Description

Technical Field

[0001] This utility model relates to the technical field of air showers, specifically to a device for clearing blockages in the return air network of an air shower. Background Technology

[0002] Air showers are one of the most important pieces of equipment for dealing with particulate contamination in production processes. They effectively remove dust adhering to the clothing of personnel before entering clean rooms or clean areas. The built-in nozzles can blow out strong, clean air from multiple directions. Because the air shower itself is an air filtration and circulation system, the clean, high-speed air blown out by the nozzles removes dust particles adhering to the surface of the person, which then flows away through the pre-filter at the bottom, making it difficult for dust particles floating inside the air shower to re-adhere to the person's clothing.

[0003] To avoid clogging of the return air filter, cleaning is often done by using a brush structure to clean the filter plate. However, this method has the following problems: the back-and-forth brush structure is prone to wear and tear on the filter during actual use, and the dust and impurities on the filter surface can easily cause secondary clogging during the cleaning process, resulting in a less than ideal cleaning effect.

[0004] Therefore, this utility model proposes a device for clearing blockages in the return air mesh of an air shower room. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a device for clearing blockages in the return air mesh of an air shower, which can solve the following problems:

[0006] The back-and-forth brush structure is prone to causing wear and tear on the filter screen during actual use, and the dust and impurities on the filter screen surface can easily cause secondary clogging during the cleaning process, resulting in a less than ideal cleaning effect.

[0007] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:

[0008] A device for clearing blockages in the return air screen of an air shower includes a main body. A fan mechanism and a ventilation screen are fixedly connected to the top of the main body. A door is movably connected to the front of the main body. Cleaning components are fixedly connected to both ends of the main body. Each cleaning component includes a matching outer connecting shell and an inner connecting shell. The inner connecting shell has a built-in air extraction mechanism and a return air vent on its surface. A second mounting base and a first mounting base are fixedly connected to the upper and lower ends of the inner side of the outer connecting shell, respectively. The surface of the first mounting base has a mounting groove and a dust collection chamber. A cleaning plate is embedded inside the outer connecting shell. A mounting support and a push rod are fixedly connected to the back of the cleaning plate. A cleaning strip is fixedly connected to the surface of the cleaning plate. A filter assembly is embedded between the second mounting base and the first mounting base. A spring rod is fixedly connected to the surface of the filter assembly.

[0009] Furthermore, both the outer and inner connecting shells are trapezoidal shells, positioned opposite each other, and located on the outer and inner sides of the main body, respectively. Two sets of return air inlets are provided along the upper and lower surfaces of the inner connecting shell.

[0010] Furthermore, both the first and second mounting seats are configured as longitudinal rectangular seats, with the mounting groove longitudinally opened along the outer surface of the first mounting seat. The dust collection chamber and the mounting groove are opened adjacent to each other, and the surface of the second mounting seat is also provided with a snap-fit ​​groove for the corresponding filter assembly.

[0011] Furthermore, the lateral length of the second mounting base is one-third of the lateral length of the first mounting base.

[0012] Furthermore, the push rod is set as an electric push rod, with two sets provided, and is fixedly connected to the bottom of the inner side of the outer connecting shell.

[0013] Furthermore, the cleaning plate is a rectangular plate set vertically, with a hollow interior and a small vibration mechanism installed in the center. The side of the cleaning plate that connects to the cleaning strip is made of a hard rubber layer.

[0014] Furthermore, the cleaning strip is horizontally protruding along the surface of the cleaning plate. It is made of rigid plastic and the mounting bracket is attached to the inner walls on both sides of the outer connecting shell. The mounting bracket is equipped with a longitudinal connecting shaft, and the inner walls on both sides of the outer connecting shell are provided with transverse sliding grooves corresponding to the connecting shaft.

[0015] Furthermore, the filter assembly as a whole includes a set of rectangular outer frames and a metal filter screen inside them. Two rows of spring rods are provided, which are staggered along the top and bottom of the rectangular outer frames, and the spring rods are correspondingly embedded in the mounting groove and the snap-fit ​​groove on the surface of the second mounting base.

[0016] As can be seen from the above technical solution, the beneficial effects of this utility model are:

Detailed Implementation

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] See Figure 1-4As shown, a device for clearing blockages in the return air screen of an air shower includes a main body 1. A fan mechanism 2 and a ventilation screen 3 are fixedly connected to the top of the main body 1. A door 4 is movably connected to the front of the main body 1. Cleaning components 5 are fixedly connected to both ends of the main body 1. The cleaning components 5 include an outer connecting shell 6 and an inner connecting shell 7. The inner connecting shell 7 has a built-in air extraction mechanism and a return air vent 8 on its surface. The upper and lower ends of the inner side of the outer connecting shell 6 are fixedly connected to a second mounting base 10 and a first mounting base 9, respectively. The surface of the first mounting base 9 has a mounting groove 11 and a dust collection chamber 18. A cleaning plate 12 is embedded inside the outer connecting shell 6. A mounting support 14 and a push rod 15 are fixedly connected to the back of the cleaning plate 12. A cleaning strip 13 is fixedly connected to the surface of the cleaning plate 12. A filter assembly 16 is embedded between the second mounting base 10 and the first mounting base 9. A spring rod 17 is fixedly connected to the surface of the filter assembly 16.

[0029] In this embodiment of the utility model, both the outer connecting shell 6 and the inner connecting shell 7 are trapezoidal shells, arranged opposite each other, and located on the outer and inner sides of the main body 1, respectively. Two sets of return air vents 8 are arranged along the upper and lower surfaces of the inner connecting shell 7. The first mounting seat 9 and the second mounting seat 10 are both set as longitudinal rectangular seats. The mounting groove 11 is longitudinally opened along the outer surface of the first mounting seat 9. The dust collection chamber 18 and the mounting groove 11 are adjacent to each other. The surface of the second mounting seat 10 is also provided with a corresponding snap-fit ​​groove for the filter assembly 16. The lateral length of the second mounting seat 10 is one-third of the lateral length of the first mounting seat 9. Through the first mounting seat 9 and the second mounting seat 10, in conjunction with the mounting groove 11 and the snap-fit ​​groove on the surface of the second mounting seat 10, the filter assembly 16 is fixed and limited as a whole. At the same time, the lateral lengths of the first mounting seat 9 and the second mounting seat 10 are different, which facilitates the inclined support of the filter assembly 16. The dust collection chamber 18 is used to collect dust and impurities from the surface of the filter assembly 16.

[0030] When installing the filter assembly 16, the upper and lower ends of the filter assembly 16 are respectively embedded in the snap-fit ​​groove on the surface of the second mounting base 10 and the mounting groove 11 on the surface of the first mounting base 9. Since the first mounting base 9 and the second mounting base 10 have different lateral lengths, the filter assembly 16 is installed in an inclined state, which facilitates the subsequent filtration of the airflow return air. At the same time, the inclined state of the filter assembly 16 is conducive to the subsequent dust cleaning. When cleaning the filter assembly 16, the dust and impurities on its surface are collected into the dust collection chamber 18.

[0031] The push rod 15 is an electric push rod, and two sets are provided. They are fixedly connected to the bottom of the inner side of the outer connecting shell 6. The cleaning plate 12 is a rectangular plate that is vertically set. Its interior is hollow, and a small vibration mechanism is provided in the center of the interior. The side of the cleaning plate 12 that connects to the cleaning strip 13 is made of hard rubber. The cleaning strip 13 is horizontally protruding along the surface of the cleaning plate 12 and is made of hard plastic. The mounting bracket 14 is attached to the inner walls of both sides of the outer connecting shell 6 and is provided with a longitudinal connecting shaft. The inner walls of both sides of the outer connecting shell 6 are provided with transverse sliding grooves corresponding to the connecting shaft. The push rod 15 is used to push the cleaning plate 12 to slide and adjust within the outer connecting shell 6. The cleaning plate 12 and the cleaning strip 13 on its surface are used to clean and unclog the filter holes on the surface of the filter assembly 16. The mounting bracket 14 is used to facilitate the movable connection of the cleaning plate 12 within the outer connecting shell 6.

[0032] When cleaning the filter assembly 16, the push rod 15 pushes the cleaning plate 12 to slide and adjust in the direction of the inner connecting shell 7 within the outer connecting shell 6, so that the cleaning strip 13 is embedded in the filter holes on the surface of the filter assembly 16 to unclog them. At the same time, the vibration mechanism built into the cleaning plate 12 is activated, causing the cleaning plate 12 and the cleaning strip 13 on the surface to vibrate, cleaning the dust and impurities on the surface of the filter assembly 16 through vibration. The cleaned dust and impurities fall into the dust collection chamber 18.

[0033] The filter assembly 16 includes a rectangular outer frame and a metal filter screen inside it. Two rows of spring rods 17 are provided, which are staggered along the top and bottom of the rectangular outer frame. The spring rods 17 are embedded in the mounting groove 11 and the snap-fit ​​groove on the surface of the second mounting base 10. The spring rods 17 facilitate the vibration of the filter assembly 16 under the drive of the vibration mechanism, thereby achieving the effect of filtering the airflow passing through the return air vent 8.

[0034] When the cleaning plate 12 cleans the filter assembly 16 under vibration, the spring rod 17 causes the cleaning plate 12 to vibrate simultaneously according to the vibration frequency, thereby achieving the effect of separating dust and impurities from the surface.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
