Description

Technical Field

[0001] The utility model belongs to the technical field of tar separation, and particularly relates to a tar separation device. Background Technique

[0002] Coal tar is a black or dark brown viscous liquid with a pungent odor generated during the carbonization of coal. Coal tar can be divided into low-temperature coal tar, medium-temperature coal tar, and high-temperature coal tar according to the carbonization temperature. The coal tar obtained in coke production belongs to high-temperature coal tar. It is one of the purified products of coke oven gas condensed and separated during the cooling process of raw gas. During industrial production, waste tar will be generated. However, since a large amount of water is also used during industrial production, a large amount of water and tar are dumped and discharged together, resulting in the discharge of waste water and tar to the same place, so that the tar will contain moisture. In order to separate and reuse the tar and the water liquid, a separation device is needed. Most of the existing separation devices are used to extract gas from coal tar and cannot separate the water liquid from the tar.

[0003] A coal tar separator with the publication number of CN221296813U supplies raw gas through a tangentially connected raw gas inlet pipe with a valve. The raw gas spirally rises along the inner wall of the detachable housing. The rising raw gas first encounters a detachable oil absorption structure to absorb tar, and then the first detachable barrier structure is used to slow down the rising speed of the raw gas and prevent the refluxed raw gas from being absorbed by oil for the second time. The raw gas encounters a detachable water absorption structure to absorb moisture. After being absorbed by water, the raw gas rises and encounters the second detachable barrier structure, and the rising speed of the raw gas is slowed down again, and the refluxed raw gas is prevented from being absorbed by water for the second time. Finally, the gas is discharged from the gas discharge pipe to ensure the purity of the obtained gas. However, it cannot conveniently separate the moisture contained in the tar, which will increase the extraction difficulty and reduce the efficiency during the extraction process. The present application designs a separation device for separating the water liquid in the front to obtain purer tar and then performing separation and extraction, which helps to increase the subsequent extraction efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tar separation device to solve the problems raised in the background technique.

[0005] To achieve the above object, the present utility model provides the following technical solution: A tar separation device, comprising a separation tank, wherein a plurality of support columns are provided at the bottom of the separation tank, and the top of the separation tank is open and provided with a capping. An outer ring plate is provided inside the separation tank, and a connecting plate is connected between the outer periphery of the outer ring plate and the inner wall of the separation tank. A filter baffle is embedded in the lower half of the outer periphery of the outer ring plate, and a rotating rod is provided at the center of the outer ring plate. A plurality of stirring blades are connected to the outer periphery of the rotating rod. Inner concave portions are provided at both the top end and the bottom end of the outer ring plate, and telescopic outer sleeves capable of telescoping are provided in the inner concave portions. A threaded rod for driving its telescoping is provided on the telescopic outer sleeve.

[0006] In a further embodiment, a supplementary material port is installed on the top of the capping, and a tar inlet is provided on one side of the supplementary material port.

[0007] In a further embodiment, a plurality of inner cavities are provided in the central region of the outer ring plate, and a driving active gear and two driven gears for transmission are provided inside the inner cavities.

[0008] In a further embodiment, the outer periphery of the threaded rod is threadedly connected to the telescopic outer sleeve, and the end of the threaded rod is rotatably connected to the outer ring plate.

[0009] In a further embodiment, one end of the threaded rod is of a penetrating design, and the penetrating end of the threaded rod is connected to the corresponding driven gear.

[0010] In a further embodiment, a driving motor is installed on the outer periphery of the separation tank, and the driving end of the driving motor penetrates the separation tank and is connected to a driving rod through a coupling.

[0011] In a further embodiment, the end of the driving rod is connected to the center of the active gear, and the active gear meshes with the corresponding driven gear.

[0012] In a further embodiment, an arc cover is provided on the outer side of the inner cavity, and the arc cover is of a detachable design.

[0013] In a further embodiment, an observation window for easy observation is embedded on the outer periphery of the separation tank, and the outer ring plate is designed with a transparent material.

[0014] In a further embodiment, a discharge port is installed at the bottom of the separation tank, and the discharge port is located at the tangent point position of the edge of the outer ring plate.

[0015] Compared with the prior art, the technical effects and advantages of the present utility model:

[0016] The central design of the rotating rod and the connection design between the rotating rod and multiple stirring blades, through the shielding design of the middle area of the outer ring plate and the rotation of the stirring blades, can further stir the tar to generate eddy currents. During the design of the external baffle plate of the outer ring plate and the cyclic transportation process of the eddy current force, impurities can be filtered;

[0017] After carbon tetrachloride is added, due to the design of the eddy current and the gap design at the upper and lower ends of the outer ring plate, liquid can be attracted from the bottom, discharged to the outside through the upper gap, and then enter from the bottom, thus realizing internal circulation to achieve uniform mixing. Since tar dissolves in carbon tetrachloride, after adding carbon tetrachloride, it will be stratified. The colored layer is carbon tetrachloride containing oil, realizing the separation of tar and water liquid;

[0018] When the separation is generally completed, the connection design between the driving motor and the driving rod and the connection between the driving rod and the driving gear, through the meshing design between the driving gear and the driven gear and the connection between the driven gear and the threaded rod, and in cooperation with the threaded connection between the threaded rod and the telescopic outer sleeve, can further enable the telescopic outer sleeve to seal the gaps at the top and bottom. At this time, with the rotation design of the stirring blades, circulation will not be realized. Through stirring, internal stirring can be achieved. In combination with the different densities of substances, complete separation can be realized, and then through the discharge port, tar can be discharged;

[0019] This tar separation device can uniformly mix carbon tetrachloride, water liquid and tar in internal circulation, assist in rapid reaction to achieve separation, and then through the design of upper and lower discharging, the discharge of tar and water liquid can be realized.

[0029] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features are not described.

[0030] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figures shown in the present utility model, and are hereby explained together.

[0031] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0032] Most of the existing separation devices are used to extract gas from coal tar and cannot separate the water liquid from the tar. During the factory production process, generally, the water liquid and tar of the waste gas are poured and discharged together. Therefore, the tar contains a large amount of water, which increases the difficulty and reduces the efficiency of the extraction process. In view of this, a separation device for tar and water liquid with a simple structure is designed for pretreatment. After separating the water liquid, the content of the tar is purer and the extraction time will be reduced a lot. In view of this, a new type of separation device is designed, and the specific structure is as follows.

[0033] Water is insoluble in carbon tetrachloride, and tar is soluble in carbon tetrachloride. After adding carbon tetrachloride, it will be layered, and the colored layer is carbon tetrachloride containing oil

[0034] Please refer to Figures 1 to 5, The tar separation device includes a separation tank 1, multiple support columns 2, and a capping 3. The tops of the multiple support columns 2 are fixed to the bottom of the separation tank 1 and are designed to be distributed in an array. A connection block is provided at the bottom of the support column 2, and a screw hole is provided at the bottom of the connection block. The screw hole is fixed to the ground through a fastener. The top of the separation tank 1 is open, and the top of the opening is connected to the capping 3 by bolts. An auxiliary material port 5 is installed on the top of the capping 3. The auxiliary material port 5 is used to input carbon tetrachloride, and a tar inlet 6 is provided on one side of the auxiliary material port 5.

[0035] Please refer to Figures 1 to 4 , To achieve the design of internal circulation, an outer ring plate 10 is provided inside the separation tank 1. A connecting plate 11 is connected between the outer periphery of the outer ring plate 10 and the inner wall of the separation tank 1. The connecting plate 11 is used to fix the position of the outer ring plate 10.

[0036] A rotating motor 7 is installed at the center of the bottom of the separation tank 1. The driving end of the rotating motor 7 penetrates the separation tank 1 and is connected to a rotating rod 8 through a coupling. A plurality of stirring blades 9 are connected to the outer periphery of the rotating rod 8. There are circulating gaps between the upper and lower ends of the outer ring plate 10 and the separation tank 1, and a reflux channel is formed between the outer side of the outer ring plate 10 and the separation tank 1.

[0037] Please refer to Figure 1 and Figure 2 , To filter impurities, a filtering baffle 13 is embedded in the lower half of the outer periphery of the outer ring plate 10. When tar is input, during the circulating process of the eddy current, the tar can be filtered through the filtering baffle 13 to filter impurities.

[0038] Please refer to Figure 1 and Figure 2 , To facilitate observation, an observation window 4 for easy observation is embedded on the outer periphery of the separation tank 1. The outer ring plate 10 is designed with a transparent material. Through the transparent design of the outer ring plate 10, the internal observation can be strengthened, and it is convenient to master the separation situation.

[0039] Please refer to Figures 1 to 5 , To achieve stirring and separation, concave parts are provided at both the top and bottom of the outer ring plate 10. Telescopic outer sleeves 12 that can be telescoped are provided in the concave parts, and threaded long openings are provided on the telescopic outer sleeves 12;

[0040] A plurality of inner cavities 15 are provided in the central area of the outer ring plate 10. An arc cover 16 is provided on the outer side of the inner cavity 15. The arc cover 16 is designed to be detachable. A driving motor 25 is installed on the outer periphery of the separation tank 1. The driving end of the driving motor 25 penetrates the separation tank 1 and the arc cover 16 and is connected to a driving rod 24 through a coupling;

[0041] The end of the drive rod 24 is connected with a driving gear 23. Two driven gears 22 are meshed with the outer periphery of the driving gear 23. One side of the two driven gears 22 is connected with a threaded rod 21. The threaded rod 21 is rotationally connected with the outer ring plate 10, and the threaded rod 21 is threadedly connected with the inner periphery of the threaded long opening.

[0042] In order to achieve discharging, a discharge port 14 is installed at the bottom of the separation tank 1. The discharge port 14 is located at the tangent point of the edge of the outer ring plate 10. This design is to discharge the tar inside and outside the outer ring plate 10 simultaneously. An outlet for discharging the water liquid is provided in the upper half of the outer side of the separation tank 1 and is communicated with the inside.

[0043] The lifting structure can be an electric device such as a hydraulic rod or a telescopic rod. Although using an electric device can play a role in lifting, since the telescopic movement of an electric device such as a hydraulic rod or a telescopic rod requires a certain amount of telescopic space margin. For example, if it is a hydraulic rod, enough space must be reserved at the bottom to store the length of the fixed part of the hydraulic rod, which leads to waste of space. And the lifting structure of this design is surrounded by liquid inside, so the existing electric lifting structure is not applicable to this design. For this point, another lifting structure is designed.

[0044] The above components and electrical equipment are all existing technologies or technologies that can be realized currently. Their working principles, dimensions and models have nothing to do with the functions of this application, so no more description will be made, and they are all controlled by a remote control switch.

[0045] Working Principle

[0046] When this tar separation device is needed to be used, the tar is input into the inside of the separation tank 1 through the tar inlet 6, and carbon tetrachloride is input through the auxiliary material port 5. The rotary motor 7 is started to drive the rotary rod 8 to rotate, so that the stirring blades 9 stir the inside to generate a vortex force.

[0047] It can realize the suction of the liquid from the bottom, discharge it to the outside through the upper gap, and then enter from the bottom, thereby realizing the internal circulation to achieve uniform mixing. During the internal circulation process, impurities will be filtered by the filter plate 13.

[0048] After the mixing is generally completed through the observation window 4, the driving motor 25 is started to drive the driving gear 23 to rotate, so that the driven gears 22 rotate, causing the threaded rod 21 to rotate, further enabling the telescopic outer sleeve 12 to block the upper and lower gaps, stopping the internal circulation. The stirring blades 9 continue to stir. Under the condition of the rotational force, the heavier substances will precipitate to the lower layer, further realizing stratification, and then can be discharged through the discharge port 14.
