Description

Technical Field

[0001] The utility model relates to the technical field of plastic granulation, in particular to a strip material blowing dryer. Background Art

[0002] At present, in the production process of plastic pellets, the plastic strips extruded from the extruder need to pass through a water trough to cool the strips, and then pass through a special pelletizer to cut the plastic strips into pellets. However, after the plastic strips are cooled in the water trough, the surface moisture is heavy and needs to be dried immediately. After the plastic strips are cooled in the water trough, they are passed through a strip dryer to dry the surface moisture before pelletizing.

[0003] The existing technology usually sets a wind box on the top to continue blowing air from top to bottom on the top of the strip material. However, this single-direction drying method is not efficient and requires a large air volume for drying. However, the larger the air volume, the higher the blower power required, which leads to greater energy consumption. Therefore, the utility model proposes a strip material drying machine with higher efficiency and lower energy consumption. Utility Model Content

[0004] The utility model provides a strip material blow dryer, which can effectively solve the above problems.

[0005] The utility model is achieved in this way:

[0006] A strip drying machine comprises a blower, a ventilation pipe connected to the outlet end of the blower, an air distribution box arranged at the upper end of the ventilation pipe and communicating with the ventilation pipe, and a water receiving trough arranged below the air distribution box, wherein a first guide roller and a second guide roller are mounted on the top end of the water receiving trough, and the characteristics are:

[0007] A blowing rod is arranged at the top of the water receiving trough and between the first guide roller and the second guide roller. An air inlet end connected to the ventilation pipe is arranged at one end of the blowing rod. A plurality of annular grooves for guiding the strip materials are formed on the blowing rod. Blowing holes are formed on the sides of the plurality of annular grooves. When air is taken in through the air inlet end, the airflow passes through the inner cavity of the air inlet end and is ejected from the plurality of blowing holes to dry the strip materials.

[0008] As a further improvement, the blowing holes include horizontal blowing holes and vertical blowing holes, and the axes of the horizontal blowing holes and the vertical blowing holes are inclined toward the feeding end of the strip material, so that the horizontal blowing holes and the vertical blowing holes blow air to the bottom and sides of the strip material.

[0009] As a further improvement, the first guide roller and the second guide roller are cylindrical in shape and can both rotate at the water receiving trough. The first guide roller is installed on the side close to the strip material feeding end, and the second guide roller is installed on the side away from the incoming material end.

[0010] As a further improvement, the first guide roller and the second guide roller are both provided with a plurality of annular grooves for guiding the strip material.

[0011] As a further improvement, a first air outlet and a second air outlet are provided at the bottom of the air distribution box, the central axis of the first air outlet is tangent to the side of the first guide roller close to the strip material feeding end, and the central axis of the second air outlet is tangent to the side of the second guide roller away from the strip material feeding end.

[0012] As a further improvement, the water receiving trough is fixed on the outer wall of the ventilation pipe, and a drainage outlet is provided at the lowest point of the bottom of the water receiving trough.

[0013] The beneficial effects of the utility model are:

[0014] 1. Higher drying efficiency and lower energy consumption: The utility model is provided with a blowing rod, which can blow air to the side and bottom of the strip at the same time, overcoming the problem that the existing blow dryer can only blow dry from the top, and improving the drying efficiency. In addition, a number of small blowing holes are provided on the blowing rod, which use a smaller air volume than the blowing holes with large openings on the top air distribution box. When in use, the air volume of a part of the air distribution box can be reduced and redistributed to a part of the air volume used by the blowing rod. The overall air volume is lower than that of the existing blow dryer. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0030] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] Reference Figures 1 to 7As shown, a strip material drying machine includes a blower 1 for providing an air source, a ventilation pipe 2 connected to the outlet of the blower 1, an air distribution box 4 arranged at the upper end of the ventilation pipe 2 and communicating with the ventilation pipe 2, the gas blown by the blower 1 is transmitted to the blowing rod 6 and the air distribution box 4 through the ventilation pipe 2, and a water receiving trough 7 is arranged below the air distribution box 4, the moisture blown off from the strip material 8 is collected by the water trough, and the water receiving trough 7 is fixed on the outer wall of the ventilation pipe 2 without the need for a complicated bracket, and a drainage outlet is provided at the lowest point of the bottom of the water receiving trough 7 for draining water.

[0032] A first guide roller 3, a second guide roller 5 and a blowing rod 6 are mounted on the same horizontal plane at the top of the water receiving trough 7. The blowing rod 6 is arranged between the first guide roller 3 and the second guide roller 5. The air inlet end 61 of the blowing rod 6 is communicated with the ventilation pipe 2. The blowing rod 6 is provided with a plurality of annular grooves for guiding the strip material 8. The sides of the plurality of annular grooves are formed with blowing holes 62. When air is taken in through the air inlet end 61, the air flow passes through the inner cavity of the air inlet end 61 and is ejected from the plurality of blowing holes 62 to dry the strip material. The blowing holes will blow air through the inner cavity of the annular groove. The side and bottom surfaces of the strip material 8 are blown, wherein the blowing holes 62 include horizontal blowing holes and vertical blowing holes, the axes of the horizontal blowing holes and the vertical blowing holes are inclined toward the strip material feeding end, so that the horizontal blowing holes and the vertical blowing holes blow air to the bottom and side surfaces of the strip material. The advantage of this is that the existing blow dryer can basically only blow from the top, and the side and bottom surfaces cannot be blown dry at the same time. When the strip material 8 passes through the blowing rod 6, the moisture on the side and bottom surfaces of the strip material 8 will be blown toward the feeding direction of the strip material 8 by the blowing holes;

[0033] The first guide roller 3 and the second guide roller 5 are cylindrical in shape and can rotate at the water receiving trough 7, which is beneficial to the passage of the strip material 8. The first guide roller 3 is installed on the side close to the feeding end of the strip material 8, and the second guide roller 5 is installed on the side away from the incoming end. The first guide roller 3 and the second guide roller 5 are provided with a plurality of annular grooves for guiding the strip material 8. The annular grooves are used to limit the movement direction of the strip material 8 and can also prevent the strip material 8 from radially deviating under the impact of wind. If a large radial deviation or radial vibration occurs, the strip material 8 will be broken in the radial direction due to the tangential force, affecting production, and the cloth A first air outlet 41 and a second air outlet 42 are provided at the bottom of the bellows 4. The central axis of the first air outlet 41 is tangent to the side of the first guide roller 3 close to the feeding end of the strip material 8, and the central axis of the second air outlet 42 is tangent to the side of the second guide roller 5 away from the feeding end of the strip material 8. This arrangement can remove a large amount of moisture from the strip material 8 when passing through the first guide roller 3 to prevent moisture from being brought to the first guide roller 3. When the strip material 8 leaves the surface of the second guide roller 5, it is regarded as leaving the dryer. When leaving the dryer, the last contact is with the gas to avoid moisture from being brought into contact with the surface of the dryer.

[0034] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
