Description

Technical Field

[0001] The invention belongs to the technical field of construction site dust treatment, and in particular relates to an environmentally friendly dust recovery device for a construction site. Background Art

[0002] Indoor construction will use a large amount of building materials, and various construction works such as wall painting, floor installation and electrical installation will be carried out in the construction. Therefore, more dust will be generated in the indoor construction site, which will affect the construction workers. Each indoor construction site is separated by various walls, so the indoor construction site will not be too large. Therefore, corresponding dust recovery equipment can be used to recycle the dust generated by the indoor construction site.

[0003] Therefore, when the dust recovery equipment currently used is in use, the equipment itself cannot move quickly, and the volume is not too large. Therefore, each time the dust is recovered, in order to facilitate operation and improve dust collection efficiency, the recovery equipment can only be controlled to perform single-point recovery. Since the equipment does not have the function of single-point position recovery or multi-point position recovery, it is impossible to quickly absorb the indoor dust. At the same time, most of the dust recovery devices used work in a single dust storage mode, and they do not have the function of using the dual storage structure in turn. Therefore, each time the device is used, when the internal space of the storage structure is full, it is necessary to clean the inside. The cleaning process will control the device to stop working, and the indoor construction site will not stop construction work due to cleaning its internal storage space. Therefore, during the cleaning process, the dust in the indoor construction site cannot be recovered in time, resulting in dust accumulation or scattering. To this end, we provide an environmentally friendly dust recovery device for construction sites to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0036] 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. Example

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig.11 This is the first embodiment of the present invention, which provides an environmentally friendly dust recovery device for construction sites. Through the use of the telescopic cylinder 401 and the bellows 104, the device can switch between single-point dust collection and multi-point dust collection. At the same time, the water circulation component 200 and the linkage component 500 are used in coordination to realize the alternating use of the two powder collecting cylinders 403 and the powder storage cylinder 404, so that the cleaning process does not need to stop the dust collection work.

[0038] Specifically, the frame assembly 100 includes a vertical frame 101 and storage blocks 103 located at both end surfaces of the vertical frame 101, a water circulation assembly 200 including a water tank 201 and a circulation pipe 202, the circulation pipe 202 is connected to a water pump inside the water tank 201, a moving assembly 300 including a bottom plate 301 for supporting the vertical frame 101 and the water tank 201, and a storage assembly 400 including two telescopic cylinders 401 symmetrically arranged inside the working chamber 101b, a powder collecting cylinder 403 connected to the upper end surface of the telescopic cylinder 401, and a powder collecting cylinder 403 connected to the lower end surface of the telescopic cylinder 401. The powder storage barrel 404 connected to the surface and the suction fan 402 fixed in the internal position of the vertical frame 101, the linkage assembly 500, includes a linkage tooth plate 501 located directly behind the vertical frame 101 and two symmetrical racks 502 meshing with the linkage tooth plate 501. The suction fan 402 is set to suck the dust in the room into the powder collecting barrel 403, and spray water into the powder collecting barrel 403 through the water tank 201, so as to wet the dust inside the powder collecting barrel 403 and make it slide downward, thereby passing through the telescopic barrel 401, so that the dust is concentrated and stored in the inside of the powder storage barrel 404.

[0039] according to Figure 2 and Fig.10 It can be seen that a working chamber 101b is provided on the front of the vertical frame 101, and vertical openings 103a are provided on the upper end surfaces of the two storage blocks 103, and bellows 104 are provided inside the vertical openings 103a;

[0040] When using the above-mentioned structure, when it is necessary to carry out single-point dust collection on an indoor construction site, the powder collecting cylinder 403, the telescopic cylinder 401 and the powder storage cylinder 404 are assembled and used in coordination. At this time, the suction fan 402 can be directly controlled to work, so as to store the sucked dust in the powder storage cylinder 404. When carrying out multi-point dust collection on the indoor construction site, the telescopic cylinder 401 is taken out from the position between the powder collecting cylinder 403 and the powder storage cylinder 404, so that the powder collecting cylinder 403 and the powder storage cylinder 404 are used in coordination with each other up and down, and the disassembled telescopic cylinder 401 is taken out from the position between the powder collecting cylinder 403 and the powder storage cylinder 404. The telescopic cylinder 401 is set at different positions of the indoor construction site, and the bellows 104 is taken out from the vertical port 103a, so that one end of the bellows 104 is connected to the bottom port of the telescopic cylinder 401, and the other end is connected to one end of the multi-port ball tube 102. Therefore, after the suction fan 402 is controlled to work, dust can be sucked at multiple positions, realizing the switching of single-point dust suction or multi-point dust suction. At the same time, the telescopic cylinder 401 is used, and the telescopic cylinder 401 can be highly pulled to increase the internal space.

[0041] according to Figure 4 , Figure 5 and Figure 6, two three-way ball cylinders 403a arranged linearly in front and back are arranged above the two powder collecting cylinders 403, the rear end surface of the linkage tooth plate 501 is fixed with a linkage rod 501a located inside the vertical frame 101, and a ball block 501b rotating inside the three-way ball cylinder 403a is fixed on the linkage rod 501a, and an L-shaped hole 501b-1 is penetrated inside the ball block 501b, the rear end surface of the powder storage cylinder 404 is fixedly connected to the curved rod 404b located at the rear of the vertical frame 101, and the lower end surface of the rack 502 is provided with a conical piston block 502b used in conjunction with the curved rod 404b;

[0042] When the structure is set as above, as the water stored in the powder storage cylinder 404 gradually increases, the water will also flow into the curved hole 404b-1 and the movable hole 404b-2, and then push the tapered piston block 502b matched therewith. At this time, the tapered piston block 502b drives the rack 502 connected thereto to move upward, and then the rack 502 drives the linkage gear plate 501 to rotate, and thereby controls the other rack 502 to move downward. At the same time, when the linkage gear plate 501 rotates, it drives the two ball blocks 501b to rotate inside the three-way ball cylinder 403a through the linkage rod 501a, and thereby drives the L-shaped hole 501b-1 to rotate slowly, so that the two ports of the L-shaped hole 501b-1 are connected to the other two similar ports of the three-way ball cylinder 403a, so that the other powder collecting cylinder 403 and the powder storage cylinder 404 can be used. At this time, the powder storage cylinder 404 filled with water can be opened to clean the dust and water inside it.

[0043] Further, according to Figure 5 , Figure 6 , Fig. 9 and Fig.13 It can be seen that the upper end surface of the telescopic cylinder 401 is provided with a conical mouth 1 401b, the lower end surface of the powder collecting cylinder 403 is fixed with a conical tube 2 403b used in conjunction with the conical mouth 1 401b, the upper end surface of the powder storing cylinder 404 is provided with a conical mouth 2 404a-1, the lower end surface of the telescopic cylinder 401 is fixed with a conical tube 1 401a used in conjunction with the conical mouth 2 404a-1, and the four diagonal positions of the lower end surface of the conical tube 1 401a are provided with telescopic legs 406 folded and stored in the inner position of the recess, and the conical tube 1 401a and the conical mouth 2 404a-1 are connected. When used in combination, the telescopic cylinder 401 is used in combination with the powder storage cylinder 404, and the conical tube 403b and the conical mouth 401b are used in combination. At this time, the powder collecting cylinder 403 is used in combination with the telescopic cylinder 401, and the conical tube 403b and the conical mouth 404a-1 are used in combination. The powder collecting cylinder 403 and the powder storage cylinder 404 can be used in combination. At the same time, when the telescopic cylinder 401 is taken out between the powder collecting cylinder 403 and the powder storage cylinder 404, the telescopic support leg 406 is taken out from the internal position of the recess and retracted, so that the telescopic cylinder 401 can be erected on the ground in the room.

[0044] Further, according to Fig.10 and Fig.11 It can be seen that universal wheels 303 are fixed at the four diagonal positions of the bottom end surface of the base plate 301, push rods 302 are fixed to the upper end surfaces of the base plate 301 on both sides of the vertical frame 101, and a positioning rod 103b is fixed to the bottom of each vertical opening 103a, and each bellows 104 is respectively sleeved on the positioning rod 103b. By using the push rod 302 and the universal wheel 303, it is easy to push the movement of the entire device, and at the same time, the bellows 104 is sleeved on the positioning rod 103b, so that the positioning rod 103b limits the bellows 104, so that the internal position of the bellows 104 in the vertical opening 103a will not deviate.

[0045] It should be noted that the rotation range of the L-shaped hole 501b-1 is controlled according to the moving distance of the rack 502. At the same time, when using different powder collecting barrels 403, the L-shaped hole 501b-1 will be connected to two different ports in the three-way barrel 403a through the rotation of the ball block 501b, and the suction fan 402 and the water pump inside the water tank 201 used are controlled by an external control device and powered by an external power supply. Example

[0046] See also Figure 3 , Figure 7 and Figure 8 On the basis of Example 1, this example uses a multi-port ball tube 102 and a bellows 104 to facilitate the connection and use of the multi-port ball tube 102 and the telescopic tube 401.

[0047] Specifically, an exhaust pipe 101a connected to the air inlet of the suction fan 402 is fixed to the rear end face of the vertical frame 101, and a plurality of ball tubes 102 are connected to the end of the exhaust pipe 101a. Two installation ports 101c for bolting the powder storage cylinder 404 are provided at the bottom of the working chamber 101b. The two ports of the three-way ball cylinder 403a are respectively connected to the interior of the adjacent powder collecting cylinder 403, the air outlet of the suction fan 402 is connected to the upper port position of the three-way ball cylinder 403a located in the front, and the end of the circulation pipe 202 is connected to the upper port position of the three-way ball cylinder 403a located in the rear.

[0048] By setting up and using the above structure, the telescopic cylinder 401 is connected to the multi-port ball tube 102 through the bellows 104, so that the air inlet of the suction fan 402 is connected to the inside of the telescopic cylinder 401. Example

[0049] See also Figure 4 and Figure 6On the basis of Example 1, this embodiment uses the setting of the moving rod 502a and the circular plate 502c so that the conical piston block 502b drives the rack 502 to move.

[0050] Specifically, a curved hole 404b-1 connected to the interior of the powder storage tube 404 is provided inside the bent rod 404b, and a movable hole 404b-2 connected to the interior of the curved hole 404b-1 is provided on the upper end surface of the bent rod 404b. The conical piston block 502b slides in the movable hole 404b-2, and a movable rod 502a passing through the upper port position of the movable hole 404b-2 is fixed to the upper end surface of the conical piston block 502b. A circular plate 502c fixedly connected to the adjacent rack 502 is fixed to the upper end surface of the movable rod 502a.

[0051] By setting and using the above-mentioned structure, the water source inside the powder storage barrel 404 can flow into the curved hole 404b-1 and the movable hole 404b-2 through the use of the curved hole 404b-1 and the movable hole 404b-2, and then as the water level inside the powder storage barrel 404 rises and falls, the conical piston block 502b is pushed to move inside the movable hole 404b-2, and the movable rod 502a is pushed to move in the movable hole 404b-2, thereby pushing the circular plate 502c to drive the rack 502 to move. Example

[0052] See also Figure 3 and Figure 6 On the basis of Example 1, this embodiment can separate water and dust by using the plug plate 404d, the filter screen 404d-1 and the solenoid valve tube 404c-2 in combination.

[0053] Specifically, the bottom of the powder storage cylinder 404 is fixedly connected to a filter block 404c, and a socket 404c-1 is provided inside the filter block 404c and runs through the front position thereof. The lower end face of the filter block 404c is fixedly connected to a solenoid valve tube 404c-2 connected to the inside of the water tank 201, and a plug plate 404d is slidably plugged into the inside of each plug plate 404c-1, and a filter screen 404d-1 for powder-liquid separation is fixed in the middle of the plug plate 404d, and a pull plate 404d-2 connected to the front of the filter block 404c is fixed on the end face of the plug plate 404d.

[0054] By setting up and using the above-mentioned structure, when it is necessary to process the dust and water source inside the powder storage barrel 404, the solenoid valve tube 404c-2 is controlled to open, so that the water source inside the powder storage barrel 404 will be filtered out by the filter net 404d-1 and flow into the water tank 201 from the solenoid valve tube 404c-2. In this process, dust will accumulate on the upper end surface of the filter net 404d-1. After the water source inside the powder storage barrel 404 is processed, the pull plate 404d-2 can be moved away from the filter block 404c. At this time, the pull plate 404d-2 will pull out the filter net 404d-1 through the plug block, so that the dust on the filter net 404d-1 can be cleaned. Example

[0055] See also Figure 5 , Figure 8 and Fig.12 On the basis of Example 1, this embodiment can ensure that external air does not flow into the powder collecting barrel 403 from the position of the one-way exhaust block 405 through the coordinated use of the one-way exhaust block 405 and the rotating plate 405b.

[0056] Specifically, both end surfaces of the vertical frame 101 are provided with adjustment ports 101e connected to the interior of the working chamber 101b, and the surrounding sides of the powder collecting barrel 403 are provided with one-way exhaust blocks 405 that slide in the internal position of the adjustment ports 101e. A ventilation pipe 405a connected to the interior of the powder collecting barrel 403 is fixed to the end surface of the one-way exhaust block 405, and a rotating plate 405b is provided at the inner end surface of the one-way exhaust block 405 near the ventilation pipe 405a, and the upper end portion of the rotating plate 405b is rotatably connected to the inner wall of the one-way exhaust block 405 through an axis rod.

[0057] Through the setting and use of the above-mentioned structure, after the suction fan 402 sucks the dust into the interior of the powder collecting barrel 403, the dust will be wetted. At this time, the sucked gas will flow into the ventilation pipe 405a, and push the rotating plate 405b to rotate inside the one-way exhaust block 405, thereby flowing out from the other end of the one-way exhaust block 405. At the same time, when the rotating plate 405b is not pushed to rotate, the rotating plate 405b will block the ventilation pipe 405a, so that the external air will not flow into the powder collecting barrel 403.
