Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene corrugated pipe production, in particular to a raw material drying device for producing high-density polyethylene corrugated pipes. Background Art

[0002] Polyethylene corrugated pipe, that is, a plastic protective sleeve extruded from polyethylene, has an annular corrugation inside and outside, which protects the cable from damage. It has good wear resistance and corrosion resistance. Because PE material is more corrosion-resistant, wear-resistant and aging-resistant, and green and environmentally friendly, PE corrugated pipes are also often used as rainwater and sewage branch pipes. Existing high-density polyethylene corrugated pipes need to dry the raw materials during production. Traditional drying devices can only dry the raw materials, but cannot grade and screen the raw materials. During drying, the raw materials are piled together, the drying effect is poor, and the drying efficiency is low. In addition, when the existing drying device is drying, a hot air blower is set at the lower end, and hot air is blown into the cavity by the hot air blower, so that hot air can be used for heating while filtering. However, there are some problems during use. During the use of this equipment, because the heating fan is set to heat upward, the hot air blower will affect the filtration of the filter. Statistics show that the effect of hot air drying during filtration is not good, or it has been filtered by the filter before the drying is completely completed, and the degree of drying is uncontrollable. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem solved by the utility model is to provide a raw material drying device for the production of high-density polyethylene corrugated pipes, which solves the problems of uncontrollable drying and filtering and poor drying effect in the prior art.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a raw material drying device for the production of high-density polyethylene corrugated pipes, characterized in that: it includes a box body, an inner cylinder body with a mesh structure is fixedly provided inside the box body, a stirring motor is provided at the upper end of the box body, a stirring device is vertically provided in the cylinder body, and the upper end of the stirring device is drivingly connected to the stirring motor; a feed port and a dehumidification device are provided on one side of the stirring motor, and the dehumidification device is connected to the inner cylinder body; a heating device is provided between the inner cylinder body and the box body; a discharge port is provided at the bottom position of the box body, and a filter box is provided at the lower end of the discharge port, and a first filter screen and a second filter screen are provided in the filter box; a discharge port is provided at the bottom position of the filter box, and brackets are provided on both sides of the discharge port to connect with the filter box; a controller is provided on one side of the box body, and the controller is fixedly connected to the box body.

[0005] The technical principle of this solution is: the inner cylinder is dried by a heating device arranged between the inner cylinder and the box body, so that the mixed material is mixed and dried with high efficiency, and after drying, the unloading door is opened by a driving device to filter the unloading material, which can ensure that the material completely meets the standard after drying before filtering, so that the drying is completely completed at the same time, so that the filtering effect is better, and at the same time, different filter screens are used for filtering and separation, and the remaining material is discharged from the bottom of the filter box after filtering.

[0006] The beneficial effects of this solution are: heating can be performed through the heating device arranged between the box body and the inner cylinder, so that the inside of the inner cylinder arranged with a mesh structure is heated more evenly and the drying effect is better; the vertically arranged stirring device is arranged to stir and dry the raw materials, so that the mixed material in the inner cylinder rotates vertically when stirred by the stirring device, the contact area between the stirring device and the raw materials is large, and the stirring efficiency is higher; after the drying is completed, the material is discharged through the discharge port and then filtered through the first filter screen and the second filter screen to achieve filtration separation, so that the drying state is controllable and the drying effect is good; at the same time, the moisture inside the equipment is sucked through the dehumidification device, so that the raw material drying efficiency is high.

[0007] Furthermore, the first filter screen and the second filter screen are cross-arranged, the mesh size of the first filter screen is larger than the mesh size of the second filter screen, and one end of the first filter screen and the second filter screen are both provided with a filter port. By filtering through the cross-arranged filter screens, hierarchical filtration separation can be better performed, thereby improving filtration efficiency and the accuracy of raw material separation.

[0008] Furthermore, the stirring device is provided with a plurality of inclined through holes, which are arranged vertically. During the stirring process, the mixture can pass through the inclined through holes. The set through holes enable the mixture to be better stirred and dried, thereby improving the turning efficiency of the raw materials during stirring.

[0009] Furthermore, the heating device is arranged between the inner cylinder and the box body in a U-shaped structure, so that the inner box body is heated more evenly and is heated from different directions at the same time, thereby improving the drying efficiency.

[0010] Furthermore, an inclined plate is provided at the bottom of the box body, and the inclined plate is fixedly connected to the box body. The inclined plate allows the dried raw materials to be better gathered on the discharge door through the inclined plate to facilitate subsequent discharge.

[0011] Furthermore, a driving device is provided at the rear end of the box body, and the driving device is connected to the discharge port. The driving device is electrically connected to the controller. The driving device is controlled by the controller to control the opening and closing of the discharge door, which is intelligent and practical.

[0012] Furthermore, brackets are arranged in parallel on both sides of the bottom of the filter box, and the brackets can better support the entire equipment, improve the reliability of the equipment, and support the entire equipment while facilitating unloading at the discharge port.
