Description
Technical Field
[0001] The utility model relates to the field of starch fine screening, in particular to an anti-blocking type starch fine screening device. Background Art
[0002] Starch is a high-molecular carbohydrate, a polysaccharide composed of a single type of sugar unit. Starch screening is a method used to detect starch quality. It determines the starch particle size distribution and screening rate by passing starch samples through sieves with different aperture sizes and calculating the weight of residual starch on each sieve. This can help manufacturers evaluate the purity and quality of starch for further handling and processing.
[0003] Most of the existing starch screening equipment is composed of a feed port, a motor, a screening box and a screen plate. Workers put the starch raw materials to be screened into the screening box through the feed port, so that the starch raw materials pass through the screen and are discharged from the discharge port to achieve the screening of the flour.
[0004] However, most of the existing starch screening equipment can only control the vibration of the screen by a motor when screening starch, so as to achieve the purpose of shaking out the agglomerated flour and screening it. However, when encountering starch clumps that are tightly adhered or large in size, it is difficult to effectively break them up by shaking alone, resulting in larger starch clumps clogging the sieve holes of the screen, affecting its overall screening efficiency. Workers are subsequently required to manually pick them out or press them to crush them, which is inconvenient. Utility Model Content

[0012] The utility model is further configured that a movable groove for the movable screen plate to move is opened inside the screening box, and a second limiting rod for limiting the pulling plate is fixedly installed at one end of the screening box.
[0013] By adopting the above technical solution, the movable groove provides space for the movable screen plate to move inside the screening box, and the second limit rod can limit the pull plate to prevent it from rotating along with the reciprocating screw rod.
[0014] The utility model is further configured that a movable rod is movably installed inside the screening box, and a pressure block is fixedly installed at one end of the movable rod, and a second spring connected to the screening box and the pressure block is sleeved outside the movable rod.
[0015] By adopting the above technical solution, the movably installed movable rod can drive the pressure block to move inside the screening box, so that the overall position of the pressure block will move upward when the slider is squeezed. After the slider is separated from the pressure block, the second spring controls the pressure block to reset, thereby knocking on the fixed screen plate and improving the overall discharge efficiency.

At the same time, during the reciprocating movement of the slider, the pressing block is intermittently squeezed to control its position, and when it is no longer in contact with the pressing block during the movement, the second spring applies elastic force to it to make it hit the fixed sieve plate. Compared with traditional screening equipment, the utility model can save the subsequent workers from manually crushing large starch agglomerates, effectively prevent large starch agglomerates from clogging the sieve holes, and improve the overall screening and discharge efficiency.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0027] The following describes an embodiment of the utility model based on its overall structure.
[0028] A kind of anti-blocking starch fine screening equipment, such as Figure 1-4As shown, it includes a support frame 1, a screening box 2 is fixedly installed at one end of the support frame 1, and a motor 3 is fixedly installed at one end of the screening box 2, a reciprocating screw rod 4 is fixedly connected to the output end of the motor 3, and a slider 5 is movably installed at one end of the reciprocating screw rod 4, a feeding port 24 is fixedly installed at one end of the screening box 2, a rotating shaft 6 is movably installed inside the slider 5, and a crushing wheel 7 is fixedly installed outside the rotating shaft 6, a fixed screen plate 9 is fixedly installed inside the screening box 2, and a first limiting rod 10 for limiting the slider 5 is fixedly installed inside the screening box 2, a scraper 8 is fixedly installed at one end of the slider 5, and the inside of the screening box 2 The part is movably equipped with an auxiliary component to prevent flour from being blocked. The worker puts the starch raw material into the interior of the screening box 2 through the feeding port 24, and starts the motor 3 to drive the reciprocating screw 4 to rotate, so that the slider 5 drives the crushing wheel 7 to repeatedly move on the end surface of the fixed screen plate 9 to crush the large pieces of starch. At the same time, when it moves to one end of the screening box 2, the slider 5 will squeeze the pressing block 21 to move its position upward. After it is no longer in contact with the pressing block 21, it is controlled by the second spring 20 to reset it, so that the pressing block 21 knocks on the fixed screen plate 9, causing it to vibrate and increase its discharge speed.
[0029] See also Figure 1 - Figure 3 The auxiliary components include a movable screen plate 11, a limit block 12, a pull plate 13, a connecting rod 15, a limit groove 23, a first spring 16 and a movable groove 17. The movable screen plate 11 is movably installed inside the screening box 2, and the connecting rod 15 is movably installed inside the support frame 1. The outer sleeve of the connecting rod 15 is provided with a first spring 16 connected to the screening box 2 and the movable screen plate 11. A pull plate 13 is movably installed at one end of the reciprocating screw rod 4. The movably installed movable screen plate 11 allows it to move inside the screening box 2. The movable screen plate 11 is squeezed by the first spring 16. When it moves along the connecting rod 15, the first spring 16 will continue to apply elastic force to it. When the squeezing or thrust is released, the movable screen plate 11 is controlled to reset, and the agglomerated starch agglomerates are squeezed together with the fixed screen plate 9 to prevent them from clogging the screen holes.
[0030] See also Figure 2 - Figure 3 A limiting block 12 is fixedly installed at one end of the movable screen plate 11, and a limiting groove 23 for limiting the limiting block 12 is opened inside the screening box 2. The movable screen plate 11 is limited by the limiting block 12 and the limiting groove 23 to control its moving direction and distance, thereby ensuring that it can normally screen the starch and break the starch agglomerates.
[0031] See also Figure 2 - Figure 3A movable groove 17 for the movable screen plate 11 to move is opened inside the screening box 2. A second limiting rod 14 for limiting the pull plate 13 is fixedly installed at one end of the screening box 2. The movable groove 17 provides space for the movable screen plate 11 to move inside the screening box 2. The second limiting rod 14 can limit the pull plate 13 to prevent it from rotating together with the reciprocating screw rod 4.
[0032] See also Figure 2 - Figure 4 A movable rod 19 is movably installed inside the screening box 2, and a pressure block 21 is fixedly installed at one end of the movable rod 19. A second spring 20 connected to the screening box 2 and the pressure block 21 is sleeved on the outside of the movable rod 19. The movably installed movable rod 19 can drive the pressure block 21 to move inside the screening box 2, so that the overall position of the slider 5 will move upward when the slider 5 is squeezed. After the slider 5 is separated from it, it is controlled to reset by the second spring 20, thereby knocking on the fixed screen plate 9 and improving its overall discharge efficiency.
[0033] See also Figure 1 - Figure 4 A through hole 22 is provided inside the screening box 2 for the pressing block 21 to move, and one side end face of the pressing block 21 is arranged in an arc shape. An extension block 18 is fixedly installed at one end of the movable screen plate 11, and a discharge port 25 is fixedly installed at one end of the screening box 2. The through hole 22 provides space for the pressing block 21 to move inside the screening box 2. The extension block 18 can extend the position of the fixed screen plate 9, so that the pressing block 21 can better knock it to make it vibrate.
[0034] The working principle of the utility model is as follows: when a worker uses the device to screen starch, he puts the starch raw material into the inside of the screening box 2 through the feeding port 24, starts the motor 3 to drive the reciprocating screw rod 4 to rotate, so that the slider 5 drives the crushing wheel 7 to repeatedly move on the end surface of the fixed screen plate 9 to crush the large starch clumps. At the same time, when it moves to one end of the screening box 2, the slider 5 will squeeze the pressing block 21 to move its position upward. After it is no longer in contact with the pressing block 21, it is controlled by the second spring 20 to reciprocate. The pressing block 21 strikes the fixed screen plate 9 to make it vibrate and increase its discharge speed. When the reciprocating screw 4 rotates, the pulling plate 13 is controlled to move, thereby pulling the movable screen plate 11 to move. Since the sieve holes of the movable screen plate 11 are different in size from those of the fixed screen plate 9, the starch clumps that fall to the end surface of the movable screen plate 11 but cannot pass through the movable screen plate 11 during its movement will be squeezed and crushed, and the starch that has been screened will be blocked by the sieve holes and discharged from the interior of the screening box 2 through the discharge port 25, thereby completing the screening of the starch.
