Description

Technical Field

[0001] This application relates to the field of coating production technology, and in particular to a coating production device for preventing caking. Background Technology

[0002] In the production of coatings, chemicals, building materials and other industries, it is necessary to mix and disperse solid powders and liquid raw materials to prepare homogeneous slurries. The dispersing machine is the basic equipment for this process. Its core structure includes a tank, a motor installed on the top of the tank and a stirring rod connected to the output end of the motor. The motor drives the stirring rod to rotate and generate mechanical force to break up the agglomeration of powder and achieve preliminary mixing of solid and liquid. The existing technology has the following problems: When feeding materials into the existing dispersing machine, it is mostly done by directly feeding the material through an open or gravity funnel. Due to the difference in the fluidity of the powder itself and the humid storage environment, the powder is prone to clumping. At the same time, relying solely on the single rotation of the stirring rod, the liquid raw material is difficult to spread quickly after being added at once. The powder is prone to floating on the liquid surface or sinking to the bottom of the tank to form a dry powder layer and a sediment layer, resulting in uneven solid-liquid contact and incomplete wetting.

[0005] In one embodiment, the mixing box is a composite cavity structure with an upper cylinder and a lower cone, including a mounting box. The bottom of the mounting box is integrally formed with a mixing box, and a discharge pipe is fixedly installed at the bottom of the mixing box. The mounting box, the mixing box, and the discharge pipe are internally interconnected.

An embedding hole is provided through the outer wall of the mounting box. A nozzle is sealed and inserted into the embedding hole. The end of the nozzle away from the branch pipe extends out of the embedding hole and into the interior of the mounting box.

[0006] In one embodiment, the diverter pipe is a Y-shaped tee pipe structure, with its top inlet sealed to the outlet of the connecting pipe, and its two bottom outlets sealed to the two branch pipes respectively.

[0007] In one embodiment, two embedding holes are provided, which are symmetrically inclined and penetrate the outer wall of the mounting box; the nozzles at the discharge ends of the two branch pipes are respectively sealed and inserted into the two embedding holes.

Combined with the rotating vortex formed by the symmetrical impact of the double nozzles in the mixing tank through the 20° inclined embedded holes, the powder is fully wrapped and moistened by high-pressure slurry before entering the tank, effectively avoiding the formation of dry powder layer and sediment layer. Meanwhile, the conical structure of the mixing tank can extend the mixing path and further enhance the uniformity of solid-liquid wetting. Combined with the secondary homogenization of the stirring rod inside the tank, it makes up for the shortcomings of the existing technology that only relies on the single rotation of the stirring rod and the slow liquid diffusion. This application improves the anti-caking effect and slurry uniformity while shortening the overall mixing time and increasing production efficiency. Attached Figure Description

[0020] Reference Figure 1 A coating production equipment for preventing caking includes a tank 1 and an anti-caking structure 4. The tank 1 is used to contain coating raw materials and provides a closed space for stirring, mixing and material circulation.

[0021] The top of the tank body 1 is provided with a tank cover 2, which is used to seal the tank body 1, prevent dust and raw material volatilization, and provide an installation position for the motor 3, mixing box 41 and support frame 437.

[0022] A motor 3 is fixedly installed in the middle of the top of the can lid 2. The output end of the motor 3 passes through the can lid 2 and is fixedly connected to the stirring rod inside the can body 1. The motor 3 is used to drive the stirring rod to rotate at high speed, apply stirring force to the slurry in the can body 1, and promote the uniform mixing of slurry and powder inside the can body 1.

[0023] The anti-caking structure 4 is located at the top of the tank 1. The anti-caking structure 4 allows the powder to be fully moistened before entering the tank 1, effectively preventing clumping.

[0024] In one embodiment, reference is made to Figures 2-4 The anti-caking structure 4 includes a mixing box 41, a screw conveyor 42 and a pump body 43. The mixing box 41 is fixedly installed on the top of the tank cover 2 and is arranged to avoid space with the motor 3. The bottom of the mixing box 41 penetrates the tank cover 2 and extends into the tank body 1. The mixing box 41 is used to provide a closed mixing space for the powder conveyed by the screw conveyor 42 and the circulating slurry sprayed by the nozzle 436, so as to wet the powder and prevent the powder from agglomerating and clumping. The screw conveyor 42 can forcefully push powder through the rotation of the spiral blades, so as to achieve continuous and uniform feeding of powder, avoid local overload and agglomeration caused by too much material and too little liquid, and at the same time, the enclosed conveying structure prevents dust. Pump body 43 is used to provide high pressure to extract the slurry from the bottom of tank 1 and transport it to mixing tank 41 through pipeline; It should be noted that both the screw conveyor 42 and the pump body 43 are existing technologies, and their specific structures and principles will not be described in detail.

[0025] A feed hopper 421 is fixedly installed at the top of the feed end of the screw conveyor 42. By setting the feed hopper 421, it is convenient to add powder manually or automatically. In this embodiment, a feed grid is set inside the feed hopper 421, which can effectively prevent the accumulation of powder.

[0026] The bottom of the discharge end is fixedly installed with a discharge pipe 422. The bottom of the discharge pipe 422 is embedded and sealed in the middle of the top of the mixing box 41, and the two are connected internally. The discharge pipe 422 is used to accurately deliver the powder pushed by the screw conveyor 42 into the mixing box 41, ensuring that all the powder enters the closed mixing space for wetting.

[0027] A feed pipe 431 is fixedly installed at the feed inlet of the pump body 43. One end of the feed pipe 431 is sealed to the feed inlet of the pump body 43, and the other end passes through the bottom of the outer wall of the tank 1 and communicates with the inside of the tank 1. The feed pipe 431 is the extraction channel for circulating slurry.

[0028] A conveying pipe 432 is fixedly installed at the discharge port of the pump body 43. The conveying pipe 432 is the main conveying channel for high-pressure slurry and is used to guide the slurry output from the pump body 43 to the connecting pipe 433.

[0029] A connecting pipe 433 is fixedly connected to the end of the delivery pipe 432 away from the pump body 43. The connecting pipe 433 serves as a pipe turning and connecting component, used to connect the delivery pipe 432 and the diversion pipe 434.

[0030] A diversion pipe 434 is fixedly installed at the discharge end of the connecting pipe 433. The diversion pipe 434 is used to guide the slurry in the conveying pipe 432 into the branch pipe 435.

[0031] The outlet end of the diversion pipe 434 is bifurcated and connected to a branch pipe 435, which is used to guide the slurry distributed by the diversion pipe 434 to the corresponding nozzle 436.

[0032] A nozzle 436 is fixedly connected to the discharge end of the branch pipe 435. The end of the nozzle 436 away from the branch pipe 435 penetrates the outer wall of the mixing box 41 and extends into its interior. The nozzle 436 is used to spray the slurry conveyed by the branch pipe 435 at high pressure, forming a counter-current vortex in the mixing box 41, quickly enveloping and wetting the powder, and preventing the powder from clumping.

[0033] In one embodiment, reference is made to Figure 5 The mixing box 41 is a composite cavity structure with an upper cylinder and a lower cone, including a mounting box 411. The mounting box 411 is used to provide a reference for the opening of the feed inlet 414 and the installation of the nozzle 436, and at the same time, it works with the mixing box 412 to form a closed mixing space to wet the powder.

[0034] The bottom of the mounting box 411 is integrally formed with a mixing box 412. In this embodiment, the mixing box 412 has a conical structure. The conical structure can guide the wetted slurry to flow downward, avoid the slurry from accumulating and stagnating in the mixing space, and at the same time extend the mixing path and improve the uniformity of wetting.

[0035] A discharge pipe 413 is fixedly installed at the bottom of the mixing box 412. The installation box 411, the mixing box 412 and the discharge pipe 413 are interconnected. The bottom of the discharge pipe 413 passes through the top of the tank cover 2 and is arranged to avoid space with the motor 3, extending into the tank body 1. The discharge pipe 413 is used to transport the wetted powder into the tank body 1. The top center of the mounting box 411 has a through-hole 414. The inlet 414 is embedded and sealed to the outlet pipe 422 and is internally connected. The inlet 414 provides an entrance channel for powder to enter the mounting box 411. Through the embedded and sealed connection with the outlet pipe 422, the powder conveying channel is sealed to prevent dust leakage.

[0036] An embedding hole 415 is provided through the outer wall of the mounting box 411 to fix the nozzle 436 and ensure the installation is sealed.

[0037] A nozzle 436 is sealed inside the embedded hole 415. The end of the nozzle 436 away from the branch pipe 435 extends out of the embedded hole 415 and into the mounting box 411. The nozzle 436 is used to spray out the high-pressure circulating slurry conveyed by the branch pipe 435. By wetting the powder with the slurry, the possibility of agglomeration is reduced.

[0038] In one embodiment, reference is made to Figure 4 The diversion pipe 434 has a Y-shaped three-way pipe structure. Its top inlet is sealed to the outlet of the connecting pipe 433, and its two bottom outlets are sealed to the two branch pipes 435 respectively. The symmetrical structure of the Y-type three-way pipe can accurately divide the single-channel high-pressure slurry transported by the connecting pipe 433 into two slurries with uniform flow and consistent pressure, ensuring that the two branch pipes 435 and the corresponding nozzles 436 can obtain the same jetting power, thereby forming a symmetrical opposing vortex inside the installation box 411, achieving all-round wrapping and full wetting of the falling powder, and avoiding the powder from clumping due to uneven wetting. Meanwhile, the smooth pipeline design of the Y-shaped structure can reduce the flow resistance of the slurry and prevent the slurry from accumulating and stagnating at the branch point.

[0039] There are two embedding holes 415, which are symmetrically inclined and pass through the outer wall of the mounting box 411; the nozzles 436 at the discharge end of the two branch pipes 435 are respectively sealed and passed through the two embedding holes 415. Two symmetrically distributed embedding holes 415 provide a precise installation position for the nozzles 436, ensuring that the nozzles 436 are symmetrically arranged in the mounting box 411. This allows the high-pressure slurry sprayed by the two nozzles 436 to form an opposing vortex in the central area of ​​the mounting box 411. By utilizing the shearing force and wrapping force of the high-speed material flow, the metered powder falling vertically from the feed inlet 414 is fully wrapped, avoiding local accumulation or insufficient wetting of the powder.

[0040] The embedding hole 415 is inclined at an angle of 15°-30° to the radial plane of the mounting box 411. In this embodiment, the embedding hole 415 is inclined at an angle of 20° to the radial plane of the mounting box 411. The 20° inclination angle allows the high-pressure slurry sprayed by the two symmetrically installed nozzles 436 to form a rotating counter-current vortex with moderate strength and comprehensive coverage in the central area of ​​the mounting box 411. When the powder conveyed by the screw conveyor 42 falls vertically from the feed port 414, the continuous shearing force and encapsulation force generated by the vortex will quickly break the initial agglomeration of the powder, while allowing the powder particles to fully contact the slurry, ensuring that the powder is uniformly wetted.

[0041] In one embodiment, reference is made to Figure 6 A support frame 437 is fixedly connected to the outside of the connecting pipe 433. One end of the support frame 437 is fixedly connected to the outside of the connecting pipe 433, and the other end is fixedly installed on the top of the tank cover 2, which is arranged to avoid space with the motor 3 and the mixing box 41. The support frame 437 is used to counteract the pipeline vibration and impact force generated during high-pressure slurry transportation, and to prevent loosening or sealing failure at the connection between the connecting pipe 433 and the conveying pipe 432 and the diversion pipe 434, so as to ensure the stable operation of the circulation pipeline.

[0042] In one embodiment, reference is made to Figure 6 The support frame 437 includes a base 4371, which is fixedly installed on the top of the can lid 2 and is arranged to avoid space between the motor 3 and the mixing box 41. The base 4371 is used to transfer the overall weight of the support frame 437 and the load of the connecting pipe 433 to the can lid 2, and to achieve stable installation by utilizing the structural strength of the can lid 2.

[0043] A support rod 4372 is fixedly connected to the top center of the base 4371. The support rod 4372 enables the fixing ring 4374 to adapt to the installation height of the connecting pipe 433, and at the same time resists the vibration and lateral force of the connecting pipe 433 through its own rigid structure.

[0044] A connecting block 4373 is fixedly connected to the top of the support rod 4372. The connecting block 4373 is the connecting component between the support rod 4372 and the fixing ring 4374. It is used to transfer the load of the connecting pipe 433 borne by the fixing ring 4374 to the support rod 4372, and at the same time provide an installation position for the fixing ring 4374.

[0045] A fixing ring 4374 is fixedly installed at the top of the connecting block 4373. The fixing ring 4374 nests and hugs the outside of the connecting pipe 433 to achieve rigid support for the connecting pipe 433. The rigid connection with the connecting pipe 433 is achieved through the nesting and hugging fixing method. This can not only limit the axial and radial displacement of the connecting pipe 433, but also transmit the vibration and load of the connecting pipe 433 to the support rod 4372 and the base 4371, and finally distribute the load through the can cover 2.

[0046] Working principle: During operation, the basic liquid coating raw material is first injected into the tank 1, and the tank cover 2 is sealed for protection. The motor 3 is started to drive the stirring rod to rotate at low speed to form convection. Then, the powder is fed into the feed hopper 421 of the screw conveyor 42. After being buffered by the feed grid, the screw conveyor feeds the powder quantitatively and continuously through the discharge pipe 422 into the installation box 411 of the mixing box 41 by rotating the spiral blades. The pump body 43, which starts simultaneously, draws the slurry from the bottom of the tank through the feed pipe 431 and transports it to the Y-type diversion pipe 434 through the conveying pipe 432 and the connecting pipe 433. During the conveying, the connecting pipe 433 is rigidly fixed by the support frame 437 to ensure the stability of the pipeline. After the slurry is evenly distributed to two branch pipes 435, the nozzles 436, which are symmetrically installed at a 20° angle to the radial plane of the mounting box 411, spray high-pressure slurry towards the center of the mounting box 411, forming a rotating counter-current vortex that quickly envelops and wets the falling powder. The wetted slurry enters the tank 1 through the mixing box 412 and the discharge pipe 413. The motor 3 drives the stirring rod to rotate at high speed to achieve homogeneous mixing of the slurry and the raw materials in the tank. At the same time, the pump 43 continuously draws slurry from the bottom of the tank 1 and circulates it to the mixing box 41, which greatly reduces the possibility of powder agglomeration and ensures the uniformity of coating mixing.
