Description

Technical Field

[0001] This utility model belongs to the field of substrate glass production technology, specifically relating to an anti-bridging device for feeding broken glass. Background Technology

[0002] In the upstream process of raw material batching and conveying in glass production, a vibrating feeder is generally used to precisely control the raw material flow rate. Crushed glass, as a raw material, plays a crucial role in reducing melting temperature and energy consumption, promoting homogenization, stabilizing chemical reactions, and enabling closed-loop resource utilization. Therefore, maintaining a stable discharge of crushed glass from the substrate glass raw material is a critical task in the specialty glass manufacturing industry. In existing technologies, crushed glass is generally fed directly into the inlet of the vibrating feeder. This process is prone to bridging, hindering smooth entry into the melting furnace, making it impossible to control the feeding speed, and easily causing delays in subsequent processes. Furthermore, crushed glass bridging also leads to severe equipment wear and contamination of raw materials by impurities. Therefore, it is necessary to design an anti-bridging device for crushed glass feeding. Utility Model Content

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: This utility model provides an anti-bridging device for feeding crushed glass, including a feeding hopper, a vibration mechanism, a stirring mechanism, a crushing mechanism, and a magnetic sieve mechanism. The feeding hopper, the crushing mechanism, and the magnetic sieve mechanism are connected in sequence along the vertical direction.

[0017] See also Figure 1-5 This embodiment provides an anti-bridging device for feeding crushed glass, including a feeding hopper 1, a vibration mechanism 2, a stirring mechanism 3, a crushing mechanism 4, and a magnetic screen mechanism 5. The feeding hopper 1, the crushing mechanism 4, and the magnetic screen mechanism 5 are connected in sequence along the vertical direction. The vibration mechanism 2 is located on the outer wall of the feeding hopper 1. The stirring shaft 31 of the stirring mechanism 3 runs through the two side walls of the feeding hopper 1 and is located inside the feeding hopper 1. The magnetic screen mechanism 5 includes at least one magnetic grid plate 51 arranged facing the discharge port of the crushing mechanism 4.

[0018] In this embodiment, the feed hopper 1 is shaped like an inverted truncated pyramid, consisting of three side plates with a 70° inclination angle and one vertically arranged side plate. The large 70° inclination angle facilitates the downward flow of broken glass along the inner wall. The eccentric structure of the feed hopper 1 prevents the formation of bridges with uniform force when broken glass is fed in. An observation port 13 is provided on the vertical side plate of the feed hopper 1, and the observation port 13 is equipped with a detachable cover for easy observation of the wear condition of the cutter head 47 of the crushing mechanism 4 and for easy replacement of parts.

[0019] In this embodiment, the vibration mechanism 2 is a vibration motor installed on the outside of the two side plates of the feed hopper 1, used to solve the problem of broken glass sticking to the hopper wall. The stirring mechanism 3 is installed in the feed hopper 1 at a position where bridging is likely to occur, used to break up any possible bridging and allow the broken glass to fall smoothly. The stirring shaft 31 is driven by a motor (not shown). Several stirring blades 33 extending radially along the stirring shaft 31 are connected to the stirring shaft 31. The stirring blades 33 are spaced apart and have different orientations. Furthermore, several stirring rods 35 are spaced apart on the stirring blades 33, and the axis of any stirring rod 35 intersects the axis of the stirring blade 33 to which it is located.

[0020] In this embodiment, the crushing mechanism 4 includes a frame 41, two rotating shafts 43 mounted on the frame 41, and a parallel shaft gear pair 45 mounted at one end of the two rotating shafts 43. The two rotating shafts 43 are rotatably mounted on the frame 41 via bearings and are driven by a rotating motor (not shown). Each of the two rotating shafts 43 has a locating protrusion 431 protruding axially along its surface. Several cutter heads 47 and several cutter holders 49 are arranged sequentially at intervals on each rotating shaft 43, with each cutter head 47 of one rotating shaft 43 corresponding to each cutter holder 49 of the other rotating shaft 43, forming a double-roll crusher. The rotation speed can be adjusted according to the flow rate and particle size of the crushed glass by a frequency converter. Specifically, the cutter holders 49 are circular, and several support seats 491 are respectively installed on the two inner sidewalls of the frame 41 corresponding to the cutter holders 49 on opposite sides. The support seats 491 correspond one-to-one with the cutter holders 49. The cutter head 47 includes a circular main body 471 connected to the rotating shaft 43 and a plurality of sharp teeth 473 extending obliquely outward from the edge of the circular main body 471. The plurality of sharp teeth 473 are distributed circumferentially along the circular main body 471. Figure 3 As shown, the size of the sharp teeth 473 on the cutter head 47 is set according to the actual required size of the broken glass from the crushing mechanism 4. The cutter head of the crushing mechanism 4 is made of a magnetic wear-resistant material, such as high-chromium cast iron, to reduce wear and ensure that it can be attracted by the magnetic grid plate 51 during wear, preventing contamination of the raw materials.

[0021] In this embodiment, the magnetic screening mechanism 5 includes a housing 53 and three magnetic grid plates 51 disposed on the housing 53. The magnetic grid plates 51 are of a drawer-type design. The housing 53 includes an inverted truncated square shell connected to the discharge port of the crushing mechanism 4 and a box-type shell connected to the inverted truncated square shell. The magnetic grid plates 51 are arranged in a drawer-like manner on the box-type shell, and the pull-out structure makes it easy to clean the impurities adsorbed on the magnetic grid plates 51. The three-stage magnetic grid plates 51 installed at the lower end of the crushing mechanism 4 can enhance the impurity adsorption effect, better prevent iron filings generated by the wear of the crushing blades and hopper walls from entering subsequent processes, and ensure the cleanliness of the crushed glass raw materials.

[0022] The anti-bridging device in this embodiment is located before the vibrating feeder and includes a feeding hopper, a vibrating mechanism, a stirring mechanism, a crushing mechanism, and a magnetic screening mechanism. It can solve the bridging problem of crushed glass raw materials. Through the cooperation of multiple mechanisms, it can better cope with the comprehensive challenges brought about by the easy bridging, easy wear, and easy blockage of crushed glass feeding, and ensure the stable and uniform feeding of crushed glass raw materials. This is conducive to maintaining the stability of the melting process in the production process and ensuring the production quality of glass products. It is of great significance for improving the automation level and product quality of special glass production process.
