Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration, in particular to a movable material distribution mechanism for high-pressure dehydration. Background Art

[0002] Numerous domestic sewage treatment plants generate large quantities of sludge daily. Currently, the primary dewatering equipment used includes belt (concentrating) filter presses, centrifuges, and chamber filter presses. Traditional dewatering typically results in sludge with a moisture content of around 80%. This level of sludge must undergo subsequent treatment to meet environmental protection requirements. Prior to dewatering, the sludge must be evenly distributed.

[0003] After searching, the publication number CN205007711U was found, which discloses a new type of uniform distribution device for sludge dewatering belt filter press, which includes a material limiting mechanism, a silo, a material sorting mechanism, and a distribution mechanism. A certain distance is set between the material limiting mechanism and the filter belt. The rotational movement of the material limiting mechanism is relative to the horizontal movement of the filter belt. The material sorting mechanism reciprocates and evenly distributes the sludge falling into the silo through the material sorting rake teeth. The distribution mechanism is composed of two distribution rollers with thorns that rotate relative to each other.

[0004] In the process of realizing the present utility model, the inventors found that there are at least the following problems in the prior art that have not been solved. In the above case, the reciprocating motion provided by the rocker motor and the rocker connecting rod device is used to evenly distribute the sludge falling in the middle of the silo to the entire range of the silo through the material sorting rake teeth. However, during use, it takes a lot of time to evenly distribute the sludge in the silo, which affects work efficiency.

[0005] Therefore, we propose a movable cloth mechanism for high-pressure dehydration, which can solve the above problems. Utility Model Content

[0011] As an optional solution of the technical solution of the present application, the distribution troughs are evenly distributed at the bottom end of the distribution funnel, and the distribution troughs are connected to the distribution funnel.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the servo motor is controlled to work, and the threaded rod can drive the distribution funnel connected to the slider to move back and forth above the silo to prevent sludge from accumulating on one side of the silo. The gear on the outside of the slider is engaged with the rack.

[0017] See also Figure 1-Figure 2 The utility model provides a technical solution: a movable material distribution mechanism for high-pressure dehydration, comprising a silo 1, a material distribution funnel 11 is arranged above the silo 1, and material distribution grooves 12 are evenly opened at the bottom end of the material distribution funnel 11; a first adjusting mechanism: used to adjust the material distribution position of the material distribution funnel 11, the first adjusting mechanism comprises two groups of sliders 14, the two groups of sliders 14 are symmetrically installed on both sides of the material distribution funnel 11, a threaded groove 15 is horizontally penetrated at the lower end of the front side of the slider 14, a threaded rod 16 is threadedly connected to the inner side of the threaded groove 15, brackets 17 are horizontally symmetrically installed above both sides of the silo 1, a servo motor 18 is fixedly connected to the outer side of the bracket 17, the threaded rod 16 is rotatably connected to the inner wall of the bracket 17 on both sides through a bearing, and the shaft end of the servo motor 18 is fixedly connected to one end of the threaded rod 16.

[0018] In this technical solution, the sludge to be dehydrated is introduced into the distribution funnel 11 and discharged into the silo 1 through the distribution grooves 12 evenly opened at the bottom of the distribution funnel 11. The servo motor 18 is controlled by the corresponding controller to drive the threaded rod 16 to rotate. The threaded rod 16 is threadedly connected to the threaded groove 15 at the lower end of the slider 14. During the rotation of the threaded rod 16, the two sets of sliders 14 can drive the distribution funnel 11 to move back and forth above the silo 1 to perform distribution operations, thereby preventing sludge from accumulating on one side of the silo 1.

[0019] In this embodiment, the second adjustment mechanism is used to adjust the discharge amount of the material distribution funnel 11. The second adjustment mechanism includes a connecting rod 2 and a rack 22. The connecting rod 2 is rotatably connected to the inner walls on both sides of the material distribution trough 12 through bearings. An adjustment blade 13 is installed on the outside of the connecting rod 2. The adjustment blade 13 is placed in the material distribution trough 12. The adjustment blade 13 is evenly distributed on the outside of the connecting rod 2, and the adjustment blade 13 matches the size of the material distribution trough 12. Gears 21 are fixedly installed at both ends of the connecting rod 2, and the rack 22 is horizontally fixedly installed on the inner wall of the bottom end of the bracket 17. The gear 21 is meshed with the rack 22.

[0020] In this technical solution, when the threaded rod 16 drives the slider 14 to move, it can drive the gear 21 at one end of the connecting rod 2 outside the slider 14 to move, and the gear 21 engages with the rack 22 on the bottom side of the bracket 17. During the movement of the slider 14, the rack 22 can drive the gear 21 to rotate, thereby driving the connecting rod 2 to rotate, and further driving the adjusting blade 13 to rotate in the feeding trough 12, which can automatically control the discharge amount of sludge, and further can evenly discharge the sludge in the feeding funnel 11 into the silo 1.

[0022] In this technical solution, the rack 22 is matched with the size of the silo 1. When the threaded rod 16 drives the distribution funnel 11 to move to the front and rear ends of the silo 1, the rack 22 can no longer drive the gear 21 to rotate, and the regulating blade 13 on the outside of the connecting rod 2 stops rotating, automatically stopping the discharge operation of the sludge inside the distribution funnel 11.

[0023] When a movable material distributing mechanism for high-pressure dehydration is used, the sludge to be dehydrated is introduced into the material distributing funnel 11, and is discharged into the silo 1 through the material distributing grooves 12 evenly opened at the bottom of the material distributing funnel 11. The servo motor 18 is controlled by the corresponding controller to work, which can drive the threaded rod 16 to rotate. The threaded rod 16 is threadedly connected to the threaded groove 15 at the lower end of the slider 14. During the rotation of the threaded rod 16, the two sets of sliders 14 can drive the material distributing funnel 11 to move back and forth above the silo 1 to perform material distributing operations, avoiding To prevent sludge from accumulating on one side of the silo 1, when the threaded rod 16 drives the slider 14 to move, it can drive the gear 21 at one end of the connecting rod 2 outside the slider 14 to move, and the gear 21 engages with the rack 22 on the bottom side of the bracket 17. During the movement of the slider 14, the rack 22 can drive the gear 21 to rotate, thereby driving the connecting rod 2 to rotate, and further driving the adjusting blade 13 to rotate in the feeding trough 12, which can automatically control the discharge amount of sludge and further discharge the sludge in the feeding funnel 11 evenly into the silo 1.
