Description

Technical Field

[0001] This utility model relates to the field of indoor construction technology, and in particular to an indoor construction dust suppression device. Background Technology

[0002] During interior construction processes such as building decoration and renovation, a large amount of smoke and dust is often generated. For example, operations such as wall chiseling, floor sanding, wood cutting, and drilling of various materials all produce dust and fumes. This smoke and dust not only contains a large number of tiny particulate matter but may also contain harmful chemicals, causing serious damage to indoor air quality.

[0003] Existing dust control measures for indoor construction mainly rely on dust nets. However, due to limitations in their mesh structure and material, dust nets are unable to effectively block the spread of fine dust particles. Large amounts of fine dust can still permeate the room through the dust nets, causing dust to fill the construction site and surrounding areas. This not only affects the health of construction workers but also contaminates existing indoor facilities and furniture, increasing the difficulty and cost of subsequent cleaning. Utility Model Content

[0004] In view of this, the present invention aims to provide an indoor construction dust suppression device to reduce the spread of smoke and dust during indoor construction.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] An indoor construction dust suppression device includes:

[0007] The mounting base has a free end that can rotate about a horizontal axis;

[0008] A vacuum hood, having an intake port, is fixed to the free end to form a tilt-adjustable intake port;

[0009] The negative pressure box, connected to the vacuum hood via a hose, is capable of collecting debris sucked in by the vacuum hood.

[0010] Furthermore, the mounting base includes:

[0011] Portable seat;

[0012] The support rod is hinged to the movable seat at one end and fixed to the dust collection cover at the other end.

[0013] A locking component, connected between the support rod and the movable seat, is capable of locking the angle between the support rod and the movable seat.

[0014] Furthermore, the locking component includes:

[0015] A slide rail is provided on the movable seat in a direction perpendicular to the hinge axis of the support rod;

[0016] The slider is slidably mounted on the slide rail;

[0017] A connecting rod is hinged between the slider and the support rod;

[0018] A locking element is provided to lock the slider onto the slide rail.

[0019] Furthermore, the locking element is a bolt screwed into and passing through the slider, the bolt pressing against the slide rail to lock the slider.

[0020] Furthermore, the top of the dust hood is equipped with a first spray device.

[0021] Furthermore, a negative pressure device is provided on the top side of the negative pressure box away from the hose, and a downward-extending baffle is provided at the top of the negative pressure box. The baffle is located between the hose and the negative pressure device and forms a flow channel with the inner bottom wall of the negative pressure box.

[0022] Furthermore, the negative pressure box is equipped with a second spray device, and the spray direction of the second spray device is towards the baffle.

[0023] Furthermore, a drain pipe is provided at the bottom of the side wall of the negative pressure box, and a valve is provided on the drain pipe.

[0024] Furthermore, the bottom of the negative pressure box is equipped with casters.

[0025] Furthermore, the dust hood is a truncated square, and an intake port is provided at one end of the bottom surface of the truncated square.

[0026] Compared with the prior art, this utility model has the following advantages:

[0027] The indoor construction dust suppression equipment described in this utility model features a negative pressure box that, through connection to the dust collection hood, creates negative pressure within the hood, enabling it to absorb smoke and dust. This provides a better dust suppression effect compared to traditional dust nets. Furthermore, the adjustable dust collection hood allows for the absorption of smoke and dust generated at different heights, further enhancing the dust suppression effect. The flexible hose allows the dust collection hood to be moved freely without affecting dust collection.

[0028] Secondly, by setting up a support rod and locking assembly, the dust hood can rotate with the support rod, achieving tilt adjustment. The slider slides stably on the slide rail. When the locking component locks the slider onto the slide rail, the support rod, connecting rod, and slide rail form a triangle, firmly fixing the support rod in place. Using a bolt as the locking component allows for easy tightening and loosening, and since bolts are standard parts, their availability is low.

[0029] Furthermore, the first spray device can spray water mist onto the area facing the dust collection hood, effectively reducing dust. The water mist adheres to the dust, allowing for better absorption. The baffles prevent particles entering the negative pressure chamber from the hose from impacting and falling, thus preventing them from entering the negative pressure device with the airflow. The second spray device sprays water into the negative pressure chamber, further reducing the amount of smoke and dust drawn in. Simultaneously, the second spray device cleans the baffles, and the water flowing into the bottom of the negative pressure chamber also helps absorb smoke and dust, improving the dust suppression effect of the indoor construction dust suppression equipment.

[0030] In addition, a drain pipe is installed on the negative pressure box to quickly discharge wastewater. Casters are installed under the negative pressure box for easy movement, improving usability. The dust collection hood is designed as a truncated pyramid shape, providing better dust collection performance. Attached Figure Description

[0049] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] This embodiment relates to an indoor construction dust suppression device to reduce the spread of smoke and dust during indoor construction, thereby improving the air quality during indoor construction.

[0051] In terms of overall structure, refer to Figure 1 and Figure 2 As shown, an indoor construction dust suppression device according to this embodiment includes a mounting base 1, a dust collection hood 2, and a negative pressure box 3. The mounting base 1 has a free end that can rotate about a horizontal axis. The dust collection hood 2 has an intake port 201, which is fixed to the free end to enable the intake port 201 to be tilt-adjustable. The negative pressure box 3 is connected to the dust collection hood 2 via a flexible hose and is capable of collecting debris sucked in by the dust collection hood 2.

[0052] As configured above, in this embodiment of the indoor construction dust suppression equipment, the negative pressure box 3, connected to the dust extraction hood 2, can create negative pressure within the hood 2, allowing it to absorb smoke and dust effectively. This provides better dust suppression compared to traditional dust nets. By providing an adjustable dust extraction hood 2, it can absorb smoke and dust generated at different heights, further enhancing the dust suppression effect of the indoor construction dust suppression equipment. The flexible hose allows the dust extraction hood 2 to be moved freely without affecting dust extraction.

[0053] Based on the above overview, specifically, the indoor construction dust suppression equipment of this embodiment can absorb dust at various heights. For example, during cement mixing or demolition of the base, the dust extraction hood 2 can be oriented towards a lower position; during wall grooving or chiseling, the dust extraction hood 2 can be oriented towards a higher position to better absorb dust. The bottom of the negative pressure box 3 is equipped with casters 9, which facilitates the movement of the negative pressure box 3 and improves ease of use.

[0054] Regarding the specific structure of the mounting base 1 in this embodiment, the mounting base 1 includes a movable base 101, a support rod 102, and a locking assembly 103. One end of the support rod 102 is hinged to the movable base 101, and the other end is fixed to the dust cover 2. The locking assembly 103 is connected between the support rod 102 and the movable base 101, and can lock the angle between the support rod 102 and the movable base 101. By setting the support rod 102 and the locking assembly 103, the dust cover 2 can rotate with the support rod 102, realizing the tilt adjustment of the dust cover 2.

[0055] Preferably, in this embodiment, two support rods 102 are symmetrically arranged on the movable base 101, and each support rod 102 corresponds to a set of locking components 103, which can more stably support the dust hood 2. The movable base 101 is U-shaped, with its opening facing the suction direction of the dust hood 2, which allows the dust hood 2 to also absorb some of the smoke and dust below the movable base 101. The bottom end of the movable base 101 is provided with casters 9 to realize the movable function of the movable base 101.

[0056] Furthermore, the locking assembly 103 includes a slide rail 1031, a slider 1032, a connecting rod 1033, and a locking member 1034. The slide rail 1031 is disposed on the movable seat 101 in a direction perpendicular to the hinge axis of the support rod 102. The slider 1032 is slidably disposed on the slide rail 1031. The connecting rod 1033 is hinged between the slider 1032 and the support rod 102. The locking member 1034 can lock the slider 1032 onto the slide rail 1031. The slider 1032 slides relatively stably on the slide rail 1031. When the locking member 1034 locks the slider 1032 onto the slide rail 1031, the support rod 102, the connecting rod 1033, and the slide rail 1031 form a triangle, thus firmly fixing the support rod 102.

[0057] Specifically, the locking element 1034 is a bolt screwed into and passing through the slider 1032. The bolt abuts against the slide rail 1031 to lock the slider 1032. Using a bolt as the locking element 1034 allows for easy tightening and loosening, and bolts are standard parts, resulting in low acquisition costs. Of course, the locking element 1034 could also be a device such as a pin or clamp, which would only lock the slider 1032 at different angles of the support rod 102.

[0058] Secondly, to further enhance the dust suppression function of the indoor construction dust suppression equipment, a first spray device 4 is installed at the top of the dust hood 2. The first spray device 4 can spray water mist onto the area facing the dust hood 2, thereby reducing dust. The water mist adheres to the dust and is then better absorbed. Specifically, the first spray device 4 includes two nozzles, which are fixed to the top of the dust hood 2. The two nozzles are connected to a common pipe, which is connected to a pressurized water source such as tap water.

[0059] Furthermore, regarding the specific working principle of the negative pressure box 3, in this embodiment, a negative pressure device 6 is provided on the top side of the negative pressure box 3 away from the hose. A downward-extending baffle 301 is provided at the top of the negative pressure box 3. The baffle 301 is positioned between the hose and the negative pressure device 6, forming a flow channel 302 between the baffle 3 and the inner bottom wall of the negative pressure box 3. The negative pressure device 6 can generate negative pressure inside the negative pressure box 3. A filter screen is provided at the connection point with the negative pressure box 3 to block some dust particles from entering the negative pressure device 6. The hose is connected to the top of one side of the negative pressure box 3, and the baffle 301 is provided so that the debris particles entering the negative pressure box 3 from the hose can hit the baffle 301 and fall down, stored at the bottom of the negative pressure box 3, and are not easily carried by the airflow into the negative pressure device 6.

[0060] Meanwhile, a second spray device 5 is installed inside the negative pressure box 3, with the spray direction of the second spray device 5 facing the baffle 301. The second spray device 5 can spray the inside of the negative pressure box 3, further reducing the smoke and dust sucked into the negative pressure device 6 and extending the service life of the negative pressure device 6. The second spray device 5 can also clean the baffle 301, washing away the smoke and dust on the baffle 301 in a timely manner. The water sprayed by the second spray device 5, after flowing into the bottom of the negative pressure box 3, can also adsorb smoke and dust, improving the dust suppression effect of the indoor construction dust suppression equipment.

[0061] Furthermore, a drain pipe 7 is provided at the bottom of the side wall of the negative pressure tank 3, and a valve 8 is installed on the drain pipe 7. The drain pipe 7 on the negative pressure tank 3 allows for the rapid discharge of wastewater from the tank. In this example, the drain pipe 7 is located at the bottom end of the side wall of the negative pressure tank 3 away from the hose and extends in a direction away from the negative pressure tank 3. A manual butterfly valve is used in this embodiment to control the flow of liquid within the drain pipe 7.

[0062] In addition, the dust hood 2 is a truncated pyramid, and a suction port 201 is provided at one end of the bottom surface of the truncated pyramid. Setting the dust hood 2 as a truncated pyramid can increase the suction range of the dust hood 2 and have a better suction effect.

[0063] In this embodiment of the indoor construction dust suppression equipment, the negative pressure box 3, connected to the dust extraction hood 2, can create negative pressure within the hood 2, allowing it to absorb smoke and dust effectively. This results in better dust suppression compared to traditional dust nets. The inclusion of a first spray device 4 and a second spray device 5 further enhances the dust suppression effect. By providing an adjustable dust extraction hood 2, smoke and dust can be absorbed at different heights, further improving the dust suppression performance of the indoor construction dust suppression equipment.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
