Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to a skid-mounted integrated automatic wet dust collector for sludge removal. Background Technology

[0002] With the rapid development of industrial robot technology, robotic polishing equipment has been widely used in metal processing, automotive parts manufacturing, and precision instrument production. During the polishing process, the friction between the high-speed rotating abrasive and the workpiece generates a large amount of metal dust. This dust is characterized by its small particle size, strong diffusion, and easy accumulation. Although most polishing equipment currently uses a closed operating environment, dust control is still necessary. Otherwise, dust intrusion into the robot's joint transmission components can lead to a decrease in motion accuracy. Dust that is not removed in time will adhere to the workpiece surface, causing secondary pollution and reducing product smoothness. Furthermore, dust accumulation in a confined space also poses a risk of explosion. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a skid-mounted integrated automatic wet dust collector to solve the technical problems in the existing technology where the failure to deal with dust in the working environment of robotic polishing equipment in a timely manner can easily lead to the decline of robot motion accuracy, contamination of workpiece surface, and safety hazards.

[0004] To solve the above-mentioned technical problems, this utility model provides a skid-mounted integrated automatic wet dust collector, comprising:

[0005] Base frame;

[0006] The cylinder is connected to the base frame and is equipped with an air inlet and a mud outlet. Both the air inlet and the mud outlet are higher than the liquid level inside the cylinder.

[0007] Negative pressure fan, connected to the top of the cylinder;

[0008] The hydrocyclone is located inside the cylinder and between the negative pressure fan and the air inlet;

[0009] The silencer filter box has a first air outlet on its cylindrical body. The first air outlet is located between the negative pressure fan and the cyclone separator in the height direction. The silencer filter box is connected to the first air outlet and has a second air outlet. The silencer filter box is equipped with a silencer component and a filter component.

[0010] A sludge scraper is installed inside the cylinder and is used to discharge the sludge inside the cylinder from the sludge outlet.

[0011] With the above structure, the skid-mounted integrated automatic wet dust collector of this utility model has the following advantages: A negative pressure fan generates negative pressure, drawing in dust-laden gas generated by the robotic polishing equipment through the inlet. The dust-laden gas reacts with water in the cylinder using a Venturi effect, stimulating the liquid surface and mixing the dust with the water. The water-laden gas rises and passes through a hydrocyclone for gas-liquid separation, while the liquid falls back into the cylinder. The gas then enters a silencer filter box for silencing and secondary filtration before being directly discharged into the working environment of the robotic polishing equipment. This avoids dust causing a decrease in the robot's motion accuracy, contaminating the workpiece surface, and reducing safety hazards. The dust mixed in the water settles and is scraped out of the cylinder by a scraper. This utility model adopts a skid-mounted integrated design, with each component directly or indirectly mounted on the base frame, reducing the footprint and meeting the requirements of the working environment of the robotic polishing equipment.

[0012] As an improvement, the cylinder includes a dust collector and a sludge scraping pipe. The bottom end of the dust collector and the bottom end of the sludge scraping pipe are connected to each other. The sludge scraping pipe is set at an angle upward. The air inlet, negative pressure fan, cyclone separator, and first air outlet are all located in the dust collector, and the sludge outlet is located in the sludge scraping pipe. The sludge scraper is set along the length of the sludge scraping pipe. With this structure, the sludge scraping pipe, which is set at an angle upward, can directly scrape the sludge settled at the bottom of the cylinder to the sludge outlet by the sludge scraper.

[0013] As an improvement, the bottom of the dust collector cylinder and the bottom of the sludge scraping pipe form a conical structure, and a drain valve is connected to the bottom of the conical structure. With this structure, the conical structure makes it easy for water and sludge to accumulate at the bottom of the cylinder, which facilitates the discharge of sludge and water.

[0014] As an improvement, the silencer filter box includes a first chamber and a second chamber, which are connected by an internal channel. The silencer filter box is provided with a second air inlet that connects the first air outlet and the first chamber. The second air outlet connects to the second chamber. The silencer assembly is located in the first chamber, and the filter assembly is located in the second chamber. With this structure, the gas entering the silencer filter box is first silenced by the silencer assembly in the first chamber, and then the gas undergoes secondary filtration by the filter assembly in the second chamber.

[0015] As an improvement, the noise reduction assembly includes noise-reducing cotton disposed on the inner wall of the first cavity.

[0016] As an improvement, the filtration assembly includes a filter bag disposed within the second chamber.

[0017] As an improvement, the silencer filter box is positioned higher than the liquid level inside the cylinder, and the inner cavity of the silencer filter box is connected to the inner cavity of the cylinder via a drain pipe. With this structure, a small amount of moisture contained in the gas in the silencer filter box can be drained back into the cylinder through the drain pipe.

[0018] As an improvement, the cylinder is connected to a water replenishment device, which includes a water replenishment tank, a liquid level sensor, and an inlet valve. The water replenishment tank is connected to the cylinder, and both the liquid level sensor and the inlet valve are connected to the water replenishment tank. The inlet valve and the liquid level sensor are electrically connected. With this structure, the liquid level sensor detects the liquid level. When the water level in the cylinder decreases, the inlet valve opens to automatically replenish water, so that the liquid level in the cylinder is always maintained at a certain height to achieve the best dust removal effect.

[0019] As an improvement, a drain valve is connected to the bottom of the water tank; with this structure, if a malfunction or other situation causes the liquid level to be too high, the water can be drained manually through the drain valve.

[0020] As an improvement, the base frame is equipped with several forks, and the top of the cylinder is equipped with several lifting lugs; this structure facilitates transportation and installation. Attached Figure Description

Detailed Implementation

[0027] The following is a detailed description of a skid-mounted integrated automatic wet dust collector according to the present invention, with reference to the accompanying drawings.

[0028] like Figures 1 to 5As shown, a skid-mounted integrated automatic wet dust collector includes a base frame 1, a cylinder 2, a negative pressure fan 5, a cyclone separator 6, a silencer filter box 7, and a sludge scraper 10. The cylinder 2 is connected to the base frame 1 and has an air inlet 3 and a sludge outlet 4. Both the air inlet 3 and the sludge outlet 4 are higher than the liquid level inside the cylinder 2. The cylinder 2 includes a dust collection cylinder 21 and a sludge scraping pipe 22. The bottom end of the dust collection cylinder 21 is connected to the bottom end of the sludge scraping pipe 22. The sludge scraping pipe 22 is angled upwards. The air inlet 3 is located on the dust collection cylinder 21 and extends outwards to form an upward-facing pipe. Figure 2 As shown. The sludge scraper 10 is located inside the cylinder 2 and is used to discharge the sludge inside the cylinder 2 from the sludge outlet 4.

[0029] like Figure 1 As shown, the mud outlet 4 is located in the sludge scraping pipe 22, extending downwards to form a pipe with the outlet facing downwards. The sludge scraper 10 is arranged along the length of the sludge scraping pipe 22, with its lower end located at the bottom of the cylinder 2 and its upper end higher than the mud outlet 4. The sludge scraper 10 is driven by a motor, which drives the scraper blades to scrape the sludge along the inner wall of the sludge scraping pipe 22 to the mud outlet 4. The specific structure and working principle of the sludge scraper 10 are existing technologies and will not be described in detail here. Figure 3 As shown, an inspection cover 29 is provided on the side wall of the sludge scraper pipe 22 to facilitate the maintenance of the sludge scraper 10.

[0030] In addition, such as Figure 1 and Figure 2 As shown, the bottom end of the dust collector 21 and the bottom end of the sludge scraping pipe 22 form a conical structure, and the bottom end of the conical structure is connected to a drain valve 11.

[0031] like Figure 1 As shown, the negative pressure fan 5 is connected to the top of the cylinder 2, specifically the top of the dust collector cylinder 21. The cyclone separator 6 is located inside the cylinder 2 and between the negative pressure fan 5 and the air inlet 3, specifically inside the dust collector cylinder 21. The cylinder 2 has a first air outlet 8, which is located between the negative pressure fan 5 and the cyclone separator 6 in the height direction. Similarly, the first air outlet 8 is also located on the dust collector cylinder 21. Specifically, in this embodiment, the top of the dust collector cylinder 21 is open and connected to a pipe. The negative pressure fan 5 is connected to the top of the pipe. The pipe communicates with the dust collector cylinder 21, and the first air outlet 8 is formed at the right end of the pipe. The airflow direction is as follows: Figure 1 The arrow shown.

[0032] like Figure 1 As shown, the silencer filter box 7 is connected to the aforementioned pipe, the silencer filter box 7 is connected to the first air outlet 8 and has a second air outlet 9, and the silencer filter box 7 is equipped with a silencer component and a filter component.

[0033] like Figure 1 and Figure 5As shown, the silencing filter box 7 includes a first cavity 71 and a second cavity 72. The first cavity 71 and the second cavity 72 are connected by an internal channel of the silencing filter box 7. The silencing filter box 7 is provided with a second air inlet 12 that connects the first air outlet 8 and the first cavity 71. The second air outlet 9 connects to the second cavity 72. The silencing component is located in the first cavity 71, and the filter component is located in the second cavity 72.

[0034] Specifically, refer to Figure 5 , Figure 5 The left side is the first cavity 71, and the right side is the second cavity 72. The second air inlet 12 is located on the side wall of the silencer filter box 7 corresponding to the first cavity 71. (See reference...) Figure 1 Continue to refer to Figure 1 The noise reduction assembly includes noise reduction cotton 13 disposed on the inner wall of the first cavity 71, and the noise reduction cotton 13 encloses to form a ring-shaped closed structure (this structure can be referred to). Figure 5 This creates an airflow channel within the inner ring of the sound-absorbing cotton 13. Airflow enters the airflow channel from the second air inlet 12, and then flows downwards after exiting at the end of the airflow channel. (Reference...) Figure 5 The filter assembly includes a filter bag 14 disposed in the second cavity 72. After the airflow flows out of the airflow channel, it passes through the filter bag 14 for secondary filtration to the right and is discharged from the top of the second air outlet 9 at the top of the silencer filter box 7.

[0035] like Figure 1 As shown, the silencer filter box 7 is higher than the liquid level inside the cylinder 2, and the inner cavity of the silencer filter box 7 is connected to the inner cavity of the cylinder 2 via a drain pipe 15; specifically, one end of the drain pipe 15 is provided with two branch pipes, which are respectively connected to the first cavity 71 and the second cavity 72. In addition, the silencer filter box 7 is also provided with an inspection door 28 for replacing the filter bag 14. Figure 2 As shown, the bottom of the silencing filter box 7 is connected to the sludge scraping pipe 22. A differential pressure gauge 25 is connected to the silencing filter box 7 to determine whether the filter bag 14 is clogged, so that it can be replaced in time.

[0036] like Figure 2 and Figure 4 As shown, the cylinder 2 is connected to a water replenishment device 16, which includes a water replenishment tank 161, a liquid level sensor 162, and an inlet valve 163. The water replenishment tank 161 is connected to the cylinder 2. Specifically, an opening 20 is provided on the side wall of the dust collector cylinder 21, which directly communicates with the inner cavity of the water replenishment tank 161. The liquid level sensor 162 and the inlet valve 163 are both connected to the water replenishment tank 161, and the inlet valve 163 and the liquid level sensor 162 are electrically connected. A drain valve 17 is connected to the bottom of the water replenishment tank 161.

Figure 2As shown, the electrical control box 24 is placed in the space between the dust collector 21, the sludge scraping pipe 22 and the silencer filter box 7, making the overall structure more compact. The outer side of the cylinder 2 is connected to the cable tray 26.

[0037] like Figure 4 As shown, an observation door 27 is also provided at the top of the water tank 161 for cleaning and inspection. An inner partition 23 is detachably connected to the side wall of the dust collector 21 corresponding to the water tank 161 to prevent floating objects from entering the water tank 161 and accumulating.

[0038] like Figure 2 As shown, the base frame 1 is provided with several forks 18, and the top of the cylinder 2 is provided with several lifting lugs 19.

[0039] This invention utilizes a negative pressure fan 5 to generate negative pressure, drawing in dust-laden gas from the robotic polishing equipment through the air inlet 3. The dust-laden gas reacts with the water inside the cylinder 2 via a Venturi effect, stimulating the liquid surface and mixing the dust with the water. The water-laden gas rises and passes through a hydrocyclone 6 for gas-liquid separation, while the liquid falls back into the cylinder 2. The gas then enters a silencer filter box 7 for silencing and secondary filtration, allowing it to be directly discharged into the working environment of the robotic polishing equipment. This prevents dust from causing a decrease in the robot's motion accuracy, contaminating the workpiece surface, and reducing safety hazards. After settling, the dust mixed in the water is scraped out of the cylinder 2 by a scraper 10.

[0040] This utility model adopts a skid-mounted integrated design, with each component directly or indirectly mounted on the base frame 1. It has a compact structure, small footprint, and convenient installation, meeting the requirements of the working environment of robotic polishing equipment.

However, the present invention is not limited to the above-described embodiment. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
