Description
Technical Field
[0001] This utility model relates to the field of sludge transfer technology, and in particular to a sludge transport vehicle with an automatic deodorization device. Background Technology
[0002] In urban wastewater treatment and industrial sludge disposal, dewatered sludge often exists in a semi-fluid state, requiring efficient and safe transportation methods to transfer it from the source to the treatment plant. With increasing environmental awareness and growing demand for sludge treatment, traditional transportation tools can no longer meet the professional requirements of modern sludge transportation, which has spurred the research and development and application of specialized sludge transport vehicles.
[0003] The sludge transport vehicle mainly consists of a chassis, a sealed compartment, a sludge loading device, an unloading device, and a control system. The chassis provides the power and load-bearing foundation. The sealed compartment adopts a fully enclosed design to prevent sludge leakage and odor emission. The sludge loading device can suck sludge into the compartment using a sludge pump or mechanical loading. The unloading device includes a hydraulic lifting system and a self-unloading door. The hydraulic system controls the tilting of the compartment and opens the self-unloading door to achieve rapid unloading of sludge. During operation, the sludge transport vehicle travels to the loading point and uses the loading device to complete the sludge loading. The compartment remains sealed during transportation. After arriving at the unloading point, the hydraulic system lifts the compartment, and the self-unloading door opens to dump the sludge into the designated location. The entire process is efficient, safe, and environmentally friendly.
[0004] With increasingly stringent environmental protection requirements, existing sludge transport vehicles often cause odor pollution from sludge during transportation due to the lack of efficient deodorization mechanisms, affecting residents' lives and the city's image, and even causing secondary pollution. Therefore, a sludge transport vehicle equipped with an automatic deodorization device is proposed to solve the above problems. Utility Model Content

[0015] The above technical solution allows the sliding ring to rotate more flexibly in the flow pipe, and the bottom of the carriage is rotatably connected to the base. With the help of the telescopic column, the tilt angle of the carriage can be easily changed, which facilitates the sludge unloading operation.
[0016] As a further description of the above technical solution:
[0017] The loading and unloading mechanism includes a rotating rod, the outside of which is rotatably connected to the top of the carriage, the top of which is rotatably connected to an inlet cover plate, the top of which is rotatably connected to a hydraulic rod one, the outside of which is rotatably connected to a hydraulic rod two, the drive end of which is fixedly connected to an unloading cover plate, and the top of which is rotatably connected to a hinge.
[0018] Through the above technical solution, the rotating rod, feed cover plate, hydraulic rod one, hydraulic rod two, discharge cover plate and hinge of the loading and unloading mechanism cooperate with each other to realize convenient loading and unloading of sludge, thereby improving the efficiency of sludge transportation.

[0021] The above technical solution ensures that the feed cover and discharge cover can be opened and closed stably, which facilitates the loading and unloading of sludge and ensures the airtightness of the compartment when not in use, preventing the emission of odors.
[0022] As a further description of the above technical solution:
[0023] The telescopic column is externally rotatably connected to the outside of the carriage, and the bottom end of the feed cover plate contacts the top end of the carriage.
[0024] The above technical solution involves a telescopic column that is rotatably connected to the outside of the carriage, allowing for flexible control of the carriage's tilt angle. The feed cover plate contacts the top of the carriage, ensuring a tight seal during sludge transport and preventing leakage.
[0025] As a further description of the above technical solution:
[0026] The pressure regulating mechanism includes a fixed cylinder, which is fixedly connected to the top of the carriage.

A limiting ring is fixedly connected to the bottom end of the inner cylinder, and a telescopic spring is fixedly connected to the inside of the inner cylinder. An air outlet is provided inside the fixed cylinder.
[0027] Through the above technical solution, the fixed cylinder, outer cylinder, inner cylinder, limiting ring, telescopic spring and air outlet of the pressure regulating mechanism work together to automatically vent when the pressure inside the compartment is too high, and prevent external impurities from entering the compartment after the pressure is normal, thus ensuring the stability and safety of the pressure inside the compartment during transportation.
[0028] As a further description of the above technical solution:
[0029] The outer part of the limiting ring is slidably connected to the inside of the fixed cylinder, and the top end of the telescopic spring is fixedly connected to the inside of the outer cylinder;
[0030] Through the above technical solution, the limiting ring slides smoothly inside the fixed cylinder, and the telescopic spring can accurately push the limiting ring back to its position, further ensuring the stable and reliable function of the pressure regulating mechanism in automatically venting air and preventing impurities from entering.
[0031] This utility model has the following beneficial effects:
[0032] 1. In this utility model, the hydraulic rod is activated to open the feed cover and load sludge. After transportation to the destination, the carriage is tilted and the unloading cover is opened using the telescopic column and hydraulic rod to complete the unloading. During the journey, the atomizer atomizes the deodorizer and delivers it through the transmission pipe, connecting pipe and flow pipe. The deodorizing gas is sprayed in a rotating manner by the rotating component, which can fully contact and neutralize the odor molecules, effectively improve the transportation environment and reduce the impact of odor emission on the surrounding environment.
[0033] 2. In this utility model, during transportation, the gas produced by microorganisms in the sludge causes pressure changes inside the compartment. When the pressure is too high, the gas impacts the limiting ring, causing it to slide and open the vent to release pressure. After the pressure is released, the telescopic spring pushes the limiting ring to reset and close the vent, preventing external impurities from entering. This ensures stable pressure inside the compartment and safe transportation, and extends the service life of the equipment. Attached Figure Description

Detailed Implementation
[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0042] Reference Figures 1 to 2 This utility model provides an embodiment of a sludge transport vehicle with an automatic deodorization device, including a cargo box 1. The cargo box 1 serves as the main structure for loading sludge, providing a relatively enclosed space for sludge transport and ensuring that the sludge does not spill during transport. The cargo box 1 is equipped with a loading and unloading mechanism 2, which can conveniently load and unload sludge, improving the efficiency of sludge transport. The bottom of the cargo box 1 is fixedly connected to a base 5, which provides stable support for the entire sludge transport vehicle and ensures the stability of the vehicle during operation. The top of the base 5 is equipped with a deodorization mechanism 3, which can effectively neutralize the odor generated by the sludge in the cargo box 1 and improve the transport environment. The top of the cargo box 1 is equipped with a pressure regulating mechanism 4, which can regulate the pressure inside the cargo box 1 to ensure stable pressure and ensure transport safety. The top of the base 5 is fixedly connected to a telescopic column 6, which can control the tilt angle of the cargo box 1 to facilitate the unloading operation of sludge.
[0043] Specifically, when sludge needs to be transported, the sludge is loaded into a relatively enclosed compartment 1 to prevent spillage during transportation. The loading and unloading mechanism 2 can efficiently complete the loading and unloading of sludge. During vehicle operation, the base 5 provides stable support to ensure smooth movement. The deodorization mechanism 3 neutralizes the odor inside the compartment 1. The pressure regulating mechanism 4 regulates the pressure inside the compartment 1 to ensure transportation safety. During unloading, the telescopic column 6 controls the tilt of the compartment 1 to facilitate sludge discharge.
[0044] The deodorizing mechanism 3 includes a storage box 31 for storing deodorizing agent. The storage box 31 is externally fixed to the top of the base 5, ensuring it does not shake during vehicle operation. An atomizer 32 is externally fixed to the storage box 31, atomizing the deodorizing agent into nano-sized particles, making it easier for the agent to contact odor molecules. A transmission pipe 33 is externally connected to the atomizer 32, delivering the atomized deodorizing agent into the vehicle compartment 1, ensuring the deodorizing agent reaches its intended function smoothly. The external of the transmission pipe 33 is fixedly connected to the inside of the carriage 1. This connection method ensures the airtightness of the transmission. The inside of the carriage 1 is fixedly connected to the connecting pipe 34. The external of the connecting pipe 34 is fixedly connected to multiple flow pipes 35. The connecting pipe 34 can evenly distribute the deodorant delivered by the transmission pipe 33 into each flow pipe 35. The flow pipes 35 further deliver the deodorant to each corner of the carriage 1. The inside of the flow pipe 35 is equipped with a rotating component 36. The rotating component 36 can make the deodorant rotate and spray, thereby improving the deodorizing effect.
[0045] Specifically, during deodorization, the deodorant stored in the storage box 31 is atomized into nano-sized particles by the atomizer 32, and then transported to the connecting pipe 34 in the carriage 1 through the transmission pipe 33. The connecting pipe 34 then distributes the particles to each flow pipe 35, and finally achieves rotating spraying through the rotating component 36, thereby improving the deodorization effect.
[0046] The loading and unloading mechanism 2 includes a rotating rod 22, which serves as a support shaft for the rotation of the feed cover 21. The rod is externally rotatably connected to the top of the carriage 1, ensuring flexible rotation. The feed cover 21 is rotatably connected to the top of the rotating rod 22. The feed cover 21 controls the loading of sludge and can close the carriage 1 when no sludge is being loaded, preventing odor emissions. A hydraulic rod 1 23 is rotatably connected to the top of the carriage 1, providing power for the rotation of the feed cover 21, enabling it to open and close smoothly. A hydraulic rod 26 is rotatably connected to the outside of the carriage 1, with a discharge cover 25 fixedly connected to the drive end of the hydraulic rod 26. The hydraulic rod 26 drives the rotation of the discharge cover 25, allowing it to open and close smoothly. To control the discharge of sludge, the top of the discharge cover 25 is rotatably connected to a hinge 24. The hinge 24 allows the discharge cover 25 to rotate in a specific manner to ensure smooth discharge. The bottom end of the hinge 24 is fixedly connected to the top of the carriage 1 to ensure the stability of the connection. The outside of the discharge cover 25 is in contact with the outside of the carriage 1, which ensures the sealing of the carriage 1 when closed. The drive end of the hydraulic rod 23 is fixedly connected to the outside of the rotating rod 22. This connection method enables the control of the feed cover 21. The outside of the telescopic column 6 is rotatably connected to the outside of the carriage 1 to facilitate the control of the tilt angle of the carriage 1 for discharge. The bottom end of the feed cover 21 is in contact with the top of the carriage 1 to ensure the sealing of the carriage 1.
[0047] Specifically, when loading sludge, hydraulic rod 23 is activated to drive the feed cover 21 to rotate around the rotating rod 22 and open, allowing the sludge to be loaded into the truck bed 1. When not loading, the feed cover 21 is closed to prevent odor from escaping. When unloading, telescopic column 6 is activated to tilt the truck bed 1, and at the same time, hydraulic rod 26 drives the unloading cover 25 to rotate around the hinge 24 and open, allowing the sludge to be unloaded smoothly. After unloading is completed, the unloading cover 25 is closed to ensure the airtightness of the truck bed 1.
[0048] Reference Figures 2 to 4 The rotating assembly 36 includes a rotating head 361, which can rotate inside the flow pipe 35. Its external rotation is connected to the inside of the flow pipe 35 to ensure smooth rotation. A fixed column 362 is fixedly connected inside the rotating head 361. Multiple drive blades 363 are fixedly connected to the external of the fixed column 362. The fixed column 362 provides a mounting base for the drive blades 363. The drive blades 363 drive the fixed column 362 and the rotating head 361 to rotate under the impact of the gas. Multiple spray nozzles 364 are opened on the external of the rotating head 361. The spray nozzles 364 are used to spray deodorizing gas into the interior of the carriage 1. A sliding ring 365 is fixedly connected to the external of the rotating head 361. The sliding ring 365 can reduce the friction between the rotating head 361 and the flow pipe 35, making its rotation more flexible. The external rotation of the sliding ring 365 is connected to the inside of the flow pipe 35. The bottom end of the carriage 1 is rotatably connected to the top of the base 5. This connection method allows the carriage 1 to tilt under the action of the telescopic column 6.
[0049] Specifically, when the deodorizing gas is transported in the flow pipe 35, it impacts the transmission blade 363, which drives the fixed column 362 and the rotating head 361 to rotate. The rotating head 361 rotates flexibly in the flow pipe 35 through the sliding ring 365, so that the deodorizing gas is sprayed out from the spray nozzle 364. The bottom of the carriage 1 is rotatably connected to the base 5, and the tilt angle of the carriage 1 can be changed in conjunction with the telescopic column 6.
[0050] Reference Figure 1 , Figure 2 and Figure 5The pressure regulating mechanism 4 includes a fixed cylinder 41, which provides installation space for other components of the pressure regulating mechanism 4. It is externally fixedly connected to the top of the carriage 1. An outer cylinder 42 is fixedly connected inside the fixed cylinder 41. The outer cylinder 42 provides a guide for the sliding of the inner cylinder 43. The inner cylinder 43 is slidably connected inside the outer cylinder 42. The inner cylinder 43 slides inside the fixed cylinder 41 when the pressure changes. A limiting ring 45 is fixedly connected to the bottom of the inner cylinder 43. The limiting ring 45 can control the opening and closing of the air outlet 46. A telescopic spring 44 is fixedly connected inside the inner cylinder 43. The telescopic spring 44 is used to push the limiting ring 45 back to its original position after the pressure is released. An air outlet 46 is opened inside the fixed cylinder 41. The air outlet 46 is used to discharge excess gas inside the carriage 1. The outer side of the limiting ring 45 is slidably connected to the inside of the fixed cylinder 41 to ensure the stability of the sliding. The top of the telescopic spring 44 is fixedly connected to the inside of the outer cylinder 42 to ensure that the telescopic spring 44 can function properly.
[0051] Specifically, when the pressure inside the carriage 1 is too high, the gas impacts the limiting ring 45, causing it to slide inside the fixed cylinder 41, opening the vent 46 to release excess gas. After the pressure is released, the telescopic spring 44 pushes the limiting ring 45 back to its original position, closing the vent 46 to prevent external impurities from entering the carriage 1.
[0052] Working principle: When the operator needs to transport sludge, hydraulic rod 23 is activated. Hydraulic rod 23 drives the feed cover 21 to rotate around the rotating rod 22, thereby opening the feed cover 21 and allowing the sludge to be injected into the truck body 1. The sludge is then transported by the vehicle. Upon reaching the designated location, the telescopic column 6 is activated, causing the truck body 1 to rotate. Hydraulic rod 26 then drives the discharge cover 25 to rotate via hinge 24, allowing the sludge inside the truck body 1 to be discharged normally. During vehicle operation, fog... The atomizer 32 atomizes the deodorizer inside the storage box 31 into nano-sized particles, and delivers them to the inside of the connecting pipe 34 through the transmission pipe 33, and then through the flow pipe 35. When the gas is transported inside the flow pipe 35, it impacts the drive blade 363, which causes the fixed column 362 to drive the rotating head 361 to rotate inside the flow pipe 35 through the sliding ring 365. This results in the deodorizing gas being discharged through the spray nozzle 364, achieving a rotating spraying effect and improving the effect of fully contacting and neutralizing odor molecules.
[0053] When the vehicle is loaded with sludge for transportation, the microorganisms in the sludge inside the compartment 1 will produce gas, which will cause changes in the pressure inside the compartment 1, requiring a depressurization operation. When the pressure inside the compartment 1 is too high, the limiting ring 45 will be impacted by the gas, causing it to slide inside the fixed cylinder 41. When the limiting ring 45 releases its restriction on the vent 46, the gas will be discharged through the vent 46. After the depressurization is completed, the telescopic spring 44 will push the limiting ring 45 to restrict the vent 46 again, thereby achieving the effect of automatic exhaust and preventing external impurities from entering the compartment 1.
[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
