[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The purpose of this invention is to provide a glass bead cleaning device to solve the problems existing in the prior art and improve the cleaning efficiency of glass beads.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-3 As shown, this embodiment provides a glass bead cleaning device, including a support 1, a drive device 4, an outer barrel 2 and an inner barrel 3 disposed inside the outer barrel 2. The outer barrel 2 is fixedly connected to the support 1, and the drive device 4 is fixedly mounted on the outer barrel 2. The outer barrel 2 is used to drive the inner barrel 3 to rotate relative to the outer barrel 2. The bottom end of the outer barrel 2 is open, and a receiving hopper 11 is fixedly connected to the bottom of the outer barrel 2.

[0024] In this embodiment, the drive device 4 is a motor. The drive device 4 is connected to the inner barrel 3 through a gear transmission mechanism. The output shaft of the motor is fixed with a drive gear 5, and the upper rotating shaft of the inner barrel 3 is fixed with a driven gear 6 that meshes with the drive gear 5.

[0025] The inner barrel 3 has three layers of screens arranged at intervals from top to bottom, and each layer of screen is composed of two sub-screens spliced ​​together. In this embodiment, specifically, the three layers of screens are an upper screen 8, a middle screen 9, and a lower screen 10. The two sub-screens in the upper screen 8 are called upper sub-screens 801, the two sub-screens in the middle screen 9 are called middle sub-screens 901, and the two sub-screens in the lower screen 10 are called lower sub-screens 10. The mesh sizes of the upper screen 8, middle screen 9, and lower screen 10 are different, decreasing sequentially.

[0026] In this embodiment, a scraper is also fixed above each layer of screen. The scraper's function is to use the inertia of the glass beads to disturb the glass beads on the screen when the inner barrel 3 rotates, thereby improving the cleaning effect.

[0027] Each sub-screen is hinged to the inner barrel 3. A pressing and rotating mechanism is provided on the outside of the inner barrel 3 corresponding to each sub-screen. The pressing and rotating mechanism includes a first electric push rod 21 and a first pressure rod 22. One end of the first pressure rod 22 is fixedly connected to the sub-screen, and the first electric push rod 21 is fixedly connected to the inner barrel 3. The first electric push rod 21 is vertically arranged and located above the pressure rod. The free end of the first electric push rod 21 is used to abut against the first pressure rod 22 to drive the sub-screen to rotate relative to the inner barrel 3.

[0028] The top plate of the inner tub 3 is provided with a feeding port, through which glass beads to be cleaned and cleaning water can be added to the inner tub 3. The bottom plate 18 of the inner tub 3 is provided with a discharge port, through which impurities or cleaning water and other materials in the inner tub 3 can be discharged.

[0029] In this embodiment, a pressure sensor is provided at the free end of each first electric push rod 21. The drive device 4, the first electric push rod 21, the second electric push rod 23, and the pressure sensor are electrically connected to the controller. It should be noted that the function of the pressure sensor is to determine the amount of material on the corresponding screen by the force applied to the free end of the first electric push rod 21 by the first pressure rod 22. When the feedback value of the pressure sensor is greater than the set value (which needs to be calculated and tested in advance), it means that the weight of the material on the corresponding screen has reached the set value. At this time, it is necessary to close the screen of the upper layer or stop feeding.

[0030] In this embodiment, the bottom plate 18 of the inner tub 3 is formed by splicing two sub-bottom plates 181. Each sub-bottom plate 181 is hinged to the inner tub 3. A driving mechanism is provided on the outside of the inner tub 3 corresponding to each sub-bottom plate 181. The driving mechanism includes a second electric push rod 23 and a second pressure rod 24. One end of the second pressure rod 24 is fixedly connected to the sub-bottom plate 181. The second electric push rod 23 is fixedly connected to the inner tub 3. The second electric push rod 23 is vertically arranged and located above the second pressure rod 24. The free end of the second electric push rod 23 is used to abut against the second pressure rod 24 to drive the sub-bottom plate 181 to rotate relative to the inner tub 3.

[0031] In this embodiment, a control box 25 is also fixed outside the inner barrel 3. The control box 25 is sealed, and the aforementioned pressing mechanism and drive mechanism are both located in the control box 25.

[0032] In this embodiment, the bottom of the inner tub 3 is provided with a lower rotating shaft 17 and a plurality of first support rods 16. One end of the first support rod 16 is fixedly connected to the inner wall of the inner tub 3, and the other end is fixedly connected to the lower rotating shaft 17. The bottom of the outer tub 2 is provided with a second support rod 20, and a bearing seat 19 is fixedly provided on the second support rod 20. The lower rotating shaft 17 is rotatably engaged with the bearing seat 19 on the second support rod 20 through the bearing. It should be noted that the first support rod 16 is located above the lower bottom plate 18 to avoid affecting the normal opening of the sub-bottom plate 181. The sub-bottom plate 181 is provided with a semi-circular notch corresponding to the lower rotating shaft 17. When the two sub-bottom plates 181 are horizontal, the semi-circular notch fits tightly against the side wall of the lower rotating shaft 17, avoiding interference between the sub-bottom plate 181 and the lower rotating shaft 17.

[0033] In this embodiment, an electric heating rod 7 electrically connected to the controller is also built into the side wall of the outer barrel 2. A blower is also provided in the outer barrel 2. After the glass beads in the inner barrel 3 are cleaned, the air in the outer barrel 2 is heated by turning on the electric heating rod 7 and the blower, and at the same time opening the bottom plate 18 and the feeding port of the inner barrel 3. The hot air is circulated by the blower, thereby drying the glass beads on each screen in the inner barrel 3.

[0034] The glass bead cleaning device in this embodiment also includes a receiving mechanism, which includes a turntable 14, a rotary cylinder 15, a waste hopper 12, and a finished product hopper 13. The waste hopper 12 and the finished product hopper 13 are both mounted on the turntable 14, which is horizontally positioned. The rotary cylinder 15 drives the turntable 14 to rotate around its axis. Both the waste hopper 12 and the finished product hopper 13 can be located directly below the outlet of the receiving hopper 11. The receiving mechanism facilitates the collection of waste glass beads and finished glass beads, reducing the labor intensity of workers.

[0035] The glass bead cleaning device in this embodiment is used as follows:

[0036] First, open the feeding port on the top plate of the inner barrel 3, and close the lower screen 10, bottom plate 18, and discharge port on the bottom plate 18 in the inner barrel 3. Then, put the glass beads to be cleaned into the inner barrel 3. The glass beads entering the inner barrel 3 are initially located on the lower screen 10. Since the first pressure rod 22 on the lower screen 10 abuts against and presses the pressure sensor on the free end of the corresponding first electric push rod 21, the pressure sensor on the free end of the first electric push rod 21 will feed back a pressure signal to the controller. The glass beads on the lower screen 10... When the weight reaches the set value, the signal fed back by the pressure sensor will also be greater than the set value. At this time, the controller controls the middle screen 9 to close, and the glass beads entering the inner barrel 3 will fall on the middle screen 9. Similarly, when the signal fed back by the pressure sensor corresponding to the middle screen 9 is greater than the set value, the controller will control the upper screen 8 to close, and the glass beads entering the inner barrel 3 will fall on the upper screen 8. Similarly, when the signal fed back by the pressure sensor corresponding to the upper screen 8 is greater than the set value, the controller will issue an alarm signal and then stop adding glass beads to the inner barrel 3.

[0037] Then, the inner barrel 3 is driven to rotate by the drive device 4, which throws off the soluble impurities on the surface of the glass beads. At the same time, the glass beads whose particle size does not meet the requirements are screened out by each layer of screens. The thrown-off soluble impurities and glass beads whose particle size does not meet the requirements fall onto the bottom plate 18 of the inner barrel 3. After rotating for a set time period, the drive device 4 is turned off. Then, the rotary cylinder 15 drives the turntable 14 to rotate, so that the waste hopper 12 is located directly below the outlet of the receiving hopper 11. Then, the second electric push rod 23 is retracted, so that the bottom plate 18 of the inner barrel 3 is opened, and the thrown-off soluble impurities and glass beads whose particle size does not meet the requirements will fall into the waste hopper 12.

[0038] Then, the second electric push rod 23 is extended to close the bottom plate 18 of the inner barrel 3, and cleaning water is added to the inner barrel 3 through the feeding port. Then, the inner barrel 3 is driven to rotate by the drive device 4, so that the glass beads and the cleaning water collide with each other to complete the cleaning of the glass beads. At the same time, glass beads that do not meet the size requirements are screened out by each layer of screens. Glass beads that do not meet the size requirements fall on the bottom plate 18 of the inner barrel 3. After rotating for a set time period, the drive device 4 is turned off. Then, the sewage discharge pipe is connected directly below the outlet of the receiving hopper 11, and then the second electric push rod 23 is retracted to open the bottom plate 18 of the inner barrel 3, so that the cleaning water is discharged through the sewage discharge pipe.

[0039] Then, keep the bottom plate 18 of the inner barrel 3 open, open the feeding port of the inner barrel 3, turn on the electric heating rod 7 and the blower to heat the air in the outer barrel 2, and make the hot air flow through the blower to dry the glass beads on each screen in the inner barrel 3.

[0040] Finally, the rotary cylinder 15 drives the turntable 14 to rotate, so that the finished product hopper 13 is located directly below the outlet of the receiving hopper 11. Then, each of the first electric push rods 21 is retracted, so that each layer of screen opens. The cleaned glass beads will fall into the finished product hopper 13, thus completing the cleaning of the glass beads.
