Description

Technical Field

[0001] This utility model relates to the field of flame retardant processing technology, specifically a dryer for flame retardant processing. Background Technology

[0002] A dryer for flame retardant processing is a key piece of equipment specifically designed to remove moisture and solvent residues from flame retardant raw materials or finished products. Its core objective is to ensure that the purity, stability, and performance of flame retardant products meet the standards. For example, the prior art, represented by the prior art document "Dryer for Flame Retardant Processing" (Publication No. CN221444712U), includes a base plate with a support leg installed at the lower corner. A housing is installed at the upper end of the base plate, and a valve is installed at the lower end of the housing. A discharge pipe is installed on the side of the valve. A desiccant stirring mechanism is installed inside the base plate, and a heating plate is installed on the inner wall of the base plate. This invention, by setting up a desiccant stirring mechanism, uses a motor to drive a stirring rod to stir the desiccant, ensuring that the heat generated by the heating plate can fully contact the desiccant, thereby improving the uniformity of heating and enhancing the drying effect. This invention also includes a cover plate fixing mechanism, which facilitates opening and closing of the cover plate for adding the desiccant and prevents heat loss during drying, effectively solving the problems of the prior art. However, its structure still needs improvement, as detailed below: In the existing technology, although the cover can be opened quickly when feeding, the drying chamber is in contact with the outside world for a long time during the feeding process. The high humidity air in the outside environment continuously rushes in, which disrupts the balance inside the drying chamber and causes the relative humidity inside the chamber to rise sharply. In order to counteract the effect of moisture intrusion, the subsequent drying time needs to be extended, which in turn leads to the problem of reduced drying effect and equipment turnover rate. Therefore, a dryer for flame retardant processing is needed to improve the above problems. Utility Model Content

[0003] To address the problem that during prolonged material feeding, the drying chamber is constantly exposed to the outside environment, allowing high-humidity air to continuously enter and disrupting the equilibrium within the chamber, leading to a sudden increase in relative humidity, and necessitating extended drying time to counteract the effects of moisture intrusion, which in turn reduces drying efficiency and equipment turnover, this invention provides a dryer for flame retardant processing to solve the aforementioned issues.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A dryer for processing flame retardants includes a drying chamber body, with feeding components installed between the left and right sides and the top surface of the drying chamber body, stirring components symmetrically arranged in the drying chamber body, and circulation components installed on the side walls of the drying chamber body. The feeding assembly includes electric push rods. Electric push rods are respectively installed on the upper left and right sides of the drying chamber body. Connecting plates are respectively installed on the telescopic ends of the two electric push rods. A feeding box is installed between the two connecting plates on one side close to each other. The feeding box is slidably disposed on the end face of the drying chamber body.

[0005] As a preferred embodiment of this utility model, a through groove is provided on the front side of the feeding box, and an isolation plate is installed on the top surface of the drying box body and on the side near the through groove.

[0006] As a preferred embodiment of this utility model, the bottom surface of the inner cavity of the feeding box is designed with an incline, and the lowest point of the incline of the feeding box is close to the side of the isolation plate.

[0007] As a preferred embodiment of this utility model, the circulation component includes a circulation pipe, and the circulation pipe is installed on the side wall of the drying oven body. The two ends of the circulation pipe pass through the outer wall of the drying oven body and connect to the interior of the drying oven body.

[0008] As a preferred embodiment of this utility model, filter screens are installed at both ends of the inner cavity of the circulation pipe, and a suction fan is installed above the inner cavity of the circulation pipe.

[0009] As a preferred embodiment of this utility model, a discharge pipe is installed on the bottom surface of the drying oven body, and a solenoid valve is installed on the outer wall of the discharge pipe.

[0010] As a preferred embodiment of this utility model, a control panel is installed on the outer wall of the drying oven body.

[0011] As a preferred embodiment of this utility model, the stirring component includes a motor. The motors are symmetrically installed on the outer wall of the drying chamber body. The power output shafts of the two motors pass through the outer wall of the drying chamber body and extend into the interior of the drying chamber body. A connecting shaft is installed on the power output shaft of the motor. The side of the connecting shaft away from the motor is rotatably connected to the inner wall of the drying chamber body. Multiple stirring blades are evenly installed on the outer wall of the connecting shaft.

[0012] Compared with the prior art, this utility model sets up a feeding component in the dryer for flame retardant processing. During the use of the device, the above-mentioned structures cooperate with each other to prevent air interaction between the drying chamber body and the outside world during the feeding process. This feeding method blocks the intrusion of external moisture, maintains a low humidity environment inside the chamber, and eliminates the need for additional time to counteract the effects of moisture, thereby reducing the drying time of a single batch and improving the drying efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example: Please refer to Figure 1 - Figure 4 The dryer for processing flame retardants shown includes a drying chamber body 1, a feeding assembly 3 installed between the left and right sides and the top surface of the drying chamber body 1, a stirring component 6 symmetrically arranged in the drying chamber body 1, and a circulation assembly 2 installed on the side wall of the drying chamber body 1. The feeding assembly 3 includes an electric push rod 301. Electric push rods 301 are installed on the upper left and right sides of the drying chamber body 1. Connecting plates 302 are installed on the telescopic ends of the two electric push rods 301 respectively. A feeding box 304 is installed between the two connecting plates 302 on one side close to each other. The feeding box 304 is slidably disposed on the end face of the drying chamber body 1. A through groove 306 is opened on the front side of the feeding box 304. An isolation plate 305 is installed on the top surface of the drying chamber body 1 and on the side close to the through groove 306. A control panel 4 is installed on the outer wall of the drying chamber body 1. When the feeding box 304 moves upward, the isolation plate 305 will seal the through groove 306. When the through groove 306 is completely removed from the inner cavity of the drying chamber body 1, the upper part of the through groove 306 will move above the isolation plate 305 to facilitate feeding and at the same time prevent air exchange between the inside of the drying chamber body 1 and the outside during feeding.

[0017] In this embodiment, specific references Figure 1 - Figure 3 The bottom surface of the inner cavity of the feeding box 304 is designed with a slope, and the lowest point of the slope of the feeding box 304 is close to the side of the isolation plate 305. The inclined bottom design of the feeding box 304 facilitates the sliding of the flame retardant inside the feeding box 304 into the drying box body 1 when the feeding box 304 enters the drying box body 1.

[0018] In this embodiment, specific references Figure 1 - Figure 3 The circulation component 2 includes a circulation pipe 201. The circulation pipe 201 is installed on the side wall of the drying chamber body 1. Both ends of the circulation pipe 201 pass through the outer wall of the drying chamber body 1 and connect to the interior of the drying chamber body 1. Filter screens 202 are installed at both ends of the inner cavity of the circulation pipe 201. A suction fan 203 is installed above the inner cavity of the circulation pipe 201. During the drying process, the suction fan 203 is activated to draw airflow from the inside of the drying chamber 1 from the top of the circulation pipe 201 and then spray it out from the bottom of the circulation pipe 201, increasing the airflow of the drying chamber 1. The high-speed airflow accelerates heat transfer and further increases the drying efficiency.

[0019] In this embodiment, specific references Figure 1 - Figure 3 The bottom surface of the drying oven body 1 is equipped with a discharge pipe 7, and a solenoid valve 5 is installed on the outer wall of the discharge pipe 7. When material needs to be discharged during the use of the device, the solenoid valve 5 is opened to open the discharge pipe 7, which facilitates the feeding and discharging of the desiccant into the drying chamber body 1.

[0020] In this embodiment, specific references Figure 1 - Figure 3 The stirring component 6 includes a motor 601. Motors 601 are symmetrically installed on the outer wall of the drying chamber body 1. The power output shafts of the two motors 601 pass through the outer wall of the drying chamber body 1 and extend into the interior of the drying chamber body 1. A connecting shaft 602 is installed on the power output shaft of the motor 601. The side of the connecting shaft 602 away from the motor 601 is rotatably connected to the inner wall of the drying chamber body 1. Multiple stirring paddles 603 are evenly installed on the outer wall of the connecting shaft 602. In the process of drying the desiccant, the motor 601 is started, which drives the connecting shaft 602 and the stirring paddle 603 to rotate, thereby stirring and drying the desiccant inside the drying chamber body 1, and further improving the drying efficiency.

[0021] When the dryer for flame retardant processing in this solution needs to be loaded, the two electric push rods 301 are activated to move the connecting plate 302 and the loading box 304 upward. As the loading box 304 moves upward, the upper side of the through groove 306 will be above the top surface of the isolation plate 305. At this time, the inner cavity of the loading box 304 will be connected to the outside, and the loading box 304 will isolate the interaction between the inside and outside of the drying chamber body 1. At this time, the flame retardant is put into the loading box 304 from the through groove 306. Then, the electric push rods 301 are activated again to move the connecting plate 302 and the loading box 304 downward. After the through groove 306 is closed by the isolation plate 305, the inner cavity of the loading box 304 is connected to the inner cavity of the drying chamber body 1. Then, due to the inclined design of the bottom surface of the loading box 304, the flame retardant slides into the inner cavity of the drying chamber body 1. This feeding method prevents external moisture from intruding, maintains a low-humidity environment inside the chamber, eliminates the need for additional time to counteract the effects of moisture, and improves drying efficiency in a single batch. During the drying process, the suction fan 203 is activated to draw airflow from the inside of the drying chamber 1 from the top of the circulation pipe 201 and then spray it out from the bottom of the circulation pipe 201, increasing the airflow of the drying chamber 1. The high-speed airflow accelerates heat transfer and further increases the drying efficiency.
