Problems solved by technology

[0004] (1) Due to the high pressure and the large size of the filter press track, the operation of the filter press track is very cumbersome. When the traditional track drive mechanism is used, the track drive mechanism also needs to have the same specifications, so its structure is complex and the equipment is bulky. Heavy weight, resulting in very high energy consumption of the power source during operation, and poor stability of filter press crawler operation
[0005] (2) Due to the high pressure on the filter press track, it is easy to generate a large friction force, resulting in high energy consumption of the power source, easy to wear, and short service life of the filter press track.
[0006] (3) According to the demand of production volume, the demand of water content after sludge dehydration, etc., it is often necessary to adjust the angle between the upper and lower filter press tracks before locking and fixing the upper and lower filter press tracks. In this type of dehydration device, the traditional bolt-type fixing method is generally used for fixing the upper and lower filter press tracks. When the angle between the upper and lower filter press tracks changes, the bolt and the filter press track There will be an included angle, causing the surface contact between the bolt and the filter track to gradually become point contact, and the locking and fixing effect is not ideal
In addition, because the structure of the filter press track is often very heavy, the operation of its angle adjustment is quite difficult, especially in large-scale dewatering equipment, resulting in the failure to improve production efficiency

Embodiment 1

[0051] A kind of continuous pressurized belt dehydrator of present embodiment, as figure 1 or figure 2 As shown, it includes upper filter screen 1, lower filter screen 2, upper filter press track 3, lower filter press track 4, upper track support 5 and lower track support 6, the upper filter press track is installed on the upper track support, and the lower filter press track The track is installed on the lower track bracket, the upper filter is tensioned on the outer periphery of the upper filter press track, and the lower filter is tensioned on the outer periphery of the lower filter press track. Along the sludge conveying direction, a height is formed between the upper filter and the lower filter. Tapered wedge filter press zone. In this continuous pressurized dehydrator, the upper and lower filter press crawlers are respectively equipped with crawler belt transmission mechanisms 7 with the same structure. Rolling auxiliary transmission mechanisms 8 are respectively prov...

Embodiment 2

[0084] This embodiment is a continuous pressurized belt dehydrator. Compared with Embodiment 1, the difference is that in the crawler belt transmission mechanism, the support part is in the shape of a roller as a whole, and the two ends or / and the inner side of the support part are connected to the The mounting sleeves are connected by bearings. The support part of this structure has a better load-bearing effect and can better ensure the stability of equipment operation, but its weight will be larger than that of the cage structure of the same specification, which will increase the equipment cost.

Embodiment 3

[0086] This embodiment is a continuous pressurized belt dehydrator. Compared with Embodiment 1, the difference is that in the rolling auxiliary transmission mechanism, the partition in the installation frame is a combined structure, including the partition body and The upper fixing strip, and the through slots with upper openings are distributed on the bulkhead body (for the structure, please refer to Figure 6 ), each through-slot is correspondingly connected with a connecting shaft, and the same connecting shaft passes through the through-slot at the corresponding position on each bulkhead body; an upper fixing bar is provided on the top of the bulkhead body, and the upper fixing bar covers the opening of each through-slot above. When installing the partitions of this structure, first connect the rolling parts in series on the connecting shaft, then put them into the corresponding through grooves on the main body of each partition, and then cover the openings of the through ...

Abstract

The invention discloses a continuous pressurizing belt type dehydrator and a dehydration method. According to the continuous pressurizing belt type dehydrator, filter pressing tracks in the dehydratorare respectively provided with a track transmission mechanism; the track transmission mechanism comprises a rotating shaft, a supporting part and chain wheels; the supporting part is arranged on theperiphery of the rotating shaft; the multiple chain wheels are distributed on the rotating shaft; the outer diameter of each chain wheel is larger than the outer diameter of the supporting part; the tooth parts of each chain wheel are cooperatively connected to the filter pressing track; the outer surface of the supporting part is connected to the surface of the filter pressing track; and rollingtype auxiliary transmission mechanisms are respectively arranged on the upper side and the lower side of the wedge-shaped filter pressing area and the inner side of the filter pressing track. The dehydration method comprises: driving the filter pressing tracks to operate by using the rotating shaft and the chain wheels, supporting the filter pressing track by using the supporting part, and furtherdriving the filter pressing tracks to operate stably by using the relative movement between the rolling type auxiliary transmission mechanisms and the filter pressing tracks. According to the invention, the overall weight of the dehydrator is effectively reduced so as to substantially reduce the power source energy consumption of the filter pressing track and effectively improve the operation smoothness and stability of the filter pressing track.

Description

technical field [0001] The invention relates to the technical field of sludge dewatering, in particular to a continuous pressurized belt dehydrator and a dehydration method. Background technique [0002] In people's daily life and production, a large amount of sludge is produced every year. The recycling method of these sludge can be used as fertilizer for farmland, forest, grassland or desert improvement, etc., as well as for building materials and energy utilization. Since sludge generally contains a large amount of water, the water content is as high as 80%, so in the process of sludge resource treatment, sludge dehydration is a very important link and a common technology. [0003] At present, the commonly used sludge dewatering equipment mainly includes plate and frame sludge dewatering machine, box sludge dewatering machine, belt sludge dewatering machine, centrifugal sludge dewatering machine and so on. Among them, the belt filter press has the advantages of continuou...
