Description

Technical Field

[0001] The invention belongs to the field of Jun porcelain production, and specifically relates to a coarse crushing device, and in particular to a raw material coarse crushing device for Jun porcelain production. Background Art

[0002] Jun porcelain is a national geographical indication product of China. Jun porcelain originated in the Tang Dynasty and flourished in the Song Dynasty. It is one of the five famous porcelains in ancient China and is famous for the magical kiln changes produced by its unique glaze and firing method. As an important symbol in the history of Chinese ceramic art, Jun porcelain occupies an important position in the history of world ceramic development. Since ancient times, there have been sayings such as "gold has a price, but Jun is priceless" and "a piece of Jun porcelain is worth a million dollars". Its unique kiln-change art is widely loved by ceramic lovers for its artistic characteristics of "one color in the kiln, and thousands of colors out of the kiln".

[0003] The outstanding technological achievements of the Jun kiln are based on the scientific matching of the body and glaze, the reasonable control of the changes in the flame atmosphere during the firing process, and the use of oxidation and reduction atmospheres to create kiln-changed colors of varying depths from the same glaze and color. The Jun porcelain art has a unique national style and unique artistic characteristics, reflecting the great spirit and magnificent national culture of the Chinese nation. Therefore, it is well-known in the porcelain industry and is famous both at home and abroad. Although it has experienced ups and downs, it has remained enduring.

[0004] When Jun porcelain is produced, its raw materials must first be processed. Raw material processing generally includes: material selection, looking for raw materials with reliable performance, stable quality, and suitable for kiln change of Jun porcelain in the mining area, and carefully selecting them;

[0005] The raw materials must be processed as necessary, and the porcelain clay must be piled up in an open-air material yard for long-term, continuous cycles of wind, sun, rain and freezing to weather and soften it and improve its performance. The ore must be coarsely crushed into sand or powder by a wheel mill, and some must be shaded, rainproofed, dustproofed, etc.; finely ground, various raw materials are loaded into the ball mill according to the proportion and rotated to become mud or glaze that meets the quality requirements.

[0006] In the existing coarse crushing process of Jun porcelain raw materials, the traditional coarse crushing device for Jun porcelain raw materials generally uses a unidirectional rotating crushing mechanism. When the raw materials are crushed to a certain shape and continue to be subjected to a force in a single direction, it is difficult to further break them up, resulting in a decrease in crushing efficiency.

[0041] Using method of the device: When the device is in use, the raw materials to be coarsely crushed are added from the feed trough to the space between the crushing cover and the crushing core, and the cone crushing motor, the driving motor, the screening motor and the discharging motor are started. The cone crushing motor is started to drive the crushing cover to rotate through the gear and the gear ring. The crushing cover rotates and, under the interaction of the crushing teeth and the crushing core inside it, the raw materials are crushed once, so that the raw materials are crushed into smaller blocks. The crushed raw materials fall into the aggregate trough A, and continue to fall to the middle of the roller group after passing through the aggregate trough A. The driving motor drives the roller group and the crushing roller to rotate and operate through the transmission belt. The roller group operates to perform secondary crushing on the raw materials that fall between the roller groups, and the raw materials are crushed into smaller specifications. The raw materials that are crushed by the roller group fall into the aggregate trough B, and continue to fall between the crushing roller and the crushing plate after passing through the aggregate trough B. The crushing roller operates and cooperates with the crushing plate to further crush the raw materials that fall between the crushing roller and the crushing plate, thereby completing Three-stage crushing. The three-stage crushing mechanism of this device has a strong crushing effect and high crushing efficiency. It can crush the falling raw materials step by step. When the position of the raw materials changes during the falling process, the raw materials can be crushed in multiple directions to further enhance the crushing effect. After crushing, the raw materials continue to fall and fall into the screening bucket. The screening motor drives the transmission rod through the eccentric wheel to drive the screening bucket to perform a cyclic reciprocating motion. The screening bucket is a screening bucket with a slope. While performing the cyclic reciprocating motion, the screening bucket screens the raw materials inside it. The qualified raw materials fall to the conveyor belt and are transported to the outside of the supporting body by the conveyor belt. The unqualified raw materials move to the receiving trough through the discharge trough under the action of the screening bucket, and then the unqualified raw materials are taken out from the receiving trough and crushed again, thereby completing the crushing and screening of the raw materials. This device has a screening mechanism, which can screen out the raw materials that do not meet the crushing standards, thereby ensuring the quality of the crushed raw materials.

A sliding ridge 407 is provided at the side of the sub-screening bucket 404. The sliding ridge 407 of the sub-screening bucket 404 passes through the sliding groove 108 and is placed above the supporting ball 109. The sliding groove facilitates the installation of the sliding ridge, and the supporting ball is used to reduce the friction of the sliding ridge, thereby reducing the resistance of the sub-screening bucket during reciprocating motion. The sub-screening bucket 404 includes a bucket body 408 and a screen 409, and the screen 409 is bolted to the bottom of the bucket body 408. The screen can be replaced according to the crushing specifications of the raw materials by the crushing plate and the crushing roller, making it more practical. The sub-screening bucket 404 is a sub-screening bucket 404 with a slope, and its end close to the eccentric wheel 402 is higher than the end of the discharge chute 406, which is convenient for screening raw materials that do not meet the crushing specifications.

[0046] See also Figure 3 The outer wall of the fixing frame 101 is provided with a placing support 110, and the edge of the receiving trough 405 is provided with a placing convex strip 410.

[0047] How to use the device: When the device is in use, the scraper plates arranged on both sides of the roller group can clean the roller group and scrape off the raw materials attached to the upper side to ensure the crushing effect of the roller group. The funnel-shaped collecting trough is more convenient for the raw materials to fall and prevents the material from being stuck. The stripes on the crushing plate and the crushing roller can enhance the crushing effect. The crushing plate of the device can adjust the distance with the crushing roller as needed, so as to achieve the technical effect of controlling the crushing specifications. The device also uses support balls to reduce the friction of the sub-screening bucket during operation, so that the sub-screening bucket can run more smoothly, and the screen can be replaced, and raw materials of various crushing specifications can be screened, which has strong practicality and applicability.
