Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a stirring and filtering device that can prevent filter screen clogging. Background Technology

[0002] Skin surface rehabilitation spray is a product used for skin care and repair. It is usually in the form of a spray and can be sprayed evenly on the skin problem area. It is convenient and quick. The production process requires mixing a variety of raw materials, which may contain some impurities and larger particles. These need to be filtered through a filtration device to prevent nozzle clogging and ensure smooth spraying. The stirring and filtering device has both stirring and filtering functions. Stirring can also prevent the filter cake from becoming too dense and causing the filter screen to become clogged.

[0003] Current mixing and filtration devices typically prevent filter clogging through mixing. However, a single-layer filter has a limited capacity to trap contaminants. When impurities accumulate to a certain amount, the filter may still become clogged, potentially shortening the filtration cycle. Furthermore, filters often need to be replaced periodically, which usually requires opening the device, potentially contaminating the internal components. To ensure the quality of spray production, the entire device often needs to be cleaned before it can be used again, which may affect the spray production efficiency.

[0004] Therefore, those skilled in the art have provided a stirring and filtering device that can prevent filter screen clogging, in order to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stirring filter device that can prevent filter screen clogging. This stirring filter device ensures both the smoothness and efficiency of the filtration process and the ease of cleaning the filter screen.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A stirring and filtering device that can prevent filter screen clogging includes a support mechanism and a main body mechanism, wherein a stirring mechanism is provided inside the main body mechanism.

[0008] The support mechanism includes a support frame and a fixing ring, and a control motor is fixedly installed on one side of the support frame;

[0009] The stirring mechanism includes a rotary motor, and a stirring rod is fixedly installed at the output end of the rotary motor. Multiple blades and multiple sealing rings are fixedly installed on the outer surface of the stirring rod.

[0010] The main structure includes a main tank, a lower port is provided at the lower end of the main tank, an air pump is fixedly provided at the rear end of the main tank, multiple sewage outlets are fixedly provided at the front end of the main tank, and multiple filter screens are fixedly fitted on the inner surface of the main tank, with a sealing ring fixedly fitted at the middle position of each of the multiple filter screens.

[0011] Furthermore, the two sides of the fixing ring are respectively rotatably sleeved on the two sides of the support frame, and one side of the fixing ring is fixedly connected to the output end of the control motor.

[0012] Furthermore, the rotating motor is fixedly mounted on the upper end of the main body tank, and the output end of the rotating motor is rotatably sleeved on the upper end of the main body tank.

[0013] Furthermore, the multiple blades are grouped into sets of three, and the multiple blades are located at three different heights.

[0014] Furthermore, the plurality of sealing rings are located at three different heights, and the plurality of sealing rings and the plurality of blades are staggered along the vertical direction.

[0015] Furthermore, the stirring rod is rotatably fitted within three sealing rings, and the plurality of sealing rings are rotatably fitted within the three sealing rings respectively.

[0016] Furthermore, a sealing plug is fitted onto the upper end of the main body tank, and the outer surface of the main body tank is fixedly fitted into the middle of the fixing ring near the lower end.

The stirring and filtering device is equipped with a support mechanism and a main body mechanism, including a control motor and a fixing ring. The fixing ring is fixedly sleeved on the outer surface of the main body tank. The control motor can drive the fixing ring to rotate, thereby driving the main body tank to rotate. When the main body tank is upright, it is used for liquid filtration. When the main body tank is tilted and upside down, it is used for cleaning the filter screen. This can avoid the trouble of disassembling the filter screen and also avoid cleaning the inside of the device, thus ensuring the production efficiency of spraying.

[0019] 2. This utility model proposes a stirring and filtering device that can prevent filter screen clogging. The stirring and filtering device is equipped with a stirring mechanism and a main body mechanism. It is equipped with multiple layers of filter screens, and each layer of filter screen is equipped with stirring blades. The multiple layers of filter screens play a filtering role. The filter holes of the multiple layers of filter screens decrease in size from top to bottom. The layered interception mechanism can effectively avoid the concentrated accumulation of particulate matter, which would cause the single layer of filter screen to clog quickly. The stirring blades can prevent the filter residue from forming a dense filter cake, extend the filtration cycle, and thus ensure the production efficiency of spraying. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 An embodiment of this utility model is provided: a stirring and filtering device that can prevent filter screen clogging, including a support mechanism 1 and a main body mechanism 3, wherein a stirring mechanism 2 is provided inside the main body mechanism 3;

[0028] Specifically, the support mechanism 1 can both support the filter tank and drive the tank to rotate. The stirring mechanism 2 can stir the liquid inside, which on the one hand fully mixes the various components in the liquid, and on the other hand prevents filter residue from accumulating on the filter screen and causing the filter screen to become clogged. The main body mechanism 3 is the main place for liquid filtration.

[0029] Reference Figure 2 , Figure 3 The support mechanism 1 includes a support frame 101 and a fixing ring 103. A control motor 102 is fixedly installed on one side of the support frame 101.

[0030] The two sides of the fixing ring 103 are respectively rotatably sleeved on the two sides of the support frame 101, and one side of the fixing ring 103 is fixedly connected to the output end of the control motor 102.

[0031] Specifically, the support frame 101 consists of a bottom plate at the lower end and frames on both sides. It is made of a material with high density and high hardness. The bottom plate connects the two frames to ensure the stability of the support frame 101. The control motor 102 can drive the rotating of the fixing ring 103. The two sides of the fixing ring 103 are respectively fitted on the two frames near the upper end. The fixing ring 103 is fitted on the outer surface of the main body tank 301. The fixing ring 103 not only supports the main body tank 301, but also drives the main body tank 301 to rotate.

[0032] Reference Figure 3 , Figure 4 The stirring mechanism 2 includes a rotary motor 201, and a stirring rod 202 is fixedly installed at the output end of the rotary motor 201. Multiple blades 204 and multiple sealing rings 203 are fixedly installed on the outer surface of the stirring rod 202.

[0033] The rotating motor 201 is fixedly installed at the upper end of the main body tank 301. The output end of the rotating motor 201 is rotatably sleeved at the upper end of the main body tank 301. Multiple blades 204 are divided into groups of three, and the multiple blades 204 are located at three different heights. Multiple sealing rings 203 are located at three different heights. The multiple sealing rings 203 and multiple blades 204 are staggered along the vertical direction. The stirring rod 202 is rotatably sleeved in three sealing rings 307, and the multiple sealing rings 203 are rotatably sleeved in three sealing rings 307 respectively.

[0034] Specifically, the rotating motor 201 is the power structure in the stirring mechanism 2. The stirring rod 202 is a vertically placed rod-shaped structure. The stirring rod 202 is sleeved between the three filter screens 306. The three sealing rings 203 are located at three different heights and are respectively rotatably sleeved in the sealing rings 307. During the rotation of the stirring rod 202, the sealing performance between the stirring rod 202 and the sealing rings 307 is ensured, separating the liquid in the upper and lower layers of the filter screen 306. The multiple blades 204 are divided into three groups of three, each group of three, located at different heights. Each group of blades 204 is located in the space at the upper end of the three filter screens 306.

[0035] Reference Figure 2-4 The main body 3 includes a main tank 301. The lower end of the main tank 301 is provided with a lower port 303. A vacuum pump 304 is fixedly installed at the rear end of the main tank 301. Multiple sewage outlets 305 are fixedly installed at the front end of the main tank 301. Multiple filter screens 306 are fixedly sleeved on the inner surface of the main tank 301. A sealing ring 307 is fixedly sleeved in the middle of each of the multiple filter screens 306.

[0036] A sealing plug 302 is fitted onto the upper end of the main body tank 301, and the outer surface of the main body tank 301 is fixedly fitted onto the middle of the fixing ring 103 near the lower end;

[0037] Specifically, the main tank 301 is the primary site for liquid filtration. Its upper part is cylindrical, and its lower part is an inverted cone. The sealing plug 302 can be removed, allowing the liquid to be filtered to be poured into the main tank 301 through its holes. The lower port 303 is the outlet for the filtered liquid and also the inlet for the cleaning liquid. The air pump 304 extracts gas from the tank, accelerating the filtration process through pressure difference. The wastewater outlet 305 is the outlet for wastewater containing impurities after cleaning the filter screens. Three filter screens 306 are located at three different heights, dividing the interior of the main tank 301 into three spaces. The filter holes in the three filter screens 306 are of different sizes, gradually decreasing in size from top to bottom. The three filter screens 306 can filter the liquid layer by layer, effectively preventing filter clogging. The sealing ring 307 cooperates with the sealing ring 203 to ensure the sealing performance between the stirring rod 202 and the sealing ring 307. Both the lower port 303 and the wastewater outlet 305 are controlled by valves.

[0038] Working principle: When using this device for filtration, open the sealing plug 302 and pour the liquid to be filtered into the main tank 301. Start the rotating motor 201, and the blades 204 and stirring rod 202 will rotate accordingly. After passing through the first filter screen 306, larger impurities can be filtered out. Then, the liquid passes through the lower filter screen 306 in sequence until it reaches the lower port 303. Open the valve of the lower port 303, and the filtered liquid flows out of the main tank 301. Start the air pump 304 to extract the gas from the main tank 301. A certain pressure difference is generated between the upper and lower ends of the filter screen 306, which can accelerate the filtration process.

[0039] When cleaning the filter screen 306, re-fix the sealing plug 302 to the upper end of the main body tank 301, start the rotating motor 201, drive the fixing ring 103 and the main body tank 301 to rotate, so that the main body tank 301 is tilted, with the upper end of the main body tank 301 facing down, the lower port 303 facing up, and the sewage outlet 305 located at the lower end. Pour cleaning water into the main body tank 301 from the lower port 303. The reverse impact of the water flow can remove the filter residue from the filter screen 306 and then discharge it from the sewage outlet 305.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
