the coating reaction vessel 210 does not need to be designed with a stirring shaft and sealing device, so that the sealing effect of the reaction vessel 210 is continuous and stable, which can avoid the problem of vacuum affecting the material reaction, and there is no need to maintain and replace the sealing parts, reducing maintenance costs. At the same time, the pump-jet motor 2, in conjunction with the vortex guide generator, can also realize the high-speed vortex motion of materials in the reactor 210, and the high-speed stirring and mixing of materials can enhance the stirring and disturbance effect of materials.

[0023] Compared with traditional processes, the shaftless stirring device 100 in this embodiment maintains a stable vacuum level above 0.95 for a long period of time, and the material reaction stirring time is shortened by 12% compared with traditional stirring, thereby reducing energy consumption and improving production efficiency.

[0024] like Figure 2 As shown, the mounting base 1 includes a base plate 12 and a support plate 13. A discharge port 14 communicating with the reactor 210 is provided in the middle of the base plate 12. The bottom of the base plate 12 is used to connect with the bottom of the reactor 210, and the bottom of the reactor 210 can be discharged through the discharge port 14. Multiple support plates 13 are arranged at intervals along the circumference of the base plate 12 on the top of the base plate 12, and the multiple support plates 13 surround the discharge port 14. A material passage hole 11 for material passage is formed between any adjacent support plates 13. The pump spray motor 2 is connected to the top of the support plate 13. The number of support plates 13 can be set according to actual usage requirements. In one embodiment, the number of support plates 13 is three. The three support plates 13 are arranged at intervals along the circumference of the base plate 12. The base plate 12 can be a hollow circular plate with multiple material passage holes 11, which can simultaneously supply material to the pump-jet motor 2, so that the material on the side of the mounting base 1 can enter the rotating chamber 21 of the pump-jet motor 2 through the mounting base 1, ensuring the feeding efficiency of the material entering the pump-jet motor 2, and facilitating the discharge of material from the bottom of the reactor 210.

[0025] It should be noted that the cross-section of the support plate 13 is trapezoidal, and the large end of the support plate 13 is connected to the base plate 12, while the small end is connected to the pump spray motor 2. In this embodiment, the support plate 13 is a trapezoidal flat plate that is wider at the bottom and narrower at the top, and the outer side of the support plate 13 is provided with a bevel. The structure is simple while ensuring the support strength of the support plate 13.

[0026] In one embodiment, the vortex guide generator 3 includes multiple helical blades 32, which form a feed channel for feeding material, and a diffusion channel 31 for discharging material is formed between any two adjacent helical blades 32. In this embodiment, the number of helical blades 32 can be set according to actual usage requirements, such as... Figure 2 As shown, in this embodiment, there are six spiral blades 32. The six spiral blades 32 are arranged at intervals along the circumference of the second flange plate 5. The six diffusion channels 31 can simultaneously spray diffusion material to the outer periphery, which can greatly improve the material diffusion effect. The inclination angle between the axis of the spiral blades 32 and the second flange plate 5 is less than 90 degrees. The height of the reactor 210 is directly proportional to the inclination angle. The higher the reactor 210 is, the larger the inclination angle is.

[0027] Specifically, the diffusion channel 31 is arranged to gradually expand from the inside out. In this embodiment, the diffusion channel 31 is diffused from the center of the vortex guide generator 3 outward, which enables the material passing through the vortex guide generator 3 to be sprayed and diffused to the surroundings at high speed upward.

[0028] Understandably, the pump-jet motor 2 and the mounting base 1 are detachably connected. This detachable connection facilitates the maintenance and replacement of the pump-jet motor 2. In the event of a malfunction, the pump-jet motor 2 can be disassembled separately for inspection or replacement, making the shaftless mixing device 100 more convenient to use.

[0029] like Figure 2 As shown, the pump-jet motor 2 is detachably connected to the mounting base 1 via a first flange plate 4 with a first material outlet 41. In this embodiment, the first flange plate 4 can be a circular hollow flat plate, and the first flange plate 4 and the pump-jet motor 2 can be connected by multiple threaded fasteners such as screws or bolts. The threaded fasteners can be spaced apart along the circumference of the second flange plate 5.

[0030] Understandably, the vortex flow generator 3 and the pump-jet motor 2 are detachably connected. This detachable connection facilitates the maintenance and replacement of the vortex flow generator 3. In the event of a malfunction, the vortex flow generator 3 can be disassembled separately for inspection or replacement, making the shaftless stirring device 100 more convenient to use.

[0031] like Figure 2As shown, the vortex guide generator 3 is detachably connected to the pump-jet motor 2 via a second flange plate 5 with a second material outlet. In this embodiment, the second flange plate 5 can be a circular hollow plate, and the second flange plate 5 and the pump-jet motor 2 can be connected by multiple threaded fasteners such as screws or bolts. The threaded fasteners can be spaced apart along the circumference of the second flange plate 5.
