Description

Technical Field

[0001] This utility model relates to the field of sludge thickening and dewatering technology, specifically to an integrated sludge thickening and dewatering machine. Background Technology

[0002] Sludge thickening and dewatering integrated machines typically first use flocculants to agglomerate fine particles in the sludge into larger flocs, then utilize gravity and pressure to achieve solid-liquid separation. Taking a common belt filter press as an example: after the sludge is thoroughly mixed with a flocculant, it flows into the feed distributor of the thickening section and is evenly distributed onto the inclined filter belt. Under the bidirectional guidance of the sludge rake and the action of gravity, free water is removed. After gravity dewatering, the thickened sludge is transported to the gravity dewatering section of a belt filter press for further dewatering. Then, it enters the wedge-shaped zone formed by the upper and lower filter belts for pre-compression, and then passes through an S-shaped arrangement of press rollers. Under the action of squeezing and shearing forces, free water and some capillary water are removed, finally forming a sludge cake.

[0003] Existing sludge thickening and dewatering integrated machines cause excessive accumulation of sludge after dewatering during operation, which can easily lead to blockages during sludge discharge. Therefore, a new design has been developed to address this issue. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a sludge thickening and dewatering integrated machine, comprising a composite shell, an adsorption mechanism fixedly connected to the middle of the outer side of the composite shell, a connecting shaft rotatably connected to the inner wall of the composite shell, and a paddle fixedly connected to the outer side of the connecting shaft. When the paddle drives the sludge to rotate and compress, it rubs against a screen, causing wastewater to be discharged outwards through the holes on the surface of the screen, thus achieving solid-liquid separation. One side of the connecting shaft is fixedly connected to the output end of a motor, which controls the rotation of the connecting shaft. The connecting shaft drives the paddle to rotate, thereby achieving the compression and conveying of the sludge, achieving the dewatering effect of the sludge, and expelling excess impurities from the sludge through compression. The composite shell is designed to concentrate sludge. A processing component is fixedly connected to the outer side of the composite shell away from the motor. A screening cover is fixedly connected to the inner wall of the composite shell near the processing component. A scraping mechanism is fixedly connected to the outer side of the connecting shaft near the motor. The scraping mechanism rotates with the connecting shaft to rub and clean impurities from the surface of the screening cover, reducing impurity accumulation on the component surface, preventing clogging of holes, and ensuring normal operation of the equipment. A drain pipe is fixedly connected to the outer side of the adsorption mechanism. During dewatering, wastewater flows towards the drain pipe to achieve drainage. A feed pipe is fixedly connected to the outer side of the composite shell near the motor. Legs are fixedly connected to both sides of the outer side of the composite shell.

[0005] The adsorption mechanism includes an adsorption shell, with an arc-shaped frame fixedly connected to the inner wall of the adsorption shell. A filter plate is inserted and connected to the inner side of the arc-shaped frame. Water carrying impurities fills the interior of the adsorption shell, and the filter plate adsorbs the impurities, reducing the amount of impurities adsorbed on the surface of the components. This controls the amount of impurities adhering, avoids excessive adhesion that could corrode the components, prevents blockage of the component pores, and thus maintains the normal operation of the equipment.

[0006] Preferably, the scraping mechanism includes an annular frame, an annular block rotatably connected to the outer side of the annular frame, and a scraping frame fixedly connected to the outer side of the annular block. When the scraping frame rotates, the annular block rotates on the annular frame, thereby maintaining uniform and stable rotation of the component. A receiving frame is fixedly connected to the outer side of the scraping frame away from the annular frame. The receiving frame controls the rotation of the scraping frame to scrape the outer side of the sieve cover, thereby removing impurities from the component surface, preventing clogging, preventing impact on the water output effect, preventing impact on the dewatering efficiency of the equipment, and thus extending the service life of the component. The inner side of the receiving frame is fixedly connected to the outer side of the connecting shaft.

[0007] Preferably, the processing component includes a processing housing, with a funnel plate fixedly connected to the bottom of the processing housing to guide the material discharge, reduce material adhesion, and ensure normal discharge of the equipment. A connecting shaft is rotatably connected to the inner wall of the processing housing, and a cutting mechanism is fixedly connected to the outer side of the connecting shaft. As the connecting shaft rotates, it drives the connecting shaft to rotate, causing the external support to control the rotation of the cutting block, thereby achieving the function of cutting the concentrated sludge, avoiding excessive accumulation of material, affecting the discharge speed, preventing blockage of the equipment, and thus maintaining normal operation of the equipment.

[0008] Preferably, one side of the connecting shaft is fixedly connected to the outer side of the connecting shaft, a fan is fixedly connected to the top of the processing housing, a grid cover is fixedly connected to the top of the fan, and a cleaning mechanism is fixedly connected to the outer side of the grid cover. The processing housing guides the discharge of sludge. The fan adopts an axial flow fan design, implementing bidirectional rotational air supply. When the fan blows air into the inside of the processing housing, it flushes impurities on the inner wall of the housing, thereby keeping the inside of the equipment clean, reducing internal moisture, reducing particle adhesion, avoiding corrosion of the housing, and extending the service life of components. The grid cover blocks external impurities from entering, and the funnel plate guides the material discharge, reduces material adhesion, and ensures normal material discharge from the equipment.

[0009] Preferably, the cutting mechanism includes an external column, and an external bracket is fixedly connected to the outside of the external column. The external bracket controls the rotation of the cutting block to achieve the function of cutting the concentrated sludge, avoiding excessive accumulation of material, affecting the discharge speed, preventing blockage of the equipment, and thus maintaining normal operation of the equipment. The cutting block is fixedly connected to the outside of the external bracket.

[0010] Preferably, the cleaning mechanism includes a fixed end, a receiving shaft rotatably connected to the inner side of the fixed end, an outer end fixedly connected to the outer side of the receiving shaft, a scraper fixedly connected to the outer side of the outer end, and a paddle fixedly connected to the outer side of the outer end away from the scraper. The paddle drives the receiving shaft to rotate, causing the scraper to rub against one side of the grid cover holes, thereby cleaning the particles on the surface of the component, reducing particle accumulation, preventing hole blockage, maintaining continuous air supply to the component, preventing obstruction of airflow, and thus maintaining normal operation of the equipment.

[0011] Beneficial effects

[0012] This utility model provides an integrated sludge thickening and dewatering machine. It has the following beneficial effects:

[0013] I. This sludge thickening and dewatering integrated machine, through the adsorption mechanism design, during the sludge dewatering process, the water flow carries impurities and fills the inside of the adsorption shell 41. The impurities are adsorbed by the filter plate 43, reducing the amount of impurities adsorbed on the surface of the components, thereby controlling the amount of impurities attached, avoiding excessive adhesion that could cause corrosion to the components, preventing the pores of the components from being blocked, and thus maintaining the normal operation of the equipment.

[0014] II. This sludge thickening and dewatering integrated machine features a scraping mechanism design. The receiving frame rotates with the connecting shaft, and the receiving frame controls the rotation of the scraping frame to scrape the outside of the screen cover, thereby removing impurities from the surface of the components. This prevents impurities from clogging the parts, thus avoiding affecting the effluent quality and the dewatering efficiency of the equipment, and extending the service life of the components. When the scraping frame rotates, the annular block rotates on the annular frame, thereby maintaining the uniform rotation of the components and ensuring stable rotation.

[0015] Third, this integrated sludge thickening and dewatering machine, through the design of its processing components, uses a processing shell to guide the discharge of sludge. The blower adopts an axial flow fan design, implementing bidirectional rotational air supply. When the blower sends air to the inside of the processing shell, it washes away impurities on the inner wall of the shell, thereby keeping the inside of the equipment clean, reducing internal moisture, reducing particle adhesion, avoiding corrosion of the shell, and extending the service life of the components. The grid cover prevents external impurities from entering, and the funnel plate guides the material discharge, reduces material adhesion, and ensures normal discharge of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Please see Figure 1-3This utility model provides a technical solution: a sludge thickening and dewatering integrated machine, including a composite shell 1, an adsorption mechanism 4 fixedly connected to the middle of the outer side of the composite shell 1, a connecting shaft 2 rotatably connected to the inner wall of the composite shell 1, a paddle 3 fixedly connected to the outer side of the connecting shaft 2, a side of the outer side of the connecting shaft 2 fixedly connected to the output end of a motor 9, a processing component 11 fixedly connected to the outer side of the composite shell 1 away from the motor 9, a screening cover 7 fixedly connected to the inner wall of the composite shell 1 near the processing component 11, a scraping mechanism 5 fixedly connected to the outer side of the connecting shaft 2 near the motor 9, a drain pipe 6 fixedly connected to the outer side of the adsorption mechanism 4, a feed pipe 8 fixedly connected to the outer side of the composite shell 1 near the motor 9, and two sides of the outer side of the composite shell 1 fixedly connected to the feed pipe 8. The system is connected to a support frame 10. Sludge enters the composite housing 1 through the feed pipe 8. The motor 9 controls the rotation of the connecting shaft 2, which in turn drives the paddle 3 to rotate, thereby achieving the squeezing and conveying of the sludge and dewatering it. The squeezing process removes excess impurities from the sludge, thus concentrating it. During the dewatering process, wastewater flows towards the drain pipe 6, thus draining the wastewater. When the paddle 3 drives the sludge to rotate, it rubs against the screen 7, causing the wastewater to be discharged from the holes on the surface of the screen 7, thus achieving solid-liquid separation. The scraping mechanism 5 rotates with the connecting shaft 2, thereby cleaning the impurities on the surface of the screen 7, reducing the accumulation of impurities on the surface of the components, preventing the holes from clogging, and ensuring the normal operation of the equipment.

[0024] The adsorption mechanism 4 includes an adsorption housing 41, with an arc-shaped frame 42 fixedly connected to the inner wall of the adsorption housing 41. A filter plate 43 is inserted and connected to the inner side of the arc-shaped frame 42. During the sludge dewatering process, water carrying impurities fills the interior of the adsorption housing 41. The filter plate 43 adsorbs the impurities, reducing their adsorption on the surface of the components. This controls the amount of impurities adhering, prevents excessive adhesion from corroding the components, and prevents blockage of the component pores, thus maintaining the normal operation of the equipment.

[0025] The scraping mechanism 5 includes an annular frame 51, with an annular block 52 rotatably connected to the outer side of the annular frame 51. A scraping frame 53 is fixedly connected to the outer side of the annular block 52. A receiving frame 54 is fixedly connected to the outer side of the scraping frame 53 away from the annular frame 51. The inner side of the receiving frame 54 is fixedly connected to the outer side of the connecting shaft 2. The receiving frame 54 rotates with the connecting shaft 2, controlling the rotation of the scraping frame 53 to scrape the outer side of the screen cover 7, thereby removing impurities from the component surface, preventing clogging, and preventing any impact on the water output and dewatering efficiency of the equipment, thus extending the service life of the component. When the scraping frame 53 rotates, it causes the annular block 52 to rotate on the annular frame 51, thereby maintaining uniform and stable rotation of the component.

[0026] Please see Figure 4-5The processing component 11 includes a processing housing 111. A funnel plate 112 is fixedly connected to the bottom of the processing housing 111. A connecting shaft 113 is rotatably connected to the inner wall of the processing housing 111. A cutting mechanism 114 is fixedly connected to the outer side of the connecting shaft 113. As the connecting shaft 113 rotates, the connecting shaft 113 rotates, causing the external support 1142 to control the rotation of the cutting block 1143, thereby achieving the function of cutting the concentrated sludge, avoiding excessive accumulation of material, affecting the discharge speed, preventing blockage of the equipment, and thus maintaining normal operation of the equipment. The funnel plate 112 guides the material to fall, thereby reducing material retention and maintaining continuous feeding of the equipment.

[0027] One side of the connecting shaft 113 is fixedly connected to the outside of the connecting shaft 2. A fan 115 is fixedly connected to the top of the processing housing 111. A grille cover 116 is fixedly connected to the top of the fan 115. A cleaning mechanism 117 is fixedly connected to the outside of the grille cover 116.

[0028] The treatment shell 111 serves to guide the discharge of sludge. The blower 115 adopts an axial flow fan design and implements bidirectional rotation air supply. When the blower 115 sends air to the inside of the treatment shell 111, it washes away impurities on the inner wall of the shell, thereby keeping the inside of the equipment clean, reducing internal moisture, reducing particle adhesion, avoiding corrosion of the shell, and extending the service life of the components. The grid cover 116 prevents external impurities from entering, and the funnel plate 112 guides the material discharge, reduces material adhesion, and ensures normal material discharge from the equipment.

[0029] The cutting mechanism 114 includes an outer column 1141, an outer bracket 1142 fixedly connected to the outer side of the outer column 1141, and a cutting block 1143 fixedly connected to the outer side of the outer bracket 1142. As the connecting shaft 2 rotates, it drives the connecting shaft 113 to rotate, causing the outer bracket 1142 to control the rotation of the cutting block 1143, thereby achieving the function of cutting the concentrated sludge, avoiding excessive accumulation of material, affecting the discharge speed, preventing blockage of the equipment, and thus maintaining normal operation of the equipment.

[0030] The cleaning mechanism 117 includes a fixed end 1171, a receiving shaft 1172 rotatably connected to the inner side of the fixed end 1171, an outer end 1173 fixedly connected to the outer side of the receiving shaft 1172, a scraper 1174 fixedly connected to the outer side of the outer end 1173, and a paddle 1175 fixedly connected to the outer side of the outer end 1173 away from the scraper 1174. When the fan 115 generates airflow and delivers airflow to one side of the grille cover 116, the airflow acts on the surface of the paddle 1175, causing the paddle 1175 to rotate and the receiving shaft 1172 to rotate. This causes the scraper 1174 to rub against one side of the holes in the grille cover 116, thereby cleaning particles from the surface of the component, reducing particle accumulation, preventing hole blockage, maintaining continuous airflow to the component, preventing obstruction of airflow, and thus maintaining normal equipment operation.

[0031] During operation, sludge enters the composite shell 1 through the feed pipe 8. The motor 9 controls the rotation of the connecting shaft 2, which in turn drives the paddle 3 to rotate, thereby achieving the squeezing and conveying of the sludge and dewatering it. The squeezing process removes excess impurities from the sludge, thus concentrating it. During dewatering, wastewater flows towards the drain pipe 6, thus draining the wastewater. As the paddle 3 rotates and squeezes the sludge, it rubs against the screen 7, causing the wastewater to be discharged from the holes on the surface of the screen 7, thus achieving solid-liquid separation. The scraping mechanism 5 rotates with the connecting shaft 2, thereby cleaning impurities from the surface of the screen 7, reducing the accumulation of impurities on the surface of the components, preventing the holes from clogging, and ensuring the normal operation of the equipment.

[0032] Sludge enters the treatment shell 111 from the composite shell 1. The treatment shell 111 guides the discharge of sludge. The blower 115 adopts an axial flow fan design and implements bidirectional rotation air supply. When the blower 115 sends air to the inside of the treatment shell 111, it washes away impurities on the inner wall of the shell, thereby keeping the inside of the equipment clean, reducing internal moisture, reducing particle adhesion, avoiding corrosion of the shell, and extending the service life of the components. The grid cover 116 blocks external impurities from entering, and the funnel plate 112 guides the material discharge, reduces material adhesion, and ensures normal discharge of the equipment.
