DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Please see the attached Figure 1 and attached Figure 5 , a dismantling device with dust removal and filtering functions, comprising a mobile body, a dust removal box 2, an air suction port 3, a dust removal component, a filter component, a connecting plate 19, an electric push rod 20, a cutting machine 21 and an electric hammer 22; the dust removal box 2 is mounted on the mobile body, and the filter component is movably plugged into the middle of the dust removal box 2 to divide the dust removal box 2 into an upper dust removal space and a lower filter space, and the upper dust removal space and the lower filter space are connected through the filter component; the dust removal component is arranged in the dust removal box 2, the air suction port 3 is mounted on the side end surface of the dust removal box 2, one end of the air suction port 3 is connected to the upper dust removal space, and the other end of the air suction port 3 is connected to the external environment; the connecting plate 19 is mounted on the side end surface of the dust removal box 2 and is located below the air suction port 3, the cutting machine 21 is liftably mounted on the bottom of the connecting plate 19 through the electric push rod 20, and the cutting disc of the cutting machine 21 is arranged facing the ground, the electric hammer 22 is mounted on the bottom of the connecting plate 19, and the hammer body of the electric hammer 22 is arranged facing the wall.

[0026] The mobile body is used for the flexible movement of the entire demolition device at the construction site. After the demolition device moves to the demolition construction location, the telescopic end can be extended by the electric push rod 20. The telescopic end of the electric push rod 20 lowers the cutter 21 to the ground, so that the ground can be cut by the cutting disk. The cutting can be positioned or the demolition device can be moved while cutting, thus realizing the demolition of old decorations on the ground. At the same time, the electric hammer 22 can also be started to make the hammer body of the electric hammer 22 knock against the wall. The knocking can be positioned or the demolition device can be moved while knocking, thus realizing the demolition of old decorations on the wall. The cutter 21 and the electric hammer 22 controlled by the electric push rod 20 are both commonly used demolition tools in this field. Their working process and working principle will not be described in detail here. Other demolition tools can also be selected and installed on the connecting plate 19 according to actual use needs.

[0027] Preferably, a high-speed fan can be installed in the air intake 3. The high-speed fan can generate negative pressure in the air intake 3, thereby quickly drawing air into the air intake 3. The rapid flow of air also brings dust generated by cutting and hammering into the air intake 3, thereby achieving the purpose of dust removal. The diameter of the air intake 3 and the power of the high-speed fan can be adaptively selected according to the actual dust situation to ensure the dust removal effect.

[0028] After dust-laden air enters the upper dust removal chamber of dust removal box 2 through air intake 3, the dust removal assembly sprays water to remove the dust from the air, mixing it with the water. The filter assembly filters the dust from the water, allowing it to be recycled. A one-way valve can be installed on dust removal box 2 to unidirectionally discharge the dust-removed air and maintain pressure balance within the dust removal box 2.

[0029] Please see the attached Figure 1 The mobile body includes a base plate 1, universal wheels 23 and armrests 24; several universal wheels 23 are installed at intervals at the bottom corners of the base plate 1, the armrests 24 are installed on the top of the base plate 1, and the armrests 24 and the connecting plate 19 are respectively located at the two ends of the base plate 1; the dust removal box 2 is arranged on the base plate 1 and is located next to the armrests 24.

[0030] Preferably, the base plate 1 can be a rectangular plate, and universal wheels 23 are installed at the four corners of the rectangular plate. The number of universal wheels 23 can also be adaptively increased according to actual load and movement requirements. The universal wheels 23 can be silent universal wheels with braking structures in the existing technology.

[0031] The handrail 24 can be installed at one end of the base plate 1 and extend obliquely upward to facilitate construction workers to hold and control the movement and steering of the entire device.

[0032] Please see the attached Figure 2 The dust removal assembly includes a water distribution nozzle plate 4, a water storage tank 13 and a water supply mechanism; the water distribution nozzle plate 4 is installed on the top of the upper dust removal space, so that several nozzles evenly distributed on the water distribution nozzle plate 4 are arranged facing the lower filter space; the water storage tank 13 is arranged in the lower filter space, and the filter assembly is arranged between the water storage tank 13 and the water distribution nozzle plate 4, and the installation height of the filter assembly is lower than the installation height of the air suction port 3; one end of the water supply mechanism is connected to the water storage tank 13, and the other end of the water supply mechanism is connected to the water distribution nozzle plate 4.

[0033] Preferably, the uniformly distributed nozzle plate 4 consists of a uniformly distributed plate and a nozzle. The uniformly distributed plate is used to receive the water pumped by the water supply mechanism and distribute it evenly to each nozzle through the water pipe. The nozzle can adopt the atomizing nozzle of the existing technology, so that the water is atomized and sprayed out, and the water mist is used to wrap the dust in the air and bring it down to the filter component to achieve the purpose of dust removal.

[0034] The size of the uniform distribution plate and the number of nozzles can be adaptively selected according to the cross-sectional size of the upper dust removal space, so that the spray range of the nozzle covers the entire cross-sectional area of the upper dust removal space to ensure high efficiency and adequacy of dust removal.

[0035] The water supply mechanism is used to pump the water in the water tank 13 to the water distribution nozzle plate 4. After the water distribution nozzle plate 4 removes dust from the air, the dust and water are filtered and separated by the filter component, so that the clean water flows back to the water tank 13 through the filter component, which is convenient for water recycling and saves water resources while ensuring the dust removal effect.

[0036] Please see the attached Figure 3The water supply mechanism includes a first connecting pipe 14, a water pump 15 and a delivery pipe 16; one end of the first connecting pipe 14 is connected to the water storage tank 13, the other end of the first connecting pipe 14 is connected to the water inlet end of the water pump 15, the water outlet end of the water pump 15 is connected to one end of the delivery pipe 16, and the other end of the delivery pipe 16 is connected to the water distribution end of the water distribution nozzle plate 4; the water pump 15 is installed on the top of the dust removal box 2, and the first connecting pipe 14 is located on the back of the dust removal box 2.

[0037] The power of the water pump 15 can be adaptively selected according to the actual water pumping demand to ensure that the water in the water tank 13 is pumped into the water distribution nozzle plate 4 through the first connecting pipe 14 and the delivery pipe 16 to meet the water demand of the water distribution nozzle plate 4.

[0038] Please see the attached Figure 2 and attached Figure 4 The filter assembly includes a fixed plate 7, a fixed frame 10, a filter screen 12 and a disassembly mechanism; the fixed frame 10 is a frame structure, and the filter screen 12 is detachably embedded in the fixed frame 10; one end of the fixed frame 10 is fixedly connected to the fixed plate 7, and an open groove (not shown in the figure) is formed in the middle of the front end of the dust removal box 2. The filter screen 12 is inserted into the middle of the dust removal box 2 through the fixed frame 10 and is located between the water distribution nozzle plate 4 and the water storage tank 13. The fixed plate 7 is movable and covered on the open groove of the dust removal box 2; the disassembly mechanism is connected between the fixed plate 7 and the outer wall of the dust removal box 2.

[0039] The fixed frame 10 can be made of a hard material and is used to embed the filter 12. The filter 12 and the fixed frame 10 can be connected by means of a snap or the like, which makes disassembly and assembly easy and convenient for replacing the filter 12. The filter 12 is placed between the water distribution nozzle plate 4 and the water storage tank 13 and is lower than the air intake 3. After the air mixed with dust enters the upper dust removal space through the air intake 3, the air is sprayed by the water distribution nozzle plate 4 to reduce dust, and the water containing dust falls onto the filter 12. The mesh size of the filter 12 can be adaptively selected according to the actual dust removal needs to ensure that the dust and water are fully separated, so as to facilitate the recycling of the water after it seeps into the water storage tank 13.

[0040] The disassembly mechanism is used to pull the fixing plate 7 , thereby driving the fixing frame 10 and the filter 12 to be pulled out of the dust removal box 2 , so as to facilitate the replacement operation of the filter 12 .

[0041] Please see the attached Figure 4 The disassembly mechanism includes a fixed block 6, a tension spring 8 and a pull rod 9; the two ends of the fixed plate 7 extend to the front ends of the dust removal box 2, and a pair of fixed blocks 6 are symmetrically installed on the outer walls of the two sides of the dust removal box 2. A pair of tension springs 8 are respectively connected between the two ends of the fixed plate 7 and the pair of fixed blocks 6, so that the fixed plate 7 can be elastically covered on the opening groove of the dust removal box 2; the pull rod 9 is installed on the side of the fixed plate 7 away from the dust removal box 2.

[0042] Preferably, the fixing block 6 can be a hollow cylindrical structure, and one end of the tension spring 8 can be installed in the fixing block 6, which is firmly installed and can serve as a guide and limiter for pulling. When the fixing plate 7 is pulled outward (away from the dust removal box 2) via the pull rod 9, the movable fixing frame 10 and the filter 12 are pulled outward synchronously, thereby facilitating the replacement of the filter 12.

[0043] When pulled outward, the tension spring 8 is stretched to generate elastic force, so that the fixing plate 7 is pushed inward and reset by the elastic force, thereby completing the reset installation of the new filter screen 12, which is convenient and labor-saving to operate.

[0044] Please see the attached Figure 4 , fixed frames 5 are respectively installed on the inner walls of both sides of the dust removal box 2, and a slide groove (not shown in the figure) is formed on the surface of the two fixing frames 5 away from the inner wall of the dust removal box 2; slide plates 11 are respectively provided at the edges of both ends of the fixed frame 10, and the slide plates 11 are slidably embedded in the slide grooves, so that the fixed frame 10 and the filter screen 12 can be pulled out and arranged in the dust removal box 2.

[0045] Through the horizontal sliding cooperation between the sliding groove in the fixing frame 5 and the sliding plate 11, the fixing frame 10 and the filter screen 12 can be pulled in the horizontal plane. The pulling action is highly stable and controllable and is not prone to deformation and damage.

[0046] Please see the attached Figure 1 The front bottom of the water storage tank 13 is connected to a second connecting pipe 17 , the second connecting pipe 17 passes through the front end of the dust removal box 2 and is installed with a control valve 18 .

[0047] By opening the control valve 18, the water in the water tank 13 can be drained through the second connecting pipe 17, making it easier to replace and clean the water tank 13. Preferably, a movable door can be provided on the dust removal box 2 to facilitate maintenance of the dust removal and filter components inside. When the dismantling device is in use, the control valve 18 is closed to prevent the water in the water tank 13 from leaking.

[0048] Please see the attached Figure 1 To the attached Figure 5 The working process and working principle of the utility model in the demolition operation are as follows:

[0049] The construction worker holds the handrail 24 and moves the entire demolition device to the construction position through the universal wheel 23. After locking the universal wheel 23, the cutter 21 can be pushed downward by the electric push rod 20. The cutting disc of the cutter 21 cuts and demolishes the ground, and the hammer body of the electric hammer 22 knocks on the wall to perform the demolition operation.

[0050] During the demolition process, dust generated is drawn in through air intake 3. The dust-laden air enters the upper dust removal space of dust removal box 2. Water pump 15 is activated, pumping water from water tank 13 through first connecting pipe 14 and delivery pipe 16 to water distribution nozzle plate 4. The water is evenly distributed to each nozzle and then sprayed into the upper dust removal space, flushing the dust from the air. The dust, along with the water mist, falls onto filter screen 12, where it is filtered and retained. Water permeates filter screen 12 and enters water tank 13 in the lower filter space, where it can be recycled.

[0051] After the construction is completed, the control valve 18 can be opened to discharge the sewage from the water tank 13 through the second connecting pipe 17. When the filter 12 needs to be replaced, hold the pull rod 9 and pull the fixed plate 7 away from the dust box 2. The slide plate 11 slides along the slide groove in the fixed frame 5 to pull the filter 12 out of the open slot of the dust box 2. At this time, the two tension springs 8 are stretched and charged. Remove the filter 12 and install the new filter into the fixed frame 10. After replacing the filter 12, use the elastic force of the tension spring 8 to drive the fixed plate 7 to move closer to the dust box 2 and reset the filter 12.

[0052] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
