Description

Technical Field

[0001] This utility model relates to the technical field of waste collection equipment, specifically to a leak-proof waste collection device. Background Technology

[0002] Waste collection equipment refers to machinery or systems used to recycle and process waste materials (such as pearl cotton, plastics, and metals) generated during the production process. Its aim is to reduce resource waste, improve recycling efficiency, and reduce environmental pollution. Pearl cotton is a new type of environmentally friendly foam material with high-strength cushioning and shock resistance. It is flexible, lightweight, and commonly used for the outer packaging of electronic appliances, instruments, computers, audio equipment, and medical devices.

[0003] Chinese utility model patent with announcement number CN222406711U discloses a device for crushing waste pearl cotton, which includes "a primary crushing device that can crush the material initially, and after crushing, the material can enter the inner side of the crushing pot through a fixed groove"; however, the primary crushing box of this device is designed with an opening, and because pearl cotton is lightweight and easily dispersed, leakage often occurs during the primary crushing. Utility Model Content

[0004] The purpose of this invention is to provide a leak-proof waste collection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof waste collection device, including a negative pressure suction machine, characterized in that: one end of the negative pressure suction machine is movably connected to a hopper feeder via a flange, a crushing component is movably connected below the hopper feeder, an antistatic component is provided below the crushing component, and a screening component is provided below the antistatic component.

[0006] The connection points of the hopper feeder, crushing assembly, static eliminator assembly and screening assembly are equipped with sealing rings, and the vertical center lines of the hopper feeder, crushing assembly, static eliminator assembly and screening assembly are aligned.

[0007] The static elimination component includes a static elimination chamber, and ion air bars are movably connected to the inner walls on both sides of the static elimination chamber. There are several ion air bars, and the multiple ion air bars are equidistantly and alternately distributed about the vertical center line of the static elimination chamber.

[0008] The beneficial effects of this utility model are as follows: by combining the hopper-shaped feeder and the negative pressure suction machine, the waste pearl cotton can be sucked into the collection equipment. The internal negative pressure can reduce the possibility of the waste pearl cotton scattering outward. The bottom size of the hopper-shaped feeder is larger than the top size, which can prevent the waste pearl cotton from clogging the feeding part. The ion air bar can remove static electricity from the crushed waste pearl cotton, which can prevent the accumulation of waste pearl cotton, improve the screening effect, and avoid leakage caused by clogging.

[0009] To achieve efficient feeding of EPE foam waste without clogging:

[0010] The further configuration is as follows: the hopper feeder has a hollow hopper structure, and the bottom dimension of the hopper feeder is consistent with the top dimension of the crushing component.

[0011] By adopting the above technical solution, the waste pearl cotton can be quickly fed into the crushing assembly for processing.

[0012] To achieve the processing and reuse of waste pearl cotton:

[0013] The material crushing assembly is further configured such that: a motor is included, and a first gear is rotatably connected to one end of the motor's output shaft; a second gear is meshed with the outer wall of the first gear; both the first gear and the second gear are located on the outside of the crushing chamber; a transmission roller is rotatably connected to one end of the motor's output shaft through the outside of the crushing chamber to the inside; there are multiple transmission rollers; the multiple transmission rollers are symmetrically distributed about the horizontal center line of the crushing chamber; a second gear is rotatably connected to one end of one of the transmission rollers; crushing teeth are movably connected to the outer walls of the multiple transmission rollers; and the crushing teeth of the multiple transmission rollers are alternately distributed.

[0014] By adopting the above technical solution, primary crushing of EPE foam waste can be achieved, making it easier for subsequent screening, compression and granulation processes to be efficiently processed.

[0015] To achieve graded screening of EPE foam waste:

[0016] The further configuration is as follows: the screening assembly includes a screening chamber, and the screening chamber is provided with multiple sorting screens inside. Multiple screening outlets are alternately arranged on both sides of the screening chamber, and the screening outlets are located on one side of the sorting screens. A vibration motor is movably connected to the bottom of the lowest sorting screen, and multiple vibration isolation springs are distributed in a ring around the outside of the vibration motor.

[0017] By adopting the above technical solution, it is possible to perform multi-stage screening and separate collection of pearl cotton waste.

[0018] To achieve more efficient screening of EPE foam waste:

[0019] The further configuration is that the mesh size of the sorting sieve gradually decreases from top to bottom.

[0020] By adopting the above technical solution, waste pearl cotton of different particle sizes can be graded, screened, and collected.

[0021] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] Please see Figures 1 to 5 The leak-proof waste collection equipment includes a negative pressure suction machine 1, one end of which is movably connected to a hopper feeder 2 via a flange, a crushing assembly 3 is movably connected below the hopper feeder 2, an antistatic assembly 4 is provided below the crushing assembly 3, and a screening assembly 5 is provided below the antistatic assembly 4.

[0030] A sealing ring is provided at the connection of the hopper feeder 2, the crushing assembly 3, the static eliminator 4 and the screening assembly 5, and the vertical center lines of the hopper feeder 2, the crushing assembly 3, the static eliminator 4 and the screening assembly 5 are aligned.

[0031] The static elimination component 4 includes a static elimination chamber 401, and ion air bars 402 are movably connected to the inner walls on both sides of the static elimination chamber 401. There are several ion air bars 402, and the multiple ion air bars 402 are equidistantly and alternately distributed about the vertical center line of the static elimination chamber 401.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, the hopper feeder 2 has a hollow hopper structure, and the bottom dimension of the hopper feeder 2 is consistent with the top dimension of the crushing component 3.

[0033] In this embodiment, as Figure 3 As shown, the crushing assembly 3 includes a motor 301, and one end of the output shaft of the motor 301 is rotatably connected to a first gear 302. The outer wall of the first gear 302 is meshed with a second gear 303, and both the first gear 302 and the second gear 303 are located on the outside of the crushing chamber 304. One end of the output shaft of the motor 301 passes through the outside of the crushing chamber 304 to the inside and is rotatably connected to a transmission roller 305. There are multiple transmission rollers 305, which are symmetrically distributed about the horizontal center line of the crushing chamber 304. One end of one of the transmission rollers 305 is rotatably connected to a second gear 303. The outer walls of the multiple transmission rollers 305 are movably connected to crushing teeth 306, and the crushing teeth 306 of the multiple transmission rollers 305 are alternately distributed.

[0034] In this embodiment, as Figure 5 As shown, the screening assembly 5 includes a screening chamber 501, and the screening chamber 501 is provided with multiple sorting screens 502 inside. Multiple screening outlets 503 are alternately arranged on both sides of the screening chamber 501, and the screening outlets 503 are located on one side of the sorting screens 502. The bottom of the lowest sorting screen 502 is movably connected to a vibration motor 504, and multiple vibration isolation springs 505 are distributed in a ring around the outside of the vibration motor 504.

[0035] In this embodiment, as Figure 5 As shown, the mesh size of the sorting sieve 502 gradually decreases from top to bottom.

[0036] The leak-proof waste collection equipment operates as follows:

[0037] First, negative pressure is generated by the negative pressure suction machine 1 (model: ZGXF-5) to form an airflow, which sucks the pearl cotton waste into the crushing chamber 304 through the hopper feeder 2. The motor 301 is started, which drives a transmission roller 305 connected to it and drives the first gear 302 to rotate. The first gear 302 drives the second gear 303 meshing with it to rotate. The second gear 303 drives the transmission roller 305 connected to it to rotate. The two transmission rollers 305 drive the crushing teeth 306 on them to rotate to achieve the purpose of crushing the object. Since the crushing teeth 306 on the two transmission rollers 305 are alternately distributed, the effect of thorough crushing can be achieved.

[0038] The crushed pearl cotton waste falls into the anti-static chamber 401. The alternating ion air bars 402 (model: OL-KP504A-510) on both sides of the anti-static chamber 401 can emit a large number of positive and negative charges, which can neutralize the charge carried by the pearl cotton waste, thereby eliminating the static electricity of the pearl cotton waste. This can prevent the pearl cotton waste from accumulating in subsequent processing steps, which would be detrimental to screening, and can also prevent leakage caused by accumulation.

[0039] After static electricity is removed, the pearl cotton scraps fall into the screening chamber 501. The screen holes of the multi-stage sorting screen 502, which is vertically distributed, gradually decrease in size. Under the action of centrifugal force generated by the rotation of the eccentric block by the vibrating motor 504 (model: YBZD-50-6), the pearl cotton scraps of different sizes move continuously towards the screening outlets 503, which are alternately distributed on both sides. The outlet of the screening outlet 503 is movably connected to other equipment that receives pearl cotton scraps through a flange, ensuring that there is no leakage. The vibration isolation spring 505 reduces the vibration transmitted to the support structure and maintains the stable operation of the vibrating screen.
