Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a filter screen structure for a dust-free workshop. Background Art

[0002] A dust-free workshop, also known as a clean room, clean plant, clean room or dust-free room, refers to a room that removes pollutants such as particles, harmful air, and bacteria from the air within a certain space, and controls the indoor temperature, cleanliness, indoor pressure, air flow speed and air flow distribution, noise, vibration, lighting, and static electricity within a certain required range. No matter how the external air conditions change, the room can maintain the required cleanliness, temperature, humidity, and pressure. Its main function is to control the cleanliness, temperature, and humidity of the atmosphere that the product comes into contact with, and to ensure that the product is produced and manufactured in a good environmental space.

[0003] The main function of the filter structure in the dust-free workshop is to filter particles and impurities in the air to ensure the cleanliness of the air. The filter structure is usually composed of filter media and a support frame. The filter medium is the core of the filter and can capture and fix tiny dust particles; the support frame fixes the filter medium and provides mechanical strength to prevent unfiltered air from bypassing the filter and entering the dust-free workshop.

[0004] When replacing the filter, if the operation is improper, the dust may be vibrated and scattered. This is mainly because the filter plays the role of filtering and blocking dust in the vacuum cleaner or dust-free workshop, so a large amount of dust and impurities will accumulate on the filter. During the removal of the old filter, if you are not careful or operate too violently, the dust on the filter may be vibrated and scattered, which will not only pollute the surrounding environment, but also affect the health of the operator. Therefore, when replacing the filter, special attention should be paid to the operation method and steps to avoid dust flying.

[0005] The patent with the current publication number CN213760964U discloses a filter structure, including a shell and a filter element arranged in the shell, and also includes a flap. A receiving groove for installing the flap is opened on the side wall of the shell, and the side of the flap is rotatably connected to the corresponding side wall of the receiving groove. When the flap is rotated to a state where the first edge is in abutment with the bottom wall of the receiving groove, the second edge of the flap opposite to the first edge is tilted out of the receiving groove and forms a socket between the bottom wall of the receiving groove. Although the above device solves the problem that the handle does not occupy the assembly space of the filter element.

[0006] However, the above solution still has the following problems:

[0007] When the filter needs to be replaced, due to long-term accumulation of dust, a large amount of dust accumulates on the outside of the filter. When the dust thickness reaches a certain level, the vibration generated by replacing the filter will vibrate the dust into the air, and the dust will fly everywhere and pollute the environment; and the staff needs to clean the filter in the connecting structure around the filter, which increases the workload. Utility Model Content

[0008] In view of the deficiencies of the prior art, the utility model provides a filter screen structure for a dust-free workshop to at least solve one of the problems raised by the background technology, such as: ensuring that dust and the like will not splash and pollute the environment when the filter screen is replaced.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filter screen structure for a dust-free workshop, comprising a support frame main body and a filter screen connected to the support frame main body, the support frame main body and the filter screen are detachably arranged, a filter port is provided on the surface of the support frame main body, a cavity is provided at the top and bottom of the support frame main body, a rotating device is installed in the cavity, a dustproof cloth is provided on the outside of the rotating device, a columnar paddle is provided on one side of the support frame main body, and the columnar paddle is fitly connected to one end of the rotating device.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figures 1 to 5 As shown, a filter screen structure for a dust-free workshop includes a support frame body 1 and a filter screen 2 connected to the support frame body 1. The support frame body 1 and the filter screen 2 are detachable. A filter port 101 is provided on the surface of the support frame body 1. A cavity 105 is provided at the top and bottom of the support frame body 1. A rotating device 3 is installed in the cavity 105. A dustproof cloth 5 is provided on the outer side of the rotating device 3. A columnar paddle 4 is provided on one side of the support frame body 1. The columnar paddle 4 and one end of the rotating device 3 are fitted and connected.

[0025] like Figure 1As shown, a filter screen structure for a dust-free workshop in the utility model is similar to the existing filter screen structure, such as the filter screen structure disclosed in the patent publication number CN213760964U. The main improvement of the utility model is that the dust can be sealed in the filter screen when the filter screen is replaced, such as Figures 1 to 5 As shown, when a filter screen structure for a dust-free workshop in the utility model is used, a worker rotates the columnar paddle 4, and the columnar paddle 4 drives the rotating device 3 in the support frame body 1 to rotate, and the dustproof cloth 5 outside the rotating device 3 is rotated to the extent that the filter port 101 of the support frame body 1 leaks out, so that the surface of the filter screen 2 installed in the support frame body 1 leaks out, and the filter screen medium can filter the dust, and the dust is concentrated on the surface of the filter screen 2 to achieve the effect of purifying the air; when a new filter screen 2 needs to be replaced, the columnar paddle 4 is rotated, and the columnar paddle 4 is rotated. The shaped paddle 4 drives the rotating device 3 to rotate the dustproof cloth 5 to the extent of closing the filter port 101, and the dust is sealed in the space between the dustproof cloth 5 and the filter 2. When the support frame body 1 is removed from the fan, the filter 2 can be subsequently replaced. The filter 2 can be taken out of the support frame body 1 and replaced with a new filter 2, so as to prevent the dust from being too thick and easily splashing into the air when replacing the new filter 2, prevent the dust from polluting the environment, improve the cleanliness of the connection structure around the support frame body 1, and improve the efficiency of the staff in replacing the filter 2.

[0026] like Figure 1 As shown, one end of the filter screen 2 is fixedly connected to a connecting plate 201 , one side of the support frame body 1 is provided with a slot 102 connected to the filter port 101 , and the inner wall of the slot 102 is fitted and connected to the outer side of the connecting plate 201 .

[0027] Specifically, through this setting, the filter 2 can be directly inserted into the interior of the support frame body 1, and can also be quickly separated from the support frame body 1, which is convenient for the staff to quickly replace the new filter 2, thereby improving the work efficiency of the staff, and replacing the new filter 2 does not affect the support frame body 1 and other structures inside the support frame body 1, and can continue to be used.

[0028] like Figure 1 As shown, the rotating device 3 includes a rotating column 301 and a fixed paddle 302 , the two ends of the rotating column 301 are rotatably connected to the inner wall of the cavity 105 , and a plurality of fixed paddles 302 are fixedly connected to the outer side of the rotating column 301 located at the top of the support frame body 1 .

[0029] Specifically, through this arrangement, the rotating device 3 can rotate inside the support frame body 1, driving the dustproof cloth 5 to rotate. The dustproof cloth 5 can rotate to make the filter port 101 in a closed or open state, thereby achieving the effect of controlling dust from leaking into the air and avoiding affecting the operation of the filter 2.

[0030] like Figure 1As shown, the outer side of the fixed paddle 302 is closely connected to the outer side of the columnar paddle 4 , and a rectangular opening 104 is provided on the surface of the support frame body 1 to be rotatably connected to the two ends of the columnar paddle 4 .

[0031] Specifically, through this arrangement, the staff can control the rotating device 3 located in the cavity 105 by controlling the cylindrical paddle 4. The cylindrical paddle 4 connected to the rectangular opening 104 does not occupy the surface of the support frame body 1, and when installing or disassembling the support frame body 1, it avoids affecting the installation between the support frame body 1 and other connecting structures.

[0032] like Figure 1 As shown, the inner walls at the upper and lower ends of the filter port 101 are provided with through channels 103 communicating with the cavity 105 , the dustproof cloth 5 passes through the through channels 103 and is sleeved on the outside of the two rotating columns 301 , and the dustproof cloth 5 is rotatably connected to the outside of the rotating columns 301 .

[0033] Specifically, through this arrangement, the dustproof cloth 5 can pass through the cavity 105 and the outer side of the rotating column 301 to be rotatably connected, thereby saving space inside the support frame body 1, so that the two rotating columns 301 and the dustproof cloth 5 form a rolling roller effect, and the position of the dustproof cloth 5 at the filter port 101 can be adjusted to control the opening and closing of the filter port 101, thereby achieving the effect of preventing dust from splashing.

[0034] like Figure 1 As shown, an opening 501 is formed on the surface of the dustproof cloth 5 .

[0035] Specifically, by arranging the open opening 501 and the dustproof cloth 5 in an aligned manner, when the dustproof cloth 5 is rotated, the open opening 501 and the dustproof cloth 5 that can close the filter opening 101 appear alternately, which can save the space occupied by the dustproof cloth 5 in the support frame body 1 and can also cover and open the filter opening 101.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
