Description

Technical Field

[0001] This utility model relates to the technical field of crystallization separation devices, and in particular to a centrifugal separation device for crystallizing phosphorus-containing compounds. Background Technology

[0002] Phosphorus-containing compounds refer to chemical substances containing phosphorus (P). They are widely found in nature and in artificially synthesized materials and have important chemical, biological, and industrial applications. For example, potassium dihydrogen phosphate has a wide range of applications in agriculture, medicine, and food. Its processing requires the use of crystallization centrifugal separation devices. Centrifugation is a commonly used solid-liquid separation method. It uses centrifugal force to quickly separate crystals and mother liquor, and has the advantages of high separation efficiency and good effect. With the continuous development of chemical production technology, higher requirements have been placed on potassium dihydrogen phosphate crystallization centrifugal separation devices.

[0003] Place the potassium dihydrogen phosphate crystals to be separated in a centrifuge. The centrifuge will precipitate the potassium dihydrogen phosphate from the solution as crystals, which can then be collected.

[0004] Existing centrifugal separation devices for potassium dihydrogen phosphate crystallization lack the function of uniformly discharging raw materials during the feeding process. Discharging too quickly will cause the centrifugation speed to be slow. At the same time, it is not easy to counteract the shock generated by the centrifuge. Therefore, a centrifugal separation device for phosphorus-containing compound crystallization is proposed. Utility Model Content

[0016] Beneficial effects

[0017] This invention provides a centrifugal separation device for crystallizing phosphorus-containing compounds. It has the following beneficial effects:

[0018] 1. Through the action of the uniform feeding mechanism, the potassium dihydrogen phosphate raw material to be separated can be evenly dropped into the centrifuge.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a centrifugal separation device for crystallizing phosphorus-containing compounds, including a centrifuge 1, a uniform feeding mechanism 2 provided at the top of the centrifuge 1, and a shock-absorbing mechanism 3 provided at the bottom of the centrifuge 1.

[0030] The uniform feeding mechanism 2 includes a feed hopper 201 fixedly installed on the top of the centrifuge 1, and a feeder 202 is provided on the top of the inner cavity of the centrifuge 1.

[0031] Specifically, the feeder 202 is equipped with a pressure pump. Potassium dihydrogen phosphate raw material is placed in the feed hopper 201, and the pressure pump pressurizes the raw material to a certain pressure and sprays it out.

[0032] The bottom of the feeder 202 is fixedly connected to a bent pipe 203, and a spray head 204 is provided at one end of the bent pipe 203. Arc-shaped groove blocks 205 are symmetrically arranged in the inner cavity of the feed hopper 201.

[0033] Specifically, the spray head 204 is located on one side of the inner surface of the centrifugal rotating component in the inner cavity of the centrifuge 1. The feeder 202 pressurizes and sprays the raw material onto one side of the inner surface of the centrifugal component through the bent pipe 203, and the potassium dihydrogen phosphate raw material is separated under the action of centrifugation.

[0034] The feed hopper 201 has a rotating shaft 206 inside. Multiple liquid separating plates 207 are circumferentially distributed on the outer surface of the rotating shaft 206. A motor 208 is fixedly connected to one end of the rotating shaft 206 that extends to the outside of the feed hopper 201.

[0035] Specifically, when multiple dispensing discs 207 are rotated by the rotating shaft 206, the raw material can be evenly distributed into several portions, the raw material can be rotated from top to bottom, and the raw material can flow downwards evenly, maintaining the normal flow distribution of the centrifuge 1.

[0036] The centrifuge 1 has a hole at the top that is compatible with the feed hopper 201, and the feeder 202 is installed directly below the hole. The rotating shaft 206 is rotatably connected to the inside of the feed hopper 201.

[0037] Specifically, when the several liquid distribution plates 207 rotate, the end that is not connected to the rotating shaft 206 contacts the arc-shaped groove block 205, thereby improving the sealing degree of the two arc-shaped groove blocks 205 and the liquid distribution plates 207.

[0038] Furthermore, the potassium dihydrogen phosphate raw material is poured into the cavity from the top of the feed hopper 201. The operation of the motor 208 is controlled, and the motor 208 drives the rotating shaft 206 to rotate, thereby driving the liquid separator 207 to rotate, dividing the raw material in the cavity of the feed hopper 201 into several equal portions and diverting them downwards. Under the action of the feeder 202, the equally divided raw material is sprayed into the inner cavity of the centrifuge 1, so that the potassium dihydrogen phosphate raw material is fully separated.

[0039] Example 2

[0040] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a shock-absorbing mechanism 3 to counteract the vibrations generated during the operation of the centrifuge 1.

[0041] The shock absorption mechanism 3 includes a housing 301 movably mounted on the outside of the centrifuge 1. An annular plate 302 is mounted on the inner surface of the housing 301, and several damping rods 303 are distributed around the top circumference of the annular plate 302.

[0042] Specifically, the housing 301 is fitted onto the outside of the centrifuge 1, and the centrifuge 1 is stabilized in the housing 301 under the action of several damping rods 303.

[0043] A limiting rod 304 is movably installed on the inner circumference of the annular plate 302. A limiting ring 305 is fixedly installed on the outer surface of the limiting rod 304. A spring 306 is provided at the bottom of the limiting ring 305.

[0044] Specifically, when the top centrifuge 1 is in operation, the spring 306 counteracts the bumps generated by the centrifuge 1 during operation, ensuring the stable operation of the centrifuge 1.

[0045] The other ends of the damping rod 303 and the limiting rod 304 are fixedly installed at the bottom of the centrifuge 1. Several limiting rods 304 are slidably connected inside the annular plate 302, and the spring 306 is located outside the limiting rod 304.

[0046] Furthermore, when the centrifuge 1 is working, it can counteract the resonance generated by the centrifuge 1. Under the action of the spring 306, when the centrifuge 1 is pressed down by the force during operation, the spring 306 absorbs the energy of the bump. At this time, under the action of the damping rod 303, the centrifuge 1 is only allowed to move downward in the vertical direction.

[0047] Working Principle: The centrifuge 1 has a centrifugal separation structure inside, and its working principle is the same as that of existing disclosed ones. Potassium dihydrogen phosphate raw material is poured into the cavity from the top of the feed hopper 201. The motor 208 is controlled to run, and the motor 208 drives the rotating shaft 206 to rotate inside the feed hopper 201. The rotating shaft 206 drives several distributing plates 207 on its outer side to rotate, dividing the raw material at the top of the feed hopper 201 into several equal portions that flow downwards. These portions flow downwards through the holes that match the centrifuge 1 and the feed hopper 201, and enter the feeder 202. Under the action of the feeder 202, the material flows through the bent pipe 203 and the spray head 204. With the assistance of the centrifuge, the equally distributed raw materials are sprayed into the inner cavity of the centrifuge 1 for potassium dihydrogen phosphate separation. When the centrifuge 1 is working, it is necessary to counteract certain bumps. At this time, under the action of the spring 306, when the centrifuge 1 is pressed down by the force during operation, the spring 306 absorbs the energy of the bumps. At this time, under the action of the damping rod 303, the centrifuge 1 is only allowed to move downward in the vertical direction. When the spring 306 is pushed downward through the limiting ring 305 and deforms, the limiting rod 304 moves downward inside the annular plate 302 to counteract the bumps generated by the centrifuge 1 and ensure that the centrifuge 1 can operate normally.
