Description

Technical Field

[0001] This invention relates to the field of soil improvement technology, and in particular to an apparatus and method for using urban waste to improve clay soil. Background Technology

[0002] Soil improvement refers to a series of technical measures to improve soil properties, enhance soil fertility, and create favorable soil environmental conditions for crops. Its basic measures include: soil water management improvement to eliminate and prevent marshland formation and salinization; soil engineering improvement, such as using land leveling, terracing, and flood diversion to improve soil conditions; soil biological improvement, using various biological pathways to increase soil organic matter and improve soil fertility, or creating shelterbelts to prevent soil erosion; soil tillage improvement, improving soil conditions through improved tillage methods; and soil chemical improvement, such as applying chemical fertilizers and various soil conditioners to improve soil fertility, improve soil structure, and eliminate soil pollution.

[0003] The treatment and disposal of urban waste has not received enough attention in my country. In terms of awareness, urban waste is regarded as a problem of the waste disposal industry itself. At the same time, urban waste is often not completely crushed, resulting in poor effect on improving clay soil. In addition, during the fermentation and turning process, due to the large volume and heavy weight of the material, conventional stirring devices are extremely difficult to fully turn the material, which easily leads to the problem of insufficient fermentation.

[0004] To this end, we designed a device for improving clayey soil using urban waste and its application method. Summary of the Invention

[0005] The purpose of this invention is to solve the problems that urban waste is often not completely crushed and that conventional mixing devices are extremely difficult to fully tumble the materials, and to propose a device and method for improving clay soil using urban waste.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An apparatus for improving clayey soil using urban waste and its method of use include a mixing tank and a feeding box disposed above the mixing tank. The feeding box contains a crushing section for crushing and humidifying the urban waste. The outer wall of the feeding box is provided with a first motor for driving the crushing section and a water storage tank for humidifying the urban waste. The mixing tank contains an extrusion platform, and the extrusion platform is provided with a mixing section for mixing the crushed materials. The extrusion platform is provided with multiple extrusion sections for discharging the mixed materials.

[0009] Preferably, the pulverizing section includes:

[0010] Multiple second rotating shafts and multiple eccentric crushing blocks are arranged in parallel inside the feeding box, and the multiple eccentric crushing blocks are linearly fixed on the second rotating shafts.

[0011] A first connecting hole and a plurality of second connecting holes, the first connecting hole being coaxially opened on the second rotating shaft, the plurality of second connecting holes being linearly opened on the outer side wall of the second rotating shaft, and the first connecting hole being connected to the plurality of second connecting holes, the second rotating shaft being inserted into the water storage tank;

[0012] Multiple third connecting holes are provided, and the multiple third connecting holes are provided on the side wall of the eccentrically broken block. The third connecting holes are connected to the first connecting hole through the second connecting hole.

[0013] Preferably, the output end of the first motor is fixed with a second gear, and a first gear is coaxially sleeved on each of the plurality of second rotating shafts, and the second gear meshes with the first gear for transmission.

[0014] Preferably, the stirring section includes:

[0015] A first rotating shaft and multiple stirring plates, the multiple stirring plates being circumferentially fixed to the outer wall of the first rotating shaft, a second motor being provided on the outer wall of the stirring box, and the output end of the second motor being fixed to the first rotating shaft, and multiple through holes being provided on the stirring plates;

[0016] An end rocker plate is fixed to the end of the mixing plate and abuts against the curved surface of the extrusion base.

[0017] Preferably, the extrusion base has multiple threaded grooves on its curved surface for guiding material, and the bottom of the extrusion base has multiple discharge cavities.

[0018] Preferably, the extrusion section includes:

[0019] The inner cavity and the lower pressure block are provided. A baffle is fixed inside the inner cavity. The lower pressure block extends and retracts inside the inner cavity via a return spring. The two ends of the return spring are connected to the lower pressure block and the baffle, respectively.

[0020] A connecting pipe and a sleeve are connected sequentially to the bottom of the lower pressure block, and the same rotating rod passes through the connecting pipe and the sleeve.

[0021] The device comprises a spiral strip, a threaded groove, and an insert rod. A rotating cavity is provided on the connecting pipe, and the rotating cavity penetrates the lower pressure block. A discharge hole communicating with the rotating cavity is provided on the outer wall of the connecting pipe. The threaded groove is provided on the outer wall of the rotating rod, and the rotating rod rotates in the inner cavity. The insert rod is fixed to the inner wall of the sleeve and inserted into the threaded groove. The spiral strip is fixed to the outer wall of the rotating rod, and the discharge cavity is communicating with the inner cavity.

[0022] A method for using a device to improve clayey soil using urban waste, comprising the following specific steps:

[0023] S1: First, turn on the first motor to drive the second gear to rotate, and drive the first gears around it to rotate together. Since the first gear is fixed coaxially with the second rotating shaft, this will drive multiple second rotating shafts to rotate together, and will drive the eccentric crushing block to rotate together. In this way, the urban waste to be crushed is put into the feeding box, and the originally large pieces of urban waste are crushed.

[0024] S2: Then, a water pump is installed in the water storage tank to pour the clean water in the water storage tank into the first connecting hole in the second rotating shaft, and then flow through the second connecting hole into the third connecting hole in the eccentric crushing block, and then flow out from the third connecting hole, thus completing the humidification operation of the crushed urban waste.

[0025] S3: Then the crushed and moist urban waste will fall into the mixing tank, and then the corresponding fermentation material will be poured in through the gap between the mixing tank and the top cover. Then the second motor will be driven to make the mixing part rotate and mix. During the mixing process, the mixture will rotate and be pushed along the threaded groove. The direction of rotation of the threaded groove is opposite to the direction of rotation of the mixing part, so that the crushed urban waste and the fermentation material can be better mixed.

[0026] S4: When the mixing plate rotates, the end rocker plate at its end abuts against the curved surface of the extrusion base. Since the top of the lower pressure block is inclined, it will continuously press down on the lower pressure block during the rotation of the end rocker plate. During the pressing down of the lower pressure block, its insert rod is fixed to the inner wall of the sleeve and inserted into the threaded groove. As the rotating rod rotates in the inner cavity, it will drive the spiral strip on the rotating rod to rotate. The spiral strip rotates with the spiral pointing downward, which can draw the crushed urban waste on the lower pressure block into the rotating cavity. Under the action of the rotating spiral strip, not only is the crushed urban waste and fermentation material mixed again, but the material can also be squeezed out of the discharge hole. The squeezed material will fall into the inner cavity and flow out from the discharge cavity. This part of the mixed material will flow out from the discharge pipe at the bottom of the mixing box.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. In this invention, the first motor drives the second gear to rotate, and drives the surrounding first gears to rotate together. Since the first gear is coaxially fixed with the second rotating shaft, this will drive multiple second rotating shafts to rotate together, and will also drive the eccentric crushing block to rotate together. In this way, the urban waste to be crushed is put into the feeding box, and the originally large pieces of urban waste are crushed.

[0029] 2. In this invention, the crushed and moist urban waste falls into the mixing tank, and then the corresponding fermentation material is poured in through the gap between the mixing tank and the top cover. Then, the second motor is driven to make the mixing part rotate and mix. During the mixing process, the mixture will rotate and be pushed along the threaded groove, and the rotation direction of the threaded groove is opposite to the rotation direction of the mixing part. This can better mix the crushed urban waste and the fermentation material. Attached Figure Description

[0042] Reference Figures 1-8 An apparatus for improving clayey soil using urban waste includes a mixing tank 1 and a feeding box 7 disposed above the mixing tank 1. A top cover 2 is provided above the mixing tank 1, and the top cover 2 has a feeding hole 10. The feeding box 7 is fixed on the top cover 2, and the top cover 2 is connected to the mixing tank 1 through a connecting rod 3. A discharge pipe 13 is provided through the bottom of the mixing tank 1 to facilitate the centralized discharge of the mixed materials.

[0043] The feeding box 7 is equipped with a crushing section 9 for crushing and humidifying municipal waste. The crushing section 9 includes multiple second rotating shafts 91 and multiple eccentric crushing blocks 94. The multiple second rotating shafts 91 are arranged in parallel in the feeding box 7, and the multiple eccentric crushing blocks 94 are linearly fixed on the second rotating shafts 91. The first motor 5 drives the second gear 97 to rotate, and drives the surrounding first gears 96 to rotate together. Since the first gears 96 are coaxially fixed with the second rotating shafts 91, this will drive the multiple second rotating shafts 91 to rotate together, and will drive the eccentric crushing blocks 94 to rotate together. In this way, the municipal waste to be crushed is put into the feeding box 7, and the originally large pieces of municipal waste are crushed.

[0044] The crushing section 9 also includes a first connecting hole 92 and a plurality of second connecting holes 93. The first connecting hole 92 is coaxially opened on the second rotating shaft 91, and the plurality of second connecting holes 93 are linearly opened on the outer side wall of the second rotating shaft 91. The first connecting hole 92 is connected to the plurality of second connecting holes 93. The outer side wall of the feeding box 7 is provided with a first motor 5 for driving the crushing section 9 and a water storage tank 4 for humidifying the municipal waste. The second rotating shaft 91 is inserted into the water storage tank 4. The water storage tank 4 is provided with a water pump to facilitate the filling of the clean water in the water storage tank 4 into the first connecting hole 92 in the second rotating shaft 91.

[0045] Multiple third connecting holes 95 are formed on the side wall of the eccentric crushing block 94. The third connecting holes 95 are connected to the first connecting hole 92 through the second connecting hole 93. Then, the water flows into the third connecting hole 95 in the eccentric crushing block 94 through the second connecting hole 93 and then flows out from the third connecting hole 95. This completes the humidification operation of the crushed urban waste.

[0046] The output end of the first motor 5 is fixed with a second gear 97. A first gear 96 is coaxially sleeved on multiple second rotating shafts 91, and the second gear 97 meshes with the first gear 96 for transmission. When the first motor 5 is turned on, the first motor 5 drives the second gear 97 to rotate, which in turn drives the surrounding first gears 96 to rotate together. Since the first gear 96 is coaxially fixed with the second rotating shaft 91, this will drive multiple second rotating shafts 91 to rotate together, and will also drive the eccentric crushing block 94 to rotate together.

[0047] A material extrusion platform 11 is provided inside the mixing chamber 1. Then, the crushed and moist urban waste falls into the mixing chamber 1, and the corresponding fermentation material is poured in through the gap between the mixing chamber 1 and the top cover 2, and falls into the material extrusion platform 11. The material extrusion platform 11 is provided with a mixing part 8 for mixing the crushed materials. The curved surface of the material extrusion platform 11 is provided with multiple threaded grooves 12 for guiding the material. Multiple discharge chambers 16 are opened at the bottom of the material extrusion platform 11. The mixing part 8 includes a first rotating shaft 8 and multiple mixing plates 82. The multiple mixing plates 82 are circumferentially fixed to the outer wall of the first rotating shaft 8. A second motor 6 is provided on the outer wall of the mixing chamber 1, and the output end of the second motor 6 is fixed to the first rotating shaft 8. Multiple through holes 83 are opened on the mixing plates 82 to drive the second motor 6, so that the second motor 6 drives the mixing part 8 to rotate and mix. During the mixing process, the mixture will rotate and push along the threaded grooves 12. The rotation direction of the threaded grooves 12 is opposite to the rotation direction of the mixing part 8, so as to better mix the crushed urban waste and the fermentation material.

[0048] The mixing section 8 also includes an end rocker plate 84, which is fixed to the end of the mixing plate 82 and abuts against the curved surface of the extrusion base 11. Since the top of the pressure block 14 is inclined, the pressure block 14 will be continuously pressed during the rotation of the end rocker plate 84.

[0049] The extrusion base 11 is provided with multiple extrusion sections for discharging the mixed materials. Each extrusion section includes an inner cavity 15 and a downward pressing block 14. A baffle 17 is fixed inside the inner cavity 15. The downward pressing block 14 extends and retracts within the inner cavity 15 via a return spring 18. The two ends of the return spring 18 are connected to the downward pressing block 14 and the baffle 17, respectively. During the downward pressing process of the pressed downward pressing block 14, its insert rod is fixed to the inner wall of the sleeve 25 and inserted into the threaded groove 24. As the rotating rod 22 rotates within the inner cavity 15, it drives the spiral strip 23 on the rotating rod 22 to rotate. When the spiral strip 23 rotates, the spiral faces downward, which can draw the crushed urban waste on the downward pressing block 14 into the rotating cavity 20.

[0050] The extrusion section also includes a connecting pipe 19 and a sleeve 25. The connecting pipe 19 and the sleeve 25 are connected in sequence to the bottom of the lower pressure block 14. The same rotating rod 22 passes through the connecting pipe 19 and the sleeve 25. The rod is fixed to the inner wall of the sleeve 25 and inserted into the threaded groove 24. Since the rotating rod 22 rotates in the inner cavity 15, it will drive the spiral strip 23 on the rotating rod 22 to rotate.

[0051] The extrusion section also includes a spiral strip 23, a threaded groove 24, and an insert rod. A rotating cavity 20 is provided on the connecting pipe 19, and the rotating cavity 20 passes through the lower pressure inclined block 14. The outer wall of the connecting pipe 19 is provided with a discharge hole 21 that communicates with the rotating cavity 20. The threaded groove 24 is provided on the outer wall of the rotating rod 22. The rotating rod 22 rotates in the inner cavity 15. The insert rod is fixed on the inner wall of the sleeve 25 and is inserted into the threaded groove 24. The spiral strip 23 is fixed on the outer wall of the rotating rod 22. The discharge cavity 16 communicates with the inner cavity 15. Under the action of the rotating spiral strip 23, not only is the crushed urban waste and fermented material mixed again, but the material is also extruded through the discharge hole 21. The extruded material falls into the inner cavity 15 and flows out from the discharge cavity 16. This part of the mixed material flows out from the discharge pipe 13 at the bottom of the mixing tank 1.

[0052] A method for using a device to improve clayey soil using urban waste, comprising the following specific steps:

[0053] S1: First, turn on the first motor 5, so that the first motor 5 drives the second gear 97 to rotate, and drives the surrounding first gears 96 to rotate together. Since the first gear 96 is coaxially fixed with the second rotating shaft 91, this will drive multiple second rotating shafts 91 to rotate together, and will drive the eccentric crushing block 94 to rotate together. In this way, the urban waste to be crushed is put into the feeding box 7, and the originally large pieces of urban waste are crushed.

[0054] S2: Then, the water tank 4 is equipped with a water pump to pour the clean water in the water tank 4 into the first connecting hole 92 in the second rotating shaft 91, and then flow into the third connecting hole 95 in the eccentric crushing block 94 through the second connecting hole 93, and then flow out from the third connecting hole 95, thus completing the humidification operation of the crushed urban waste.

[0055] S3: Then the crushed and moist urban waste will fall into the mixing tank 1, and then the corresponding fermentation material will be poured in through the gap between the mixing tank 1 and the top cover 2. Then the second motor 6 will be driven to drive the mixing part 8 to rotate and mix. During the mixing process, the mixture will rotate and be pushed along the threaded groove 12. The rotation direction of the threaded groove 12 is opposite to the rotation direction of the mixing part 8, so that the crushed urban waste and the fermentation material can be better mixed.

[0056] S4: When the mixing plate 82 rotates, the end rocker plate 84 at its end abuts against the curved surface of the extrusion base 11. Since the top of the pressure block 14 is inclined, the end rocker plate 84 will continuously press the pressure block 14 during the rotation process. During the pressing process, the rod of the pressure block 14 is fixed to the inner wall of the sleeve 25 and inserted into the threaded groove 24. Since the rotating rod 22 rotates in the inner cavity 15, it will drive the spiral strip 23 on the rotating rod 22 to rotate. The spiral strip 23 rotates downward, so that the crushed urban waste on the pressure block 14 can be drawn into the rotating cavity 20. Under the action of the rotating spiral strip 23, not only is the crushed urban waste and fermentation material mixed again, but the material can also be squeezed out of the discharge hole 21. The squeezed material will fall into the inner cavity 15 and flow out from the discharge cavity 16. This part of the mixed material will flow out from the discharge pipe 13 at the bottom of the mixing box 1.
