Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, specifically to a drying device for pesticide dry suspensions. Background Technology

[0002] Dry pesticide suspensions belong to the category of "functional granules" in solid formulations. The core of this product is to make pesticide active ingredients and adjuvants into dry granules that can be quickly dispersed in water. It combines the high efficiency of traditional water suspensions with the stability of fixed formulations and is one of the important directions for the upgrading of pesticide formulations. When storing dry pesticide suspensions, it is usually necessary to remove excess water from them and convert the wet material into dry granules that meet quality standards.

[0003] When drying pesticide dry suspensions, spray drying towers are usually used. After drying, a collection box is placed at the discharge port at the bottom of the drying tower, and then the valve at the bottom of the drying tower is opened to release the dried dry suspension inside so that it falls into the collection box below.

[0004] When placing the collection box, staff need to manually place it under the drying tower. After it is full, it is pulled out. Since the discharge port of the drying tower is usually located at the bottom, staff need to bend over to operate the collection box after placing it and pulling the collection box full of dry suspension, which is quite strenuous. Utility Model Content

[0005] To overcome the above-mentioned defects, the present invention provides a drying device for pesticide dry suspension, which solves the technical problem in the prior art that when the collection box is placed in the drying tower or pulled out, it is placed at the bottom of the drying tower, which requires the operator to bend over and move it forward, which is quite troublesome.

[0006] According to one aspect, at least one embodiment of the present invention provides a drying device for a pesticide dry suspension, including a spray drying tower mounted on a support frame, and further including a moving rail, a moving plate, a collection box, a push-pull assembly, a limiting assembly, and a positioning assembly. Two of the moving rails are fixedly mounted on the support frame, the moving plate is slidably mounted on the two moving rails, the collection box is in contact with the top end of the moving plate, the push-pull assembly is disposed on the moving plate for pushing and pulling the collection box, the limiting assembly is disposed on the moving plate for limiting the collection box when it is pushed and pulled, and the positioning assembly is disposed on the support frame for controlling the collection box to move directly below the spray drying tower.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-4 As shown, this invention illustrates a drying device for pesticide dry suspension in one embodiment of the present invention. It includes a spray drying tower 2 mounted on a support frame 1, and further includes a moving rail 3, a moving plate 4, a collection box 5, a push-pull assembly, a limiting assembly, and a positioning assembly. Two moving rails 3 are fixedly mounted on the support frame 1. The moving plate 4 is slidably mounted on the two moving rails 3. The collection box 5 contacts the top of the moving plate 4. The push-pull assembly is mounted on the moving plate 4 for pushing and pulling the collection box 5. The limiting assembly is mounted on the moving plate 4 for limiting the collection box 5 when it is pushed or pulled. The positioning assembly is mounted on the support frame 1 for controlling the collection box 5 to move directly below the spray drying tower 2.

[0024] When drying the dry suspension, the active ingredients and adjuvants of the pesticide are first mixed with water to form a uniform aqueous suspension. A pressure atomizer is used, and the liquid is delivered to the nozzle through a high-pressure diaphragm pump to disperse it into droplets. The internal air is filtered and heated to 180℃-250℃ by the internal steam heater. The hot air forms a rotating airflow through the spiral air distributor at the top of the tower and flows down in parallel with the atomized droplets. After the water evaporates, the fixed components in the liquid condense to form dry particles, which then fall to the bottom of the spray drying tower 2.

[0025] like Figure 2 and Figure 4As shown, after drying, because the top of the moving plate 4 has a groove that matches the bottom of the collection box 5, the collection box 5 is placed in the groove of the moving plate 4. It is then pushed to the discharge port of the spray drying tower 2 by the push-pull assembly and positioning assembly. The push-pull assembly includes a fixed frame 6, a rotating shaft 7, a push-pull handle 8, and a placement assembly. Two fixed frames 6 are fixedly installed on the side of the moving plate 4, and the rotating shaft 7 is rotatably installed on the side of the two fixed frames 6. The push-pull handle 8 is fixedly installed on the rotating shaft 7 and has a pull groove. The placement assembly is set on the support frame 1 and includes a connecting rope 9 and a hook 10. One end of the connecting rope 9 is fixedly installed on the inner top of the support frame 1, and the top of the hook 10 is fixedly installed on... Installed at the other end of the connecting rope 9, the positioning component includes a mounting plate 14 and a positioning post 15. The mounting plate 14 is fixedly installed on the side of the support frame 1, and the positioning post 15 is fixedly installed on the side of the mounting plate 14. Specifically, when the operator pushes the push-pull handle 8, the moving plate 4 moves forward. When the side of the positioning post 15 contacts the side of the collection box 5, the collection box 5 is located directly below the spray drying tower 2. When the side of the collection box 5 contacts the side of the collection box 5, the collection box 5 is located directly below the spray drying tower 2. The push-pull handle 8 can rotate when pushed and pulled, so as to adapt to different push-pull angles of different operators. After placement, the push-pull handle 8 can be rotated to ninety degrees and hooked into the pull groove of the push-pull handle 8 by the hook 10 to hook it for placement.

[0026] like Figure 3 As shown, when the collection box 5 moves back and forth, it can be limited by a limiting component to prevent it from sliding out due to inertia. The limiting component includes a limiting frame 11, a limiting frame 2 12, and a support rod 13. Two limiting frames 11 are fixedly installed on the top of the moving plate 4, and two limiting frames 2 12 are rotatably installed on the sides of the two fixed frames 6. The support rod 13 is fixedly installed on the sides of the fixed frames 6. Specifically, if the collection box 5 has a forward tendency, the limiting frame 11 can block it; if the collection box 5 moves backward (towards the push / pull handle 8), the limiting frame 12 can stop it. When the movement is in progress, the second limiting frame 12 can block it. At this time, the second limiting frame 12 can be rotated to a horizontal position. Because the top of the support rod 13 has a placement groove that matches the bottom of the second limiting frame 12, the second limiting frame 12 can be rotated into the placement groove of the support rod 13. When placing the collection box 5 onto the moving plate 4, the second limiting frame 12 can be rotated to a vertical position to avoid obstruction. After the movement is completed, the valve at the bottom of the spray drying tower 2 is opened to let the dry suspension fall into the collection box 5. After the collection is completed, the collection box 5 is pulled out.

[0027] Working principle: After the dry suspension is dried, the collection box 5 is placed in the groove of the moving plate 4. Then, the operator pushes the push-pull handle 8 to move the moving plate 4 forward. When the side of the collection box 5 contacts the spray drying tower 2, the collection box 5 is located directly below the spray drying tower 2. After placement, the push-pull handle 8 can be rotated to 90 degrees and hooked into the pull groove of the push-pull handle 8 by the hook 10. When the collection box 5 moves back and forth, the limit frame 11 and limit frame 2 12 can block the front and back of the collection box 5 to prevent the collection box 5 from sliding out due to inertia. After the movement is completed, the collection is carried out and then pulled out.
