Description

Technical Field

[0001] This invention belongs to the technical field of sludge treatment, and relates to a sludge treatment machine and treatment method. Background Technology

[0002] With the acceleration of industrialization and urbanization, large amounts of silt have accumulated at the bottom of rivers, lakes, and reservoirs. This silt not only contains abundant nutrients but may also contain harmful substances such as heavy metals. The accumulation of silt not only affects the water storage capacity of water bodies but also leads to water quality deterioration, impacting the ecological environment and human health. Therefore, silt treatment is necessary to optimize the environment.

[0003] Currently, the process of treating sludge typically involves first using a filter press to dewater the sludge, squeezing out the water and creating dry sludge suitable for subsequent use. However, existing filter presses require diluting the sludge to improve its fluidity before feeding it into the press for dewatering. After dewatering, the dry sludge must be removed from the filter press before new sludge can be fed in for the next round of processing. This batch-by-batch operation not only increases the complexity of the process but also prolongs the overall processing cycle, impacting processing efficiency. Summary of the Invention

The bottom of the guide frame is connected to the discharge pipe. A screw feed shaft is rotatably connected inside the guide frame. A scraper is connected to the upper part of the guide frame, and the scraper is in contact with the inner wall of the filter plate.

[0006] Preferably, the drive assembly includes a drive motor and a drive gear. The drive motor is mounted on the base, and the drive gear is connected to the output shaft of the drive motor. The drive gear meshes with the large external gear ring.

[0007] Preferably, the system also includes a squeezing mechanism, which includes a guide plate and a pressure roller. An inclined guide plate is provided between two side plates, and a pressure roller is rotatably connected to the top of the guide plate. The pressure roller is capable of squeezing sludge.

[0008] Preferably, the unloading mechanism further includes an internal gear ring and a transmission gear. The internal gear ring is connected to the rotating drum, and the transmission gear is connected to the spiral feeding shaft. The transmission gear meshes with the internal gear ring.

[0009] Preferably, the system also includes a coarse filtration mechanism, which includes a coarse filter cylinder, a small external gear ring, and a pinion. The coarse filter cylinder is rotatably connected between the middle of the two side plates. The small external gear ring is connected to the coarse filter cylinder. The pinion is rotatably connected to one of the side plates. The pinion meshes with the small external gear ring and the transmission gear on both sides, respectively.

[0010] Preferably, the system also includes a water pumping mechanism, which includes an air suction pipe, an air extraction pipe, a solenoid valve, and a baffle plate. Multiple air extraction pipes are evenly spaced on the processing cylinder, and air suction pipes are connected between the multiple air extraction pipes. Two baffle plates are provided on the inner side wall of the processing cylinder, and the area between the two baffle plates forms a water pumping cavity. The rear end of the air extraction pipe is located in the water pumping cavity, and a solenoid valve is installed on the lower baffle plate.

[0011] Preferably, a rinsing mechanism is also included, which includes a water pump, a suction pipe, a guide pipe, an outlet pipe, and a nozzle. The water pump is installed at the lower part of the base. The suction pipe connects the inlet end of the water pump to the bottom of the treatment cylinder. Multiple nozzles are evenly spaced on the treatment cylinder. The outlet end of each nozzle is aligned with the filter plate. Guide pipes connect the multiple nozzles. An outlet pipe connects the guide pipe to the outlet end of the water pump.

[0012] Preferably, a dilution mechanism is also included, which comprises a second nozzle, a water guide pipe, a second water pump, a suction pipe, and a connecting pipe.

A connecting pipe is connected to the outlet end of the second water pump, and the connecting pipe is connected to the two water guide pipes.

[0013] The present invention also provides a method for treating sludge, the specific steps of which are as follows:

[0014] S1: The sludge is loaded into the rotating drum through the opening in the middle of the two side plates. The filter plates filter the water in the sludge, and the filtered water enters the lower part of the treatment drum. Open the valve, and the water will be discharged through the drain pipe.

[0015] S2: Control the drive motor to drive the drive gear to rotate. The rotation of the drive gear drives the large external gear ring to rotate. The rotation of the large external gear ring drives the rotating drum and filter plate to rotate. The rotation of the rotating drum drives the sludge inside to move. The sludge moves and contacts the guide plate and pressure roller. The guide plate and pressure roller squeeze the sludge and perform filter pressing treatment on the sludge.

[0016] S3: The residual sludge adheres to the inner wall of the rotating drum and filter plate. The rotating drum and filter plate continue to rotate, causing the sludge to come into contact with the scraper. The scraper scrapes the sludge down to the guide frame, where it is collected.

[0017] S4: When the drum rotates, it can drive the internal gear ring to rotate. The rotation of the internal gear ring drives the transmission gear to rotate. The rotation of the transmission gear drives the screw feed shaft to rotate. The rotation of the screw feed shaft can guide the sludge in the frame to be transported backward and discharged through the discharge pipe, thereby completing the treatment of sludge.

[0018] 1. In the process of treating sludge, the sludge is put into the treatment cylinder and then filtered by pressure rollers and guide plates. The dried sludge after treatment can be scraped off by scrapers and sent out by screw feed shaft. There is no need to stop the operation of the machine to send out the dried sludge, which makes the operation more convenient and efficient.

[0019] 2. In the process of processing, the sludge can be added into the coarse filter tube, so that the sludge can be initially filtered through the coarse filter tube, and impurities such as stones mixed in the sludge can be filtered out, so as to achieve the effect of initially filtering large impurities in the sludge.

[0020] 3. After the sludge is added into the coarse filter cylinder, water can be sprayed onto the sludge through nozzle two to dilute the sludge, enhance its fluidity, and allow it to pass through the coarse filter cylinder and enter the rotating cylinder for pressure filtration.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] A sludge treatment machine, such as Figures 1-5 As shown, it includes a base 1, a processing cylinder 2, a drain pipe 3, a filtration mechanism, and a discharge mechanism. The processing cylinder 2 is connected to the upper part of the base 1. Multiple drain pipes 3 are evenly spaced at the bottom of the processing cylinder 2. Valves are installed at the drain pipes 3. The processing cylinder 2 is equipped with a filtration mechanism for filtering sludge. The filtration mechanism is equipped with a discharge mechanism for unloading dry sludge.

[0033] like Figure 2 and Figure 3As shown, the filtration mechanism includes side plates 41, a rotating cylinder 42, filter plates 43, a large external gear ring 44, and a drive assembly. The processing cylinder 2 is connected to side plates 41 on both the left and right sides. An opening for adding sludge is provided in the middle of the two side plates 41. The rotating cylinder 42 is rotatably connected between the two side plates 41. Multiple filter plates 43 are evenly spaced on the rotating cylinder 42. The filter plates 43 are used to filter water from the sludge. The rotating cylinder 42 is connected to the left and right sides on both sides. The base 1 is provided with a drive assembly, which can drive the large external gear ring 44 to rotate.

[0034] like Figure 3 As shown, the drive assembly includes a drive motor 51 and a drive gear 52. The drive motor 51 is mounted on the left side of the base 1. The drive gear 52 is connected to the output shaft of the drive motor 51. The drive gear 52 meshes with the large external gear ring 44 so that the operation of the drive motor 51 can drive the large external gear ring 44 to rotate through the drive gear 52.

[0035] like Figure 4 As shown, it also includes a squeezing mechanism, which includes a guide plate 61 and a pressure roller 62. An inclined guide plate 61 is provided between the lower left sides of the two side plates 41. The guide plate 61 can squeeze the sludge. The top of the guide plate 61 is rotatably connected to the pressure roller 62, which can squeeze the sludge, thereby performing sludge pressure filtration.

[0036] like Figure 3 and Figure 5 As shown, the unloading mechanism includes a guide frame 71, a discharge pipe 72, an internal gear ring 73, a transmission gear 74, a screw feed shaft 75, and a scraper 76. The guide frame 71 is connected between the upper parts of the two side plates 41. The discharge pipe 72 is connected to the bottom right side of the guide frame 71. The internal gear ring 73 is connected to the left side of the rotating drum 42. The screw feed shaft 75 is rotatably connected inside the guide frame 71. The rotation of the screw feed shaft 75 can transport the sludge, thereby discharging the sludge through the discharge mechanism. The feed tube 72 is used to feed the material out. A transmission gear 74 is connected to the left side of the spiral feeding shaft 75. The transmission gear 74 meshes with the internal gear ring 73 so that when the rotating drum 42 rotates, it can drive the spiral feeding shaft 75 to rotate through the internal gear ring 73 and the transmission gear 74. A scraper 76 is connected to the upper part of the guide frame 71. The scraper 76 is in contact with the inner wall of the filter plate 43 so that when the rotating drum 42 and the filter plate 43 rotate, the scraper 76 can scrape off the sludge from the inner wall of the filter plate 43.

[0037] When sludge needs to be treated, this device can be used. During treatment, the sludge is first loaded into the rotating drum 42 through the opening between the two side plates 41. The filter plate 43 filters the water in the sludge, and the filtered water enters the lower part of the treatment cylinder 2. Then, the valve can be opened to allow the water to drain through the drain pipe 3. After the sludge is added to the rotating drum 42, the drive motor 51 can be controlled to drive the drive gear 52 to rotate. When the drive gear 52 rotates, it drives the large external gear ring 44 to rotate, which in turn drives the rotating drum 42 and the filter plate 43 to rotate. The rotation of the rotating drum 42 causes the sludge inside to move. As the sludge moves, it comes into contact with the guide plate 61 and the pressure roller 62, which then squeeze the sludge, thus processing it. The filtration process allows water mixed in with the sludge to pass through the filter plate 43, while the remaining sludge adheres to the inner walls of the rotating drum 42 and the filter plate 43. The rotation of the rotating drum 42 and the filter plate 43 then causes the sludge to come into contact with the scraper 76, which scrapes the sludge onto the guide frame 71 for collection. The rotation of the rotating drum 42 also drives the internal gear ring 73, which in turn drives the transmission gear 74. The transmission gear 74, in turn, drives the screw feed shaft 75, which in turn conveys the sludge from the guide frame 71 backwards, discharging it through the discharge pipe 72. This process is repeated, allowing for continuous addition and treatment of sludge. After treatment, there is no need for manual removal of the remaining sludge, making operation more convenient.

[0038] like Figure 6 and Figure 7 As shown, it also includes a coarse filtration mechanism, which includes a coarse filter cylinder 81, a small external gear ring 82, and a pinion 83. The coarse filter cylinder 81 is rotatably connected between the middle of the two side plates 41. The small external gear ring 82 is connected to the left side of the coarse filter cylinder 81, and the pinion 83 is rotatably connected to the left side plate 41. The two sides of the pinion 83 mesh with the small external gear ring 82 and the transmission gear 74, respectively, so that when the transmission gear 74 rotates, it can drive the small external gear ring 82 to rotate through the pinion 83.

[0039] When adding sludge, the sludge can be added into the coarse filter cylinder 81 first. Impurities such as gravel mixed in the sludge will be blocked by the coarse filter cylinder 81, while the sludge and water can pass through the coarse filter cylinder 81 and enter the rotating cylinder 42, thereby achieving the effect of preliminary filtration of the sludge. When the transmission gear 74 rotates, it can drive the small external gear ring 82 to rotate through the pinion 83, thereby driving the coarse filter cylinder 81 to rotate, which helps to throw out the sludge and water inside the coarse filter cylinder 81 and prevent the sludge and water from clogging the inside of the coarse filter cylinder 81.

[0040] like Figure 8As shown, it also includes a water pumping mechanism, which includes an air suction pipe 91, an air extraction pipe 92, a solenoid valve 94, and a baffle plate 93. Multiple air extraction pipes 92 are evenly spaced on the front side of the processing cylinder 2, and air suction pipes 91 are connected between the front sides of the multiple air extraction pipes 92. Two baffle plates 93 are provided on the front wall of the inner side of the processing cylinder 2, and the area between the two baffle plates 93 forms a water pumping cavity. The rear end of the air extraction pipe 92 is located in the water pumping cavity, and a solenoid valve 94 is installed on the lower baffle plate 93.

[0041] When using this processor, the suction end of the air pump can be connected to the air extraction pipe 92. Then, the air pump can be controlled to operate, which will cause the air extraction pipe 92 to extract air, creating negative pressure in the water extraction cavity. This helps to extract the water remaining on the sludge adhering to the inner wall of the filter plate 43. The extracted water will be located in the water extraction cavity. When a certain amount of water accumulates in the water extraction cavity, the air pump can be turned off, and the solenoid valve 94 at the lower baffle plate 93 can be opened to discharge the water. In this way, the effect of extracting the water remaining in the sludge can be achieved.

[0042] like Figure 4 As shown, it also includes a rinsing mechanism, which includes a water pump 101, a suction pipe 102, a guide pipe 103, an outlet pipe 105, and a nozzle 104. The water pump 101 is installed at the lower part of the base 1. The suction pipe 102 connects the liquid inlet end of the water pump 101 to the bottom of the treatment cylinder 2. Multiple nozzles 104 are evenly spaced on the rear side of the treatment cylinder 2. The water outlet end of the nozzle 104 is aligned with the filter plate 43. The guide pipe 103 connects the rear sides of the multiple nozzles 104. The outlet pipe 105 connects the guide pipe 103 to the water outlet end of the water pump 101.

[0043] When water enters the bottom of the treatment cylinder 2, the valve can be closed, and then the water pump 101 can be operated to draw water through the suction pipe 102 and inject the water into the nozzle through the outlet pipe 105 and guide pipe 103. The water is sprayed onto the filter plate 43 through the nozzle to wash away the sludge stuck in the holes of the filter plate 43 and prevent sludge from getting stuck in the holes of the filter plate 43.

[0044] like Figure 9 As shown, it also includes a dilution mechanism, which includes a second nozzle 112, a water guide pipe 111, a second water pump 113, a water suction pipe 114, and a connecting pipe 115. Two water guide pipes 111 are connected between the lower parts of the two side plates 41. Multiple second nozzles 112 are evenly spaced on each of the two water guide pipes 111. The second nozzles 112 face the coarse filter cartridge 81. A second water pump 113 is installed on the left side of the base 1. The inlet end of the second water pump 113 is connected to the treatment cartridge 2 by a water suction pipe 114. The outlet end of the second water pump 113 is connected to a connecting pipe 115. The connecting pipe 115 is connected to the two water guide pipes 111.

[0045] After the control valve is closed, the water pump 2 113 can also be controlled to operate to draw water out through the water pumping pipe 114 and inject it into the connecting pipe 115. Then, the water is injected into the water guide pipe 111 through the connecting pipe 115. Finally, the water is sprayed out through the nozzle 2 112, thereby spraying the water into the coarse filter cartridge 81, diluting the sludge in the coarse filter cartridge 81, so that the sludge can pass through the coarse filter cartridge 81 better.

[0046] This embodiment also provides a sludge treatment method, the specific steps of which are as follows:

[0047] S1: The sludge is loaded into the rotating drum 42 through the opening in the middle of the two side plates 41. The filter plate 43 filters the water in the sludge. The filtered water enters the lower part of the treatment drum 2. When the valve is opened, the water will be discharged through the drain pipe 3.

[0048] S2: Control the drive motor 51 to drive the drive gear 52 to rotate. The rotation of the drive gear 52 drives the large external gear ring 44 to rotate. The rotation of the large external gear ring 44 drives the rotating drum 42 and the filter plate 43 to rotate. The rotation of the rotating drum 42 drives the sludge inside it to move. The sludge moves and contacts the guide plate 61 and the pressure roller 62. The guide plate 61 and the pressure roller 62 squeeze the sludge and perform pressure filtration on the sludge.

[0049] S3: The residual sludge adheres to the inner wall of the rotating drum 42 and the filter plate 43. The rotating drum 42 and the filter plate 43 continue to rotate, causing the sludge to come into contact with the scraper 76. The scraper 76 scrapes the sludge down to the guide frame 71, and the guide frame 71 collects the sludge.

[0050] S4: When the rotating drum 42 rotates, it can drive the internal gear ring 73 to rotate. The rotation of the internal gear ring 73 drives the transmission gear 74 to rotate. The rotation of the transmission gear 74 drives the screw feed shaft 75 to rotate. The rotation of the screw feed shaft 75 can guide the sludge in the guide frame 71 to be transported backward and discharged through the discharge pipe 72, thereby completing the treatment of sludge.
