[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0026] See also Figures 1 to 6 The embodiment of the present invention provides a boiling granulation dryer that is easy to clean. The boiling granulation dryer that is easy to clean includes: a boiling dryer 1, the boiling dryer 1 includes an air intake bin 11, a drying bin 12 and a filter bin 13, the air intake bin 11, the drying bin 12 and the filter bin 13 are connected to each other, filter bags 2 are arranged on both sides of the inside of the filter bin 13, and a cleaning component 3 is provided on the outside of the filter bag 2.

[0027] In the embodiments of the present invention, please refer to Figures 1 to 6 The cleaning assembly 3 includes a support frame 31, which is provided with two support frames 31 and symmetrically mounted on the inner top of the filter chamber 13. The bottom of the support frame 31 is provided with symmetrically distributed electric push rods 311, and the bottom end of the electric push rod 311 is provided with an adapter plate 312. The bottom of the adapter plate 312 is provided with a telescopic rod a313, and the bottom end of the telescopic rod a313 is fixedly connected to the inner bottom of the filter chamber 13. A connecting plate 32 is set between the adapter plates 312 on both sides, and a connecting plate 32 is provided on the connecting plate 32. A rotatably connected linkage ring 33 is provided on the connecting plate 32. A fixedly connected support ring 35 is provided inside the linkage ring 33. The support ring 35 is provided with a plurality of rotatably connected and evenly distributed rotating rods 351 , and a swinging piece 352 fixedly connected is provided on the outer wall of the rotating rod 351; a plurality of annularly distributed linkage teeth 331 are provided inside the linkage ring 33, and a gear 353 meshingly connected therewith is provided on the top of the rotating rod 351. A driving motor 34 is provided on the top of the connecting plate, and a driving wheel 341 is provided at the output end of the driving motor 34, and the outer wall of the driving wheel 341 is against the outer wall of the linkage ring 33. An air intake pipe 321 connected thereto is provided inside the connecting plate 32, and the air intake pipe 321 extends to the outside of the filter bin 13 away from one end of the connecting plate 32, and a plurality of annularly distributed exhaust holes 322 connected thereto are opened on the inner wall of the connecting plate 32.

[0028] It should be noted that: when the electric push rod 311 is retracted, the electric push rod 311 can drive the connecting plate 32 and the swinging piece 352 inside it to slide on the outside of the filter bag 2. During the sliding process, the reciprocating driving motor 34 can drive the driving wheel 341 to rotate synchronously. The rotating driving wheel 341 will drive the linkage ring 33 to reciprocate through the friction force when it abuts against the linkage ring 33. At this time, the linkage tooth 331 inside the linkage ring 33 will drive the corresponding swinging piece 352 to swing back and forth through the engagement with the gear 353. During this process, the swinging piece 352 beats the filter bag 2, which will clean the blocked particles inside the filter bag 2. In this process, air can also be injected into the connecting plate 32 through the air inlet pipe 321. The gas entering the connecting plate 32 will be blown to the filter bag 2 through the exhaust hole 322, thereby achieving secondary cleaning of the filter bag 2.

[0029] In the embodiments of the present invention, please refer to Figures 1 to 6The filter bin 13 is provided with a partition in the center, and both sides of the partition inside the filter bin 13 are provided with a communicating air duct 133, and a valve 134 is provided on the air duct 133. The inner top and inner bottom of the filter bin 13 are both provided with a support seat 132, and both ends of the filter bag 2 are provided with a clamping block 21. The outer wall of the clamping block 21 is against the inner wall of the support seat 132, and the interior of the filter bag 2 is connected with the interior of the air duct 133. Support plates 5 are provided on both sides of the clamping block 21, and a telescopic rod b51 is provided on the outer wall of the support plate 5. The end of the telescopic rod b51 is provided with a fixedly connected limit block 53, and the outer sleeve of the limit block 53 is provided with a slidably connected limit plate 54, and the bottom of the limit plate 54 is fixedly connected to the outer wall of the support seat 132, and the outer sleeve of the telescopic rod b51 is provided with a spring 52, one end of the spring 52 is fixedly connected to the outer wall of the limit block 53, and the other end of the spring 52 is fixedly connected to the outer wall of the support plate 5.

[0030] It should be noted that: through the clamping connection between the limit block 53 and the limit plate 54, when the filter bag 2 is damaged later, the staff can first open the warehouse door 131, and then hold the limit block 53 to make the limit block 53 squeeze the telescopic rod b51. The retracted telescopic rod b51 will drive the limit block 53 to slide out of the limit plate 54, thereby releasing the limit on the filter bag 2, and then the filter bag 2 can be directly taken out of the filter warehouse 13 for disassembly and replacement.

[0031] In the embodiments of the present invention, please refer to Figures 1 to 6 The top of the filter bin 13 is provided with an exhaust pipe 4, which is a three-way pipe. A one-way valve 41 and a flow monitor 42 are provided on the branch pipe in the exhaust pipe 4 that is connected to the filter bin 13, and a bin door 131 is opened at the side wall of the filter bin 13 opposite to the filter bag 2.

[0032] It should be noted that: through the setting of the flow monitor 42, when in use, the flow monitor 42 will detect the exhaust gas flow rate, so as to facilitate the intelligent control of the cleaning component 3 to work.

[0033] The working principle of the easy-to-clean boiling granulation dryer provided by the utility model is as follows:

[0034] When using the device, after the staff adds the raw materials into the boiling dryer 1, the staff can inject air into the boiling dryer 1 through the air inlet bin 11 to perform boiling granulation. The gas generated in this process will be discharged to the outside through the exhaust pipe 4.

[0035] During the discharge process, the flow monitor 42 located on the exhaust pipe 4 will detect the exhaust gas flow rate. When the monitored flow rate value is less than the set value, a signal will be sent to the terminal controller to make the controller close the corresponding valve 134 and open the valve 134 on the other side, thereby allowing the exhaust gas from the boiling dryer 1 to flow into the filter bag 2 on the other side.

[0036] At this time, the controller of the terminal can control the electric push rod 311 in the cleaning component 3 to extend and retract, and the working electric push rod 311 can drive the connecting plate 32 and the swing piece 352 inside it to slide on the outside of the filter bag 2. During the sliding process, the reciprocating driving motor 34 can drive the driving wheel 341 to rotate synchronously, and the rotating driving wheel 341 will drive the linkage ring 33 to reciprocate through the friction force when it hits the linkage ring 33. At this time, the linkage tooth 331 inside the linkage ring 33 will drive the corresponding swing piece 352 to swing back and forth through the engagement with the gear 353. In this process, the swing piece 352 beats the filter bag 2, which will clean the blocked particles inside the filter bag 2.

[0037] During this process, air can be injected into the interior of the communicating plate 32 through the air inlet pipe 321, and the air entering the communicating plate 32 will be blown toward the filter bag 2 through the exhaust hole 322, thereby achieving secondary cleaning of the filter bag 2.

[0038] When the filter bag 2 is damaged, the staff can first open the compartment door 131, and then hold the limit block 53 to squeeze the telescopic rod b51. The retracted telescopic rod b51 will drive the limit block 53 to slide out of the limit piece 54, thereby releasing the limit on the filter bag 2. Then the filter bag 2 can be directly taken out of the filter compartment 13 for disassembly and replacement.

[0039] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0040] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
