Description

Technical Field

[0001] The utility model relates to the technical field of stabilizer processing equipment, in particular to a processing device for PVC processing stabilizer. Background Art

[0002] In the processing technology of PVC heat stabilizer, the raw materials are made into finished products after steps such as stirring, filter pressing, drying and crushing; among them, the stirring operation is completed in a stirring tank, which requires two-stage stirring processing of rough stirring and fine stirring.

[0003] The existing public patent (publication number CN 205127958 U) discloses a stirring device for processing PVC heat stabilizer, which belongs to the field of heat stabilizer production equipment. It includes two tank-shaped stirring kettles, namely a primary stirring kettle and a secondary stirring kettle, and a stirring device is provided on the stirring kettle; the stirring device includes a stirring motor arranged above the reactor, the stirring motor is connected to a stirring shaft, and a stirring blade is provided at one end of the stirring shaft extending into the stirring kettle; a feeding port is provided at the top of the primary stirring kettle; a first feeding device is provided between the primary stirring kettle and the secondary stirring kettle; and a discharge pipe is provided at the bottom of the secondary stirring kettle. The utility model can control the speed of conveying the feed liquid and improve the feeding efficiency. The overall height of the device using this structure is relatively low, which is convenient for adding raw materials and has low operation risk.

[0004] However, the stirring blades used in the above device are relatively simple. During the rotation of several stirring blades, the raw materials rotate in a fixed direction, which reduces the mixing effect. Therefore, the utility model proposes a processing device for PVC processing stabilizer to improve the above problem. Utility Model Content

[0005] The utility model aims to provide a processing device for PVC processing stabilizer, so as to solve the problems of low practicability and poor stirring effect of the stirring structure in the existing heat stabilizer stirring device proposed in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a processing device for PVC processing stabilizer, comprising a stirring layer arranged vertically and equidistantly; a stirring assembly arranged in a horizontal circular array of the stirring layer, the stirring assembly comprising a mounting bar, a shaft member equidistantly and movably mounted inside the mounting bar, and a grid plate fixed to the bottom of the shaft member, the inner end of the mounting bar is connected to a disc, and a bearing seat is fixed to the upper side of the disc, a kit is sleeved inside the bearing seat, and a drive rod is sleeved inside the kit.

[0007] Preferably, the top end of the driving rod is connected to the output shaft of the driving structure, and the bottom of the driving rod is sleeved with a balance bearing.

[0008] Preferably, the plurality of stirring layers are located inside the stirring tank, and the plurality of stirring layers are parallel to each other.

[0009] Preferably, the disc is a hollow structure, and the disc is connected to the groove at the inner end of the mounting bar via bolts.

[0010] Preferably, the bottom of the grid plate is opened, and the grid plate rotates around the shaft.

[0011] Preferably, adjacent grid plates are spaced apart from each other, and the grid plates are made of metal.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model replaces the existing stirring structure by setting a stirring assembly. The grid plate structure in the stirring assembly can rotate along the shaft while revolving along the driving rod, which can disrupt the fixed mixing direction of the raw materials, so that the raw materials move irregularly in the stirring kettle, thereby improving the mixing effect.

[0014] During specific use, the external driving structure is started. Under the action of the output shaft of the external driving structure, the driving rod drives the bearing seat and the disc to rotate through the kit, and the stirring assembly fixed relative to the disc rotates synchronously. During this process, the mounting bar in the stirring assembly rotates synchronously with the disc, and the grating plate also rotates with the mounting bar under the action of the shaft. However, since the side of the grating plate is constantly in contact with the stabilizer raw material during rotation, the grating plate itself rotates with the shaft as the axis under the damping effect. That is, driven by the driving structure, the grating plate as a whole revolves along the driving rod while the grating plate itself rotates with the shaft as the axis, and the rotation states of several grating plates are different due to different forces. At the same time, the grating plate is a vertical structure, so the contact area with the raw material is large, and the raw materials inside the stirring tank can also be fully mixed up and down.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figure 1-3 , in the figure: This embodiment is a preferred implementation of the technical solution, a processing device for PVC processing stabilizer, comprising a stirring layer arranged vertically and equidistantly; a stirring assembly 6 arranged in a horizontal circumferential array of the stirring layer, the stirring assembly 6 comprising a mounting bar 61, a shaft 62 equidistantly mounted inside the mounting bar 61 and a grid plate 63 fixed to the bottom of the shaft 62, the inner end of the mounting bar 61 is connected to a disc 4, and a bearing seat 3 is fixed to the upper side of the disc 4, the bearing seat 3 is internally sleeved with a set 2, and the set 2 is internally sleeved with a driving rod 1;

[0022] It should be noted that: in the processing device of the PVC processing stabilizer involved in the present application, the raw materials are mainly stirred by the stirring structure, which facilitates the subsequent steps of filter pressing, drying and crushing. In the stirring process, the stirring operation is completed in the stirring kettle, which needs to undergo two-stage stirring processing of rough stirring and fine stirring. The stirring structure in the present application replaces the stirring structure in the traditional stirring kettle, and the grid plate 63 in the stirring assembly 6 is responsible for stirring the raw materials. While the grid plates 63 increase the mixing area, the independent rotation of each grid plate 63 can disrupt the mixing trajectory of the raw materials, so that the raw materials are mixed more fully;

[0023] In specific use, first, the spacing of the stirring layer is adjusted, and the whole structure is installed in the stirring kettle. When the raw material is stirred, the external driving structure is started. Under the action of the output shaft of the external driving structure, the driving rod 1 drives the bearing seat 3 and the disc 4 to rotate through the kit 2, and the stirring assembly 6 fixed relatively to the disc 4 rotates synchronously. In this process, the mounting bar 61 in the stirring assembly 6 keeps rotating synchronously with the disc 4, and the grid plate 63 also rotates with the mounting bar 61 under the action of the shaft 62. However, since the side of the grid plate 63 is constantly in contact with the stabilizer raw material during the rotation process, under the damping effect of the shaft 62, the grid plate 63 itself rotates with the shaft 62 as the axis, that is, through the drive of the driving structure, the grid plate 63 as a whole revolves along the driving rod 1, and the grid plate 63 itself rotates with the shaft 62 as the axis, and the grid plates 63 are subjected to different forces, resulting in different rotation states. Therefore, the fixed mixing direction of the raw materials can be disrupted, so that the raw materials move irregularly in the stirring kettle, thereby improving the mixing effect.

[0024] Among them Figure 1 As shown, the top end of the driving rod 1 is connected to the output shaft of the driving structure, and the bottom of the driving rod 1 is sleeved with a balance bearing 5; the plurality of stirring layers are located inside the stirring tank, and the plurality of stirring layers are parallel to each other;

[0025] It should be noted that the driving rod 1 rotates under the transmission action of the output shaft of the external driving structure (generally a motor), and the balancing bearing 5 arranged at the bottom of the driving rod 1 is used to balance its rotational motion to avoid strong shaking. During installation, the balancing bearing 5 requires auxiliary fixation with an external mounting structure. This application does not make further restrictive descriptions. At the same time, the stirring structure involved in this application is used in combination with an external stirring kettle for mixing and stirring the stabilizer.

[0026] Among them Figure 2 and Figure 3 As shown, the disc 4 is a hollow structure, and the disc 4 is connected to the groove at the inner end of the mounting bar 61 through bolts; the bottom of the grid plate 63 is open, and the grid plate 63 rotates around the shaft 62; adjacent grid plates 63 are spaced apart from each other, and the grid plates 63 are made of metal;

[0027] It should be noted that the hollow structure of the disk 4 facilitates the installation of the mounting strip 61. In order to increase the uniformity of stirring, the mounting strip 61 fixed to the same disk 4 is equidistantly arranged, and the outer edge of the mounting strip 61 is as close to the inner wall of the stirring kettle as possible. The grid plate 63 is a plate structure as a whole, and is made of metal material, which can increase its own structural stability and avoid bending deformation due to long-term stirring. The bottom opening of the grid plate 63 can prevent the powdered stabilizer from accumulating in the groove of the grid plate 63. When the mounting strip 61 rotates, it drives the grid plate 63 to rotate synchronously. Since the grid plate 63 itself is affected by the damping of the stabilizer, the grid plate 63 rotates with the shaft 62 as the axis, which is used to stabilize the stabilizer. Stirring is performed. At the same time, the edges of the adjacent grating plates 63 do not touch each other during the rotation process to avoid motion interference. The rotational motion of the grating plates 63 is divided into two types. One is that under the action of the connecting structures such as the shaft 62, the mounting bar 61, the disc 4, the bearing seat 3 and the kit 2, the grating plates 63 and the driving rod 1 keep rotating in the same direction. The second is that under the damping action of the raw materials inside the stirring kettle, the grating plates 63 rotate around the shaft 62 as the axis, and the raw materials will be turned over during the process. The above two circular motions are combined to form the motion trajectory of the grating plates 63. At the same time, the grating plates 63 are vertical structures, so that the contact area with the raw materials is large, and the raw materials inside the stirring kettle can also be fully mixed up and down.

[0028] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make some simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
