Description

Technical Field

[0001] This utility model relates to hot washing equipment in a waste plastic recycling production line, and more particularly to a horizontal hot washing pot. Background Technology

[0002] In waste plastic recycling production lines, waste plastics such as bottles and shells undergo multiple processes including sorting, crushing, washing, dehydration, air separation, and bagging. Among these processes, washing is a crucial step, and its effectiveness significantly impacts the quality of the plastics produced.

[0003] The cleaning process is divided into pre-cleaning and hot washing. First, the crushed waste plastic is pre-cleaned to remove impurities such as dust, dirt, and sand from its surface. Then, the waste plastic is hot-washed by adding an appropriate amount of hot water and detergent. For ease of description, the mixture of hot water and detergent is called the cleaning solution. The cleaning solution is heated to a certain temperature and maintained for a period of time while being stirred to further remove stubborn stains and residues from the surface of the waste plastic.

[0004] Hot washing of waste plastics typically involves using hot washing equipment. Currently, there are two main types of hot washing equipment on the market. One type uses a rotating drum, but this method has poor cleaning efficiency, failing to completely remove stubborn stains and residues from the surface of the waste plastics. Furthermore, impurities easily accumulate inside the drum, making cleaning difficult. The other type uses a rotating agitator, where a rotating shaft with agitator blades is installed inside the hot washing tank. Driven by a speed reducer, the agitation effect is not ideal due to the limited number of agitator blades. Generally, increasing the washing time is relied upon to improve the cleaning effect. Additionally, impurities easily accumulate inside the hot washing tank, making cleaning difficult. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a horizontal hot washing pot with good cleaning effect, low energy consumption and convenient cleaning of impurities inside the hot washing drum.

[0006] For ease of description, the waste plastics requiring hot washing will be collectively referred to as "materials." Addressing the shortcomings of current hot washing equipment on the market, such as unsatisfactory cleaning effects and difficulty in removing adhering substances, this solution employs a horizontally positioned hot washing tank. Inside the tank, a combination of two-stage spiral blades and plow blades, or a two-stage spiral belt and plow blades, ensures thorough contact and agitation of the materials within the tank with the cleaning solution, thereby improving the cleaning effect. Furthermore, the plow blades can scoop up impurities adhering to the inside of the hot washing drum, preventing them from remaining inside.

A discharge valve is installed at the discharge port. A feeding screw conveyor can also be provided at the outlet of the discharge valve to receive the material mixed with the cleaning liquid that falls out of the discharge valve and convey it to the next station through the feeding screw conveyor.

[0011] A slag removal port communicating with the inner cavity of the hot washing cylinder is provided at the bottom left and right ends of the hot washing cylinder, and a slag removal valve is installed at each slag removal port.

[0012] The stirring shaft is supported in the inner cavity of the hot washing cylinder by a bearing housing assembly, and the stirring shaft is driven to rotate forward or in reverse by a drive device.

[0016] In addition to using a spiral blade + plow blade, the first feeding and mixing structure can also use a spiral belt + plow blade. The specific structure is as follows: The first feeding and mixing structure is as follows: A first spiral belt is arranged on the mixing shaft from the center of the mixing shaft to the left along the first spiral trajectory. Several first plow blades are arranged at intervals on the mixing shaft from the center of the mixing shaft to the left along the first spiral trajectory, and the first spiral belt is fixed to the blade handle of each first plow blade.

[0020] Furthermore, the first and second spiral trajectories rotate in opposite directions.

[0021] Furthermore, in the aforementioned horizontal hot washing tank, the stirring shaft is a hollow shaft structure with a central channel. Several air vents communicating with the central channel are spaced apart on the circumferential sidewall of the stirring shaft. One end of the stirring shaft is driven by a drive device, and the other end is equipped with a rotary valve connected to a compressed air pipe, allowing the compressed air pipe to communicate with the central channel. After the material and cleaning liquid inside the hot washing tank are discharged, the feeding direction of the first and second feeding stirring structures moves from the center to the left and right sides, while compressed air is simultaneously introduced for purging.

[0022] Furthermore, in the aforementioned horizontal hot washing pot, at least one vent is provided at the top of the hot washing cylinder that communicates with the inner cavity of the hot washing cylinder.

[0023] A pH sensor is installed on the hot washing drum body to detect the detergent content in the cleaning fluid inside the hot washing drum body.

[0029] The beneficial effects of this invention are as follows: The mixing utilizes a plow blade, which has advantages such as low resistance, large blade area, and the ability to easily scoop up materials. This reduces energy consumption and improves material agitation. Combined with a horizontally positioned hot washing tank, the material is agitated and moves simultaneously from the center to the left and right sides, or from the left and right sides to the center, through a two-stage spiral blade + plow blade combination or a two-stage spiral belt + plow blade combination. This ensures sufficient contact and agitation between the material and the cleaning liquid, thereby improving the cleaning effect without extending the cleaning time, further reducing energy consumption. Furthermore, the combination of the plow blade and compressed air purging allows for easy cleaning of the hot washing tank. Attached Figure Description

[0039] The horizontal hot washing pot described in this embodiment, such as Figure 1 As shown, it includes: a frame 1, a hot washing drum 2 horizontally disposed on the frame 1, and a detergent adding system for adding detergent into the inner cavity of the hot washing drum 2. In this embodiment, the detergent adding system includes a liquid detergent adding system and a powder detergent adding system.

[0040] The liquid detergent dispensing system is as follows: Figure 1 , Figure 3 and Figure 4As shown, a liquid detergent inlet 6 communicating with the inner cavity of the hot washing drum 2 is provided on the hot washing drum 2. A first pipe 3 is provided at the liquid detergent inlet, and a first valve 4 with a first flow meter 5 is installed on the first pipe 3. The liquid detergent is added into the inner cavity of the hot washing drum 2 through the first pipe 3. The liquid detergent is usually stored in a dosing tank, and the liquid detergent in the dosing tank can be drawn out by the first water pump and sent to the first pipe 3.

[0041] The powder detergent addition system is as follows: Figure 1 , Figure 2 and Figure 4 As shown, a powder detergent inlet communicating with the inner cavity of the hot washing cylinder 2 is provided on the hot washing cylinder 2. A screw conveyor 7 is provided at the powder detergent inlet. The screw conveyor 7 is a common conveying device. This solution uses the screw conveyor 7 to feed the powder detergent, and does not innovate the structure of the screw conveyor 7. Therefore, the structure of the screw conveyor 7 will not be described in detail here.

[0042] In this embodiment, a hot water inlet communicating with the inner cavity of the hot washing cylinder 2 is provided on the hot washing cylinder 2. A hot water pipe is provided at the hot water inlet, and a second valve with a second flow meter is installed on the hot water pipe. Hot water is added into the inner cavity of the hot washing cylinder 2 through the hot water pipe. The hot water can be directly introduced into the hot water pipe from the hot water supply equipment, or a hot water supply tank can be provided to store the hot water. When hot water is needed, the hot water in the hot water supply tank is extracted by the second water pump and sent to the hot water pipe.

[0043] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a feeding port 8 is provided at the top center of the hot washing cylinder 2, which communicates with the inner cavity of the hot washing cylinder 2. A screw conveyor for feeding waste plastic can be installed at the feeding port 8 to achieve automatic feeding.

[0044] In this embodiment, as Figure 2 As shown, a discharge port 9 communicating with the inner cavity of the hot washing cylinder 2 is provided at the center of the bottom of the hot washing cylinder 2. A discharge valve 10 is installed at the discharge port 9. The discharge valve 10 is closed during the hot washing process and the slag removal process, and is only open during the discharge process.

[0045] In this embodiment, as Figure 2As shown, a slag removal port communicating with the inner cavity of the hot washing cylinder 2 is respectively provided at the left and right ends of the bottom of the hot washing cylinder 2. A slag removal valve is installed at each slag removal port. For ease of description, the slag removal port and valve located on the left side are referred to as left slag removal port 11 and left slag removal valve 12, and the slag removal port and valve located on the right side are referred to as right slag removal port 13 and right slag removal valve 14. The left slag removal port 13 and right slag removal port 14 are in a closed state during the hot washing process and the material discharge process, and are only in a closed state during the slag removal process.

[0046] The stirring shaft 15 is supported in the inner cavity of the hot washing cylinder 2 by a bearing seat assembly. In this embodiment, a left bearing support seat 16 is fixedly installed at the left end of the hot washing cylinder 2, and a right bearing support seat 17 is fixedly installed at the right end of the hot washing cylinder 2. The left end of the stirring shaft 15 passes through the left through hole of the hot washing cylinder 2 and is supported in the bearing in the left bearing support seat 16. The right end of the stirring shaft 15 passes through the right through hole of the hot washing cylinder 2 and is supported in the bearing in the right bearing support seat 17. The stirring shaft 15 is driven to rotate forward or backward by a drive device, which is a drive motor 18. The motor shaft of the drive motor 18 is fixedly connected to one end of the stirring shaft 15.

[0047] A first feeding and stirring structure with stirring and feeding functions is provided on the left side of the stirring shaft 15, and a second feeding and stirring structure with stirring and feeding functions is provided on the right side of the stirring shaft 15. When the stirring shaft 15 rotates, the feeding directions of the first feeding and stirring structure and the second feeding and stirring structure are opposite. Therefore, when the stirring shaft 15 is driven to rotate forward or reverse by the driving device, the material in the inner cavity of the hot washing cylinder 2 can move from the left and right sides to the center at the same time or from the center to the left and right sides at the same time through the first feeding and stirring structure and the second feeding and stirring structure.

[0048] The first feeding and stirring structure is as follows: Figure 2 and Figure 5 As shown, a plurality of first spiral blades 19 are arranged at intervals along the first spiral trajectory from the center position of the stirring shaft 15 to the left, and a plurality of first pear blades 20 are arranged at intervals along the first spiral trajectory from the center position of the stirring shaft 15 to the left.

[0049] The second feeding and stirring structure is as follows: a plurality of second spiral blades 21 are arranged at intervals along the second spiral trajectory from the center position of the stirring shaft 15 to the right, and a plurality of second pear blades 22 are arranged at intervals along the second spiral trajectory from the center position of the stirring shaft 15 to the right.

[0050] Each of the first helical blades 19 and each of the second helical blades 21 preferably has a ribbon-like structure.

[0051] In addition to using a spiral blade + plow blade configuration, the first and second feeding and mixing structures can also use a spiral belt + plow blade configuration, as detailed below:

[0052] The first feeding and mixing structure is as follows: a first spiral band is arranged on the mixing shaft 15 from the center position of the mixing shaft 15 to the left along the first spiral trajectory, and a plurality of first plow blades 20 are arranged at intervals on the mixing shaft 15 from the center position of the mixing shaft 15 to the left along the first spiral trajectory, and the first spiral band is fixed on the blade of each first plow blade 20.

[0053] The second feeding and mixing structure is as follows: a second spiral band is provided on the mixing shaft 15 from the center position of the mixing shaft 15 to the right along the second spiral trajectory; a plurality of second pear blades 22 are provided at intervals on the mixing shaft 15 from the center position of the mixing shaft 15 to the right along the second spiral trajectory; and the first spiral band is fixed on the blade bar of each first plow blade 20.

[0054] The first and second helical trajectories rotate in opposite directions, thus ensuring that when the stirring shaft 15 rotates, the conveying directions of the first and second feeding stirring structures are opposite. Assuming that when the stirring shaft 15 rotates clockwise, the first feeding stirring structure conveys material from the center of the inner cavity of the hot washing cylinder 2 to the left, then the second feeding stirring structure conveys material from the center of the inner cavity of the hot washing cylinder 2 to the right. This allows the waste plastic in the inner cavity of the hot washing cylinder 2 to be conveyed to the left and right sides respectively. Conversely, when the stirring shaft 15 rotates counterclockwise, the first feeding stirring structure conveys material from the left side of the inner cavity of the hot washing cylinder 2 to the center, and the second feeding stirring structure conveys material from the right side of the inner cavity of the hot washing cylinder 2 to the center. This allows the waste plastic in the inner cavity of the hot washing cylinder 2 to be collected towards the center.

[0055] During feeding, the stirring shaft 15 rotates so that the conveying direction of the first feeding stirring structure is from the center of the inner cavity of the hot washing cylinder 2 to the left, and the conveying direction of the second feeding stirring structure is from the center of the inner cavity of the hot washing cylinder 2 to the right. Waste plastic enters the middle of the inner cavity of the hot washing cylinder 2 through the feeding port 8, and then is dispersed and tumbled to the left and right sides through the first feeding stirring structure and the second feeding stirring structure.

[0056] During discharge, the direction of rotation of the stirring shaft 15 is opposite to that during feeding, so that the conveying direction of the first feeding stirring structure is from the left side of the inner cavity of the hot washing cylinder 2 to the center, and the conveying direction of the second feeding stirring structure is from the right side of the inner cavity of the hot washing cylinder 2 to the center. The material is turned over and collected towards the center, and the discharge valve 10 is opened, so that the material mixed with the washing liquid is discharged from the discharge valve 10.

[0057] The mixing process utilizes plow blades, which offer advantages such as low resistance, large blade area, and the ability to easily scoop up materials. This reduces energy consumption and enhances material agitation. Combined with a horizontally positioned hot washing pot, the process employs either a two-stage spiral blade + plow blade combination or a two-stage spiral belt + plow blade combination to tumble the material and simultaneously move it from the center to the left and right sides, or vice versa. This ensures thorough contact and agitation between the material and the cleaning liquid, thereby improving the cleaning effect without extending the cleaning time and further reducing energy consumption.

[0058] After the cleaning liquid and materials in the hot washing cylinder 2 are discharged through the discharge valve 10, a small amount of residue will remain inside the hot washing cylinder 2. To prevent the residue from adhering and accumulating, it is necessary to clean the residue inside the hot washing cylinder 2. During cleaning, the rotation direction of the stirring shaft 15 is the same as the rotation direction of the stirring shaft 15 during feeding, so that the conveying direction of the first feeding stirring structure is from the center of the inner cavity of the hot washing cylinder 2 to the left, and the conveying direction of the second feeding stirring structure is from the center of the inner cavity of the hot washing cylinder 2 to the right. The residue is produced by the first plow blade 20 and the second plow blade 22 and pushed to the left cleaning valve 12 and the right cleaning valve 14 respectively. The residue is then cleared out of the hot washing cylinder 2 through the left cleaning valve 12 and the right cleaning valve 14, making the cleaning process very convenient.

[0059] To improve the slag removal effect, a preferred embodiment is to add a purging structure based on the above structure. Specifically, the stirring shaft 15 is a hollow shaft structure with a central channel. Several air-blowing holes 23 communicating with the central channel are spaced apart on the circumferential sidewall of the stirring shaft 15. The air-blowing holes 23 are preferably evenly distributed. One end of the stirring shaft 15 is connected to the drive motor 18, and the other end is equipped with a rotary valve 24, which can be connected to a compressed air pipeline. During the slag removal process of the inner cavity of the hot washing cylinder 2, compressed air is introduced into the compressed air pipeline. The compressed air enters the central channel through the compressed air pipeline and the rotary valve 24, and is then sprayed into the inner cavity of the hot washing cylinder 2 through each air-blowing hole 23, purging the inner cavity of the hot washing cylinder 2 and effectively improving the slag removal effect.

[0060] In this embodiment, as Figure 1 As shown, at least one vent 25 communicating with the inner cavity of the hot washing cylinder is provided at the top of the hot washing cylinder 2. A sealing plate can be provided on the vent 25, and the sealing plate can be removed when ventilation is required.

[0061] In this embodiment, a pH detection sensor is installed on the hot washing drum 2 to detect the detergent content in the cleaning liquid inside the hot washing drum 2. The pH detection sensor can monitor the detergent content in the cleaning liquid inside the hot washing drum 2 in real time to ensure that the amount of detergent added meets the specified requirements.

[0062] In this embodiment, a thermocouple is installed on the hot washing cylinder 2 to detect the temperature of the cleaning fluid inside the hot washing cylinder 2. The temperature of the cleaning fluid inside the hot washing cylinder 2 is monitored in real time by the thermocouple to ensure that the temperature of the cleaning fluid meets the requirements of hot washing.

[0063] In this embodiment, the hot washing cylinder 2 is designed with a hollow jacket structure. A steam inlet and a steam outlet communicating with the hollow jacket are provided on the hot washing cylinder 2. During the hot washing process, steam can be introduced into the hollow jacket for auxiliary heating to ensure the hot washing temperature.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
