Description

Technical Field

[0001] This utility model relates to the field of corrosion-resistant salt dehydration technology, specifically to a corrosion-resistant salt dehydration device. Background Technology

[0002] Chemical enterprises generate large amounts of inorganic salts and heavy metal mixtures during production. The waste salt contains a large number of organic or inorganic impurities. Over a long period of time, or through its own changes, it gradually forms a type of corrosion-resistant mixed salt, which can easily cause serious pollution and damage to the ecological environment. Therefore, it is necessary to centrally treat the corrosion-resistant mixed salt. The existing treatment process for corrosion-resistant mixed salt requires centrifugal separation of crystalline salt and wastewater.

[0003] In the dehydration device for corrosion-resistant mixed salts, the main method is to separate the crystalline salt and wastewater by centrifuging the centrifuge. The wastewater passes through the centrifuge and is discharged, while the crystalline salt can be collected and discharged from the top of the centrifuge. However, in existing devices, the separation of crystalline salt and wastewater is often accomplished solely by the active rotation of the centrifuge, lacking the necessary stirring structure. Furthermore, the interior of the long-accumulated corrosion-resistant mixed salts is relatively compact, and simple centrifugation cannot break the tight bond between them. This means that the wastewater inside cannot be discharged in time, resulting in a low overall centrifugal dehydration efficiency.

[0004] Therefore, it is necessary to invent a corrosion-resistant dehydration device for mixed salts to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a corrosion-resistant salt dehydration device. This device solves the problem that existing technologies rely solely on the active rotation of a centrifuge drum to separate crystalline salt and wastewater, lacking the necessary stirring structure. Furthermore, the internal structure of long-term accumulated corrosion-resistant salt is quite compact, and simple centrifugal separation cannot break this tight bond, preventing timely centrifugal discharge of the internal wastewater and ultimately resulting in low overall centrifugal dehydration efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A corrosion-resistant salt dehydration device includes a U-shaped frame, a centrifuge cylinder rotatably mounted above the bottom of the U-shaped frame for centrifugal dehydration of corrosion-resistant salts, and a cylinder cover longitudinally slidably mounted below the top of the U-shaped frame, which can close or open the top of the centrifuge cylinder. A ring-shaped water receiving seat is detachably installed in the middle of the U-shaped frame, with its inner circumferential sidewall slidingly abutting against the outer circumferential sidewall of the centrifuge cylinder. A first telescopic member is detachably installed in the middle of the cylinder cover, with a pressure plate installed at the bottom end of the first telescopic member. Multiple uprights are installed at the bottom inside the cylinder cover, and multiple crossbars are installed on the circumferential sidewall of each upright. A sloping platform ring plate is installed between the bottom ends of the multiple uprights.

[0008] In a preferred embodiment of this utility model, the diameter of the pressure plate is the same as the inner diameter of the centrifuge cylinder, and the diameter of the inclined platform ring plate is the same as the inner diameter of the centrifuge cylinder.

[0009] As a preferred embodiment of this utility model, a plurality of feed pipes for conveying corrosion-resistant salts to be dehydrated into the centrifuge cylinder are installed on the top side of the peripheral wall of the centrifuge cylinder, and a plurality of water outlet holes are opened on the peripheral wall of the centrifuge cylinder, and the contact position between the annular water receiving seat and the centrifuge cylinder is located below the water outlet holes.

[0010] When the cap closes the top of the centrifuge cylinder, the contact position between the pressure plate and the centrifuge cylinder is lower than the water outlet hole.

[0011] As a preferred embodiment of this utility model, the cylinder cover has a through hole in the middle, and a protective cylinder is detachably installed in the through hole. The first telescopic member is detachably installed in the protective cylinder, and the pressure plate is provided with a through groove for the vertical pole and the horizontal bar to pass through longitudinally at each pole.

[0012] As a preferred embodiment of this utility model, a driving component is detachably installed above the bottom of the U-shaped frame, and a card holder is detachably installed at the output end of the driving component, and the centrifuge cylinder is detachably snapped into the card holder.

[0013] As a preferred embodiment of this utility model, a second telescopic component can be detachably installed at symmetrical positions below the top of the U-shaped support frame, and the bottom ends of multiple second telescopic components are detachably connected to the top of the cylinder cover.

[0014] As a preferred embodiment of this utility model, a side support frame is detachably installed in the middle of the U-shaped support frame, the annular water receiving seat is detachably snapped into the side support frame, and a drain pipe is installed at the bottom of the annular water receiving seat.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] In this invention, the centrifuge drum actively rotates to centrifuge and separate the corrosion-resistant salts inside. During the rotation of the centrifuge drum, the first telescopic component can drive the pressure plate to move longitudinally inside the centrifuge drum, thereby squeezing the corrosion-resistant salts inside and breaking the tight bond between them. Furthermore, during the rotation, the corrosion-resistant salts inside the centrifuge drum are continuously stirred under the action of multiple uprights and crossbars. Through the continuous squeezing of the pressure plate and the continuous stirring of the uprights and crossbars, the tight bond between the corrosion-resistant salts is quickly and efficiently broken, allowing the wastewater inside to break through the salt's restriction during centrifugation and be discharged from the centrifuge drum in a timely manner, thus improving the centrifugal dehydration efficiency of the corrosion-resistant salts.

[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0023] This utility model provides, for example Figure 1-3 The device for dehydrating corrosion-resistant mixed salts shown includes a U-shaped frame 1, a centrifuge cylinder 4 rotatably disposed above the bottom of the U-shaped frame 1 for centrifugal dehydration of corrosion-resistant mixed salts, and a cylinder cover 5 longitudinally slidably disposed below the top of the U-shaped frame 1 and capable of closing or opening the top of the centrifuge cylinder 4. A ring-shaped water receiving seat 7 is detachably installed in the middle of the U-shaped frame 1, with its inner circumferential sidewall slidingly abutting against the outer circumferential sidewall of the centrifuge cylinder 4. A first telescopic member 9 is detachably installed in the middle of the cylinder cover 5, with a pressure plate 13 installed at the bottom end of the first telescopic member 9. Multiple uprights 15 are installed at the bottom inside the cylinder cover 5, with multiple crossbars 17 installed on the circumferential sidewall of each upright 15, and a sloping platform ring plate 16 is installed between the bottom ends of the multiple uprights 15.

[0024] The diameter of the pressure plate 13 is the same as the inner diameter of the centrifuge cylinder 4, and the diameter of the inclined platform ring plate 16 is the same as the inner diameter of the centrifuge cylinder 4. The fact that the diameter of the inclined platform ring plate 16 is the same as the inner diameter of the centrifuge cylinder 4 can prevent crystalline salts or wastewater in the corrosion-resistant mixed salts from entering the lower space of the centrifuge cylinder 4.

[0025] Multiple feed pipes 18 are installed on the top side of the side wall of the centrifuge cylinder 4 to convey the corrosion-resistant salt to be dehydrated into the centrifuge cylinder 4. Multiple water outlet holes 8 are opened on the side wall of the centrifuge cylinder 4, and the contact position between the annular water receiving seat 7 and the centrifuge cylinder 4 is below the water outlet hole 8. When the cylinder cover 5 closes the top of the centrifuge cylinder 4, the contact position between the pressure plate 13 and the centrifuge cylinder 4 is lower than the water outlet hole 8. The wastewater after centrifugation is discharged from the centrifuge cylinder 4 through the water outlet hole 8 and collected by the annular water receiving seat 7.

[0026] A through hole 11 is provided in the middle of the cylinder cover 5. A protective cylinder 12 is detachably installed in the through hole 11. The first telescopic member 9 is detachably installed in the protective cylinder 12. The pressure plate 13 is adapted to each upright 15 and has a through groove 14 for the upright 15 and the crossbar 17 to pass through longitudinally. The first telescopic member 9 extends and retracts longitudinally, thereby driving the pressure plate 13 to move longitudinally in the centrifuge cylinder 4, thereby squeezing the internal corrosion-resistant salt.

[0027] A drive unit 2 is detachably installed on the top of the bottom of the U-shaped frame 1. A bracket 3 is detachably installed on the output end of the drive unit 2. The centrifuge cylinder 4 is detachably clipped into the bracket 3. Second telescopic components 10 are detachably installed at symmetrical positions below the top of the U-shaped frame 1. The bottom ends of multiple second telescopic components 10 are detachably connected to the top of the cylinder cover 5. The second telescopic components 10 can drive the cylinder cover 5 to move down to close the top of the centrifuge cylinder 4, or they can drive the cylinder cover 5 to move up to open the top of the centrifuge cylinder 4, thereby facilitating the removal of the crystalline salt after centrifugation.

[0028] A side support frame 6 is detachably installed in the middle of the U-shaped support frame 1, and an annular water receiving seat 7 is detachably snapped into the side support frame 6. A drain pipe 19 is installed at the bottom of the annular water receiving seat 7.

[0029] In this invention, the centrifuge drum 4 actively rotates to centrifuge and separate the corrosion-resistant salts inside. During the rotation of the centrifuge drum 4, the first telescopic member 9 can drive the pressure plate 13 to move longitudinally inside the centrifuge drum 4, thereby squeezing the corrosion-resistant salts inside and breaking the tight bond between them. During the rotation, the corrosion-resistant salts inside the centrifuge drum 4 are continuously stirred under the action of multiple uprights 15 and multiple crossbars 17. Through the continuous squeezing of the pressure plate 13 and the continuous stirring of the uprights 15 and crossbars 17, the tight bond between the corrosion-resistant salts is quickly and efficiently broken, so that the wastewater inside can break through the restriction of the salts during the centrifugation process and be discharged through the centrifuge drum 4 in a timely manner, thereby improving the centrifugal dehydration efficiency of the corrosion-resistant salts.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
