Description

Technical Field

[0001] This utility model relates to the field of glass bottle recycling equipment, and in particular to a device for recycling defective products used in glass bottle production and processing. Background Technology

[0002] In the glass industry, defective glass bottles have a scrap rate of about 3%-5% due to molding defects, bubbles, or dimensional deviations. Recycling, crushing, and reuse can significantly reduce raw material consumption.

[0003] Existing glass bottle crushing equipment mainly uses hammer crushers, which achieve crushing through high-speed hammer impact. The single machine has a processing capacity of 5-8 tons / hour, but the output particle size distribution is wide. It is necessary to match the multi-stage screening system to optimize the particle size, which makes the equipment occupy a large area. Large particles that do not meet the standards need to be returned to the crusher for re-crushing, which indirectly increases the material rework rate. Utility Model Content

[0004] The purpose of this utility model is to provide a defective product recycling device for glass bottle production and processing, which solves the problems of the inability to integrate the crushing and screening equipment of defective glass bottles to save floor space and the high material rework rate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A defective product recycling device for glass bottle production and processing includes a cylindrical body. An upward-opening feed inlet is fixed to the upper part of the outer wall of the body, and a discharge outlet is fixed to the bottom. A filter cylinder is coaxially fixed inside the body, and screening holes are distributed on the outer wall of the filter cylinder. A central shaft is mounted inside the body via bearings. Movable sealing plates are provided at the openings at both ends of the filter cylinder, and the sealing plates are fixed to the central shaft. Multiple pressure rollers are evenly distributed circumferentially between the two sealing plates, and the two ends of the pressure rollers are connected to the sealing plate shaft. A motor is fixed outside the body and is linked to the central shaft via a pulley system.

[0007] Preferably, planetary gears are distributed on the outer sides of the two sealing plates and are fixed coaxially with the pressure rollers. Gear rings are fixed at the front and rear ends of the machine body, and the planetary gears mesh with the gear rings.

[0008] Preferably, the pressure roller has crushing spikes distributed around its circumference, and the crushing spikes correspond to the positions of the screening holes during rotation.

[0009] Preferably, a material feeding plate is radially fixed to the central shaft.

[0010] Preferably, the feeding plate includes a fixed plate and a telescopic plate. The fixed plate is fixed to the central shaft and has a telescopic groove on its outer side. The telescopic plate is slidably connected along the telescopic groove.

[0011] Preferably, a spray pipe in the front-to-back direction is fixed at the top of the machine body, and spray heads are distributed at the bottom of the spray pipe.

[0012] Preferably, a telescopic plate is provided inside the feed inlet, and the top of the telescopic plate is installed to the inner wall of the feed inlet by a hinge, so as to block the feed inlet by its own weight.

[0013] Preferably, the outer wall of the machine body is supported by support legs.

[0014] Preferably, a horizontal receiving groove is placed on the support leg, and the receiving groove is located directly below the discharge port.

[0015] Preferably, the bottom surface of the receiving trough has a water filter hole.

[0016] This utility model has the following beneficial effects:

[0017] 1. By driving multiple pressure rollers to rotate inside the filter cylinder, the glass bottles inside the filter cylinder can be crushed efficiently. The crushed and qualified granular materials can be screened out through the screening holes, realizing the integrated crushing and screening function of the equipment, reducing the equipment footprint and reducing the material rework rate.

[0018] 2. Through the cooperation of planetary gears and gear rings, the pressure roller can achieve a combined revolution and rotation motion driven by the central shaft, which greatly improves the crushing efficiency of glass bottles. In addition, with the help of crushing nails, a shearing crushing effect is formed, which further increases the crushing strength of the pressure roller and can also press out the crushed material stuffed into the sieve hole, eliminating the need for manual cleaning.

[0019] 3. When a glass bottle breaks, the dust baffle can prevent dust from escaping from the discharge port, increase the machine's sealing, and work with the spray pipe and spray head to reduce dust and minimize the harm to the human body. Attached Figure Description

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1-6 As shown in this embodiment, a defective product recycling device for glass bottle production and processing adopts a double-layer cylindrical structure. The outer body 1 and the inner filter cylinder 4 are arranged coaxially. The outer wall of the filter cylinder 4 is distributed with screening holes 41. The body 1 and the filter cylinder 4 are made of 304 stainless steel, and the distance between them is maintained at 80-100mm to ensure that the broken glass fragments can be effectively classified. The upper part of the outer wall of the body 1 is fixed with an upward-sloping feed port 2 so that the glass bottles can slide in automatically. The bottom is fixed with a discharge port 3 to discharge the broken material. The body 1 is equipped with bearings. Equipped with a central shaft 5, the filter cylinder 4 has movable sealing plates 6 at both ends of its openings. The sealing plates 6 are fixed to the central shaft 5. Multiple pressure rollers 7 are evenly distributed around the circumference between the two sealing plates 6. The two ends of the pressure rollers 7 are connected to the shaft of the sealing plates 6. The distance between the pressure rollers 7 and the filter cylinder 4 is 2-5mm, which allows the sheet glass to be crushed. The machine body 1 is equipped with a 7.5kW variable frequency motor 9, which drives the central shaft 5 through a pulley group 8 consisting of a V-belt and pulleys. It is equipped with an overload protection device, so that the central shaft 5 drives the sealing plates 6 and pressure rollers 7 to rotate and crush the glass bottle.

[0030] Furthermore, planetary gears 10 are distributed on the outer sides of the two sealing plates 6 and are fixed coaxially. Gear rings 11 are fixed at the front and rear ends of the machine body 1, and the planetary gears 10 mesh with the gear rings 11. This achieves a combined revolution and rotation motion of the pressure roller 7.

[0031] The pressure roller 7 is inlaid with tungsten steel crushing nails 12 around its circumference. During rotation, the crushing nails 12 correspond to the positions of the screening holes 41, forming a shearing and crushing effect on the glass fragments. They can also press out the fragments that are stuffed into the screening holes, eliminating the need for manual cleaning.

[0032] Furthermore, a material-pulling plate 13 is radially fixed to the central shaft 5. This plate can agitate the glass fragments accumulated at the bottom of the filter cylinder 4, preventing excessive accumulation of glass fragments, changing the position of the glass fragments, and accelerating the crushing efficiency.

[0033] Specifically, the feeding plate 13 includes a fixed plate 131 and a telescopic plate 132. The fixed plate 131 is fixed to the central shaft 5 and has a telescopic groove 133 on its outer side. The telescopic plate 132 is slidably connected within the telescopic groove 133. When the telescopic plate 132 rotates to a higher position, it can slide into the telescopic groove 133 by its own weight, pushing the glass fragments to a higher position and scattering them into the filter cylinder 4, making the glass fragments more dispersed and further improving the crushing efficiency.

[0034] Furthermore, a front-to-back spray pipe 14 is fixed to the top of the machine body 1, and a water pump is connected to the spray pipe 14 to supply water. Spray heads 15 are distributed at the bottom of the spray pipe 14. This serves to reduce dust when the glass inside the machine body 1 breaks, preventing excessive dust generated by the glass bottle breakage from drifting out of the machine body 1 and being absorbed by the human body.

[0035] A telescopic plate 132 is provided inside the feed inlet 2. The top of the telescopic plate 132 is installed to the inner wall of the feed inlet 2 via a hinge 17, and the feed inlet 2 is sealed by its own weight. This increases the sealing performance of the machine body 1 and further reduces the amount of dust discharged from the machine body 1.

[0036] Specifically, the outer wall of the machine body 1 is supported by support legs 18. A horizontal receiving trough 19 is placed on the support legs 18, and the receiving trough 19 is located directly below the discharge port 3. It is used to collect the crushed and screened particles. The bottom surface of the receiving trough 19 has filter holes 20. The diameter of the filter holes 20 is much smaller than that of the screening holes 41, so that the water droplets sprayed from the spray head 15 can be concentrated and dripped out, realizing dry and wet separation.

[0037] The working principle of this utility model is as follows: The defective glass bottle to be processed slides into the machine body 1 through the upward-sloping feed inlet 2. The telescopic plate 132 built into the feed inlet 2 seals the inlet by its own weight, ensuring continuous feeding while reducing dust spillage. The motor 9 drives the central shaft 5 to rotate via the pulley group 8, which in turn drives the two side sealing plates 6 to rotate and causes the pressure roller 7 to revolve. Because the planetary gear 10 on the outer side of the sealing plate 6 meshes with the fixed gear ring 11, the pressure roller 7 rotates synchronously during its revolution, forming a "planetary" compound motion. The crushing nails 12 embedded on the surface of the pressure roller 7, as it rotates, intermittently shear with the screening holes 41 on the outer wall of the filter cylinder 4, producing crushing, impact, and shearing effects on the glass bottle, breaking the sheet glass into small particles. The feeding plate 13 on the central shaft 5 rotates with the shaft, and its telescopic plate 132 periodically extends and retracts under the action of centrifugal force and its own weight. When it rotates to the bottom of the filter cylinder, it extends, pushing the accumulated glass fragments to tumble; when it rises to a high position, it retracts, scattering the fragments to different areas of the filter cylinder. This action effectively prevents material accumulation, promotes uniform distribution of fragments and their contact with the crushing nails, and improves crushing efficiency. The spray pipe 14 sprays water mist into the filter cylinder 4 through the bottom spray head 15, suppressing the diffusion of glass dust generated during the crushing process. Particles smaller than the sieve hole 41 are mixed with sprayed water and discharged into the receiving tank 19 through the discharge port 3. The water is quickly discharged through the bottom filter holes 20, while the glass particles are retained and collected due to the difference in pore size.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
