Description

Technical Field

[0001] The utility model relates to the technical field of chlorinated paraffin production, and specifically to a chlorinated paraffin refining device. Background Art

[0002] Chlorinated paraffin is an organic substance, a chlorinated derivative of paraffin hydrocarbons, with the advantages of low volatility, flame retardancy, good electrical insulation, and low price. It has a wide range of uses and is often used as a flame retardant in industrial fields such as plastics, rubber, and fibers, as well as in the surface treatment of fabrics and packaging materials. Chlorinated paraffin plays an important role in flame retardancy, especially in the production of cable materials, floor materials, hoses, artificial leather, rubber and other products.

[0003] Chlorinated paraffin is usually produced by passing chlorine gas into paraffin to react. However, the initial reaction will contain a large amount of impurities, which need to be refined to improve the purity of the product. The commonly used purification method is to put it into concentrated hydrochloric acid and use its immiscible property with paraffin to purify the crude chlorinated paraffin. At the same time, it can also remove impurities in the crude chlorinated paraffin and make the impurities precipitate to the bottom of the hydrochloric acid. However, in actual production, the precipitation rate is slow. Utility Model Content

[0033] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0034] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0035] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0036] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes a chlorinated paraffin refining device, including: a kettle body 2 is arranged on a bracket 1; a sliding frame 110 is slidably arranged on the bracket 1; there are a plurality of telescopic legs 120, and the sliding frame 110 is hinged on the telescopic legs 120.

[0037] In this embodiment, the support 1 is used to support the sliding frame 110, the kettle body 2 is arranged on the sliding frame 110, and the telescopic leg 120 is used to support the sliding frame 110 and the kettle body 2. When the kettle body 2 is refining chlorinated paraffin, the telescopic leg 120 located on one side of the support 1 will be shortened, so that the sliding frame 110 and the kettle body 2 are tilted at a certain angle, so that the liquid level rotates relative to the bottom surface of the kettle body 2, so that the precipitation can reach the lowest position faster. After the precipitation is completed, the telescopic leg 120 will return to the initial state, so that the original liquid level returns to normal. By tilting the kettle body 2, the precipitation speed of the impurity particles can be significantly increased, the refining time is shortened, and the production efficiency is improved. The telescopic leg 120 adopts a hydraulic cylinder, or it can be a cylinder or other telescopic parts, so that the telescopic leg 120 is more stable when telescopic, preventing the danger caused by insufficient support force, and improving the safety of the refining operation.

[0038] As a further technical solution, there are two sliding frames 110 symmetrically slidably arranged on the bracket 1 , and a plurality of telescopic legs 120 are respectively hinged to the two sliding frames 110 .

[0039] In this embodiment, since the telescopic legs 120 are fixed relative to the ground, when the telescopic legs 120 on one side of the sliding frame 110 descend at the same time, the sliding frame 110 will be driven to slide to adapt to the distance between the telescopic ends of the telescopic legs 120 on both sides, thereby ensuring the normal tilting of the kettle body 2 and improving the safety of the device.

[0040] As a further technical solution, it also includes: there are a plurality of elastic members 130, both ends of the elastic member 130 are arranged on the kettle body 2 and the sliding frame 110, and the elastic member 130 is used to provide a force for the two sliding frames 110 to approach each other.

[0041] In this embodiment, the elastic member 130 is arranged on the telescopic leg 120 and the bracket 1. When the telescopic leg 120 needs to rise after the sedimentation is completed, the weight of the kettle body 2 and the weight of the material are already relatively large resistance. In addition, there is the sliding resistance of the sliding frame 110 itself. Moreover, due to the inclination angle, the rising force may be further dispersed, resulting in the final cylinder force being unable to meet the resetting of the telescopic leg 120, resulting in a locking phenomenon, affecting the normal production process and reducing the production efficiency. The elastic member 130 is arranged between the telescopic leg 120 and the bracket 1. When the telescopic leg 120 rises, the elastic member 130 will pull the sliding frame 110 back, reducing the force required for resetting, preventing the probability of locking, ensuring the progress of production, and improving the production efficiency.

[0042] As a further technical solution, it also includes: the stirring member 210 is rotatably arranged in the kettle body 2; the driving member 220 is arranged outside the kettle body 2, and the driving member 220 is used to drive the stirring member 210 to stir.

[0043] In this embodiment, the stirring member 210 is used to stir the material. When the crude chlorinated paraffin enters the hydrochloric acid, it may rise directly and cannot be fully expanded, resulting in a large amount of impurities contained in the paraffin that cannot be precipitated. The driving member 220 drives the stirring member 210 to stir, which can disperse the paraffin flow, make the paraffin fully contact with the hydrochloric acid, and make all the impurities soluble in hydrochloric acid dissolved in the hydrochloric acid, thereby improving the effect of impurity removal and improving the purity of the chlorinated paraffin.

[0044] As a further technical solution, the stirring member 210 includes: a support tube 230 is arranged in the kettle body 2; a worm 240 is rotatably arranged in the support tube 230, the worm 240 is connected to the driving member 220, and the axis of the worm 240 is parallel to the axis of the kettle body 2; there are several worm wheels 250, which are rotatably arranged on the support tube 230; there are several stirring blades 260, and the stirring blades 260 are arranged on the worm wheel 250.

[0045] In this embodiment, the support tube 230 is arranged at the center of the kettle body 2. The worm 240 drives the worm wheel 250 to rotate, and then drives the stirring blade 260 to rotate. The rotation direction of the stirring blade 260 is perpendicular to the worm 240, so that the worm wheel 250 can drive the hydrochloric acid in the kettle body 2 to further contact with the chlorinated paraffin above, thereby improving the stirring effect and ensuring the purity of the treated material.

[0046] As a further technical solution, the stirring blade 260 includes: a stirring shaft 261 disposed on the worm gear 250; a plurality of paddle blades 262 disposed at intervals on the stirring shaft 261, and the paddle blades 262 are arc-shaped.

[0047] In this embodiment, the worm 240 drives the worm wheel 250 to rotate, and then the paddle 262 rotates through the transmission of the stirring shaft 261, thereby ensuring the stirring effect. The paddle 262 is arc-shaped, and when the paddle 262 rotates, it can stir the liquid level more thoroughly, thereby improving the refining effect.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
