[0001] The invention relates to the technical field of dust treatment devices, and in particular to a dust treatment device for indoor decoration. Background Art

[0002] With the continuous development of the construction industry and the improvement of people's living standards, indoor decoration activities are becoming more and more frequent. However, a large amount of smoke and dust will be generated during the indoor decoration process, which not only poses a serious threat to the health of construction workers, but also pollutes the indoor environment, affecting the quality of decoration and subsequent living experience.

[0003] As a common treatment device, cyclone separators can separate smoke and dust to a certain extent and are an important tool to ensure the cleanliness of the decoration environment. However, when actually used in indoor decoration scenarios, existing cyclone separators have exposed many problems.

[0004] The smoke generated by indoor decoration is characterized by large quantity and complex composition. This makes the existing cyclone separators face a sharp increase in processing pressure when facing a large amount of smoke. Its processing capacity is often unable to meet the high intensity of smoke generated at the decoration site, resulting in poor separation effect. A large amount of smoke cannot be effectively separated and discharged into the air, which may also cause equipment failure and affect the normal progress of the decoration project.

[0008] Furthermore, the filter screen can be arranged to rotate around a first direction, and a scraper is arranged at the inner end of the blocking block, and a dust collecting chamber is arranged on the outer cylinder, and the dust collecting chamber is communicated with the filter cavity.

[0009] Furthermore, an inner rotating wheel is arranged in the inner chamber, and an outer rotating wheel is arranged in the outer chamber. Both the inner rotating wheel and the outer rotating wheel are in contact with the filter screen, and both the inner rotating wheel and the outer rotating wheel are rotatable around a first direction, and the rotation directions of the inner rotating wheel and the outer rotating wheel are opposite.

[0010] Furthermore, the filter screen is elastic, and a driving member is arranged on the frame, and the driving member can drive the filter screen to move along the second direction; a collecting chamber is arranged on the outer cylinder, and the collecting chamber and the driving member are located on the same side.

[0011] Further, the driving member and the air inlet are arranged opposite to each other in the second direction.

[0012] Furthermore, the driving member is a hydraulic telescopic rod, which passes through the outer tube along the second direction. The hydraulic telescopic rod moves along the second direction and can abut against the filter screen, thereby enabling the filter screen to move along the second direction.

[0013] Furthermore, an insert block is provided at the lower end of the upper cylinder, which is inserted into the embedding groove and abuts against the upper end of the filter screen to seal the upper end of the inner chamber; the lower end of the filter screen abuts against the inner bottom wall of the embedding groove.

After the gas enters the filter chamber of the outer chamber from the air inlet, the plugging piece restricts the smoke from flowing from the filter chamber to the transition chamber in the outer chamber. Therefore, the smoke will move from the outside to the inside, pass through the filter screen corresponding to the filter chamber and enter the inner chamber. In this process, the filter screen corresponding to the filter chamber filters the smoke with a diameter greater than the preset value, and the smoke with a diameter less than the preset value will pass through the filter screen and come to the inner chamber. After the smoke passes through the inner chamber, the smoke will continue to move from the inside to the outside and come to the transition chamber of the outer chamber again, and enter the upper cylinder from the connecting groove in the transition chamber. The internal structure of the upper cylinder and the internal structure of the lower cylinder are the same as the cyclone separator structure in the prior art. After the smoke enters the upper cylinder from the connecting groove along the tangent direction of the upper cylinder, the smoke will rotate downward in a spiral, and the solid particles will be thrown to the inner wall of the upper cylinder under the action of centrifugal force, and fall into the dust collecting port under the action of gravity, and the purified gas will be discharged from the outlet pipe. The filter is used as the front end of the cyclone separation and dust removal. Before the cyclone separation method is used for dust removal, the filter is first used for preliminary filtration to filter the smoke with a diameter greater than the preset value, and the filtered smoke can be directly sent into the upper cylinder for secondary dust removal, which greatly reduces the processing pressure of the dust treatment device for indoor decoration.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] An embodiment of a dust treatment device for indoor decoration of the present invention is as follows Figures 1 to 9 shown.

[0022] A dust treatment device for indoor decoration includes a frame 100, an upper cylinder 200, a lower cylinder 300 and a filter 400. The upper cylinder 200 and the lower cylinder 300 are arranged in sequence in a first direction, and the first direction is a vertical direction. The upper cylinder 200 is cylindrical, and an air outlet pipe 210 is arranged at the upper end of the upper cylinder 200. The lower cylinder 300 is conical, and a dust collecting port 301 is provided on the lower cylinder 300. The lower cylinder 300 is fixedly connected to the frame 100. The upper cylinder 200 is located at the upper end of the lower cylinder 300, and the lower end of the upper cylinder 200 is fixedly connected to the large end of the lower cylinder 300. An embedding groove is provided on the lower cylinder 300, and the embedding groove is coaxially arranged with the lower cylinder 300. The filter 400 is nested in the embedding groove and is arranged in a conical shape. The filter 400 is used to filter smoke with a diameter greater than a preset value.

[0023] The lower cylinder 300 located at the inner and outer sides of the filter 400 is respectively referred to as the inner cylinder 310 and the outer cylinder 320, and the side close to the vertical center axis of the lower cylinder 300 along the second direction is referred to as the inner side, and the side away from the vertical center axis of the lower cylinder 300 is referred to as the outer side. That is, the inner cylinder 310 is located inside the filter 400, and the outer cylinder 320 is located outside the filter 400. The second direction is the radial direction of the lower cylinder 300.

[0024] An inner chamber 330 is defined between the inner tube 310 and the filter screen 400, and an outer chamber 340 is defined between the outer tube 320 and the filter screen 400. An air inlet 321 is provided on the outer tube 320, and the air inlet 321 is connected to the outer chamber 340 for introducing smoke. A plugging member is provided in the outer chamber 340, and the plugging member divides the outer chamber 340 into a filter chamber 341 and a transition chamber 342, and the filter chamber 341 and the transition chamber 342 are independent of each other, that is, smoke can only flow in the filter chamber 341 after entering the outer chamber 340, and the smoke is restricted from flowing from the filter chamber 341 to the transition chamber 342 in the outer chamber 340, or from the transition chamber 342 to the filter chamber 341. In the initial state, the filter cavity 341 is arranged toward the air inlet 321 , and a connecting groove 220 is provided on the upper cylinder 200 . The connecting groove 220 is spiral-shaped, and connects the upper cylinder 200 and the transition cavity 342 .

[0025] In this embodiment, the filter screen 400 is embedded in the lower cylinder 300 and a blocking member is provided. When in use, the gas is introduced from the air inlet 321 by using an air pump. After the gas enters the filter chamber 341 of the outer chamber 340 from the air inlet 321, the blocking member restricts the smoke from flowing from the filter chamber 341 to the transition chamber 342 in the outer chamber 340. Therefore, the smoke moves from the outside to the inside, passes through the filter screen 400 corresponding to the filter chamber 341 and enters the inner chamber 330. In this process, the filter screen 400 corresponding to the filter chamber 341 filters the smoke with a diameter greater than the preset value, while the smoke with a diameter less than the preset value passes through the filter screen 400 and enters the inner chamber 330. After passing through the inner chamber 330, the smoke will continue to move from the inside to the outside and enter the transition chamber 342 of the outer chamber 340 again, and enter the upper cylinder 200 from the connecting groove 220 in the transition chamber 342.

[0026] The internal structure of the upper cylinder 200 and the internal structure of the lower cylinder 300 are the same as the cyclone separator structure in the prior art. After the smoke enters the upper cylinder 200 from the connecting groove 220 along the tangent direction of the upper cylinder 200, the smoke will rotate downward in a spiral. The solid particles are thrown toward the inner wall of the upper cylinder 200 under the action of centrifugal force and fall into the dust collecting port 301 under the action of gravity. The purified gas is discharged from the outlet pipe 210.

[0027] That is, this embodiment uses the filter 400 as the front end of the cyclone separation dust removal. Before the cyclone separation method is used for dust removal, the filter 400 is first used for preliminary filtration to filter out the smoke dust with a diameter greater than a preset value, and the filtered smoke dust can be directly sent into the upper cylinder 200 for secondary dust removal, which greatly reduces the processing pressure of the dust treatment device for indoor decoration.

[0028] In this embodiment, the blocking member includes two blocking blocks 500 , both of which are disposed in the outer chamber 340 and are sequentially disposed around the first direction in the outer chamber 340 , and the two blocking blocks 500 are slidably sealed with the filter screen 400 .

[0029] By providing two blocking blocks 500, when smoke enters between the two blocking blocks 500 from the air inlet 321, that is, when entering the filter chamber 341, it will be blocked by the two blocking blocks 500 and basically cannot pass through. Therefore, smoke can only enter the inner chamber 330 from the outside to the inside through the filter screen 400 corresponding to the filter chamber 341, and then enter the transition chamber 342 of the outer chamber 340 from the inside to the outside from the inner chamber 330. Due to the restriction of the blocking blocks 500, the smoke in the transition chamber 342 cannot return to the filter chamber 341.

[0030] Furthermore, an insert block 230 is provided at the lower end of the upper cylinder 200, and the insert block 230 is inserted into the embedding groove and abuts against the upper end of the filter screen 400 to seal the upper end of the inner chamber 330. The lower end of the filter screen 400 abuts against the inner bottom wall of the embedding groove.

[0031] The inner chamber 330 is relatively sealed by providing the insert block 230, so that smoke can only flow from the inner chamber 330 to the outer chamber 340 through the filter screen 400. That is, after entering the inner chamber 330, smoke will not escape everywhere.

[0032] In this embodiment, the filter screen 400 is rotatable about a first direction, a scraper is provided at the inner end of the blocking block 500 , a dust collecting chamber 322 is provided on the outer cylinder 320 , and the dust collecting chamber 322 is communicated with the filter cavity 341 .

[0033] Specifically, an inner rotating wheel 331 is provided in the inner chamber 330, and an outer rotating wheel 343 is provided in the outer chamber 340. Both the inner rotating wheel 331 and the outer rotating wheel 343 are in contact with the filter screen 400. Two motors are provided in the lower cylinder 300, and the inner rotating wheel 331 and the outer rotating wheel 343 are respectively installed on the motors, so that the inner rotating wheel 331 and the outer rotating wheel 343 can be set to rotate around a first direction, and the rotation directions of the inner rotating wheel 331 and the outer rotating wheel 343 are opposite.

[0034] Further, two inner rotating wheels 331 are provided, and the two inner rotating wheels 331 are arranged in sequence around the first direction in the inner chamber 330 and are both in contact with the filter screen 400. By providing two inner rotating wheels 331, the stability of the transmission is increased.

[0035] By enabling the filter 400 to rotate around the first direction, when the filter 400 corresponding to the filter chamber 341 needs to be cleaned, the motor is started to drive the inner wheel 331 and the outer wheel 343 to rotate. The rotation of the inner wheel 331 and the outer wheel 343 will drive the filter 400 to rotate through friction, so that the filter 400 and the scraper on the blocking block 500 will rotate relative to each other, and the scraper can compact and scrape off the smoke and dust attached to the filter 400 to a certain extent, and the scraped smoke and dust will fall into the dust collecting chamber 322, which is convenient for manual cleaning.

[0036] In this embodiment, the filter screen 400 is elastic, and a driving member is provided on the frame 100, and the driving member can drive the filter screen 400 to move along the second direction. A collecting chamber 323 is provided on the outer cylinder 320, and the collecting chamber 323 and the driving member are located on the same side. Two collecting chambers 323 are provided.

[0037] Specifically, two driving members are provided, and the two driving members are sequentially arranged along the first direction on the frame 100, and the two driving members are respectively located at the upper and lower sides of the filter screen 400. By providing two driving members, the filter screen 400 is subjected to a more uniform force.

[0038] Further, the driving member and the air inlet 321 are arranged opposite to each other in the second direction.

[0039] In this embodiment, the driving member is a hydraulic telescopic rod 600, which passes through the outer tube 320 along the second direction. The hydraulic telescopic rod 600 moves along the second direction and can abut against the filter screen 400, thereby enabling the filter screen 400 to move along the second direction.

[0040] Furthermore, the air inlet 321 is close to the upper side of the filter 400. In the initial state, the distance from the upper hydraulic telescopic rod 600 to the filter 400 along the second direction is smaller than the distance from the lower hydraulic telescopic rod 600 to the filter 400 along the second direction, that is, the upper hydraulic telescopic rod 600 contacts the filter 400 first.

[0041] In this embodiment, a driving member is provided. As the filter 400 rotates, the hydraulic telescopic rod 600 is started, and the filter 400 is pushed inward by the hydraulic telescopic rod 600. When the filter 400 containing smoke and dust (the filter 400 corresponding to the filter chamber 341) rotates to the position of the hydraulic telescopic rod 600, the smoke and dust in the transition chamber 342 corresponding to the hydraulic telescopic rod 600 will be pressurized, so that the smoke and dust can be squeezed through the filter 400, and the smoke and dust on the filter 400 are recoiled to fall. On the basis of scraper cleaning, the smoke and dust are further cleaned, and the cleaned smoke and dust will fall into the collection chamber 323, which is convenient for manual processing and realizes self-cleaning of the filter 400. When the hydraulic telescopic rod 600 is retracted, the filter 400 will automatically reset based on its own elasticity.

[0042] Alternatively, an elastic member is disposed between the inner tube 310 and the filter screen 400 , and the elastic member is fixed to the inner tube 310 and abuts against the filter screen 400 , so that the filter screen 400 can be reset under the drive of the elastic member.

[0043] The driving member and the air inlet 321 are arranged opposite to each other in the second direction, which can increase the convection effect of smoke and dust, thereby increasing the recoil force on the filter screen 400 when the filter screen 400 moves inward, that is, when the smoke and dust enter the inner chamber 330 from the outside through the filter cavity 341 through the filter screen 400 from the outside to the inside, it will be diverted in the inner chamber 330, see the attached Figure 6 As shown, part of the smoke goes to the left, and the other part goes to the right, and finally they converge at the position where the driving member is located, generating a certain impact, thereby increasing the recoil force on the filter 400.

[0044] And because the air inlet 321 is close to the upper side of the filter 400, there is more smoke and dust attached to the upper side of the filter 400 (relative to the lower side of the filter 400). Therefore, the hydraulic telescopic rod 600 at the top is first contacted with the filter 400, and the filter 400 can be cleaned from top to bottom, so that the smoke and dust recoil effect of the inner chamber 330 is gathered on the upper side of the filter 400, thereby improving the cleaning effect of the filter 400.

[0045] In this embodiment, two limit blocks 332 are fixedly connected to the inner chamber 330. The two limit blocks 332 are sequentially arranged around the first direction in the inner chamber 330, and air passages are provided on the two limit blocks 332. Two blocking blocks 500 are arranged in one-to-one correspondence with the two limit blocks 332. The blocking blocks 500 and the corresponding limit blocks 332 are respectively located at the inner and outer sides of the filter screen 400, and both are slidably sealed with the filter screen 400.

[0046] Furthermore, a plurality of first limiting blocks 333 are provided in the inner chamber 330, and the plurality of first limiting blocks 333 are evenly distributed around the first direction in the inner chamber 330, and a first flow channel 334 is provided on each of the plurality of first limiting blocks 333. A plurality of second limiting blocks 344 are provided in the outer chamber 340, and the plurality of second limiting blocks 344 are evenly distributed around the first direction in the outer chamber 340, and the plurality of first limiting blocks 333 and the plurality of second limiting blocks 344 are arranged in one-to-one correspondence, and the first limiting blocks 333 and the corresponding second limiting blocks 344 are respectively located at the inner and outer sides of the filter screen 400, and a spacing is left between each of the first limiting blocks 333 and the filter screen 400.

[0047] By setting the limit block 332 and the blocking block 500, the position of the filter 400 directly in contact with the limit block 332 and the blocking block 500 is relatively fixed, that is, the volume of the filter cavity 341 is relatively fixed, thereby making the filter 400 corresponding to the filter cavity 341 more stable.

[0048] By setting the first limiting block 333 and the second limiting block 344, when the hydraulic telescopic rod 600 drives the filter 400 to move along the second direction, the filter 400 can move between the first limiting block 333 and the second limiting block 344 corresponding to the first limiting block 333, and the first flow channel 334 is opened on the first limiting block 333 to facilitate the smoke that has been preliminarily filtered to flow in the inner chamber 330.

[0049] In combination with the above embodiments, the specific working process is as follows: When in use, the gas is introduced from the air inlet 321 by using an air pump. After the gas enters the filter chamber 341 of the outer chamber 340 from the air inlet 321, it will be blocked by the two blocking blocks 500 and basically cannot pass through. Therefore, smoke and dust can only enter the inner chamber 330 from the outside to the inside through the filter screen 400 corresponding to the filter chamber 341. In this process, the filter screen 400 corresponding to the filter chamber 341 filters the smoke and dust with a diameter greater than the preset value, while the smoke and dust with a diameter less than the preset value will pass through the filter screen 400 and enter the inner chamber 330. In the inner chamber 330, the first flow channel 334 is opened on the first limiting block 333, and then the gas enters the transition chamber 342 of the outer chamber 340 from the inner chamber 330 from the inside to the outside, and enters the upper cylinder 200 from the connecting groove 220 in the transition chamber 342.

[0050] The internal structure of the upper cylinder 200 and the internal structure of the lower cylinder 300 are the same as the cyclone separator structure in the prior art. After the smoke enters the upper cylinder 200 from the connecting groove 220 along the tangent direction of the upper cylinder 200, the smoke will rotate downward in a spiral. The solid particles are thrown toward the inner wall of the upper cylinder 200 under the action of centrifugal force and fall into the dust collecting port 301 under the action of gravity. The purified gas is discharged from the outlet pipe 210.

[0051] When the filter 400 corresponding to the filter chamber 341 needs to be cleaned, the motor is started to drive the inner wheel 331 and the outer wheel 343 to rotate. The rotation of the inner wheel 331 and the outer wheel 343 will drive the filter 400 to rotate through friction, so that the filter 400 and the scraper on the blocking block 500 will rotate relative to each other, so that the scraper can compact and scrape off the smoke and dust attached to the filter 400 to a certain extent. The scraped smoke and dust will fall into the dust collecting chamber 322, which is convenient for manual cleaning.

[0052] As the filter 400 rotates, the hydraulic telescopic rod 600 is started and the filter 400 is pushed inward by the hydraulic telescopic rod 600. When the filter 400 containing smoke and dust (the filter 400 corresponding to the filter chamber 341) rotates to the position of the hydraulic telescopic rod 600, the smoke and dust in the transition chamber 342 corresponding to the hydraulic telescopic rod 600 will be pressurized, so that the smoke and dust can be squeezed through the filter 400, and the smoke and dust on the filter 400 are recoiled to fall. On the basis of scraper cleaning, the smoke and dust are further cleaned, and the cleaned smoke and dust will fall into the collection chamber 323, which is convenient for manual processing.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
