[0002] Wet mixing granulator is a commonly used hot melt granulation equipment. During the granulation process, the cylinder needs to be heated and the temperature needs to be kept constant, not too high or too low. Users often use temperature control devices to control the hot melt granulation equipment.

[0003] Existing hot melt granulation devices, especially when producing polymer resins, are prone to clumping of material particles due to differences in the thermoplastic and thermosetting properties of the materials. This can cause the material particles to clumping together due to differences in cooling temperatures during discharge, thus blocking the discharge port and causing poor discharge, thus affecting actual production efficiency.

[0004] In view of this, the utility model provides an effective solution to the problem that the cooling temperature of the existing hot melt granulation device is not easy to control, resulting in easy blockage of materials and low actual production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, Figure 1-Figure 3 The present invention is further described in detail in the following embodiments. The following embodiments are merely examples of implementing the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the scope of the present invention are within the scope of patent protection of the present invention.

[0022] A hot melt granulation device includes a feed plate base 1, an upper opening of the feed plate base 1 is provided with a bin opening 2 and a downwardly connected tube bin, and a material tray 7 is connected to the bottom of the tube bin, and a hopper 9 is provided through the end of the material tray 7 relative to the tube bin, a blanking barrel 5 is fixed to the bottom of the feed plate base 1, a disc bin 12 is obliquely provided in the blanking barrel 5, and the hopper 9 is suspended above the disc bin 12, and a discharge port is provided at the bottom of the oblique surface of the disc bin 12;

[0023] A cooling jacket 8 is provided on the outside of the material tray 7. A plurality of air ducts 16 are arranged in a ring shape on the inner wall between the cooling jacket 8 and the material tray 7. A coolant pump pipe 15 is provided through one end of the cooling jacket 8. The space between the coolant pump pipe 15 and the wall of the cooling jacket 8 is filled with heat-conducting material.

[0024] A substrate frame 4 is fixedly arranged on the outside of the feed plate seat 1;

[0025] In the hot melt granulation device, the falling tube bin structure is connected to the lower material tray 7 through the upper bin port 2, with the bin port 2 serving as the device's discharge interface. The granulator discharge port will enter the tube bin along the bin port 2 and fall into the material tray 7 along the tube bin channel. The material particles are then transported to the disc bin 12 through the bottom hopper 9, and discharged from the bottom discharge port along the slope of the disc bin 12.

[0026] Among them, a cooling jacket 8 is provided outside the material tray 7 connected to the bottom of the pipe bin, and an air duct 16 structure is interconnected between the material tray 7 and the material tray 7. When the cooling jacket 8 is connected to an external air source, the axial airflow enters the material tray 7 along the air duct 16 and mixes with the material tray 7. At the same time, the coolant pump pipe 15 added to the cooling jacket 8 is used to utilize the external coolant source to cooperate with the airflow flowing in the cooling jacket 8 to further improve the cooling effect when the airflow and the material are mixed. At the same time, it is convenient to control the cooling temperature of the node of the material tray 7 according to the control of the coolant source temperature, thereby improving the practicality of the device.

[0027] Compared with the traditional hot melt granulation device, this device uses an external structure to further control the temperature and cool the material particle discharge port, thereby ensuring the smoothness of the material particles during transportation during granulation production and avoiding the blockage of material discharge caused by hot melt adhesion of material particles.

[0028] Furthermore, a turbine coil 3 is fixedly provided on one side of the feed plate seat 1, and an air bin 11 is formed in the turbine coil 3, and the air bin 11 is connected to the cooling sleeve 8. The turbine coil 3 serves as the air source end of the external air source of the cooling sleeve 8, so that the vortex in the air bin 11 can flow into the cooling sleeve 8 and act on the material particles in the feed tray 7 through the air duct 16.

[0029] Furthermore, a convection air duct 6 is fixed in the feed plate base 1, and the convection air duct 6 is suspended above the pipe bin of the feed plate base 1. The convection air duct 6 arranged opposite to it can serve as an auxiliary cooling component, and the downward-blowing pipe structure cooperates with the pipe bin to cool and control the falling material particles, thereby facilitating pre-heat treatment of the material.

[0030] like Figure 2 、 3 As shown, an impeller shaft group 10 is rotatably provided in the material tray 7, and a plurality of curved blades are axially distributed on the impeller shaft group 10. The blades can cooperate with the braking of the impeller shaft group 10 to rotate axially in the material tray 7, thereby breaking up and diverting the materials falling into the material tray 7, avoiding the situation where the temperature difference between the front and rear materials when falling into the material tray 7 affects the actual cooling effect of the material tray 7 and the cooling sleeve 8 due to the temperature difference between the front and rear materials. At the same time, the way of breaking up and diverting the material particles by the blades can further improve the mixing effect and cooling effect of the material particles and the cooling airflow;

[0031] Furthermore, a metal heat-conducting ring is provided between the outer side of the hopper 9 and the coolant pump pipe 15. The expanded metal heat-conducting ring is used to cool the hopper 9, thereby improving the utilization rate of the coolant in the coolant pump pipe 15 and avoiding the influence of the high temperature of the hopper 9 on the discharge of the material particles during the long production process.

[0032] Furthermore, a motor 13 is fixedly installed at the bottom of the disc bin 12, and a sweeping plate 14 is provided in the disc bin 12 to rotate with the motor 13. When the material particles fall into the disc bin 12, the sweeping plate 14 braked by the motor 13 can drive the material particles to slide in a circular direction in the disc bin 12, thereby controlling the diversion of the materials falling front and back, and further ensuring the smoothness of the discharge of the material particles.
