Description

Technical Field

[0001] The invention relates to the technical field of chemical material processing, in particular to a multi-stage centrifugal processing device for pre-treatment of organic phosphonic acid. Background Art

[0002] In the fields of chemistry, chemical engineering or environmental protection, when it comes to the treatment or separation of organophosphoric acids, we focus on their form and properties in aqueous solutions, waste liquids or mixtures. If organophosphoric acids exist in these media in the form of suspended particles, they can be regarded as solid particles and treated accordingly, such as precipitation, filtration, centrifugation, etc.

[0003] Organic phosphonic acid usually exists in the form of a mixture, so it needs to be centrifuged before use. The common centrifugal treatment method is usually to use a multi-stage centrifuge for treatment. First, the wastewater or mixture containing organic phosphonic acid is sent to the first centrifuge of the device. Under the action of centrifugal force, large suspended particles or components with higher density in the mixture are initially separated. The liquid after preliminary separation enters the subsequent centrifuge unit for multi-stage centrifugal treatment. Each centrifuge adjusts the speed, capacity and processing time according to the different separation targets to achieve a more refined separation effect. During the centrifugation process, organic phosphonic acid may be separated or enriched in a certain phase due to its specific physical properties (such as density, particle size, etc.). Finally, the products after each stage of centrifugation are collected. For the phase containing organic phosphonic acid, further purification treatment can be carried out, such as removing impurities by adsorption, extraction, ion exchange and other methods to improve the purity and quality of organic phosphonic acid.

[0004] However, the melting point of organic phosphoric acid is 42.3 degrees Celsius, which is relatively low. Common centrifugal devices usually send the raw materials directly into the tank body, and then drive the tank body to rotate at high speed through a motor to generate centrifugal force so that large particle suspended matter or high-density components in the mixture are initially separated. During this process, the raw materials inside the tank body will directly rub against the tank body. Long-term friction will cause the inside of the tank body to heat up, and the tank body will continue to heat up when it is driven by the motor to rotate. Therefore, it does not meet the existing needs. In this regard, we have proposed a multi-stage centrifugal treatment device for organic phosphoric acid pretreatment. Summary of the invention

[0019] The present invention has the following beneficial effects: 1. The multi-stage centrifugal treatment device for pretreatment of organic phosphonic acid can effectively convert the pressure energy generated in the centrifuge tank into mechanical energy through the design of the temperature sensing transmission device. When the temperature inside the centrifuge tank rises, the pressure inside it increases. This pressure will squeeze the sliding plate and drive the sliding plate to slide in the rotating cylinder. Since the sliding plate, the connecting folding tube and the upper part of the temperature sensing bin are filled with hydraulic oil, the sliding plate will simultaneously drive the driving slide plate in the temperature sensing bin to slide downward while sliding, thereby driving the buffer device to move. Through this design, it is effectively ensured that when the temperature inside the centrifuge tank changes, the temperature sensing transmission device can be used to transmit this change to the buffer device and the spray device, thereby driving the nozzle to cool the centrifuge tank and spray it, effectively controlling the temperature of the centrifuge tank in real time, thereby preventing the raw materials in the centrifuge tank from changing their physical properties due to high temperature, resulting in the inability to separate the organic phosphoric acid.

[0020] 2. The multi-stage centrifugal treatment device for pretreatment of organic phosphonic acid effectively utilizes the mechanical force transmitted by the temperature sensing transmission device through the design of the cooling device, and transmits this mechanical force to the spraying device, driving the spraying device to perform the spraying process. However, the mechanical energy transmission of the temperature sensing transmission device is real-time, but the heat generated by the friction between the materials and the rotation of the tank body in the centrifuge is not always higher than the established threshold. Therefore, the design of the cooling device can slow down the transmission of mechanical energy until the internal temperature reaches the established threshold. The cooling device transmits the mechanical energy to the spraying device and drives the spraying device to cool the centrifuge tank and spray it.

[0021] 3. The multi-stage centrifugal treatment device for pretreatment of organic phosphonic acid, through the design of the rotating device and the swinging device, enables the spray sleeve to drive the rotating block to rotate a certain angle during the descent process. This design allows the inclined nozzle to further increase the inclination angle. At the same time, under the driving rotation of the rotating device, the nozzle can be driven to rotate with a larger rotation radius, further increasing the spraying range of the nozzle.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: This example is intended to help solve the problem that the temperature inside the tank increases due to friction between the raw materials inside the tank and the rotation of the tank itself. Please refer to Figures 1 to 11 , A multi-stage centrifugal treatment device for pretreatment of organic phosphonic acid includes a supporting device 1, the supporting device 1 includes an outer shell 101, a centrifuge tank 103 is installed in the outer shell 101, a temperature sensing transmission device 2 is installed at one end of the centrifuge tank 103, a buffer device 3 is installed at the upper end of the outer shell 101, and the buffer device 3 is connected to a spray device 4 for cooling the centrifuge tank 103.

[0036] The buffer device 3 comprises a partition plate 301 fixedly connected in the housing 101 , a pressing plate 303 is slidably connected in the housing 101 , and a spray device 4 is mounted on the pressing plate 303 .

[0037] The spray device 4 includes an I-shaped drive rod 403 rotatably connected to the extrusion plate 303, the other end of the I-shaped drive rod 403 is arranged in the spray sleeve 401, the spray sleeve 401 is installed in the sliding hole 408, the sliding hole 408 is opened in the partition 301, and a rotating block 409 is installed at the bottom of the spray sleeve 401, and a spray head 412 is installed on the rotating block 409.

[0038] When the temperature inside the centrifuge tank 103 rises, since the volume of the centrifuge tank 103 is fixed, the temperature rises and the pressure inside it increases. Through this change and the temperature sensing transmission device 2, the nozzle 412 is driven to spray cooling water on the outer surface of the centrifuge tank 103. In this way, the temperature inside the centrifuge tank 103 can be effectively reduced, which plays a cooling role and effectively prevents the physical properties of organic phosphoric acid from changing due to excessive temperature, resulting in the inability to carry out the pretreatment process of centrifugal separation.

[0039] A support base 102 is fixedly connected to the bottom of the shell 101, and a rotating shaft No. 104 is fixedly connected to one end of the centrifuge tank 103 away from the temperature sensing transmission device 2. A feed port 105 is opened in the rotating shaft No. 104. The rotation of the rotating shaft No. 104 is driven by a driving motor 107, and the driving motor 107 is connected to the rotating shaft No. 104 through a transmission belt 106. (The above structure and its working principle are the existing technology for the operation of the centrifuge, and this scheme does not describe its working principle and beneficial effects).

[0040] A discharge assembly 7 is provided at the bottom of the shell 101, and the discharge assembly 7 includes a No. 1 discharge port 702 and a No. 2 discharge port 704 opened at both ends of the centrifuge tank 103. A No. 1 discharge port 703 and a No. 2 discharge port 705 are respectively opened at both ends of the shell 101. A water drain port 701 is opened on the side wall of the shell 101. A partition plate 706 is fixedly connected inside the shell 101, and the centrifuge tank 103 is rotatably connected inside the partition plate 706.

[0041] When the centrifuge rotates, large suspended particles or components with higher density in the mixture will be separated. The separated materials will move to both sides under the action of centrifugal force and will be discharged from the centrifuge tank 103 into the housing 101 through the No. 1 discharge port 702 and the No. 2 discharge port 704 designed on both sides of the centrifuge tank 103. The opening of the drain port 701 is convenient for discharging the water sprayed by the nozzle 412. The No. 1 discharge port 703, the drain port 701 and the No. 2 discharge port 705 are separated by the partition plate 706 to prevent water mist from affecting the separated raw materials. In order to ensure the sealing of the internal air pressure when the centrifuge is working, the No. 1 discharge port 703, the No. 2 discharge port 705 and the feed port 105 will be blocked when the centrifuge rotates to ensure the sealed environment in the centrifuge tank 103.

[0042] The temperature sensing transmission device 2 includes a rotating cylinder 201 fixedly connected to the centrifuge tank body 103, a sliding plate 202 is slidably connected inside the rotating cylinder 201, one end of the sliding plate 202 is fixedly connected to a temperature sensing spring 203, the other end of the temperature sensing spring 203 is fixedly connected inside the rotating cylinder 201, the rotating cylinder 201 is located on a side of the centrifuge tank body 103 and is fixedly connected to an anti-slip plate 204, one end of the rotating cylinder 201 away from the anti-slip plate 204 is fixedly connected to a connecting folded tube 205, the connecting folded tube 205 is connected to the rotating cylinder 201, the other end of the connecting folded tube 205 is connected to a temperature sensing bin 206, the temperature sensing bin 206 is fixedly connected to the top of the outer shell 101, and a driving slide plate 207 is slidably connected inside the temperature sensing bin 206.

[0043] The design of the temperature sensing transmission device 2 can effectively convert the pressure energy generated in the centrifuge tank 103 into mechanical energy. When the temperature inside the centrifuge tank 103 rises, since the volume of the centrifuge tank 103 remains fixed, the temperature rises and the pressure inside it increases. At this time, this pressure will be transmitted to the sliding plate 202 in the rotating cylinder 201. This pressure will squeeze the sliding plate 202 and drive the sliding plate 202 to slide in the rotating cylinder 201. Since the sliding plate 202, the connecting folding tube 205 and the upper half of the temperature sensing chamber 206 are filled with hydraulic oil, the sliding plate 202 will simultaneously drive the driving slide plate 207 in the temperature sensing chamber 206 to slide downward while sliding, thereby driving the buffer device 3 to move. This design effectively ensures that when the temperature inside the centrifuge tank 103 changes, the change can be transmitted to the buffer device 3 and the spray device 4 through the temperature sensing transmission device 2, thereby driving the nozzle 412 to perform cooling spray treatment on the centrifuge tank 103, thereby effectively controlling the temperature of the centrifuge tank 103 in real time, thereby preventing the raw materials in the centrifuge tank 103 from changing their physical properties due to high temperature, resulting in the inability to separate the organic phosphoric acid.

[0044] A buffer device 3 is installed below the driving slide 207, and the buffer device 3 includes a pressing sleeve 306 fixedly connected to the driving slide 207, and an inner rod 307 is slidably connected in the pressing sleeve 306, and the inner rod 307 is inserted in the connecting groove 305. The connecting groove 305 is provided in the temperature sensing chamber 206 and the outer shell 101, and a return spring 308 is fixedly connected to the bottom of the pressing sleeve 306, and the other end of the return spring 308 is fixedly connected to the temperature sensing chamber 206, and the other end of the inner rod 307 is fixedly connected to the extrusion plate 303, and a spray device 4 is installed on the extrusion plate 303. A water hole 302 is provided on the side wall of the outer shell 101, and a lifting spring 304 is fixedly connected to the bottom of the extrusion plate 303, and the other end of the lifting spring 304 is fixedly connected to the partition 301.

[0045] The design of the buffer device 3 effectively utilizes the mechanical force transmitted by the temperature sensing transfer device 2, and transmits this mechanical force to the spray device 4, driving the spray device 4 to perform the spraying process. However, the mechanical energy transmission of the temperature sensing transfer device 2 is real-time, but the heat generated by the friction between the materials and the rotation of the tank body in the centrifuge is not always higher than the established threshold. Therefore, the design of the buffer device 3 can slow down the transmission of mechanical energy until the internal temperature reaches the established threshold. The buffer device 3 will then transfer the mechanical energy to the spray device 4 and drive the nozzle 412 to perform cooling spray on the centrifuge tank body 103.

[0046] When the driving slide 207 descends, the pressing sleeve 306 fixedly connected to the driving slide 207 descends synchronously. At this time, the extrusion plate 303 does not move because it is supported by the lifting spring 304. At this time, the No. 1 inner rod 307 fixedly connected to the extrusion plate 303 does not descend either. When the pressing sleeve 306 descends to abut against one end of the No. 1 inner rod 307, the driving slide 207 continues to descend, which will drive the pressing sleeve 306 to drive the No. 1 inner rod 307 and the extrusion plate 303 to descend synchronously. The descent of the extrusion plate 303 will drive the spray device 4 to operate and then drive the spray head 412 to spray. Through this design, the descent of the extrusion plate 303 requires a downward pressure This can only be achieved when the sleeve 306 descends to a certain height. The displacement of this descent can be regarded as a change in temperature from an initial temperature to a predetermined threshold value. The setting of the predetermined threshold value can be determined by changing the height of the No. 1 inner rod 307 to the top of the pressing sleeve 306. This design effectively prevents the nozzle 412 from starting to spray water to cool the centrifuge tank 103 at the moment when the temperature of the centrifuge tank 103 changes. The design of the temperature-sensing spring 203 ensures that when the temperature in the centrifuge tank 103 decreases, the sliding plate 202 can be quickly driven to reset. The water hole 302 can be connected to the water supply equipment through a pipeline to continuously inject cooling water into the space between the extrusion plate 303 and the partition 301.

[0047] A water inlet hole 402 is provided at the upper end of the spray sleeve 401, and a base 404 is fixedly connected inside the spray sleeve 401. A blocking spring 406 is fixedly connected to the base 404, and the other end of the blocking spring 406 is fixedly connected to a blocking plate 405. A transmission rod 407 is fixedly connected to one side of the blocking plate 405, and the other end of the transmission rod 407 is fixedly connected to the bottom of the I-shaped driving rod 403.

[0048] When the extrusion plate 303 descends, the I-shaped driving rod 403 descends synchronously, and the transmission rod 407 located at the bottom of the I-shaped driving rod 403 will drive the blocking plate 405 to move downward. At this time, the spray sleeve 401 divided by the blocking plate 405 is reconnected. At this time, the cooling water located in the outer shell 101 will enter the spray sleeve 401 through the water inlet hole 402, and enter the bottom of the spray sleeve 401 through the opened base 404. Through this design, the timing of water flow of the nozzle 412 can be effectively controlled.

[0049] When the sealing plate 405 moves downward, one end of the I-shaped driving rod 403 abuts against one side of the abutment base 404. At this time, the I-shaped driving rod 403 continues to move downward to drive the spray sleeve 401 to move downward as a whole. This design facilitates the spray sleeve 401 to rotate through the design of the rotating device 5.

[0050] The lower end of the spray sleeve 401 is rotatably connected to a rotating block 409 , one end of the rotating block 409 is connected to a hose 411 , and the other end of the hose 411 is connected to a channel 410 . The channel 410 is opened in the spray sleeve 401 , and a side wall of the rotating block 409 is provided with an inclined surface 607 .

[0051] The spray sleeve 401 is connected to the rotating block 409 by using a hose 411 and a channel 410, wherein the design of the hose 411 can ensure the connection of the water path when the rotating block 409 rotates, thereby ensuring that the flow of water will not be blocked.

[0052] Embodiment 2: This embodiment is intended to help solve the problem of limited spraying range of the nozzle 412 when spraying. This embodiment is an explanation based on Embodiment 1. For details, please refer to Figures 1 to 11 , A rotating device 5 is disposed in the sliding hole 408 . The rotating device 5 includes a spiral groove 501 opened in the partition plate 301 . A rotating block 502 is slidably connected in the spiral groove 501 . The rotating block 502 is fixedly connected to the outer wall of the spray sleeve 401 .

[0053] The design of the rotating device 5 allows the spray sleeve 401 to rotate during the descent process. Through this rotation, the inclined nozzle 412 can be rotated and sprayed. This design allows the inclined nozzle 412 to further increase the spraying range of the nozzle 412. At the same time, the rotating block 502 arranged in the spiral groove 501 can support the spray sleeve 401, effectively ensuring the stability of the spray sleeve 401.

[0054] Example 3: This example is intended to promote the solution of the problem of further improving the spraying range when the nozzle is spraying. This example is an explanation based on Example 2. For details, please refer to Figures 1 to 11 , A swing device 6 is installed at the bottom of the spray sleeve 401, and the swing device 6 includes a telescopic sleeve 601 fixedly connected to the bottom of the spray sleeve 401, a telescopic inner rod 602 is slidably connected inside the telescopic sleeve 601, one end of the telescopic inner rod 602 is fixedly connected to a telescopic spring 603, and the other end of the telescopic spring 603 is fixedly connected inside the telescopic sleeve 601.

[0055] The other end of the telescopic inner rod 602 is fixedly connected to a resisting plate 604 , one end of the resisting plate 604 resists an inclined surface 607 , and the partition plate 301 is fixedly connected to a limiting ring 605 at the bottom of the sliding hole 408 .

[0056] The design of the swing device 6 enables the spray sleeve 401 to drive the rotating block 409 to rotate a certain angle during the descent process. Through this design, the inclined nozzle 412 can further increase the inclination angle. At the same time, under the drive rotation of the rotating device 5, the nozzle 412 can be driven to rotate with a larger rotation radius, further increasing the spraying range of the nozzle 412.

[0057] Before the spray sleeve 401 rotates and descends, the abutment plate 604 and the inclined surface 607 are in contact with each other, and no interaction force (such as Fig.11 As shown in the figure, when the spray sleeve 401 drops to a certain height, the contact plate 604 at the bottom of the spray sleeve 401 is locked by the limit ring 605. At this time, the telescopic inner rod 602 will slide in the telescopic sleeve 601. At this time, the contact plate 604 will apply pressure to the inclined surface 607. At this time, the rotating block 409 will rotate to a certain angle. At the same time, the rotating block 409 continues to rotate under the drive of the rotating device 5. Through this design, the rotation of the spray head 412 is turbine-shaped, and its rotation angle is continuously increased. This design further improves the spraying range of the spray head 412, and further ensures the cooling effect on the centrifuge tank 103.

[0058] The bottom surface of the abutment plate 604 is provided with a ball bearing 606.
