Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and thus the present invention is not limited to the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1, fig. 2, this embodiment aims at improving filtration efficiency, for this reason, the papermaking and pulping sewage treatment device that this embodiment provided, including being the device body 1 that the cuboid form set up, device body 1 wholly is the box-like setting of cuboid, and the setting is empty, is provided with sewage inlet 11 at the top of device body 1, and sewage inlet 11 sets up the central point at device body 1, can ensure like this that sewage gets into most the centre of concentrating behind the device body 1 in the middle of 1, can reduce the condition that both sides leaked, is provided with sewage outlet 12 in one side of device body 1, and sewage outlet 12 is close to the bottom setting of device body 1.

Be provided with filter 2 in device body 1, consider the corrosion scheduling problem, in this embodiment, filter 2 is resin board or other plastic slabs, in the device body 1 that 2 levels of filter set up, evenly distributed has filtration pore 21 on filter 2, in this embodiment, filtration pore 21 does not play filterable effect but plays the effect of leaking downwards, be provided with filter fiber cloth at 2 upper surfaces of filter, filter fiber cloth plays filterable effect, and filter 2's effect is mainly to playing the effect of supporting filter fiber cloth, and like this, the sewage after filtering from filter fiber cloth can be followed and filtered pore 21 interior downward flow.

In order to make the flat tiling that filter fiber cloth can be flat on filter 2, be provided with clamp plate 3 in the both sides of filter 2, bolted connection between clamp plate 3 and the filter 2, like this, utilize clamp plate 3 to push down filter fiber cloth, make its laminating filter 2 setting. Another purpose of the press plate 3 is to form a barrier to prevent the sewage from flowing out from both sides.

Be provided with lift cylinder 4 at the top of device body 1, the power end of lift cylinder 4 stretches into in the device body 1 and is connected with clamp plate 3, the main purpose of lift cylinder 4 is exactly that control filter 2 goes up and down, and the main reason that filter 2 goes up and down is provided with out thick liquid mouth 13 in one side of device body 1, filter 2 need go up and down to the below of out thick liquid mouth 13, just can ensure that sewage can not follow out thick liquid mouth 13 and flow, and the main purpose of play thick liquid mouth 13 is exactly that the sewage in a thick liquid pond has been discharged the back, discharge its paper pulp after filtering from out thick liquid mouth 13.

For this purpose, a scraper 5 for scraping pulp fibers of the filter fiber cloth toward the outlet 13 is provided in the apparatus body 1, and the scraper 5 reciprocates in the apparatus body 1. In this embodiment, a driving motor 6 is disposed outside the device body 1, a power end of the driving motor 6 is connected with a screw rod 61, the other end of the screw rod 61 is disposed at the pulp outlet 13, and thus, the scraper 5 is sleeved on the screw rod through a nut of the screw rod 61, and thus, under the action of the screw rod 61, the reciprocating motion of the scraper 5 is realized, so that the pulp is pushed to the pulp outlet 13, and due to the support of the filter plate 2, the scraping effect of the scraper 5 can be ensured, so that the reduced cleaning of the filter fiber cloth is realized.

In order to reduce the outflow of sewage from the periphery of the filter plate 2 as much as possible, in the present embodiment, the filter plate 2 is attached to the inner wall of the apparatus body 1. Specifically speaking, the cambered surface treatment is carried out at four corners of the inner wall of the device body 1, and the four corners of the filter plate 2 are arranged in an arc-shaped groove, so that the filter plate is attached to the device body and is not abraded greatly, and the problem of reducing corner flowing water is solved.

To further prevent the water from flowing around, the pressure plate 3 is disposed obliquely downward on a side away from the inner wall of the apparatus body 1. Thus, the sewage is made to flow toward the middle as much as possible, thereby ensuring the recovery rate.

In order to better receive the filtered pulp, the pulp outlet 13 is arranged above the sewage outlet 12, and the pulp outlet 13 and the sewage outlet 12 are arranged on two sides of the device body 1 differently. Therefore, the paper pulp cylinder can be arranged below the pulp outlet 13, and paper pulp can be collected conveniently.
