Therefore, even evaporate workshop section in pulping workshop, need adopt the feed back screw machine to carry out wet process material preparation, for example the current chinese patent that grants the bulletin number CN2622235Y discloses a feed back screw machine, including the cavity cylindricality casing that the level set up, set up the screw axis in the casing, set up the motor that is used for driving the screw axis in the casing outside, set up at the feed inlet at casing one end top and set up discharge gate and the feed back mouth in casing other end bottom be provided with the screen plate in the corresponding department of feed inlet in casing bottom, its advantage is: the wet process material preparation device has the advantages that the structure is simple and reasonable, the defect of the material return screw machine in the wet process material preparation process can be effectively overcome, and the usability and the yield of the material return screw machine are ensured.

However, in practical applications, the device has the following problems: the device has limited capability of removing heavy impurities, and when the heavy impurities such as silt, stones, glass, ironware and the like in the raw materials are increased, the impurity removing effect is not obvious, and the heavy impurities which are not removed easily cause serious abrasion of subsequent equipment and are scrapped in advance after entering a production system.

Disclosure of Invention

Aiming at the defects, the utility model provides a sand settling hopper structure for papermaking, which can effectively remove heavy impurities such as sediment, stones, glass, ironware and the like in raw materials, has good impurity removal effect, and avoids the situation that the heavy impurities enter a production system to cause serious abrasion of subsequent equipment and are scrapped in advance.

In order to achieve the above purpose, the present utility model adopts the following technical scheme:

the utility model provides a sand settling hopper structure for papermaking, includes feed back screw machine, its characterized in that: the shell, be close to the casing middle part sets up the funnel body, the both ends of shell are feed inlet and discharging pipe respectively, the big mouth end of funnel body up with the inboard intercommunication of casing bottom, the tip of funnel body is provided with the collecting vessel down.

Further, the collecting barrel comprises a collecting pipe which is vertically arranged, a first slag discharging valve and a second slag discharging valve are respectively arranged at the top end and the bottom end of the collecting pipe, and the first slag discharging valve is connected with the small opening end of the funnel body and the top end of the collecting pipe.

Further, one side of the funnel body is provided with an observation tube, the observation tube is close to the small opening end of the funnel body, and one end of the observation tube, which is far away from the funnel body, is provided with a transparent glass window.

Further, an opening is formed in the top of the shell.

The beneficial effects of the utility model are as follows:

in practical application, the discharging pipe is connected with the feeding end of the feed back screw machine, when the feed back screw machine is used, raw materials and heavy impurities enter the shell together through the feeding port, under the action of gravity sedimentation, the heavy impurities are precipitated in the large-mouth end of the funnel body in the middle of the shell and slide into the collecting barrel, and the precipitated raw materials are discharged into the feeding end of the feed back screw machine through the discharging pipe; the utility model can effectively remove the heavy impurities such as sediment, stones, glass, ironware and the like in the raw materials, has good impurity removing effect, and avoids the situation that the subsequent equipment is seriously worn and scrapped in advance due to the heavy impurities entering the production system.
