Description

[0001] The invention relates to a polystyrene blending system, in particular to a high-efficiency blending system applied in the polystyrene blending field and used for polystyrene production. Background Art

[0002] Polystyrene is a colorless and transparent thermoplastic plastic made from the polymerization of styrene. During processing, it usually involves the mixing of multiple materials to ensure the uniformity of the quality of the processed polystyrene products. However, in addition to the mixing operation of multiple raw materials, proportional blending operations are also required to ensure the quality of polystyrene products. In order to control the accuracy of the proportional blending, certain quantitative operations need to be taken during mixing.

[0004] When existing proportional blending systems are blending multiple raw materials, they usually control the discharge volume by controlling the cross-sectional area and discharge time during discharge, thereby achieving quantitative discharge. However, in actual operation, when polystyrene materials are blended, they are usually blended according to a blending ratio in one blending device. When the single blending amount is not large and there are multiple blending ratio requirements, multiple blending devices are required to perform blending operations of different ratios at the same time, resulting in a large space occupied by the blending operation site and the equipment cost of the blending operation is forced to increase. Summary of the Invention

[0034] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figure 1 The system is shown as an efficient blending system for polystyrene production, comprising a blending cylinder 1 and auxiliary material cylinders 2 arranged on both sides of the blending cylinder 1. The tops of the blending cylinder 1 and the two auxiliary material cylinders 2 are both provided with feed ports. A driving motor 3 is installed on the top of the blending cylinder 1. Figure 6 As shown, the output end of the driving motor 3 is connected to a rotating rod 8 located inside the mixing cylinder 1, and a deformed stirring rod 7 is fixed around the surface of the rotating rod 8. Figure 11 As shown, a plurality of partition plates 6 are slidably sleeved on the surface of the rotating rod 8, and a plurality of deformed stirring rods 7 are provided inside the partition plates 6 with corresponding through grooves 61. Figure 10 As shown, multiple electromagnetic rings 81 are arranged equidistantly inside the rotating rod 8, and a circular groove matching the rotating rod 8 is provided at the center of the dividing plate 6, and the inner wall of the circular groove is coated with a magnetic coating that attracts the electromagnetic ring 81;

[0037] Figure 7 As shown, the deformable stirring rod 7 includes a rigid round rod 71 fixedly mounted on the surface of the rotating round rod 8. A variable electro-hydraulic layer 72 is arranged on the outer side of the rigid round rod 71. An insulating rubber sleeve 74 is connected to the outer side of the variable electro-hydraulic layer 72. Two symmetrically arranged electromagnetic blocks 73 are arranged along the axis on the surfaces of the insulating rubber sleeve 74 and the rigid round rod 71 close to each other. The two electromagnetic blocks 73 repel each other when energized. The surfaces of the two electromagnetic blocks 73 are coated with insulating material.

[0038] The interior of the transformer fluid layer 72 is connected with a conductive wire, and the interior of each partition plate 6 is equipped with an air pressure sensor.

[0039] Specifically, when a blending operation is required, the auxiliary materials in the auxiliary material cylinder 2 are mixed into the blending cylinder 1 according to a certain proportion, and then the driving motor 3 is started to drive the rotating rod 8 and the deformed stirring rod 7 on the surface to perform a mixing operation, thereby achieving a blending process;

[0040] When a multi-proportion blending operation is required, the adsorption position of the partition plate 6 on the surface of the rotating rod 8 is adjusted according to the ratio of the volume of the blended amount to be occupied by the blending cylinder 1 after calculation by the analysis module. In the initial state, the electromagnetic ring 81 corresponding to the lowest partition plate 6 and the electromagnetic rings 81 below it are all in the power-off state, and the lowest partition plate 6 slides down to the corresponding position by gravity (because the air pressure sensor can be used to monitor the height of the partition plate 6, which can then indirectly reflect the height position of the partition plate 6 on the surface of the rotating rod 8 in the blending cylinder 1). After the lowest partition plate 6 moves to the calculated position, the electromagnetic ring 81 at the corresponding position is started to limit the partition plate 6, thereby forming an isolated cavity.

[0041] During the descent of the partition plate 6, the difference between the cross-section of the through groove 61 and the cross-section of the deformed stirring rod 7 prevents the partition plate 6 from being intercepted by the deformed stirring rod 7, thereby ensuring its smooth descent.

[0042] Figure 9 As shown, in addition, after the partition plate 6 is displaced to the calculated position and the electromagnetic ring 81 at the corresponding position is synchronously started for constraint, in order to ensure that the partition plate 6 will not continue to slide down when it encounters material load in the future (because the material is too heavy, the gravity is greater than the magnetic attraction force between the partition plate 6 and the electromagnetic ring 81, causing the partition plate 6 to slide down), it is necessary to start the electromagnetic block 73 in the deformable stirring rod 7 closest to the bottom of the partition plate 6 after the electromagnetic ring 81 is started, so that the two electromagnetic blocks 73 generate a mutually repulsive force after being energized, thereby driving the insulating rubber sleeve 74 to produce a lateral tensile deformation (such as Figure 8 As shown), until the cross-sectional width of the insulating rubber sleeve 74 after transverse stretching is larger than the through groove 61, the conductive wire in the transformer liquid layer 72 is energized, and then the electromagnetic block 73 is de-energized. After the conductive wire is energized, the transformer liquid layer 72 solidifies, which can play a supporting and lifting role, thereby making the dividing plate 6 more stable in the corresponding position.

[0043] In this way, by flexibly adjusting the positions of multiple dividing plates 6 on the surface of the rotating rod 8, the mixing space in the mixing cylinder 1 can be divided. Compared with the adjustment of a single fixed space, the present application can adjust the volume of the divided space according to different mixing ratios and quantities. While performing mixing of multiple ratios, it can also adapt to simultaneous mixing of different ratios and quantities.

[0044] The attraction force between the electromagnetic ring 81 and the magnetic coating is greater than the gravity of the dividing plate 6 , and the cross-sectional width of the through slot 61 is greater than the cross-sectional width of the conductive wire in the deformed stirring rod 7 when not energized.

[0045] Specifically, since the magnetic attraction force between the electromagnetic ring 81 and the magnetic coating is greater than the gravity of the dividing plate 6, in the initial state (that is, when the dividing plate 6 is at the top), the dividing plate 6 can be stably adsorbed on the surface of the rotating round rod 8. In addition, the cross-sectional design of the through groove 61 ensures that the dividing plate 6 will not be intercepted by the deformed stirring rod 7 when sliding down.

[0046] The top surface of the dividing plate 6 is designed as a funnel, and the diameter of the dividing plate 6 is the same as the inner diameter of the blending cylinder 1 .

[0047] Specifically, the design of low in the middle and high on the sides allows the materials to be discharged from the gap between the deformed stirring rod 7 and the through groove 61 when the conductive wire is de-energized and the materials are discharged after the mixing is completed.

[0048] The insulating rubber sleeve 74 is made of memory elastic rubber of insulating material, and the filling liquid level of the transformer liquid layer 72 in the insulating rubber sleeve 74 is greater than half of the diameter of the rigid round rod 71 when the transformer liquid layer 72 is not powered.

[0049] Specifically, after the conductive wire is de-energized, the transformer liquid layer 72 returns to a liquid state. Since the electromagnetic blocks 73 are de-energized at the same time as the conductive wire is energized, the repulsive force between the electromagnetic blocks 73 disappears. Under the elasticity of the insulating rubber sleeve 74, the insulating rubber sleeve 74 returns to its original shape, and the partition plate 6 loses its support.

[0050] In addition, when the conductive wire is not energized, the liquid level of the transformer liquid layer 72 is located above half of the cross-sectional height of the rigid round rod 71, and the electromagnetic block 73 is arranged on the extension line of the diameter of the rigid round rod 71. When the electromagnetic block 73 is started, the electromagnetic block 73 is still immersed in the transformer liquid layer 72, so that the cross-sectional width of the insulating rubber sleeve 74 in the solidified state after the conductive wire is energized is greater than the cross-sectional width of the through groove 61, so as to provide a better support effect.

[0051] Figure 2-3The drawing shows that a stirring motor 4 is installed on the top of the auxiliary material barrel 2, and the output end of the stirring motor 4 is connected to a stirring rod 41 with a stirring member installed on the surface inside the auxiliary material barrel 2. A discharge pipe 5 is installed through the bottom of the auxiliary material barrel 2, and the tail end of the discharge pipe 5 is connected to the mixing cylinder 1 through a pipe made of an elastic hose. A blocking disc 52 is installed on the inner wall of the discharge pipe 5, and a plurality of discharge channels with rotary valves installed on the surface of the blocking disc 52 are arranged through the interior of the blocking disc 52. The stirring rod 41 passes through the blocking disc 52 and extends to the bottom of the blocking disc 52. The tail end of the stirring rod 41 is connected to a spring bar 53, and the tail end surface of the spring bar 53 is made of magnetic material. An electromagnetic ring 51 that attracts the spring bar 53 is embedded at the bottom end of the inner wall of the discharge pipe 5. The surface of the spring bar 53 slides in contact with the inner wall surface of the discharge pipe 5, and the spring bar 53 is located above the electromagnetic ring 51 when the electromagnetic ring 51 is not energized.

[0052] Specifically, when the stirring motor 4 rotates, it can drive the stirring rod 41 and the stirring member to rotate, mixing the auxiliary materials in the auxiliary material cylinder 2 to prevent accumulation and agglomeration;

[0053] Figure 4-5 It is shown that during quantitative discharging, the rotary valve is opened at a fixed time, and the material is transferred to the inside of the mixing cylinder 1 through the discharge pipe 5 and the pipe made of elastic hose. After the discharge of the auxiliary material cylinder 2 is completed, there may be material residue on the inner wall of the discharge pipe 5. At this time, the stirring motor 4 does not stop rotating, and the stirring rod 41 drives the spring bar 53 to rotate, and at the same time starts the electromagnetic insert ring 51, driving the spring bar 53 to stretch to a position near the bottom of the discharge pipe 5, and under the action of rotation, drives the spring bar 53 to rotate and scrape the inner wall of the discharge pipe 5, and then closes the electromagnetic insert ring 51. Under the elastic action of the spring bar 53 itself, the spring bar 53 will oscillate briefly, which cleans the inner wall of the discharge pipe 5 in the vertical direction, and can vibrate the pipeline, further improving the pipeline residue cleaning effect.

[0054] It also includes a regulation and control system, which is installed on a processor on the top surface of the mixing cylinder 1. The processor is connected to a demand receiving module, a monitoring module, an analysis module and a control module. The monitoring module is connected to the air pressure sensor signal and is used to detect the position height of each dividing plate 6 in the mixing cylinder 1. The control module is connected to the electromagnetic block 73, the electromagnetic ring 81 and the conductive wire signal and is used to control the opening and closing of the electromagnetic block 73, the electromagnetic ring 81 and the conductive wire. The demand receiving module is used to input mixing requirements of different proportions, and the analysis module is used to receive data from the demand receiving module and calculate the different height positions of different dividing plates 6 moving to the surface of the rotating rod 8.

[0055] Specifically, when multiple proportions need to be mixed and blended simultaneously, the mixing proportion of each requirement is input into the demand receiving module, and then the analysis module is used to calculate the space required for each requirement during mixing. According to the inner diameter of the mixing cylinder 1, the space height required for each requirement during mixing is judged, which serves as the basis for the subsequent height positions of multiple dividing plates 6 on the surface of the rotating round rod 8 (when the gap between the dividing plate 6 and the deformed stirring rod 7 closest to the bottom is large, the dividing plate 6 can be adjusted to the position above the previous deformed stirring rod 7, so that the space divided by the dividing plate 6 is larger than the space required for mixing, but does not affect the smooth mixing), and when the height position data of the dividing plate 6 is subsequently adjusted, the monitoring module is used to monitor the displacement state of the dividing plate 6, so that when it moves to the analysis position, the control module starts the electromagnetic ring 81, the electromagnetic block 73 and the conductive wire at the corresponding position.

[0056] Second implementation method:

[0057] Figure 12-13 It is shown that a winding frame 9 is installed on the top of the rotating round rod 8, and the top of the winding frame 9 is connected to the output end of the driving motor 3. An index rope 10 is wound around the surface of the winding frame 9, and one end of the index rope 10 passes through the interior of multiple dividing plates 6.

[0058] The index rope 10 is fixedly connected to the lowermost dividing plate 6 , and the index rope 10 is slidably connected to the other dividing plates 6 .

[0059] Different from the first embodiment, this embodiment improves the recovery of the partition plate 6 to reduce the inconvenience of manual resetting operation.

[0060] Specifically, when resetting the dividing plate 6, the driving motor 3 is started to rotate in the opposite direction (that is, opposite to the rotation direction of the winding rack 9 winding index rope 10), and at the same time, all electromagnetic rings 81 and the conductive wires in all deformed stirring rods 7 and the electromagnetic block 73 are turned off. As the winding rack 9 rotates and reels, the lowest dividing plate 6 is driven to rise (because the lowest dividing plate 6 is fixedly connected to the index rope 10 and is in sliding contact with other dividing plates 6). Since all electromagnetic rings 81 are powered off, the dividing plates 6 above the lowest dividing plate 6 all slide down and accumulate on the surface of the lowest dividing plate 6 under the action of their own weight, driving multiple dividing plates 6 to move up synchronously, thereby realizing the resetting of the dividing plate 6;

[0061] When the dividing plate 6 needs to be released later, the driving motor 3 drives the winding frame 9 to release the index rope 10 to rotate.

[0062] In summary, the present application utilizes a rotary valve to control the discharge amount of auxiliary materials, thereby realizing precise proportional mixing operations, and cooperates with the spring bar 53 in the discharge pipe 5 to realize the residue cleaning operation after discharge, further improving the proportional accuracy during mixing, and when a variety of proportional mixing operations are required, the dividing plate 6, the deformable stirring rod 7 and the electromagnetic ring 81 are utilized to realize flexible segmentation processing of the mixing space in the mixing cylinder 1, so that the present mixing system has a more efficient mixing efficiency and meets a variety of mixing requirements at the same time.

[0063] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
