Description

Technical Field

[0001] This utility model relates to the field of seed crystallization granulation technology, specifically to a seed crystal feeding device for crystallization granulation. Background Technology

[0002] Seed crystals provide sites for crystal growth, enabling the formation of crystal nuclei from a homogeneous, single-phase solution by overcoming an energy barrier. The addition of seed crystals accelerates the growth rate of the target crystal form, contributing to its formation. In industrial production, to obtain large-grained and uniform crystals, primary nucleation must be avoided as much as possible, and secondary nucleation must be controlled. Adding an appropriate amount of seed crystals as the core for crystal growth is usually essential, making seed crystal preparation a crucial step in crystal manufacturing.

[0003] In the crystallization and granulation process, seed crystals need to be transported from storage equipment to processing equipment. However, existing conveying equipment is not convenient for timely and quantitative feeding of seed crystal raw materials. It is also impossible to replenish seed crystal raw materials during operation. Furthermore, it is necessary to avoid the formation of clumps due to prolonged storage of seed crystal raw materials. Therefore, clumps may block the conveying pipeline during transportation, affecting the continuous operation of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a seed crystal feeding device for crystallization and granulation, which solves the problem that existing conveying equipment is inconvenient for timely and quantitative feeding of seed crystal raw materials, and it is impossible to replenish seed crystal raw materials during operation. Secondly, it avoids the problem that seed crystal raw materials may form clumps after being stored for a long time, which may block the conveying pipes during transportation and affect the continuous operation of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a seed crystal feeding device for crystallization granulation, comprising: a seed crystal storage tank, a frame for support and installation fixedly connected to the bottom of the seed crystal storage tank, a seed crystal mixing box fixedly connected to one side of the top of the frame, a mixing container for seed crystal mixing fixedly connected to the surface of the seed crystal mixing box, and a mixing sealing cover movably connected to the surface of the seed crystal mixing box for stirring and mixing the seed crystals and sealing the mixing container, a funnel for feeding fixedly connected to the top of the mixing sealing cover, a conveying pipe provided at the top of the funnel, and the other end of the conveying pipe fixedly connected to the seed crystal storage tank, the conveying pipe being used to convey the seed crystals from the seed crystal storage tank to the inside of the mixing container;

[0006] The seed storage tank is internally connected to a seed dispensing mechanism, and a limit mechanism is fixedly connected to the surface of the seed dispensing mechanism.

[0007] An electrical control box is fixedly connected to the top of the frame, and the electrical control box is electrically connected to the seed delivery mechanism, the limiting mechanism and the seed mixing box through wires.

[0008] The aforementioned seed crystal feeding mechanism includes a connecting shaft, a control motor, a pusher seat, a sleeve, a sliding block, and a retractable protective tube. The bottom end of the connecting shaft is fixedly connected to the output end of the control motor via a coupling. The sleeve is fixedly connected to the middle position of the pusher seat, and the pusher seat is circular. The sliding block is movably connected to the top end of the sleeve via a bearing. The retractable protective tube is sleeved on the outside of the connecting shaft, and the bottom end of the retractable protective tube is fixedly connected to the top end of the sleeve.

[0009] As described above, the control motor is fixedly connected to the bottom of the seed storage tank, the two ends of the connecting shaft are movably connected to the two ends inside the storage tube through bearings, and the bottom end of the connecting shaft passes through the seed storage tank and is fixedly connected to the output of the control motor. The outer side of the connecting shaft is threaded, and the sliding block is movably connected to the connecting shaft through the thread. The sleeve is sleeved on the outer side of the connecting shaft, and the outer side of the push seat is slidably connected to the inside of the seed storage tank.

[0010] The aforementioned seed feeding mechanism further includes a push bar and a crushing bar. The push bar has several pieces arranged in a ring and uniformly fixedly connected to the outer top of the connecting shaft. The push bar is S-shaped. The crushing bar has several pieces, and the crushing bars are respectively fixedly connected to the inner side of the push bar and the connecting section of the connecting shaft. One side of the crushing bar is triangular.

[0011] The aforementioned limiting mechanism includes an electric push rod, a drive bar, a control bar, a connecting frame, a push rod, a return spring, and a limiting bar. The drive bar is fixedly connected to the telescopic end of the electric push rod, and one end of the control bar is movably connected to both ends of the drive bar via a rotating shaft. The push rod has two rods that pass through the connecting frame, and the ends of the control bars away from the drive rod are movably connected to one end of the push rod via rotating shafts. The return spring is located inside the connecting frame, and the return springs are respectively sleeved on the outside of the push rod. The limiting bars are fixedly connected to opposite sides of the push rod.

[0012] As described above, the top of the connecting frame is fixedly connected to the bottom of the pusher seat, the electric push rod is fixedly connected to the bottom of the pusher seat through a connector, the limiting strip is arc-shaped, and the inner side of the limiting strip is provided with limiting teeth.

[0013] As described above, a gear is fixedly connected to the outer side of the sliding block, and the gear and the limiting strip are located on the same cross section, and the gear and the limiting teeth are adapted to each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model controls a motor to drive a sliding block upward through a connecting shaft. Simultaneously, the sliding block pushes the sleeve upward through a sleeve, which slides along the same trajectory on the surface of the connecting shaft. Consequently, the pusher seat is pushed by the force to push the seed material stored inside the seed storage tank to the height of the conveying pipe connection port. During this process, the retractable protective tube moves upward with the sleeve and folds and retracts. Next, the motor drives the connecting shaft to rotate, which in turn drives the pusher bar to move the crushing bar. The crushing bar rotates and crushes the clumps in the seed material. At the same time, the pusher bar stirs the seed material and pushes it to the opening of the conveying pipe until the seed material falls into the mixing container through the conveying pipe and the funnel. This facilitates the timely and quantitative feeding of seed material and allows for real-time replenishment of seed material. Furthermore, it avoids the formation of clumps from the seed material after prolonged storage, which could block the pipeline during conveying.

[0016] 2. This utility model controls the retraction of the electric push rod's telescopic end. At this time, the two ends of the drive bar pull the control bar, causing its other end to move closer to the opposite side. Simultaneously, the return spring exerts a reaction force on the limit bar, and the push rod moves to the opposite side at the same time until the limit bar drives the limit teeth and gears to mesh with each other. This helps ensure the stability of the equipment when the seed material feeding stops. Secondly, it avoids the seed material pressing down on the push seat, which would cause changes in the pushing height and increase the friction between the sliding block and the connecting shaft, resulting in damage to the threads and affecting subsequent operations.

The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] Please see Figures 1 to 4 The present invention preferably provides the following technical solution: a seed crystal feeding device for crystallization granulation, comprising: a seed crystal storage tank 1, a frame 2 for support and installation fixedly connected to the bottom of the seed crystal storage tank 1, a seed crystal mixing box 3 fixedly connected to one side of the top of the frame 2, a mixing container 4 for seed crystal mixing fixedly connected to the surface of the seed crystal mixing box 3, and a mixing sealing cover 5 movably connected to the surface of the seed crystal mixing box 3 for stirring and mixing the seed crystals and sealing the mixing container 4, a funnel 6 for feeding material fixedly connected to the top of the mixing sealing cover 5, a conveying pipe 7 provided at the top of the funnel 6, and the other end of the conveying pipe 7 fixedly connected to the seed crystal storage tank 1, the conveying pipe 7 being used to convey the seed crystals from the seed crystal storage tank 1 to the inside of the mixing container 4;

[0025] The seed storage tank 1 is internally connected to a seed dispensing mechanism 8, and a limit mechanism 9 is fixedly connected to the surface of the seed dispensing mechanism 8;

[0026] An electrical control box 10 is fixedly connected to the top of the frame 2, and the electrical control box 10 is electrically connected to the seed delivery mechanism, the limiting mechanism 9 and the seed mixing box 3 through wires.

[0027] Example 2

[0028] Please see Figure 1 , Figure 2 and Figure 3The preferred technical solution provided by this utility model is as follows: The seed crystal feeding mechanism 8 includes a connecting shaft 801, a control motor 802, a pusher seat 803, a sleeve 804, a sliding block 805, and a retractable protective tube 806. The bottom end of the connecting shaft 801 is fixedly connected to the output end of the control motor 802 via a coupling. The sleeve 804 is fixedly connected to the middle position of the pusher seat 803, and the pusher seat 803 is circular. The sliding block 805 is movably connected to the top end of the sleeve 804 via a bearing. The retractable protective tube 806 is sleeved on the outside of the connecting shaft 801 and is retractable and protective. The bottom end of the protective tube 806 is fixedly connected to the top end of the sleeve 804. The control motor 802 is fixedly connected to the bottom of the seed storage tank 1. The two ends of the connecting shaft 801 are movably connected to the two ends inside the storage tube through bearings. The bottom end of the connecting shaft 801 passes through the seed storage tank 1 and is fixedly connected to the output of the control motor 802. The outer side of the connecting shaft 801 is threaded, and the sliding block 805 is movably connected to the connecting shaft 801 through the thread. The sleeve 804 is sleeved on the outer side of the connecting shaft 801. The outer side of the pusher seat 803 is slidably connected to the inside of the seed storage tank 1.

[0029] By controlling the motor 802, it drives the sliding block 805 to slide upward through the connecting shaft 801. At the same time, the sliding block 805 pushes the sleeve 804 upward through the sleeve 804 to slide along the same trajectory on the surface of the connecting shaft 801. Consequently, the pusher seat 803 is pushed by the force to push the seed material stored inside the seed storage tank 1 to the height of the connection port of the conveying pipe 7. During this process, the retractable protective tube 806 moves upward with the sleeve 804 and folds and retracts at the same time, which is conducive to convenient control of the timed and quantitative feeding of seed material and real-time replenishment of seed material.

[0030] The seed crystal feeding mechanism 8 also includes a push bar 807 and a crushing bar 808. The push bar 807 has several bars arranged in a ring and is evenly fixedly connected to the outer top of the connecting shaft 801. The push bar 807 is S-shaped. The crushing bar 808 has several bars, and the crushing bars 808 are respectively fixedly connected to the connecting section between the inner side of the push bar 807 and the connecting shaft 801. One side of the crushing bar 808 is triangular.

[0031] By controlling the motor 802 to drive the connecting shaft 801 to rotate, the pusher bar 807 drives the crushing bar 808 to move. The crushing bar 808 rotates and crushes the clumps in the seed crystal material. At the same time, the pusher bar 807 stirs the seed crystal material and pushes it to the opening of the conveying pipe 7 until the seed crystal material falls into the mixing container 4 through the conveying pipe 7 and the funnel 6 in sequence. This prevents the seed crystal material from clumping together after being left for a long time, which could block the pipeline during conveying.

[0032] Example 3

[0033] Please see Figure 1 and Figure 4The preferred technical solution provided by this utility model is as follows: The limiting mechanism 9 includes an electric push rod 901, a drive bar 902, a control bar 903, a connecting frame 904, a push rod 905, a return spring 906, and a limiting bar 907. The drive bar 902 is fixedly connected to the telescopic end of the electric push rod 901, and one end of the control bar 903 is movably connected to both ends of the drive bar 902 via a rotating shaft. The push rod 905 has two rods that pass through the connecting frame 904, and the ends of the control bars 903 away from the drive bar 902 are movably connected to one end of the push rod 905 via a rotating shaft. The return spring 906 is located inside the connecting frame 904, and the return spring 906 is sleeved on the outside of the push rod 905. The limiting bars 907 are fixedly connected to the opposite sides of the push rod 905.

[0034] By controlling the retraction of the telescopic end of the electric push rod 901, the two ends of the drive bar 902 pull the control bar 903, causing its other end to move closer to the opposite side. At the same time, the return spring 906 exerts a reaction force on the limit bar 907, and the push rod 905 moves to the opposite side simultaneously until the limit bar 907 drives the limit tooth 12 and the gear 11 to mesh with each other, thus preventing the seed material from pressing down on the push seat 803, which would cause changes in the push height and increase the friction between the sliding block 805 and the connecting shaft 801, resulting in damage to the threads and affecting subsequent operations.

[0035] The top of the connecting frame 904 is fixedly connected to the bottom of the push seat 803, the electric push rod 901 is fixedly connected to the bottom of the push seat 803 through the connector, the limiting strip 907 is arc-shaped, and the inner side of the limiting strip 907 is provided with limiting teeth 12.

[0036] The connecting frame 904 drives the push rod 905 to move the limit bar 907 and the push seat 803 along the same trajectory, so as to avoid the position of the limit tooth 12 and the gear 11 changing, which would prevent the limit operation from being performed later.

[0037] A gear 11 is fixedly connected to the outside of the sliding block 805, and the gear 11 and the limiting strip 907 are located on the same cross section. The gear 11 is adapted to the limiting tooth 12.

[0038] The push rod 905 moves simultaneously to the opposite side until the limit bar 907 drives the limit tooth 12 and the gear 11 to mesh with each other, and the equipment stops feeding seed crystal raw materials, thus ensuring the stability of the equipment.

[0039] Based on the above embodiments 1, 2, and 3, the working principle is further described. In use, the control motor 802 is remotely started via the control box 10, causing it to drive the sliding block 805 upwards via the connecting shaft 801. Simultaneously, the sliding block 805 pushes the sleeve 804 upwards via the sleeve 804, causing the sleeve 804 to slide along the same trajectory on the surface of the connecting shaft 801. Consequently, the pusher seat 803 receives a pushing force, pushing the seed material stored inside the seed storage tank 1 to the height of the connection port of the conveying pipe 7. During this process, the retractable protective tube 806 moves upwards along with the sleeve 804 while simultaneously folding and retracting. Next, the control motor 802 drives the connecting shaft 801 to rotate, driving the pusher bar 80... 7 drives the crushing bar 808 to move remotely, and the crushing bar 808 rotates and crushes the agglomerates in the seed crystal raw material. At the same time, the pushing bar 807 stirs the seed crystal raw material and pushes it to the opening of the conveying pipe 7 until the seed crystal raw material falls into the mixing container 4 through the conveying pipe 7 and the funnel 6 in sequence. When the control motor 802 stops, the electrical control box 10 controls the extension end of the electric push rod 901 to retract. At this time, the two ends of the drive bar 902 pull the control bar 903, so that its other end moves closer to the opposite side. At the same time, the return spring 906 reacts to the limiting bar 907, and the pushing rod 905 moves to the opposite side at the same time until the limiting bar 907 drives the limiting tooth 12 to mesh with the gear 11.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part. Among these, there are various ways to install detachably, such as by using a combination of plug-in and snap-fit, or by using bolts for connection, etc.

[0041] In addition, all the connections / connections mentioned in the article do not refer to direct connection of components, but rather to the formation of a better connection structure by adding or removing connecting accessories according to the specific implementation situation.

[0042] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model.
