Description

Technical Field

[0001] The present invention relates to the technical field of soil purification, and in particular to an integrated processing device for grading and classifying oil sludge. Background Art

[0002] With the continuous development of economy, energy consumption is increasing and environmental pollution is becoming more and more serious. In particular, with the continuous increase in the scale of industrial and agricultural production, the demand for crude oil is increasing. In the process of crude oil extraction, purification and processing, oily soil and other oily wastes will be generated, and the amount will increase year by year in a certain period.

[0003] At present, technologies for purifying oil pollution are being developed and applied. Among the technologies for removing oil-containing pollutants, chemical hot washing technology, incineration technology, pyrolysis technology, microbial remediation technology, etc. are more commonly used. It is a consensus in the industry that each oil field needs to classify and sort the ground sludge containing impure oil or with large differences in particle size distribution, tank cleaning sludge, and mixed storage sludge when chemically washing. At the same time, when applying other processes such as pyrolysis, incineration, microbial and other processes to treat oil field sludge, it is also necessary to sort and classify the sludge to improve efficiency and ensure the treatment effect.

[0004] Traditional sorting devices can only perform general sorting, and there are problems such as low sorting accuracy, poor sorting effect, poor oil recovery due to oil-water mixing, poor cleaning effect, high equipment failure rate and difficulty in maintenance, and low oil enrichment recovery rate. After sorting, there are problems such as too much debris adhering to oil products. At the same time, soft materials after sorting by conventional or traditional sorting devices are wrapped with a large amount of mud and sand, which also causes the subsequent incineration or pyrolysis of these debris. The yield of solid phase residue is too high, and the cost of landfilling these pyrolysis and incineration residues is high. Another obvious consensus is that traditional classification and sorting devices are mainly sorting, with weak cleaning functions, and the materials need secondary treatment after sorting. Summary of the invention

[0005] The purpose of the present invention is to provide an integrated treatment device for sludge grading and classification, which improves the cleaning effect of water on grease in soil, further improves the purification effect of soil, and also improves the purification efficiency of soil, thereby achieving energy saving and environmental protection.

[0006] To achieve the above-mentioned purpose, the technical solution of the present application is: an integrated sludge classification and treatment device, comprising a box filled with hot water, a pushing mechanism arranged on the box, and an adding mechanism arranged on the box and used to add hot water into the box, wherein the pushing mechanism comprises:

[0007] A rotating cage, wherein the rotating cage is rotatably arranged on the housing and is in a horizontal state, the rotating cage is immersed in hot water and is used to push the soil to move and stir the soil along the axis of the rotating cage, the housing is divided into a first collection area and a second collection area along the axis of the rotating cage, a plurality of first filter holes for mud and sand to pass through are evenly provided on the rotating cage and located in the first collection area, a plurality of second filter holes for sand and gravel to pass through are evenly provided on the rotating cage and located in the second collection area, the aperture of the second filter hole is larger than the aperture of the first filter hole, the rotating cage rotates so that the soil passes through the first filter hole and the second filter hole in sequence, and at this time, the light garbage is moved to the outside of the rotating cage for collection;

[0008] A driving assembly, which is arranged on the box body and is used to drive the rotating cage to rotate;

[0009] A first collecting assembly and a second collecting assembly, wherein the first collecting assembly and the second collecting assembly are arranged on the box body and are used to collect the silt in the first collecting area and the sand and gravel in the second collecting area respectively;

[0010] The floating oil collecting assembly is arranged on the box body and is used for collecting floating oil on the water.

[0011] By adopting the above technical solution, soil is continuously added to the rotating cage, and at the same time, the driving component is started to drive the rotating cage to rotate. The rotating cage drives the soil to move and stir the soil, and the soil is immersed in hot water, so that the grease in the soil forms floating oil and floats to the water surface, and the mud and sand in the soil settle into the first collection area through the first filter hole, and the first collection component is used to collect the mud and sand; at the same time, the sand and gravel with a larger diameter continue to move and wash during the rotation of the rotating cage, and then the sand and gravel are moved to the second collection area. After washing, the sand and gravel settle downward through the second filter hole, and the second collection component is used to collect the sand and gravel. At the same time, the light garbage continues to move to the outside of the rotating cage for collection under the rotation of the rotating cage, and the floating oil washed off by the hot water floats on the water surface. The floating oil moves under the action of the rotation of the rotating cage and approaches the floating oil collection component, and the floating oil collection component is used to collect the floating oil, so as to remove the floating oil in the water, thereby improving the purification effect of the soil, and also realizing the classification and treatment of the sludge, thereby improving the treatment efficiency of the soil.

[0012] The soil is stirred and turned by continuous rotation of the cage to loosen the soil, so that the grease in the soil forms floating oil and floats to the water surface. The first collecting component is used to collect mud and sand, and the second collecting component is used to collect sand and gravel. At the same time, the light garbage is also transferred to the outside of the cage for collection, so as to continuously clean the grease in the soil and clean the light garbage. At the same time, the soil is screened and cleaned in sections, and the floating oil in the water is subsequently removed, thereby improving the cleaning effect of water on the grease in the soil and further improving the purification effect of the soil; and compared with the structure in the prior art that can only realize a single function, the present application integrates and optimizes multiple functions, thereby improving the soil purification effect, and also improving the soil purification efficiency, thereby achieving energy saving and environmental protection.

[0013] Optionally, the first collecting component includes:

[0014] A sedimentation box, which is arranged on the bottom of the box body and is used to collect the sediment settled in the first collection area;

[0015] A screw conveyor, which is rotatably disposed on the bottom of the sedimentation tank and is used to convey silt;

[0016] A collecting motor, which is arranged on the sedimentation tank and is used to drive the screw conveyor to rotate;

[0017] A sediment output pipe, which is arranged on the bottom of the sedimentation tank and is used to receive the sediment output by the screw conveyor;

[0018] A storage box is arranged on the sediment output pipe and is used to collect the output sediment; the storage box and the sediment output pipe are provided with a control component which closes the sediment output pipe when the storage box is opened or opens the sediment output pipe when the storage box is closed.

[0019] By adopting the above technical solution, the control component controls the storage box to be closed and the sediment output pipe to be opened, and the sediment falls into the sedimentation box through the first filter hole, and the collection motor is started to drive the screw conveyor to rotate. The screw conveyor stirs the sediment and also pushes the sediment to move, so that the residual grease in the sediment continues to float up under the stirring action, and at the same time, the sediment enters the sediment output pipe under the action of the screw conveyor, and finally the sediment enters the storage box for storage. At the same time, with the entry of the sediment, the sewage entering the storage box moves up and flows back from the storage box, and the screw conveyor generates thrust on the sediment when pushing the sediment to move, thereby squeezing the sediment in the storage box, so that more hot water in the storage box flows back to the sedimentation box and the box body, thereby reducing the water content of the sediment in the storage box.

[0020] After a period of time, the storage box is full of sediment, and the control component controls the sediment output pipe to close and then open the storage box, and the sediment in the storage box is output for collection, while the sediment can continue to accumulate in the sediment output pipe for collection. After the sediment in the storage box is output, the control component controls the storage box to close and then open the sediment output pipe, so that the sediment can continue to be stored in the storage box, thereby improving the convenience of sediment collection, while also reducing the waste of hot water, and achieving energy saving and environmental protection.

[0021] Optionally, a drainage assembly is provided on the sediment output pipe, and the drainage assembly includes:

[0022] A drainage pipe, which is arranged on the sediment output pipe and located above the control assembly and is used to output water in the sediment output pipe;

[0023] A filter plate, which is detachably arranged at the connection between the drainage pipe and the sediment output pipe and is used to filter the sediment;

[0024] A water collecting tank, which is arranged on the drain pipe and is used to collect water;

[0025] A water collecting pump is arranged on the water collecting tank and is used for outputting water in the water collecting tank and is connected with the adding mechanism.

[0026] By adopting the above technical scheme, the sediment is pushed and squeezed through the sediment output pipe into the storage box for storage, while the water in the storage box flows back to the sedimentation box and the box body through the sediment output pipe. When the water passes through the sediment output pipe, part of the water passes through the filter plate and enters the drain pipe, and finally the water flows into the water collecting tank for collection. When the water collecting tank is full, the water collecting pump starts to flow the water in the water collecting tank to the adding mechanism for recovery, thereby further reducing the waste of hot water; at the same time, another channel is added for water return, thereby improving the water return efficiency, allowing more water in the sediment to flow back, improving the water recovery effect, and also reducing the probability of the water returning and pushing the sediment in the sediment output pipe and the storage box to move up and re-enter the sedimentation box, thereby further improving the convenience of sediment collection, while also reducing the waste of hot water, achieving instant environmental protection.

[0027] Optionally, the control component includes:

[0028] A first plate body and a second plate body, wherein the first plate body and the second plate body are movably arranged on the sediment output pipe and the storage box, respectively, so that after the sediment output pipe is closed, the storage box is opened to realize sediment output, or after the storage box is closed, the sediment output pipe is opened to realize sediment storage in the storage box;

[0029] A first driving member and a second driving member are respectively arranged on the sediment output pipe and the storage box and are respectively used to drive the first plate body and the second plate body to move.

[0030] By adopting the above technical solution, when the storage box is needed to store mud and sand, the second driving member starts to drive the second plate body to move and close the storage box, and then the first driving member drives the first plate body to open the mud and sand output pipe, so that the mud and sand can be added to the storage box through the mud and sand output pipe; after the storage box is full of mud and sand, the first driving member starts to drive the first plate body to move and close the mud and sand output pipe, and the mud and sand continue to accumulate on the first plate body for storage, and the water in the mud and sand output pipe continues to flow back upward, and then the second driving member starts to drive the second plate body to open the storage box, so that the mud and sand in the storage box are output, and after the mud and sand are output, the action of storing mud and sand is repeated, and the mud and sand accumulated on the first plate body falls downward into the storage box for storage.

[0031] When sediment is stored in the storage box, the sediment entering will squeeze the water backflow, thereby discharging the water in the storage box, so that the water content in the sediment in the storage box is less; and when the sediment in the storage box is discharged, the sediment can continue to accumulate on the first plate body and discharge the water at the same time. When the sediment in the storage box is discharged, the sediment accumulated on the first plate body can directly fall and be stored in the storage box, so that the discharge of the sediment will not be interrupted when the sediment in the storage box is discharged, thereby improving the sediment discharge efficiency, thereby improving the soil purification efficiency.

[0032] Optionally, the rotating cage is divided into a first cylindrical section, a connecting section and a second cylindrical section along the rotating cage axis, the diameter of the connecting section gradually decreases and the diameters at both ends are respectively the same as the diameters of the first cylindrical section and the second cylindrical section, and the diameter of the first cylindrical section is larger than the diameter of the second cylindrical section; the water level in the box body is located below the second cylindrical section, the connecting section is located above the second collecting assembly and is provided with a plurality of floating oil holes for floating oil to pass through, and the driving assembly is connected to the second cylindrical section.

[0033] By adopting the above technical solution, the sand and gravel enter the second collection area and are settled through the second filter holes. However, mud and sand will remain on the sand and gravel, so that the sand and gravel will not pass through the second filter holes. Therefore, the sand and gravel that have not fallen will move upwardly and tiltedly after entering the connecting section from the first cylindrical section, so that the sand and gravel will continue to move back to the second filter holes after rolling down. During the movement of the sand and gravel, the mud and sand on the sand and gravel will be washed by water, so that the returned sand and gravel can be settled through the second filter holes, but the light garbage cannot pass through the second filter holes and move upwardly and tiltedly, so that the water and floating oil adhering to the light garbage also move downward and reflux. The rotation of the cage drives the light garbage to be removed from the cage for collection, thereby reducing water waste and the difficulty of subsequent light garbage treatment.

[0034] The rotation of the cage causes the grease in the soil to form floating oil floating on the water surface, and the rotation of the cage pushes the water, floating oil and soil to move in the same direction, and the floating oil is located above the sediment and sand and gravel, reducing the probability of the floating oil continuing to move onto the sediment and sand and gravel. Finally, the floating oil moves to the floating oil collection assembly through the floating oil hole for collection, thereby further improving the cleaning effect of the floating oil in the soil and improving the soil purification effect and efficiency; at the same time, the second cylindrical section is located above the water and the floating oil, and the driving assembly is connected to the second cylindrical section, thereby reducing the probability of the driving assembly being damaged by contact with water and floating oil, improving the life of the driving assembly and the stability during operation, and improving the soil purification efficiency.

[0035] Optionally, the second collecting component includes:

[0036] A collecting box, which is arranged at the bottom of the box body and is used to collect sand and gravel in the second collecting area;

[0037] A sand and gravel output pipe is arranged on the bottom of the collection box and is used to output sand and gravel. A storage box and a control component are also arranged on the sand and gravel output pipe. A sand barrier plate for blocking the passage of sand and gravel and allowing sewage to pass through is arranged on the side wall of the collection box and located on the side close to the floating oil collection component. The floating oil in the box is located above the sand barrier plate.

[0038] By adopting the above technical scheme, sand and gravel sink downward into the collection box, and the sand and gravel output operation method is the same as the mud and sand output operation method, thereby reducing water waste, improving the convenience of sand and gravel output, and improving soil purification efficiency; at the same time, when sand and gravel accumulate in the collection box, part of the water flows back to the box body located above the collection box, and part of the water enters the box body through the sand partition plate, thereby further improving the water recovery effect, thereby reducing water waste, improving the convenience of sand and gravel output, and improving soil purification efficiency.

[0039] The storage box and the sedimentation box collect the settled sand and silt separately, thereby reducing the probability of silt entering the collection box under the rotation of the rotating cage, and further improving the soil purification effect and efficiency.

[0040] Optionally, the floating oil collection assembly is located below the second cylindrical section and is connected to the floating oil hole, and the floating oil collection assembly includes:

[0041] The first control panel, the second control panel, the third control panel and the fourth control panel are arranged on the box body at intervals along the axis direction of the rotating cage, and the bottom ends of the first control panel, the third control panel and the fourth control panel are connected to the bottom wall of the box body; the first control panel, the second control panel and the box body cooperate to form an oil collecting tank for water and floating oil in the box body to overflow into, and the third control panel, the fourth control panel and the box body cooperate to form a sewage tank, and the bottom end of the second control panel and the bottom wall of the box body form an overflow channel, and the second control panel, the third control panel and the box body cooperate to form an overflow cavity that is connected with the oil collecting tank through the overflow channel and the water overflows into the sewage tank, and a storage area for collecting light garbage is formed between the fourth control panel and the inner side wall of the box body; the top of the first control panel is located above the third control panel, and the tops of the second control panel and the fourth control panel are located above the first control panel;

[0042] An oil receiving pipeline, which is arranged on the box body and located above the third control panel and is connected to the oil collecting tank;

[0043] A circulating water pipe is arranged on the box body and is located below the third control panel and is connected to the sewage tank; the circulating water pipe is connected to the adding mechanism.

[0044] By adopting the above technical scheme, the floating oil floats on the water surface, so the floating oil first overflows into the oil collecting tank, and part of the water also enters the oil collecting tank, while the floating oil in the oil collecting tank continues to float on the water surface, so that the water in the oil collecting tank enters the overflow chamber through the overflow channel, and the density of the floating oil is less than the density of water. Therefore, according to the pressure formula, when the pressure balance between the oil collecting tank and the overflow chamber is maintained, the liquid level of the floating oil in the oil collecting tank must be higher than the liquid level of the water in the overflow chamber, so that the floating oil in the oil collecting tank is first output through the oil collection pipeline for collection. At the same time, as the water and floating oil increase, the liquid levels of the floating oil in the oil collecting tank and the water in the overflow chamber will also rise, so that the floating oil is removed through the oil collection pipeline, and the water in the overflow chamber overflows into the sewage tank for collection, so that the floating oil and water can be separated, the floating oil in the water is removed, and then the water in the sewage tank is recycled, thereby improving the purification effect and efficiency of the soil.

[0045] The third control panel has a certain height to ensure the size of the sewage tank. Then, due to the floating oil floating on the water surface and the pressure difference, the sewage and the floating oil can be separated when the third control panel has a higher height, thereby improving the removal effect of the floating oil and improving the soil purification effect and efficiency; the light garbage falls into the storage area for storage, and when there is too much water in the sewage tank, it can overflow into the storage area for buffering, reducing the probability of sewage overflowing outside the box.

[0046] Optionally, the adding mechanism includes:

[0047] A heating pipe, which is arranged in the sewage tank and is used to heat the sewage;

[0048] An adding pump, the adding pump is arranged on the box body and is connected to the circulating water pipe;

[0049] A water supply pipe, which is arranged on the supply pump and is connected to an end of the box body away from the circulating water pipe;

[0050] A water level detector is arranged in the box and is used to detect the water level in the box and is electrically connected to the adding pump.

[0051] By adopting the above technical solution, the water level detector detects the water level height in the box, and the heating pipe heats and keeps the water in the sewage tank warm. When the water level is lower than the specified value, the adding pump is started, and the hot water in the sewage tank enters the box through the water adding pipe, so that the water level in the box is maintained at a certain height, thereby ensuring the cleaning effect of hot water on the soil, improving the purification effect and efficiency of the soil, and at the same time, the input hot water impacts the soil and moves in the direction of the rotating cage, thereby further improving the purification effect and efficiency of the soil.

[0052] Optionally, a stirring assembly is provided on the sedimentation box and between the rotating cage and the screw conveyor, and the stirring assembly includes:

[0053] A stirring rod, which is rotatably arranged on the sedimentation box and located between the rotating cage and the screw conveyor and is used to stir the silt, and the axis of the stirring rod is parallel to the axis of the rotating cage;

[0054] A stirring blade, wherein the stirring blade is arranged on the stirring rod;

[0055] a first gear and a second gear, wherein the first gear and the second gear are respectively arranged on the screw conveyor and the stirring rod;

[0056] A connecting gear is rotatably arranged on the sedimentation box and meshes with the first gear and the second gear. The number of teeth on the connecting gear is less than the number of teeth on the first gear and greater than the number of teeth on the second gear.

[0057] By adopting the above technical solution, the rotation of the screw conveyor drives the first gear to rotate, the rotation of the first gear drives the connecting gear to rotate, the rotation of the connecting gear drives the second gear and the stirring rod to rotate, the rotation of the stirring rod drives the stirring blades to rotate to stir the sediment, so that the sediment rises to further clean the grease in the sediment, thereby improving the soil purification effect and efficiency.

[0058] At the same time, the number of teeth on the connecting gear is less than the number of teeth on the first gear and greater than the number of teeth on the second gear. Therefore, according to the transmission ratio, the rotation speed of the stirring rod is greater than the rotation speed of the screw conveyor and the two rotate in the same direction, thereby improving the stirring effect on the sediment and further improving the soil purification effect and efficiency.

[0059] Optionally, the stirring blade is detachably mounted with a mounting bar, and the mounting bar is provided with a brush for cleaning the first filter hole.

[0060] By adopting the above technical solution, the brush is used to clean the first filter hole, thereby ensuring the rate at which sediment passes through the first filter hole and improving the purification effect and efficiency of the soil.

[0061] Due to the adoption of the above technical scheme, the present invention can achieve the following technical effects: the soil is stirred and turned by the continuous rotation of the cage so that the grease in the soil forms floating oil and floats to the water surface; the first collecting component is used to collect mud and sand, and the second collecting component is used to collect sand and gravel, and at the same time, the light garbage is transferred to the outside of the cage for collection, thereby continuously cleaning the grease in the soil and cleaning the light garbage, while screening the soil and cleaning it in sections, and subsequently removing the floating oil in the water, thereby improving the cleaning effect of water on grease in the soil and further improving the purification effect of the soil.

[0090] Reference Figure 1 , Figure 2 and Figure 6 The oil collection pipeline 95 is fixedly installed on the outer wall of the accommodating portion 12, and the oil collection pipeline 95 is located above the third control panel 93 and is connected to the oil collecting tank 911; the circulating water pipe 96 is fixedly installed on the outer wall of the accommodating portion 12, and the circulating water pipe 96 is located below the top of the third control panel 93 and is connected to the sewage tank 932, and the circulating water pipe 96 is connected to the adding mechanism 10; at the same time, a water outlet pipe 85 connected to the sewage tank 932 is fixedly installed on the water collecting pump 84. When the water collecting pump 84 is started, the sewage in the water collecting box 83 flows back into the sewage tank 932, and a one-way valve is fixedly installed on the water outlet pipe 85. The one-way valve allows the water in the water outlet pipe 85 to only enter the sewage tank 932.

[0091] The adding mechanism 10 includes a heating pipe 101, an adding pump 102, a water adding pipe 103, and a water level detector 104. The heating pipe 101 is fixedly installed in the sewage tank 932 and is used to heat and keep the sewage warm. The adding pump 102 is fixedly installed on the outer wall of the accommodating portion 12. The adding pump 102 is fixedly connected to the circulating water pipe 96. A control box for controlling the start and stop of the adding pump 102 is fixedly installed on the accommodating portion 12; the water adding pipe 103 is fixedly installed on the adding pump 102, and the water adding pipe 103 is fixedly connected to the upper surface of the installation portion 11 near one end of the input pipe 13. When the adding pump 102 is started, the hot water in the sewage tank 932 is added to the installation portion 11 through the water adding pipe 103, and water can also be added to the sewage tank 932 for replenishment.

[0092] The water level detector 104 is fixedly mounted on the inner wall of the mounting portion 11. The water level detector 104 detects the water level in the mounting portion 11, so that the hot water level is located above the collecting box 51, the sedimentation box 41 and the first control panel 91, and the hot water level is located below the second cylindrical section 26; at the same time, a plurality of floating oil holes 251 for floating oil to pass through are provided on the connecting section 25 and located above the collecting box 51 and the sedimentation box 41. The floating oil on the water surface in the mounting portion 11 is located on the inner side of the cage body 22. The floating oil enters the accommodating portion 12 through the floating oil hole 251 as pushed by water and soil. At the same time, water can also pass through the floating oil hole 251. Then the floating oil and water overflow into the oil collecting tank 911. The floating oil continues to float on the water surface, and the water enters the overflow chamber 931 under the squeezing of the floating oil.

[0093] As the amount of floating oil and water increases, the floating oil level in the oil collecting tank 911 and the water level in the overflow chamber 931 both rise. At the same time, according to the pressure formula P=ρgh, the density ρ of the floating oil is less than the density ρ of water, and the oil collecting tank 911 is connected to the overflow chamber 931. When the pressure balance between the two is maintained, the floating oil level in the oil collecting tank 911 is higher than the water level in the overflow chamber 931, so that the floating oil first overflows through the oil collection pipeline 95 for collection, and then as the amount of floating oil and water increases, the floating oil in the oil collecting tank 911 continues to be collected through the oil collection pipeline 95, and at the same time, the water in the overflow chamber 931 overflows into the sewage tank 932 for collection, thereby removing the floating oil in the water. The heating tube 101 heats the sewage in the sewage tank 932, and the water level detector 104 checks the water level height in the installation part 11. When the water level is detected to be lower than the specified value, the adding pump 102 is started, and the sewage in the sewage tank 932 enters the installation part 11 through the water adding pipe 103. At the same time, the entering water pushes the water and floating oil in the installation part 11 to move toward the first control panel 91, thereby continuously removing the floating oil in the soil.

[0094] The working principle of the embodiment of the present application is as follows:

[0095] Soil is continuously added to the cage 22 through the feed hopper 14 and the input pipe 13, and the drive motor 32 is started to drive the cage 22 and the spiral blade 23 to rotate simultaneously, thereby stirring and turning the soil and pushing the soil and water to move. At the same time, the soil is soaked in hot water, so that the soil is loosened to form mud and sand, and the oil in the soil floats to the water surface to form floating oil. The mud and sand settle downward into the sedimentation box 41 through the first filter hole 27, and the sand and gravel continue to move and settle downward into the collection box 51 through the second filter hole 28 for collection. At the same time, water enters the containing part 12 through the sand isolation plate 53, and the floating oil enters the containing part 12 through the floating oil hole 251.

[0096] The floating oil and water continue to move and overflow into the oil collecting tank 911. The floating oil in the oil collecting tank 911 continues to float on the water surface, and the water enters the overflow chamber 931. As the amount of water and floating oil increases, the floating oil height is higher than the water height in the overflow chamber 931. Therefore, the floating oil first overflows through the oil collecting pipeline 95 for collection. At the same time, as the amount of water and floating oil continues to increase, the water in the overflow chamber 931 overflows into the sewage tank 932, and the floating oil continues to overflow through the oil collecting pipeline 95 for collection, thereby removing the floating oil in the water. The heating pipe 101 heats and insulates the water in the sewage tank 932. The water level detector 104 detects the water level in the installation part 11. The adding pump 102 is started to add the hot water in the sewage tank 932 to the installation part 11, thereby maintaining the water level in the installation part 11 at a certain height, thereby improving the efficiency and effect of soil purification.

[0097] The collecting motor 43 starts to drive the screw conveyor 42 to rotate, so that the sediment in the sedimentation box 41 enters the storage box 45 for storage, and the water flows back to the sedimentation box 41 and the mounting portion 11 under the push of the sediment until the sediment in the storage box 45 is full of sediment, and the first driving member 73 starts to drive the first plate 71 to move and close the sediment output pipe 44, and then the second driving member 74 starts to control the sediment output in the storage box 45, and at the same time, the sediment continues to accumulate on the first plate 71. After the sediment in the storage box 45 is output, the second driving member 74 starts to control the storage box 45 to close, and then the first driving member 73 starts to control the sediment output pipe 44 to open, so that the storage box 45 can continue to store sediment, and the sediment on the first plate 71 directly falls into the storage box 45. At the same time, the gravel output is the same as the sediment output operation, so that the content of hot water in the output sediment and gravel is low, thereby improving the convenience of sediment and gravel collection, improving the soil purification efficiency, and also reducing the loss of hot water, achieving energy saving and environmental protection.
