Description

Technical Field

[0001] This utility model relates to the field of PVC processing technology, and in particular to a centrifugal device for processing PVC additives. Background Technology

[0002] Polyvinyl chloride, abbreviated as PVC, is a polymer formed by the polymerization of vinyl chloride monomers under the action of initiators such as peroxides and azo compounds, or under the action of light and heat, according to a free radical polymerization mechanism. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.

[0003] However, pure PVC resin is easily decomposed during processing, has poor fluidity, low impact strength, and poor weather resistance. Therefore, various auxiliary materials need to be added during processing to improve its performance. With the rapid growth of PVC products, a large amount of PVC additives are needed. In the process of mass production of PVC additives, centrifugal dehydration is required. For example, CN219713869U discloses a centrifugal device for PVC processing additives, including a box and a controller, as well as a centrifugal assembly. The centrifugal assembly includes a rotary motor, gear one, rotating column, gear two, centrifuge box, crossbar, support column, roller, annular plate, feed pipe, separation box, screening plate, drain pipe, and collection box. This utility model belongs to the field of PVC processing technology. Specifically, it is a centrifugal device for PVC processing aids that improves the rotation speed of the rotating column and centrifuge box by using gear meshing transmission and a large-diameter gear driving the rotation of a small-diameter gear, thereby improving the efficiency of centrifugal dehydration of PVC additives. Furthermore, it provides limiting support for the centrifuge box during rotation, ensuring its stability. In contrast, this device only uses the rotating column to drive the centrifuge cylinder to rotate, which cannot guarantee the stable rotation of the centrifuge cylinder. Moreover, the sliding connection between the crossbar and the groove results in a certain gap between them after long-term friction, thus failing to guarantee the stability of the centrifuge cylinder rotation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology. By using the synchronous pulley and synchronous belt transmission connection between the transmission rod and the connecting rod, the connecting rod also drives the centrifuge cylinder to rotate, thereby ensuring the stable rotation of the centrifuge cylinder and reducing the occurrence of centrifuge cylinder vibration. This invention provides a centrifugal device for PVC additive processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A centrifugal device for processing PVC additives includes a housing, a centrifugal cylinder inside the housing, the lower end of the centrifugal cylinder being conical, a discharge pipe being threaded through the lower end of the centrifugal cylinder, and a feed pipe being threaded through the upper end of the centrifugal cylinder. The inner wall of the housing is provided with two symmetrically arranged fixing rings, each of which is provided with a connecting mechanism for connecting the centrifugal cylinder. The outer wall of the housing is provided with a driving mechanism for driving the centrifugal cylinder.

[0007] Preferably, the connecting mechanism includes a T-shaped groove formed on the inner wall of the fixing ring, and a plurality of circumferentially arranged T-shaped blocks are disposed through the T-shaped groove, with the ends of the plurality of T-shaped blocks connected to the outer wall of the centrifuge cylinder.

[0008] Preferably, the drive mechanism includes a through groove formed on the outer wall of the housing, a gear is provided through the through groove, and a toothed ring is provided on the outer wall of the centrifuge cylinder, the toothed ring meshing with the gear.

[0009] Preferably, the outer wall of the housing is provided with a support plate, the upper end of the support plate is provided with a power motor, the output shaft of the power motor is provided with a transmission rod, and the gear is provided on the outer wall of the transmission rod.

[0010] Preferably, the centrifuge cylinder is provided with a connecting rod at its upper end, and both the connecting rod and the transmission rod are provided with synchronous pulleys on their outer walls. The two synchronous pulleys are connected by a synchronous belt drive.

[0011] Preferably, the upper and lower ends of the plurality of T-blocks are all connected to ball bearings, and the plurality of ball bearings are all connected to the T-slots in a rolling manner.

[0012] The beneficial effects of this utility model are:

[0013] 1. Through the transmission connection between the transmission rod and the connecting rod via the synchronous pulley and synchronous belt, the connecting rod also drives the centrifuge to rotate, thereby ensuring the stable rotation of the centrifuge and reducing centrifuge vibration.

[0014] 2. By changing the sliding connection between the T-groove and the T-block to a rolling connection, the friction of the centrifuge tube during rotation is reduced, thereby avoiding the instability of rotation caused by high friction. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A centrifugal device for processing PVC additives includes a housing 1, a centrifugal cylinder 2 inside the housing 1, the lower end of the centrifugal cylinder 2 being conical, a discharge pipe 11 being piped through the lower end of the centrifugal cylinder 2, and a feed pipe 3 being piped through the upper end of the centrifugal cylinder 2. The inner wall of the housing 1 is provided with two symmetrically arranged fixing rings 10, and each of the two fixing rings 10 is provided with a connecting mechanism for connecting the centrifugal cylinder 2. The connecting mechanism includes a T-groove 13 formed on the inner wall of the fixing ring 10, and a plurality of circumferentially arranged T-blocks 12 penetrating through the T-groove 13. The ends of the plurality of T-blocks 12 are all connected to the outer wall of the centrifugal cylinder 2.

[0023] The outer wall of the shell 1 is provided with a drive mechanism for driving the centrifuge cylinder 2. The drive mechanism includes a through groove 6 opened on the outer wall of the shell 1, a gear 7 passing through the through groove 6, and a toothed ring on the outer wall of the centrifuge cylinder 2, which meshes with the gear 7.

[0024] The outer wall of the housing 1 is provided with a support plate, the upper end of the support plate is provided with a power motor 5, the output shaft of the power motor 5 is provided with a transmission rod 8, and the gear 7 is provided on the outer wall of the transmission rod 8.

[0025] The centrifuge cylinder 2 is provided with a connecting rod 4 at the upper end. Both the connecting rod 4 and the transmission rod 8 are provided with synchronous pulleys 9 on their outer walls. The two synchronous pulleys 9 are connected by a synchronous belt. Through the transmission connection between the synchronous pulleys 9 and the synchronous belt between the transmission rod 8 and the connecting rod 4, the connecting rod 4 also drives the centrifuge cylinder 2 to rotate, thereby ensuring the stable rotation of the centrifuge cylinder 2 and reducing the occurrence of vibration in the centrifuge cylinder 2.

[0026] Multiple T-blocks 12 are connected to rolling balls 14 at both ends, and multiple rolling balls 14 are connected to rolling T-grooves 13. By changing the sliding connection between T-grooves 13 and T-blocks 12 to a rolling connection, the friction of centrifuge cylinder 2 during rotation is reduced, thereby avoiding the occurrence of rotational instability caused by high friction.

[0027] In use, the additive is placed into the centrifuge cylinder 2 through the feed pipe 3. The power motor 5 is started, which drives the transmission rod 8 to rotate. This causes the gear 7 on the outer wall of the transmission rod 8 to rotate. The meshing of the gear 7 with the gear ring causes the gear ring to rotate, which in turn drives the centrifuge cylinder 2 to rotate. Then, through the transmission connection between the transmission rod 8 and the connecting rod 4 via the synchronous pulley 9 and the synchronous belt, the connecting rod 4 also drives the centrifuge cylinder 2 to rotate (the connecting rod 4 and the gear ring rotate the centrifuge cylinder 2 at the same speed). This ensures the stable rotation of the centrifuge cylinder 2 and reduces the occurrence of vibration in the centrifuge cylinder 2. (Since the centrifuge cylinder 2 is existing technology, its related structure is not described in detail in this figure.)

[0028] By cooperating with multiple T-blocks 12 and multiple T-grooves 13, and by rolling with multiple balls 14 and T-grooves 13, the sliding connection between T-grooves 13 and T-blocks 12 is changed to a rolling connection, thereby reducing the friction of the centrifuge 2 during rotation and avoiding the occurrence of rotational instability caused by high friction.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
