A chemical raw material drying equipment

Abstract

This utility model relates to a chemical raw material drying equipment. First, a drying chamber is operated to heat the inner walls of a first drying chamber and a second drying chamber. Then, raw materials are gradually fed into the first drying chamber through a first inlet, allowing them to fall freely to the bottom. During this free fall, a hot air blower near the first drying chamber operates, generating hot air that heats and dries the raw materials as they fall. The materials then fall into the first drying chamber and are reheated and dried by the inner wall. To further dry the raw materials, a lifting and conveying mechanism is operated to lift the materials from the bottom of the first drying chamber to the top of the second drying chamber, where they are gradually discharged. Simultaneously, a hot air blower in the second drying chamber operates to further dry the materials. The materials then fall into the second drying chamber for further drying.

[0023] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to Figures 1 to 3 As shown, a chemical raw material drying device of this utility model includes a drying box 5, two sets of hot air blowers 6 and a lifting and conveying mechanism. A first drying chamber 16 is provided on one side of the drying box 5, and a second drying chamber 12 is provided on the other side of the drying box 5. The first drying chamber 16 is connected to the second drying chamber 12 through the lifting and conveying mechanism. An air inlet is provided at the upper part of both the first drying chamber 16 and the second drying chamber 12. A hot air blower 6 is connected to one of the air inlets. A first feed inlet 4 is provided at the top of the first drying chamber 16.

[0025] The working principle of this utility model is as follows: In actual production and use, when it is necessary to dry granular chemical raw materials, the drying box 5 can be operated first to heat the inner walls of the first drying chamber 16 and the second drying chamber 12. Then, the raw materials are gradually fed into the first drying chamber 16 through the first feed port 4, allowing the raw materials to fall freely to the bottom of the first drying chamber 16. During the free fall, the hot air fan 6 near the first drying chamber 16 is operated, and the hot air generated by the hot air fan 6 heats and dries the raw materials during the free fall through the air inlet. Then, the raw materials fall into the first drying chamber 16 and are reheated and dried by the inner wall of the first drying chamber 16. In order to better dry the raw materials, the lifting and conveying mechanism can be operated to lift the raw materials at the bottom of the first drying chamber 16 to the upper part of the second drying chamber 12, and then gradually discharge them into the second drying chamber 12. At the same time, the hot air fan 6 at the second drying chamber 12 is operated to dry the raw materials again. Then, the raw materials fall into the second drying chamber 12 and are dried again by the heat generated by the inner wall of the second drying chamber 12.

[0026] Furthermore, the lifting and conveying mechanism includes a conveying pipe 19, a spiral conveying rod 14, and a rotation drive component 18. The conveying pipe 19 is inclinedly arranged in the middle of the drying box 5. The spiral conveying rod 14 is rotatably connected to the inside of the conveying pipe 19. The rotation drive component 18 is drivenly connected to the spiral conveying rod 14. The lowest point of the conveying pipe 19 is located inside the first drying chamber 16. A second feed inlet 2 is provided on one side of the conveying pipe 19 inside the first drying chamber 16. The highest point of the conveying pipe 19 is located inside the second drying chamber 12. A first discharge outlet 13 is provided on one side of the conveying pipe 19 inside the second drying chamber 12.

[0027] As can be seen from the above description, when it is necessary to lift and dry the raw materials in the first drying chamber 16 again, the rotating drive component 18 can be operated to drive the screw conveyor 14 to rotate. Then, the raw materials in the first drying chamber 16 enter the conveying pipe 19 through the second feed port 2 and are discharged to the first discharge port 13 through the screw conveyor 14. During the discharge process, the hot air fan 6 at the second drying chamber 12 heats and dries the raw materials.

[0028] Furthermore, it also includes a discharge valve 11, and a second discharge port 10 is provided at the bottom of the second drying chamber 12, and the discharge valve 11 is provided inside the second discharge port 10.

[0029] As can be seen from the above description, it is beneficial to control the opening and closing of the second discharge port 10 through the discharge valve 11, so that the dried raw materials can be discharged better through the second discharge port 10.

[0030] Furthermore, it also includes a first filter screen 15, which is provided inside each of the air inlets.

[0031] As can be seen from the above description, it is beneficial to filter the air inlet through the first filter screen 15 during the drying process, thereby reducing the impact of raw materials entering the air inlet on the operation of the hot air blower 6.

[0032] Furthermore, it also includes a second filter screen 3. Both the top of the first drying chamber 16 and the second drying chamber 12 are provided with a dehumidification port 1, and the second filter screen 3 is provided inside the dehumidification port 1.

[0033] As can be seen from the above description, it is beneficial for the moisture in the drying oven 5 to be discharged through the vent 1. During the venting process, the vent 1 is filtered by the second filter screen 3 to prevent the raw materials from being blown out of the vent 1.

[0034] Furthermore, it also includes a vibrating feeding assembly. The vibrating feeding assembly is provided on the outside of the drying box 5. The vibrating feeding assembly includes a base 8, elastic elements 7 and a vibrating motor 9. The vibrating motor 9 is detachably connected to the outer surface of the drying box 5. The bottom surface of the drying box 5 is connected to the base 8 through several elastic elements 7.

[0035] As can be seen from the above description, when it is necessary to discharge the raw materials in the first drying chamber 16 into the conveying pipe 19, the vibration motor 9 can be operated to drive the drying box 5 to vibrate, so that the raw materials can slide into the conveying pipe 19 for better conveying, and the dried raw materials can be discharged through the second discharge port 10 better.

[0036] Furthermore, the first drying chamber 16 is provided with a feeding trough 17, which is connected to the second feed inlet 2.

[0037] As can be seen from the above description, it is beneficial to better introduce the raw materials in the first drying chamber 16 into the conveying pipe 19 for transportation.

[0038] Furthermore, it also includes a PLC controller, which is electrically connected to the drying chamber 5, the two sets of hot air blowers 6, and the lifting and conveying mechanism.

[0039] As can be seen from the above description, it is beneficial to adjust the parameters of the chemical raw material drying equipment through the PLC controller, and it makes it more convenient for operators to operate the chemical raw material drying equipment. Example 1
