Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, specifically a vehicle-mounted liftable sludge thickening device. Background Technology

[0002] With the rapid development of global urbanization, sludge treatment has become an increasingly prominent issue. Vehicle-mounted sludge thickening devices, as efficient and convenient sludge treatment equipment, play a vital role in urban environmental management. However, existing vehicle-mounted sludge thickening devices generally suffer from a key problem: their height is typically 5-6 meters. This makes it difficult for the equipment to pass smoothly during transportation, especially when crossing height restriction barriers, greatly limiting its application range. Particularly in emergency situations, such as sludge treatment in hospitals, existing vehicle-mounted sludge thickening devices often cannot arrive and be put into use in a timely manner due to transportation limitations. Therefore, to meet the needs of various emergency situations and different transportation environments, developing a height-adjustable vehicle-mounted sludge thickening device has become particularly important. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a vehicle-mounted, liftable sludge thickening device that can adapt to different transportation and usage environments, thereby expanding its application scope in emergency and special situations.

[0004] A vehicle-mounted, liftable sludge thickening device includes: an outer sleeve with an open top and supporting legs and a discharge port at the bottom; a top sleeve fitted over the outer sleeve, with a mixing zone inside the top of the top sleeve, two feed branch pipes connected to the mixing zone, and a main feed pipe connected to the two feed branch pipes, and a sealing structure at the connection between the top sleeve and the outer sleeve; and a height adjustment mechanism connecting the outer sleeve and the top sleeve for driving the top sleeve to move up and down within the outer sleeve.

[0005] Preferably, the height adjustment mechanism includes a top sleeve connecting plate, an outer sleeve connecting plate, and a lifting cylinder. The top sleeve connecting plate is connected to the upper-middle part of the outer side of the top sleeve, and the outer sleeve connecting plate is connected to the upper-middle part of the outer side of the outer sleeve. The lifting cylinder is fixed to the outer sleeve connecting plate, and its output end is connected to the top sleeve connecting plate. When the height of the top sleeve needs to be adjusted, the operator only needs to control the extension and retraction of the lifting cylinder to achieve the lifting and lowering movement of the top sleeve. Furthermore, because the lifting cylinder has a large thrust and stroke range, it can meet the needs of different height adjustments.

[0006] Preferably, the sealing structure is provided at both the upper and lower points of the connection between the top sleeve and the outer sleeve. The double-layer sealing structure significantly enhances the sealing performance of the device, effectively preventing material leakage during processing.

[0007] Preferably, the sealing structure includes a square tube and sealing rubber filled within the square tube. The square tube is arranged around the inner wall of the outer sleeve, with an opening on the side facing the top sleeve. The sealing rubber abuts against the top sleeve. It should be noted that the sealing rubber fits tightly against the top sleeve, effectively preventing material leakage during processing. Simultaneously, due to the support of the square tube, the sealing rubber can withstand high pressure, ensuring good sealing performance even under high-pressure environments. If the sealing rubber wears or is damaged, only the sealing rubber needs to be replaced, resulting in low maintenance costs and simple operation.

[0008] Preferably, the sealing structure includes a sealing rubber, and a limiting groove is recessed inward on the outer wall of the top sleeve. The sealing rubber is disposed within the limiting groove, and the side of the sealing rubber away from the top sleeve abuts against the outer sleeve. The sealing rubber is confined within the limiting groove, preventing displacement and ensuring tight contact with the outer sleeve for a reliable sealing effect. Simultaneously, the limiting groove design fixes the installation position of the sealing rubber, facilitating installation and maintenance by operators.

[0009] Preferably, the height adjustment mechanism comprises multiple sets. The design of multiple sets of height adjustment mechanisms enhances the stability of the top sleeve's lifting and lowering, ensuring a stable height under various handling conditions.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention provides a vehicle-mounted, liftable sludge thickening device, comprising an outer sleeve, a top sleeve, and a height adjustment mechanism. The height adjustment mechanism allows the device to adapt to various height restrictions during transportation. During transport, the top sleeve can be lowered into the outer sleeve to reduce the overall height and facilitate passage over obstacles such as height restriction bars. In use, the height adjustment mechanism can extend the top sleeve beyond the outer sleeve to increase processing capacity and improve efficiency. Furthermore, the sealing structure ensures excellent airtightness at the connection between the top sleeve and the outer sleeve, effectively preventing material leakage during wastewater treatment and improving processing efficiency and quality. Therefore, the flexibility and height adjustability of this vehicle-mounted, liftable sludge thickening device make it suitable not only for urban environmental management but also for various emergency and special applications, such as hospitals and industrial areas, greatly enhancing transportation convenience and broadening its applicability.

Detailed Implementation

[0016] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0017] See Figure 1 This embodiment provides a vehicle-mounted liftable sludge thickening device, which includes an outer sleeve 1, a top sleeve 2, and a height adjustment mechanism 3. The top of the outer sleeve 1 is open, and the bottom of the outer sleeve 1 is provided with a support leg 11 and a discharge port 12. The top sleeve 2 is fitted from the top of the outer sleeve 1 into the outer sleeve 1. A mixing zone 21 is provided inside the top of the top sleeve 2. Two feed branch pipes 22 are provided on the mixing zone, and a feed main pipe 23 is connected to the two feed branch pipes 22. A sealing structure 4 is provided at the connection between the top sleeve 2 and the outer sleeve 1. The height adjustment mechanism 3 connects the outer sleeve 1 and the top sleeve 2 to drive the top sleeve 2 to move up and down within the outer sleeve 1.

[0018] Preferably, the sealing structure 4 is provided at both the top and bottom of the connection between the top sleeve 2 and the outer sleeve 1. The provision of two layers of sealing structure 4 greatly enhances the sealing performance of the device and effectively prevents material leakage during processing.

[0019] Preferably, the sealing structure 4 includes a square tube and sealing rubber filled inside the square tube. The square tube is arranged around the inner wall of the outer sleeve 1, with an opening on the side facing the top sleeve 2. The sealing rubber abuts against the top sleeve 2. It should be noted that the sealing rubber fits tightly against the top sleeve 2, effectively preventing material leakage during processing. Simultaneously, due to the support of the square tube, the sealing rubber can withstand high pressure, ensuring good sealing performance even under high pressure. If the sealing rubber wears or is damaged, only the sealing rubber needs to be replaced, resulting in low maintenance costs and simple operation.

[0020] Alternatively, the sealing structure 4 may include a sealing rubber. A limiting groove is recessed inward on the outer wall of the top sleeve 2, and the sealing rubber is disposed within this groove. The side of the sealing rubber away from the top sleeve 2 abuts against the outer sleeve 1. The sealing rubber is confined within the limiting groove, preventing displacement and ensuring tight contact with the outer sleeve 1 for a reliable sealing effect. Furthermore, the limiting groove design fixes the installation position of the sealing rubber, facilitating installation and maintenance by operators.

[0021] Preferably, the height adjustment mechanism 3 comprises multiple sets. The design of multiple sets of height adjustment mechanisms 3 enhances the stability of the lifting and lowering of the top sleeve 2, ensuring that a stable height can be maintained under various processing conditions.

[0022] It should also be noted that the feed manifold 23 is used to input sludge water with a moisture content of 98% and PAM reagent.

[0023] This utility model provides a vehicle-mounted, liftable sludge thickening device, comprising an outer sleeve 1, a top sleeve 2, and a height adjustment mechanism 3. Through the height adjustment mechanism 3, the device can be adjusted in height to adapt to various height restrictions during transportation. During transport, the top sleeve 2 can be lowered to a certain extent into the outer sleeve 1 to reduce the overall height and facilitate passage over obstacles such as height restriction bars. In use, the height adjustment mechanism 3 can drive the top sleeve 2 to extend outside the outer sleeve 1, increasing the sludge processing capacity and improving work efficiency. Furthermore, the sealing structure 4 ensures good sealing at the connection between the top sleeve 2 and the outer sleeve 1, effectively preventing material leakage during wastewater treatment and improving treatment efficiency and quality. Therefore, the flexibility and height adjustability of this vehicle-mounted, liftable sludge thickening device make it suitable not only for urban environmental management but also for various emergency and special occasions, such as hospitals and industrial areas, greatly improving transportation convenience and broadening its application scope. Example

[0024] See Figure 2This embodiment 2 is largely the same as embodiment 1, except that the height adjustment mechanism includes a top sleeve connecting plate 301, an outer sleeve connecting plate 302, and a lifting cylinder 303. The top sleeve connecting plate 301 is connected to the upper middle part of the outer side of the top sleeve, and the outer sleeve connecting plate 302 is also connected to the upper middle part of the outer side of the outer sleeve. The lifting cylinder 303 is fixed to the outer sleeve connecting plate 302, and its output end is connected to the top sleeve connecting plate 301. When the height of the top sleeve needs to be adjusted, the operator only needs to control the extension and retraction of the lifting cylinder 303 to achieve the lifting and lowering movement of the top sleeve. Furthermore, because the lifting cylinder 303 has a large thrust and stroke range, it can meet the needs of different height adjustments.

[0025] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
