In order to further understand the functions of the various components of the present invention, the technical means used, and the expected effects, they will be further described below. I believe that this will provide a more in-depth and specific understanding of the present invention.

As shown in Figure 1, after the overall assembly of the present invention is completed, the spray granulation (top spray) and drying instructions are as follows:

The lifting action of the bottom barrel unit 50 is used to complete the top barrel action, and the barrel unit 40, the drying unit 30 and the filter barrel unit 20 are airtightly connected to prevent the product (powder) from leaking out.

In the production state, the filter bag sets 22 are installed inside the filter barrel body 21. At this time, the piston ring 712 of the cleaning device 70 is located at an upper position of the cylinder 711, and the piston ring 712 drives the spindle. 713 and the spray cleaning head 72, and the spray cleaning head 72 is located in the storage position inside the filter barrel unit 20. The top end 714 of the spindle 713 protrudes from the top wall 211 with a large length. At this time, the The spray head 72 is retracted and moved to the protective cover 74 interior.

Then, as shown by the arrow in FIG. 1 , an exhaust fan (not shown) is used to pump the heated and purified air from the air inlet 511 into the bottom barrel unit 50 so that it can be stored in the barrel unit. The powder inside 40 is in a uniform floating state, and cooperates with the filter bag set 22 in the filter barrel unit 20 to prevent powder leakage. The filter bag set 22 only discharges evaporated water to achieve the purpose of drying. At the same time, the spray unit 60 is used to spray the adhesive or main ingredients, and the spray gun 61 is used to spray the atomized adhesive or main ingredients from the drying unit 30 toward the barrel unit 40, and spray it on the powder in a uniform floating state. The powders are combined into particles and dried by hot air to the required moisture content. During the above-mentioned production process, the spray cleaning head 72 installed inside the filter barrel body 21 is maintained in the storage position, and the spray cleaning head 72 is positioned inside the filter barrel body 21 and is on standby.

During the granulation process without shutting down, the filter bag driving cylinders 23 can be driven to drive the filter bag groups 22 to produce expansion and compression movements, thereby shaking off the dust collected in the filter bag groups 22. The purpose of dust removal of the filter bag groups 22 is achieved. During the dust removal process of the filter bag groups 22 , the spray head 72 retracts and moves to the inside of the protective cover 74 . Therefore, the spray cleaning head 72 will not hook the filter bag groups 22 and prevent the filter bag groups 22 from being damaged.

When the spray granulation (drying) is completed and cleaning operations are to be carried out, first turn off the exhaust fan, stop the exhaust and complete the material collection, and then the filter bag group 22 must be detached from the filter barrel body 21, and then operate the The bottom bucket unit 50 then performs a lifting action to move the material The barrel unit 40 , the drying unit 30 and the filter barrel unit 20 are in airtight connection. At this time, as shown in Figure 3 and with reference to Figure 2 , the driving member 71 is started and the piston ring 712 is directed toward the cylinder 711 The lower position of the piston ring 712 drives the spindle 713 and the spray cleaning head 72 to move downward, and the spray cleaning head 72 is extended to the cleaning position inside the drying unit 30. Then the spray cleaning head 72 receives water. The pressure effect can use the axis L1 as the rotation center to produce a 360-degree rotation relative to the spindle 713. The water outlet cover 722 can also use the center line L2 as the rotation center to produce a 360-degree rotation spray relative to the head body 721 through water pressure. At the same time, , the fixed spray cleaning heads 73 also spray out high-pressure water columns, and the drain valve 512 of the bottom bucket unit 50 will be opened simultaneously to discharge the sewage out of the machine. After the cleaning time is over, the driving member 71 will be started again, and the spray cleaning will The head 72 is slowly retracted, and the high-pressure spray cleaning ball is raised from the drying chamber to the inside of the filter barrel body 21 and positioned for standby (see Figure 1 and Figure 2). After the sewage is drained, the drain valve 512 is closed, and execution can begin. Dryer operation for the next granulation and drying operation.

Therefore, the first embodiment of the drying granulator with a cleaning device of the present invention utilizes the overall configuration and the driving member 71 of the cleaning device 70 to drive the spray cleaning head 72 to the storage position inside the filter barrel unit 20 (See Figure 1), and extend to the cleaning position (See Figure 3) inside the drying unit 30. In the granulation drying production state, the spray cleaning head 72 retracts and moves to the inside of the filter barrel unit 20, And by utilizing the obstruction of the filter bag set 22, the powder will not block the water spray hole of the spray cleaning head 72. When cleaning operation is to be performed, the spray cleaning head 72 is extended to the cleaning position inside the drying unit 30 When set, the spray cleaning head 72 rotates 360 degrees and sprays out high-pressure water columns 360 degrees, which can clean the screen 52, the barrel unit 40, and the drying unit 30. The high-pressure water columns sprayed out by the fixed spray cleaning heads 73 Then the filter barrel body 21 with the filter bag groups 22 removed is cleaned, and the overall cleaning effect is good. Moreover, the mandrel 713 is hollow tubular and extends along the axis L1, and the guide hole 716 is connected from the top end 714 to the bottom end 715 and is connected from the outside of the filter barrel unit 20 to the spray head 72, so that water supply can be simplified. Structure and simplified piping design.

As shown in Figures 6 and 7, a second embodiment of the drying granulator with a cleaning device of the present invention is suitable for coating granular raw materials. It is roughly the same as the first embodiment, and the only difference lies in the The installation position and spray direction of the spray unit 60'.

The spray unit 60' is installed inside the barrel unit 40 and has a plurality of spray guns 61' located at the bottom of the barrel unit 40. The spray guns 61' can spray the adhesive from the barrel unit 40 toward the drying unit 30 Spray.

The description of coating (bottom spraying) is as follows: the hot air flow is introduced from the air inlet 511 of the bottom barrel unit 50, and the granular raw materials are strongly floated from bottom to upward, and the granular raw materials are in a convection state of falling downwards, and the granular raw materials are installed at the bottom. The spray unit 60' sprays upwards on the granular raw materials flowing evenly and floating in the guide tube, so as to achieve the effect of coating and drying the granular raw materials.

The same as the first embodiment, during the coating operation production process, the spray head 72 is retracted and moved to the inside of the filter barrel unit 20 (see Figure 6), and uses the resistance of the filter bag groups 22 to Separated, the powder will not cause obstruction to the water spray hole of the spray cleaning head 72. When the cleaning operation is to be performed (see Figure 7), the spray cleaning head 72 is extended to the cleaning position inside the drying unit 30. The spray cleaning head 72 rotates 360 degrees and sprays out high-pressure water columns 360 degrees, which can clean the screen. The net 52, the barrel unit 40, the drying unit 30, and the filter barrel body 21 with the filter bag groups 22 removed are cleaned, and the cleaning effect is good. Therefore, the second embodiment can also achieve the same objectives and effects as the first embodiment.
