Description

Technical Field

[0001] The invention relates to the technical field of garbage storage and fermentation, in particular to a garbage storage and fermentation device with a conveying and preheating function. Background Art

[0002] In recent years, with the adjustment of relevant national industrial policies on waste disposal, power generation through waste incineration has become one of the main means of treating domestic waste.

[0003] For the current incineration process, fermentation is required before garbage incineration. However, in a low temperature environment, it is easy to cause incomplete fermentation of the garbage. The organic matter in the garbage cannot be completely converted into more stable compounds, thus affecting the calorific value of the garbage.

[0004] In addition, the fermentation process may also increase the water content of the garbage, and the types of domestic garbage are complex, and it is difficult to remove the water by conventional means. Since water cannot be burned in the subsequent incineration process, if the water content of the garbage is too high, it is easy to reduce the overall calorific value and affect the quality of incineration. Summary of the invention

[0005] The object of the present invention is to provide a garbage storage and fermentation device with a conveying and preheating function to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solution: a garbage storage and fermentation device with a conveying and preheating function.

[0007] A garbage storage and fermentation device with a conveying and preheating function, the storage and fermentation device comprises a fermentation tower, a power device, a discharging device and a conveying device, the conveying device and the fermentation tower are connected by a pipeline, the power device and the fermentation tower are connected, the discharging device and the fermentation tower are movably connected, the discharging device and the power device are transmission-connected, the conveying device comprises a shell, a preheating chamber is provided on the shell, the preheating chamber is connected to a heat source, a fermentation chamber is provided on the fermentation tower, and the fermentation chamber inlet is located on the side wall at the lower end.

[0008] The garbage is output through a conveying device, and the built-in preheating chamber of the shell is used to connect with the heat source. The conveyed garbage is preheated by supplying heat to the preheating chamber. After the preheating is completed, it is sent to the fermentation chamber of the fermentation tower for storage and fermentation. During the fermentation process, the heat generated is collected and serves as a heat source to reduce energy consumption. The fermented garbage is pressurized by a power device, and the water generated by the fermentation is discharged to avoid reducing the calorific value during the subsequent combustion process. After the fermentation is completed, the garbage is discharged from the fermentation chamber through the discharging device, and the energy utilization rate is improved by mixing the generated water with other liquid media and sending it into the preheating chamber.

[0009] Furthermore, the conveying device also includes an auger and a conveying motor, the conveying motor is tightly connected to the shell, the output end of the conveying motor is tightly connected to the auger, a material conveying trough is provided on the shell, the auger is placed in the material conveying trough, the preheating chamber is arranged along the outer layer of the material conveying trough, and the material conveying trough and the fermentation chamber pipeline are connected; The power device includes a driving motor and a driving shaft. The driving motor and the fermentation tower are tightly connected. The output end of the driving motor is connected to the driving shaft in a transmission manner. The driving shaft is placed in a fermentation chamber. The outer ring of the driving shaft is provided with paddles, which are arranged in a spiral shape. A driving chamber is provided in the driving shaft. A plurality of guide grooves are provided in the circumference of the driving chamber. A plurality of transmission components are built in the driving chamber. One end of the plurality of transmission components passes through the guide groove and is connected to the paddles in a transmission manner.

[0010] The conveying device serves as the main power source. The conveying motor provides torque to drive the auger to rotate in the material transport trough. The auger adopts a non-real shaft setting, which is convenient for garbage transportation. During the transportation process, the garbage is preheated in advance through the preheating chamber on the outer layer of the material transport trough, which reduces the storage time of the garbage in the fermentation chamber and improves the garbage fermentation efficiency. The driving motor is fixed on the fermentation tower, and the output end is inserted into the fermentation chamber to drive the driving shaft to rotate. The driving shaft is sleeved with paddles. During the rotation of the paddles, the fermented garbage can be discharged upward and discharged from the fermentation chamber through the discharging device. During the discharging process, the preheated garbage is continuously sent into the fermentation chamber through the auger, which improves the continuous processing efficiency. The paddles and drive shafts are designed in a split style, and the pitch is adjusted through the transmission assembly. The paddles are made of elastic metal sheets, which are allowed to deform under the action of force. When the action of force is removed, the deformation can be restored. When the control pitch is reduced, the vertical distance between the starting point and the end point within the same pitch is reduced. Since the length of the inner ring remains unchanged, the paddles connected to the transmission assembly maintain an unchanged spacing from the drive shaft, and the gap between other places and the drive shaft increases to generate a drainage gap. The drainage gap is controlled according to the fermentation time, and the water generated by the fermentation is automatically collected. This part of the water is hot water generated by fermentation heat. Automatic discharge can not only ensure its own calorific value, but also can be used for front transportation to preheat the garbage.

[0011] Furthermore, the transmission assembly includes an adjusting cylinder, a base is provided at the lower side of the adjusting cylinder, a card slot is provided on the base, the output end of the adjusting cylinder is inserted into the card slot at the upper end, a linkage rod is extended outward from the base, an end of the linkage rod away from the base passes through the guide slot and is fastened to the blade, the bottommost base is fastened to the wall of the driving cavity, and the remaining bases are movably connected to the driving cavity; In the initial state: the inner circle of the blade is in contact with the outer circle of the drive shaft, and the output end of the adjustment cylinder is located in the middle of the slot.

[0012] The paddle blades are partially fixed by the adjusting cylinder through the linkage rod on the outside of the base. The fixed node is a linkage rod at the beginning and end of each pitch length. A slot is set on the base, and the output end of the adjusting cylinder at the lower end is inserted into the slot on the upper side. The output end of the adjusting cylinder is set in a "T" shape and can slide in the slot. The adjacent adjusting cylinders maintain transmission through the base. The base at the bottom is fixed on the driving cavity. According to the pitch of the paddle blades, each pitch length is divided into a fermentation layer. A humidity sensor can be set on the driving shaft for each fermentation layer to detect the local fermentation degree. As the fermentation proceeds, water gradually precipitates. Since the stored garbage is an irregular body, it is not easy for water to escape from the garbage. The linkage rod is contracted to squeeze the fermentation layer with excessive water, thereby improving the water separation efficiency. At the same time, a drainage gap is generated, and the water flows downward along the wall of the driving shaft, which is convenient for automatic collection.

[0013] Furthermore, the vertical cross-section of the blade is arranged obliquely, and the inner circle of the blade is located at the low end.

[0014] By tilting the paddle blades, the outer circle is higher and the inner circle is lower. The water generated during the fermentation process flows downward under the action of gravity and is more likely to automatically gather near the drive shaft, so that the water in the garbage can be effectively drained.

[0015] Furthermore, the discharge device includes a sleeve and a discharge pipe. The sleeve is arranged in a stepped shape. The middle part of the sleeve is a through groove. A transmission groove is provided on the sleeve. The transmission groove is arranged along the lower end of the through groove. The upper end of the paddle is inserted into the transmission groove. The paddle is connected to the sleeve through the transmission groove. The sleeve is slidably connected to the upper end of the fermentation chamber. A discharge port is provided on one side of the fermentation chamber. A drain port is provided on the sleeve. One end of the discharge pipe is connected to the drain port, and the other end passes through the discharge port.

[0016] The discharge pipe is fixed by setting a sleeve, and the upper end of the paddle is stuck in the transmission groove of the sleeve. When the pitch of the paddle is adjusted, the overall length is reduced, and the sleeve is driven downward through the transmission groove. The transmission groove is a ring groove, so that during the transmission process of the paddle and the sleeve, only vertical displacement is transmitted, and torque is not transmitted, so as to avoid driving the discharge pipe to rotate and causing motion interference. When the fermentation is completed, the drive shaft is driven to rotate by the drive motor, so that the paddle pushes the garbage in a spiral manner, and falls into the through groove of the sleeve, and enters the discharge pipe through the discharge port, and is automatically discharged from the discharge pipe.

[0017] Furthermore, a liquid collecting chamber is provided at the bottom of the fermentation chamber, and the discharge device also includes a circulation pump, the circulation pump inlet is connected to the liquid collecting chamber pipeline, and the circulation pump outlet is connected to the preheating chamber pipeline.

[0018] When the drainage gap is generated, the water body that has been heated by fermentation flows downward along the driving shaft and finally falls into the liquid collecting chamber at the lower end, and is automatically collected by the liquid collecting chamber. After the collection is completed, it is directly pumped into the preheating chamber through the circulation pump. A good thermal conductor, such as copper, is used between the preheating chamber and the material transport trough to facilitate the preheating of the garbage entering the material transport trough and improve the subsequent fermentation efficiency.

[0019] As an optimization, the power device also includes a sealing sheet, which is set in an arc shape, and the curvature of the sealing sheet is adapted to the curvature of the wall of the driving chamber. The sealing sheet is sleeved on the base, and the base contacts the wall of the driving chamber through the sealing sheet. The sealing sheet is fixed on the base, and the base passes through one end of the sealing sheet to connect the linkage rod. The sealing sheet is set in an arc shape to seal the inner side of the guide groove to prevent the water generated by fermentation from flowing into the driving chamber through the guide groove during the central flow process, affecting the preheating efficiency.

[0020] As an optimization, the guide groove is a spiral groove. By setting the guide groove spirally, the spiral direction is the same as the blade direction. When the pitch is reduced, the first and last ends of the original fermentation layer no longer form a complete pitch in space, and the whole tends to expand, that is, the drainage gap increases, thereby improving the collection efficiency of the fermentation water.

[0021] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the driving shaft of the present invention is sleeved with paddles, and during the rotation of the paddles, the fermented garbage can be discharged upward and discharged from the fermentation chamber through the discharging device. During the discharging process, the preheated garbage is continuously sent into the fermentation chamber through the auger, thereby improving the continuous processing efficiency; the paddles and the driving shaft are designed in a split type, and the pitch is adjusted by the transmission component. The paddles are made of elastic metal sheets, which are allowed to deform under the action of force. When the action of force is removed, the deformation can be restored. When the control pitch is reduced, the vertical distance between the starting point and the end point within the same pitch is reduced. Since the length of the inner ring remains unchanged, the paddle connected to the transmission component locally maintains an unchanged spacing with the driving shaft, and the gap between other places and the driving shaft is increased, thereby generating a discharge. Liquid gap, the discharge gap is controlled according to the fermentation time, and the water generated by the fermentation is automatically collected. This part of the water is the hot water generated by the fermentation heat. Automatic discharge can not only ensure its own calorific value, but also can be used for front transportation to preheat the garbage; according to the blade pitch, each pitch length is divided into a fermentation layer, and a humidity sensor can be set on the drive shaft for each fermentation layer to detect the local fermentation degree. As the fermentation proceeds, water gradually precipitates. Since the stored garbage is an irregular body, it is not easy for water to separate from the garbage. The linkage rod is contracted to squeeze the fermentation layer with too much water to improve the water separation efficiency. At the same time, a liquid discharge gap is generated, and the water flows downward along the wall of the drive shaft, which is convenient for automatic collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The garbage is output through the conveying device 4, and the preheating chamber 412 built into the shell 41 is used to communicate with the heat source. The conveyed garbage is preheated by supplying heat to the preheating chamber 412. After the preheating is completed, it is sent to the fermentation chamber 11 of the fermentation tower 1 for storage and fermentation. During the fermentation process, the generated heat is collected and serves as a heat source to reduce energy consumption.

The driving motor 21 is tightly connected to the fermentation tower 1. The output end of the driving motor 21 is transmission-connected to the driving shaft 22. The driving shaft 22 is placed in the fermentation chamber 11. The outer ring of the driving shaft 22 is provided with a paddle 23. The paddle 23 is arranged in a spiral shape.

One end of the plurality of transmission components 24 passes through the guide groove 221 and is transmission-connected to the paddle 23.

[0028] The conveying device 4 serves as the main power source. The conveying motor 43 provides torque to drive the auger 42 to rotate in the material transport trough 411. The auger 42 is set without a real shaft to facilitate garbage transportation. During the transportation process, the garbage is preheated in advance through the preheating chamber 412 on the outer layer of the material transport trough 411, which reduces the storage time of the garbage in the fermentation chamber 11 and improves the garbage fermentation efficiency. The driving motor 21 is fixed on the fermentation tower 1, and the output end is inserted into the fermentation chamber 11 to drive the driving shaft 22 to rotate. The driving shaft 22 is provided with a paddle 23. During the rotation of the paddle 23, the fermented garbage can be discharged upward and discharged from the fermentation chamber through the discharging device 3. During the discharging process, the preheated garbage is continuously sent into the fermentation chamber 11 through the auger 42. Improve continuous processing efficiency; the paddle 23 and the drive shaft 22 adopt a split design, and the pitch is adjusted by the transmission component 24. The paddle 23 adopts an elastic metal sheet, which allows deformation under the action of force. When the action of force is removed, the deformation can be restored. When the control pitch is reduced, the vertical distance between the starting point and the end point within the same pitch is reduced. Since the length of the inner circle remains unchanged, the paddle 23 connected to the transmission component 24 partially maintains the same spacing with the drive shaft 22, and the gap between other places and the drive shaft 22 increases to generate a drainage gap. The drainage gap is controlled according to the fermentation time, and the water generated by the fermentation is automatically collected. This part of the water is hot water generated by fermentation heat. Automatic discharge can not only ensure its own calorific value, but also can be used for front transportation to preheat the garbage.

[0029] Further, the transmission assembly 24 includes an adjusting cylinder 241, a base 243 is provided at the lower side of the adjusting cylinder 241, a slot 2431 is provided on the base 243, the output end of the adjusting cylinder 241 is inserted into the slot 2431 at the upper end, a linkage rod 242 is extended outward from the base 243, one end of the linkage rod 242 away from the base 243 passes through the guide groove 221 and is fastened to the blade 23, the bottommost base 243 is fastened to the wall of the driving chamber 222, and the rest of the bases 243 are movably connected to the driving chamber 222; In the initial state: the inner circle of the blade 23 is in contact with the outer circle of the driving shaft 22 , and the output end of the regulating cylinder 241 is located in the middle section of the slot 2431 .

[0030] The blade 23 is partially fixed by the adjusting cylinder 241 through the linkage rod 242 on the outside of the base 243. The fixed node is a linkage rod 242 at the beginning and end of each pitch length. A slot 2431 is set on the base 243. The output end of the adjusting cylinder 241 at the lower end is inserted into the slot 2431 on the upper side. The output end of the adjusting cylinder 241 is set in a "T" shape and can slide in the slot 2431. The adjacent adjusting cylinders 241 maintain transmission through the base 243. The base 243 at the bottom is fixed to the drive cavity 222. On the top, according to the pitch of the blade 23, each pitch length is divided into a fermentation layer. A humidity sensor can be set on the drive shaft 22 for each fermentation layer to detect the local fermentation degree. As the fermentation proceeds, water gradually precipitates. Since the stored garbage is an irregular body, it is not easy for water to escape from the garbage. The linkage rod 242 is contracted to squeeze the fermentation layer with excessive water, thereby improving the water separation efficiency. At the same time, a drainage gap is generated, and the water flows downward along the wall of the drive shaft 22, which is convenient for automatic collection.

[0031] Furthermore, the vertical cross-section of the blade 23 is arranged obliquely, and the inner circle of the blade 23 is located at the low end.

[0036] When the drainage gap is generated, the water body that has been heated by fermentation flows downward along the driving shaft 22 and finally falls into the liquid collecting chamber 13 at the lower end, and is automatically collected by the liquid collecting chamber 13. After the collection is completed, it is directly pumped into the preheating chamber 412 through the circulation pump 33. A good thermal conductor, such as copper, is used between the preheating chamber 412 and the material transport trough 411 to facilitate the preheating of the garbage entering the material transport trough 411 and improve the subsequent fermentation efficiency.

The sealing sheet 25 is fixed on the base 243, and the base 243 passes through one end of the sealing sheet 25 to connect the linkage rod 242. The sealing sheet 25 is arranged in an arc shape to seal the inner side of the guide groove 221, so as to prevent the water generated by the fermentation from flowing into the driving chamber 222 through the guide groove 221 during the central flow process, thereby affecting the preheating efficiency.

[0038] As an optimization, the guide groove 221 is a spiral groove. By setting the guide groove 221 in a spiral configuration, the spiral direction is the same as the direction of the blade 23. When the pitch is reduced, the first and last ends of the original fermentation layer no longer form a complete pitch in space, and the whole tends to expand, that is, the drainage gap increases, thereby improving the collection efficiency of the fermentation water.

When the control pitch is reduced, the vertical distance between the starting point and the end point within the same pitch is reduced. Since the length of the inner ring remains unchanged, the paddle 23 connected to the transmission component 24 partially maintains the same spacing with the driving shaft 22, and the gap between other places and the driving shaft 22 increases, thereby generating The drainage gap is controlled according to the fermentation time, and the water generated by the fermentation is automatically collected. This part of the water is the hot water generated by the fermentation heat. The automatic discharge can not only ensure its own calorific value, but also can be used for pre-transportation to preheat the garbage; according to the pitch of the blade 23, each pitch length is divided into a fermentation layer, and each fermentation layer can be provided with a humidity sensor on the drive shaft 22 to detect the local fermentation degree.
