Description

Technical Field

[0001] This utility model relates to the technical field of PE pipe recycling devices, and in particular to a PE pipe waste recycling device. Background Technology

[0002] PE pipe, short for polyethylene pipe, is a type of high-molecular polymer pipe, mainly made of polyethylene resin. Depending on its density and application, it can be divided into several types, such as high-density polyethylene (HDPE) pipe, medium-density polyethylene (MDPE) pipe, and low-density polyethylene (LDPE) pipe. HDPE pipe is widely used for water supply and gas transmission due to its pressure resistance and chemical corrosion resistance. MDPE pipe has good flexibility and impact resistance and is often used for sewage and mining water pipelines. LDPE pipe is mainly used for special applications, such as agricultural irrigation and cable protection.

[0003] During the production and use of PE pipes, scrap or waste materials are easily generated. If these waste materials are discarded directly, their non-biodegradable nature can easily damage the ecological environment. However, if they can be melted down and recycled, resources can be recycled, which not only protects the ecological environment but also reduces the production costs of enterprises. However, existing PE pipe waste materials are prone to containing dust and sludge during the recycling process. Direct melting and reuse will result in a large number of impurities in the newly manufactured pipes, affecting product quality. Current cleaning methods generally involve manual rinsing, but PE pipe waste materials vary in size and shape, and this cleaning method incurs high labor costs and low cleaning efficiency, especially for impurities existing in the crevices of the waste materials, where the cleaning effect is poor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a PE pipe waste recycling device, which solves the problems of high labor costs and low efficiency in the existing manual rinsing method, especially the poor cleaning effect for some impurities in the gaps of waste materials.

[0005] According to an embodiment of this utility model, a PE pipe waste recycling device includes a housing, which is fixedly disposed. An inlet and an outlet are fixedly disposed at the top and bottom of the housing, respectively. A bottom cover is sealed and detachably disposed at the outlet. A drain pipe is connected to the bottom of the bottom cover, and a stop valve for controlling its opening and closing is fixedly disposed on the drain pipe. The housing further includes:

[0006] The crushing section is fixedly disposed on the upper part of the housing and communicates with the feed inlet.

The water inlet pipe is turned on to input clean water. Then the second drive source is started to drive the rotating shaft to rotate. The stirring rod on the rotating shaft will stir and clean the small pieces of waste. After cleaning, the dirty water is discharged through the drain pipe. The above operation is repeated until the small pieces of waste are cleaned. Then the bottom cover is opened to discharge the material.

[0009] Furthermore, the first driving source includes a first motor, the output end of the first motor is fixedly connected to the shaft of one of the crushing rollers, a first driving gear is fixedly disposed through the shaft of the crushing roller, and a first driven gear is fixedly connected to the shaft of the other crushing roller, the first driving gear and the first driven gear mesh with each other.

[0010] Furthermore, the housing also includes a fine crushing section, which is connected between the crushing section and the cleaning section. The fine crushing section includes a pair of fine crushing rollers, which are rotatably disposed within the fine crushing section. A second motor for driving the two fine crushing rollers to rotate is fixedly disposed outside the housing.

[0011] Furthermore, the output end of the second motor is fixedly connected to the rotating shaft of one of the fine crushing rollers, and a second drive gear is fixedly disposed through the rotating shaft of the fine crushing roller. A second driven gear is fixedly connected to the rotating shaft of the other fine crushing roller, and the second drive gear and the second driven gear mesh with each other.

Detailed Implementation

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] like Figure 1-6 As shown in the figure, this utility model embodiment proposes a PE pipe waste recycling device, including a housing 1, which is fixedly installed. Several support legs 14 are provided at the bottom of the housing 1 to support the housing 1 and maintain its horizontal stability. An inlet 11 and an outlet 16 are fixedly installed at the top and bottom of the housing 1, respectively. The inlet 11 has a funnel-shaped structure that is wider at the top and narrower at the bottom, facilitating the entry of PE pipe waste. A bottom cover 5 is provided at the outlet 16 in a sealed and detachable manner. The bottom cover 5 can be installed at the outlet 16 by bolts, threads, or other connection methods, and a sealing ring can be arranged around the inside of the bottom cover 5 to ensure the bottom... Regarding the sealing of the cover 5, in this embodiment, a hinge 54 is fixedly connected to one side of the bottom cover 5. The bottom cover 5 is hinged to the side of the discharge port 16 via the hinge 54. The bottom cover 5 can be rotated via the hinge 54 to control its closing or separation from the discharge port 16. A buckle assembly (not shown in the figure) is also provided on the other side of the bottom cover 5 for fixing when the bottom cover 5 and the discharge port 16 are closed. A drain pipe 52 is connected to the bottom of the bottom cover 5. A stop valve 53 that can control its opening and closing is fixedly provided on the drain pipe 52. In this embodiment, the stop valve 53 can be set as a butterfly valve.

[0029] like Figure 2 and Figure 5-6As shown, in this embodiment, the housing 1 further includes a crushing section 2, which is fixedly disposed on the upper part of the housing 1 and communicates with the feed inlet 11. The crushing section 2 includes a pair of crushing rollers 22, which are rotatably disposed within the crushing section 2 and mesh with each other. First limiting teeth 23 are evenly disposed on the two inner sidewalls of the crushing section 2 to fill the gap between the crushing rollers 22 and the inner wall of the crushing section 2, preventing waste from falling and making the crushing rollers 22 rotate more stably. A drive mechanism for the two crushing rollers is fixedly disposed outside the housing 1. The first driving source for rotating the crushing roller 22 includes a first motor 21. The output end of the first motor 21 is fixedly connected to the rotating shaft of the crushing roller 22. A first driving gear 24 is also fixedly disposed through the rotating shaft of the crushing roller 22. A first driven gear 25 is fixedly connected to the rotating shaft of another crushing roller 22. The first driving gear 24 and the first driven gear 25 mesh with each other. A first protective cover 211 is also provided around the outer wall of the crushing part 2 to protect the internal structure.

[0030] like Figure 1-4 As shown, in this embodiment, the housing 1 further includes a cleaning section 4, which is fixedly disposed at the lower part of the housing 1 and communicates with the crushing roller 22 and the discharge port 16 respectively. The cleaning section 4 includes a rotating shaft 44 rotatably disposed therein, and a plurality of stirring rods 45 are evenly disposed on the rotating shaft 44. The stirring rods 45 pass through the rotating shaft 44 and are symmetrically fixed at both ends of the rotating shaft 44. The plurality of stirring rods 45 are equidistantly and crisscrossed along the axial direction of the rotating shaft 44 so that when the rotating shaft 44 rotates, the stirring rods 45 can provide uniform stirring force from all directions. A water inlet pipe 13 is connected to the top of the cleaning section 4, and a device for driving the rotating shaft 44 to rotate is also fixedly disposed outside the housing 1. In this embodiment, the second driving source includes a third motor 41. The end of the motor shaft 411 of the third motor 41 is fixedly connected to a first bevel gear 42, and the top of the rotating shaft 44 is fixedly connected to a second bevel gear 43. The first bevel gear 42 and the second bevel gear 43 mesh with each other, thereby driving the rotating shaft 44 to rotate, so as to stir and clean the small pieces of waste entering the cleaning section 4. After the small pieces of waste are cleaned, they are dried and tested to be qualified, and then they can be used as raw materials for secondary use. As an optional implementation, a hot air mechanism (not shown in the figure) can also be set in the cleaning section 4 of this device. After cleaning, the hot air can be turned on to dry the small pieces of material, thereby further improving the practicality of this device.

[0031] like Figure 2As shown, in this embodiment, a partition 15 is provided between the crushing section 2 and the cleaning section 4. The top of the partition 15 is set as an inclined surface, and a discharge port 121 is provided at the bottom of the inclined surface so that small pieces of waste falling on it can slide from the inclined surface into the discharge port 121. A control valve 12 is also provided at the discharge port 121 to control the opening and closing of the discharge port 121. The control valve 12 is preferably an electric butterfly valve or a pneumatic butterfly valve. The control valve 12 can effectively close the cleaning section 4 to prevent water from overflowing into the crushing section 2 from the discharge port 121 during the cleaning and stirring process.

[0032] like Figure 2 and Figure 4 As shown, in this embodiment, the bottom surface of the cleaning section 4 is set as a plane, and a plurality of scrapers 46 are arranged around the bottom of the rotating shaft 44. The scrapers 46 are separated from the inner wall of the bottom wall of the housing 1. The feed port 11 is located on one side of the rotating shaft 44. When the rotating shaft 44 rotates, the scrapers 46 can push small pieces of waste into the discharge port 16 to prevent small pieces of waste from remaining in the cleaning section 4.

[0033] like Figure 4 As shown, in this embodiment, a filter disc 51 is fixedly installed inside the bottom cover 5. The filter disc 51 is uniformly provided with a plurality of filter holes. The filter holes can filter and collect large particles of PE pipe impurities in the cleaning wastewater, further recycle and reuse resources, and reduce the pressure of waste liquid treatment. After the waste material is discharged, the filter disc 51 is cleaned regularly to increase its service life.

[0034] The technical principle of this utility model is as follows: When in use, PE pipe waste is put into the housing 1 through the feed port 11. The waste will fall into the crushing section 2 first. The first motor 21 is started, and the crushing roller 22 in the crushing section 2 will crush the waste. The small pieces of waste formed will fall into the cleaning section 4. The water inlet pipe 13 is opened to input clean water, and the control valve 12 is closed to seal the discharge port 121. Then the third motor 41 is started to drive the rotating shaft 44 to rotate. The stirring rod 45 on the rotating shaft 44 will stir and clean the small pieces of waste. After cleaning, the dirty water is discharged through the drain pipe 52. The above water inlet operation is repeated until the small pieces of waste are cleaned. Then the bottom cover 5 is opened to discharge the material.

[0035] This invention features a crushing section 2, where the crushing roller 22 can crush PE pipe waste of different sizes and shapes into small pieces of similar size. The smaller pieces of waste have fewer cleaning dead spots, making them easier to clean and recycle. The cleaning section 4 can clean the small pieces of waste that enter it. The rotating shaft 44 drives the stirring rod 45 to rotate, and the water flow and the impact of the stirring rod 45 are used to effectively clean the small pieces of waste. Compared with manual rinsing, the cleaning efficiency is greatly improved, which is beneficial for large-scale application.

[0036] like Figure 2 and Figure 5-6 As shown, according to another embodiment of the present invention, the PE pipe waste recycling device further includes a fine crushing section 3, which is connected between the crushing section 2 and the cleaning section 4. The fine crushing section 3 includes a pair of fine crushing rollers 32, which are rotatably disposed within the fine crushing section 3. The diameter of the fine crushing rollers 32 and the teeth thereon are smaller than those of the crushing rollers 22. Second limiting teeth 33 are also evenly arranged on the two inner sidewalls of the fine crushing section 3 to fill the gap between the fine crushing rollers 32 and the inner wall of the fine crushing section 3, preventing waste from falling and making the fine crushing rollers 32 rotate more stably. A second motor 31 for driving the two crushing rollers 32 to rotate is fixedly installed on the outer side of the housing 1. The transmission method is the same as that of the crushing roller 22. A second drive gear 34 is fixedly connected to the output end of the second motor 31. The second drive gear 34 is fixedly connected to the rotating shaft of one of the crushing rollers 32. A second driven gear 35 is fixedly connected to the rotating shaft of the other crushing roller 32. The second drive gear 34 and the second driven gear 35 mesh with each other. A second protective cover 311 is also provided around the second drive gear 34 and the second driven gear 35 on the outer wall of the crushing part 3 to protect the internal structure.

[0037] Based on the above improvements, the fine crushing roller 32 can perform secondary crushing on small pieces of waste that have been crushed by the crushing roller 22. Since the diameter of the fine crushing roller 32 and the toothed blades on it are smaller than those of the crushing roller 22, it can crush small pieces of waste into smaller, finer, and more uniform pieces, thereby further increasing the cleaning effect on small pieces of material and improving the applicability of the device.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
