[0048] A discharge port 22 is provided on one side of the drying tank 1;

[0049] The drying tank 1 is provided with a mounting frame 13 inside, on which two cylinders 14 are fixedly mounted, and the output ends of the two cylinders 14 pass through the mounting frame 13, a material stopper 11 is installed at the output end of one of the cylinders 14, and a material guide frame 12 is installed at the output end of the other cylinder 14, a notch is provided on the side frame 3, the material stopper 11 is adapted to the notch, the material guide frame 12 is adapted to the groove, and the material stopper 11 is located at the discharge port 22;

[0050] The inner cavity of the drying tank 1 is provided with an air guide duct 17, and an air delivery duct 18 is provided around the bottom of the air guide duct 17. The air delivery duct 18 is vertically above the groove.

[0051] A hot air blower 19 is installed on the outer wall of the drying tank 1 , and the hot air blower 19 is connected to the air duct 17 through a pipeline.

[0052] The preferred solution of the low-temperature energy-saving drying device for the production of organic bentonite is:

[0053] Heat Pump 20 Energy Saving System

[0054] Working principle:

[0055] The heat pump 20, the core energy-saving component of this device, operates based on a thermodynamic reverse cycle. Its input is connected to the interior of the drying tank 1 via a pipe, absorbing the low-temperature waste heat generated during the drying process and the latent heat released by the condensation of water vapor in the moist air.

[0056] After being compressed and heated by the heat pump 20, the high-temperature hot air is transported to the air guide duct 17 through the output end pipe, and then evenly blown to the organic bentonite on the rotating belt 4 through the air delivery pipe 18, achieving a low-temperature and high-efficiency drying effect.

[0057] This design significantly reduces energy consumption, improves thermal energy utilization, and achieves energy-saving goals.

[0058] Sliding connection between the slide groove and the slide rail 5

[0059] Working principle:

[0060] The sliding grooves on the side walls of the revolving frame 2 and the side frame 3 form a stable sliding connection with the sliding rods on the side walls of the slide rail 5, ensuring the smooth operation of the rotating belt 4 on the revolving frame 2.

[0061] This design enables the rotating belt 4 to smoothly drive the organic bentonite to rotate and turn, thereby improving the drying uniformity and efficiency.

[0062] At the same time, the cooperation between the slide groove and the slide rail 5 also enhances the stability and durability of the device.

[0063] L-shaped mounting bracket 13

[0064] Working principle:

[0065] The L-shaped mounting frame 13 provides a stable mounting base for the cylinder 14 , ensuring that the cylinder 14 can accurately and stably push the material blocking frame 11 and the material guiding frame 12 during the extension and retraction process.

[0066] This structural design is reasonable, easy to install and maintain, and at the same time optimizes the space layout and improves the compactness and working efficiency of the device.

[0067] Installation method of pipe bracket 15 and clamping ring 16

[0068] Working principle:

[0069] The clamping ring 16 provided around the inner side of the pipe frame 15 provides convenience and stability for the installation of the air duct 17. The air duct 17 is fixed to the pipe frame 15 by the clamping ring 16, ensuring the stability and position accuracy of the air duct 17.

[0070] This installation method allows hot air to be blown evenly and efficiently toward the organic bentonite through the air guide pipe 17 and the air delivery pipe 18, thereby improving the drying effect.

[0071] Design of vibration motor 10 and vibration slot 9

[0072] Working principle:

[0073] The vibration motor 10 is installed in the vibration groove 9 of the rotating frame 2, and its output end is in contact with the frame of the groove. When the vibration motor 10 is working, the vibration generated is transmitted to the organic bentonite on the groove and the rotating belt 4, causing the organic bentonite to slide out from the discharge port 22.

[0074] At the same time, during drying, this vibration effect helps to break up the lumps and adhesions between the materials, and promotes the uniform distribution and turning of the materials on the rotating belt 4, thereby further improving the drying uniformity and efficiency.

[0075] Setting of sealing gasket

[0076] Working principle:

[0077] The sealing pad is installed at the joint between the side frame 3 and the inner wall of the drying tank 1, which plays a good sealing effect. It effectively prevents the heat and moisture generated during the drying process from leaking out from the joint.

[0078] This sealing design not only improves the drying efficiency, but also maintains the stability and controllability of the internal environment of the drying tank 1, which is conducive to achieving the goal of low-temperature and energy-saving drying.

[0079] This utility model describes a low-temperature energy-saving drying device for the production of organic bentonite. Its working principle mainly revolves around the following core components and steps:

[0080] Feeding and conveying:

[0081] The raw material organic bentonite enters the device through the feed hopper 21, then falls vertically into the groove between the rotating frame 2 and the side frame 3 through the conveying pipe 24, and is distributed on the rotating belt 4. This step ensures that the raw material can enter the drying area accurately and quickly.

[0082] Rotation, flipping and uniform distribution:

[0083] When drive motor 7, mounted at the center bottom of rotating frame 2, is activated, drive gear 23, fixed to its output end, engages rack 6 at the bottom of the groove, thereby driving rotating belt 4 to rotate smoothly within the groove. As rotating belt 4 rotates, the organic bentonite is evenly stirred, increasing the heated surface and improving drying efficiency.

[0084] Hot air circulation and drying:

[0085] A hot air blower 19 on the outer wall of the drying tank 1 is connected to an air duct 17 within the inner cavity via a pipe. The hot air generated is fed through the air duct 17 and blown vertically toward the organic bentonite above the groove through an air duct 18 surrounding the bottom. The hot air circulates within the device, continuously and evenly drying the material while also utilizing low-temperature energy-saving technology to reduce energy consumption.

[0086] Discharge control:

[0087] Inside the drying tank 1, a mounting frame 13 is installed. Two pneumatic cylinders 14, mounted on this mounting frame, control the movement of the retaining frame 11 and the guiding frame 12, respectively. When drying is complete, the cylinders 14 push the retaining frame 11 and the guiding frame 12 to the appropriate position, allowing the dried organobentonite to be discharged smoothly through the notches in the side frames 3 and the discharge port 22. This step automates the drying process and improves production efficiency.

[0088] Sealing and energy saving:

[0089] The overall design of the device emphasizes sealing, such as the installation of a sealing gasket at the joint between the rotating frame 2 and the inner wall of the drying tank 1, to reduce heat loss and moisture intrusion. Furthermore, the use of a low-temperature, energy-saving hot air blower 19 and a rational hot air circulation system design further reduce energy consumption and improve drying efficiency.

[0090] In summary, the low-temperature energy-saving drying device for organic bentonite production achieves low-temperature, high-efficiency and energy-saving drying of organic bentonite through the synergistic effect of multiple steps and components such as feeding and conveying, rotation and uniform distribution, hot air circulation and drying, discharge control, sealing and energy saving.

[0091] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
