Description

Technical Field

[0001] The utility model relates to the field of chemical production, in particular to a centrifugal protection device for preventing free water from escaping in the chemical industry. Background Art

[0002] In chemical production, centrifugal crystallization technology is used to purify and separate various chemicals, such as ammonium sulfate, sodium sulfate, and other inorganic salt products. Through centrifugal crystallization, high-purity crystalline products can be obtained, meeting the stringent requirements of chemical production for raw material and product quality.

[0003] However, some chemical products with cumulative effects can lose free water molecules during crystallization and cause explosions. During centrifugation, residual chemical products accumulate in the upper and lower gaps within the centrifuge chamber. These chemicals lose free water molecules during repeated centrifugation and can explode. Therefore, a centrifugal protection device is required to prevent the free water from escaping.

[0004] Currently, to effectively prevent the loss of free water, low-pressure steam is typically injected into the centrifuge chamber to increase the humidity of the internal environment, ensuring that the free water molecules in the chemical product are properly protected without affecting the normal operation of the centrifuge. However, steam is directly input into the centrifuge through a pipe. When the centrifuge is started, it will cause the internal centrifugal bucket to rotate rapidly. This causes the centrifuge to vibrate rapidly and intensively, causing the steam pipeline that inputs steam to vibrate, generating shear forces on the pipeline. Long-term operation may cause damage to the steam pipeline and steam leakage. On the other hand, if the steam pressure in the centrifuge chamber exceeds the reasonable range, it will not only waste steam resources but also cause the water content of the chemical product after centrifugation to exceed the standard. More seriously, the continued increase in steam pressure may cause a sharp increase in steam temperature, which in turn causes the free water molecules in the chemical product to detach, increasing the potential risk of product combustion or explosion. Therefore, a centrifugal protection device for preventing free water detachment in the chemical industry is proposed to address this problem. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a centrifugal protection device for preventing the separation of free water in the chemical industry, which aims to improve the problems in the prior art where the centrifuge is turned on, causing the steam pipeline for inputting steam to vibrate, causing damage to the steam pipeline, and the increase in steam pressure may cause the steam temperature to rise, resulting in the separation of free water molecules in the chemical product.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a centrifugal protection device for preventing free water from escaping in a chemical industry, comprising a fixed base, a centrifuge is provided on the top of the fixed base, an air intake pipe is provided on the right side of the centrifuge, a steam valve is provided on the outer periphery of the air intake pipe, a connecting hose is sleeved on the right end of the air intake pipe, an air intake assembly for inputting low-pressure steam is sleeved on the right side of the connecting hose, an extrusion ring is contacted on the outer periphery of the connecting hose, a deformation notch is provided on the inner side of the extrusion ring, an extrusion inclined surface is provided on the outer side of the extrusion ring, the extrusion inclined surface on the right side of the extrusion ring contacts a fixed extrusion block, a fixed sleeve is fixedly connected to the right side of the fixed extrusion block, a rotating seat is fixedly connected to the outer side of the fixed sleeve, a fixing bolt is provided on the rotating thread inside the rotating seat, the inner side of the fixing bolt contacts a movable extrusion block, and an exhaust valve is provided on the left side of the centrifuge.

[0009] As a further description of the above technical solution:

[0010] The air intake assembly includes a steam pipeline, the left end of the steam pipeline is sleeved inside the connecting hose, and a pressure reducing valve is arranged on the periphery of the steam pipeline.

[0011] As a further description of the above technical solution:

[0012] The outer periphery of the movable extrusion block is slidably connected to the interior of the fixed circular sleeve.

[0013] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:

[0016] The bottom end of the sealing sleeve is fixedly connected to the top surface of the centrifuge.

[0017] As a further description of the above technical solution:

[0021] The utility model has the following beneficial effects:

[0022] 1. In the utility model, by setting a fixed extrusion block, an extrusion ring, and a movable extrusion block, the fixing bolt is rotated so that the extrusion ring can tightly fix the connecting hose to the air inlet pipe and the steam pipeline, thereby achieving good air tightness, thereby reducing the impact of centrifuge vibration on the steam pipeline, preventing damage to the steam pipeline, reducing the possibility of steam leakage, and ensuring safe production.

[0023] 2. In the present invention, an adjusting block and an air pressure sensor are provided, and the air pressure inside the sealing sleeve is adjusted by rotating the adjusting bolt. When the air pressure inside the centrifuge is too high, the gas will lift up the sealing piston ring, exposing the pressure relief hole, and the gas inside the centrifuge will be discharged to the outside, ensuring that the internal air pressure will not be too high, causing the crystals to separate from the free water, thereby ensuring safe production.
