Description

Technical Field

[0001] This utility model relates to the field of modified starch production and processing, and in particular to a modified starch cyclone recovery tail material collection device. Background Technology

[0002] The current production process for modified starch involves reconfiguring the produced starch into a starch slurry, then adding it to a reaction vessel along with various chemical raw materials. After heating and stirring for a certain period, the mixture undergoes refining, dehydration, drying, and recycling / packaging processes to produce the final product. The recycling / packaging process involves using pipelines to transport the air-dried starch into a...

[0003] The starch is fed into a cyclone separator, and after separation, it enters a vibrating screen. The vibrating screen separates the coarse starch particles to obtain high-quality fine starch. For the specific principle, please refer to the applicant's previous utility model patent application CN202323228394X. After the cyclone separator separates and recovers the dry starch, the tail flow is discharged through the exhaust pipe at its upper end. However, some starch will remain in the tail flow. Currently, it is usually reintroduced into the drying pipeline and then re-enter the cyclone separator for recovery. This method causes some residual starch to be repeatedly dried, which is not conducive to improving drying and recovery efficiency and reducing energy consumption, and needs to be improved. Utility Model Content

[0005] The technical solution of this utility model is: a modified starch cyclone recovery tail material collection device, including a cyclone separator and a collection box. A cross support plate is provided along the cross-section of the upper middle part of the collection box. The cross support plate adopts a movable installation structure, which is convenient for installation and disassembly. Several circular holes are evenly provided on the surface of the cross support plate, covering the entire area of ​​the cross support plate. A dust filter is installed in the circular hole and extends downward into the collection box. The length of the dust filter is selected according to the requirements. An air outlet is provided on the side wall of the box corresponding to the upper space of the cross support plate. An exhaust pipe is connected to the air outlet. An air inlet is provided on the side plate of the box at the lower part of the cross support plate. The exhaust pipe on the upper end of the cyclone separator is connected to the air inlet. The lower end of the exhaust pipe is connected to a pipe joint through a circular flange. The pipe joint and the air inlet are an integral structure. The lower end of the collection box is connected to a flow guide box through a flange. The lower end of the flow guide box is connected to a feeding mechanism.

[0006] Preferably, the dust filter includes a support frame and a synthetic fiber felt covering the outer side of the support frame. It is necessary to ensure the airtightness between the synthetic fiber felt and the round hole to avoid air leakage.

[0007] Preferably, the feeding mechanism includes a U-shaped material trough connected to the lower port of the guide box via a flange plate. The length of the material trough is greater than the size of the lower port of the guide box. A motor support is provided on the end plate at one end of the material trough, and protective ear plates are provided on both sides of the motor support. A bearing seat is provided on the end plate at the other end. A spiral auger is provided inside the material trough. One end of the main shaft of the spiral auger is connected to the bearing seat. The main shaft is a stepped shaft. The other end is connected to a geared motor installed on the motor support. A discharge nozzle is provided on the bottom surface of the end of the material trough away from the geared motor. The discharge nozzle is perpendicularly connected to the material trough.

[0008] Preferably, the collection box is provided with a conical air control hood in the middle. The large-sized port of the conical air control hood is fixedly connected to the inner side wall of the collection box.

[0011] The beneficial technical effects of this utility model are:

[0012] (1) The device introduces the tail of the cyclone separation into a sealed collection box. The tail flows upward in the collection box and passes through a densely arranged dust filter. The dust filter filters out the residual starch, which adheres to the surface of the synthetic fiber felt. After accumulation, it falls into the guide box below and is fed out at a uniform speed and in a quantitative manner by a screw feeding mechanism for collection. This effectively solves the problem of repeated drying of residual starch, which is conducive to improving drying and recovery efficiency and reducing energy consumption.

[0013] (2) The device reduces the lateral impact force of the tail flow by setting a conical air control hood, so that it decelerates from the lower port of the air control hood and covers the entire dust filter area, which helps to improve the uniformity of filtration and collection between each dust filter, avoids the phenomenon of local dust filter blockage, and improves the filtration and collection effect.

Detailed Implementation

[0019] Example 1, see appendix Figure 1-4 A modified starch cyclone recovery tail material collection device includes a cyclone separator 1 and a collection box 2. A cross-bracing plate 21 is provided along the cross-section of the upper middle part of the collection box. The surface of the cross-bracing plate is evenly provided with several circular holes, each containing a dust filter. The tail flow, mixed with starch, passes through the dust filter and enters the upper region of the collection box 2 through the circular holes. The dust filter extends downwards into the collection box 2 through the circular holes. An air outlet 23 is provided on the side wall of the box corresponding to the upper space of the cross-bracing plate 21. After passing through… The tail flow after each dust filter is discharged from the air outlet 23, which can effectively avoid dust pollution. The side plate of the box at the lower part of the cross support plate 21 is provided with an air inlet 24. The exhaust pipe 11 on the upper end of the cyclone separator 1 is connected to the air inlet 24. After the cyclone separator 1 separates and recovers the starch dried by the airflow, the tail flow enters the collection box 2 from the air inlet 24. The lower port of the collection box 2 is connected to the guide box 3 through a flange. The lower port of the guide box 3 is connected to the feeding mechanism.

[0020] The dust filter includes a support frame 221 and a synthetic fiber felt 222 covering the outer side of the support frame.

[0021] A vibration motor A 61 is provided in the middle of the outer side of the flow guide box 3. The vibration motor A is used to generate vibration force on the flow guide box 3, so that the starch falling on the inner side of the flow guide box quickly falls to the feeding mechanism below. A vibration motor B 62 is provided on the outer side of the collection box 2. The vibration motor B corresponds to the position of the dust filter. The vibration motor B 62 is used to generate vibration force on each dust filter, so that the attached starch falls off and avoids clogging.

[0022] Example 2, see appendix Figure 1-2This embodiment is basically the same as Embodiment 1, except that: the feeding mechanism includes a U-shaped material trough 41 connected to the lower port of the guide box 3 via a flange plate. One end plate of the material trough is provided with a motor support 42, and the other end plate is provided with a bearing seat 43. A spiral auger 44 is provided inside the material trough 41. One end of the main shaft of the spiral auger is connected to the bearing seat 43, and the other end is connected to a reduction motor 45 installed on the motor support 42. A discharge nozzle 411 is provided on the bottom surface of the end of the material trough 41 away from the reduction motor. Starch sliding down from the guide box 3 enters the feed trough 41 from the lower port. After the feed trough 41 and the lower space of the guide box 3 are filled with starch, the geared motor 45 is started to drive the bolt auger to rotate. The auger 44 pushes the starch continuously towards the discharge nozzle 411. A container is placed below the discharge nozzle 411 for collection. The auger 44 in this feeding mechanism has a sealing effect, so there is no need to set a sealing cap at the port. The drive motor can realize starch recovery, which is convenient and fast. It also has the advantage of uniform and quantitative feeding, which improves the efficiency and convenience of tail material recovery.

[0023] When the collection device of this embodiment is in use, the cyclone separator 1 introduces the tail flow of starch dried by airflow into the collection box 2. The tail flow flows upward in the collection box 2 and passes through the densely arranged dust filters. The dust filters filter out the residual starch and it adheres to the surface of the synthetic fiber felt 222. After the starch accumulates on the surface, it falls to the guide box 3 below and slides quickly to the lower outlet under the action of the vibrating motor A 61. When the starch accumulates to a certain amount, the screw feeding mechanism feeds it out at a uniform speed and in a quantitative manner for collection. It has the advantages of high drying and recovery efficiency and low energy consumption.

[0024] Example 3, see appendix Figure 2 This embodiment is basically the same as Embodiment 1, except that: a conical air control hood 5 is provided in the middle of the collection box 2. The large-size port of the conical air control hood is fixedly connected to the inner side wall of the collection box 2, and the small-size port is located in the center of the collection box 2. The tail flow enters upward from the small-size port into the space between each dust collector. The conical air control hood 5 is set between the dust filter and the air inlet 24. The exhaust pipe 11 extends from the air inlet 24 into the collection box 2 and faces the outer side of the conical air control hood 5. The tail flow discharged from the exhaust port is blocked by the conical air control hood 5 and flows downward, and then enters the filtration and dust removal area upward from the small-size port.

[0025] This embodiment reduces the lateral impact force of the wake by setting a conical air control hood 5, causing it to decelerate upwards from the lower port of the air control hood and cover the entire dust filter area. This helps to improve the uniformity of filtration and collection among the various dust filters, avoids the phenomenon of local dust filter blockage, and improves the filtration and collection effect.
