A continuous feeding device for papermaking waste residue belongs to the technical field of feeding devices for papermaking waste residue and comprises a feeding barrel, a feeding cylinder, a pressing bin and a feeding bin. The feeding cylinder is movably sleeved in the feeding barrel, the pressing bin is disposed above the feeding barrel and communicated with the feeding barrel, the feeding barrel is perpendicularly connected with the pressing bin, an arc-shaped smooth transitional structure is disposed at a joint of the feeding barrel and the pressing bin, a turning plate used for pressing materials is fittingly disposed in the pressing bin, the feeding cylinder is fixedly connected with a piston, the piston is fixedly connected with a piston rod, and a cooling jacket is fittingly arranged on the outside of the feeding barrel. The cooling jacket is added to the outside of the feeding barrel, the temperature of the materials is reduced, and a sealing function is realized. In addition, a rod sleeve, the piston rod, the piston and the feeding cylinder form a pushing device, and feeding continuity and stability of a system are guaranteed. Furthermore, the smooth transitional structure is arranged at the joint, and accordingly the continuous feeding device for papermaking waste residue can continuously, stably and safely feed the papermaking waste residue required by cracking of a high-temperature sealing cracking kettle.

The invention discloses a novel waterproof lamp and a method for manufacturing the same. The novel waterproof lamp comprises a lamp cap and a lamp shade which is formed by compression, wherein transparent glass which peripherally has a sealing ring is arranged at the front end of the lamp shade; and the transparent glass is fixed by the front end of the lamp shade in an edge-pressing mode. The novel waterproof lamp is characterized in that: the rear end of the lamp shade is in a sleeve shape; a lamp cap fixing seat is sleeved at the periphery of the sleeve; a flange which is bent outwards is arranged at the rear end part of the sleeve and used for fastening the lamp cap fixing seat and preventing the lamp cap fixing seat from being dropped; a movable fastener is arranged between the lamp cap fixing seat and the lamp cap; and a sealing piece is arranged between the front end of the lamp cap and a bending part at the rear end of the sleeve. The lamp does not have any screw connecting piece, and all parts are in fastening fit with one another, so the lamp is relatively higher in waterproof capacity, simple in structure and low in cost and has quite wide practical significance and market value.

The invention provides a bearing box of a slime pump. By the adoption of the bearing box of the slime pump, the problem that a sealing device of a bearing box of an existing 3PN slime pump is poor in sealing effect is solved. The bearing box of the slime pump comprises a cylindrical left shell and a cylindrical right shell. A first sealing structure which makes the right shell be connected with a main shaft in a sealed mode is arranged in the right shell. An annular groove is formed in the end face, close to the left shell, of the right shell. The inner end of the left shell is cylindrical and is connected into the annular groove in an inserted mode. A second sealing structure which makes the left shell and the right shell be connected in a sealed mode is arranged between the left shell and the right shell. The outer end of the left shell stretches out of the annular groove, and an annular shoulder is arranged on the outer side wall of the outer end of the left shell. The annular shoulder is fixedly connected with the right shell through a plurality of screws. A bearing is fixed in the left shell. The bearing, the left shell and the right shell share the same center line. The bearing box of the slime pump has the advantages of being good in sealing effect and stable in work.

The invention discloses an efficient extrusion type automatic sealing gate valve. The efficient extrusion type automatic sealing gate valve comprises a gate valve body, a valve rod and a positioning block, the valve rod is arranged on the inner side of the gate valve body, the inner wall of a side window is attached to the edge side of a filter cartridge, moreover, the filter cartridge is arrangedat the bottom of the inner side of the gate valve body, a bottom plate is fixed at the bottom end of a valve plate, moreover, the bottom end of the bottom plate is attached to the upper end surface of a contact plate, moreover, the contact plate is fixed in the gate valve body, the positioning block is fixed on the upper end surface of the contact plate, and the inner side of the positioning block is attached to the edge side of the bottom plate. According to the efficient extrusion type automatic sealing gate valve, a novel structural design is adopted so that the efficient extrusion type automatic sealing gate valve can perform extrusion self-locking after the valve rod rotates to control the gate plate for closing, the phenomenon that due to the fact that the valve rod and the gate plate are loosened, the sealing performance is affected is avoided, moreover, a extrusion positioning structure is designed, so that the stability of the gate plate during closing is further ensured, meanwhile, a detachable filtering structure is designed, and the filter structure can also cooperate with the gate plate for positioning and sealing, so that the overall sealing performance of the efficient extrusion type automatic sealing gate valve is ensured.
