Description

Technical Field

[0001] This utility model relates to the technical field of spray granulation and drying equipment, specifically a spray granulation and drying equipment. Background Technology

[0002] Centrifugal spray granulation is the most widely used process in liquid forming, and it is most suitable for producing powdered and granular solid products from solution, emulsion, suspension and paste liquid raw materials. Therefore, when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet precise standards, centrifugal spray granulation is an ideal process. However, some viscous raw materials often adhere to the tower wall, so a mechanism to prevent the spray drying tower from sticking to the wall has emerged.

[0003] A search revealed a Chinese patent document disclosing an anti-sticking centrifugal spray granulation device [Application No.: CN202122542301.9]. This anti-sticking centrifugal spray granulation device includes a centrifugal spray granulation device body, which comprises a granulation device and a drying tower. The granulation device and the drying tower are connected by a conduit. Multiple support pillars are fixedly connected to the drying tower. A movable ring is slidably connected to the inner wall of the drying tower. A cleaning cloth is fixedly connected to the outer wall of the movable ring, and the cleaning cloth contacts the inner wall of the drying tower. Fixed plates are fixedly connected to the upper and lower sides of the inner wall of the drying tower. A screw is rotatably connected between two fixed plates. The screw is threaded onto the left side of the movable ring. A drive assembly for driving the screw to rotate is provided on the screw. A filter screen is fixedly connected to the drying tower, and an anti-clogging component is provided on the filter screen.

[0004] When the device disclosed in the patent is in use, the screw, the first bevel gear and the second bevel gear are all located inside the drying tower. The raw materials inside the drying tower are prone to adhering to the surfaces of the screw, the first bevel gear and the second bevel gear, thereby affecting the normal use of the screw, the first bevel gear and the second bevel gear, which in turn affects the normal use of the moving ring and the cleaning cloth's cleaning effect on the drying tower.

A support 3 is installed on the other side of the drying tower 1, and a drive mechanism 4 is provided on the top of the support 3. A fixing pipe 5 is installed on the surface of the drive mechanism 4. A gas supply pipe 2 is fixedly inserted through the surface of the drying tower 1, and one end of the gas supply pipe 2 is connected to the top of the fixing pipe 5. A device connected to the fixing pipe 5 is embedded in the surface of the drying tower 1. A hollow box 6 is placed inside the drying tower 1. A rotating mechanism 7 is installed inside the hollow box 6. A fixing ring 11 and a storage frame 8 are fixedly connected to the upper and lower parts of the inner wall of the drying tower 1, respectively. A screening screen 9 is embedded inside the storage frame 8 and an auxiliary mechanism 10 is installed. The rotating mechanism 7 and the auxiliary mechanism 10 can generate vibration in cooperation. A vent pipe 12 is embedded inside the fixing ring 11. An exhaust pipe 13 is fixedly connected to the bottom of the vent pipe 12 and passes through the fixing ring 11. An air cylinder 14 is fixedly connected to the bottom of the fixing ring 11. A cleaning mechanism 15 is provided at the bottom of the air cylinder 14. The other end of the air supply pipe 2 passes through the fixing ring 11 and is connected to the vent pipe 12.

[0025] The drive mechanism 4 includes a hydraulic cylinder 41 and an air storage tank 42. The air storage tank 42 is fixedly connected to the top of the bracket 3. The hydraulic cylinder 41 is fixedly connected to the surface of the air storage tank 42. The piston rod of the hydraulic cylinder 41 slides through the air storage tank 42 and is fixedly connected to a piston plate 43. The surface of the piston plate 43 is in contact with the inner wall of the air storage tank 42. One end of the fixed pipe 5 is connected to the air storage tank 42. When the operator starts the hydraulic cylinder 41, the piston plate 43 moves and can compress the gas inside the air storage tank 42. The gas enters the fixed pipe 5 and is injected into the ventilation pipe 12 through the air supply pipe 2. After that, the gas can be injected into the air cylinder 14 through the exhaust pipe 13.

[0026] This equipment is equipped with a control switch that matches the hydraulic cylinder 41. The installation location of the control switch can be selected according to actual usage requirements to facilitate operation and control by the staff.

[0027] The rotating mechanism 7 includes a side plate 71, a rotating shaft 72, a cam 73, and a fan blade 74. The side plate 71 is fixedly connected to the inner wall of the drying tower 1. The rotating shaft 72 rotates through the drying tower 1 and the hollow box 6. One end of the rotating shaft 72 is rotatably connected to the surface of the side plate 71. The fan blade 74 is fixedly connected to the other end of the rotating shaft 72. The cam 73 is fixedly sleeved on the surface of the rotating shaft 72. When the gas flows in the fixed pipe 5, it can assist the fan blade 74 to rotate. When the fan blade 74 rotates, the rotating shaft 72 drives the cam 73 to rotate. When the cam 73 rotates, it can generate vibration in conjunction with the auxiliary mechanism 10 and assist the raw material at the top of the screening screen 9 to fall.

[0028] The auxiliary mechanism 10 includes a connecting frame 101 fixedly connected to the inner wall of the storage frame 8, a spring piece 102 fixedly connected to the top of the connecting frame 101, and a conical block 103 fixed to the top of the spring piece 102. When the cam 73 rotates, it can intermittently squeeze the conical block 103. After that, under the action of the elastic force of the spring piece 102, the conical block 103 returns to its original position. The conical block 103 vibrates by reciprocating up and down. The vibration generated by the auxiliary mechanism 10 acts on the surface of the screening screen 9 in order to accelerate the falling speed of the raw material at the top of the screening screen 9.

[0029] The top of the conical block 103 has a slot, the surface of the cam 73 is in contact with the inner wall of the slot, and the bottom of the inner wall of the slot has an arc design.

[0030] The cleaning mechanism 15 includes a smooth rod 151, a collar 152, a cleaning plate 153, and a lifting plate 154. The smooth rod 151 slides through the bottom of the air cylinder 14. The collar 152 is fixedly sleeved on the surface of the smooth rod 151. The cleaning plate 153 is fixedly connected to the surface of the collar 152. The surface of the collar 152 is in contact with the inner wall of the drying tower 1. The lifting plate 154 is fixedly connected to the top of the smooth rod 151. After gas is injected into the air cylinder 14, the lifting plate 154 is squeezed and can drive the smooth rod 151 to descend. At this time, the collar 152 drives the cleaning plate 153 to descend. After the gas is recovered, the lifting plate 154 can drive the smooth rod 151 to rise, and the cleaning plate 153 rises accordingly. This equipment can scrape off some of the raw materials adhering to the inner wall of the drying tower 1 by the reciprocating movement of the cleaning plate 153.

[0031] Working principle: Raw materials are injected into the drying tower 1 through conduit 17 for drying. During this process, the operator starts hydraulic cylinder 41. The piston rod of hydraulic cylinder 41 drives piston plate 43 to move and compress the air inside air storage tank 42. The gas is injected into the ventilation pipe 12 through fixed pipe 5 and gas delivery pipe 2. When the gas flows inside fixed pipe 5, it can assist the fan blade 74 to rotate. The rotating shaft 72 drives cam 73 to rotate. Cam 73 cooperates with slotted part to drive conical block 103 to descend. Conical block 103 is subjected to the elastic force of spring plate 102. The vibration generated by the auxiliary mechanism 10 is applied to the screening screen 9 by the lifting mechanism, thereby accelerating the fall of the raw material placed on top of the screening screen 9. After the gas is injected into the air pipe 12 through the gas supply pipe 2, it can be discharged into the air cylinder 14 through the exhaust pipe 13. The gas compresses the lifting plate 154, and the smooth rod 151 drives the collar 152 to descend. The cleaning plate 153 descends accordingly and scrapes off the raw material attached to the inside of the drying tower 1. The scraped raw material falls to the top of the screening screen 9 for screening. Finally, the dried raw material can be discharged.
