In addition, terms such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] As Figures 1-4 shown, a sludge drying treatment device according to a preferred embodiment of the present utility model includes a storage bin mechanism 1, a conveying mechanism 2 and a drying mechanism 3;

[0027] The storage bin mechanism 1 includes a storage bin 11, an arch-breaking carriage 12, and a gas detector 13. The storage bin 11 includes a bin body 111 and a cover plate 112. The cover plate 112 covers the top of the bin body 111. The arch-breaking carriage 12 is arranged inside the bin body 111. A first odor extraction port 1121 is formed on the cover plate 112. The gas detector 13 is arranged on the cover plate 112 and is used to detect the gas content inside the storage bin 11. The bottom of the bin body 111 has an open end.

[0028] The conveying mechanism 2 includes a conveying bin 21, a spiral pushing assembly 22, and a flap valve 23. The conveying bin 21 is arranged at the bottom of the bin body 111. The top of one end of the conveying bin 21 is communicated with the bin body 111. A second odor extraction port 211 and a feeding port are successively formed at the top and bottom of the other end of the conveying bin 21. The spiral pushing assembly 22 is arranged inside the conveying bin 21. The flap valve 23 is arranged at the feeding port.

[0029] The drying mechanism 3 is provided with a feed inlet 31, a discharge outlet 32, and an exhaust gas discharge port 33. The feed inlet 31 is communicated with the feeding port.

[0030] Specifically, the storage bin mechanism 1, the conveying mechanism 2, and the drying mechanism 3 are connected in sequence. The sludge is stored inside the bin body 111 of the storage bin 11. The top of the bin body 111 is covered with a cover plate 112 to seal the storage bin 11 and ensure that the harmful gases generated by the stored sludge are not easily spilled. The gas detector 13 is arranged on the cover plate 112 at the top of the bin body 111. Since the gas usually floats at the top of the bin body 111, it can detect the content of harmful gases inside the bin body 111 to facilitate the user to understand the gas content inside the bin body 111. The first odor extraction port 1121 is set to start regularly or remain in the start state and is used to extract the gas inside the bin body 111 to the harmful gas treatment device. The harmful gas treatment device passes through the waste gas treatment equipment, and the treated gas can be discharged only after being detected to meet the emission standards, avoiding environmental pollution caused by the harmful gases generated by the sludge. The conveying mechanism 2 is arranged at the bottom of the bin body 111. The conveying bin 21 is communicated with the bin body 111 through the open end, and a valve is provided at the open end to control the opening and closing of the open end. An arch-breaking carriage for pushing the sludge is also arranged inside the bin body 111. When the valve is opened, the sludge stored inside the bin body 111 falls into the conveying bin 21 under the action of gravity. At the same time, the arch-breaking carriage 12 starts to push the sludge downward to accelerate the speed of the sludge entering the conveying bin 21 and improve the conveying efficiency.

[0031] After the sludge enters the conveying bin 21, it is pushed by the spiral pushing assembly 22 to the other end of the conveying bin 21 and discharged from the feeding port. A flap valve 23 is arranged at the feeding port to control the opening and closing of the feeding port. A second odor extraction port 211 is arranged on the conveying bin 21 to extract the gas overflowing during the conveying of the sludge to the harmful gas treatment device. After being treated to meet the emission standards, it is discharged to avoid environmental pollution caused by the overflow of harmful gases.

[0032] The feed inlet 31 of the drying mechanism 3 is in communication with the feeding port of the conveying bin 21. The conveying mechanism 2 conveys the sludge into the drying mechanism 3. The drying mechanism 3 dries and removes water from the incoming sludge. After the drying treatment, the sludge is discharged from the discharge port 32 to obtain sludge with a lower water content, which can be subjected to subsequent treatment. The harmful gases generated by the sludge during the drying process are discharged from the tail gas discharge port 33 and treated by a harmful gas treatment device to avoid environmental pollution.

[0033] In addition, the interiors of the storage bin mechanism 1, the conveying mechanism 2, and the drying mechanism 3 are all subjected to anti-corrosion treatments such as painting or making with anti-corrosion materials to prevent the storage bin mechanism 1, the conveying mechanism 2, and the drying mechanism 3 from being corroded by the corrosive substances contained in the sludge and to improve the service life.

[0034] Through the above-mentioned sequentially arranged storage bin mechanism 1, conveying mechanism 2, and drying mechanism 3, the sludge can be stored, conveyed, and dried. The connections between the mechanisms are tight. The sludge conveying efficiency is improved by the arch-breaking carriage 12 and the conveying mechanism 2, and thus the sludge drying treatment efficiency is improved. By providing odor extraction ports and tail gas discharge ports on each mechanism, the harmful gases generated by the sludge during the drying process are uniformly treated and then discharged to avoid environmental pollution.

[0035] Preferably, the storage bin mechanism 1 includes a level gauge 14 for detecting the material level in the bin 11. The level gauge 14 is installed on the cover plate 112 and is electrically connected to the screw pushing assembly 22.

[0036] Specifically, the level gauge 14 is provided on the cover plate 112 and is electrically connected to the screw pushing assembly 22. The level gauge 14 can detect the sludge storage amount in the bin body 111. When the sludge storage amount in the bin body 111 reaches a certain amount, the level gauge 14 detects that the material level of the sludge exceeds a certain value, and the level gauge 14 sends a signal to connect the bin body 111 with the conveying bin 21. The sludge enters the conveying bin through the open port at the bottom of the bin body 111, and the screw pushing assembly 22 conveys the sludge to the drying mechanism 3 for treatment to reduce the sludge storage amount inside the bin body 111 and avoid excessive sludge storage in the bin body 111 exceeding its storage capacity.

[0037] Preferably, an opening is provided on the cover plate 112. A grille plate and a sliding door are provided at the opening. The sliding door is arranged above the grille plate.

[0038] Specifically, an opening is formed in the cover plate 112 for pouring sludge for storage; the length and width of the grids of the grid plate are not greater than 250 mm to prevent large-sized sundries or on-site workers from falling into the bin body 111. The grid plate is coated with a corrosion-resistant material to ensure that the grid plate is not easily corroded by the sludge remaining at the opening, and an anti-wear pad with a relatively low hardness is provided at the edge of the grid plate to prevent the grid plate from being worn; the lifting door occupies a relatively small space, can save the space inside the bin body 111, and improve the sludge storage effect.

[0039] Preferably, a retaining wall is provided along the outer periphery of the cover plate 112.

[0040] Specifically, a fence is provided on the outer periphery of the cover plate 112, which can provide shielding during vehicle unloading to prevent sludge from splashing out, and it is also convenient to clean and collect the sludge splashed on the fence.

[0041] Preferably, the spiral pushing assembly 22 includes a pair of spirally advancing devices arranged in parallel. The spirally advancing device includes: a screw rod 221 and multiple groups of blade groups 222. The multiple groups of blade groups 222 are arranged at intervals along the axial direction of the screw rod 221, and each group of blade groups 222 includes at least two blades arranged at intervals circumferentially along the outer periphery of the screw rod 221.

[0042] Specifically, the two screw rods 221 are arranged in parallel, and the length direction of the screw rod 221 is the same as the length direction of the conveying bin 21. The blades are arranged at intervals along the axial direction of the screw rod 221 and extend along the screw rod 221 towards the end close to the flap valve 23. The blades form an angle with the screw rod 221. After the sludge enters the conveying bin 21, it contacts the screw rod 221 and the blade group 222. The blade group 222 contacts the sludge during rotation and pushes the sludge towards the end of the conveying bin 21 where the flap valve 23 is provided, realizing sludge conveyance. By providing two parallel spiral pushing assemblies 22, the sludge conveyance efficiency can be improved.

[0043] Furthermore, the blade groups 222 of the two spirally advancing devices are staggered in the axial direction.

[0044] Specifically, the blades on the two screw rods 221 are staggered. When conveying sludge, the two screw rods 221 rotate at the same speed to ensure that there is no collision between the blades on the screw rod 221 during rotation, which may cause component damage, and the interval between the blades is small, which can fully contact the sludge and improve the sludge conveyance efficiency; during the sludge conveyance process, the amount of conveyed sludge can be adjusted by adjusting the rotation speed of the screw rod or the shaft diameter of the blade to facilitate adjustment according to the overall usage of the device.

[0045] Preferably, the drying mechanism 3 is a disk dryer. The drying mechanism 3 includes a housing 34 and a disk heat exchange and pushing assembly 35 disposed inside the housing 34. The disk heat exchange and pushing assembly 35 includes a plurality of heat exchange disks 351 arranged at intervals in sequence along the transverse direction. The feed inlet 31, the discharge outlet 32, and the tail gas discharge port 33 are all opened on the housing 34.

[0046] Specifically, the feed inlet 31 and the discharge outlet 32 are respectively disposed at both ends of the housing 34. The disk heat exchange and pushing assembly 35 includes a disk heating structure and a pushing structure. After the sludge enters the interior of the housing 34 through the feed inlet 31, it falls onto the pushing structure. The pushing structure can be a conveyor belt or other propellers. The pushing structure drives the sludge to slowly move in the direction of the discharge outlet 32. The disk heating structure contacts the sludge during the conveying process, stirs and heats the sludge to achieve sludge dewatering and drying. The disk heating structure includes a rotating shaft arranged along the length direction of the pushing structure and heat exchange disks 351 spaced apart on the rotating shaft. The heat exchange disks 351 are perpendicular to the rotating shaft. The rotating shaft and the heat exchange disks 351 are hollow structures and communicate with each other. When drying the sludge, high-temperature steam is introduced into one end of the rotating shaft, so that the temperatures of the rotating shaft and the heat exchange disks 351 increase. Both sides of the heat exchange disks 351 can heat the sludge, improving the heating efficiency. The rotating shaft drives the heat exchange disks 351 to rotate, stirs the sludge and heats it to fully dry the sludge. When the sludge is pushed by the pushing structure to the discharge outlet 32, the sludge is fully dried and discharged from the discharge outlet 32. The tail gas discharge port 33 is arranged on the housing 34. Air is pumped at the tail gas discharge port 33, creating a negative pressure inside the drying mechanism 3. The harmful gases generated during the sludge stirring and heating process are extracted through the tail gas discharge port 33 for treatment, and the odor is discharged after treatment.

[0047] During sludge treatment, the rotational speed of the heat exchange disks 351 is relatively low, enabling the sludge in contact with them to be fully heated, while reducing the dust and odor generated during the stirring process. The sludge is transported forward by the pushing structure, and the heat exchange disks 351 do not need to provide the thrust to push the sludge, effectively extending the service life of the heat exchange disks 351.

[0048] Furthermore, a plurality of rotors 3511 that rotate with the heat exchange disks 351 are provided on the heat exchange disks 351. The rotors 3511 are plate-shaped structures and are spaced apart on the heat exchange disks 351 to increase the contact area between the heat exchange disks 351 and the sludge, making the stirring and heating more sufficient.

[0049] In addition, a condenser is provided between the tail gas discharge port 33 and the harmful gas treatment device. The gas generated by the heated sludge enters the condenser after dust removal. The water vapor in the gas condenses into liquid sewage, which is collected in the waste water tank and waits for subsequent sewage treatment. The remaining non-condensable harmful gases are introduced into the harmful gas treatment device for treatment and are discharged after meeting the standards.

[0050] Preferably, the outer shell 34 includes a dome 341 and a heat exchange chamber 342. The dome 341 is installed on the top of the heat exchange chamber 342 and is in communication with the heat exchange chamber 342. The feed inlet 31 and the tail gas discharge port 33 are provided on the top of the dome 341.

[0051] Specifically, the dome 341 is in communication with the heat exchange chamber 342, and the dome 341 is provided on the top of the heat exchange chamber 342 to provide a relatively large space for sludge drying, so as to ensure that when the sludge conveying amount of the conveying mechanism 2 is large, the sludge can be completely accommodated and dried, so as to ensure a relatively high drying efficiency of the whole device; the feed inlet 31 and the tail gas discharge port 33 are provided on the top of the dome 341, which is convenient for connecting with the conveying mechanism 2 and for the relatively high-temperature tail gas to rise to the top and be discharged; the disk-type heat exchange and pushing assembly 35 is arranged in the heat exchange chamber 342 and contacts the sludge falling into the heat exchange chamber 342.

[0052] Further, an overflow port 343 is provided on the side surface of the outer shell 34, and a baffle is provided at the overflow port 343.

[0053] Specifically, the overflow port 343 is provided on the side surface of the heat exchange chamber 342, and the baffle is liftable to increase the minimum opening height of the overflow port 343 to control the overflow amount of the sludge; during sludge treatment, the discharge port 32 is in a closed state, so that the sludge conveyed to one end of the heat exchange chamber 342 near the overflow port 343 cannot be directly discharged through the discharge port 32, and the sludge accumulates below the overflow port 343. When the dried sludge accumulates to a certain amount, it can overflow through the overflow port 343, which can make the sludge fully dried, ensure that the water content of the sludge discharged from the overflow port 343 is relatively stable and the particles are uniform, and is convenient for subsequent treatment; when the sludge treatment process is completed, the discharge port 32 is opened to take out all the sludge accumulated below the overflow port 343, and the sludge drying operation is completed.

[0054] Preferably, a plurality of scrapers 36 are provided on the inner wall surface of the heat exchange chamber 342, and each scraper 36 extends into the gap between two adjacent heat exchange plates 351.

[0055] Specifically, the scraper 36 is provided on the inner wall of the heat exchange chamber 342, and the scraper 36 extends into the gap of the heat exchange plate 351. When the heat exchange plate 351 contacts the sludge with a relatively high water content, it will adhere to the heat exchange plate 351, which will prevent the heat exchange plate 351 from fully contacting the sludge, resulting in a poor heating effect and affecting the sludge drying effect. The distance between the scraper 36 and the heat exchange plate 351 is relatively small, and it can scrape off the sludge adhering to the heat exchange plate 351 when the heat exchange plate 351 rotates, making the sludge drying smoother and ensuring the sludge drying effect.

[0056] Preferably, a drain port (not shown in the figure) is also provided on the material bin 11, and the drain port is provided on the side surface of the material bin 11.

[0057] Specifically, the drain outlet is opened on the side of the silo 11. The drain outlet is usually in a closed state. When maintenance is required, the inside of the silo 11 is cleaned, and the sewage from the cleaning is discharged through the drain outlet. A screen can also be installed at the drain outlet to regularly discharge the leachate of the sludge in the bin body 111 through the drain outlet, reducing the water content of the sludge in the bin body 111.

[0058] The working process of the present utility model is as follows: The sludge to be treated is uniformly transported and placed in the silo 11. When the sludge storage reaches a certain amount, the sludge drying operation process is automatically or manually started; the valve at the open end is opened to connect the bin body 111 and the conveying mechanism 2, and at the same time, the arch-breaking sliding frame 12 in the bin body 111 is controlled to start, pushing the sludge in the bin body 111 to move downward and fall into the inside of the conveying bin 21;

[0059] The screw 221 and the second odor extraction port 211 are started synchronously. The blade group 222 rotates to push the sludge falling into the conveying bin 21 to move to the other end of the conveying bin 21. During the pushing process, the sludge is stirred. During the sludge propulsion and stirring process, the second odor extraction port 211 extracts the harmful gases generated by the sludge to the harmful gas treatment device, and the treated gas is discharged after meeting the emission requirements; the sludge is pushed by the screw 221 and the blade group 222 to move to the other end of the conveying bin 21, and the gate valve 23 is opened, and the sludge enters the inside of the heat exchange bin 342 through the feeding port and the feeding port 31 of the drying mechanism 3;

[0060] When the sludge enters the conveying bin 21, high-temperature steam can be introduced into the heat exchange disk 351 for preheating to ensure that the sludge can be directly dried after entering the drying mechanism 3. After the sludge enters the drying mechanism 3, the heat exchange disk 351 starts to rotate, stirring and heating the sludge in contact with it. The sludge slowly moves driven by the disk-type heat exchange and pushing assembly 35 to ensure that the sludge is fully heated and stirred. The sludge slowly moves to the other end of the heat exchange bin 342 and overflows from the discharge port 32 on the side of the heat exchange bin 342 to obtain the dried sludge, which can be collected and then uniformly subjected to subsequent treatment.

[0061] In summary, the embodiment of the present utility model provides a sludge drying treatment device, which is tightly connected between various structures, and two screws 221 and the blade group 222 thereon are provided to convey the sludge, effectively improving the conveying and treatment efficiency of the sludge; odor extraction ports or tail gas discharge ports 33 are provided in each structure to treat and discharge the harmful gases generated during the sludge storage and drying processes, avoiding environmental pollution by harmful gases; the heat exchange disk 351 is provided to effectively increase the heating area of the sludge and improve the drying effect; the scraper 36 is used to ensure the smooth operation of the heat exchange disk 351 without jamming and ensure the drying effect.

[0062] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present utility model.
