[0004] The aforementioned patent relies on springs to support the filter barrel during use. As the vibrator operates, it is prone to tilting due to instability of the center of gravity. Furthermore, since the filter barrel is sealed, the hot and humid air generated during heating cannot be discharged in time, resulting in low drying efficiency and affecting the production efficiency of light calcium carbonate.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A vibratory filtration device for light calcium carbonate includes an outer barrel and an inner material cylinder. The inner material cylinder is suspended inside the outer barrel by at least one set of hanging springs. A filter screen is detachably connected to the upper end of the inner material cylinder. A heating module is fixed to the outer wall of the inner material cylinder. A vibrator is fixed to the center of the bottom of the inner material cylinder. A sealing cover is fixed to the upper end of the outer barrel by a snap fastener. A feed pipe is fixed to the center of the sealing cover. A flexible sealing body is detachably connected between the upper end of the inner material cylinder and the inner wall of the sealing cover. An exhaust pipe is fixed to the sealing cover. An exhaust valve is fixed to the exhaust pipe. A discharge hole is formed on one side of the bottom of the inner material cylinder. A discharge valve is fixed to the lower surface of the inner material cylinder at the position corresponding to the discharge hole.

[0008] Furthermore, the bottom of the inner material cylinder is inclined toward the discharge hole.

[0009] Furthermore, a detection module is fixed on the inner wall above the inner material cylinder of the sealing cap. The detection module includes a temperature sensor, a humidity sensor, and a pressure sensor.

[0010] Furthermore, the flexible connector sealing body is cylindrical, and the length of the flexible connector sealing body exceeds the distance between the sealing cap and the inner material cylinder.

[0013] Furthermore, a discharge pipe is fixed in the discharge hole at the bottom of the outer barrel corresponding to the discharge valve, and a sealing ring is fixed on the inner wall of the upper end of the discharge pipe, which contacts the outer wall of the discharge end of the discharge valve.

[0014] Furthermore, a material dispersing device is detachably connected and fixed to the inner wall of the sealing cover at the position corresponding to the feed pipe.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-5As shown, a vibration filtration device for light calcium carbonate includes an outer barrel 1 and an inner material cylinder 3. The inner material cylinder 3 is suspended inside the outer barrel 1 by two sets of hanging springs 2. A filter screen 8 is detachably connected to the upper end of the inner material cylinder 3. A heating module 6 is fixed on the outer wall of the inner material cylinder 3. The heating module 6 can be any one of electromagnetic heating, water jacket heating, or resistance wire heating. A vibrator 9 is fixed at the center of the bottom of the inner material cylinder 3. A sealing cover 4 is fixed to the upper end of the outer barrel 1 by a snap fastener. A feed pipe 5 is fixed to the center of the sealing cover 4 to facilitate the addition of activated calcium carbonate slurry. A flexible sealing body is detachably connected between the upper end of the inner material cylinder 3 and the inner wall of the sealing cover 4. 14. The flexible sealing body 14 is cylindrical and made of rubber. The length of the flexible sealing body 14 exceeds the distance between the sealing cover 4 and the inner material cylinder 3. One end of the flexible sealing body 14 is fixed to the inner wall of the sealing cover 4, and the other end is installed on the upper end of the inner material cylinder 3 through a detachable connection to achieve a seal and prevent calcium carbonate from entering the outer barrel 1. An exhaust pipe 12 is fixed on the sealing cover 4, and an exhaust valve 11 is fixed on the exhaust pipe 12. The exhaust valve 11 is opened and closed to control the discharge of internal gas. A discharge hole 7 is formed on one side of the bottom of the inner material cylinder 3. A discharge valve 15 is fixed on the lower surface of the inner material cylinder 3 at the position corresponding to the discharge hole 7 to control the discharge of calcium carbonate.

[0028] In this embodiment, the bottom of the inner material cylinder 3 is inclined toward the discharge hole 7, so that the calcium carbonate will automatically move toward the discharge hole 7 and be discharged under the action of vibration when it is discharged.

[0029] In this embodiment, a detection module 10 for detecting internal parameters of the inner material cylinder 3 is fixed on the inner wall above the sealing cap 4. The detection module 10 includes a temperature sensor, a humidity sensor, and a pressure sensor. The temperature sensor is a PT100, the humidity sensor is an HR202, and the pressure sensor is a BRIEM. The drying status of the activated calcium carbonate is determined by detecting the temperature, humidity, and pressure data inside the inner material cylinder 3.

[0030] In this embodiment, the outer barrel 1 is supported on the ground by at least three support mechanisms 19.

[0031] In this embodiment, the lower end of the outer barrel 1 is sealed, and the support mechanism 19 can be fixed on the side wall or the lower end of the outer barrel 1. A support airbag 13 for supporting the inner material cylinder 3 is installed between the lower surface of the inner material cylinder 3 and the inner bottom of the outer barrel 1. The support airbag 13 supports the inner material cylinder 3, which can reduce the force on the hanging spring 2. At the same time, the support airbag 13 can also deform with the vibration of the vibrator 9, which can enhance the vibration stability of the inner material cylinder 3, extend the life of the hanging spring 2, and reduce maintenance costs. A discharge hole is formed at the bottom of the outer barrel 1 corresponding to the position of the discharge valve 15 to facilitate material discharge.

[0032] In this embodiment, a discharge pipe 17 is fixed in the discharge hole at the bottom of the outer barrel 1 corresponding to the discharge valve 15. A sealing ring 18 is fixed on the inner wall of the upper end of the discharge pipe 17, which contacts the outer wall of the discharge end of the discharge valve 15. The sealing ring 18 can be any of the flexible materials such as sponge, rubber, or cotton cloth, and can deform with the shaking of the discharge valve 15 to ensure sealing during discharge.

[0033] In this embodiment, a material dispersing device 16 is detachably connected and fixed to the inner wall of the sealing cover 4 at the position corresponding to the feed pipe 5.

[0034] In this embodiment, the material dispersing device 16 includes a dispersing cone 161, the center of which corresponds to the center of the feed pipe 5. The dispersing cone 161 is installed on the inner wall of the sealing cover 4 by four fixing rods 162. The dispersing cone 161 and the fixing rods 162 are slidably fitted together. A limiting block 163 is installed at the lower end of the fixing rod 162 to limit the height of the dispersing cone 161. The limiting block 163 can be integrally formed with the fixing rod 162 or installed on the fixing rod 162 by threads. The slurry entering from the feed pipe 5 falls on the dispersing cone 161 and disperses, which facilitates the rapid filtration of the slurry.

[0035] In this embodiment, a buffer spring 164 is installed between the distributing cone 161 and the limiting block 163, which is nested on the outer wall of the fixed rod 162. Since the distributing cone 161 and the fixed rod 162 are movably installed, the distributing cone 161 can vibrate up and down under the action of the buffer spring 164 to improve the dispersion effect of the slurry as the slurry enters at different speeds.

[0036] The working principle of this utility model is as follows: When in use, the heating module 6 and the vibrator 9 are started, and then the slurry is injected into the inner material cylinder 3 through the feed pipe 5. The vibrator 9 drives the inner material cylinder 3 to vibrate, thereby filtering impurities. The heating module 6 heats the filtered calcium carbonate in the inner material cylinder 3 by heating the inner material cylinder 3. The detection module 10 automatically monitors the temperature, humidity and pressure in the inner material cylinder 3. When the humidity and pressure exceed the set values, a signal is sent to the control unit. The control unit controls the exhaust valve 11 to open so that the high temperature and humid gas in the inner material cylinder 3 can be quickly discharged from the exhaust pipe 12. When the set temperature and pressure are not reached, the exhaust valve 11 does not open to reduce heat loss, accelerate the rise of the internal temperature of the inner material cylinder 3, and improve the drying efficiency of the activated calcium carbonate. After detecting that the humidity in the inner material cylinder 3 has reached the set value, the discharge valve 15 is opened, and the dried calcium carbonate is discharged from the inner material cylinder 3 through the discharge hole 7.

[0037] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0038] Components not described in detail in this article are existing technologies.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
