Description

Technical Field

[0001] The invention relates to the technical field of drying processing for ternary precursor production, and in particular to drying equipment for ternary precursor production. Background Art

[0002] During the processing of ternary precursors, the materials after drying and separation need to be further dried by corresponding drying equipment. At present, most of the equipment used for drying ternary precursors is a disc dryer.

[0003] The existing disc dryer generally includes a fixed tank body and a number of heating plates arranged at different heights in the fixed tank body. The material enters the heating plate at the top through the guide hopper, and the scraper arranged on the upper part of the heating plate is driven by the corresponding driving mechanism. Under the rotation of the scraper, the material on the heating plate is gradually shoveled outward or inward alternately, so that the material can pass through the surface of each heating plate in sequence, thereby achieving a better drying effect. Such a disc dryer has the following defects in actual use: 1) The position of the scraper is fixed during the process of shoveling and pushing the material, so the material can only be shoveled outward in a pile, resulting in insufficient uniformity of contact between the material and the heating plate, thereby affecting the drying effect of the material; 2) The material enters the heating plate at the top in a pile, resulting in insufficient uniformity of the material during the shoveling process, thereby further affecting the drying effect of the material.

[0004] Therefore, the research purpose of the present invention is to design a drying equipment for ternary precursor production that can effectively break up the material during the shoveling process to improve the contact uniformity and contact rate between the material and the heating plate; and can ensure the uniformity of material discharge to improve the uniformity of the material in the subsequent shoveling process. Summary of the invention

[0012] The scraper driving mechanism includes a plurality of circles of magnet sheets which are fixedly connected to the upper sides of the first heating plate and the second heating plate in an annular array at intervals, and the magnet sheets are respectively arranged corresponding to the first scraper and the second scraper. When the first scraper and the second scraper rotate and pass the position where the magnet sheets are located, the first scraper and the second scraper are adsorbed, and the first limit spring and the second limit spring are compressed. When the compression force of the first limit spring and the second limit spring is greater than the adsorption force of the magnet sheet, the first scraper and the second scraper leave the position where the magnet sheet is located, and swing under the elastic force of the first limit spring and the second limit spring, so as to break up the material when scraping it.

[0022] Advantages of the present invention:

[0023] 1) While improving the structure of the first scraper mechanism and the second scraper mechanism, the present invention adds a scraper drive mechanism, which includes a plurality of magnet sheets that are fixedly connected to the upper side of the first heating plate and the second heating plate in a circular array at intervals. When the first scraper and the second scraper rotate and pass the position of the magnet sheet, the first scraper and the second scraper are adsorbed, and the first limit spring and the second limit spring are compressed. When the compression force of the first limit spring and the second limit spring is greater than the adsorption force of the magnet sheet, the first scraper and the second scraper leave the position of the magnet sheet and swing under the elastic force of the first limit spring and the second limit spring, so as to break up the material when scraping it. Therefore, the material can be effectively broken up synchronously during the process of shoveling and pushing the material, so as to improve the contact uniformity and contact rate between the material and the heating plate, thereby effectively improving the drying effect of the material.

[0024] 2) The fixed tank body in the middle of the material hopper of the present invention is fixedly connected with a corresponding material guide cone, and multiple corresponding material discharge ports are evenly distributed on the periphery of the material guide cone and the fixed tank body between the material guide cones. Under the action of the material guide cone, the material entering the material hopper is dispersed and discharged, thereby ensuring the uniformity of material discharge, improving the uniformity of the material in the subsequent shoveling process, and further effectively improving the drying effect of the material.

[0025] 3) A corresponding fixed ring plate is fixedly connected to the bottom side of the top of the fixed tank body of the present invention, and a corresponding annular feeding trough is movably installed on the inner side of the fixed ring plate. The bottom surface of the annular feeding trough is evenly distributed with many corresponding feeding holes. During the rotation of the driving shaft, the driving block arranged on the driving shaft gradually pushes the convex block connected to the annular feeding trough to drive the annular feeding trough to vibrate. In this way, the material after feeding can be further dispersed to ensure the uniformity of material feeding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings:

[0034] refer to Figure 1-6 , a drying device for producing a ternary precursor, comprising:

[0035] A fixed tank body 1, a corresponding lower hopper 2 is arranged on the top of the fixed tank body 1, and a discharge pipe 101 is arranged on the bottom of the fixed tank body 1; a first heating plate 3 and a second heating plate 4 are arranged alternately in height in the fixed tank body 1, corresponding guide holes 5 are arranged in the middle of the first heating plate 3 and the second heating plate 4 respectively, the periphery of the second heating plate 4 is extended and arranged outside the first heating plate 3, and the guide hole diameter of the first heating plate 3 is smaller than the guide hole diameter of the second heating plate 4;

[0036] The scraper driving mechanism 6 comprises a driving shaft 601 which penetrates through the guide hole 5 of the first heating plate 3 and the second heating plate 4, and the driving shaft 601 is driven by a corresponding driving motor 602;

[0037] The first scraping mechanism 7 comprises first fixed rods 701 fixed to the driving shaft 601 on the upper side of the first heating plate 3 in an annular array, and a plurality of corresponding first fixed shafts 702 are fixedly connected side by side downward to the first fixed rods 701, and first scrapers 703 for scraping the material on the first heating plate 3 outward are rotatably mounted on the first fixed shafts 702, and the first scrapers 703 and the first fixed shafts 702 are limited by corresponding first limit springs 704;

[0038] The second scraper mechanism 8 comprises a second fixed rod 801 fixed to the driving shaft 601 on the upper side of the second heating plate 4 in an annular array, a plurality of corresponding second fixed shafts 802 are fixedly connected side by side downward to the second fixed rod 801, and second scrapers 803 for scraping the material on the second heating plate 4 inwardly are rotatably mounted on the second fixed shafts 802, and the second scrapers 803 and the second fixed shafts 802 are limited by corresponding second limit springs 804;

[0039] The scraper driving mechanism 9 includes a plurality of circles of magnet sheets which are fixedly connected to the upper sides of the first heating plate 3 and the second heating plate 4 at intervals in a circular array. The magnet sheets are respectively arranged corresponding to the first scraper 703 and the second scraper 803. When the first scraper 703 and the second scraper 803 rotate and pass through the position where the magnet sheets are located, the first scraper 703 and the second scraper 803 are adsorbed, and the first limit spring 704 and the second limit spring 804 are compressed. When the compression force of the first limit spring 704 and the second limit spring 804 is greater than the adsorption force of the magnet sheets, the first scraper 703 and the second scraper 803 leave the position where the magnet sheets are located, and swing under the elastic force of the first limit spring 704 and the second limit spring 804, so as to break up the material when scraping it.

[0040] The present invention improves the structure of the first scraper mechanism 7 and the second scraper mechanism 8, and adds a scraper driving mechanism 9.

Therefore, the material can be effectively broken up synchronously during the process of shoveling and pushing the material, so as to improve the contact uniformity and contact rate between the material and the heating plate, thereby effectively improving the drying effect of the material.

[0041] A corresponding material guide cone 10 is fixedly connected to the fixed tank body 1 in the middle of the material hopper 2, and a plurality of corresponding material discharge ports 11 are evenly distributed on the periphery of the material guide cone 10 and the fixed tank body 1 between the material guide cone 10.

The bottom surface of the annular feeding trough 13 is evenly distributed with many corresponding feeding holes; the inner side of the annular feeding trough 13 is evenly distributed with a plurality of corresponding protrusions 14, and a driving block 15 adapted to the protrusion 14 is fixedly connected to the driving shaft 601. During the rotation of the driving shaft 601, the driving block 15 gradually blocks and pushes the protrusion 14 to drive the annular feeding trough 13 to vibrate. During the rotation of the driving shaft 601, the driving block 15 arranged on the driving shaft 601 gradually blocks and pushes the protrusion 14 connected to the annular feeding trough 13 to drive the annular feeding trough 13 to vibrate. In this way, the material after feeding can be further dispersed to ensure the uniformity of material feeding.

[0043] The outer side of the annular material discharge chute 13 is connected to the fixed ring plate 12 via a plurality of connecting springs 16 .

[0044] The first heating plate 3 and the second heating plate 4 are respectively hollow, and one side of the first heating plate 3 and the second heating plate 4 are respectively connected to the corresponding hot air inlet pipe 18 through the corresponding air intake duct 17, and the other side of the first heating plate 3 and the second heating plate 4 are respectively connected to the corresponding exhaust pipe 20 through the corresponding exhaust duct 19.

[0045] The magnet sheets are respectively fixedly embedded in the top and bottom sides of the first heating plate 3 and the second heating plate 4. The peripheries of the first heating plate 3 and the second heating plate 4 are respectively fixedly connected to the fixed tank body 1 through corresponding connecting rods.

[0046] A circle of corresponding first material baffle plates 21 is fixedly connected to the guide hole of the first heating plate 3 and tilted inward.
