Description

Technical Field

[0001] This utility model relates to the technical field of water-absorbing resin drying equipment, specifically, to a circulating drying treatment device for water-absorbing resin. Background Technology

[0002] Drying is a crucial step in the production of absorbent resins. Traditional absorbent resin drying equipment mostly employs static drying, relying solely on heating elements to dry the resin placed in a container. This method has several drawbacks. Firstly, the absorbent resin cannot fully contact the hot air during drying, leading to uneven drying—some resin is over-dried while others are under-dried, affecting product quality. Secondly, static drying is inefficient, has a long drying cycle, and traditional drying equipment lacks an effective recycling mechanism, increasing production costs and energy consumption. Therefore, there is an urgent need for a drying device that can achieve uniform drying of absorbent resins, improve drying efficiency, and has a recycling function. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a circulating drying device for water-absorbing resin. Through the stirring rod and stirring fan blades in the resin circulation component, the water-absorbing resin is made to circulate in the drying cylinder. The stirring fan blades are symmetrically arranged in the center, which can stir the resin in all directions, so that it is constantly turned and moved in the drying cylinder, thereby fully contacting the hot air in the electric heating cylinder and effectively avoiding the problem of uneven drying in some areas.

[0004] A circulating drying device for water-absorbing resin includes a drying cylinder, which is an electric heating cylinder with several heating wires inside. The drying cylinder is fixed on a base, and a cylinder cover is fixed on the base. The lower end of the drying cylinder is a conical funnel shape, and the drying cylinder is fixed inside the cylinder cover. The drying cylinder is connected to a resin circulation assembly, which is used for the resin to circulate within the drying cylinder.

[0005] A solenoid valve is installed at the lower opening of the drying cylinder, and the lower opening of the drying cylinder is fixedly connected to the discharge channel, which is inclined.

[0006] The resin circulation assembly includes a stirring rod with two sets of stirring blades fixed to its arc-shaped surface. The two sets of stirring blades are symmetrically arranged at their centers. The upper end of the stirring rod is rotatably connected to the upper end of the drying cylinder. The stirring rod is disposed inside the drying cylinder. A motor is fixedly disposed on the upper side of the drying cylinder, and the output shaft of the motor is fixedly connected to the stirring rod. A feed inlet is provided at the upper end of the drying cylinder, and a top cover is screwed onto the feed inlet.

[0007] The resin circulation assembly also includes a fan, which is fixed to one side of the air supply chamber. The air supply chamber is fixed to the base and to the lower part of one side of the drying cylinder. The air supply chamber is fixedly connected to the air outlet of the fan and to the drying cylinder. An exhaust port is provided on the upper side of the drying cylinder. A filter element pressure ring is screwed to the exhaust port by several bolts. A filter element placement groove is provided on the lower side of the filter element pressure ring. The diameter of the filter element placement groove is smaller than the diameter of the filter element pressure ring. The lower side of the filter element pressure ring can abut against the upper side of the drying cylinder. After the filter element is placed in the filter element placement groove, it can be pressed down by the filter element pressure ring.

[0008] The filter element has a pore size smaller than the diameter of the resin particles, which facilitates ventilation and blocks the resin.

[0009] The cylinder cover is fixedly equipped with a ladder, and the ladder is fixedly connected from top to bottom to several evenly arranged protective rings.

[0010] The lower part of the base is screwed with screw rods, and the lower end of each screw rod is fixedly connected to a support base.

[0011] The lower sides of the base are each equipped with a rotatable wheel. The wheels have a self-locking function.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are:

[0013] The water-absorbing resin is circulated in the drying cylinder by the stirring rod and stirring fan blades in the resin circulation assembly. The stirring fan blades are symmetrically arranged in the center, which can stir the resin in all directions, making it constantly turn and move in the drying cylinder, so as to fully contact the hot air in the electric heating cylinder and effectively avoid the problem of uneven drying in some areas.

[0014] The motor drives the stirring rod to circulate the resin, accelerating the evaporation of moisture from the resin surface. On the other hand, the fan sends air into the air supply chamber and then into the drying cylinder, forming an airflow that further promotes the discharge of moisture. The combined effect of these two processes greatly shortens the drying time and meets the requirements of large-scale industrial production for drying efficiency.

[0015] The resin circulation assembly enables internal circulation of resin within the drying cylinder, allowing for continuous drying. A cover is installed at the feed inlet at the top of the drying cylinder for easy material addition. The filter element pressure ring and placement slot at the exhaust port facilitate easy filter installation and removal, cleaning, and replacement, ensuring unobstructed ventilation. Furthermore, a ladder and protective ring on the cylinder cover facilitate maintenance and repair by personnel.

[0016] The screw and support base at the bottom of the base can adjust the height of the device to adapt to different work sites; the wheels have a self-locking function, which can fix the device after it is moved into place, ensuring the stability of the device during operation, while also facilitating the movement and handling of the device.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] A circulating drying device for water-absorbing resin includes a drying cylinder 2, which is an electric heating cylinder with several heating wires inside. The drying cylinder 2 is fixed on a base 18, and a cylinder cover 7 is fixed on the base 18. The lower end of the drying cylinder 2 is a conical funnel shape. The drying cylinder 2 is fixed inside the cylinder cover 7. The drying cylinder 2 is connected to a resin circulation assembly, which is used for the resin to circulate within the drying cylinder 2.

[0025] A solenoid valve is provided at the lower opening of the drying cylinder 2, and the lower opening of the drying cylinder 2 is fixedly connected to the discharge channel 16, which is inclined.

[0026] In this embodiment, the drying cylinder 2 is an electric heating cylinder. Several heating wires inside generate heat when energized, which heats the internal space of the drying cylinder 2 to form a high-temperature drying environment, providing a heat source for drying the water-absorbing resin. A solenoid valve is provided at the lower opening of the drying cylinder 2 to realize the opening and closing of the lower opening of the drying cylinder 2, so as to facilitate the control of material discharge.

[0027] The resin circulation assembly includes a stirring rod 15, on which two sets of stirring blades 151 are fixedly mounted. The two sets of stirring blades 151 are symmetrically arranged. The upper end of the stirring rod 15 is rotatably connected to the upper end of the drying cylinder 2. The stirring rod 15 is disposed inside the drying cylinder 2. A motor 1 is fixedly mounted on the upper side of the drying cylinder 2. The output shaft of the motor 1 is fixedly connected to the stirring rod 15. A feed inlet 4 is provided at the upper end of the drying cylinder 2. The feed inlet 4 is screwed to a cover 3.

[0028] In this embodiment, after the motor 1 is started, its output shaft drives the stirring rod 15 to rotate, and the two sets of centrally symmetrical stirring blades 151 fixed on the arc-shaped surface of the stirring rod 15 rotate accordingly. During the rotation, the stirring blades 151 push the water-absorbing resin to circulate in the drying cylinder 2, so that the resin is constantly turned over and moved, realizing the internal circulation of the resin in the drying cylinder 2, and ensuring that the resin is in full contact with the hot air.

[0029] The resin circulation assembly also includes a fan 11, which is fixed to one side of the air supply chamber 12. The air supply chamber 12 is fixed to the base 18 and to the lower part of one side of the drying cylinder 2. The air supply chamber 12 is fixedly connected to the air outlet of the fan 11 and the drying cylinder 2. An exhaust port 201 is provided on the upper side of the drying cylinder 2. A filter element pressure ring 13 is screwed to the exhaust port 201 by several bolts 14. A filter element placement groove 202 is provided on the lower side of the filter element pressure ring 13. The diameter of the filter element placement groove 202 is smaller than the diameter of the filter element pressure ring 13. The lower side of the filter element pressure ring 13 can abut against the upper side of the drying cylinder 2. After the filter element is placed in the filter element placement groove 202, it can be pressed down by the filter element pressure ring 13.

[0030] In this embodiment, the filter element pressure ring 13 and filter element placement groove 202 at the exhaust port 201 are designed to make filter element installation and disassembly convenient, facilitate cleaning and replacement of filter elements, and ensure unobstructed ventilation of the exhaust system. By unscrewing the bolt 14, the filter element pressure ring 13 can be easily removed for easy replacement of the filter element. After replacement, the filter element pressure ring 13 is used to press and fix the filter element.

[0031] After the fan 11 is started, it draws in air from the outside and sends it into the air supply chamber 12 through the air outlet of the fan 11. The air supply chamber 12 then guides the air into the drying cylinder 2. The air flows inside the drying cylinder 2, carrying away the moisture evaporated from the resin surface, and is discharged through the exhaust port 201 on the upper side of the drying cylinder 2.

[0032] The filter element has a pore size smaller than the diameter of the resin particles, facilitating airflow while blocking the resin particles. Because the filter element at the exhaust port 201 has a pore size smaller than the diameter of the resin particles, it can effectively block the resin particles while venting airflow, preventing resin from being discharged with the air.

[0033] A ladder 5 is fixedly installed on the cylindrical cover 7, and several evenly arranged protective rings 6 are fixedly connected to the ladder 5 from top to bottom. The ladder 5 and protective rings 6 on the cylindrical cover 7 facilitate the inspection and maintenance of the device by the staff.

[0034] The lower part of the base 18 is screwed with screw rods 9, and the lower end of each screw rod 9 is fixedly connected to a support base 10.

[0035] The lower sides of the base 18 are respectively equipped with wheels for rotation.

[0036] The working process of this utility model is as follows:

[0037] Depending on the work site conditions, adjust the screw 9 at the bottom of the base 18 to make the support base 10 contact the ground and adjust the device to a horizontal state; if it is necessary to move the device, unlock the self-locking function of the walking wheels, move the device to a suitable position, and then lock the walking wheels.

[0038] Open the top cover 3 of the feed inlet 4 at the top of the drying cylinder 2, and pour the water-absorbing resin to be dried into the drying cylinder 2 through the feed inlet 4. After adding, tighten the top cover 3 to ensure a seal, turn on the power to the heating wire of the drying cylinder 2 to start heating; start the motor 1 to drive the stirring rod 15 and the stirring fan blade 151 to rotate, so that the resin circulates in the drying cylinder 2; at the same time, start the fan 11 to allow air to enter the drying cylinder 2 to form a ventilated environment. After drying is completed, turn off the power, wait for the device to cool down, open the solenoid valve, and discharge the dried resin particles.

[0039] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
