Description
Technical Field
[0001] This utility model relates to the field of brine conveying equipment technology, and in particular to a brine conveying pipeline protection structure and brine conveying system. Background Technology
[0002] In the production of potash mines, brine pipelines, as the core carriers for brine transportation, have long faced challenges due to salt buildup on their inner walls, which has constrained production efficiency. High concentrations of soluble salts in the brine continuously precipitate and adhere to the inner walls of the brine pipelines due to factors such as temperature changes and flow rate fluctuations. This leads to a gradual reduction in the inner diameter of the pipelines and a surge in transportation resistance, directly causing a 30% to 50% decrease in equipment operating load.
[0003] Current solutions rely on a "dissolution + manual salt removal" model: first, fresh water is consumed to dissolve the surface salt deposits, then workers enter the pipeline and use tools such as hammers and steel bars to knock off the salt deposits. A single salt removal process takes 90 to 110 hours. This model not only consumes a large amount of fresh water resources and labor costs, but also poses safety hazards such as pipeline oxygen deficiency and mechanical injury. Furthermore, the salt removal cycle is short (on average, it needs to be done once every 1-2 months), requiring frequent shutdowns to wait for salt removal, which severely reduces brine conduction efficiency.
[0004] Therefore, there is an urgent need for a protective structure and brine conveying system for brine conveying pipelines that can reduce the cost of salt cleaning and improve the efficiency of brine conveying. Utility Model Content
[0005] The purpose of this utility model is to provide a protective structure for brine conveying pipelines and a brine conveying system. By setting a bushing, salt is prevented from directly adhering to the inner wall of the brine conveying pipeline. When salt cleaning is required, a new bushing can be directly replaced to restart the brine conveying process, thereby reducing the cost of salt cleaning and improving the efficiency of brine conveying.
[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a protective structure for a brine conveying pipeline, including: A bushing, the bushing being tubular, is used for installation inside a brine conveying pipeline, the inlet end of the bushing extending to the outside of the inlet end of the brine conveying pipeline, the inlet end of the bushing having a flange, and the outlet end of the bushing extending to the outside of the outlet end of the brine conveying pipeline. And a connector, the connector being used for a sealing connection with the end face of the brine conveying pipe inlet, the connector being connected to the flange for sealing.
[0007] In one embodiment, the connector includes a front pressure plate, a rear pressure plate, and a pressure plate. The front pressure plate is disposed on the inner side of the flange, the rear pressure plate is disposed on the outer side of the flange, and the pressure plate is disposed on the outer side of the rear pressure plate. The pressure plate is used to connect with the end face of the brine conveying pipe inlet, and the pressure plate is used to press the rear pressure plate, the flange, and the front pressure plate tightly against the end face of the brine conveying pipe inlet.
[0008] In one embodiment, the pressure plate includes a pressing part and a supporting part. The pressing part abuts against the side of the rear pressure plate away from the front pressure plate. The supporting part extends radially to the outside of the rear pressure plate and is used to abut against the end face of the brine conveying pipe inlet. The portion of the pressure plate extending to the outside of the rear pressure plate has a first through hole. The pressure plate is connected to the end face of the brine conveying pipe inlet by a connecting bolt disposed in the first through hole.
[0009] As one embodiment, the bolt is a bolt with a locking washer.
[0010] In one embodiment, the pressure plate is provided with a second through hole, and the rear pressure plate and the front pressure plate are both provided with through holes corresponding to the second through hole. The pressure plate is connected to the end face of the brine conveying pipeline inlet by a connecting bolt provided in the second through hole.
[0011] As one embodiment, a sealing gasket is provided between the front pressure plate and the end face of the brine delivery pipe inlet.
[0012] In one embodiment, the rear pressure plate has a protrusion on the side near the front pressure plate, and the front pressure plate has a recess on the side near the rear pressure plate. The protrusion and the recess are shaped to match each other, and the protrusion and the recess are fitted with a gap. The flange is disposed in the gap between the protrusion and the recess.
[0013] In one embodiment, the bushing includes a conveying section and a connecting section. The conveying section is cylindrical, and the connecting section is flared. The small-diameter end of the connecting section is sealed to the conveying section, and the large-diameter end of the connecting section has the flange. The diameter of the connecting section is smaller than the diameter of the brine conveying pipe.
[0014] This utility model also provides a brine delivery system, including: A brine conveying pipeline, wherein the inlet end of the brine conveying pipeline has an end face for installing a bushing; The aforementioned brine conveying pipeline protection structure includes a bushing located inside the brine conveying pipeline, with the inlet end of the bushing extending to the outside of the inlet end of the brine conveying pipeline and the outlet end of the bushing extending to the outside of the outlet end of the brine conveying pipeline. The flange is sealed to the end face of the inlet end of the brine conveying pipeline.
[0015] As one embodiment, the difference between the minimum inner diameter of the bushing and the inner diameter of the brine conveying pipe is 10mm to 16mm.
[0016] The present invention achieves the following technical advantages over the prior art: The brine conveying pipeline protection structure and system disclosed in this utility model guides the brine flow by setting a tubular bushing, avoiding direct contact between the brine and the inner wall of the brine conveying pipeline. This allows the precipitated salt to adhere to the inner wall of the bushing. The bushing is detachably connected to the end face of the inlet end of the brine conveying pipeline. When the salt deposits on the inner wall of the bushing reach a certain amount, the salt deposits in the brine conveying pipeline can be removed by replacing the bushing. This reduces downtime and improves the brine conveying efficiency. Furthermore, no manual entry into the brine conveying pipeline is required for construction, reducing the possibility of risks. The bushing with salt deposits can be directly discarded. Compared to consuming fresh water resources for cleaning and manual peeling, this greatly reduces production costs.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] The purpose of this utility model is to provide a protective structure for brine conveying pipelines and a brine conveying system. By setting a bushing, salt is prevented from directly adhering to the inner wall of the brine conveying pipeline, thereby reducing the cost of salt cleaning and improving the efficiency of brine conveying.
[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] Example 1 Please refer to Figure 1 - Figure 7 This embodiment provides a protective structure for a brine conveying pipeline, including: a bushing 1 and a connector; wherein, the bushing 1 is tubular and is used to install inside the brine conveying pipeline 2, the inlet end of the bushing 1 extends to the outside of the inlet end of the brine conveying pipeline 2, the inlet end of the bushing 1 has a flange 3, the outlet end of the bushing 1 extends to the outside of the outlet end of the brine conveying pipeline 2, and the connector is used to seal and connect with the end face of the inlet end of the brine conveying pipeline 2, and the connector is sealed and connected with the flange 3; its working principle is that, since the connector is sealed and connected with the end face of the inlet end of the brine conveying pipeline 2, and the connector is sealed and connected with the flange 3, when the brine reaches the outside of the inlet end of the brine conveying pipeline 2, it will directly enter the bushing 1, and under the guidance of the bushing 1, flow out from the outlet end of the brine conveying pipeline 2. The brine does not come into contact with the inside of the brine conveying pipeline 2 during the process of passing through the brine conveying pipeline 2. In wall-to-wall contact, the salt precipitated from the brine will not adhere to the inner wall of the brine conveying pipe 2, but will adhere to the inner wall of the bushing 1. The bushing 1 is detachably connected to the end face of the inlet end of the brine conveying pipe 2. When the salt deposits on the inner wall of the bushing 1 reach a certain amount, the connector can be removed from the end face of the inlet end of the brine conveying pipe 2. The bushing 1 can then be removed from the brine conveying pipe 2 by applying external force and replaced with a new brine conveying pipe 2. This process of replacing the bushing 1 is much faster than manually cleaning the salt deposits inside the brine conveying pipe 2, greatly reducing downtime and improving brine conveying efficiency. Furthermore, no manual entry into the brine conveying pipe 2 is required for construction, reducing the possibility of risks. The bushing 1 with salt deposits can be directly discarded. Compared to consuming fresh water resources for cleaning and manual stripping, this method greatly reduces production costs.
[0024] In one embodiment, the bushing 1 has a certain degree of flexibility, and salt deposits can be removed by tapping the outer wall of the bushing 1. Compared with the method of removing salt deposits directly in the brine pipeline 2, it also has the advantages of low cost and high safety.
[0025] It is understandable that the end face of the inlet end of the brine conveying pipe 2 refers to the structural surface on the radially outer side of the inlet end of the brine conveying pipe 2. This structural surface can be a wall surface, that is, the brine conveying pipe 2 is opened on the wall surface, and the wall surface on the radially outer side of the brine conveying pipe 2 is the end face of the inlet end of the brine conveying pipe 2. It can also be a connection structure such as a flange installed on the wall surface.
[0026] In one embodiment, when removing the bushing 1 with attached salt deposits from the brine conveying pipe 2, the outlet end and / or inlet end of the bushing 1 are first sealed, and then an external force is applied to pull the bushing 1 out, so as to prevent the salt deposits that are dislodged due to vibration from falling into the brine conveying pipe 2 during the removal of the bushing 1.
[0027] In one embodiment, the connector includes a front pressure plate 4, a rear pressure plate 5, and a pressure plate. The front pressure plate 4 is disposed on the inner side of the flange 3, the rear pressure plate 5 is disposed on the outer side of the flange 3, and the pressure plate is disposed on the outer side of the rear pressure plate 5. The pressure plate is used to connect with the end face of the inlet end of the brine conveying pipe 2 and to press the rear pressure plate 5, the flange 3, and the front pressure plate 4 tightly onto the end face of the inlet end of the brine conveying pipe 2. It can be understood that the inner side of the flange 3 refers to the side of the flange 3 close to the end face of the inlet end of the brine conveying pipe 2, and the outer side of the flange 3 refers to the side of the flange 3 away from the end face of the inlet end of the brine conveying pipe 2. After the pressure plate is connected to the end face of the inlet end of the brine conveying pipe 2, it can provide the rear pressure plate 5 with a pressing force toward the end face of the inlet end of the brine conveying pipe 2. This pressing force can press and fix the rear pressure plate 5, the flange 3, and the front pressure plate 4 tightly onto the end face of the inlet end of the brine conveying pipe 2, thereby realizing the installation of the bushing 1.
[0028] In one embodiment, the pressure plate includes a pressing part 6 and a supporting part 7. The pressing part 6 abuts against the side of the rear pressure plate 5 away from the front pressure plate 4. The supporting part 7 extends radially to the outside of the rear pressure plate 5 and is used to abut against the end face of the inlet end of the brine conveying pipe 2. A part of the pressing part 6 also extends radially to the outside of the rear pressure plate 5. The portion of the pressure plate extending to the outside of the rear pressure plate 5 is provided with a first through hole 8. The pressure plate is connected to the end face of the inlet end of the brine conveying pipe 2 by a connecting bolt provided in the first through hole 8. The end face of the inlet end of the brine conveying pipe 2 is provided with a threaded hole that matches the connecting bolt. The pressure plate can be fixed to the end face of the inlet end of the brine conveying pipe 2 by the connecting bolt. The pressure plate then presses the rear pressure plate 5, the flange 3, and the front pressure plate 4 together. This method eliminates the need for openings on the front pressure plate 4 and the rear pressure plate 5, ensuring the overall structural strength of the front pressure plate 4 and the rear pressure plate 5.
[0029] In one embodiment, bolts with anti-loosening washers are used, which improves the stability of bushing 1 installation.
[0030] Preferably, the connecting bolts are quick-connect bolts.
[0031] In one embodiment, a second through hole 9 is provided on the pressure plate, and both the rear pressure plate 5 and the front pressure plate 4 are provided with through holes corresponding to the second through hole 9. The pressure plate is connected to the end face of the brine conveying pipe 2 through connecting bolts provided in the second through hole 9. The bolts pass through the second through hole 9, the through hole on the rear pressure plate 5 and the through hole on the front pressure plate 4 in sequence. This connection method can directly apply the force of the connecting bolts to the rear pressure plate, so that the rear pressure plate can provide greater extrusion force for the flange 3 to ensure the installation stability of the bushing 1. The through holes are not shown in the figure.
[0032] In one embodiment, a sealing gasket is provided between the pressure plate and the rear pressure plate 5 to prevent brine from entering the brine conveying pipe 2 through the second through hole 9 and the through hole.
[0033] Preferably, the flange 3 is located on the side of the through hole close to the axis of the front pressure plate 4 and the rear pressure plate 5, which avoids damage to the bushing 1 and the problem of reduced structural strength of the bushing 1.
[0034] In one embodiment, a sealing gasket is provided between the front pressure plate 4 and the end face of the brine conveying pipe 2 inlet. By providing the sealing gasket, the airtightness of the connection between the front pressure plate 4 and the end face of the brine conveying pipe 2 inlet can be improved, thereby reducing the amount of brine entering the brine conveying pipe 2 from between the end face of the front pressure plate 4 and the end face of the brine conveying pipe 2 inlet.
[0035] In one embodiment, a protrusion 10 is provided on the side of the rear pressure plate 5 near the front pressure plate 4, and a recess 11 is provided on the side of the front pressure plate 4 near the rear pressure plate 5. The protrusion 10 and the recess 11 are matched in shape and are fitted with a clearance. The flange 3 is provided in the gap between the protrusion 10 and the recess 11. This method can greatly improve the clamping force of the front pressure plate 4 and the rear pressure plate 5 on the flange 3, thereby improving the stability of the bushing 1 during use.
[0036] In one embodiment, the bushing 1 includes a conveying section 12 and a connecting section 13. The conveying section 12 is cylindrical, and the connecting section 13 is trumpet-shaped. The small-diameter end of the connecting section 13 is sealed to the conveying section 12, and the large-diameter end of the connecting section 13 has a flange 3. The diameter of the connecting section 13 is smaller than the diameter of the brine conveying pipe 2. By setting the trumpet-shaped connecting section 13, the stable installation of the bushing 1 is ensured. When brine enters the bushing 1, it can expand the bushing 1 radially. Setting the diameter of the connecting section 13 to be smaller than the diameter of the brine conveying pipe 2 provides sufficient space for the bushing 1 to expand. This avoids the problem of wrinkles or overlap of the part of the bushing 1 located inside the brine conveying pipe 2. It is understood that the gaps caused by the wrinkles and overlap of the bushing 1 are more likely to adhere to salt. This method can effectively avoid the above problems, reduce the speed of salt adhesion, and extend the salt cleaning cycle.
[0037] Example 2 Please refer to Figure 1 - Figure 7 This embodiment provides a brine conveying system, including a brine conveying pipe 2 and the aforementioned brine conveying pipe protection structure. The inlet end of the brine conveying pipe 2 has an end face for installing a bushing 1. The bushing 1 is located inside the brine conveying pipe 2. The inlet end of the bushing 1 extends to the outside of the inlet end of the brine conveying pipe 2, and the outlet end of the bushing 1 extends to the outside of the outlet end of the brine conveying pipe 2. The inlet end of the bushing 1 has a flange 3, which is sealed to the end face of the inlet end of the brine conveying pipe 2 by a connector. During use, the brine will not enter the interior of the brine conveying pipe 2, but will pass through the internal space of the bushing 1 and then through the brine conveying pipe 2. This not only completes the flow of brine but also prevents salt precipitation in the brine. The salt deposits are directly attached to the inner wall of the brine conveying pipe 2. When the salt deposits on the inner wall of the bushing 1 reach a certain amount, the connector can be removed from the end face of the inlet of the brine conveying pipe 2. By applying external force to the bushing 1, the bushing 1 with salt deposits can be removed from the brine conveying pipe 2. Then, the new bushing 1 can be installed into the brine conveying pipe 2, and the brine conveying operation can be restarted. The process of replacing the bushing 1 is much shorter than the process of cleaning the salt deposits on the inner wall of the brine conveying pipe 2 bit by bit, which greatly reduces the downtime waiting time, improves the brine conveying efficiency, eliminates the need for manual entry into the brine conveying pipe 2 for construction, reduces potential risks, and eliminates the need for large amounts of clean water for desalination, reducing energy consumption and production costs.
[0038] In one embodiment, the difference between the minimum inner diameter of the bushing 1 and the inner diameter of the brine conveying pipe 2 is 10mm to 16mm. Specifically, the inner diameter of the conveying section 12 is the minimum inner diameter of the bushing 1, and the difference between the inner diameter of the conveying section 12 and the inner diameter of the brine conveying pipe 2 is 10mm to 16mm.
[0039] In one embodiment, the bushing 1 is made of scraped cloth. According to the inner diameter of the brine conveying pipe 2, the scraped cloth is cut into a specific size and shape, rolled into a tube, and the overlapping parts are sealed together by hot melt welding to obtain the bushing 1.
[0040] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
