Description

Technical Field

[0001] The present invention relates to the field of salt collection and processing, and specifically relates to a salt collection device based on edible salt. Background Art

[0002] In China, well salt is the main source of edible salt. According to relevant data, among the raw materials of edible salt in China, well salt accounts for the largest proportion, about 61%. From the perspective of the salt product structure, the proportion of well salt is even as high as 87%, far exceeding sea salt.

[0003] Well salt has the advantages of simple mining and processing, low cost, high purity, few impurities, excellent quality, and rich resources. Moreover, as one of the important raw materials in the chemical industry, it can be used to produce chemicals such as chlor-alkali, soda ash, and calcium chloride, can also be used as a deicing agent in industrial deicing work, and can also be used as edible salt after adding nutritional fortifiers and other treatments. Therefore, well salt plays a crucial role in Chinese edible salt.

[0004] The preparation of well salt is carried out by professional drilling equipment to drill a mine in the salt ore layer deep underground, then inject fresh water into the salt mine to dissolve the salt ore in the water to form brine, and then use a pump to extract the brine dissolved with salt from the mine and transport it through a pipeline to the multi-level salt pans on the ground. Through the evaporation method, salt crystals precipitate in the salt pans to form crude well salt products.

[0005] The well salt crystals in the salt pans mainly precipitate through the evaporation method. After evaporation, the precipitated salt crystals form salt lumps of various shapes and sizes and are mixed with impurities. The conventional collection method is to use a salt harvester to collect. The salt harvester shovels, lifts, and throws the raw salt onto the salt conveying equipment while walking in the salt pans. The salt materials collected by this equipment contain some mother materials and impurities. Therefore, it is necessary to use a variety of equipment to screen, separate, and dry to further purify. This process has complicated steps, requires the cooperation of a variety of equipment, consumes a large amount of energy, and has low preparation efficiency.

Detailed implementation mode

[0033] Next, in combination with the attached Figure 1-10 A specific embodiment of the present invention will be elaborated in detail.

[0034] Refer to the attached Figure 1 , a salt collection device based on salt, including a frame 1 with universal wheels installed at the bottom. A collection mechanism, a separation mechanism and a filling mechanism for collecting the precipitated salt crystals in the salt pan pond are provided on the frame 1. According to the description in the background technology, the brine dissolved with salt is commonly called mother liquor and needs to flow through multiple salt pan ponds. The main purpose of setting multiple salt pan ponds is to improve the purity and production efficiency of salt, and at the same time make full use of natural resources such as sunlight and wind energy. The design of multiple salt pan ponds enables the brine to be gradually concentrated in different ponds and finally crystallized into salt in the lowest-level salt pan pond. During this process, the crystals (hereinafter collectively referred to as: salt materials) are stratified from the mother liquor, the salt materials are deposited at the bottom of the pond, and the mother liquor is static on it. When the thickness of the salt materials reaches five to fifteen centimeters (adjusted according to process requirements), the collection can start.

[0035] Refer to the attached Figure 1-2 , to facilitate the collection of the salt materials at the bottom of the salt pan pond, this device is realized by setting a bucket 3 on the frame 1. A bucket 3 made of stainless steel is fixedly connected to the frame 1. This material is not easily corroded and deformed and can be used for a long time. A conveyor belt 2 for transporting the salt materials collected by the bucket 3 is provided on the frame 1. The bottom of the conveyor belt 2 is connected to the top of the bucket 3, aiming to push the salt materials shoveled by the bucket 3 onto the conveyor belt 2 as the frame 1 moves.

[0036] Since the salt material collected on the bucket 3 necessarily contains a part of mother liquor, and the ultimate goal of this device is to obtain the crude product of the salt material, it is necessary to separate the salt material from the mother liquor. The following technical solution is adopted in this embodiment: The conveyor belt 2 is provided with evenly distributed water filtering holes. During the process of the salt material being conveyed on the conveyor belt 2, the mother liquor can naturally flow out through the water filtering holes.

[0037] Refer to the appendix Figure 3 , a receiving hopper 4 for collecting the salt material on the conveyor belt 2 is fixedly connected to the vehicle frame 1. The top of the receiving hopper 4 is open, and the opening is lower than the end of the conveyor belt 2, aiming to enable the salt material to fall into the receiving hopper 4 after being directionally transported by the conveyor belt 2. There is a possibility that the bottom layer of salt material in contact with the conveyor belt 2 adheres to the conveyor belt 2. To completely collect the salt material, the following technical solution is adopted in this embodiment: A scraper 5 that fits the conveying terminal of the conveyor belt 2 is fixedly connected to the vehicle frame 1. The scraper 5 is suspended above the top opening of the receiving hopper 4. The salt material conveyed on the conveyor belt 2 and the salt material adhering to the conveyor belt 2 can be scraped off by the scraper 5 and fall into the receiving hopper 4, avoiding excessive salt material adhering to the conveyor belt 2 and blocking the water filtering holes, which affects the subsequent separation of the mother liquor from the salt material, and at the same time reducing the waste of the salt material.

[0038] Refer to the appendix Figure 3-5 , as described in the background technology, the salt material precipitated in the salt pan pool forms salt lumps of different sizes due to factors such as high temperature or wind, which accelerate the evaporation of water. The salt lumps are shoveled up by the bucket 3 and transported to the receiving hopper 4 through the conveyor belt 2. To facilitate subsequent collection and preparation, the salt material needs to be broken up. Therefore, this device realizes it by setting a breaking-up assembly. The breaking-up assembly is arranged on the receiving hopper 4. A discharging port 401 is opened on the right side of the receiving hopper 4. A first spiral shaft 6 is rotatably connected in the receiving hopper 4. First spiral blades 7 are arranged on the first spiral shaft 6, aiming to drive the first spiral blades 7 to rotate by the rotation of the first spiral shaft 6, and then unidirectionally push the salt material falling into the receiving hopper 4 towards the discharging port 401. During the pushing process, the first spiral blades 7 can stir and break up the salt material. A power source for driving the first spiral shaft 6 to rotate is arranged on the side wall of the receiving hopper 4, and the first spiral shaft 6 can be driven to rotate through the power source.

[0039] Generally, there is still mother liquor remaining in the broken-up salt material. Conventionally, a separate drying device can be used to further purify it, remove the excess mother liquor and moisture, and obtain a purer salt material. However, the drying device consumes a large amount of energy, has high professionalism requirements, and at the same time, waste gas and waste water will be generated during the drying process, which has a certain impact on the environment and the lives of surrounding residents. Considering the above, this device abandons this purification method and instead adopts a centrifugal method. The collection device working in the salt pan pool can perform centrifugal operation on the collected salt material to remove the mother liquor contained on the surface and in the gaps of the salt material, reduce the initial humidity of the salt material, maintain the uniformity of the salt material particles, reduce the subsequent drying difficulty, and at the same time, return the separated mother liquor to the salt pan pool.

[0040] A centrifugal component is provided on the vehicle frame 1. The outer cylinder 8 fixed to the vehicle frame 1 is controlled. A coaxial inner cylinder 9 is arranged inside the outer cylinder 8, and the outer cylinder 8 and the inner cylinder 9 form a double-cylinder structure. The inner cylinder 9 serves as a centrifugal cylinder, and water passing holes are densely arranged thereon. One end of the inner cylinder 9 penetrates to the outside of the outer cylinder 8 to connect a rotational power source. The inner cylinder 9 rotates at a high speed under the drive of the rotational power source. A sealing ring 10 is arranged between the outer cylinder 8 and the inner cylinder 9. A reflux cavity 801 is formed among the outer cylinder 8, the inner cylinder 9, and the sealing ring 10. The high-speed rotating inner cylinder 9 can, through centrifugal action, throw the mother liquor from the water passing holes of the inner cylinder 9 into the reflux cavity 801, while the salt material remains in the inner cylinder 9, achieving the effect of separating the mother liquor and the salt material.

[0041] A second spiral shaft 11 is arranged inside the inner cylinder 9. A second spiral blade 12 is connected to the second spiral shaft 11. One end of the second spiral shaft 11 penetrates to the outside of the end of the inner cylinder 9. The second spiral shaft 11 is controlled to rotate and drives the connected second spiral blade 12 to rotate. An outlet 901 is arranged at the end of the inner cylinder 9. The outlet 901 and the reflux cavity 801 are separated by the sealing ring 10. A feed cavity 111 is arranged inside the second spiral shaft 11. A feed pipe 13 is arranged inside the feed cavity 111. The feed pipe 13 is communicated with the discharge port 401 of the feed hopper 4. An outflow port 112 is arranged on the second spiral shaft 11. The feed cavity 111 of the second spiral shaft is communicated with the inner cavity of the inner cylinder 9 through the outflow port 112.

[0042] The salt material in the feed hopper 4 enters the inner cavity of the second spiral shaft 11 through the feed pipe 13. After being dispersed, the salt material will enter the inner cavity of the inner cylinder 9 through the outflow port 112. The inner cylinder 9 rotates at a high speed, and the second spiral shaft 11 rotates slowly. The high-speed rotating inner cylinder 9 throws the mother liquor into the reflux cavity 801, and the salt material is pushed towards the outlet 901 by the second spiral blade 12.

[0043] Reference appendix Figure 6 For realizing the centrifugal action, it is necessary to use multiple power sources to drive the second spiral shaft 11 and the inner cylinder 9 to perform rotational actions at different speeds respectively. The rotational speed of the second spiral shaft 11 is less than that of the inner cylinder 9. Conventionally, independent power sources can be set separately for the second spiral shaft 11 and the inner cylinder 9 to achieve this. However, in this embodiment, to reduce costs, the following technical solution is adopted by this device: A first transmission wheel 14 is key-connected to the end of the inner cylinder 9. One end of the second spiral shaft 11 that penetrates to the outside of the end of the inner cylinder 9 is key-connected to a second transmission wheel 15. A first motor 16 and a second motor 17 are installed on the vehicle frame 1. The output shaft of the first motor 16 is connected to the first transmission wheel 14 through a first conveyor belt 18. The output shaft of the second motor 17 is connected to the second transmission wheel 15 through a second conveyor belt 19. It can be known that the output rotational speed of the second motor 17 is greater than that of the first motor 16.

[0044] In this embodiment, the rotational speeds of the first spiral shaft 6 and the second spiral shaft 11 are close to each other and are both slow rotations. Based on this, without separately setting a power source, the externally placed end of the first spiral shaft 6 is key-connected with a first gear 20. A rotating shaft 21 is rotatably provided on the outer wall of the discharge hopper 4. A second gear 22 and a third transmission wheel 23 are key-connected to the rotating shaft 21. The first gear 20 meshes with the second gear 22. One end of the second spiral shaft 11 that penetrates to the outside of the end of the inner cylinder 9 is also key-connected with a fourth transmission wheel 24. The third transmission wheel 23 and the fourth transmission wheel 24 are connected by a third conveyor belt 25.

[0045] Driven by the power source output by the first motor 16 and through the transmissions of the first conveyor belt 18 and the third conveyor belt 25, the first spiral shaft 6 and the second spiral shaft 11 are respectively driven to rotate. Thus, only through the output of the first motor 16, the synchronous rotation of the first spiral shaft 6 of the dispersing assembly and the second spiral shaft 11 in the centrifugal assembly can be achieved. The first gear 20 and the second gear 22 mesh to form a speed-changing gear set, so that there is a better rotational speed difference between the first spiral shaft 6 and the second spiral shaft 11 according to the actual working conditions, and the salt material is pushed in opposite directions.

[0046] Refer to the appendix Figure 3-5 , the ends of the outer cylinder 8, the inner cylinder 9 and the sealing ring 10 form a material falling cavity 802. A material falling port 803 is provided at the bottom of the outer cylinder 8. The material falling port 803 and the discharge port 901 are both communicated with the material falling cavity 802. A discharge hopper 26 for collecting salt material is fixedly connected at the material falling port 803. The salt material obtained by centrifugal separation enters the material falling cavity 802 through the discharge port 901 and falls into the discharge hopper 26 through the material falling port 803 to be collected.

[0047] The mother liquor obtained by centrifugal separation is a saturated solution separated during the crystallization process and can be recycled as a resource. Therefore, this device realizes the recycling of the mother liquor by setting a mother liquor circulation assembly and returns the mother liquor to the salt pan pond. The mother liquor circulation assembly is arranged on the vehicle frame 1 and includes a water collecting box 27 provided at the bottom of the vehicle frame 1 for collecting the mother liquor. The water collecting box 27 is communicated with the return cavity 801 of the outer cylinder 8. The mother liquor that enters the return cavity 801 after centrifugation flows downward by gravity into the water collecting box 27 to be collected.

[0048] Refer to the appendix Figure 2 , there are often sundries on the surface of the salt material shoveled by the bucket 3. In this embodiment, considering that the separated mother liquor needs to flow back into the salt pan pond, the sundries are removed by guiding the mother liquor to wash the salt material on the conveyor belt 2. Specifically, a spray pipe 28 connected to the vehicle frame 1 is provided above the conveyor belt 2. The spray pipe 28 is connected to the water collecting box 27 through a delivery pipe. A pump is connected to the delivery pipe. A plurality of nozzles 29 are installed on the spray pipe 28.

[0049] Starting the pump can transport the mother liquor in the water collecting box 27 to the nozzle 28 and spray it out through the nozzle 29. The purpose is, firstly, to use the saturated solution of the mother liquor to spray and flush the debris on the agglomerated salt material transmitted on the conveyor belt 2 without causing the salt material to dissolve; secondly, the mother liquor will flow back to the salt pan pool and can be continuously recovered in the subsequent salt drying, thereby improving the utilization rate of the mother liquor and reducing the energy consumption of subsequent salt drying.

[0050] Reference Figure 1 and Figure 5 After the above work is completed, the salt collected in the discharge hopper 26 needs to be transported and carried out to the next process. In order to facilitate the subsequent processing and transportation of the salt, the device automatically fills the salt in the discharge hopper 26 by arranging a storage tank 30 on the frame 1. A support frame 31 is fixedly connected to the frame 1, and the support frame 31 is used to carry filling-related components. A plurality of storage tanks 30 for holding salt are arranged on the support frame 31, and the storage tank 30 is a cylinder with an opening on the top.

[0051] Reference Figure 5 Considering that the discharge hopper 26 is located at the bottom of the frame 1, in order to complete the filling action, the salt material in the discharge hopper 26 needs to be transported from bottom to top to the opening at the top of the storage tank 30, so the present device is realized by setting a lifting assembly. The lifting assembly includes a lifting pipe 32 fixedly connected to the support frame 31 for lifting the salt material in the discharge hopper 26 to the filling height, the lifting pipe 32 is hollow and has a lifting screw 33 connected thereto, and a third motor 34 is also provided at the top of the lifting pipe 32 to drive the lifting screw 33 to rotate, and the output shaft of the third motor 34 is fixedly connected to the lifting screw 33 through a coupling, aiming to lift the salt material from bottom to top through the rotation of the lifting screw 33, and a side wall at the top of the lifting pipe 32 is connected to a discharge pipe 35, and the discharge pipe 35 extends to the opening at the top of the storage tank 30.

[0052] The salt in the discharge hopper 26 falls into the bottom of the lifting tube 32. By starting the third motor 34 to drive the lifting screw 33 to rotate, the salt at the bottom of the lifting tube 32 is transported upward from bottom to top to the top of the lifting tube 32, and then falls into the storage tank 30 through the discharge pipe 35, thereby realizing the filling operation. In this embodiment, the salt is continuously delivered from the discharge pipe 35. Considering that a plurality of storage tanks 30 are provided on the support frame 31, the filling action of the device can fill the storage tanks 30 one by one. Therefore, in order to realize continuous filling, the discharge pipe 35 is made of a retractable flexible material, and the pipe can be stretched and contracted manually, thereby realizing the effect of facilitating the filling of the storage tanks 30 one by one.

[0053] Furthermore, to prevent the salt material filled in the storage tank 30 from spilling during transportation, a tank cover 38 for sealing is rotatably connected to the top of the storage tank 30. The tank cover 38 can be opened and closed by rotation. Before the filling operation starts, rotate the tank cover 38 to open it, insert the discharge pipe 35 into the opening at the top of the storage tank 30. After the filling operation is completed, rotate the tank cover 38 to close it, thereby sealing the salt material in the storage tank 30 and preventing the salt material from spilling during the transportation of the storage tank 30.

[0054] Refer to the attached Figure 5-9 After the filling of the storage tank 30 is completed, it needs to be transported to the next process. To facilitate the transportation of the storage tank 30, therefore, a first sliding frame 36 and a second sliding frame 37 are fixedly connected to the support frame 31. Symmetrically distributed handles are fixedly connected to the side wall of the storage tank 30, and the handles are both placed in contact with the first sliding frame 36 and the second sliding frame 37. Setting the handles is for the convenience of the subsequent handling by the staff, and secondly, the handles can slide on the first sliding frame 36 and the second sliding frame 37. Through the fitting contact between the handles and the first sliding frame 36 and the second sliding frame 37, the support frame 31 can play a certain supporting role for the storage tank 30. Uniformly distributed rollers 39 are also provided at the bottom of the support frame 31, and the storage tank 30 is carried on the rollers 39, aiming to reduce the friction generated by the movement of the storage tank 30 and facilitate the directional movement of the storage tank 30.

[0055] A rotating member 40 is rotatably connected to the second sliding frame 37. The rotating member 40 can be rotated to open, aiming to form a gate that can be flexibly opened and closed. After the rotating member 40 is rotated to open, the storage tank 30 can be transported out of the support frame 31. A pin hole is opened on the rotating member 40, and a first pin 41 is clamped in the pin hole. An ear 42 is provided on the support frame 31, and the ear 42 can be clamped with the first pin 41, aiming to fix the first pin 41 on the support frame 31 through the clamping of the first pin 41 and the ear 42 on the support frame 31, aiming to form a closed gate and lock the storage tank 30 on the support frame 31. According to the above, when the storage tank 30 is filled, the handle can be pushed. Under the action of the first sliding frame 36, the second sliding frame 37 and the rollers 39, the storage tank 30 can smoothly move to the side close to the rotating member 40. At this time, cancel the clamping of the first pin 41 and the ear on the support frame 31, and the rotating member 40 is rotated to open, and the storage tank 30 can be removed from the support frame 31.

[0056] The storage tank 30 is placed on the rollers of the support frame 31, and multiple storage tanks 30 are filled one by one. After the storage tank 30 is filled, it is pushed out of the vehicle frame. The subsequent empty storage tanks 30 move closer to the lifting pipe 32. With the vibration of the vehicle frame, there may be a situation where the storage tank 30 accidentally topples over during filling. Therefore, the device is provided with a fixing component for fixing the storage tank 30 on the support frame 31, including a plurality of clamping seats 43 opened on the second sliding frame 37. A limiting frame 44 is slidably connected between the first sliding frame 36 and the second sliding frame 37. The limiting frame 44 can slide on the first sliding frame 36 and the second sliding frame 37. A second locking pin 45 is slidably arranged at one end of the limiting frame 44. The second locking pin 45 can be clamped with the clamping seat 43 on the second sliding frame 37, aiming to move the limiting frame 44 to fit against the outer wall of the outermost storage tank 30. Through the clamping of the second locking pin 45 with the clamping seat 43, the effect of stabilizing the storage tank 30 on the support frame 31 can be achieved. In addition, after the front storage tank 30 breaks away from the support frame 31, the subsequent storage tanks 30 can be pushed forward. At this time, the limiting frame 44 can be moved forward synchronously. Through the clamping of the second locking pin 45 on the limiting frame 44 with the clamping seat 43 on the adjacent second sliding frame 37, the effect of fixing the subsequent storage tanks 30 to be transported can be achieved.

[0057] Reference appendix Figure 10 In a natural state, the salt pan pond will accelerate the evaporation of surface water due to strong winds, causing the surface of the salt pan layer to quickly harden and form a hard crust. Long-term accumulation will cause the salt grains in the salt pan pond to be pressed and agglomerated. When collecting with the bucket 3, the agglomerated salt layer will cause a certain degree of damage to the bucket 3, thereby affecting the collection operation. Therefore, the device is improved as follows. A mortise 301 is opened at the end of the bucket 3, and a detachable shoveling component is arranged in the mortise 301, including a connecting frame 46 in the mortise 301. The connecting frame 46 can be laterally installed into the mortise 301 from the side of the mortise 301 on the bucket 3. A plurality of telescopic members 47 are fixedly connected to the connecting frame 46. An L-shaped limiting member 48 is fixedly connected to the bucket 3. When the bucket 3 is installed, it is also installed laterally from the mortise 301. The function of the L-shaped limiting member 48 is to prevent the bucket 3 from dislocating from the mortise 301. A spring 49 is sleeved outside the telescopic member 47, and the spring 49 is compressed between the limiting member 48 and the connecting frame 46.

[0058] Through the movement of the vehicle frame 1, the bucket 3 can shovel and collect the salt material in the salt pan pond. When the bucket 3 collides with a hard object at the bottom of the salt pan pond, a squeezing force will be generated, causing the limiting member 48 to retreat backward and upward for a certain distance to avoid the hard object. At this time, the output end of the telescopic member 47 contracts, and the spring 49 deforms. Under the action of the spring 49, the squeezing force received by the limiting member 48 can be counteracted, thereby realizing the protection of the limiting member 48.

[0059] Since the main component of the salt layer in the salt pan is sodium chloride, this component will cause certain corrosive damage to the material shoveling assembly. Therefore, the bucket 3, the limiting member 48, the connecting frame 46, and the spring 49 of this device are all made of stainless steel or epoxy-coated carbon steel, aiming to reduce the corrosive damage of the salt layer to this material shoveling assembly, thereby extending the service life of this equipment.

[0060] Because the material shoveling assembly is detachably installed in the mortise groove of the bucket 3, in order to ensure that the bucket 3 can be stable in the mortise groove 301 and does not slide out laterally when the vehicle frame 1 operates, the following technical solution is adopted: the connecting frame 46 is concave, and a fixed rotating plate 50 is rotatably connected to the side wall of the connecting frame 46. After the connecting frame 46 is pushed into and installed from the opening of the mortise groove 301 on the side of the bucket 3, the fixed rotating plate 50 can be fixed on the vehicle frame 1 by means of fasteners. At the same time, the side wall of the concave connecting frame 46 also plays a sealing role for the mortise groove 301.

For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
