These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0029] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0030] In the prior art, the production process of zinc oxide resistors typically uses a V-shaped moisture extractor to moisten the granulated powder. A motor drives a drive shaft, continuously rotating the V-shaped silo, causing the powder inside to flip upside down. Atomizing nozzles within the silo continuously spray water, evenly moistening the powder and achieving moisture retention. However, the atomizing nozzles in the V-shaped moisture extractor control the spray volume solely through time, and the atomization range is fixed. Therefore, as the powder amount changes, the V-shaped moisture extractor may experience incomplete atomization coverage and uneven moisture content.

[0031] In response to the above technical problems, the inventors realized that a single atomizing nozzle that cannot control the spray volume cannot ensure uniform moisture content of the powder. Based on this, the inventors, after in-depth analysis and research on the above technical problems, considered designing a water-containing device with multiple atomizing nozzles and controllable spray volume. By precisely controlling the water spray volume on the atomizing nozzles, the atomizing range of the atomizing nozzles can be adjusted, thereby ensuring full coverage of the atomization range and more uniform moisture content of the powder, thereby solving the technical problems of existing V-shaped water-containing devices such as incomplete atomization range coverage and uneven moisture content of the powder.

[0032] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0033] Figure 1 This is a schematic diagram of the structure of the water-containing device for powder production provided in the embodiment of the present application. Figure 1 As shown, the water-containing device 100 for powder production includes:

[0034] A support member 101, a tank body 102 disposed transversely on the support member 101, and a spray member 103, wherein:

[0035] The spray element 103 includes a water storage portion 104. A water inlet is provided at a first end of the water storage portion 104. A plurality of atomizing nozzles 105 are provided at intervals at a second end of the water storage portion 104. The first end of the water storage portion 104 is provided outside the tank body 102, and the second end of the water storage portion 104 is provided inside the tank body 102.

[0036] A flow meter 106 is provided at the water inlet of the water storage portion 104 .

[0037] The support member 101 refers to the basic structure used to support the entire device, which is usually a stable frame or base that can bear the weight of the tank 102 and other components and maintain the stability of the device.

[0038] The tank body 102 is a main structure for containing powder materials and is used for mixing powder materials.

[0039] The atomizing nozzle 105 refers to a device that sprays the liquid in the water storage part 104 onto the material inside the tank body 102 in the form of fine particles, wherein each atomizing nozzle 105 is evenly distributed at the water outlet of the water storage part 104, which can ensure that the liquid is evenly sprayed in the tank body 102.

[0040] The flow meter 106 is mainly used to monitor the amount of liquid entering the water storage portion 104, thereby ensuring the uniformity and controllability of liquid spraying.

[0041] Specifically, the tank body 102 is placed horizontally on the support 101 and adopts a drum design, which can evenly mix the powder in the tank body 102 during rotation; the water storage part 104 is designed to be long and cylindrical, and its first end is connected to an external water source or liquid storage tank through a pipe, and is provided with a water inlet, and a high-precision flow meter 106 is installed on the water inlet for real-time monitoring and adjustment of the amount of liquid entering the water storage part 104 to ensure the uniformity and accuracy of the spray; the second end of the water storage part 104 is located inside the tank body 102, and a plurality of atomizing nozzles 105 are arranged at intervals along its length. These nozzles can evenly atomize the liquid and spray it on the powder inside the tank body 102 to ensure that the moisture content of the powder is uniform; in addition, the arrangement and number of the nozzles can be adjusted according to the length of the tank body 102 and the processing requirements of the powder to ensure that the atomized liquid can cover the entire powder area.

[0042] Figure 2 This is another structural diagram of the water-containing device for powder production provided in the embodiment of the present application. Figure 2 As shown, each atomizing nozzle 105 is further provided with a sensor 107 for detecting the amount of powder covering the atomizing nozzle 105 .

[0043] Among them, a sensor 107 is set near each atomizing nozzle 105 to detect whether the nozzle is covered or blocked by powder. In one feasible method, the sensor 107 can be an infrared sensor, which monitors the working status of the nozzle by emitting and receiving infrared rays. If it is detected that the nozzle is covered by powder or blocked, the infrared sensor will send a signal to prompt that the nozzle needs to be cleaned or adjusted.

[0044] Specifically, the design of the sensor 107 ensures that the atomizing nozzle 105 remains unobstructed during operation, avoiding uneven spraying or nozzle blockage caused by powder covering the nozzle. For example, the infrared sensor can be connected to the central control system to achieve automated management and real-time monitoring, greatly improving the reliability and work efficiency of the device.

[0045] Optionally, the device further comprises:

[0046] An alarm is connected to the sensors 107 on each atomizing nozzle 105 so as to sound an alarm when the powder coverage amount collected by any sensor 107 exceeds a preset powder coverage amount.

[0047] Among them, in one feasible method, the sensor 107 of each atomizing nozzle 105 is connected to a central alarm system. For example, when the sensor 107 detects that the powder coverage exceeds a preset value, the alarm system will issue an audible and visual alarm to remind the operator to intervene, thereby improving the degree of automation of the device and greatly reducing the workload of manual monitoring.

[0048] At the same time, the alarm system can also be connected to the remote control system, allowing equipment managers to monitor the working status of the equipment in real time through mobile phones or computers, and take timely measures when problems arise, ensuring the stable operation of the device in various environments.

[0049] In another possible implementation, when the alarm sounds, the operator should immediately stop the operation of the device. Specifically, to ensure safety, the power supply of the device should be disconnected and the power switch should be locked to prevent the device from accidentally starting during the cleaning process. Then, after confirming that the device has completely stopped operating, the operator should open the observation port or inspection port of the device and carefully check the position of all atomizing nozzles 105. Through visual inspection or manual testing, the specific nozzle covered or blocked by powder can be determined. For minor blockages, compressed air can be used to blow back from the nozzle of the nozzle to blow out the accumulated powder. For more serious blockages, the nozzle can be removed for thorough cleaning or replacement. In addition, it should be noted that if manual cleaning cannot completely remove the blockage, the operator can soak and rinse the nozzle with an appropriate cleaning fluid. After soaking the nozzle in the cleaning fluid for a period of time, the nozzle can be cleaned again with compressed air or manual tools to ensure that the blockage inside the nozzle is completely removed. After cleaning, the nozzle should be reinstalled and necessary debugging should be carried out. Turn on the power of the device, run the nozzle test program, observe the spray effect and spray angle of the nozzle, and ensure that the nozzle works normally after cleaning and the atomization effect is good

[0050] Optionally, the tank body 102 is a cylindrical drum or a prismatic drum.

[0051] Among them, in one feasible method, the tank body 102 is designed as a cylindrical drum structure, which can generate uniform centrifugal force when rotating, so that the powder inside the tank body 102 can be evenly distributed and fully mixed. In addition, the cylindrical design has no protruding parts when the drum rotates, which can effectively avoid the accumulation or blockage of powder, and the regular shape of the tank body 102 is safer during operation.

[0052] In another feasible embodiment, the tank body 102 can be designed as a cylindrical drum design, and the interior of the tank body 102 can be designed as multiple facets, each facet being equipped with a spiral blade 109. The prismatic structure can enhance the turning effect of the powder, which is beneficial for the powder to fully contact the atomizing nozzle 105 during the rotation process, thereby further improving the uniformity of the water content.

[0053] Optionally, a driving member 108 is further provided on the support member 101 , and the driving member 108 is connected to the side of the tank body 102 for driving the tank body 102 to rotate.

[0054] A driving member 108, such as an electric motor or a hydraulic motor, is installed on the support member 101 to connect the transmission device to the side of the tank body 102. The driving member 108 can control the tank body 102 to rotate at an appropriate speed so that the powder inside the tank body 102 is continuously turned and mixed.

[0055] In one feasible manner, the rotation speed of the tank body 102 can be adjusted according to the type of powder to be processed and the water content requirement, ensuring that the powder is evenly contacted with the atomized liquid during the mixing process to achieve a good water content effect. In addition, a speed sensor and a regulator can also be configured in the driving member 108 to accurately control the rotation speed of the tank body 102 to avoid affecting the powder processing effect due to too high or too low speed.

[0056] Optionally, a plurality of spiral blades 109 are provided on the inner wall of the tank body 102 .

[0057] Among them, according to the size of the tank body 102 and the characteristics of the powder, a plurality of spiral blades 109 can be evenly welded on the inner wall of the tank body 102, which can effectively enhance the mixing effect of the powder and improve the uniformity of the spray water content. Specifically, the spiral angle and spacing of the spiral blades 109 can be determined according to the actual application, so that the powder can be turned left and right under the guidance of the blades during the rotation of the tank body 102, thereby ensuring that the powder can maintain a uniform flow inside the tank body 102, avoiding the powder from concentrating in a certain part of the tank body 102 or falling from a high place to destroy the morphology of the powder; In addition, the spiral blades 109 are relatively dense, so that all the powder is exposed to the atomizing nozzle, avoiding uneven water content, and the powder continues to turn back and forth at the bottom of the silo, which will not cause the powder to contact the atomizing nozzle, avoiding the phenomenon of clogging the atomizing head and losing control of the water content.

[0058] Optionally, the tank body 102 is provided with a loading port 110 .

[0059] A loading port 110 is also provided at the top of the tank 102 for feeding powder. The design of the loading port 110 facilitates feeding. In one embodiment, the loading port 110 can be equipped with a sealing cover to prevent the external environment from affecting the interior of the tank 102 and to prevent leakage of powder during the loading process. Furthermore, the position and size of the loading port 110 are designed based on the structure of the tank 102 and the needs of powder handling, ensuring that the powder can smoothly enter the tank 102 and fully contact and mix with the rotating spiral blades 109 and the atomizing nozzle 105.

[0060] Optionally, the device further comprises:

[0061] A vacuum suction piece is connected to the feeding port 110 .

[0062] In the embodiment of the present application, a vacuum suction component is further provided on the loading port 110 and is connected to the loading port 110 through a pipe. Specifically, the vacuum suction component can generate negative pressure and suck the powder into the tank body 102 through the pipe, thereby greatly reducing the need for manual handling and avoiding secondary contamination of the powder.

[0063] In addition, in a feasible way, the vacuum suction device can also be connected to the central control system. By setting the suction speed and time, the amount of material loaded each time can be ensured to be accurately controlled. The vacuum suction method also reduces the dispersion of dust and improves the cleanliness and safety of the working environment.

[0064] Optionally, a feeding port 111 is further provided on the side of the tank body 102 .

[0065] Among them, a discharge port 111 is also provided on the side of the tank body 102 to facilitate the discharge of the powder from the inside of the tank body 102 after processing. Specifically, the position of the discharge port 111 is designed to be at the bottom or side of the tank body 102, and can cooperate with the rotation direction of the tank body 102 to discharge the powder by gravity or the guidance of blades.

[0066] In addition, in one feasible method, when unloading is required, the driving member 108 can control the tank body 102 to reverse, so that the spiral blade 109 rotates in the opposite direction, pushing the powder to the unloading port 111, realizing automated unloading operation, thereby ensuring uniform discharge of the powder and avoiding blockage problems caused by powder retention.

[0067] Optionally, the outer wall of the tank body 102 is further covered with a protective layer 112 .

[0068] Among them, a protective layer 112 is coated on the outer wall of the tank body 102. The protective layer 112 can be made of wear-resistant and corrosion-resistant materials, such as polyethylene or rubber. Specifically, the protective layer 112 can reduce the impact force of the tank body 102 during rotation, and protect the tank body 102 from corrosion and wear in the external environment; in addition, the protective layer 112 can also play a certain heat-insulating role, preventing the temperature inside the tank body 102 from affecting the external environment or the safety of the operator, thereby extending the service life of the device and improving the safety and stability of the entire system.

[0069] Furthermore, in one practicable embodiment, the device is designed to fully consider automatic cleaning after powder processing, thereby improving maintenance efficiency and service life of the device. For example, during the cleaning process, the operator only needs to add an appropriate amount of clean water or zirconium oxide beads to the interior of the tank 102 and then start the device to rotate the tank 102 at a moderate speed.

[0070] Specifically, during the rotation process, the zirconium oxide beads will roll along the spiral blades 109 and the surface of the tank wall inside the tank body 102. Due to their high hardness and appropriate weight, they can effectively remove the powder residue on the tank wall and the spiral blades 109. This method mainly uses the principle of physical friction for cleaning, which not only avoids the corrosion problems that may be caused by the use of chemical cleaning agents, but also can thoroughly clean the residue inside the tank body 102. In addition, the cleaning operation usually only takes a few minutes. The specific time can be adjusted according to the adhesion degree of the residue and the cleaning requirements of the tank body 102. When the cleaning is completed, the cleaning liquid and residue can be discharged through the discharge port 111, or guided to the waste liquid treatment device through a specially designed drainage system, thereby simplifying the cleaning process of the equipment, reducing the need for manual intervention, and improving the efficiency of the equipment. At the same time, regular automatic cleaning also ensures that the inside of the tank body 102 is always kept clean, avoids cross-contamination between different batches of materials, and helps to maintain production consistency and product quality stability.
