Abstract
Description
Technical Field
[0001] This utility model belongs to the field of glass recycling technology, specifically a glass waste grinding device. Background Technology
[0002] Waste glass bottles are chemically stable and do not easily decompose automatically. Accumulated waste glass bottles cause environmental pollution. Collecting waste glass bottles, crushing them, and grinding the broken glass into powder can be added to raw materials to make new glass bottles or other glass products, which has a good recycling function.
[0003] Existing glass sheet toner devices mostly feature multiple grinding zones to achieve good grinding results. However, these multiple grinding mechanisms share the same feed inlet. In reality, the glass particles to be ground vary in size and require different degrees of grinding. Since they all enter through the same feed inlet, all glass particles have to pass through all grinding zones. This not only reduces the grinding efficiency of the glass but also increases unnecessary grinding movements, affecting the grinding effect and increasing the wear rate of the grinding mechanism. Therefore, it is necessary to develop a glass sheet waste grinding device to address the shortcomings of existing technologies. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 4As shown, this utility model provides a glass waste grinding device, including a multi-stage grinding cylinder 1. The multi-stage grinding cylinder 1 is equipped with a multi-stage grinding mechanism inside. A drive motor 2 is installed at the top of the multi-stage grinding cylinder 1. The lower end of the drive motor 2 extends into the interior of the multi-stage grinding cylinder 1 and is connected to the multi-stage grinding mechanism. A graded feeding component 3 is installed on one side of the outer surface of the multi-stage grinding cylinder 1. An adjustment component 4 is installed inside the graded feeding component 3. A discharge port 5 is connected to the bottom of the graded feeding component 3.
[0025] The grading feeding assembly 3 includes a feeding rack 31 fixedly installed on the outer surface of the multi-stage grinding cylinder 1. A feeding bin 32 is provided in the middle of the feeding rack 31. A plurality of evenly distributed grading feed inlets 33 are provided on the outer surface of the feeding rack 31 near the multi-stage grinding cylinder 1. The plurality of grading feed inlets 33 correspond one-to-one with the multi-stage grinding mechanism in the multi-stage grinding cylinder 1 and are interconnected. A grading filter screen plate 34 is slidably engaged inside the feeding bin 32 and the grading feed inlets 33. The bottom of the grading filter screen plate 34 abuts against a positioning component 35. The lower end of the positioning component 35 is connected to the inner wall of the feeding bin 32. Due to the setting of the feeding rack 31, with the cooperation of the feeding bin 32, the glass fragments poured in can be filtered step by step through the plurality of grading filter screen plates 34, so that glass fragments of the corresponding size can directly enter the corresponding grinding area. This can improve the grinding efficiency and reduce the wear rate of the grading grinding mechanism, thereby significantly improving the service life and grinding effect of the existing grading grinding mechanism.
[0026] The outer surface of the grading filter screen plate 34 is sealed and fitted to the inner wall of the feeding bin 32 and the grading inlet 33. The outer surface of the grading filter screen plate 34 is smooth and covered with filter holes. The grading filter screen plate 34 is inclined and the horizontal plane of one end of the grading filter screen plate 34 in the feeding bin 32 is higher than the horizontal plane of the other end.
[0027] Among them, the filter holes in several graded filter screen plates 34 have different inner diameters. The inner diameter of the filter holes in the upper graded filter screen plate 34 is larger than that in the lower graded filter screen plate 34. The inner walls of the filter holes in the graded filter screen plate 34 are smooth, and the inner diameter at the upper end is smaller than that at the lower end.
[0028] The positioning component 35 includes a positioning frame 351 fixedly installed below the grading filter screen plate 34. A limiting slide rod 352 is movably sleeved inside the positioning frame 351. The axes of the positioning frame 351 and the limiting slide rod 352 are parallel to the axis of the inner cavity of the feeding bin 32. The upper end of the limiting slide rod 352 passes through the positioning frame 351 and is fixedly connected to the bottom of the grading filter screen plate 34. The lower end of the limiting slide rod 352 extends to the bottom of the positioning frame 351. Since the positioning frame 351 and the limiting slide rod 352 are parallel to the feeding bin 32, they can provide good support for the grading filter screen plate 34, ensuring that the grading filter screen plate 34 can always be sealed and fitted against the inner wall of the feeding bin 32 when it moves up and down. At the same time, it can effectively reduce the wear intensity between the outer surface of the grading filter screen plate 34 and the inner wall of the feeding bin 32.
[0029] The limiting slide bar 352 is externally equipped with a positioning spring 353. The upper end of the positioning spring 353 is connected to the bottom of the grading filter screen plate 34, and the lower end of the positioning spring 353 is connected to the top of the positioning frame 351. Due to the positioning component 35, under the elastic support of the positioning spring 353, the grading filter screen plate 34 can vibrate under the gravity of the glass fragments, thereby providing vibration to the glass fragments received by the grading filter screen plate 34, so that the glass fragments can slide better along the surface of the grading filter screen plate 34, and at the same time, it can ensure that the glass fragments can be filtered better through the grading filter screen plate 34.
[0030] The adjusting component 4 includes a connecting cover 41 that is fixedly connected to the top of the feeding rack 31 and to the upper end of the feeding bin 32. The top of the connecting cover 41 is fixedly connected to the feeding hopper 42, and the feeding hopper 42 is connected to the discharge port 5 through the connecting cover 41 and the feeding bin 32.
[0031] The feeding hopper 32 is equipped with a transmission rod 43, which is movably sleeved in the middle of several grading filter screens 34. The outer surface of the transmission rod 43 is fixedly connected with a linkage pressure ring 44 that fits against the top of the grading filter screen 34.
[0032] The upper end of the transmission rod 43 passes through the feeding bin 32 and extends to the top of the feeding hopper 42, and is fixedly connected to an adjustment knob 45. The external thread of the transmission rod 43 is threaded with a support frame, and the external support frame is fixedly connected to the inside of the feeding hopper 42. Due to the setting of the adjustment component 4, a good feeding effect can be achieved with the cooperation of the connecting cover 41 and the feeding hopper 42. With the cooperation of the linkage pressure ring 44, the height of the grading filter screen plate 34 can be changed through the transmission rod 43, so that the compression degree of the positioning spring 353 can be changed with the cooperation of the positioning frame 351, thereby changing the initial elastic strength of the positioning spring 353, so that it can be used for the impact of glass fragments of different weights, ensuring that the grading filter screen plate 34 has a good vibration effect and can play a good vibration effect on glass fragments of different weights.
[0033] Working principle and usage process of this utility model:
[0034] like Figure 1 The assembly equipment is filled with glass waste through the feeding hopper 42. Under the action of gravity, it falls onto the grading filter screen 34 and is filtered by several grading filter screens 34. The glass fragments of the corresponding size slide along the top of the corresponding grading filter screen 34 into the grading feed inlet 33 and finally flow into the corresponding grinding mechanism in the multi-stage grinding cylinder 1, and then are ground step by step.
[0035] Under the elastic support of the positioning spring 353, the glass fragments falling onto the grading filter screen 34 can impact the grading filter screen 34 and move downwards due to gravity, and then move upwards in the opposite direction under the elastic restoring force of the positioning spring 353. This allows the glass fragments falling onto the grading filter screen 34 to pass through the grading filter screen 34 better, and slide along the surface of the grading filter screen 34 into the grading feed inlet 33, and finally enter the multi-stage grinding cylinder 1.
[0036] The initial rebound strength of the positioning spring 353 is adjusted according to the glass injection volume to ensure that the elastic vibration of the graded filter screen plate 34 corresponds to the weight of the falling glass fragments, thereby ensuring the vibration effect of the glass fragments. This ensures that the graded filter screen plate 34 obtains a good vibration effect under the elastic support of the positioning component 35, thus ensuring that the glass fragments can pass through the graded filter screen plate 34 or slide down along the graded filter screen plate 34 more effectively.
