Description

Technical Field

[0001] The invention relates to sludge and sewage treatment, in particular to a device for treating sludge from wastewater from cutting of marble slabs. Background Art

[0002] Marble is popular in the market for its unique texture and beautiful texture. However, in the marble processing, a large amount of wastewater sludge will be generated in the cutting process. If these wastewater sludges are discharged directly without proper treatment, they will cause serious harm to the environment. Pollutants such as suspended matter, stone powder and possible heavy metals contained in the wastewater will cause water turbidity and deterioration of water quality, destroy the balance of the aquatic ecosystem, and affect the normal use function of the surrounding water bodies. Sludge accumulation not only occupies a large amount of land resources, but may also cause secondary pollution due to rain erosion and other reasons, and have a negative impact on soil structure and vegetation growth. It is worth noting that marble wastewater sludge is not entirely waste, and it contains a certain amount of fine powdered materials. These materials can be recycled and reused after a series of treatments such as scientific pressing, dehydration, and drying. For example, it can be used as a raw material for the production of building ceramics, artificial stone and other products, or used to make fillers, etc., so as to achieve the recycling of resources and create additional economic value; At present, although there are some methods and devices on the market for marble wastewater sludge treatment, they generally have many shortcomings. Some treatment methods only stay at the primary stage of simple sedimentation and filtration, and are unable to deeply separate and extract the useful components, resulting in serious waste of resources. Although some more complex treatment equipment can achieve higher treatment efficiency in theory, due to their complex structure, high maintenance cost, and extremely high professional requirements for operators, they face many difficulties in practical applications and are difficult to be widely promoted in the industry; In summary, the development of an efficient, environmentally friendly and economically feasible marble slab cutting wastewater sludge treatment device is of great significance for solving the current environmental and resource problems faced by the marble processing industry and promoting the sustainable development of the industry.

DETAILED DESCRIPTION

[0017] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example: Figure 1-Figure 7As shown, a marble slab cutting wastewater sludge treatment device is provided, including a support plate 1, the upper surface of the support plate 1 is fixedly connected to a conveying device 2, the upper surface of the support plate 1 is symmetrically fixedly connected to a support column 3 located on the outer side of the conveying device 2, the inner side walls of the support column 3 are commonly fixedly connected to a sewage treatment chamber 4, the upper surface of the sewage treatment chamber 4 is provided with an arc-shaped water storage trough 5, and the interior of the arc-shaped water storage trough 5 is symmetrically provided with a discharge port 6, the outer side wall of the sewage treatment chamber 4 is symmetrically fixedly connected to a feed chamber 7, and the feed chamber 7 is fixedly connected to the discharge port 6, the upper surface of the sewage treatment chamber 4 is fixedly connected to a push chamber 8, the inner rear surface of the push chamber 8 is rotatably connected to a rotating rod 9, the outer side wall of the rotating rod 9 is fixedly connected to a transmission tooth 10, the front end of the rotating rod 9 passes through the front end of the push chamber 8, the outer side wall of the rotating rod 9 is located on the outer side of the push chamber 8 and is fixedly connected to an elastic rod 11, and the bottom end of the elastic rod 11 is fixedly connected A push plate 12 is connected, and a leaking hole 13 is fixedly connected inside the push plate 12. A telescopic chamber 14 is fixedly connected to the right side of the upper surface of the sewage treatment chamber 4. A sliding plate 15 is slidably connected inside the telescopic chamber 14. A transverse plate 16 is fixedly connected to the left side of the sliding plate 15. A rack 17 is fixedly connected to the upper surface of the transverse plate 16. Slides 18 are symmetrically provided inside the push chamber 8. The outer wall of the transverse plate 16 is slidably connected to the inner walls of the two slides 18. The rack 17 is meshed with the transmission gear 10. An intermittent air outlet chamber 19 is fixedly connected to the front surface of the sewage treatment chamber 4. The intermittent air outlet chamber 19 is fixedly connected to the telescopic chamber 14. A sludge crushing chamber 20 is fixedly connected to the right side of the upper surface of the support plate 1. The elastic rod 11 includes a spring groove 401. A spring rod 402 is slidably connected inside the spring groove 401. A spring 2 403 is fixedly connected between the top of the spring rod 402 and the inner upper surface of the spring groove 401. First, sewage enters the sewage treatment chamber 4 and is temporarily stored in the arc-shaped water storage tank 5, where it undergoes preliminary treatment. Large particles are pushed by the push plate 12 in the push chamber 8. The push plate 12 is driven by the rotating rod 9, and the transmission teeth 10 on the rotating rod 9 are meshed with the rack 17 to ensure that the pushing action is continuous and stable. The back and forth swing of the push plate 12 separates the usable solid matter from the sewage and pushes it to the feed chamber 7. During the pushing process, the elastic rod 11 provides a buffer and reset function for the push plate, ensuring that the pushing action is smooth and without jamming. The leaking hole 13 on the push plate 12 further filters out the liquid part, and the solid waste and liquid are effectively separated. After being pushed, the hard material can be used to pass through the feeding cavity 7, fall to the upper surface of the conveying device 2, and be transported to the inside of the sludge crushing cavity 20, and then the solid waste will be further compressed and crushed for subsequent treatment or disposal. During the whole process, the intermittent air outlet of the intermittent air outlet cavity 19 ensures that the sliding plate 15 in the telescopic cavity 14 slides repeatedly in the telescopic cavity 14. The sliding plate 15 cooperates with the cross plate 16 to ensure that the rack 17 and the transmission gear 10 work together to ensure that the elastic rod 11 swings back and forth more smoothly. The elastic rod 11 is composed of a spring groove 401 and a spring rod 402. The spring rod 402 slides in the spring groove 401 to provide elastic support. The second spring 403 connects the top of the spring rod 402 and the inner surface of the spring groove 401 to provide elastic restoring force for the elastic rod 11, ensuring that the push plate 12 will not be stuck or move unsmoothly due to external force during the pushing process.

[0019] In this embodiment, the intermittent air outlet cavity 19 includes a cavity 101, a motor 102 is fixedly connected to the front surface of the cavity 101, the rear end of the output end of the motor 102 penetrates into the cavity 101, and is fixedly connected to a cam 103, an air squeezing plate 104 is slidably connected to the right side of the cavity 101, a plurality of springs 105 are fixedly connected between the right side of the air squeezing plate 104 and the right side of the cavity 101, an air outlet pipe 106 is fixedly connected to the right side of the cavity 101, and one end of the air outlet pipe 106 away from the cavity 101 is fixedly connected to the right side of the telescopic cavity 14; When the motor 102 is started, it drives the cam 103 to rotate through the output end, and the rotation of the cam drives the squeezing plate 104 to slide periodically. The sliding process of the squeezing plate 104 compresses the gas in the cavity, and pushes the squeezing plate 104 back to its original position through the restoring force of the spring 105. Each movement of the squeezing plate 104 will produce a gas discharge, and this discharge is intermittent. Finally, the gas is discharged through the outlet pipe 106 so that the pusher part can work normally.

[0020] In this embodiment, the conveying device 2 includes a support frame 201, the number of the support frames 201 is two, the outer side walls of the support frames 201 are rotatably connected to sprocket wheels 202, the outer side walls of the two sprocket wheels 202 are commonly fixedly connected to a chain belt 203, the outer side wall of the chain belt 203 is fixedly connected to a conveyor belt 204, the upper surface of the support plate 1 is symmetrically fixedly connected to a perforated support rod 205 located between the two support frames 201, a cross bar 206 is rotatably connected between the two perforated support rods 205, the outer side wall of the cross bar 206 is fixedly connected to a transmission sprocket wheel 207, the front end of the cross bar 206 is fixedly connected to a transmission lower wheel 208, the front end of the output end of the motor 102 is fixedly connected to a transmission upper wheel 209, and a transmission belt 210 is wound around the outer side walls of the transmission lower wheel 208 and the transmission upper wheel 209; When the motor 102 is started, the power output by the motor is transmitted to the lower transmission wheel 208 through the upper transmission wheel 209, and then the lower transmission wheel is driven to rotate through the transmission belt 210. The rotation of the lower transmission wheel 208 is transmitted to the chain belt 203 through the transmission sprocket 207, and then the two sprockets 202 are driven to rotate. The rotation of the sprocket 202 drives the conveyor belt 204 to operate smoothly, thereby realizing the transportation of materials. Through the coordinated work of these components, the conveying device 2 can continuously and stably transport the materials to be processed in the sewage treatment process, ensuring the operating efficiency of the entire equipment.

[0021] In this embodiment, the sludge crushing chamber 20 includes an oblique chamber 301, a feed port 302 is provided on the left side of the upper surface of the oblique chamber 301, a scraper 303 is fixedly connected to the left side of the oblique chamber 301, a guide plate 304 is fixedly connected to the right side of the scraper 303, a guide groove 305 is provided on the right side of the guide plate 304, and one end of the guide plate 304 away from the scraper 303 extends to the inside of the oblique chamber 301 through the feed port 302; During the process of sludge entering, since the conveying device 2 or other upstream devices may cause the sludge to be in a sticky state, the scraper 303 fixed on the left side of the oblique chamber 301 first takes effect. Since the conveying device 2 or other upstream devices may cause the sludge to be in a sticky state, the scraper 303 can perform preliminary scraping of the sticky sludge and guide it to the inside of the sludge crushing chamber 20 to prepare for the subsequent crushing operation. The sludge that has been preliminarily processed by the scraper 303 then comes to the guide plate 304 on the right. The guide groove 305 opened on the right side of the guide plate 304 can guide the sludge so that the sludge can move in a specific direction in a more orderly manner. One end of the guide plate 304 away from the scraper 303 extends to the inside of the inclined chamber 301 through the feed port 302, ensuring that the sludge follows the guidance of the guide plate 304 and accurately enters the inside of the inclined chamber 301, and contacts with the extrusion wheel 307 and other components in the inclined chamber 301. When the sludge enters the inside of the inclined chamber 301, as mentioned above, it is driven by the transmission motor 309, and the right gear 306 is driven to rotate through the transmission horizontal belt 310, and then the two mutually meshing gears 306 drive the vertical rod 312 and the extrusion wheel 307 fixed on the vertical rod 312 to rotate, so as to crush the sludge, and finally the crushed fragments are discharged from the crushing outlet 311.

[0022] In this embodiment, the inner lower surface of the oblique cavity 301 is symmetrically fixedly connected with a vertical rod 312, the top of the vertical rod 312 penetrates the outer wall of the oblique cavity 301, and is fixedly connected with a gear 306, the two gears 306 are meshed and connected, the outer wall of the vertical rod 312, located inside the oblique cavity 301, is fixedly connected with an extrusion wheel 307, the upper surface of the right gear 306 is fixedly connected with a transmission short column 308, the upper surface of the oblique cavity 301 is fixedly connected with a transmission motor 309 on the left side, and a transmission horizontal belt 310 is wound around the top of the output end of the transmission motor 309 and the transmission short column 308, and a crushed material outlet 311 is opened on the right side of the oblique cavity 301; When the transmission motor 309 is started, its output shaft rotates, driving the transmission belt 310 to move. The transmission belt 310 then drives the transmission short column 308 on the right gear 306, causing the right gear 306 to start rotating. Since the two gears 306 are meshed with each other, the left gear 306 will also rotate in the opposite direction. When the two gears 306 rotate, the vertical rod 312 connected thereto will be driven to rotate synchronously, thereby causing the extrusion wheel 307 fixed on the vertical rod 312 to rotate. When the material enters the inclined chamber 301, it will be squeezed by the rotating extrusion wheel 307. As the extrusion process proceeds, the extruded crushed material gradually moves in the inclined chamber 301, and is finally discharged from the crushed material outlet 311 opened on the right side of the inclined chamber 301, completing the extrusion, crushing and discharging process of the material.

[0023] In this embodiment, a plurality of grinding protrusions 21 are fixedly connected to the outer side wall of the extrusion wheel 307; A plurality of grinding convex points 21 are fixed to the outer wall of the extrusion wheel 307. When the rotating extrusion wheel 307 contacts the sludge, these grinding convex points 21 increase the friction and extrusion force with the sludge. During the relative rotation of the extrusion wheel 307, the grinding convex points 21 penetrate into the sludge, further grinding and refining the sludge, and strengthening the crushing effect of the sludge. The crushed fragments are affected by gravity and the force generated by the rotation of the extrusion wheel 307 in the inclined chamber 301, and are discharged from the fragment outlet 311 on the right side of the inclined chamber 301, completing the crushing process of the sludge.

[0024] In this embodiment, a water inlet pipe 22 is fixedly connected to the left side of the upper surface of the sewage treatment chamber 4; The water inlet pipe 22 is fixedly connected to the left side of the upper surface of the sewage treatment chamber 4. Its function is to introduce the source of wastewater to be treated into the sewage treatment chamber 4. When working, the wastewater of marble cutting sludge can be directly injected into the sewage treatment chamber 4 through the water inlet pipe 22. This makes the device more flexible and efficient in collecting wastewater when treating wastewater sludge.

[0025] In this embodiment, a drainage groove 23 is provided on the inner lower surface of the arc-shaped water storage groove 5, and an end of the drainage groove 23 away from the arc-shaped water storage groove 5 is fixedly connected to a water outlet pipe 24; As wastewater accumulates in the arc-shaped water storage tank 5, when a certain liquid level is reached, the wastewater will flow out through the drainage groove 23 provided on the inner lower surface of the arc-shaped water storage tank 5. The drainage groove 23 controls the outflow path of the wastewater, so that the wastewater can flow to the outlet pipe 24 fixedly connected thereto, and the outlet pipe 24 guides the wastewater flowing out of the drainage groove 23 to other treatment links of the device.

[0026] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
