Description

Technical Field

[0001] The utility model belongs to the field of waste glass recycling equipment, and in particular relates to a screening and cleaning equipment for recycling waste glass. Background Art

[0002] In the process of glass product production and processing, in order to reduce the impact on the environment and recycle resources, a certain proportion of waste glass is generally added to the glass production raw materials to reduce the use of production raw materials. When recycling waste glass, since waste glass contains more impurities, such as dirt, paper scraps, metal fragments, etc., the impurities need to be removed from the waste glass before it can be used for recycling and manufacturing, otherwise it will cause irreversible impact on the quality of the produced glass products. In the existing waste glass cleaning process, due to the different sizes of waste glass, from large fragments of several centimeters in size to glass slag like sand, it is often necessary to clean it in several steps during the cleaning process. Generally, a unified cleaning is performed first to clean out most of the impurities such as mud, sand, and metal, and separate the glass slag from the glass fragments. Since the glass slag is mixed with a small amount of mud, sand, and metal debris, it cannot be used directly and needs to be cleaned a second time. For this reason, the glass slag needs to be transported after the first cleaning and sent to the second cleaning line, which increases the glass cleaning process and prolongs the total cleaning time. For factory production, this cleaning method causes a lot of time and space cost waste, so now there is a need for a device that can complete the cleaning of two types of waste glass, glass fragments and glass slag, in one cleaning process. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a screening and cleaning device for recycling waste glass. By arranging a second cleaning machine under a first cleaning machine, two cleanings can be completed at one time, eliminating the process of separately cleaning glass slag.

[0004] A screening and cleaning device for recycling waste glass includes a frame, a first cleaning machine and a second cleaning machine. The frame serves as the installation framework of the entire device and is used to fix the first cleaning machine and the second cleaning machine. During installation, the first cleaning machine needs to be installed above the second cleaning machine so that impurities and glass residues filtered out by the first cleaning machine can enter the second cleaning machine for cleaning.

[0005] The first cleaning machine includes a drum, a first motor, a sprinkler pipe, a feed hopper, a discharge hopper and a collection hopper. The collection hopper is the main component of the first cleaning machine and is installed on the frame as a whole. The two sides of the drum can be optionally fixed on the side wall of the collection hopper. The opening of the collection hopper can contain the drum as a whole, so that the impurities and glass slag filtered out of the drum during the cleaning process can be collected by the collection hopper. At the same time, multiple water discharge holes are opened on the side wall of the drum, so that the waste water, impurities and glass slag in the drum can enter the collection hopper through the water outlet holes. The first motor is installed on one side of the drum and connected to the drum to provide power for the drum to roll, and then the water outlet end of the sprinkler pipe is extended into the drum to provide a water source for cleaning. The discharge hopper and the feed hopper are installed at the outlet and inlet of the drum respectively. The inlet of the discharge hopper is set below the outlet of the drum, and the outlet of the feed hopper is extended into the inlet of the drum, so that the waste glass can enter the drum through the feed hopper, and after the cleaning is completed, it is collected by the discharge hopper and enters the next process.

[0006] The second cleaning machine includes a cleaning tank, a spiral blade, a second motor and a water spray pipe. The cleaning tank is the main component of the second cleaning. The cleaning tank is installed at an angle below the collecting hopper as a whole. The cleaning tank is a long tank, which is tilted outward as a whole. The lower end is directly below the outlet of the collecting hopper, so that impurities and glass slag can enter the cleaning tank through the outlet of the collecting hopper. A spiral blade is rotatably installed inside the cleaning tank, and one end of the spiral blade is connected to the second motor, so that the second motor can drive the spiral blade to rotate, thereby driving the glass slag to move to a higher place in the cleaning tank. The water spray pipe is installed at the highest point of the cleaning tank, and can continuously spray water into the cleaning tank to provide a water source for the second cleaning.

[0007] In order to improve the cleaning effect, a discharge trough is set at the highest exit of the cleaning tank, and an electromagnet is set in the discharge trough to suck out the metal debris contained in the glass slag. At the same time, in order to facilitate the collection of glass slag, a recovery bin is set under the discharge trough to collect the glass slag in a centralized manner.

[0008] The utility model provides a screening and cleaning device for recycling waste glass, which can clean glass fragments and glass slag at the same time, has good cleaning effect, can effectively remove impurities contained, saves time required for recycling waste glass, and improves work efficiency.

DETAILED DESCRIPTION

[0013] To further illustrate the concept of the present invention, the following will further illustrate the specific implementation of the present invention in conjunction with the accompanying drawings: Embodiment 1

[0014] A screening and cleaning device for recycling waste glass, wherein a frame 1 is welded with steel, four side-standing steel plates are welded on the frame 1 to form a rectangle, and then a funnel is welded with steel plates below to form a collecting hopper 7, and then a steel cylinder side wall with a diameter and length smaller than the opening above the collecting hopper 7 is used to open multiple water discharge holes 8, and then a rotating shaft is welded inside by connecting steel bars, and the two ends of the rotating shaft are fixed on the collecting hopper 7 through bearings to form a drum 2, and a first motor 3 is fixed on the frame 1, and the output end of the first motor 3 is connected to the rotating shaft of the drum 2, and then a water pipe connected to an external water source is welded on the frame 1 as a sprinkler pipe 4, and the water outlet of the sprinkler pipe 4 is extended into the cylinder. Finally, a discharge hopper 6 and a feed hopper 5 are respectively welded on the collecting hopper 7 at both ends of the cylinder.

[0015] A cleaning tank 9 with a trapezoidal cross section is welded with three rectangular steel plates below the collecting hopper 7. Figure 2 As shown, a bracket is welded in the cleaning tank 9 to fix the spiral blade 10, and the output end of the second motor 11 is connected to one end of the spiral blade 10, the second motor 11 and the cleaning tank 9 are welded and fixed on the frame 1, the cleaning tank 9 gradually tilts upward from the bottom of the collecting hopper 7 to the outside, and a water pipe connected to an external water source is arranged on the frame 1 as a water spray pipe 12, so that the water outlet end of the water spray pipe 12 is located at the higher end of the cleaning tank 9. Embodiment 2

[0016] Based on the first embodiment, Figure 1 As shown, a discharge trough 13 is welded on the highest port of the cleaning tank 9, three electromagnets 14 are fixedly arranged side by side inside the discharge trough 13, and then a recovery bin 15 with openings on the top and one side is welded with four steel plates, and the recovery bin 15 is installed below the discharge trough 13.

[0017] The present invention is further described below in conjunction with Example 2. When cleaning waste glass, a conveyor belt is used to transport the waste glass to a feed hopper 5, and the waste glass enters the drum 2 from the feed hopper 5. The drum 2 is continuously rotated by the first motor 3, and at the same time, a watering pipe 4 sprinkles water into the drum 2. The waste glass continuously rolls in the drum 2, and impurities such as soil and glass slag inside are cleaned out. Then, the impurities flow out from the water outlet 8 together with the waste water, and are collected by the collecting hopper 7. The cleaned large pieces of glass fall from the outlet of the drum 2 into the discharge hopper 6 to enter the next process. The impurities collected by the collecting hopper 7 fall into the cleaning tank 9, and the spiral blade 10 continuously stirs under the operation of the second motor 11, and transmits the glass slag and other impurities upward. The water spray pipe 12 located at the high point of the cleaning tank 9 continuously discharges water, and the water flows downward along the cleaning tank 9. In this process, the water flow continuously flushes the impurities inside the glass slag downward, leaving only the heavier glass slag to continue to move upward under the stirring of the spiral blade 10. After passing the highest point of the cleaning tank 9, the glass slag enters the discharge trough 13. In the process of falling in the discharge trough 13, the glass slag continuously passes through the electromagnet 14. Under the action of the high-strength magnetic force of the electromagnet 14, the metal debris contained inside is adsorbed on the electromagnet 14, and finally the glass slag that falls into the recovery bin 15 can be directly used for the next processing step.
