Description

Technical Field

[0001] This utility model relates to the field of piperazine polyoxyethylene ether technology, specifically to a static layering device for preparing piperazine polyoxyethylene ether. Background Technology

[0002] Polyoxyethylene ether, also known as polyethylene oxide or polyepoxyethylene, is a crystalline, thermoplastic, water-soluble polymer. Piperazine polyoxyethylene ether is a type of polyoxyethylene ether made from piperazine as an initiator. In the production process, the crude material needs to be mixed with the solvent and then allowed to stand for stratification.

[0003] Currently, when using static stratification devices, there is a lack of auxiliary slow-flow feeding mechanisms. Typically, the liquid used for preparing polyoxyethylene ether is directly injected into the device for static stratification. However, due to the violent shaking of the liquid during injection, the static stratification time is relatively long, thus increasing the preparation efficiency. Therefore, a static stratification device for preparing piperazine polyoxyethylene ether is proposed to facilitate the addition of an auxiliary slow-flow feeding mechanism. By utilizing diversion conveying and a spiral structure, the stability of the liquid entering the device is improved, the static stratification time is shortened, and the preparation efficiency is increased, thereby improving the overall performance.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] To facilitate the addition of an auxiliary slow-flow feeding mechanism, shorten the settling and stratification time, and improve preparation efficiency, thereby enhancing the overall performance, such as... Figure 1-3 As shown, the present invention discloses a static stratification device for preparing piperazine polyoxyethylene ether, comprising a cylindrical body 1, a flow-dividing component 5, and a driving component 6. The top of the cylindrical body 1 is bolted to a fixed seat 2. A sliding frame 4 is slidably connected inside the cylindrical body 1. A flow-dividing groove 3 is provided on the top of the sliding frame 4. A flow-dividing component 5 is provided between the flow-dividing groove 3 and the sliding frame 4. The driving component 6 is provided at the bottom of the fixed seat 2 inside the cylindrical body 1.

[0028] The diversion assembly 5 includes a flow guide tube 501, a column 502 is bolted inside the flow guide tube 501, and a spiral blade 503 is welded to the periphery of the column 502.

[0029] In use, the diversion channel 3, sliding frame 4, guide tube 501, column 502 and spiral blade 503 can increase the slow-flow feeding mechanism. By using the diversion and slow flow method, the stability of the preparation liquid during the filling process is improved, and it is less likely to shake. This shortens the settling and stratification time and also helps to improve the preparation efficiency.

[0030] To improve, for example, such as Figure 1 , Figure 2As shown, the present invention also includes the following: the drive assembly 6 includes a lead screw 601, and the cylinder 1 and the fixed seat 2 are both mounted on the lead screw 601 through bearings, and the lead screw 601 passes through the diversion groove 3 through a reserved hole. A corresponding ball slider 602 is provided around the lead screw 601, and the ball slider 602 is connected to the sliding frame 4 by bolts.

[0031] In use, the ball screw 601 and ball slider 602 can be used to drive the sliding frame 4 to move vertically back and forth, thereby adjusting its height position.

[0032] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a water outlet 401 at the bottom of the sliding frame 4, and the water outlet 401 is connected to the guide tube 501. A water pump 9 is connected to one side of the tube 1 by bolts, and the water inlet end of the water pump 9 is connected to the top of the diversion channel 3 by a hose.

[0033] During use, the water outlet 401 facilitates the entry and exit of the preparation liquid and the layered liquid, and the water pump 9 facilitates the extraction of the layered liquid.

[0034] For example, such as Figure 1 As shown, the present invention also includes a servo motor 7 connected to the top of the fixed base 2 by bolts, and the servo motor 7 is connected to the lead screw 601 via a drive shaft.

[0035] In use, the servo motor 7 facilitates the rotation of the lead screw 601.

[0036] For example, such as Figure 2 As shown, the present invention also includes a drain outlet 101 on the other side of the cylinder 1, and a support base 102 is bolted to the bottom of the cylinder 1.

[0037] During use, the drain outlet 101 facilitates the discharge of residual waste liquid at the bottom, and the support base 102 facilitates the improvement of the stability of the device. The bottom of the support base 102 is connected with an anti-slip pad by adhesive bonding.

[0038] For example, such as Figure 2 As shown, the present invention also includes a feeding hopper 8 connected to one side of the fixed base 2 by bolts, a guide pipe 801 provided at the bottom of the feeding hopper 8, and the guide pipe 801 connected to the diversion channel 3, and a control valve 802 provided at the discharge end of the guide pipe 801.

[0039] During use, the preparation liquid is easily injected into the cylinder 1 for static stratification via the feeding hopper 8, the guide pipe 801, and the control valve 802.

[0040] In use, the mixed piperazine polyoxyethylene ether preparation liquid is first poured into the feeding hopper 8. It is then diverted into the guide cylinder 501 through the guide pipe 801 and the diversion groove 3 of the feeding hopper 8. After passing through the spiral structure of the column 502 and the spiral blade 503, it slowly flows into the bottom of the cylinder 1. At the same time, the servo motor 7 is manually turned on to drive the lead screw 601 to rotate. The ball slider 602 drives the sliding frame 4 to move vertically upward, thus slowly completing the feeding action. The diversion and spiral structure are used to inject the preparation liquid into the device for static stratification. The slow flow method can improve the stability of the liquid and make it less prone to shaking, thereby shortening the static stratification time and improving production efficiency.

[0041] After the sedimentation and stratification are completed, the servo motor 7 is manually turned on to drive the lead screw 601 to rotate according to the height of the impurity water or the stratified liquid. The position of the sliding frame 4 and the outlet 401 is slowly adjusted by the ball slider 602. After the control valve 802 is closed, the water pump 9 is manually turned on to extract the stratified liquid or impurity water through the diversion component 5 to complete the auxiliary discharge. The overall structure is simple and easy to operate, making it more convenient and flexible to use. It is also beneficial to improve the preparation efficiency of piperazine polyoxyethylene ether.
