Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household garbage treatment, in particular to a household garbage comprehensive treatment system of extrusion drying type. BACKGROUND

[0002] The fermentation treatment of household garbage is a resourceful treatment mode for decomposing and converting the organic components in household garbage through biochemical action of microorganisms, mainly including anaerobic fermentation and aerobic fermentation. The anaerobic fermentation is to decompose organic matter by anaerobic microorganisms under anaerobic conditions to produce biogas, realizing garbage reduction, and the biogas can be recycled as energy. The aerobic fermentation is to make organic matter compost through metabolic activity of aerobic microorganisms in an aerobic environment, forming organic fertilizer for agriculture. Therefore, the fermentation treatment of household garbage can realize the reuse of waste resources.

[0003] In the process of aerobic fermentation of household garbage, the water content in the garbage is large, which not only occupies the fermentation space, but also causes the pores of the garbage fragments to be filled with water, hindering the penetration of oxygen, destroying the aerobic fermentation environment, inhibiting the activity of microorganisms, and further affecting the fermentation of organic garbage. Therefore, it is particularly important to control the water content of garbage fermentation.

[0004] The existing garbage dewatering device mainly adopts a belt conveying and extruding device, which uses a conveying belt to convey the garbage, and uses an extruding roller to extrude and dewater the garbage during the conveying process. Generally, such device has a long production line, occupies a large space in the transverse direction, has high requirements for site area and layout, increases the construction cost and the difficulty of space planning, and has poor garbage conveying stability during long-distance conveying, thereby affecting the extrusion and dewatering efficiency.

[0005] In addition, there is also a downward pressing type garbage dewatering device on the market, which places the garbage into a dewatering tank below, and extrudes the water in the garbage by pressing the plate downward. After the dewatering of a batch of garbage is completed, the extruded garbage needs to be poured out and new batch of garbage to be dewatered is reloaded, which leads to frequent stop, unloading and loading operations, significantly prolongs the stop time, reduces the continuous operation efficiency of the equipment, and also makes it difficult to adapt to the large-scale and continuous production demand of garbage dewatering due to the intermittent treatment.

[0043] Please refer to Figure 1 The present application provides a kind of extrusion drying type domestic waste comprehensive treatment system, including sorting device 01, crushing device 02, extrusion drying equipment 03, fermentation equipment 04 and sewage treatment equipment 05, wherein, sorting device 01, crushing device 02, fermentation equipment 04 and sewage treatment equipment 05 all use prior art, specific structure and principle are not detailed, sorting device 01 is communicated with crushing device 02 by conveying pipeline, sorting device 01 is used to classify domestic waste, to separate organic waste that can be fermented, and the separated organic waste is conveyed to crushing device 02 by pipeline, for crushing, to facilitate subsequent fermentation;

[0044] Extrusion drying equipment 03 is vertical layout, but it does not occupy horizontal space excessively, and the feeding part on extrusion drying equipment 03 is communicated with crushing device 02 by conveying pipeline, and crushing device 02 conveys the crushed organic waste to extrusion drying equipment 03 by pipeline, and the extrusion drying equipment 03 can be used to extrude and dewater the waste to remove excess water and ensure the quality of subsequent fermentation;

[0045] The solid material discharge part on the extrusion drying device 03 is communicated with the fermentation device 04 through a conveying pipeline, and the extrusion drying device 03 conveys the dewatered garbage into the fermentation device 04 through the pipeline, so that the fermentation of the garbage can be carried out. At the same time, the liquid discharge part on the extrusion drying device 03 is communicated with the sewage treatment device 05 through a conveying pipeline, and the sewage obtained by extrusion can be conveyed into the sewage treatment device 05 through the pipeline, so that the sewage can be further treated and purified by using the sewage treatment device 05. Example 2

[0046] Please refer to Figures 2-13 , the extrusion drying device 03 in example 1 is explained in detail, and the specific structure of the extrusion drying device 03 is as follows:

[0047] The extrusion drying device 03 includes an outer tank body 1, a cylindrical core 2, a driving mechanism 4 and an extrusion dewatering group 3. The outer tank body 1 is supported and lifted by a support arranged below. A feeding cylinder 6 is connected to the top of the outer tank body 1. The feeding cylinder 6 has a feeding port 61 on one side of the top. The feeding port 61 serves as a feeding part and is connected to the crushing device 02. The organic garbage crushed by the crushing device 02 is conveyed into the feeding port 61 and then into the outer tank body 1 through the feeding cylinder 6, so as to realize the feeding of the organic garbage crushed material.

[0048] The cylindrical core 2 is installed in the outer tank body 1 and is rotatably connected to the outer tank body 1. The top end of the cylindrical core 2 extends to the upper side of the outer tank body 1. A plurality of extrusion dewatering groups 3 are arranged in an annular array on the outer circumferential side of the cylindrical core 2. The driving mechanism 4 is arranged on the top of the outer tank body 1 and is used to drive the rotation of the cylindrical core 2, so as to realize the position switching of the extrusion dewatering groups 3. That is, the driving mechanism 4 drives the rotation of the cylindrical core 2 in the outer tank body 1, which can synchronously drive the rotation of each extrusion dewatering group 3 around the axis of the cylindrical core 2 in the outer tank body 1.

[0049] Specifically, as shown in Figures 5-9 , the extrusion dewatering group 3 includes a fixed pressure plate 31 and a movable pressure plate 32. The fixed pressure plate 31 is fixed on the outer circumferential wall of the cylindrical core 2, and the movable pressure plate 32 is elastically connected to one side of the fixed pressure plate 31. That is, during the rotation of the cylindrical core 2 and each extrusion dewatering group 3 driven by the driving mechanism 4, when the movable pressure plate 32 is blocked, it can overcome the elastic force and move to the same side of the fixed pressure plate 31 in the same extrusion dewatering group 3. After the blockage disappears, the movable pressure plate 32 can be reset away from the fixed pressure plate 31.

[0050] The extrusion cavity 301 is formed between the dynamic pressure plate 32 and the fixed pressure plate 31 in the same extrusion dehydration group 3. When the driving mechanism 4 drives the cylindrical core 2 and the extrusion dehydration group 3 to rotate, the organic garbage in the feeding cylinder 6 can fall into the extrusion cavity 301 when the extrusion cavity 301 is aligned with the feeding cylinder 6, realizing garbage feeding. In addition, a plurality of leakage holes 11 are uniformly distributed on the bottom of the outer tank body 1, and a plurality of water outlet holes 321 are uniformly distributed on the dynamic pressure plate 32. The leakage holes 11 and the water outlet holes 321 are used for leaking the sewage extruded;

[0051] The outer tank body 1 is also provided with a resistance pushing mechanism 5. When the driving mechanism 4 drives the cylindrical core 2 and the extrusion dehydration group 3 to rotate, the resistance pushing mechanism 5 can push the dynamic pressure plate 32 to move close to the corresponding fixed pressure plate 31 when the extrusion dehydration group 3 passes through the resistance pushing mechanism 5, so that the space in the corresponding extrusion cavity 301 is reduced, and the garbage in the extrusion cavity 301 can be extruded and dehydrated, realizing the drying treatment of the garbage. The water body is directly discharged through the leakage hole 11, and the other part of the water body is discharged through the water outlet hole 321, and finally discharged through the leakage hole 11, thereby realizing the extrusion dehydration of the garbage.

[0052] As shown in Figure 13 , the outer tank body 1 is fixed with a water collecting tank 8 at the bottom. The water body discharged from the leakage hole 11 falls into the water collecting tank 8, and the water collecting tank 8 can collect the extruded water. At the same time, the water collecting tank 8 has a water outlet 81 at the bottom end. The water outlet 81 is connected to the sewage treatment equipment 05 as a liquid discharge part, and finally the water body in the water collecting tank 8 is discharged into the sewage treatment equipment 05 for sewage treatment;

[0053] Among them, the diameter of the water collecting tank 8 gradually decreases downward, that is, the diameter of the water collecting tank 8 becomes smaller and smaller downward, which is beneficial to guide the sewage to the water outlet 81, and thus facilitates the complete discharge of the sewage in the water collecting tank 8.

[0054] In addition, as shown in Figure 13 , the outer tank body 1 has a discharge port 102 at the bottom, and a guide chute 75 is arranged below the discharge port 102 at the bottom end of the outer tank body 1. The guide chute 75 is connected to the fermentation equipment 04 as a solid material discharge part. During the rotation of the cylindrical core 2 and the extrusion dehydration group 3 driven by the driving mechanism 4, when the garbage after extrusion dehydration carried by the fixed pressure plate 31 and the dynamic pressure plate 32 moves to the position aligned with the discharge port 102, the garbage falls into the guide chute 75 from the discharge port 102. The guide chute 75 is arranged obliquely, which can guide the garbage to the subsequent fermentation equipment 04 for fermentation.

[0055] As shown in Figure 5 , Figure 8 , and Figure 9As shown, the arc-shaped slide rod A 33 is located at the outer periphery of the arc-shaped slide rod B 34 and has the same curvature, which is a part of a circle. The movable pressure plate 32 has two slide holes 322. The movable pressure plate 32 is movably installed on the arc-shaped slide rod A 33 and the arc-shaped slide rod B 34 through the two slide holes 322. One of the slide holes 322 on the movable pressure plate 32 is matched with the arc-shaped slide rod A 33, and the other slide hole 322 on the movable pressure plate 32 is matched with the arc-shaped slide rod B 34. In this way, the movable pressure plate 32 has the ability to slide along the arc-shaped slide rod A 33 and the arc-shaped slide rod B 34.

[0056] In addition, the arc-shaped slide rod B 34 is externally sleeved with a spring 35. One end of the spring 35 is fixed to the movable pressure plate 32, and the other end is fixed to the corresponding fixed pressure plate 31, so that the movable pressure plate 32 and the corresponding fixed pressure plate 31 are elastically connected. When the contact pushing mechanism 5 blocks the movable pressure plate 32 from moving to the side of the fixed pressure plate 31, the spring 35 is compressed and stored at this time. When the contact pushing mechanism 5 cancels the blocking of the movable pressure plate 32, the spring 35 can push the movable pressure plate 32 to slide and reset under the elastic force of the spring 35, that is, to expand the space of the extrusion cavity 301, so as to leave space and make the extruded garbage fall down.

[0057] Secondly, as shown in the figure, Figure 9 The arc-shaped slide rod B 34 is externally sleeved with a corrugated telescopic sleeve 36 for covering the spring 35. One end of the corrugated telescopic sleeve 36 is fixed to the movable pressure plate 32, and the other end is fixed to the corresponding fixed pressure plate 31. The corrugated telescopic sleeve 36 is used for covering and protecting the spring 35, avoiding that the garbage splashes and is stuck on the spring 35 to affect the normal work of the spring 35. At the same time, the corrugated telescopic sleeve 36 has the ability of expansion and contraction and bending deformation to adapt to the position change of the movable pressure plate 32 when the movable pressure plate 32 moves.

[0058] Specifically, the outer tank body 1 is provided with a clearance groove 501 at the top. Each movable pressure plate 32 is fixed with a stop block 55 at the position corresponding to the clearance groove 501. During rotation, the stop block 55 at the top of the movable pressure plate 32 can pass through the clearance groove 501 in turn. The contact pushing mechanism 5 includes a telescopic cylinder A 52 and a baffle 54. The telescopic cylinder A 52 is vertically fixed to the side of the outer tank body 1 through a mounting seat 51. The telescopic cylinder A 52 is fixed with a suspension 53 at the telescopic end. The baffle 54 is fixed below the position corresponding to the clearance groove 501. The baffle 54 is correspondingly matched with the stop block 55.

[0059] Through the telescopic cylinder A52 pre-retract work, drive the suspension 53 and the baffle 54 down, the baffle 54 down through the let place slot 501, and reach the moving path of the stop block 55 in advance, when the dynamic pressure plate 32 top stop block 55 through let place slot 501, the baffle 54 block stop block 55, make dynamic pressure plate 32 stop moving, and then move to the side of the fixed pressure plate 31, realize extrusion dehydration;

[0060] Through the telescopic cylinder A52 pre-retract work, drive the suspension 53 and the baffle 54 down, the baffle 54 down through the let place slot 501, and reach the moving path of the stop block 55 in advance, when the dynamic pressure plate 32 top stop block 55 through let place slot 501, the baffle 54 block stop block 55, make dynamic pressure plate 32 stop moving, and then move to the side of the fixed pressure plate 31, realize extrusion dehydration;

[0061] Among them, as Figure 10 The let place slot 501 is provided with two groups, each group is provided with two, the baffle 54 is also provided with two groups, and each group is provided with two, and each dynamic pressure plate 32 top is provided with two stop blocks 55, when the baffle 54 in a group blocks the two stop blocks 55 at the same time, the corresponding two stop blocks 55 are blocked and contacted, the degree of stability is high, and the baffle 54 is provided with two groups, that is, in a rotating process of the cylindrical core 2, the garbage in the extrusion cavity 301 can be extruded and dehydrated twice in succession.

[0062] Specifically, after the first extrusion dehydration, the garbage in the extrusion cavity 301 is crushed, and the garbage is loose and falls to fill the space at the bottom of the extrusion cavity 301 under the action of gravity, and the garbage is dehydrated again in the second extrusion action, so that the garbage dehydration and drying treatment is more thorough.

[0063] As Figure 10 The driving mechanism 4 includes a driving motor A43 and a shaft coupling 44, and the top of the outer tank body 1 is fixed with a mounting table 42 through a pair of stands 41. The driving motor A43 is fixed on the mounting table 42, and the output shaft of the driving motor A43 is fixed and transmission connected with the top shaft end of the cylindrical core 2 through the shaft coupling 44. The mounting table 42 is used to fix the driving motor A43 above the outer tank body 1 through the stands 41. Through the working of the driving motor A43, the output shaft can drive the cylindrical core 2 to rotate under the transmission connection of the shaft coupling 44, thereby providing stable driving for the rotation of the cylindrical core 2. Embodiment 3

[0064] Please refer to Figure 5 , Figure 6 , Figure 8 and Figure 9 The difference between the embodiment and the embodiment 2 is that:

[0065] Under the elastic support of spring 35, the dynamic pressure plate 32 is in contact with the fixed pressure plate 31 in the adjacent extrusion and dewatering group 3, such as... Figure 14 As shown in the figure (the solid arrows in the figure indicate the direction of movement of the dynamic pressure plate 32 relative to the fixed pressure plate 31, and the dashed arrows indicate the direction of sewage extrusion), during the extrusion dewatering process, when the dynamic pressure plate 32 moves closer to the corresponding fixed pressure plate 31 to extrude the waste, the distance between the dynamic pressure plate 32 and the fixed pressure plate 31 in the adjacent extrusion dewatering group 3 increases, forming a water collection chamber 302. After the sewage flowing out of the water outlet 321 enters the water collection chamber 302, the large space inside the water collection chamber 302 ensures that the sewage can be discharged quickly, avoiding excessive accumulation of sewage.

[0066] Furthermore, during the dehydration process, some small-volume waste is squeezed into the water outlet 321, which can easily cause blockage. To solve this problem, the present invention makes the following improvements:

[0067] like Figure 6 As shown, push rods 311 are evenly distributed on one side of the pressure plate 31 near the pressure plate 31 in the adjacent extrusion dewatering group 3. When the spring 35 pushes the moving pressure plate 32 to fit with the pressure plate 31 in another extrusion dewatering group 3, each push rod 311 can be inserted into the outlet hole 321 one by one, thereby pushing the dirt accumulated in the outlet hole 321 back into the extrusion chamber 301, thus achieving the purpose of cleaning the dirt in the outlet hole 321. Each push rod 311 is conical, that is, the head diameter of the push rod 311 is small, so that it can smoothly enter the outlet hole 321 during the resetting of the moving pressure plate 32, avoiding obstruction and interference. Example 4

[0068] Please see Figure 11 The difference between this embodiment and embodiment 3 is as follows:

[0069] A top cover 62 is fixed to the top of the feeding cylinder 6, and a drive motor B63 is fixed on the top cover 62. An auger conveyor rod 64 is vertically installed inside the feeding cylinder 6. The top of the auger conveyor rod 64 is fixedly connected to the output shaft of the drive motor B63. The drive motor B63 drives the auger conveyor rod 64 to rotate inside the feeding cylinder 6, which can convey the garbage inside the feeding cylinder 6 downwards in a spiral. On the one hand, it can avoid excessive accumulation of garbage in the feeding cylinder 6 and blockage. On the other hand, it is convenient to control the amount of garbage fed into the compression chamber 301 in a single operation, and avoid excessive garbage feeding. Example 5

[0070] Please see Figure 13 The difference between this embodiment and embodiment 4 is that:

[0071] Specifically, the outer tank body 1 has a fitting groove 101 at the top corresponding to the position of the discharge port 102, and a pushing mechanism 7 is further arranged on the outer tank body 1, which is used to push the dewatered garbage in the extrusion cavity 301 out of the discharge port 102 downward, and the pushing mechanism 7 comprises a telescopic cylinder B72 and a pushing plate 74, a support 71 is fixed on the side of the outer tank body 1, the telescopic cylinder B72 is vertically fixed on the support 71, and the telescopic end of the telescopic cylinder B72 is connected with the pushing plate 74 through an L-shaped connecting arm 73, when the telescopic cylinder B72 is extended to the limit position, the pushing plate 74 is driven to move upward and fit into the fitting groove 101, so as to complement the fitting groove 101, and when the telescopic cylinder B72 is retracted, the pushing plate 74 is driven to move downward, so as to push the garbage in the corresponding extrusion cavity 301 to the guide chute 75.

[0072] When the dewatered and dried garbage in the extrusion cavity 301 is discharged downward to the guide chute 75, the telescopic cylinder B72 is retracted, and under the connection of the L-shaped connecting arm 73, the pushing plate 74 is pushed to move downward into the extrusion cavity 301, so as to push the garbage in the extrusion cavity 301 downward and discharge, which can speed up the garbage discharge and ensure that the garbage in the extrusion cavity 301 is discharged as much as possible; after the garbage is discharged, the telescopic cylinder B72 is extended, which can drive the pushing plate 74 to move upward and reset, and the pushing plate 74 is finally reset into the fitting groove 101, so as to avoid blocking and interference with the rotation of the fixed pressure plate 31 and the movable pressure plate 32, and it is worth noting that the telescopic cylinder A52 and the telescopic cylinder B72 in the application can be selected from electric cylinders, hydraulic cylinders or air cylinders.

[0073] In addition, the water collecting tank 8 is provided with a notch 82, and the guide chute 75 extends to the outside of the water collecting tank 8 through the notch 82, so as to transfer the dewatered and dried garbage to the outside.

[0074] The control mode of the application is automatically controlled by a controller, and the control circuit of the controller can be realized by simple programming by those skilled in the art, and the power supply also belongs to the common knowledge in the art, so the control mode and circuit connection of the application will not be explained in detail.

[0075] It is obvious for those skilled in the art that the application is not limited to the details of the above exemplary embodiments, and the application can be realized in other specific forms without departing from the spirit or essential characteristics of the application.
