Description

Technical Field

[0001] This utility model belongs to the field of chemical processing technology, and specifically relates to a hydrogen peroxide pre-filtration device. Background Technology

[0002] Hydrogen peroxide (chemical formula H2O2) is a colorless liquid with strong oxidizing properties. It is widely used in various fields such as industry, medicine, beauty, and personal care. Hydrogen peroxide has different uses and processing methods at different concentrations. In the processing of hydrogen peroxide, a hydrogen peroxide pre-filtration device is required to pre-filter the hydrogen peroxide to remove impurities such as particulate matter, microorganisms, and organic matter, ensuring the smooth progress of subsequent processing.

[0003] Existing hydrogen peroxide pre-filtration devices work by pouring the hydrogen peroxide into the filtration unit. The hydrogen peroxide then undergoes multi-stage filtration through a combination of microporous filter elements, activated carbon filter plates, and precision filter elements. This effectively removes impurities and improves the quality and safety of the hydrogen peroxide. However, in actual use, because the filter modules are fixed and the hydrogen peroxide flows directly from top to bottom, the impact point of the hydrogen peroxide on the filter elements is fixed. The filtration volume differs between the areas near and far from the impact point, resulting in uneven filtration. Impurities accumulate at the bottom, affecting subsequent filtration. This requires manual adjustment to prevent impurities from accumulating in the same spot, causing inconvenience for processing personnel. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a hydrogen peroxide pre-filtration device. During the pre-filtration of hydrogen peroxide, the filter element can be moved horizontally to ensure that all parts of the filter element can be pre-filtered evenly, making it convenient for users.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a hydrogen peroxide pre-filtration device, including a support frame, an outer shell at the upper end of the support frame, a feed pipe at the feed inlet on the upper surface of the outer shell, symmetrically distributed guide grooves on the inner wall of the outer shell, a sliding frame slidably arranged between the guide grooves, a filter box slidably arranged inside the sliding frame, a guide port on the upper surface of the filter box and the feed pipe are connected by a telescopic hose, a discharge pipe at the discharge port on the lower surface of the filter box, and an electrical control module for driving the horizontal swaying of the filter box is also provided between the outer shell and the filter box; a microporous filter element is provided on the upper side of the inside of the filter box, an activated carbon filter plate is provided in the middle of the inside of the filter box, and a precision filter element is provided on the lower side of the inside of the filter box; buffer pads are provided at the four corners of the lower end of the support frame.

[0006] As a further improvement of this utility model, the electronic control module includes a rotating shaft symmetrically arranged on the inner wall of the outer shell. A drive rod is fixedly sleeved on the outer arc surface of the rotating shaft, and a drive groove is opened in the middle of each drive rod. A sliding rod is symmetrically distributed on the middle of the outer side of the sliding frame via a support column. The sliding rods are slidably connected to adjacent drive grooves. An electronic control unit for driving the drive rods to rotate is also provided on the outer shell. A driven unit for driving the filter box to sway back and forth is also provided between the filter box and the outer shell. The driven unit includes a first fixed plate evenly arranged on the front inner wall of the outer shell, and a second fixed plate evenly distributed on the rear inner wall of the outer shell. A guide groove is opened on the rear side of the first fixed plate, and a guide protrusion is provided on the front side of the second fixed plate. The guide grooves are respectively fitted with adjacent guide protrusions laterally. Rollers are evenly distributed on both the front and rear sides of the filter box, and the guide protrusions and guide grooves are respectively fitted with adjacent rollers.

[0007] As a further improvement of this utility model, the motor control unit includes motors symmetrically arranged on the outside of the housing, and the output shaft of the motor is fixed to the adjacent rotating shaft by a coupling.

[0008] As a further improvement of this utility model, a control board is provided on the front side of the outer shell, and all motors are electrically connected to the control board.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the motors on both sides are controlled to run synchronously by the control panel. The drive rod drives the sliding frame to slide between the guide slide groove through the sliding relationship between the sliding rod and the drive groove, so that the sliding frame drives the filter box to swing back and forth.

[0011] Secondly, during the back-and-forth swaying of the filter box, the rollers on its front and rear sides move with the adjacent guide protrusions or guide grooves, causing the filter box to sway back and forth.

[0012] Thirdly, during the pre-filtration of hydrogen peroxide, the microporous filter element, activated carbon filter plate, and precision filter element are shaken horizontally, so that each part of the filter element can be evenly pre-filtered with hydrogen peroxide, making it convenient for personnel to use.

[0013] Fourth, the buffer pads at the bottom of the bracket can effectively increase the friction between the bracket and the ground, which can effectively prevent the outer casing from easily moving under the action of external forces during actual use. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 4As shown, the system includes a support 101, an outer shell 103 at the upper end of the support 101, a feed pipe 104 at the feed inlet on the upper surface of the outer shell 103, symmetrically distributed guide grooves 105 on the inner wall of the outer shell 103, a sliding frame 106 slidably disposed between the guide grooves 105, a filter box 108 slidably disposed inside the sliding frame 106, a guide port on the upper surface of the filter box 108 and the feed pipe 104 connected by a telescopic hose 107, a discharge pipe 109 at the discharge port on the lower surface of the filter box 108, and an electrical control module for driving the filter box 108 to swing horizontally between the outer shell 103 and the filter box 108.

[0022] like Figure 3 , 4 As shown, a microporous filter element 110 is provided on the upper side of the inside of the filter box 108, an activated carbon filter plate 111 is provided in the middle of the inside of the filter box 108, and a precision filter element 112 is provided on the lower side of the inside of the filter box 108.

[0023] like Figure 2 , 3 As shown, the electronic control module includes a rotating shaft 201 symmetrically rotatably mounted on the inner wall of the housing 103. Drive rods 202 are fixedly sleeved on the outer arc surface of the rotating shaft 201. Drive grooves 203 are formed in the middle of each drive rod 202. Symmetrically distributed sliding rods 204 are mounted on the middle of the outer side of the sliding frame 106 via support columns. The sliding rods 204 are slidably connected to adjacent drive grooves 203. An electronic control unit for driving the drive rods 202 to rotate is also provided on the housing 103. A driven unit for driving the filter box 108 to sway back and forth is also provided between the filter box 108 and the housing 103. The driven unit includes components evenly distributed... The inner wall of the outer casing 103 has a fixing plate 205 on the front side, and a fixing plate 208 is provided on the inner wall of the rear side of the outer casing 103. The rear side of the fixing plate 205 is provided with a guide groove, and the front side of the fixing plate 208 is provided with a guide protrusion. The guide groove is installed in conjunction with the laterally adjacent guide protrusion. The front and rear sides of the filter box 108 are provided with rollers 206 that are evenly distributed. The guide protrusion and the guide groove are installed in conjunction with the adjacent rollers 206. The motor control unit includes a motor 207 symmetrically arranged on the outer side of the outer casing 103. The output shaft of the motor 207 is fixed to the adjacent rotating shaft 201 by a coupling.

[0024] like Figure 1 As shown, a control board 301 is provided on the front side of the housing 103, and the motors 207 are all electrically connected to the control board 301.

[0025] When hydrogen peroxide pre-filtration is required, the external delivery pipe is connected to the feed pipe 104. The control board 301 controls the synchronous operation of the motors 207 on both sides, causing the output shafts of the motors 207 to drive the connected rotating shafts 201 to rotate. The rotation of the rotating shafts 201 drives the drive rods 202 on both sides to rotate synchronously and in the same direction. During the swinging of the drive rods 202, the sliding rod 204 moves inside the drive groove 203, causing the drive rod 202 to drive the sliding frame 106 to slide between the guide grooves 105 through the sliding relationship between the sliding rod 204 and the drive groove 203. This causes the sliding frame 106 to drive the filter box 108 to swing back and forth. During the back-and-forth swinging of the filter box 108, the filter box 108 drives the rollers 20 on its front and rear sides. 6 moves between adjacent guide protrusions or guide grooves, thereby causing the filter box 108 to sway back and forth and left and right during the back-and-forth swaying process through the cooperation between the guide protrusions and guide grooves; hydrogen peroxide enters the filter box 108 through the cooperation of the feed pipe 104 and the telescopic hose 107. The hydrogen peroxide is filtered step by step through the microporous filter element 110, activated carbon filter plate 111 and precision filter element 112 arranged from top to bottom inside the filter box 108, which can effectively eliminate large molecular impurities, color and odor in hydrogen peroxide. During the pre-filtration of hydrogen peroxide, the microporous filter element 110, activated carbon filter plate 111 and precision filter element 112 are driven to sway horizontally, so that each position on the filter element can be evenly pre-filtered with hydrogen peroxide, which is convenient for personnel to use.

[0026] According to another embodiment of the present invention, such as Figure 1 , 4 As shown, buffer pads 102 are provided at the four corners of the lower end of the bracket 101. During use, the buffer pads 102 at the lower end of the bracket 101 can effectively increase the friction between the bracket 101 and the ground, which can effectively prevent the outer shell 103 from easily moving under the action of external force during actual use.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
