Description

Technical Field

[0001] The invention relates to the technical field of dried sludge unloading, and in particular to a discharging dispersion system and method for loading dried sludge onto trucks. Background Art

[0002] In sludge treatment, for liquid sludge with a moisture content of more than 99%, concentration, dehydration and drying processes are usually carried out to convert the liquid sludge into granular or powdery dried sludge with a moisture content between 30-40%. Due to its loose and dispersed physical properties, the dried sludge is very likely to cause dust problems during subsequent transportation and unloading. It not only pollutes the working environment, but also poses a serious threat to the respiratory health of on-site operators. In the selection of unloading equipment, traditional telescopic bag unloaders are generally used for auxiliary unloading. However, it is the looseness of the dried sludge that makes it impossible to effectively solve the sludge dust problem when unloading to the receiving port of the transport vehicle through the telescopic bag. In addition, after the dried sludge is unloaded to the vehicle, it will naturally accumulate into a small hill in the storage space below the receiving port, which causes the dried sludge to be unevenly distributed in the storage space and affects the efficiency of subsequent loading and unloading operations. In order to flatten the small hills of accumulated sludge, inertia is used to start the vehicle to move back and forth quickly and brake to flatten the hills, and then dock the unloader again for loading. Or people can directly use long poles to dig materials at the receiving port to flatten the hills. The above process is not only time-consuming and labor-intensive, reducing the overall operating efficiency, but also has certain safety hazards and serious dust. Therefore, how to develop a discharging and dispersing system for loading dried sludge, which can effectively disperse the sludge, control dust and promote the uniform distribution of dried sludge when loading bulk materials, is an urgent problem that needs to be solved.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] like Figure 1 As shown, a discharging and unloading system for loading dried sludge is mainly composed of a storage device 2, a conveying device 3 and a discharging device 1 arranged in series, which are generally arranged vertically together, the storage device 2 is located at the upper part of the system, the conveying device 3 is located below the storage device 2, the side of the conveying device 3 is connected to the upper part of the discharging device 1, and the lower part of the discharging device 1 is connected to the transport vehicle 5, and a staggered arrangement is formed between the storage device 2 and the discharging device 1, which not only optimizes space utilization, but also promotes smooth flow of materials.

[0031] Next refer to Figure 1 and Fig. 9 The storage device 2 is used to store dried sludge and has an inlet 201 for receiving dried sludge and an outlet 202 for discharging dried sludge. The inlet 201 is located at the top of the storage device 2 and is used to receive dried sludge from an upstream process, such as a paddle dryer, a direct low-temperature dryer, etc. The outlet 202 is located at the bottom of the storage device 2 and corresponds to the conveying device 3 to ensure that the sludge can smoothly fall into the conveying device 3. A gate valve 4 is also provided between the storage device 2 and the conveying device 3 to control the discharge amount of dried sludge from the storage device 2 falling into the conveying device 3 to ensure the stability and continuity of the conveying process.

[0032] Next refer to Figure 1 and Fig.10 The conveying device 3 is located between the storage device 2 and the discharge device 1, and includes a conveying shell 301 and at least one conveying screw arranged in the conveying shell 301. The conveying shell 301 has a receiving port 301a for receiving dried sludge and a discharge port 301b for discharging dried sludge. The receiving port 301a is arranged at the upper part of the conveying shell 301. The receiving port 301a of the conveying device 3 is located below and corresponding to the outlet 202 of the storage device 2, and the discharge port 301b is arranged on the end wall of the conveying shell 301, that is, on the end wall of the conveying shell 301 away from the receiving port 301a. The conveying screw is used to control the feeding amount of dried sludge to the discharge device 1, wherein the number of the conveying screws is two, and the two conveying screws are arranged side by side in the conveying shell 301. The dust problem that may be generated when the dried sludge of the storage device 2 directly falls into the discharge device 1 is effectively avoided by horizontal conveying. At the same time, the conveying device 3 also plays a buffering role.

[0033] like Figure 2-4 As shown in Figures 6 and 7, the unloading device 1 includes a unloading cylinder 101, which is generally arranged vertically. The unloading cylinder 101 has a feed port 101a for receiving dried sludge and a discharge port 101b for discharging dried sludge. The feed port 101a of the unloading device 1 is at approximately the same height as or below the discharge port 301b of the conveying device 3, that is, the feed port 101a can be set on the side wall or top wall of the unloading cylinder 101, and the discharge port 101b is located at the bottom of the unloading cylinder 101, which is used to dock with the docking port 501 of the transport vehicle 5. Among them, the unloading cylinder 101 has a dispersion component 103 inside, which is configured to disperse the dried sludge when it is discharged from the discharge port 101b, so as to avoid the local accumulation and blockage of the sludge during the unloading process, and further improve the efficiency of loading.

[0034] Next refer to Figure 5, which shows the internal structure of the discharge device 1. A dust removal cylinder 102 is vertically arranged inside the discharge cylinder 101 to divide the space inside the discharge cylinder 101 into a discharge channel 102a and a dust removal channel 102b. The discharge channel 102a and the dust removal channel 102b form an inside-outside layout. The upper and lower ends of the dust removal cylinder 102 are open and are respectively connected to the feed port 101a and the discharge port 101b, that is, the dried sludge enters the upper end of the discharge channel 102a from the feed port 101a, and is then discharged from the lower end of the discharge channel 102a and the discharge port 101b, while the lower end of the discharge channel 102a is connected to the lower end of the dust removal channel 102b. A plurality of air vents 102c are provided on the circumferential wall of the dust removal cylinder 102, which are used to guide the sludge dust in the discharge channel 102a to the dust removal channel 102b. The upper portion of the discharge cylinder 101 is provided with at least one dust removal port 101c, which is used to discharge the sludge dust in the dust removal channel 102b. There are three dust removal ports 101c, which are arranged on the outer wall of the upper portion of the discharge cylinder 101 at certain intervals. An exhaust fan is connected to the outside of the dust removal port 101c through a pipeline. When the dried sludge falls from the discharge channel 102a, the exhaust fan is started, and the sludge dust generated during the unloading process is first sucked from the air vents 102c to the dust removal channel 102b, and then the sludge dust is discharged from the dust removal port 101c driven by the gas, thereby effectively avoiding the dust problem caused by the overflow of sludge dust from the discharge port 101b. The dust removal cylinder 102 has a conical section and a cylindrical section arranged up and down, the upper end of the conical section is fixed to the circumferential wall of the upper part of the discharge cylinder 101, the lower end of the conical section is annularly inclined from the circumferential wall of the discharge cylinder 101 to the central axis and fixed to the upper end of the cylindrical section, the lower end of the cylindrical section extends downward along the height direction of the discharge cylinder 101 and is located near the discharge port 101b, and a plurality of vents 102c are circumferentially arranged on the outer wall of the cylindrical section, wherein a guide pipe is also provided at the vent 102c, and the outlet end of the guide pipe is inclined toward the dust removal port 101c, which is more conducive to the sludge dust in the discharge channel 102a being guided upward to the dust removal port 101c through the vent 102c and the guide pipe for discharge. The dispersion assembly 103 is located in the discharge channel 102a to disperse the dried sludge in the discharge channel 102a into the storage space of the transport vehicle 5.

[0035] Next reference Figure 5 and Figure 7, which shows a preferred embodiment of the dispersion component 103, the dispersion component 103 includes a sleeve 103a and a rod body 103b slidably arranged in the sleeve 103a, the upper and lower ends of the sleeve 103a are open, and it is a roughly cylindrical structure, and the shape of the rod body 103b matches the shape of the sleeve 103a, and the outer diameter of the rod body 103b is less than or equal to the inner diameter of the sleeve 103a, so that the rod body 103b can be inserted into the sleeve 103a, wherein the inner wall of the sleeve 103a has a groove along its length direction, and the outer wall of the rod body 103b is correspondingly provided with a protrusion that matches the groove, and the protrusion and the groove are used to limit the sliding trajectory of the rod body 103b inside the sleeve 103a. Among them, the upper end of the sleeve 103a is fixed to the upper part of the unloading cylinder 101, and the upper part of the unloading cylinder 101 is provided with a support 110. The two ends of the support 110 are respectively fixed on the inner wall of the unloading cylinder 101. The support 110 is a hollow sealing structure with a triangular cross-section. The upper end of the sleeve 103a is fixed to the inside of the support 110 through a flange to position the sleeve 103a and the rod body 103b on the central axis of the unloading cylinder 101. An inspection port 110a is provided on the outer wall of the support 110. A first driving assembly 104 is provided at the upper end of the sleeve 103a. The first driving assembly 104 is located inside the support 110 and is used to drive the sleeve 103a to rotate and drive the rod body 103b to rotate synchronously. The first driving assembly 104 includes a motor 104a and a transmission rod 104b arranged at one end of the motor 104a. The motor 104a is fixed on the outer wall of the unloading barrel 101, and the transmission rod 104b is arranged parallel to the inside of the support 110 and is perpendicular to the sleeve 103a. One end of the transmission rod 104b has a first bevel gear 104c, and the upper end of the sleeve 103a has a second bevel gear 103a1, and the second bevel gear 103a1 is meshed with the first bevel gear 104c.

[0036] Continue to refer to Figure 7The upper end of the rod body 103b is provided with a second driving component 105 for driving the rod body 103b to slide in the sleeve 103a, and the lower end of the rod body 103b is provided with a dispersion cover 103c for dispersing the dried sludge. The second driving component 105 includes a roller 105a and a wire rope 105b. The roller 105a is fixed in the support 110 through a connecting rod, and the wire rope 105b is hung on the roller 105a. One end of the wire rope 105b is fixed to the upper end of the rod body 103b, and the other end of the wire rope 105b extends to the outside of the unloading cylinder 101 and is connected to the power input component, which is a winch. When the sludge dispersion operation is implemented, the winch drives the wire rope 105b, and the roller 105a also rotates, and drives the rod body 103b to slide downward in the sleeve 103a until the dispersion cover 103c is located below the discharge port 101b and extends into the storage space of the transport vehicle 5 and stops. When the discharge stops, it is only necessary to reverse the operation and raise the dispersion cover 103c to the inside of the discharge cylinder 101. Among them, the cross section of the dispersion cover 103c is an inverted cone, and the dried sludge falling from the discharge port 101b contacts the inverted cone slope formed on the upper surface of the dispersion cover 103c. The sludge is dispersed outward and evenly distributed in the storage space of the transport vehicle 5 through the rotating centrifugal force of the dispersion cover 103c. When the motor 104a is started and drives the transmission rod 104b to rotate, the second bevel gear 103a1 meshes with the first bevel gear 104c, driving the sleeve 103a to rotate. Due to the cooperation between the slot and the protrusion between the sleeve 103a and the rod body 103b, the rod body 103b also rotates, thereby driving the dispersion cover 103c to rotate, thereby achieving uniform dispersion of the sludge.

[0037] like Figure 8 As shown, in another embodiment, a plurality of guide plates 103c1 are provided in the circumferential direction of the outer surface of the dispersion cover 103c, and the plurality of guide plates 103c1 are arranged at a certain interval on the inverted conical slope of the dispersion cover 103c, and the plurality of guide plates 103c1 are deflected to the left or right at a certain angle in the same direction on the inverted conical slope to form a curved flow channel between two adjacent guide plates 103c1, which not only enhances the power of the dried sludge to disperse outward, but also ensures the effective and uniform distribution of the sludge during the dispersion process, so as to improve the dispersion efficiency and optimize the sludge flow path. A reinforcing ring rib 103c2 is also provided at the bottom of the dispersion cover 103c to improve the stability of the rotation of the dispersion cover 103c.

[0038] In another embodiment, a plurality of connecting ports are arranged in the middle circumferential direction of the dispersion hood 103c, and the connecting ports are used to drop the dried sludge into the space below the dispersion hood 103c. That is to say, when the dried sludge falls into the dispersion hood 103c, a portion of the sludge can directly fall into the space below the dispersion hood 103c through the connecting ports, while the other portion of the sludge will be dispersed to the external area under the action of the centrifugal force generated by the high-speed rotation of the dispersion hood 103c, thereby further improving the uniformity of the material in the storage space.

[0039] Continue to refer to Figure 2 and Figure 4 , a bracket 107 and a camera 108 arranged at one end of the bracket 107 are arranged on the outer wall of the discharge cylinder 101, and the camera 108 faces the lower part of the discharge port 101b, and is used to monitor the discharge safety of the dried sludge and identify the position of the docking port 501 of the transport vehicle 5. When unloading and loading, the camera 108 will capture the image of the transport vehicle 5, and transmit the image to the control system for analysis and processing, and then identify the position and shape of the docking port 501 of the transport vehicle 5. Then, according to the visual recognition result, the discharge port 101b of the unloading device 1 is controlled to dock with the docking port 501 of the transport vehicle 5, and then the dispersion cover 103c of the dispersion component 103 is controlled to extend into the storage space of the transport vehicle 5, and finally the bulk dried sludge is unloaded and dispersed therein.

[0040] like Figure 5 As shown, the lower part of the unloading cylinder 101 has a sensor 109 for monitoring the material level. The sensor 109 is a photoelectric sensor that can monitor the material level of the internal storage space of the transport vehicle 5 in real time. The photoelectric sensor determines the material level of the dried sludge by emitting a light beam and receiving the signal reflected or transmitted back. During the unloading process, as the dried sludge continues to fall into the transport vehicle 5, the photoelectric sensor can respond to the changes in the material level and convert these changes into electrical signals for transmission. The unloading and loading of the dried sludge is remotely controlled by the camera 108 and the sensor 109 to achieve unmanned operation.

[0041] Among them, the unloading cylinder 101 includes a rigid cylinder, a flexible cylinder and a docking cone arranged in sequence from top to bottom. The rigid cylinder serves as the supporting structure of the unloading cylinder 101, and one side wall of which is fixed to the end wall of the conveying shell 301. The feed port 101a and the dust removal port 101c are both located on the outer wall of the rigid cylinder. The two ends of the support 110 are respectively fixed on the inner wall of the rigid cylinder. The flexible cylinder is a telescopic cloth bag. The telescopic cloth bag has multiple fixing rings arranged at certain intervals along its height direction. The multiple fixing rings are connected in series through flexible materials, and the overall height is adjusted by folding and telescoping. The unloading port 101b is located at the bottom of the docking cone, and the docking cone cooperates with the docking port 501 of the transport vehicle 5, so that the docking cone can be matched with the docking port 501 of the transport vehicle 5 at different heights.

[0042] like Figure 2-5 As shown, a lifting assembly 106 is provided on the outside of the discharge cylinder 101, and the lifting assembly 106 includes a first annular plate 106a and a second annular plate 106b arranged up and down, the first annular plate 106a is fixed to the upper part of the discharge cylinder 101, and the second annular plate 106b is fixed to the lower part of the discharge cylinder 101, and a plurality of telescopic rods 106c for adjusting the height of the discharge cylinder 101 are provided between the first annular plate 106a and the second annular plate 106b, wherein the lifting assembly 106 is located outside the flexible cylinder to control the folding and telescoping of the flexible cylinder, specifically, the first annular plate 106a is fixed to the upper part of the flexible cylinder, the second annular plate 106b is fixed to the lower part of the flexible cylinder, and the first annular plate 106a and the second annular plate 106b are fixed to the lower part of the flexible cylinder. A plurality of telescopic rods 106c are arranged at certain intervals around the outside of the flexible cylinder, and the upper and lower ends of the telescopic rods 106c are respectively connected to the first annular plate 106a and the second annular plate 106b by bolts, and a cylinder 106d is also arranged between the first annular plate 106a and the second annular plate 106b, and the upper and lower ends of the cylinder 106d are respectively connected to the first annular plate 106a and the second annular plate 106b, which serves as a power source for the lifting assembly 106 and can drive the telescopic rod 106c to perform up and down telescopic movements, and the distance between the first annular plate 106a and the second annular plate 106b is adjusted by the cylinder 106d, thereby realizing the folding and telescoping of the flexible cylinder, which is conducive to achieving accurate docking between the discharge port 101b and the docking port 501.

[0043] A method for utilizing a discharging and dispersing system for loading dried sludge onto a truck, the method comprising: The storage device 2 is started to receive the dried sludge from the inlet 201 and store it in the internal space. The dried sludge with a moisture content of 30-40% enters the storage device 2 from the inlet 201 for temporary storage. The discharge amount is controlled by the gate valve 4 at the outlet 202.

[0044] When loading is required, the lifting component 106 is first actuated, and the position of the docking port 501 of the transport vehicle 5 is automatically identified by the camera 108, and then the height of the discharge cylinder 101 is adjusted so that the discharge port 101b is docked with the docking port 501 of the transport vehicle 5, and then the gate valve 4 is opened, and the conveying screw of the conveying device 3 is actuated to control the movement of the dried sludge discharged through the outlet 202 of the storage device 2 and falling into the conveying shell 301 by its own weight to the discharge port 301b formed on the end wall of the conveying shell 301. Specifically, the dried sludge enters the interior of the conveying shell 301 through the outlet 202 and the receiving port 301a, and is driven by the two conveying screws to be conveyed to the discharge port 301b and discharged.

[0045] The dispersing assembly 103 of the unloading device 1 is actuated, and the dried sludge falls into the unloading cylinder 101 through the discharge port 301b and the receiving port 301a. The dried sludge discharged from the discharge port 101b is dispersed by the dispersing assembly 103 so as to be evenly distributed in the storage space of the transport vehicle 5. Specifically, the dried sludge falls from the discharge port 301b and the receiving port 301a into the unloading channel 102a. During the falling process, the exhaust fan is started, and the sludge dust enters the dust removal channel 102b through the vents 102c on the circumferential wall of the dust removal cylinder 102, and is discharged through the dust removal port 101c, so that the sludge dust is separated from the dried sludge. The dried sludge continues to fall and is discharged from the discharge port 101b. At this time, the dispersion assembly 103 starts to work, driving the rod body 103b to slide downward in the sleeve 103a, and the dispersion cover 103c at the lower end of the rod body 103b moves to below the discharge port 101b and extends into the storage space of the transport vehicle 5. The motor 104a is then started, and the sleeve 103a is driven to rotate through the transmission rod 104b, the first bevel gear 104c and the second bevel gear 103a1, thereby driving the rod body 103b and the dispersion cover 103c to rotate, and the dried sludge will be evenly dispersed into the storage space under the action of the centrifugal force generated by the high-speed rotation of the dispersion cover 103c.

[0046] In general, the system of the present invention realizes efficient unloading of dried sludge from storage to loading through the coordinated work of a storage device, a conveying device and a unloading device. The dispersion component in the unloading device effectively disperses the dried sludge through a combination of rotation and telescopic action, avoids local accumulation and agglomeration of sludge in the transport vehicle, and improves the uniform distribution of sludge. The dust removal cylinder arranged in the unloading cylinder effectively removes sludge dust, discharges the dust to the dust removal channel through the vent, and discharges it through the dust removal port to prevent dust from overflowing from the unloading port, thereby reducing dust pollution to the environment and operators. The camera monitors the position of the transport vehicle docking interface below the unloading port in real time to ensure the accuracy and safety of the unloading process. The material level sensor can monitor the material level of the internal storage space of the transport vehicle in real time, and realize unmanned unloading operation through the camera and sensor.

[0047] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
