Description

Technical Field

[0001] This invention relates to the post-rolling processing of materials, and more particularly to a material dispersion and homogenization device for a roller press. Background Technology

[0002] In cement production, materials need to be crushed by roller pressing and then lifted to designated equipment or storage tanks.

[0003] In practice, materials are refined through roller pressing and form a certain number and density of briquettes. The elevator includes a closed-loop pipe, a closed-loop chain rotating along the pipe, and several buckets spaced apart on the chain. The closed-loop pipe is vertically arranged, and the buckets circulate. The buckets at the lower end of the pipe are suitable for receiving material and then lifting it upwards. Therefore, if material containing a certain amount of briquettes is directly thrown into the elevator buckets, it can easily cause abnormal swaying of the buckets. Furthermore, briquettes may protrude from the buckets or even become stuck between the outer wall of the buckets and the inner wall of the closed-loop pipe, causing the elevator to jam and overload. Additionally, the material in the buckets may not be evenly distributed, resulting in unstable bucket ascent. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems mentioned above, and provides a material dispersing and homogenizing device for a roller press, which can disperse the material after roller pressing and simultaneously divide the material into multiple parts side by side. The loose and broken material continuously and steadily flows into the hopper of the elevator. The multiple parts of material are poured into the hopper side by side, and the material is evenly distributed in the elevator hopper, which facilitates the balanced and stable climbing of the hopper.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

The guide channel is adapted to receive material falling from the crushing structure of the roller press. The at least two opposing cone plates are distributed at intervals from top to bottom. Each opposing cone plate includes a pair of impact plates with opposite cone tips. The impact plates of adjacent opposing cone plates are staggered. In the vertical projection of the impact plates of adjacent opposing cone plates, the side edges of the impact plate projections overlap or splice together, so that the at least two opposing cone plates define an impact plate collection area. The impact plate collection area is adapted to be impacted by the material falling from the guide channel. The lowermost opposing cone plate is adapted to divide the material into two parts, so that the two parts of the material are arranged along the width direction of the outward conveyor belt.

The first corner block is suitable for pushing the bevel at one end of the conical plate. The inner wall of the other side wall is spaced apart from the other end of the conical plate. The reference push block is provided with a second corner block. The second corner block is suitable for penetrating the chassis and pushing the bevel at the other end of the conical plate. The reference push block is screwed to the outer side of the other side wall.

[0011] As an improvement to the above technical solution, it also includes two re-dividing plates, which respectively cut the two portions of material separated by the bottom conical plate, and the four portions of material cut by the two re-dividing plates are arranged along the width direction of the conveyor belt.

[0012] As an improvement to the above technical solution, it also includes a chassis, the inner wall of which is provided with a handle, both ends of the re-dividing plate are respectively supported by the corresponding handle, and at least one end of the re-dividing plate is spaced apart from the inner wall of the chassis.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figures 1 to 3This invention provides a material dispersing and homogenizing device for a roller press, including a guide channel 300 and at least two opposing cone plates 500. The guide channel 300 is adapted to receive the material falling from the roller press crushing structure 200. The at least two opposing cone plates 500 are distributed at intervals from top to bottom. Each opposing cone plate 500 includes a pair of impact plates 510 with opposite cone tips. The impact plates 510 of adjacent opposing cone plates 500 are staggered. In the vertical projection of the impact plates 510 of adjacent opposing cone plates 500, the side edges of the impact plate projections are superimposed or spliced, so that the at least two opposing cone plates 500 define an impact plate collection area. The impact plate collection area is adapted to be impacted by the material falling from the guide channel 300. The lowermost opposing cone plate 500 is adapted to divide the material into two parts, so that the two parts of the material are arranged along the width direction of the external conveyor belt 710.

[0036] Reference Figures 1 to 3 Two impact plates 510 with opposite cone tips are arranged on the cone plate 500, with the axial direction of the cone plate 500 being the direction of this arrangement; the impact plates 510 of two adjacent cone plates 500 are staggered, and the axial directions of two adjacent cone plates 500 are perpendicular. (Refer to...) Figures 1 to 3 The cone plate 500 also includes a mounting strip 520, with two impact plates 510 with opposite cone tips arranged at the upper end of the mounting strip 520.

[0037] Reference Figure 1 and Figure 2 In some embodiments, the dispersing and homogenizing device shares a housing 100 (base / frame) with the roller press, and the guide channel 300 and the conical plate 500 are installed inside the housing 100. The guide channel 300 can be presented as two inclined channels, or as a trough / funnel.

[0038] In actual production and sales, the dispersing and homogenizing device may or may not include the aforementioned external conveyor belt 710; refer to Figures 1 to 3 During installation, the arrangement direction line of the impact plate 510 of the lowest cone plate 500 (i.e., the axial direction of the cone plate 500) is perpendicular to the width direction of the conveyor belt 710. The lowest cone plate 500 is suitable for dividing the material into two parts, which are arranged along the width direction of the conveyor belt 710.

[0039] The operation process of the present invention is as follows: the material falling from the crushing structure 200 of the roller press flows to the material collection area of ​​the impact plate through the guide channel 300;

[0040] The material containing the patina is impacted by at least one impact plate 510, causing the patina to disperse and the material to become loose.

[0041] Reference Figures 1 to 3 , Figure 7 After the material impacts the material collection area of ​​the impact plate, it is divided into two parts, which are arranged along the width direction of the external conveyor belt 710.

[0042] It is understandable that the external conveyor belt 710 includes a conveyor belt, pulleys and a conveyor motor, with the pulleys driving the conveyor motor.

[0043] Compared with the prior art, the beneficial effects of this application include: the material output by the roller press crushing structure 200 is subjected to the action of at least two opposing cone plates 500 without consuming power or other resources, and is simultaneously broken up and differentiated; the loose material can easily and steadily fall into the conveyor belt 710 and the elevator bucket 720, the loose material is less likely to clog the elevator, the multiple materials separated and arranged side by side are evenly distributed on the conveyor belt 710, the elevator bucket 720 receives the relatively uniformly distributed material, the elevator bucket 720 with the uniformly distributed material can rise steadily, and the service life of the elevator is extended.

[0044] Reference Figures 1 to 3 Preferably, the casing 100 has several vertical reinforcing ribs on its perimeter wall. The conical plate 500 includes a mounting strip 520, which is a square tube. The conical plate 500 is lightweight and has high strength.

[0045] Reference Figures 1 to 3 , Figure 8 In some embodiments of the present invention, the impact plate 510 is provided with two crushing ramps 511, which define impact ridges 512. The impact ridges 512 correspond to the middle of the impact plate 510. The crushing ramps 511 are inclined outward along the side of the impact plate 510, and are suitable for breaking up materials. When the material cake hits the impact plate 510, the impact ridges 512 are suitable for dividing the material cake into two parts. The material cake hits the crushing ramps 511, and each part of the material cake contacts the crushing ramps 511 in sequence and breaks up in sequence.

[0046] In some embodiments of the present invention, the crushing inclined surface 511 is provided with a plurality of alternating tetrahedral pyramids, the bases of which overlap with the crushing inclined surface 511, and one side of each tetrahedral pyramid faces the side of the impact plate 510. In this invention, the tetrahedral pyramids facilitate the full and rapid loosening of the material cake, reducing the number of cone plates 500 required. The other two sides of the tetrahedral pyramids are simultaneously adapted to guide the material flow. It is understood that the material impacts the cone plates 500, making it difficult for material to remain on the crushing inclined surface 511 and the tetrahedral pyramids. In some embodiments, the plurality of tetrahedral pyramids are arranged in an array on the crushing inclined surface 511.

[0047] Reference Figures 1 to 3In some embodiments of the present invention, a chassis 100 and a reference push block 530 are also included. A pair of side walls of the chassis 100 corresponding to the two ends of the cone plate 500 are provided with a support platform 110 suitable for supporting the cone plate 500. A bevel 521 is opened at both ends of the cone plate 500. In the pair of side walls, a first corner block 120 is integrally formed on the inner side of one side wall. The first corner block 120 is suitable for pushing the bevel 521 at one end of the cone plate 500. An installation hole 130 is opened on the other side wall. The inner wall of the other side wall is spaced apart from the other end of the cone plate 500. The reference push block 530 is provided with a second corner block 531. The second corner block 531 is suitable for penetrating the chassis 100 and pushing the bevel 521 at the other end of the cone plate 500. The reference push block 530 is screwed to the outer side of the other side wall. Understandably, the second corner block 531 is adapted to pass through the mounting hole 130 and push against the other end bevel 521 of the cone plate 500. In this invention, the cone plate 500 is horizontally and axially positioned, and the cone plate 500 is easier to install and remove in the housing 100, reducing the labor intensity of maintenance workers in the housing 100.

[0048] Reference Figures 1 to 3 In some embodiments of the present invention, two re-dividing plates 600 are further included. The two re-dividing plates 600 respectively divide the two portions of material separated by the lowermost conical plate 500, and the four portions of material cut by the two re-dividing plates 600 are arranged along the width direction of the conveyor belt 710. Therefore, the conveyor belt 710 and the elevator hopper 720 further homogenize the material distribution and improve the stability of the operation of the conveyor belt 710 and the elevator.

[0049] Reference Figures 1 to 3 Preferably, the sub-plate 600 includes a beam strip and an inclined plate body, the inclined plate body being disposed at the upper end of the beam strip, the beam strip being a square tube; more preferably, the inclined plate body is connected to the beam strip by several reinforcing plates.

[0050] Reference Figure 3 In some embodiments of the present invention, a chassis 100 is also included, the inner wall of the chassis 100 is provided with a handle 140, the two ends of the sub-plate 600 are respectively supported by the corresponding handle 140, at least one end of the sub-plate 600 is spaced apart from the inner wall of the chassis 100, and the sub-plate 600 is easy to disassemble and assemble.

[0051] Reference Figure 2 , Figures 4 to 6In some embodiments of the present invention, the device further includes a housing 100 and two vertically distributed and axially perpendicular ratchet rollers 400. The ratchet rollers 400 are rotatably connected to the housing 100. The ratchet rollers 400 are provided with two ratchet groups. Each ratchet group includes multiple rows of ratchets spaced apart along the axial direction of the ratchet rollers 400. Each row of ratchets includes multiple ratchets 410 spaced apart along the circumference of the ratchet rollers 400. The length of the ratchets 410 in both ratchet groups gradually increases outward along the axial direction of the ratchet rollers 400. The two ratchet rollers 400 define a material dispersing recess 420 through the four ratchet groups. The material dispersing recess 420 is suitable for receiving the material flowing down from the guide channel 300. The material falling from the guide channel 300 is suitable for being dispersed by the ratchet rollers 400, shaken by the material dispersing recess 420, and / or agitated by the material dispersing recess 420. The material impact plate collection area is located below the material dispersing recess 420. In this invention, the guide channel 300 introduces the material containing the brittle into the material dispersion recess 420. The material containing the brittle is confined within the material dispersion recess 420 and cannot overflow. The material dispersion recess 420 is defined by a plurality of ratchet bars 410, allowing the material to be fully and effectively dispersed. The material impacts the material dispersion recess 420, driving the ratchet roller 400 to rotate to a certain extent. The material dispersion recess 420 persists and refreshes the ratchet bars 410 at its bottom. Material is unlikely to remain on the peripheral wall of the spindle of the ratchet roller 400. It is understood that the ratchet roller 400 rotates based on the impact of the material, and this rotation is non-directional, generally exhibiting small-amplitude repetitive rotation. This invention requires no power consumption while fully and effectively dispersing the material.

[0052] Reference Figure 2 , Figure 4 and Figure 5 In some embodiments of the present invention, the discharge nozzle of the guide channel 300 is inserted into the material dispersing recess 420. The connection between the ratchet roller 400 and the housing 100 is relatively away from the material dispersing recess 420 to prevent material dust from getting stuck at the connection and to ensure the rotational freedom of the ratchet roller 400.

[0053] In some embodiments of the present invention, the housing 100 is equipped with a bulk material motor suitable for driving the ratchet roller 400 to rotate, and the rotational speed W of the bulk material motor driving the ratchet roller 400 is W<0.2r / s (W is less than 0.2 revolutions per second).

[0054] In some embodiments of the present invention, a bearing housing 430 and a motor housing are also included. The bearing housing 430 is inserted into the housing 100 from the outside in. The bearing housing 430 mounts the end of the ratchet roller 400 via a bearing. The motor housing is connected to the bearing housing 430 or the housing 100. The shaft of the bulk material motor is inserted into the end of the ratchet roller 400. The bulk material motor is connected to the end of the ratchet roller 400 via a key. The bulk material motor is provided with a limiting recess suitable for limiting the key. In the present invention, the assembly and disassembly of the bulk material motor and the ratchet roller 400 are relatively convenient.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
