Description

Technical Field

[0001] This utility model relates to the field of waste plastic recycling equipment, and in particular to a PET bottle flake hot washing pot. Background Technology

[0002] Hot washing pots are mainly used for cleaning broken PET bottles. Depending on the customer's surrounding industrial environment, the hot washing machine can be heated electrically or by steam. Cleaning agent powder is added to the water, and a drive motor drives an agitator shaft, causing the bottle flakes and water to rotate simultaneously. The friction between the bottle flakes quickly removes attached impurities and dirt, achieving a hot cleaning of the PET bottle flakes. Existing PET bottle flake hot washing pots have maintained their structure for a long time, but they still have several drawbacks. For example, alkali needs to be added to the water to improve the cleaning effect. In typical hot washing pots, the inlet for adding alkali is the same as the inlet for feeding the bottle, meaning this inlet is relatively large. When alkali is added to the water, the water temperature rises rapidly and boils. The alkali water, under the action of the agitator, splashes out of the unprotected inlet, posing a risk of burns and corrosion to operators. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a PET bottle flake hot washing pot.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A PET bottle flake hot washing pan includes a box with an internal cavity, a drive motor mounted on the box, a feed inlet located on the upper part of the box and connected to the cavity, and a discharge auger located at one end on the bottom of the box and connected to the cavity. The cavity is characterized by being a regular polygonal structure; a feeding structure is provided on the outer side of the box, the feeding structure including a feeding channel fixed to the upper part of the box and connected to the cavity, a rotating shaft rotatably connected to the feeding channel, and a rotating paddle fixed to the rotating shaft and matched to the feeding channel.

[0006] Furthermore, a handle located on one side of the feeding chamber is fixed to one end of the rotating shaft.

[0007] Furthermore, a cover that can be hinged to the upper end of the feeding chamber is provided to cover the feeding chamber.

[0008] Furthermore, the length of the discharge auger entering the bottom of the box is greater than or equal to the distance from the outer side of the box to the center.

[0009] Furthermore, the box has a regular polygonal structure.

[0010] Furthermore, the box and cavity are in the form of a regular octagonal structure.

[0011] Compared with the prior art, this utility model has the following advantages and effects: it has a scientific structure, which can effectively prevent alkaline water from splashing out, reduce possible operational accidents, and improve the cleaning efficiency of PET bottle flakes.

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example

[0020] like Figures 1-2 As shown, this embodiment includes a housing 1, a drive motor 2, a feed inlet 3, and a discharge auger 4 mounted on the housing 1. The housing 1 contains a cavity for holding cleaning water and PET bottle flakes. Inside the cavity are stirring blades 5 connected to the drive motor 2 and capable of rotating within the cavity. The stirring blades 5 are used to stir the cleaning water and PET bottle flakes to improve cleaning efficiency. In this embodiment, both the housing 1 and the cavity are regular octagons. Compared to a traditional cylindrical housing 1, the regular octagonal cavity increases the chance of contact between the inner wall of the cavity and the PET bottle flakes when they rotate, and the repeated collisions also improve the cleaning efficiency of the PET bottle flakes. The feed inlet 3 is located at the top of the housing 1 and connected to the cavity, serving as an inlet for the PET bottle flakes. One end of the discharge auger 4 is located at the bottom of the housing 1 and connected to the cavity, used to discharge the cleaned PET bottle flakes from the bottom of the cavity. In addition, the length of the discharge auger 4 entering the bottom of the box 1 is greater than or equal to the distance from the outer side of the box 1 to the center, which can ensure that all the material enters the discharge auger 4 and is carried out of the box 1.

[0021] like Figures 3-5 As shown, a feeding structure is provided on the outer side of the housing 1. The feeding structure includes a feeding chamber 61 fixed to the upper part of the housing 1 and connected to the cavity, a rotating shaft 62 rotatably connected to the feeding chamber 61, and a rotating paddle 63 fixed to the rotating shaft 62 and matched with the feeding chamber 61. The feeding chamber 61 is used to add alkali. The connection between the feeding chamber 61 and the cavity can be adjusted in size as needed to prevent alkali water from splashing out or to increase the feeding speed of the alkali. The diameter of the rotating paddle 63 is slightly smaller than the width of the feeding chamber 61. Specifically, when the alkali is added into the feeding chamber 61, it will fall onto the rotating paddle 63. The rotation of the rotating paddle 63 will cause the alkali to move and fall into the washing water. The moving rotating paddle 63 can block the alkali water splashed out from the cavity, preventing the operator from being injured.

[0022] In this embodiment, a handle 64 is fixed to one end of the rotating shaft 62, located on one side of the feeding chamber 61. The handle 64 is used to rotate the rotating paddle 63 from outside the feeding chamber 61. In addition, a cover 65 is hinged to the upper end of the feeding chamber 61, which can cover the feeding chamber 61. When feeding is completed or the hot washing pot is not used, the cover 65 is used to seal one end of the feeding chamber 61.

[0023] Compared with existing hot washing pots, the PET bottle flake hot washing pot described in this embodiment has only minor structural changes, but can effectively prevent alkaline water from splashing out, reduce possible operational accidents, and improve the cleaning efficiency of PET bottle flakes.

[0024] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
