In addition, the temperature condition is also an important factor affecting the mixing quality. When the mixing environment is at a relatively low temperature, especially in cold regions in the north, or when certain materials need to be mixed under specific temperature conditions to ensure the best effect, the existing mixers often cannot meet these requirements.

[0041] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0042] As Figures 1 to 5 shown, the present solution discloses a special mixer for tar residue, including: a mixing chamber 1, a top cover plate, a cutting unit, and a power unit;

[0043] The mixing chamber 1 has an open top, and the top cover plate is detachably arranged at the open part. A mixing wing 7 is arranged inside the mixing chamber 1; a feed inlet is arranged on the top cover plate, and the cutting unit is arranged at the feed inlet part to pre-cut the material passing through the feed inlet. The cutting unit includes a scraper 81; the power unit drives the mixing wing 7 and the scraper 81 to rotate. The power output end of the driving motor 4 is connected to the transmission shaft 6 through a speed reducer 5, and the mixing wing 7 is connected to the transmission shaft 6;

[0044] Among them, the drive motor 4 drives the stirring fins 7 to rotate through the transmission shaft 6. There is at least one stirring fin 7, and the installation height of the stirring fin 7 in the stirring bin 1 can be set according to the actual situation. When there is a stirring fin 7 at the position near the bottom of the stirring bin 1 below the transmission shaft 6, on the one hand, the stirring fin 7 here can play a stirring role, and at the same time, it also plays a certain auxiliary role in the discharging of the discharge port 104. The discharge port 104 is arranged on the bottom plate 101 of the bottom of the stirring bin 1. The surrounding part of the discharge port 104 of the bottom plate 101 can be set as a funnel-shaped structure convenient for the material to flow out according to the actual use requirements. At the same time, structures such as a suction pump for auxiliary discharging can be arranged at the discharge port 104 according to the different materials actually stirred. At the same time, a blocking structure such as a valve or a valve plate for controlling the opening and closing of the discharge port 104 is arranged at the discharge port 104;

[0045] During the process of the drive motor 4 driving the stirring fins 7 to move through the transmission shaft 6, the scraper fixing member 8 is also used to drive the scraper 81 to rotate. The scraper 81 is arranged on both sides of the scraper fixing member 8. One side of the scraper 81 has a blade 811. At the same time, the feeding port part includes a feeding cylinder 14, and the stirring bin 1 is fed through the feeding cylinder 14. A horizontal groove 141 convenient for the scraper 81 to pass through is arranged on the feeding cylinder 14. The scraper 81 rotates with the transmission shaft 6, and the blade 811 part of the scraper 81 is used to assist in cutting the material in the feeding cylinder 14. It should be noted that the function of cutting with the scraper 81 in this solution is to cut the large pieces of material doped in the feed as much as possible through the scraper 81, so as to improve the subsequent stirring effect. At the same time, in order to simplify the structure of the mixer, the scraper 81 and the stirring fins 7 adopt a set of power units. Therefore, when the actual stirring requirements of the stirring fins 7 are met, the rotation speed of the drive motor 4 can be increased as much as possible to increase the contact probability between the scraper 81 and the material, thereby improving the stirring effect. Therefore, through the setting of the scraper 81 in this solution, the number of large pieces of material falling into the stirring bin 1 can be reduced. At the same time, for the situation where the existing large pieces of material are stuck at the feeding port part, the material stuck in the feeding cylinder 14 can also be chopped by the scraper 81 in this solution, so that the material can fall smoothly into the stirring bin 1;

[0046] At the same time, for the possible need to heat the stirring bin 1 during the existing stirring process, this solution mainly includes two aspects. On the one hand, a heating pipe 9 is arranged to heat the side wall of the stirring bin 1 with hot water in the boiler as the heating medium. On the other hand, a tracing pipe 10 is arranged at the bottom of the stirring bin 1, and the medium with residual heat generated by other components in the production process is used as the tracing medium to provide tracing heat for the bottom of the stirring bin 1. The specific problem of adopting heating and / or tracing or heating is adjusted according to the actual needs. Specifically:

[0047] The outer wall of the mixing bin 1 is provided with a heat preservation layer 103, and a heating space is formed between the heat preservation layer 103 and the outer wall of the mixing bin 1;

[0048] A heating pipe 9 is arranged in the heating space. The heating pipe 9 is of a coil structure and is wound around the outer wall of the mixing bin 1;

[0049] The water inlet 91 of the heating pipe 9 is located below the water outlet 92.

[0050] A tracing pipe 10 is arranged below the bottom plate 101 of the mixing bin to heat the mixing bin 1 by using a tracing medium. A tracing support 102 for fixing the tracing pipe 10 is arranged below the bottom plate 101 of the mixing bin 1.

[0051] Meanwhile, in order to facilitate the cleaning of the mixing bin 1, the cover plate is set to be a structure that is easy to disassemble as a whole. The top cover plate includes a first top plate 2 and a second top plate 3. There are two second top plates 3, and the two second top plates 3 are semi-circular. The first top plate 2 is arranged between the two second top plates 3; a flange is arranged on the edge of the first top plate 2 and is erected on the edge of the open part of the mixing bin 1 by using the flange. The power unit is installed on the first top plate 2.

[0052] Meanwhile, according to the existing requirement of injecting water or other liquids into the mixing bin 1 during the mixing process, a water injection port 112 is arranged on the first top plate 2, and the water injection pump 11 is connected to the water injection port 112 through a water injection pipe 111.

[0053] Meanwhile, a temperature sensor connection port 12 and a pressure transmitter connection port 13 are arranged on the mixing bin 1 of this solution for configuring components such as a temperature sensor and a pressure sensor according to actual requirements.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
