Abstract
The utility model provides a plate-type ladder bell mouth sieve, belongs to vibration screening machinery, has improved sifter intensity and has solved the problem in stifled hole. Comprising a frame, a tapered strip and a support plate. The frame is composed of two side plates and a row of parallel connecting rib plates uniformly arranged between the two side plates; a row of right-angled trapezoidal supporting plates are uniformly arranged between every two adjacent connecting rib plate supports, and a conical plate strip is arranged on each supporting plate; conical screen holes are formed between every two conical battens; a step is formed between every two rows of the conical battens; the screen surface of the whole screen plate is in a zigzag step shape. The sieve has the characteristics of high structural rigidity, wear resistance, impact resistance, long service life, high aperture ratio, no hole blockage, no blockage and high sieving efficiency. The vibrating screen can be applied to vibrating screening of large and medium irregular materials.
Description
Technical Field
The utility model belongs to the field of vibration screening machinery, mainly relate to shock resistance, not stifled hole and stand wear and tear for the board-like ladder bell mouth sieve of well bold material screening.
Background
The sieve plate of the existing vibrating sieve for sieving large materials has short service life, the abrasion of the sieve plate surface in sieving is quick, the integral rigidity of the sieve plate is weak, and the sieve plate is easy to break when being impacted by the large materials; because the sieve mesh of sieve is the bar sieve mesh of rectangle generally, not only the percent opening is lower, and the material is easy to block the hole, seriously influences the screening efficiency of shale shaker.
Disclosure of Invention
The utility model aims at providing a plate-type ladder bell mouth sieve, the structural rigidity of this sieve is high, the percent opening is high, do not block the hole, and screening efficiency is high.
The utility model discloses a realize through following technical scheme, including frame, toper lath and backup pad, characterized by: the frame is composed of two side plates and a row of parallel connecting rib plates uniformly arranged between the two side plates; a row of right-angled trapezoidal supporting plates are uniformly arranged between every two adjacent connecting rib plate supports, and a conical plate strip is arranged on each supporting plate; conical screen holes are formed between every two conical battens; a step is formed between every two rows of the conical battens; the screen surface of the whole screen plate is in a zigzag step shape.
The tapered strip is a wear-resistant tapered strip made of a wear-resistant material. The tapered sieve holes are formed in the way that the width of the sieve holes in the direction of the discharge end is larger than that of the sieve holes in the direction of the feed end. The number of the steps of the sieve plate is 2-10.
The utility model has the advantages that the tapered lath is fixed on the frame through the support plate, the structure rigidity is high, the tapered lath is wear-resistant and impact-resistant, and the service life is long; the structure principle of the conical sieve pores is advanced, and the aperture ratio is high; the material does not block holes and block when running on the screen surface, and the screening efficiency of the vibrating screen during working is improved. The vibrating screen can be applied to vibrating screening of large and medium irregular materials.

Detailed Description
The following description of the embodiments of the present invention refers to the accompanying drawings:
comprising a frame, a tapered slat 2 and a support plate 3. The frame is composed of two side plates 4 and a row of parallel connecting rib plates 1 uniformly arranged between the side plates 4; a row of right-angled trapezoidal supporting plates 3 are uniformly arranged between every two adjacent connecting rib plates 1, and a wear-resistant tapered strip 2 is arranged on each supporting plate 3; conical screen holes 5 are formed between every two conical battens 2; a step is formed between every two rows of the conical battens 2; the screen surface of the whole screen plate is in a zigzag step shape. The conical strip 2 is a wear-resistant conical strip made of an NM550 wear-resistant plate; the width of the conical sieve holes 5 in the discharge end direction is larger than that in the feeding end direction; the number of steps of the screen deck is 4. The figure shows a plate-type stepped tapered hole sieve plate with the length of 1218mm and the width of 592mm, wherein the width b =40mm, a =50mm of the tapered sieve hole 5, the width c =30mm and the width d =20mm of the tapered lath 2.
