Description

Technical Field

[0001] The invention belongs to the technical field of municipal sludge recovery and treatment, and in particular relates to a municipal sludge resource comprehensive utilization device. Background Art

[0002] At present, in the municipal field, the sludge produced is generally rich in a large amount of organic matter. If it is not effectively treated, the sludge will be directly piled up and discarded, which will not only cause environmental pollution, but also cause a large amount of resource waste. In order to avoid the waste of resources, the existing means is to improve the sludge and use it as a raw material to make permeable bricks for recycling. A large amount of organic matter in the sludge needs to be removed or calcined at high temperature so that the organic matter forms inorganic matter under high temperature environment, so as to ensure that the prepared permeable bricks have the expected characteristics and prevent the permeable bricks from being quickly destroyed by microorganisms. However, this process of utilizing municipal sludge not only fails to effectively utilize the organic matter in the sludge, but also increases the cost of preparing permeable bricks, which is contrary to the expectation of saving energy, reducing costs and increasing efficiency. It can be seen from this that there is an urgent need for a measure for the reuse of municipal sludge resources, which can effectively utilize the organic matter in the sludge, reduce the cost of recycling, and improve the utilization rate of the sludge.

DETAILED DESCRIPTION

[0040] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0041] The present invention discloses a device for comprehensive utilization of municipal sludge resources, such as Figure 1-21As shown, it includes a base 100, a vertical fermentation kettle 200, an annular mounting rail 300, a vertical adjustment mechanism 400, a circumferential running mechanism 500, a radial guide seat 600 and a universal material guide mechanism 700. Among them, the vertical fermentation kettle 200 is installed in the base 100, and the upper end of the vertical fermentation kettle 200 extends from the upper end of the base 100. The annular mounting rail 300 is installed at the upper end of the base 100, and the axis of the annular mounting rail 300 coincides with the axis of the vertical fermentation kettle 200. The lower end of the vertical adjustment mechanism 400 is connected to the circumferential running mechanism 500, and the circumferential running mechanism 500 is transmission-connected to the annular mounting rail 300; the radial guide seat 600 is transmission-connected to the vertical adjustment mechanism 400, and the universal material guide mechanism 700 is installed on the radial guide seat 600. The working principle and advantage of the present invention are: the present invention places the vertical fermentation kettle 200 below the ground through the base 100, thereby avoiding occupying too much ground space. Municipal sludge is put into the vertical fermentation kettle 200. Biomass materials such as straw, livestock excrement, etc. can be added into the vertical fermentation kettle 200 according to needs, and a fermentation agent is added. Afterwards, the circumferential running mechanism 500 is controlled to run circumferentially along the vertical fermentation kettle 200 on the annular mounting rail 300. During the running of the circumferential running mechanism 500, the universal material guide mechanism 700 is controlled to stir and mix the different raw materials in the vertical fermentation kettle 200, and the universal material guide mechanism 700 is controlled to move along the length direction of the radial guide seat 600, that is, along the radial direction of the vertical fermentation kettle 200. At the same time, the vertical adjustment mechanism 400 is controlled to move so that the universal material guide mechanism 700 is driven to move in the vertical direction through the radial guide seat 600, so that the universal material guide mechanism 700 continuously disturbs the sludge in the vertical fermentation kettle 200 circumferentially and at different depths, and regularly exchanges the sludge at different depths as needed, thereby achieving the effect of disturbing the vertical fermentation kettle 200 without dead angles, and realizing the purpose of sufficient mixing between different raw materials, thereby improving the sufficient fermentation. After the sludge in the vertical fermentation tank 200 is fermented and the fermented fertilizer is formed, the circumferential running mechanism 500, the vertical adjustment mechanism 400 and the universal guide mechanism 700 are controlled so that the fermented fertilizer in the vertical fermentation tank 200 is discharged from the vertical fermentation tank 200 by the universal guide mechanism 700 and transported by the fertilizer transport vehicle. In summary, the present invention ferments municipal sludge to efficiently decompose the organic matter therein and obtains fertilizer with extremely high fertility, thereby ensuring the full utilization of the organic matter in the sludge, reducing the recovery cost of the sludge, and improving the utilization rate of the sludge.

[0042] As a preferred embodiment of the present invention, Figure 1 , 2As shown, the base 100 includes a concrete base 101, a foundation assembly pit is constructed in the concrete base 101, and the foundation assembly pit extends downward from the upper end surface of the concrete base 101. The concrete base 101 is constructed below the ground surface, and the upper end of the concrete base 101 is flush with the upper end surface of the ground surface. The vertical fermentation kettle 200 of this embodiment is set in the foundation assembly pit, and an operation pit 102 is constructed in the concrete base 101 and below the vertical fermentation kettle 200, and the operation pit 102 is connected to the foundation assembly pit; an operation channel 103 is constructed in the concrete base 101 and between the operation pit 102 and the ground surface, and a climbing ladder 104 is installed at the vertical position of the operation channel 103, and a sealing cover 105 is installed at the upper end of the operation channel 103. When it is necessary to inspect, repair, etc. the lower part of the vertical fermentation kettle 200, the relevant personnel will open the sealing cover 105 and use the blower to blow air into the operating channel 103 to ensure that there is sufficient fresh air in the working pit 102; then, they will enter the working pit 102 through the operating channel 103 and inspect, repair, etc. the lower part of the vertical fermentation kettle 200.

[0043] As a preferred embodiment of the present invention, Figure 2-9 As shown, the vertical fermentation kettle 200 includes a vertical kettle body 201, an upper end cover 216 and a central tube. The interior of the vertical kettle body 201 is a fermentation chamber 202, a water seepage portion is configured at the lower end of the vertical kettle body 201, a first buckle edge 209 is formed at the upper end of the vertical kettle body 201, and a second buckle edge 225 is configured at the outer edge of the upper end cover 216. When the upper end cover 216 is buckled on the upper end of the vertical kettle body 201, the second buckle edge 225 is tightly sleeved outside the first buckle edge 209. In this embodiment, the lower end of the central tube extends into the lower part of the water seepage portion, and the upper end of the central tube extends out of the upper end cover 216 along the axis of the vertical kettle body 201. When the upper end cover 216 is opened, raw materials such as sludge can be added into the fermentation chamber 202, or fermented fertilizer in the fermentation chamber 202 can be discharged, or the raw materials in the fermentation chamber 202 can be disturbed by the universal material guide mechanism 700 to promote fermentation. During the fermentation process, the water that permeates downward and enters the water seepage part can connect the inlet end of the pump with the upper end of the central tube and perform a suction operation, thereby extracting the water in the water seepage part to avoid excessive water affecting the humidity of the fermentation environment and preventing the water from stinking. In this embodiment, an annular support edge 208 is constructed at the lower end of the vertical kettle body 201, and the annular support edge 208 is supported at the junction of the basic assembly pit and the working pit 102.

[0044] As a preferred embodiment of the present invention, Figure 4 , 5As shown in , 7, the water seepage part includes a mounting frame 214, a water seepage layer 213, an outer annular fixed plate 204, an annular transition plate 205 and a central bottom plate 206. The outer annular fixed plate 204, the annular transition plate 205 and the central bottom plate 206 are arranged in sequence from the outside to the inside, and the axes of the three coincide. Among them, the mounting frame 214 is fixedly installed at the lower part of the vertical kettle body 201, and the water seepage layer 213 is installed on the mounting frame 214. The outer annular fixed plate 204 and the central bottom plate 206 are constructed at the lower part of the vertical kettle body 201, and an annular assembly port 207 is formed between the outer annular fixed plate 204 and the central bottom plate 206. The annular transition plate 205 is detachably installed at the annular assembly port 207, and a water seepage cavity 212 is formed between the water seepage layer 213, the outer annular fixed plate 204, the annular transition plate 205 and the central bottom plate 206. The diameter of the water seepage cavity 212 gradually decreases downward in the vertical direction, so that the water in the fermentation cavity 202 penetrates into the water seepage cavity 212 through the water seepage layer 213, and gradually converges toward the central bottom plate 206, so as to quickly and fully extract the water in the water seepage cavity 212 through the central tube. When it is necessary to clean the water seepage cavity 212, the relevant personnel enter the working pit 102, remove the annular transition plate 205, and use cleaning tools to clean the water seepage cavity 212 through the annular assembly port 207.

[0045] As a preferred embodiment of the present invention, Figure 3 , 4As shown in Figures 6, 8 and 9, the central tube includes a first tube body 203 and a second tube body 217. A first connector 215 is configured at the upper end of the first tube body 203, and the lower end of the first tube body 203 passes through the mounting frame 214 and extends into the lower part of the water seepage cavity 212. A water suction nozzle 210 is configured at the lower end of the first tube body 203, and a filter cartridge 211 is sleeved on the water suction nozzle 210. After the water entering the water seepage cavity 212 is filtered by the filter cartridge 211, the water enters the first tube body 203 through the water suction nozzle 210. When the filter cartridge 211 is dirty and blocked, the filter cartridge 211 is cleaned at the same time during the cleaning of the water seepage cavity 212. The second tube body 217 of this embodiment is constructed at the center of the upper end cover 216. The second tube body 217 passes through the upper end cover 216. A first connecting sleeve 226 is constructed at the lower end of the second tube body 217. The first connecting sleeve 226 and the first connector 215 are plugged into each other and connect the first tube body 203 and the second tube body 217. A transfer pipe 218 is connected to the upper part of the second tube body 217. The transfer pipe 218 is connected to the inlet end of the water pump. In this embodiment, multiple guide sleeves 221 are spaced apart on the upper end cover 216. These guide sleeves 221 are divided into two groups. The multiple guide sleeves 221 in each group of guide sleeves 221 are evenly arranged along the circumference of the upper end cover 216, and the two groups of guide sleeves 221 are evenly arranged on the upper end cover 216. A connecting cap 222 is detachably mounted on the upper end of each guide sleeve 221, and an exhaust pipe 223 is constructed on the upper end cover 216, and a control valve 224 is mounted on the exhaust pipe 223. In this embodiment, when disturbing the material in the fermentation chamber 202, or performing operations such as feeding and discharging in the fermentation chamber 202, the upper end cover 216 is opened, and at this time, the second tube body 217 moves upward with the upper end cover 216 and is disengaged from the first tube body 203, and then the upper end cover 216 is placed beside the vertical kettle body 201. When the upper end cover 216 is buckled on the vertical kettle body 201, in order to ensure the adequacy of aerobic fermentation, it is necessary to timely introduce air into the raw materials in the fermentation chamber 202; specifically, each connection cap 222 is disassembled, and multiple ventilation pipes are respectively inserted into the fermentation chamber 202 through each guide sleeve 221, and each ventilation pipe is covered with air outlets. By ventilating these ventilation pipes, air enters the fermentation chamber 202 and is evenly dispersed to various areas in the fermentation chamber 202, thereby prompting aerobic bacteria to decompose the organic matter in the raw materials, and finally obtaining a fertilizer with extremely high fertility. The gas generated during the fermentation process of this embodiment gradually rises and enters the area between the vertical kettle body 201 and the upper end cover 216, and then is discharged by the exhaust pipe 223, and then this part of the gas is purified, and then directly discharged into the surrounding environment after purification. In this embodiment, water vapor can also be introduced into the fermentation chamber 202 through the ventilation pipe, thereby increasing the humidity of the fermentation chamber 202 to suit the life activities of aerobic bacteria.

[0046] As a preferred embodiment of the present invention, Figure 10-12 As shown, the inner annular rail body 302, the annular transition seat 301 and the outer annular transmission rail body 303 are arranged in sequence from the inside to the outside, and the axes of the three coincide. Among them, the lower end of the vertical adjustment mechanism 400 is slidably assembled on the inner annular rail body 302, and the annular transition seat 301 is detachably fixed on the upper end surface of the base seat 100. Fig.14 As shown, the circumferential running mechanism 500 includes a first drive motor 501 and a running gear 502. The first drive motor 501 is installed at the lower part of the vertical adjustment mechanism 400. The running gear 502 is coaxially mounted on the output shaft of the first drive motor 501, and the running gear 502 is meshed with the outer annular transmission rail body 303. In this embodiment, the running gear 502 is driven to rotate by the first drive motor 501. During the rotation of the running gear 502, the running gear 502 and the outer annular transmission rail body 303 are mutually transmitted, thereby driving the vertical adjustment mechanism 400 to slide along the inner annular rail body 302, so that the universal material guide mechanism 700 disturbs the raw materials such as sludge in the fermentation chamber 202.

[0047] As a preferred embodiment of the present invention, Fig.13 , 14As shown, the vertical adjustment mechanism 400 includes a vertical guide seat 401, a lower sliding seat 402, an upper fixed seat 403, a vertical transmission screw 404, a second drive motor 405, a transmission seat 406 and an adjustment seat 407. The lower sliding seat 402 and the upper fixed seat 403 are respectively constructed at the vertical ends of the vertical guide seat 401, the second drive motor 405 is fixedly mounted on the upper fixed seat 403, the output shaft of the second drive motor 405 is coaxially connected with the vertical transmission screw 404, the lower end of the vertical transmission screw 404 is rotatably connected with the lower sliding seat 402, and the lower sliding seat 402 is slidably connected with the annular mounting rail 300. The transmission seat 406 of the present embodiment is slidably connected to the vertical guide seat 401. The transmission seat 406 is threadedly connected to the vertical transmission screw 404. The transmission seat 406 is pivotally connected to the adjustment seat 407 through a vertical pivot shaft 408. A plurality of limiting holes 409 are respectively provided on the transmission seat 406 and the adjustment seat 407. The limiting holes 409 on the transmission seat 406 are evenly arranged along the circumference of the vertical pivot shaft 408, and the limiting holes 409 on the adjustment seat 407 are also evenly arranged along the circumference of the vertical pivot shaft 408.
