Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, and in particular to a spray dust suppression device used in conjunction with an excavator. Background Technology

[0002] Excavation, site leveling, and garbage removal during building construction, as well as trench excavation and backfilling in municipal construction, landscaping clearing, roadbed leveling, and soil mixing, generate significant amounts of dust. With increasing emphasis on environmental protection and stricter penalties for dust pollution from relevant regulatory departments across the country, more and more regions are requiring "one machine, one fog cannon." Fog cannons are expensive, require dedicated personnel for operation, are limited by their own spray range, and their routes need to be pre-leveled, making them unsuitable for complex and varied building and municipal construction sites. Therefore, there is an urgent need for a low-cost, effective dust suppression spray device that meets environmental requirements and can adapt to more diverse terrain conditions at building and municipal construction sites.

[0003] The applicant discovered through a search that a Chinese patent discloses "A Dust Suppression Device for Excavators," with publication (announcement) number "CN 207153341 U." This patent mainly includes a compression device, a flexible pressure-bearing pipe, a water tank, and a U-shaped support spray device. The compressor power is provided by the excavator's generator system or battery, and the compressor's water inlet pipe is connected to the rear water tank. This utility model patent has a simple and clear structure, is easy to install, and is not affected by external factors other than the excavator. It has a good effect on dust suppression at construction sites and effectively reduces the cost of manual water spraying for dust suppression. However, the existing technology has limitations in dust suppression for dust generated by excavators during operation. Dust is easily dispersed, and dust in the air can spread over a wide area. Single water spraying for dust suppression has limitations. Therefore, we propose a spray dust suppression device that is used in conjunction with an excavator. Utility Model Content

[0004] The purpose of this utility model is to provide a spray dust suppression device for use with excavators, so as to solve the problem mentioned in the background art that the existing technology has limitations in dust suppression when excavators are working. Dust is easily dispersed in the air and the area is relatively wide, so single water spraying has limitations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray dust suppression device for use with an excavator, comprising an excavator body, wherein a dust suppression mechanism and an adsorption dust removal mechanism are respectively provided on the rear right side and the upper end of the excavator body; the dust suppression mechanism includes a stabilizing plate, the stabilizing plate is connected to a water inlet pipe through a water storage tank, the water inlet pipe is connected to a water outlet pipe through a water pump, the water outlet pipe is connected to a branch pipe and a water mist nozzle through a water storage pipe; the adsorption dust removal mechanism includes a liquid storage tank, the liquid storage tank is connected to a metering pump through a plastic conduit, the metering pump is connected to a water collection tank through a connecting pipe, and the water collection tank is connected to an atomizing nozzle through an elbow pipe.

[0006] As a preferred embodiment, the stabilizing plate is fixedly installed on the rear side of the excavator body, the water tank is fixedly installed on the surface of the stabilizing plate, one end of the water inlet pipe is fixedly connected to the water tank and extends into it, while the other end is fixedly connected to the input end of the water pump, the water outlet pipe is fixedly installed at the output end of the water pump, and two sets of pipe clamps are fixedly installed on the surface of the boom of the excavator body, with the water outlet pipe fitted inside the two sets of pipe clamps.

[0007] As a preferred embodiment, the water pump is fixedly installed on the right rear end surface of the excavator body, the water tank has an inlet on one side of its surface, the inlet pipe has a filter inside the end near the water tank, and the water storage pipe is fixedly installed at the end of the outlet pipe away from the water tank.

[0008] As a preferred embodiment, multiple sets of branch pipes and water mist nozzles are provided and distributed at equal intervals. One end of each set of branch pipes is fixedly installed on the side of the water storage pipe and is inclined. The end of each set of branch pipes away from the water storage pipe is fixedly connected to the multiple sets of water mist nozzles.

[0009] As a preferred embodiment, the liquid storage tank is fixedly installed on the upper right side surface of the excavator body. One end of the plastic conduit is fixedly connected to the liquid storage tank and extends into it. The end of the plastic conduit away from the liquid storage tank is fixedly connected to the input end of the metering pump. The connecting pipe is fixedly installed at the output end of the metering pump. Both the metering pump and the water collection tank are fixedly installed on the top of the excavator body. The end of the connecting pipe away from the metering pump is fixedly connected to the water collection tank, and the connecting pipe extends into the interior of the water collection tank.

[0010] As a preferred embodiment, the elbow pipe and the atomizing nozzle are provided in multiple sets and are distributed at equal distances. One end of each set of elbow pipes is fixedly connected to the water collection tank and extends into the interior of the water collection tank, while the other end is fixedly connected to each set of atomizing nozzles. A sealing gasket is fixedly installed at the connection between the plastic conduit and the liquid storage tank.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting up a dust suppression mechanism, during excavator operation, the water pump is started, and water in the storage tank is drawn out through the inlet pipe under the suction of the water pump. The water then flows through the water pump, outlet pipe, and storage pipe in sequence, and finally reaches the water mist nozzle through multiple branch pipes. It is sprayed out from the nozzle in a mist form. The water mist nozzle has a unique design that can atomize water into extremely small water droplets. Under the combined action of gravity and air resistance, these tiny water droplets slowly spread in the excavator's working area. They collide and adsorb with the dust particles floating in the air, causing the weight of the dust particles to gradually increase and then settle to the ground, thus achieving the purpose of dust suppression. The water mist nozzle is installed at the position of the excavator's boom, which can spray dust at close range to the excavation work point, perfectly covering the working range of the boom and greatly enhancing practicality.

[0013] 2. By setting up an adsorption dust removal mechanism, the metering pump starts working when the dust suppression mechanism is running. It extracts the dry fog dust suppressant from the storage tank. During this process, the dry fog dust suppressant flows along the plastic conduit, then passes through the connecting pipe and the water collection tank in sequence. After passing through the elbow pipe, it finally reaches the atomizing nozzle. The dry fog dust suppressant is a special chemical reagent. Under the action of the adsorption dust removal mechanism, it is atomized into a large number of tiny droplets at the atomizing nozzle and sprayed into the air. These tiny droplets have adsorption capacity. They can accurately capture the dust particles floating in the air. When the dust particles meet the droplets, the two combine with each other. The dust particles gradually agglomerate and become larger, increasing in weight. Under the action of gravity, they are easier to settle, effectively suppressing the dust raised by the excavator during digging and preventing it from scattering randomly, thus building a green dust barrier for the working environment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] Please see the appendix Figure 1 - Appendix Figure 2 and appendix Figure 4A dust suppression spray device for use with an excavator includes an excavator body 1. A dust suppression mechanism 2 and an adsorption dust removal mechanism 3 are respectively provided on the rear right side and upper end of the excavator body 1. The dust suppression mechanism 2 includes a stabilizing plate 201, which is connected to an inlet pipe 203 via a water storage tank 202. The inlet pipe 203 is connected to an outlet pipe 205 via a water pump 204. The outlet pipe 205 is connected to a branch pipe 208 and a water mist nozzle 209 via a water storage pipe 207. The adsorption dust removal mechanism 3 includes a liquid storage tank 301, which is connected to a metering pump 303 via a plastic conduit 302. The metering pump 303 is connected to a water collection tank 305 via a connecting pipe 304. The water collection tank 305 is connected to an atomizing nozzle 307 via an elbow pipe 306. The stabilizing plate 201 is fixedly installed on the rear rear side of the excavator body 1, and the water storage tank 202 is fixedly installed on the surface of the stabilizing plate 201. One end of the inlet pipe 203 is connected to... The water storage tank 202 is fixedly connected and extends into its interior, while its other end is fixedly connected to the input end of the water pump 204. The water outlet pipe 205 is fixedly installed at the output end of the water pump 204. Two sets of pipe clamps 206 are fixedly installed on the surface of the boom of the excavator body 1. The water outlet pipe 205 is fitted inside the two sets of pipe clamps 206. The water pump 204 is fixedly installed on the right rear end surface of the excavator body 1. A water inlet 210 is provided on one side of the surface of the water storage tank 202. A filter 211 is provided inside the end of the water inlet pipe 203 near the water storage tank 202. The water storage pipe 207 is fixedly installed at the end of the water outlet pipe 205 away from the water storage tank 202. Multiple sets of branch pipes 208 and water mist nozzles 209 are provided and are distributed at equal distances. One end of each set of branch pipes 208 is fixedly installed on the side of the water storage pipe 207 and is inclined. The ends of the multiple sets of branch pipes 208 away from the water storage pipe 207 are fixedly connected to the multiple sets of water mist nozzles 209.

[0022] The water storage pipe 207 is fixed on the boom of the excavator body 1 and moves up and down synchronously with the boom. The water outlet pipe 205 is a flexible pressure-bearing pipe that can be reversed and stretched at will, and has extensibility without affecting its drainage effect. The filter 211 prevents dirt and residue in the water storage tank 202 from being discharged and clogging the outlet of the water mist nozzle 209.

[0023] Specifically, during operation, the excavator body 1 starts the water pump 204, drawing water from the water tank 202 through the inlet pipe 203. The water then passes through the water pump 204, the outlet pipe 205, and the storage pipe 207, and is finally sprayed out through multiple branch pipes 208 and water mist nozzles 209. The water mist nozzles 209 atomize the water into tiny droplets, forming a spray. These tiny droplets, under the influence of gravity and air resistance, diffuse in the excavator's working area, colliding with and adsorbing dust particles in the air, causing the dust particles to increase in weight and settle, thereby achieving the purpose of dust suppression. The water mist nozzles 209 are installed at the boom for close-range spraying to suppress dust at the excavation work point, covering the boom's working area, and have strong practicality.

[0024] Example 2:

[0025] Please see the appendix Figure 1 - Appendix Figure 3 Furthermore, based on Embodiment 1, the following configuration is further provided: the liquid storage tank 301 is fixedly installed on the upper right side surface of the excavator body 1; one end of the plastic conduit 302 is fixedly connected to the liquid storage tank 301 and extends into it; the end of the plastic conduit 302 away from the liquid storage tank 301 is fixedly connected to the input end of the metering pump 303; the connecting pipe 304 is fixedly installed at the output end of the metering pump 303; both the metering pump 303 and the water collection tank 305 are fixedly installed on the top of the excavator body 1; and the connecting pipe 304... One end away from the metering pump 303 is fixedly connected to the water collection tank 305, and the connecting pipe 304 extends into the interior of the water collection tank 305. Multiple sets of elbow pipes 306 and atomizing nozzles 307 are provided and are distributed at equal distances. One end of each set of elbow pipes 306 is fixedly connected to the water collection tank 305 and extends into the interior of the water collection tank 305, while the other end is fixedly connected to multiple sets of atomizing nozzles 307. A sealing gasket 308 is fixedly installed at the connection between the plastic conduit 302 and the liquid storage tank 301.

[0026] Dry fog dust suppressant is a special chemical reagent that is atomized by the adsorption dust removal mechanism 3 and sprayed into the air to form a large number of tiny droplets. These droplets can adsorb dust particles in the air, causing the dust particles to agglomerate and become larger, thus making them easier to settle. Compared with ordinary water spray dust removal, dry fog dust suppressant requires less dosage and has more advantages in some water-scarce working environments or in material excavation operations that are sensitive to humidity. The metering pump 303 is a key component, which can accurately control the output of dry fog dust suppressant. Unlike ordinary pumps, the metering pump 303 can accurately deliver the dust suppressant to the atomizing nozzle 307 according to the preset flow and pressure parameters. This is because the effect of dry fog dust suppressant is closely related to the spray volume and spray concentration. Too much or too little may affect the dust removal effect.

[0027] Specifically, while the dust suppression mechanism 2 is working, the metering pump 303 draws the dry fog dust suppressant from the storage tank 301 through the plastic conduit 302, and then passes it through the connecting pipe 304, the water collection tank 305, and the elbow pipe 306 in sequence. Finally, the dry fog dust suppressant is sprayed out through the atomizing nozzle 307. The dry fog dust suppressant is a special chemical reagent. After being atomized by the adsorption dust removal mechanism 3, it is sprayed into the air to form a large number of tiny droplets. These droplets can adsorb dust particles in the air, causing the dust particles to agglomerate and become larger, thus making them easier to settle. This is used to suppress the dust raised by the excavator during the digging process and prevent the dust from spreading everywhere.

[0028] Working principle: This utility model is a spray dust suppression device used in conjunction with an excavator. First, before the excavator body 1 starts working, the water tank 202 and the liquid tank 301 are filled with water and dry fog dust suppressant, respectively. During operation, the water pump 204 is started, and water is drawn from the water tank 202 through the inlet pipe 203. The water passes through the water pump 204, the outlet pipe 205, and the storage pipe 207, and is finally sprayed out through multiple branch pipes 208 and water mist nozzles 209. The water mist nozzles 209 atomize the water into tiny water droplets, forming a spray. These tiny water droplets diffuse in the excavator's working area under the action of gravity and air resistance, colliding with and being absorbed by dust particles in the air. The process involves increasing the weight of dust particles, causing them to settle and thus achieving dust suppression. Simultaneously, the metering pump 303 extracts the dry fog dust suppressant from the storage tank 301 through the plastic conduit 302, passing it sequentially through the connecting pipe 304, the water collection tank 305, and the elbow pipe 306. The dry fog dust suppressant is then sprayed out through the atomizing nozzle 307. This dry fog dust suppressant is a special chemical reagent that is atomized by the adsorption and dust removal mechanism 3 and sprayed into the air, forming numerous tiny droplets. These droplets adsorb dust particles in the air, causing them to agglomerate and become larger, making them easier to settle. This process suppresses dust raised during excavation. The entire process is then complete.
