DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0040] Please refer to Figures 1-10 The application provides the following technical solutions:

[0041] Embodiment 1: In order to solve the problems existing in the production of benzohydroxamic acid, the following technical solution is disclosed in this embodiment, a raw material precise proportioning and adding device for benzohydroxamic acid production, comprising an adding device body 1, and storage barrel bodies 2 fixedly installed on the left and right sides inside the adding device body 1 for storing benzohydroxamic acid production raw materials; an adding mechanism is arranged on the outside of the adding device body 1, and the adding mechanism comprises a separation insert plate 3, and the separation insert plate 3 is slidably arranged at equal distances inside the left and right storage barrel bodies 2; wherein the separation insert plates 3 arranged at equal distances control the quantitative separation and feeding of the raw materials by sliding.

[0042] The adding mechanism includes a guide cone 5, which is fixedly installed on the top of the left and right storage tanks 2. The guide cone 5 guides the raw materials placed inside the guide bucket 4. The symmetrically arranged storage tanks 2 have a hollow cylindrical structure, which facilitates the addition of raw materials. The adding mechanism includes a positioning liner 6, which is fixedly installed on the front and rear sides of the adding device body 1. A lifting screw 7 is rotatably installed at the center of the positioning liner 6 through a bearing. The outer wall of the lifting screw 7 is threadedly connected to the inner end of the opening and closing bracket 8.

[0043] The adding mechanism includes a solenoid valve plate 9, which is fixedly installed on the inner side of the end of the front and rear opening and closing brackets 8 away from the adding device body 1. The solenoid valve plate 9 is connected to the power supply module 10 through a transmission cable 11, and the power supply module 10 is fixedly installed on the left and right sides of the outside of the adding device body 1. The outer end of the partition plate 3 included in the adding mechanism slides through the left and right sides of the outside of the adding device body 1. The outer end of the partition plate 3 and the solenoid valve plate 9 after being energized are mutually induced. By changing the direction of the energization of the solenoid valve plate 9, an attraction and repulsion effect is formed between it and the partition plate 3, so that it slides inside the storage tank 2 to realize the storage and feeding of materials.

[0044] like Figures 3-4 As shown, when it is necessary to add raw materials in proportion through the storage tank 2 inside the main body 1 of the adding device, the storage tank 2 divides the space by the partition plates 3 arranged at equal intervals inside. During the storage process, the partition plate 3 at the bottom of the storage tank 2 is closed, while the other partition plates 3 above are open. Then, the raw materials after being guided are put into the corresponding storage tank 2 through the guide cone 5 by the guide bucket 4. The falling raw materials are blocked by the bottom partition plate 3 so that they are stored at the bottom inside the storage tank 2.

[0045] Furthermore, when it is necessary to separate and store raw materials, the power supply module 10 on the outside of the main body 1 of the adding device introduces positive current to the connected solenoid valve plate 9 through the transmission cable 11. At this time, the solenoid valve plate 9 and the outer end of the separating insert 3 are magnetically repelled, and the servo motor at the bottom of the positioning liner 6 drives the lifting screw 7 to rotate. The opening and closing bracket 8, which is threadedly connected to the lifting screw 7, is limited by the positioning liner 6 so that the opening and closing bracket 8 drives the solenoid valve plate 9 to move upward. The separating insert 3 located at the bottom is located inside the storage tank 2 and is not affected. After the solenoid valve plate 9 continues to move upward to the area divided by the separating insert 3 to store the raw materials, the corresponding separating insert 3 is moved into the storage tank 2 by the solenoid valve plate 9. The storage tank 2 separates the raw materials by the separating insert 3, and the quantity of raw materials after separation is controlled by the closing time of the separating insert 3.

[0046] When the raw materials inside the storage barrel body 2 are added, the opening and closing support 8 drives the electromagnetic valve plate 9 to move to the initial position at the bottom, and the power supply module 10 introduces reverse current to the connected electromagnetic valve plate 9 through the transmission cable 11, so that the electromagnetic valve plate 9 is attracted by the opposite magnetic end of the partition plug 3, and when the opening and closing support 8 drives the electromagnetic valve plate 9 to move from bottom to top, the corresponding partition plug 3 is driven to slide outward, thereby adding the stored raw materials downward, improving the convenience and accuracy of the addition.

[0047] In order to solve the problems existing in the production of benzohydroxamic acid, the following technical scheme is disclosed in this embodiment. The top of the adding device body 1 is provided with a dredging mechanism, and the dredging mechanism comprises a dredging rack 4 fixedly installed on the top surface of the adding device body 1. The dredging mechanism comprises dredging screens 23 fixedly installed on the left and right sides inside the dredging rack 4, and the top surfaces of the symmetrically arranged dredging screens 23 are each rotationally provided with a dredging roller 12, and the inside of each symmetrically arranged dredging roller 12 is rotationally provided with a transmission arc rod 13 through a bearing.

[0048] The dredging mechanism comprises a contact protruding rod 18, which is fixedly installed on the left and right sides above the guide sliding groove 14 at equal distances. The bottom end of the contact protruding rod 18 is in contact with the moving transmission arc rod 13, which drives the transmission arc rod 13 and the dredging roller 12 to move downward to extrude the raw materials on the top surface of the dredging screen 23. The dredging mechanism comprises a contact sliding rod 19, which is symmetrically installed on the left and right sides inside the dredging rack 4 in two groups, and is connected with the dredging rack 4 through a contact spring 20. The contact sliding rod 19 is in contact with the moving transmission arc rod 13, which drives the contact sliding rod 19 to slide outward. The dredging mechanism comprises a feeding inclined plate 21, which is symmetrically and elastically slid on the left and right sides inside the dredging rack 4, and the outer end of the feeding inclined plate 21 is connected with the outer end of the contact sliding rod 19 through a traction steel cable 22. The contact sliding rod 19 slides outward, which drives the feeding inclined plate 21 to move inward to dredge the residual raw materials and prevent omission.

[0049] As Figures 5-6 , Figure 8As shown, when the raw materials are dredged, different raw materials are put into the dredging frame 4, and multiple raw materials can be processed at the same time. The reciprocating screw rod 15 installed in the dredging frame 4 is controlled by a servo motor, so as to drive the threaded guide block 16 to move in the guide sliding groove 14, and the transmission arc rod 13 connected to the left and right sides of the guide block 16 through the elastic slide rod 17 is driven to move back and forth to crush and dredge the raw materials remaining above the dredging screen 23, so as to avoid the blockage caused by the agglomeration and caking of the raw materials.

[0050] As shown in Figures 5-6 , when the guide block 16 drives the transmission arc rod 13 to move back and forth in the guide sliding groove 14, the transmission arc rod 13 contacts the contact protruding rod 18 arranged at equal distances, so that the transmission arc rod 13 drives the dredging roller 12 to move downward and crush the raw materials above the dredging screen 23, so as to improve the dredging effect and the efficiency of adding the raw materials.

[0051] As shown in Figure 7 , Figures 9-10 , during the movement of the dredging roller 12 and the transmission arc rod 13 in the dredging frame 4, the contact sliding rod 19 is extruded, so that the contact sliding rod 19 moves outward to tension the traction cable 22, the other end of the traction cable 22 drives the fixedly connected feeding inclined plate 21 to slide inward, and then pushes the remaining raw materials to the side close to the dredging roller 12, and cooperates with the dredging roller 12 to crush and put the raw materials, so as to avoid the pollution caused by the remaining raw materials during the subsequent work.

[0052] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments, or make equivalent replacements to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
