Abstract

The utility model belongs to the field of cement production equipment and discloses a discharging chute of a roller-entering press. The discharging chute comprises a hopper, a discharging pipe and a fin, the fin is welded on the inner wall of the discharging pipe and made by multiple small rectangular steel plates, and length of the fin is smaller than or equal to that of each of two sides of a rectangle of an inner cross section of the discharging pipe. By the discharging chute, damage to the discharging pipe due to discharging wear can be prevented, downtime is reduced, and running cost is saved.

Description

A kind ofly enter roll squeezer blanking scraper-trough conveyer

Technical field

The utility model belongs to cement manufacture plant field, particularly a kind ofly enters roll squeezer blanking scraper-trough conveyer.

Background technology

In cement production process, produce cement material used, need to carry out roll-in through roll squeezer, the equipment of supplying raw materials for roll squeezer enters roll squeezer through entering roll squeezer blanking scraper-trough conveyer, enter at present roll squeezer blanking scraper-trough conveyer, it is the tubular pipe that its cross section of being made by Plate Welding is rectangle, above it, one end connects hopper, one end connects feeding of roll squeezer mouth below, raw material slides to feeding of roll squeezer mouth one end from hopper along scraper-trough conveyer, due to distance, drop is large, blanking velocity is fast, the raw material falling can rub mutually with scraper-trough conveyer tube wall, can cause the Fast Wearing of blanking scraper-trough conveyer tube wall like this, to such an extent as to damage, cause frequent maintenance or replacing, increment rate fault power time, increased operating cost.

Summary of the invention

For the existing existing defect that enters roll squeezer blanking scraper-trough conveyer, the utility model proposes a kind of roll squeezer blanking scraper-trough conveyer that enters, comprise hopper, tremie pipe, is characterized in that: also comprise fin; Described hopper is arranged on the upper end of tremie pipe, and its lower port is connected with tremie pipe and seals; Described tremie pipe is arranged on hopper lower end, and the upper end of tremie pipe is connected and seals with the end opening of hopper, and the lower end of tremie pipe is connected with feeding of roll squeezer mouth, and the cross section of described tremie pipe is rectangle, by Plate Welding, is formed; Described fin is welded on the inwall of tremie pipe, by a plurality of little rectangular steel plates, is made, and the length of fin is less than or equal to respectively the length on two limits of rectangle of the interior cross section of tremie pipe, and the width of fin is 20-50 millimeter, and the thickness of fin is 3-5 millimeter; The installation direction of fin is that fin is inclined upwardly, and on fin, the angle of plane and tremie pipe sidewall plane is 60-75 degree, and a plurality of fins are for being arranged in parallel, and spacing is 150-250 millimeter.

Beneficial effect

The beneficial effects of the utility model are, can prevent from, because lower grinding abrasion is that tremie pipe damages, having reduced downtime, have saved operating cost.

Accompanying drawing explanation

Fig. 1 structural representation of the present utility model

1. hopper, 2. elephant trunk, 3. fin.

The specific embodiment

Further illustrate by reference to the accompanying drawings now implementation method of the present utility model, as Fig. 1, select the steel plate of 3 millimeters of thickness, make that length equates with elephant trunk 2 sidewall width, width is that the rectangular slab bar of 25 millimeters is as fin 3, on the madial wall of elephant trunk 2, the parallel parallel lines that draw 200 millimeters, interval, make two templates that wedge angle is 70 degree, be placed on respectively between the two ends of fin 3 and the sidewall of elephant trunk 2, the inside sidewalls of elephant trunk 2 is close on one side of template, the another side of the upper plane of fin 3 being close to template, by a side of fin 3 with rule and align, weld, successively by after fin 3 and elephant trunk inwall firm welding, just completed enforcement of the present utility model, in use procedure, when raw material falls while entering elephant trunk 2 from hopper 1, because fin 3 is acclivitous, the raw material of powdery can be welded on fin 3 on elephant trunk 2 sidewalls to be stopped and retains part material, when follow-up raw material falls again, just can not retained by fin 3, and the raw material of follow-up whereabouts, impact be to be deposited in the raw material on fin 3 and can not impact elephant trunk inwall, so just reduce the wearing and tearing of raw material to elephant trunk inwall, extended the service life of elephant trunk.

This example is in numerous embodiments preferred one, does not represent all technical schemes, and for example, fin 3 adopts riveted joint, and the fixing mode of screw is connected with elephant trunk 2.

Claims
