Description

Technical Field

[0001] The utility model belongs to the technical field of starch ether processing, and particularly relates to a feeding device for starch ether processing. Background Technique

[0002] Starch ether is a kind of starch derivative, usually used as an adhesive, thickening agent and emulsifier. It is a kind of polymer synthesized by reacting starch with iodine and then with oxidation. Starch ether is widely used in various products in industry, such as building materials, food, medicine, textiles, etc. When producing and processing starch ether, it is necessary to feed materials into the reaction kettle through a feeding device.

[0003] In the prior art, there is a feeding device for starch ether processing with the patent publication number of CN219272995U. The above patent includes a storage tank. The bottom end of the storage tank is fixedly installed with a crushing tank. The bottom of the crushing tank is provided with a reaction kettle. A visual window is embedded in the front of the storage tank. The top end of the storage tank is fixedly installed with a mounting frame. One side of the inner wall of the crushing tank is rotatably installed with two gears. The outer walls of the two gears are meshed. One end of each of the two gears is fixedly connected with a stirring rod. A plurality of stirring blades are fixedly connected to the outer walls of the two stirring rods. When the rack moves vertically, it meshes with the adjacent gear and can drive the two stirring rods to rotate synchronously under the meshing of the other gear. Therefore, the two groups of stirring blades are driven to rotate. The rotation of the stirring blades assists in stirring the passing materials. Therefore, the agglomerated materials can be broken, or a variety of materials can be premixed first, so as to achieve a prefabrication effect, avoiding the influence on the reaction efficiency after the agglomerated materials or the materials that are not evenly mixed enter the reaction kettle. However, there are still the following deficiencies in actual use: Starting from reality, the device uses two groups of stirring blades to disperse the agglomerated starch ether, but the gap between the two groups of stirring blades is relatively large, and the residence time of starch ether at the top position of the two groups of stirring blades is short. Therefore, the dispersion effect is poor. At the same time, due to the too-fast feeding during material feeding, it is easy to cause blockage of the discharge port.

[0004] Therefore, a feeding device for starch ether processing is needed to solve the problems that the residence time of materials at the top position of the stirring blades is short and the stirring effect is insufficient, and the too-fast feeding is easy to cause blockage of the discharge port in the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to provide a feeding device for starch ether processing to solve the problems put forward in the above background technique.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding device for starch ether processing, comprising a feeding trough, a top of the feeding trough is fixedly connected to an upper hopper, a top of the upper hopper is rotatably connected to a cover plate, an observation window is provided at the front end of the feeding trough, a plurality of evenly distributed crushing plates are fixedly connected to the inner walls on both sides of the feeding trough near the top, a breaking mechanism corresponding to the crushing plates is arranged inside the feeding trough, a limiting slide groove is provided on the inner wall of the feeding trough, a filter frame is slidably connected to the inner wall of the limiting slide groove, two second drive motors are fixedly connected to the rear end of the feeding trough, two second drive motor output ends are fixedly connected to a second rotating shaft, two second rotating shaft outer walls are fixedly connected to two cams corresponding to the filter frame, a first guide plate is fixedly connected to the inner wall on one side of the feeding trough, and a second guide plate is fixedly connected to the inner wall on the other side of the feeding trough.

[0007] It should be noted in the solution that a torsion spring corresponding to the cover plate is installed on the top of the upper hopper.

[0008] It is further worth mentioning that the breaking up mechanism includes a first driving motor fixedly connected to the rear end of the feeding trough, the output end of the first driving motor is fixedly connected to a first rotating shaft, and the outer wall of the first rotating shaft is fixedly connected to a plurality of evenly distributed breaking up blades.

[0009] It should be further explained that the plurality of breaking blades and the plurality of crushing plates are staggeredly distributed.

[0010] As a preferred embodiment, the corners of the plurality of scattering blades and the corners of the plurality of crushing plates are chamfered.

[0011] As a preferred implementation, the tops of the two cams overlap with the bottom of the filter frame.

[0012] As a preferred implementation, the first material guide plate and the second material guide plate are both inclined.

[0013] Compared with the prior art, the feeding device for starch ether processing provided by the utility model has at least the following beneficial effects:

[0014] (1) By arranging a crushing plate and a dispersing mechanism in coordination, starch ether is poured from an upper hopper and stays in the top space between the crushing plate and the dispersing blades. The first driving motor is turned on to drive the first rotating shaft to rotate, so that the dispersing blades rotate to disperse the starch ether. The crushing plate and the dispersing blades are staggered, which prolongs the residence time of the starch ether in the top space between the crushing plate and the dispersing blades, thereby achieving a more complete dispersing effect.

[0015] (2) By setting the cam to cooperate with the filter frame, the dispersed starch ether falls onto the top of the filter frame. The second driving motor is turned on, and the second driving motor drives the cam to intermittently vibrate and strike the filter frame, causing the starch ether on the top of the filter frame to fall through the filter holes, and then the feeding work is completed through the first guide plate and the second guide plate, buffering the feeding of the starch ether to avoid blockage of the discharge port caused by too fast feeding.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The present utility model will be further described below in conjunction with the embodiments.

[0022] Please refer to Figures 1-4 , the present utility model provides a feeding device for starch ether processing, including a feeding trough 1, a feeding hopper 2 is fixedly connected to the top of the feeding trough 1, a cover plate 3 is rotatably connected to the top of the feeding hopper 2, an observation window 4 is opened at the front end of the feeding trough 1, a plurality of uniformly distributed crushing plates 5 are fixedly connected to both inner walls of the feeding trough 1 near the top, a dispersing mechanism 6 corresponding to the crushing plates 5 is arranged inside the feeding trough 1, a limiting chute 7 is opened on the inner wall of the feeding trough 1, a filter frame 8 is slidably connected to the inner wall of the limiting chute 7, two second driving motors 9 are fixedly connected to the rear end of the feeding trough 1, second rotating shafts 10 are fixedly connected to the output ends of the two second driving motors 9, two cams 11 corresponding to the filter frame 8 are fixedly connected to the outer walls of the two second rotating shafts 10, a first guide plate 12 is fixedly connected to one inner wall of the feeding trough 1, and a second guide plate 13 is fixedly connected to the other inner wall of the feeding trough 1.

[0023] Further, as shown in Figure 1 and Figure 2As shown, it is worth explaining in detail that a torsion spring corresponding to the cover plate 3 is installed on the top of the upper hopper 2 to ensure that the cover plate 3 can be flexibly opened and closed. The cover plate 3 is turned open to pour the starch ether. After pouring, the cover plate 3 is automatically closed under the action of the torsion spring to prevent the starch ether from escaping from the top of the upper hopper 2 during the breaking process.

[0024] Further Figure 3 As shown, it is worth explaining in detail that the tops of the two cams 11 overlap the bottom of the filter frame 8 to ensure that the rotation of the cams 11 can intermittently vibrate the filter frame 8, so that the filter frame 8 reciprocates up and down to vibrate the starch ether.

[0025] Further Figure 3 As shown, it is worth explaining in detail that the first guide plate 12 and the second guide plate 13 are both inclined, and the inclined design can buffer the feeding of starch ether to avoid too fast feeding.

[0026] According to the above working process, it can be known that: by setting the cam 11 and the filter frame 8 to cooperate, the broken starch ether falls into the top of the filter frame 8, and the second drive motor 9 is turned on. The second drive motor 9 drives the cam 11 to intermittently vibrate and strike the filter frame 8, so that the starch ether on the top of the filter frame 8 falls from the filter hole, and then passes through the first guide plate 12 and the second guide plate 13 to complete the feeding work, and buffer the discharge of the starch ether to avoid excessive discharge causing blockage of the discharge port.

[0027] Further Figure 4 As shown, it is worth explaining in detail that the breaking up mechanism 6 includes a first driving motor 601 fixedly connected to the rear end of the feeding trough 1, the output end of the first driving motor 601 is fixedly connected to a first rotating shaft 602, and the outer wall of the first rotating shaft 602 is fixedly connected to a plurality of evenly distributed breaking up blades 603. By setting up the breaking up mechanism 6, the agglomerated starch ether is broken up to facilitate the subsequent starch ether processing work.

[0028] Further Figure 4 As shown, it is worth explaining in detail that the multiple breaking blades 603 and the multiple crushing plates 5 are staggered, and the staggered distribution can prolong the residence time of the starch ether in the top space of the crushing plates 5 and the breaking blades 603, so that the breaking effect is more sufficient.

[0029] Further Figure 4 As shown, it is worth explaining in detail that the corners of the multiple breaking blades 603 and the corners of the multiple crushing plates 5 are chamfered. The chamfered design can make the starch ether fall more smoothly, so that the broken starch ether can fall smoothly into the top of the filter frame 8.

[0030] This solution has the following working process: During actual use, pour the starch ether into the hopper 2, and it stays in the top space between the crushing plate 5 and the dispersing blades 603. Turn on the first driving motor 601 to drive the first rotating shaft 602 to rotate, so that the dispersing blades 603 rotate to disperse the starch ether. The crushing plate 5 and the dispersing blades 603 are staggered to extend the residence time of the starch ether in the top space between the crushing plate 5 and the dispersing blades 603. The dispersed starch ether falls onto the top of the filter frame 8. Turn on the second driving motor 9, and the second driving motor 9 drives the cam 11 to intermittently vibrate and strike the filter frame 8, so that the starch ether on the top of the filter frame 8 falls through the filter holes, and then the feeding work is completed through the first guide plate 12 and the second guide plate 13.

[0031] In summary: By setting the dispersing mechanism 6, the agglomerated starch ether is dispersed, facilitating subsequent processing of the starch ether; by setting the cam 11 to cooperate with the filter frame 8, the dispersed starch ether falls onto the top of the filter frame 8, and then the feeding work is completed through the first guide plate 12 and the second guide plate 13, buffering the feeding of the starch ether to avoid blockage of the discharge port caused by too fast feeding.
