In addition, when a device is said to "include" a certain component, unless otherwise stated, it does not exclude other components, but means that other components may be included.
[0038] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.
[0039] The embodiment of the present application discloses a filtering type dust collecting and ventilation device.
[0040] A filtering dust collecting ventilation equipment, reference Figure 1As shown, it includes a mounting base 1, an exhaust member 2, a filter member 3 and a discharge pipe 4. The exhaust member 2 is mounted on the mounting base 1. The exhaust member 2 is provided with a connecting pipe 5. The mounting base 1 is provided with components such as a switch and a winding rack. The exhaust member 2 can adopt an exhaust fan, and the power cord of the exhaust fan can be wound on the winding rack and electrically connected to the switch. The exhaust fan is mainly used to drive the surrounding air and dust in the air to flow toward the exhaust fan.
[0041] The filter element 3 is installed on the connecting pipe 5 and is connected to the connecting pipe 5. The exhaust fan can transmit the exhaust air pressure to the filter element 3 through the connecting pipe 5. The exhaust fan is used to form a negative pressure at the filter element 3, so that the surrounding air and dust in the air rush into the filter element 3.
[0042] The discharge pipe 4 is connected to the exhaust element 2. When the surrounding air and dust in the air enter the filter element 3, the interior of the filter element 3 has a fine pore structure, so that the air can pass through the filter element 3 and enter the exhaust fan, and the air is discharged from the discharge pipe 4 through the exhaust fan. The diameter of the dust is larger than the fine pores inside the filter element 3, so that the dust is intercepted on the filter element 3 and is adsorbed on the filter element 3 by the exhaust effect of the exhaust fan and cannot continue to drift into the air, thereby improving the surrounding working environment, improving the cleanliness of the product in the plastic granulation process, and then improving the product yield.
[0043] For further reference, Figure 2 As shown, the connecting pipe 5 is provided with a plug connector 6, which can be a plug socket and a plug rod. The plug socket is installed at the pipe opening of the connecting pipe 5, but does not completely cover the pipe opening of the connecting pipe 5, and the plug rod is fixedly installed on the plug socket.
[0044] An insertion port 31 is provided at the axis of the filter element 3, and the insertion port 31 is opened from one end of the filter element 3 to the other end, so that the filter element 3 can be plugged into the connector 6 through the insertion port 31. When the filter element 3 needs to be replaced or maintained, the filter element 3 can be pulled out from the connector 6, which is convenient for disassembly.
[0045] Further, refer to Figure 2 As shown, a limiting nut 61 is provided on the connector 6, and the limiting nut 61 is preferably a butterfly nut. The butterfly nut has a butterfly-shaped hanging ear, which provides a fulcrum for convenient twisting and rotation. An external thread is provided on the surface of the connector 6, and the limiting nut 61 is screwed to the connector 6 through the external thread. The limiting nut 61 can mainly fasten the filter element 3. When the filter element 3 is inserted on the connector 6, the limiting nut 61 is screwed into the connector 6 until it is tight against the filter element 3, thereby achieving the fastening effect on the filter element 3. This can avoid the situation in which the filter element 3 shakes or deviates due to excessive wind pressure during use, resulting in air leakage in the connecting pipe 5, and also prevent the filter element 3 from being taken out at will, providing a partial anti-theft effect.
[0046] Furthermore, the outer wall of the filter element 3 is cylindrical, and the cylindrical shape enables air to be exhausted in a 360-degree circular direction around it, thereby avoiding the situation where the dust at any angle is too large and dead corners of air extraction occur.
[0047] In some embodiments, reference Figure 3 As shown, a connecting plate 51 is provided at the pipe mouth of the connecting pipe 5, the inner diameter of the connecting plate 51 fits with the outer diameter of the filter element 3, and the inner concave surface of the connecting plate 51 is an arc surface. The arc surface can reserve space between the pipe mouth of the connecting pipe 5 and the filter element 3, so as to facilitate the unified extraction of air.
[0048] When the filter element 3 is inserted into the connector 6, the bottom of the filter element 3 is inserted into the connecting disk 51. Since the inner diameter of the connecting disk 51 fits the outer diameter of the filter element 3, when the filter element 3 is inserted into the connecting disk 51, the outer wall of the filter element 3 is pressed against the inner wall of the connecting disk 51, thereby reducing the appearance of gaps and preventing air and dust from entering the connecting pipe 5 through the gaps without passing through the filter element 3 during ventilation.
[0049] The function of the connecting plate 51 is to expand the installation area of the filter element 3, which not only provides stable support for the filter element 3, but also reduces the air leakage caused by the gap between the filter element 3 and the connecting pipe 5 after insertion.
[0050] In some embodiments, reference Figure 4 As shown, the filter element 3 is also provided with an adhesive portion 32, and the adhesive portion 32 can be made of a double-sided adhesive strip or Velcro. Taking Velcro as an example, the adhesive portion 32 is adhered to the two ends of the side wall of the filter element 3, which means that the hook surface or suede surface of the Velcro is adhered to the two ends of the cylindrical filter element 3 by using tools such as glue, and a gauze layer 33 is adhered to the adhesive portion 32. The gauze layer 33 is made of textile gauze and has relatively large holes. The surface of the gauze layer 33 is sewn with the hook surface or suede surface of the Velcro, wherein the Velcro surface on the surface of the gauze layer 33 is different from the Velcro surface on the filter element 3 to ensure that the gauze layer 33 can be adhered to the filter element 3 by using Velcro.
[0051] Specifically, the gauze layer 33 is adhered to the filter element 3 by using the adhesive portion 32, so that the surface of the filter element 3 is covered with a layer of gauze layer 33. When the filter element 3 is used for too long, too much dust will adhere to the inside of the filter element 3, resulting in a decrease in the filtering effect. Therefore, it is necessary to replace it at intervals. The maintenance cost is relatively high. Therefore, the adhesive portion 32 and the gauze layer 33 are provided on the filter element 3. The gauze layer 33 can pre-intercept the dust, so that the dust that actually enters the filter element 3 is reduced, thereby increasing the service life of the filter element 3 and extending the interval time required for replacement.
[0052] After the gauze layer 33 intercepts the dust, the dust will be continuously adsorbed by the filter element 3 due to the suction effect of the exhaust element 2, and will be adsorbed on the gauze layer 33 and cannot float away, which can also play a role in reducing dust.
[0053] After a certain period of time, the surface of the gauze layer 33 will be covered with dust. Therefore, the gauze layer 33 can be replaced by tearing it off from the adhesive portion 32, or the gauze layer 33 can be taken out to clean the dust or wash the gauze layer 33, which will not affect the normal operation of the filtration. The maintenance cost of replacing the gauze layer 33 or cleaning the gauze layer 33 is much lower than the maintenance cost of replacing the filter element 3.
[0054] Furthermore, liquids such as water stains or oil stains may be attached to the surface of the gauze layer 33, that is, when the gauze layer 33 is pasted on the pasting part 32, the gauze layer 33 may be soaked first. The soaking material may be water or lubricating oil, so that when dust is attached to the gauze layer 33, the dust is subjected to the tension of the liquid, and the adhesion force is greater, thereby preventing the dust from falling. When water is used, the water will evaporate due to the influence of wind, while the evaporation rate of oil stains is slower than that of water, but the cost of use is also higher. Therefore, the soaking attachment is used according to one's own needs.
[0055] In some embodiments, reference Figure 5 The outer wall of the exhaust fan 2 is provided with a soundproof cover 21. The soundproof cover 21 can be made of a foam material or a plastic material seat shell, and the interior is filled with a part of a porous structure, such as a soundproof sponge. The soundproof cover 21 can reduce the noise generated by the exhaust fan during use and reduce the impact on the surrounding environment.
[0056] In some embodiments, reference Figure 5 As shown, the bottom of the mounting base 1 is provided with moving wheels 11, and the moving wheels 11 are preferably universal wheels. A push-pull handle 12 is provided on the side, and the push-pull handle 12 can provide a fulcrum for the mobile mounting base 1, so that the user or worker can pull the mounting base 1 conveniently. The mounting base 1 is moved by the moving wheels 11, which is convenient for transportation and changing the purification location, and provides convenience of use.
[0057] Among them, the push-pull handle 12 can be provided with an extension frame, which can be extended to the position of the filter element 3 and can abut against the filter. The extension frame can provide other support effects for the filter element 3 in addition to the connecting pipe 5, thereby preventing the filter element 3 from shaking or swaying due to excessive wind pressure, thereby affecting the filtering effect.
[0058] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
