Description

Technical Field

[0001] This invention relates to the field of spray device technology, specifically to a high-pressure spray device for use in a combing workshop. Background Technology

[0002] In the carding workshop, the effectiveness of air spraying directly affects fabric quality and production efficiency. Insufficient spray volume can easily lead to yarn static electricity, breakage, and lint dispersion. Therefore, high-pressure spraying devices are widely used. Existing spraying devices mostly adopt a fixed nozzle structure, relying on motor-driven auxiliary diffusion, which has obvious drawbacks: First, motor-driven systems have high energy consumption and long-term operating costs, and the motors are susceptible to corrosion from lint and dust in the workshop, resulting in a high failure rate; Second, the fixed spraying mode has limited coverage, poor spray uniformity, and is prone to local over-spraying or dead zones that cannot be sprayed; Third, the nozzles are exposed for a long time and are easily clogged by lint, dust, and scale, requiring frequent manual cleaning and resulting in high maintenance costs; Fourth, they lack an adaptive protection structure, and the nozzles are easily contaminated by impurities when the machine is stopped, affecting the stability of subsequent use. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: a high-pressure spraying device for a combing workshop, comprising a water storage tank and an outlet pipe connected to the water storage tank, and a booster pump. The inlet of the booster pump is connected to the outlet pipe, and the outlet of the booster pump is connected to a main pipeline. The main pipeline is connected to multiple water-driven self-propelled base assemblies. Each water-driven self-propelled base assembly includes a pipe body connected to the main pipeline, a bearing is installed inside the pipe body, a magnetically driven impeller unit is installed on the inner ring of the bearing, and an atomizing nozzle is installed at the pipe opening. The pressure spray device also includes a self-driven spray diffusion assembly, which is used to evenly diffuse the water mist sprayed from the atomizing nozzle. The self-driven spray diffusion assembly includes a rotating sleeve rotatably disposed on the outside of the tube body. An annular synchronous magnet is disposed on the inner wall of the rotating sleeve at a position corresponding to the magnetic drive impeller unit. A conical cover is fixedly disposed on the bottom circumference of the rotating sleeve. The magnetic drive impeller unit generates a rotational driving force when water flows through it, and drives the annular synchronous magnet to rotate through magnetic field coupling, thereby driving the conical cover to rotate synchronously.

[0004] Furthermore, the magnetically driven impeller unit includes an impeller bracket fixedly connected to the inner ring of the bearing. Multiple impeller blades are arranged inside the impeller bracket, and the multiple impeller blades are connected to a ring-shaped driving magnet. The ring-shaped driving magnet is used to magnetically drive the ring-shaped synchronous magnet to rotate.

[0005] Furthermore, the self-driven spray diffusion assembly also includes multiple spiral blades fixedly disposed on the upper side of the inner wall of the conical shroud, and multiple air inlets are provided on the outer side wall of the rotating sleeve near the conical shroud.

[0006] Furthermore, an air intake protective filter is provided on the air intake port.

[0007] Furthermore, the inner wall of the rotating sleeve is also provided with flexible bristle bundles, which rotate synchronously with the rotating sleeve.

[0008] Furthermore, the high-pressure spray device also includes a variable diameter filter assembly, which includes multiple guide rails disposed on the lower side of the inner wall of the conical shroud, with a centrifugal counterweight slidably disposed on each guide rail and an anti-falling block disposed at the bottom of each guide rail; the variable diameter filter assembly also includes an elastic filter, which is connected to the multiple centrifugal counterweights.

[0009] The beneficial effects of this invention compared with the prior art are: (1) This invention utilizes water flow to impact magnetic drive impeller unit, and realizes the self-driving rotation of peripheral components through magnetic field coupling. No additional motor is required, resulting in low energy consumption, simple structure, and low failure rate; (2) The conical cover of this invention drives the spiral blades to rotate to form a spiral airflow, which disperses water mist, expands the coverage area, eliminates spray dead angles, and improves efficiency; (3) The flexible bristle bundle of this invention follows the rotation to clean the nozzle end face, the air intake protective filter filters impurities, and the variable diameter filter adaptively switches to effectively prevent clogging and reduce manual maintenance; (4) When the device of this invention is running, the filter expands without obstructing the spray, and when it stops, the filter contracts to isolate impurities, taking into account both spray effect and protective performance, and is suitable for long-term operation in the workshop.

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams only, not actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0020] like Figures 1-8 As shown, a high-pressure spraying device for a carding workshop includes a water storage tank 1 and a water outlet pipe 2 connected to the water storage tank 1, and a booster pump 3. The inlet of the booster pump 3 is connected to the water outlet pipe 2, and the outlet of the booster pump 3 is connected to a main pipeline 4. The main pipeline 4 is connected to multiple water flow self-driven base assemblies 5, the specific number of which can be set according to the specific area of ​​the textile workshop. Each water flow self-driven base assembly 5 includes a pipe body 51 connected to the main pipeline 4, a bearing 52 is provided inside the pipe body 51, a magnetic drive impeller unit 53 is provided on the inner ring of the bearing 52, and an atomizing nozzle 6 is provided at the pipe opening of the pipe body 51. The high-pressure spray device also includes a self-driven spray diffusion component 7, which is used to evenly diffuse the water mist sprayed from the atomizing nozzle 6. The self-driven spray diffusion component 7 includes a rotating sleeve 71 rotatably disposed on the outside of the tube body 51. An annular synchronous magnet 73 is disposed on the inner wall of the rotating sleeve 71 at a position corresponding to the magnetic drive impeller unit 53. A conical cover 72 is fixedly disposed on the bottom circumference of the rotating sleeve 71. The magnetic drive impeller unit 53 generates a rotational driving force when water flows through it, and drives the annular synchronous magnet 73 to rotate through magnetic field coupling, thereby driving the conical cover 72 to rotate synchronously.

[0021] like Figure 5As shown, the magnetic drive impeller unit 53 includes an impeller bracket 531 fixedly connected to the inner ring of the bearing 52. Multiple impeller blades 532 are arranged inside the impeller bracket 531. The multiple impeller blades 532 are connected to the annular drive magnet 533. The annular drive magnet 533 is used to magnetically drive the annular synchronous magnet 73 to rotate. It can achieve self-driven rotation without an additional motor. It has a simple structure, low energy consumption, and is suitable for the long-term continuous operation needs of textile workshops.

[0022] like Figure 3 , Figure 6 As shown, the self-driven spray diffusion assembly 7 also includes multiple spiral blades 76 fixedly mounted on the upper side of the inner wall of the conical shroud 72. Multiple air inlets 74 are provided on the outer side of the rotating sleeve 71 near the conical shroud 72. The rotation of the conical shroud 72 drives the spiral blades 76 to rotate, drawing air into the conical shroud 72 through the air inlets 74. This airflow disturbance disperses the high-pressure water mist, accelerating water mist diffusion and improving the uniformity and efficiency of the spray in the workshop. Alternatively, an air intake protective filter 75 can be installed on the air inlet 74 to prevent impurities such as textile lint, dust, thread ends, and lint from entering the conical shroud 72 through the air inlet 74, avoiding impurities from entangled in the spiral blades 76 and blocking the air intake channel, ensuring smooth air intake and structural stability. To prevent the atomizing nozzle 6 from being blocked by textile lint, dust, scale, and other impurities during prolonged operation, such as… Figure 7 As shown, a flexible bristle bundle 77 is also provided on the inner wall of the rotating sleeve 71, which rotates synchronously with the rotating sleeve 71. It is used to circumferentially scrape and clean the water outlet end face of the atomizing nozzle 6, remove the attached flocculents, scale and dust impurities in time, avoid the spray nozzle from being blocked, ensure uniform and stable output of high pressure spray, extend the service life of the device, and reduce the frequency of manual maintenance.

[0023] To further optimize the water mist delivery and impurity protection effects, such as Figure 3 , Figure 8 As shown, the high-pressure spray device also includes a variable diameter filter assembly 8. The variable diameter filter assembly 8 includes multiple guide rails 82 disposed on the lower side of the inner wall of the conical shroud 72. A centrifugal counterweight 83 is slidably disposed on each guide rail 82, and a fall-prevention block 84 is disposed at the bottom of each guide rail 82. The variable diameter filter assembly 8 also includes an elastic filter 81, which is connected to the multiple centrifugal counterweights 83. When the conical shroud 72 rotates, the centrifugal counterweights 83 slide outward along the guide rails 82 due to centrifugal force, thereby expanding the elastic filter 81 and enlarging the filter mesh, thus not obstructing the water mist spray. The fall-prevention block 84 serves to limit the centrifugal counterweights 83 from falling, ensuring structural reliability. When the machine stops, the centrifugal force disappears, the elastic filter 81 elastically retracts, and the mesh becomes denser, effectively isolating flying debris and dust, protecting the atomizing nozzle 6, and achieving adaptive switching between working and stopped states, balancing spray effect and protective performance.

[0024] Working principle: When this device is working, the water in the water storage tank 1 flows into the booster pump 3 through the outlet pipe 2. After being pressurized by the booster pump 3, it is delivered to the main pipeline 4 and then distributed to each water flow self-driven base assembly 5. The high-pressure water flows through the inside of the pipe body 51, impacting the magnetic drive impeller unit 53 to rotate. The magnetic drive impeller unit 53 drives the annular drive magnet 533 to rotate synchronously through the impeller bracket 531. With the help of magnetic field coupling, the annular synchronous magnet 73 on the self-driven spray diffusion assembly 7 follows the rotation, so that the rotating sleeve 71 and the conical cover 72 rotate as a whole, without the need for an additional power source, which is energy-saving and reliable.

[0025] The atomizing nozzle 6 atomizes the high-pressure water stream into a fine mist. The spiral blades 76 on the inner wall of the conical cover 72 rotate to create a spiral airflow. This airflow draws in outside air through the air inlet 74 and filters it through the air intake filter 75, forming a clean airflow barrier to prevent fly splatter from approaching the nozzle. Simultaneously, the airflow disturbance disperses the water mist, expanding the spray coverage area, eliminating spray dead zones, and improving spray uniformity and efficiency. At the same time, the flexible bristle bundles 77 inside the rotating sleeve 71 rotate with it, continuously cleaning the end face of the atomizing nozzle 6 circumferentially, promptly removing fly splatter, dust, and scale to prevent nozzle clogging and ensure stable spray output.

[0026] When the device is running, the conical cover 72 drives the variable diameter filter assembly 8 to rotate synchronously. The centrifugal force causes the centrifugal counterweight 83 to slide outward along the guide rail 82, opening up the elastic filter 81 and enlarging its mesh size so as not to obstruct the water mist spray. After the machine stops, the centrifugal force disappears, and the elastic filter 81 retracts by its own elasticity, making the mesh size denser. This effectively isolates external flying flowers and dust, protects the atomizing nozzle 6, and realizes adaptive switching between working and stopping states. It takes into account both spray performance and protective effect, and is suitable for the long-term continuous operation needs of textile workshops.
