Description

Technical Field

[0001] The invention belongs to the technical field of dust-free workshops, and in particular relates to a high-efficiency dust removal system for a dust-free workshop and a use method thereof. Background Art

[0002] A dust-free workshop, also known as a clean room or dust-free room, is a specialized standard workshop for the production of precision products or pollution-sensitive parts. The dust-free workshop has extremely high requirements for the control of indoor pollution. It has strict control over pollutants such as dust and bacteria in the air, as well as room temperature, cleanliness, indoor pressure, air flow speed, etc. With the development of science and technology and the upgrading of my country's industries, the application of dust-free workshops is becoming more and more extensive, especially in the production fields of electronics and communications.

[0003] To some extent, talents are the biggest source of pollutants in dust-free workshops. Pollutant particles on people's clothes, hair, and shoes are one of the biggest sources of pollution in dust-free workshops. Therefore, before entering the dust-free workshop, workers need to change into special shoes (dust-free shoes, anti-static shoes, etc.), go through air showers, and put on work clothes before entering the dust-free workshop. Generally, ordinary shoes worn by workers are cleaned before entering the air shower room and changed into special shoes for dust-free workshops before entering the air shower room. However, we found that after coming out of the air shower room, there is still a high possibility that there is a certain amount of dust on the soles and uppers of the special shoes for dust-free workshops. The pattern analysis room of the soles is also a place where dust, fiber, etc. are easily accumulated. Moreover, after entering the dust-free workshop, due to the friction between the soles and the ground when walking at work and the continuous generation of debris by the human body, the uppers of the special shoes for dust-free workshops, especially the soles, will be contaminated with dust and other pollutant particles again.

[0004] The invention patent with the patent number of 2017110457657 and the name of "A shoe cleaning device for a dust-free workshop" discloses a shoe cleaning device for a dust-free workshop, including a front brush device, a side brush device, a dust suction device, a bottom scraping device, a drying device and a bottom plate. The relevant personnel only need to place their feet on the bottom scraping device, the bottom scraping device cleans the sole, the front brush device and the side brush device will automatically feed and clean the upper, the dust on the surface of the shoe will be sucked away by the dust suction device after cleaning, and then move to the drying device to dry the sole. This device is mainly aimed at the environmental requirements of dust-free workshops, and can automatically clean various parts of the shoes at the same workstation, and then remove the moisture from the bottom of the shoes through the drying device. The disadvantage of this device is that when workers clean their shoes, they need to stop near the shoe cleaning device for a period of time to wait for the device to complete the cleaning, which will cause workers to queue up during rush hour, with low efficiency and small processing volume per unit time.

[0005] In view of this, it is necessary to provide a device that can continuously and massively remove dust from shoes. Summary of the invention

Detailed implementation manners

[0030] The present invention will be further described in detail below through embodiments, so that those skilled in the art can implement it with reference to the text of the specification.

[0031] It should be understood that the terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0032] Embodiment 1

[0033] As Figures 1-3 shown, an efficient dust removal system for a dust-free workshop includes a dust removal walkway and a vacuum pumping device with a controller. The dust removal walkway includes a walkway groove 1 and a baffle 2 horizontally installed in the middle of the walkway groove. A number of hollow horizontal strip holes 3 are evenly processed on the baffle; the rear end of the walkway groove is the inlet 11, and the front end is the outlet 12;

[0034] An electric rolling brush 4 is provided along the length direction in the walking path groove, and the electric rolling brush is arranged below the baffle; the electric rolling brush includes a rotating shaft 41, and a plurality of brush disks 42 are vertically arranged on the rotating shaft perpendicular to the axis. The edges of the brush disks are evenly provided with first bristles 43 in a radial shape. The brush disks correspond to the horizontal strip holes one by one, and the first bristles on the upper part of the brush disks extend out from the horizontal strip holes;

[0035] On both sides of the upper part of the walking path groove, a plurality of pairs of elastic dust removal rods 5 are provided. The elastic dust removal rods include a dust suction pipe 51 and a buffer sleeve 52 sleeved outside the dust suction pipe. The buffer sleeve can provide a carrier for the second bristles and can buffer the impact on the shoes when the elastic dust removal rods rebound, reducing the discomfort of the human body; a plurality of air holes 53 are axially processed on the lower side wall of the dust suction pipe; through holes corresponding to the air holes of the dust suction pipe are processed on the lower side wall of the buffer sleeve; downward second bristles 54 are provided on both sides of the through holes; the first bristles and the second bristles are arranged in a staggered manner to reduce interference with each other; a vacuum pumping device is connected to the dust suction pipes of the elastic dust removal rods one by one through hoses; the dust suction pipe is fixed on the inner wall of the walking path groove through an elastic rod 511; each pair of oppositely arranged elastic dust removal rods forms a shoe upper dust removal group.

[0036] On both sides below the baffle, porous vacuum dust suction pipes 6 are provided, or the baffle is provided with dust suction holes (such as provided on the two side walls of the horizontal strip holes). Specifically, the vacuum dust suction pipes or the dust suction holes of the baffle can be arranged in sections and are linked with switches or electric control valves on the dust suction pipes (such as being connected in series with the dust suction pipes through hoses, etc.). Wherever the worker walks, the vacuum dust suction pipes or the dust suction holes of the baffle at that place are opened for dust suction, which is more energy-saving.

[0037] A push-button switch 55 with a spring is provided on the dust suction pipe; the push-button switch has a protruding button 56, and the button can be automatically reset under the action of the spring; the button is arranged on the side of the dust suction pipe near the outlet of the walking path groove, and a limiting plate 57 fixed on the inner wall of the walking path groove is provided in front of the button. The button abuts against the limiting plate. When the elastic dust removal rod moves forward, the button is blocked by the limiting plate and the switch is turned on. Specifically, the limiting plate can be arranged perpendicular to the inner wall of the walking path groove; or the limiting plate can be obliquely arranged facing the rotation direction of the elastic dust removal rod, and the end face of the button is designed as an inclined surface adapted to the limiting plate so that the switch is more easily triggered to be turned on. In this embodiment, the limiting plate is arranged perpendicular to the side surface of the inner wall of the walking path groove.

[0038] The elastic dust removal rod is a straight rod or a bent rod with a curve adapted to the instep of the human body. In this embodiment, the elastic dust removal rod is a horizontally arranged straight rod.

[0039] The distance between the elastic dust removal rod and the baffle is not less than 3 cm. If the distance between the elastic dust removal rod and the baffle is too small, it is not conducive to the front end of the shoes to enter between the elastic dust removal rod and the baffle, nor is it conducive to the unfolding of the second bristles. Of course, the distance between the elastic dust removal rod and the baffle cannot be too large, and it is preferably 3 - 6 cm.

[0040] There are two dust removal walkways arranged in parallel, and the interval between the two dust removal walkways does not exceed 30 cm. The interval between the two dust removal walkways is preferably in line with the horizontal distance between the two feet when a person walks normally.

[0041] An infrared sensor 7 is provided at the entrance of the dust removal walkway.

[0042] Embodiment 2

[0043] As Figures 4-5 shown, similar to Embodiment 1, the difference is that an electric control valve 58 is provided on the dust suction pipe. The two elastic dust removal rods in the shoe upper dust removal group are in the same straight line, and an induction device 59 is provided between the adjacent ends of the two elastic dust removal rods. The electric control valve is electrically connected to the induction device; when a worker passes through the dust removal walkway, the two elastic dust removal rods in the shoe upper dust removal group are separated, and the induction device is triggered to open the electric control valve. The induction device can adopt photoelectric induction type, pressure sensitive type, Hall type and other sensors.

[0044] The induction device includes a first sensor 591 and a second sensor 592 arranged front and back; when any one of the first sensor and the second sensor is triggered, or when the first sensor and the second sensor are triggered in sequence, the electric control valve is opened; for example, when a worker passes through the dust removal walkway, the two elastic dust removal rods in the shoe upper dust removal group move forward (rotate) and are separated. The second sensor on the front side first senses the movement of the elastic dust removal rod and is triggered, and the first sensor senses later; when the second sensor and the first sensor are not triggered in sequence, an alarm is issued to prompt the worker that the operation is not standard, so as to prevent the worker from directly stepping on the elastic dust removal rod and causing loss.

[0045] Embodiment 3

[0046] A method for using an efficient dust removal system for a dust-free workshop. The worker walks in from the entrance of the dust removal walkway, and each of the two feet enters a dust removal walkway respectively. The infrared sensor is triggered, and the electric rolling brush starts to work to clean the soles and the stripe gaps inside the soles horizontally; when the worker passes through the dust removal walkway, the worker walks with small steps close to the ground, that is, the soles move along the baffle. When the shoes move forward, they touch the elastic dust removal rods and separate the elastic dust removal rods, triggering the switch or the electric control valve to open for dust suction operation on the shoe upper; after the worker walks away, the elastic dust removal rods return to the initial position, the switch or the electric control valve closes, and the elastic dust removal rods will naturally swing during the rebound process to form a slap and brush on the back of the shoes (the heel part), so as to clean the back of the shoes where it is easy to form a cleaning dead angle.

[0047] It should be noted that since the bristles may touch the instep or ankle of a person, in order to prevent the bristles from touching the human skin and causing discomfort, it is advisable for the worker to wear socks with a slightly higher sock tube when passing through the dust removal walkway.

[0048] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the embodiments shown and described herein.
