Description

Technical Field

[0001] This invention relates to a batching device and a batching method for a brine purification workshop. Background Technology

[0002] In the salt production process, the brine purification workshop generally uses the two-alkali method (sodium carbonate and sodium hydroxide) to purify the brine in order to obtain the qualified brine required for production.

[0003] In existing brine purification processes, materials need to be fed into a batching tank via a screw conveyor for processing. However, when too much material is fed into the screw conveyor hopper at once, blockages can easily occur, affecting batching efficiency. Therefore, this invention proposes a batching device and method for a brine purification workshop to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a batching device and method for a brine purification workshop to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A batching device for a brine purification workshop includes a batching screw conveyor, wherein a batching bucket is provided at the discharge port of the batching screw conveyor.

[0007] The feed hopper is provided at the feed inlet of the feed screw conveyor. Two sets of buffer plates are provided inside the feed hopper. A rotating rod is provided on the buffer plate. The rotating rod is rotatably mounted on the feed hopper. The buffer plate rotates about the axis of the rotating rod toward the bottom of the feed hopper, so that a gap appears between the two sets of buffer plates.

[0008] As an improvement to the above technical solution, two sets of support side plates are symmetrically arranged on the feed hopper, and two sets of rotating holes are opened on the support side plates.

[0009] The two ends of the rotating rod are respectively set on the rotating holes corresponding to the positions of the two sets of support side plates. The rotating rod rotates in the rotating holes, so that the buffer plate rotates about the axis of the rotating rod.

[0010] As an improvement to the above technical solution, both sets of rotating rods are provided with sector gears, and the two sets of sector gears mesh with each other;

[0011] A set of rotating rods is provided with a drive gear, which is fixedly connected to the rotating rod and is connected to an external drive motor through a gear timing belt.

[0012] As an improvement to the above technical solution, the buffer plate is provided with a barrier post, and two sets of barrier cavities are symmetrically arranged inside the barrier post.

[0013] The barrier cavity is provided with a barrier component, which is engaged with the surface of the support side plate.

[0014] As an improvement to the above technical solution, a barrier ring is provided inside the barrier cavity;

[0015] The barrier assembly includes a barrier rod, on which a movable rod is provided. The diameter of the movable rod is larger than the diameter of the barrier ring, and a spring is provided between the movable rod and the inner wall of the barrier cavity.

[0016] As an improvement to the above technical solution, two sets of barrier strips are provided on the support side plate. The barrier strips are symmetrically arranged on the support side plate, and the barrier rod is in contact with the barrier strips.

[0017] As an improvement to the above technical solution, the barrier strip includes multiple sets of barrier blocks, and the multiple sets of barrier blocks are evenly arranged on the moving path of the barrier rod.

[0018] The barrier block is provided with a bevel A, and the barrier rod is provided with a bevel B, and the bevel A and bevel B are matched with each other.

[0019] As an improvement to the above technical solution, the feed hopper is provided with a discharge pipe, which is connected to the flange at the feed inlet of the feed screw conveyor.

[0020] The feed hopper is equipped with multiple sets of support rods, which are connected to the support frame of the batching screw conveyor.

[0021] A method for batching ingredients in a brine purification workshop includes the following steps:

[0022] S1. Pipeline connection:

[0023] Connect the discharge port of the batching screw conveyor to the batching barrel, and connect the feed hopper to the feed port of the batching screw conveyor.

[0024] S2, Buffer Test:

[0025] The drive motor drives the drive gear to rotate via a synchronous gear belt, thereby driving a set of rotating rods to rotate. Through the meshing of two sets of sector gears, the two sets of rotating rods rotate simultaneously, causing the two sets of buffer plates to deflect towards the bottom of the feed hopper.

[0026] S3, Ton bag loading:

[0027] After the S2 buffer test is completed, the two sets of buffer plates are reset, and the ton bag is lifted into the feed hopper by other hoisting equipment such as electric hoists, and the ton bag is opened until the material falls onto the two sets of buffer plates.

[0028] S4. Rotary feeding:

[0029] Repeat S2 and the buffer test to slowly increase the gap between the two sets of buffer plates, so that the material falls onto the bottom inner wall of the feed hopper and enters the batching screw conveyor through the discharge pipe, and is then guided into the batching barrel by the batching screw conveyor.

[0030] S5, Rotation Reset:

[0031] After S4 and rotating material feeding are completed, the drive gear is rotated in the opposite direction to reset the two sets of buffer plates. After the reset is completed, repeat S3, ton bag feeding, S4, rotating material feeding, and continue feeding.

[0032] As an improvement to the above technical solution, in S3, ton bag feeding, when the ton bag is unloading, the drive motor drives the drive gear to rotate through the synchronous gear belt, thereby driving a set of rotating rods to rotate. Through the meshing of two sets of sector gears, the two sets of rotating rods rotate simultaneously, causing the two sets of buffer plates to deflect towards the bottom of the feed hopper until there is a gap between the two sets of buffer plates. After the unloading is completed, repeat S4, rotating unloading, and S5, rotating reset.

[0033] Compared with the prior art, the beneficial effects of the present invention are:

[0034] During the batching process, the ton bag is lifted into the feeding hopper, and then the ton bag is fed, so that the material is placed between two sets of buffer plates. Then, the two sets of buffer plates rotate towards the bottom of the feeding hopper, creating a gap between the two sets of buffer plates, which allows the material to slowly fall into the batching screw conveyor, and the batching screw conveyor guides the material into the batching bucket.

[0035] Through the cooperation between the two sets of buffer plates set above, the material can be lifted up during the feeding process of the ton bag, and then the material is slowly dropped into the feeding hopper, thereby avoiding excessive feeding at one time, causing blockage at the outlet of the feeding hopper, and avoiding affecting the original batching efficiency.

[0036] By coordinating the two sets of buffer plates mentioned above, a barrier is formed in the feed hopper during the material feeding process of the ton bag, preventing the material from directly contacting the bottom of the feed hopper and causing mechanical wear on the bottom of the feed hopper, thus effectively improving the service life of the feed hopper.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] Example:

[0050] like Figure 1-10As shown, this embodiment proposes a batching device for a brine purification workshop, including a batching screw conveyor 20, and a batching bucket 10 is provided at the discharge port of the batching screw conveyor 20.

[0051] The feed hopper 30 is provided at the feed inlet of the feed screw conveyor 20. Two sets of buffer plates 40 are provided inside the feed hopper 30. A rotating rod 41 is provided on the buffer plate 40. The rotating rod 41 is rotatably mounted on the feed hopper 30. The buffer plate 40 rotates about the axis of the rotating rod 41 toward the bottom of the feed hopper 30, so that a gap appears between the two sets of buffer plates 40.

[0052] In this embodiment, during the batching process, the ton bag is lifted into the feeding hopper 30, and then the ton bag is unloaded, so that the material is placed between the two sets of buffer plates 40. Then, the two sets of buffer plates 40 rotate towards the bottom of the feeding hopper 30, so that a gap appears between the two sets of buffer plates 40, thereby allowing the material to slowly fall into the batching screw conveyor 20, and the batching screw conveyor 20 guides the material into the batching barrel 10.

[0053] Through the cooperation between the two sets of buffer plates 40 set above, the material can be lifted up during the feeding process of the ton bag, and then the material is slowly dropped into the feeding hopper 30, thereby avoiding excessive feeding at one time, causing blockage at the outlet of the feeding hopper 30, and avoiding affecting the original batching efficiency.

[0054] Through the cooperation between the two sets of buffer plates 40, a barrier can be formed in the feed hopper 30 during the material feeding process of the ton bag, preventing the material from directly contacting the bottom of the feed hopper 30 during the feeding process, thus avoiding mechanical wear on the bottom of the feed hopper 30 and effectively improving the service life of the feed hopper 30.

[0055] Specifically, the feed hopper 30 is symmetrically provided with two sets of support side plates 33, and the support side plates 33 are provided with two sets of rotating holes 34;

[0056] The two ends of the rotating rod 41 are respectively set on the rotating holes 34 corresponding to the positions of the two sets of support side plates 33. The rotating rod 41 rotates in the rotating holes 34, so that the buffer plate 40 rotates about the axis of the rotating rod 41.

[0057] In this embodiment, the cooperation between the rotating rod 41 and the rotating hole 34 facilitates the rotation and offset of the buffer plate 40, which makes it easier to slowly unload the material.

[0058] Specifically, each of the two sets of rotating rods 41 is provided with a sector gear 42, and the two sets of sector gears 42 mesh with each other;

[0059] A set of rotating rods 41 are provided with a drive gear 43, which is fixedly connected to the rotating rods 41 and is connected to an external drive motor through a gear timing belt.

[0060] In this embodiment, when slow feeding is required, the external drive motor drives the drive gear 43 to rotate via a gear synchronous belt, thereby causing a set of rotating rods 41 to rotate, and through the meshing between two sets of sector gears 42, the two sets of buffer plates 40 deflect simultaneously.

[0061] Specifically, the buffer plate 40 is provided with a barrier post 44, and two sets of barrier cavities 45 are symmetrically arranged inside the barrier post 44;

[0062] The barrier cavity 45 is provided with a barrier component 50, which is in contact with the surface of the support side plate 33.

[0063] In this embodiment, friction is generated by the contact between the barrier component 50 and the surface of the support side plate 33, and vibration is generated when the buffer plate 40 deflects, which facilitates the falling off of materials attached to the surface of the feed hopper 30 and the surface of the buffer plate 40.

[0064] Specifically, a barrier ring 46 is provided inside the barrier cavity 45;

[0065] The barrier assembly 50 includes a barrier rod 51, on which a movable rod 52 is provided. The diameter of the movable rod 52 is larger than the diameter of the barrier ring 46, and a spring 53 is provided between the movable rod 52 and the inner wall of the barrier cavity 45.

[0066] Specifically, two sets of barrier strips 32 are provided on the support side plate 33. The barrier strips 32 are symmetrically arranged on the support side plate 33, and the barrier rod 51 is in contact with the barrier strips 32.

[0067] Specifically, the barrier strip 32 includes multiple sets of barrier blocks 322, which are evenly arranged on the moving path of the barrier rod 51.

[0068] The barrier block 322 is provided with a bevel A321, and the barrier rod 51 is provided with a bevel B511. The bevel A321 and the bevel B511 are matched with each other.

[0069] In this embodiment, when the buffer plate 40 deflects, the blocking rod 51 continuously contacts different blocking blocks 322, thereby generating vibration, which facilitates the material adhering to the surface of the feed hopper 30 and the buffer plate 40 to fall off.

[0070] Of course, the contact between the barrier rod 51 and the barrier block 322 can also generate a blocking force, which can prevent the buffer plate 40 from deflecting due to the impact of the material falling when the ton bag is first fed, thus causing the drive gear 43 to rotate and thus avoiding affecting the stability of the gear synchronous belt connection between the drive gear 43 and the drive motor.

[0071] Specifically, the feed hopper 30 is provided with a discharge pipe 31, which is connected to the flange at the feed inlet of the feed screw conveyor 20;

[0072] The feed hopper 30 is provided with multiple sets of support rods 35, and the support rods 35 are connected to the bracket of the feed screw conveyor 20.

[0073] In this embodiment, the material in the feed hopper 30 can be easily introduced into the batching screw conveyor 20 through the discharge pipe 31.

[0074] A method for batching ingredients in a brine purification workshop includes the following steps:

[0075] S1. Pipeline connection:

[0076] The discharge port of the batching screw conveyor 20 is connected to the batching barrel 10, and the feed hopper 30 is connected to the feed port of the batching screw conveyor 20.

[0077] S2, Buffer Test:

[0078] The drive motor drives the drive gear 43 to rotate via the synchronous gear belt, thereby driving a set of rotating rods 41 to rotate. Through the meshing of two sets of sector gears 42, the two sets of rotating rods 41 rotate simultaneously, causing the two sets of buffer plates 40 to deflect toward the bottom of the feed hopper 30.

[0079] S3, Ton bag loading:

[0080] After the S2 buffer test is completed, the two sets of buffer plates 40 are reset, and the ton bag is lifted into the feed hopper 30 by electric hoist or other lifting equipment, and the ton bag is opened until the material falls onto the two sets of buffer plates 40.

[0081] S4. Rotary feeding:

[0082] Repeat S2 and the buffer test to slowly increase the gap between the two sets of buffer plates 40, so that the material falls onto the bottom inner wall of the feed hopper 30 and enters the batching screw conveyor 20 through the discharge pipe 31, and is then guided into the batching barrel 10 by the batching screw conveyor 20.

[0083] S5, Rotation Reset:

[0084] After S4 and rotating material feeding are completed, the drive gear 43 is rotated in the opposite direction, causing the two sets of buffer plates 40 to reset. After the reset is completed, repeat S3, ton bag feeding, S4, rotating material feeding, and continue feeding.

[0085] Specifically, in S3, during the ton bag feeding process, when the ton bag is being unloaded, the drive motor drives the drive gear 43 to rotate via the synchronous gear belt, thereby driving a set of rotating rods 41 to rotate. Through the meshing of two sets of sector gears 42, the two sets of rotating rods 41 rotate simultaneously, causing the two sets of buffer plates 40 to deflect towards the bottom of the feed hopper 30 until there is a gap between the two sets of buffer plates 40. After the unloading is completed, repeat S4, rotating unloading, and S5, rotating reset.

[0086] In this embodiment, the pre-set gap facilitates the flow of materials into the feeding screw conveyor 20 during the feeding process, preventing excessive material accumulation in the feed hopper 30 and thus avoiding material overflow.

[0087] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
