Abstract
The utility model discloses a final-stage flexible extrusion device of a strip-type dehydrator, which comprises a final-stage main compression roller arranged on a stander and filter strips. The final-stage flexible extrusion device is characterized by also comprising a pair compression roller positioned under the main compression roller; the filter strips are positioned between the main compression roller and the pair compression roller; two ends of the pair compression roller are arranged on seat boards of two sides by a bearing and a bearing seat; one end of each seat board adjacent to the main compression roller is hinged with the stander; the other end of each seat board is connected with the lower part of a screw rod; each screw rod upwards runs through a supporting plate fixed on a bracket and a compression spring positioned on the supporting plate in turn; and a screw cap is arranged on the screw rod of the upper part of the compression spring. The final-stage flexible extrusion device can apply large extrusion force to dreg in the filter strips, thereby improving the dehydrating effect.
Description
Technical field
The utility model relates to a kind of final stage pressurizing unit of belt dewaterer.
Background technology
The belt dewaterer is a kind of dehydration machine that is widely used in various poor slags, its dewatering type has gravity dehydration, cramping dehydration and three kinds of forms of S type extrusion dehydration, S type extrusion dehydration role maximum wherein, S type extrusion dehydration district comprises rack-mounted several main pressure roller, is arranged alternately in the strainer of each main pressure roller upper and lower end, when being driven, strainer contacts with main pressure roller, poor slag in the strainer is squeezed and dewaters, so the suffered tension force of strainer is big more, and its dehydrating effect is good more; But strainer is subjected to the restriction of its intensity, and the tension force that bears is limited, and the poor slag power of being squeezed in the strainer can't unrestrictedly strengthen, and causes dehydrating effect bad.
The utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, and a kind of flexible pressurizing unit of final stage of belt dewaterer is provided, and it can apply bigger extruding force to poor slag in the strainer, thereby improves dehydrating effect.
The purpose of this utility model is achieved in that
The flexible pressurizing unit of a kind of final stage of belt dewaterer, comprise rack-mounted final stage master's pressure roller, strainer, it is characterized in that also comprising be positioned at main pressure roller side-lower to pressure roller, strainer is at them between the two, two ends to pressure roller are installed on the seat board of both sides by bearing and bearing block, the end that every seat board is adjacent with main pressure roller is articulated in frame, the other end links to each other with the bottom of a screw rod, every screw rod upwards passes the support plate that is fixed in support successively, places the compression spring on the support plate, is provided with nut on the screw rod above the compression spring;
By rotating screw cap the compression spring is applied pretightning force, the compression spring will push away on the screw rod, and seat board drives pressure roller is rotated around hinge, makes pressure roller is compressed strainer at any time, poor slag in the strainer is applied bigger extruding force, thereby improve dehydrating effect;
Further improve as the utility model, on the screw rod between nut and the spring, also be provided with spring bearer plate, can make spring keep firm;
In sum, the utility model can apply bigger extruding force to poor slag in the strainer, thereby improves dehydrating effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As depicted in figs. 1 and 2, the flexible pressurizing unit of the final stage of this belt dewaterer, comprise the final stage master's pressure roller 2 that is installed on the frame 1, strainer 3, be positioned at main pressure roller 2 side-lowers to pressure roller 4, strainer 3 is at them between the two, two ends to pressure roller 4 are installed on the seat board 5 of both sides by bearing and bearing block 6, every seat board 5 and main pressure roller 2 adjacent ends are articulated on the frame 1 by hinge 7, the other end links to each other with the bottom of a screw rod 8, every screw rod 8 upwards passes the support plate 9 that is fixed in support 1 successively, place the compression spring 10 on the support plate 9, spring bearer plate 11 is provided with nut 12 in screw rod 8 upper ends;
By rotating screw cap the compression spring is applied pretightning force, the compression spring will push away on the screw rod, and seat board drives pressure roller is rotated around hinge, makes pressure roller is compressed strainer at any time, poor slag in the strainer is applied bigger extruding force, thereby improve dehydrating effect; Because what pressure roller was applied strainer is compression, not fragile strainer, the big I of extruding force is regulated by nut.
Claims (2)
1, the flexible pressurizing unit of a kind of final stage of belt dewaterer, comprise rack-mounted final stage master's pressure roller, strainer, it is characterized in that also comprising be positioned at main pressure roller side-lower to pressure roller, strainer is at them between the two, two ends to pressure roller are installed on the seat board of both sides by bearing block and bearing, the end that every seat board is adjacent with main pressure roller is articulated in frame, the other end links to each other with the bottom of a screw rod, every screw rod upwards passes the support plate that is fixed in support successively, places the compression spring on the support plate, is provided with nut on the screw rod above the compression spring.
2, according to the flexible pressurizing unit of the final stage of claims 1 described belt dewaterer, it is characterized in that on the screw rod between nut and the spring, also being provided with spring bearer plate.
