Description

Technical Field

[0001] The utility model relates to the technical field of sludge treatment equipment, in particular to a belt-type filter press dehydration equipment for separating wastewater sludge. Background Art

[0002] Belt filter press dewatering equipment is a mechanical equipment commonly used in wastewater treatment and sludge dewatering. Among them, the more commonly used is the belt filter press, which is a high-efficiency solid-liquid separation equipment and is widely used in sewage treatment, sludge dewatering, industrial wastewater treatment and other fields. It squeezes out the water in the sludge through the movement of the filter belt and the action of a series of pressing rollers, thereby achieving sludge reduction and stabilization.

[0003] After searching, it was found that the patent with announcement number CN215667679U discloses a belt filter press for treating piling sludge. Although a collection box is set at the mud outlet to collect the dehydrated sludge, the length of the collection box needs to be consistent with the width of the equipment in order to completely collect the sludge, resulting in the collected sludge being relatively scattered and inconvenient for unified treatment.

[0004] In view of the above problems, the present utility model document proposes a belt filter press dewatering equipment for wastewater sludge separation. Utility Model Content

[0005] The utility model provides a belt filter press dewatering device for separating wastewater from sludge, which solves the problem in the prior art that although a collecting box is provided at the mud outlet to collect the dehydrated sludge, the length of the collecting box needs to be consistent with the width of the equipment in order to completely collect the sludge, resulting in the collected sludge being relatively scattered and inconvenient for unified treatment.

[0006] The utility model provides the following technical solutions:

[0007] A belt filter press dehydration device for wastewater sludge separation, comprising:

[0008] A base frame, wherein a belt filter press body is fixedly installed on the top of the base frame, a U-shaped baffle for guiding is rotatably installed on the mud outlet of the belt filter press body, and universal wheels are fixedly installed at the four corners of the bottom of the base frame;

[0009] The sludge collecting component is installed on the base frame and is used to collect the dehydrated sludge for unified treatment;

[0010] A buffer assembly is provided at the bottom of the U-shaped baffle to prevent the lower end of the U-shaped baffle from being rigidly connected to the base frame;

[0011] The leveling component is located at the bottom of the base frame and is used to level the equipment and improve the support stability of the universal wheel.

[0012] In a possible design, the sludge collecting assembly includes a collecting cylinder placed horizontally on a base frame via two mounting frames, and an open receiving port is provided on the top of the collecting cylinder for receiving sludge discharged from the U-shaped baffle.

[0013] In one possible design, the same rotating rod is rotatably mounted at both ends of the inner wall of the collecting tube, a spiral conveying blade is fixedly mounted on the outer wall of the rotating rod, a driving motor for driving the rotating rod to rotate is fixedly mounted on the outer wall of the collecting tube, and a mud discharge port is provided at the edge of the bottom of the collecting tube.

[0014] In one possible design, the buffer assembly includes three dampers equidistantly hinged to the bottom edge of the U-shaped baffle, a mounting plate corresponding to the position of the damper is fixedly provided on one side of the outer wall of the collecting tube, and the bottom end of the damper is hinged to the top of the corresponding mounting plate.

[0015] In a possible design, a matching buffer spring is sleeved on the damper.

[0016] In one possible design, the leveling assembly includes four screws fixedly arranged in a rectangular array at the bottom of the base frame, the screws are close to the corresponding universal wheels, and a cylindrical support block is threadedly connected to the screws, and the cylindrical support block is hollow.

[0017] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0018] The working principle and usage process of this technical solution are as follows:

[0019] During use, the vertical positions of the four columnar support blocks are adjusted according to the unevenness of the ground to ensure that the equipment is placed stably and to improve the support stability of the universal wheel. The wastewater sludge to be treated is fed into the belt filter press body and then subjected to filtration and dehydration treatment. During the dehydration process, the sludge is gradually dehydrated under the action of the belt filter press and is eventually discharged from the mud outlet. The discharged sludge is guided by the U-shaped baffle and falls into the open receiving port of the collecting barrel in the mud collection component. After the sludge enters the collecting barrel, the driving motor drives the rotating rod and the spiral conveying blades thereon to rotate. The rotation of the spiral conveying blades transports the sludge from one end of the collecting barrel to the other end, and finally discharged through the mud outlet for subsequent unified treatment.

[0020] During the sludge discharge process, three sets of dampers and buffer springs act as shock absorbers to avoid rigid impact, thereby preventing the U-shaped baffle from deforming or making excessive noise during long-term use. When the equipment needs to be moved to another work site, the universal wheels at the bottom of the base frame can be used to easily push the equipment. After arriving at the new site, the screws and columnar support blocks in the leveling assembly can be adjusted to ensure that the equipment is in a level state again, thereby improving working stability and safety.

[0021] The utility model has the following beneficial effects:

[0022] The design of the mud gathering component in the utility model enables the dehydrated sludge to be automatically gathered and discharged for subsequent unified treatment; the introduction of the buffer component effectively avoids the rigid impact between the U-shaped baffle and the base frame, extends the service life of the equipment, and reduces noise pollution; the design of the leveling component enables the equipment to maintain a horizontal state on different ground surfaces, improves the supporting stability of the universal wheel, and ensures the safety and reliability of the equipment during operation.
