Description

Technical Field

[0001] The utility model relates to the technical field of tire oil refining, in particular to a slag discharging device. Background Art

[0002] Traditional rear-end dischargers utilize an eccentric, solid-shaft spiral tube design. The tube measures 420 mm and the spiral blades measure 300 mm. The lower portion of the spiral blades, in contact with the tube, is suspended above the tube. This suspended portion allows for the passage of oil and gas, while the ash passes through the lower portion. A ball valve is connected below the discharge port. This process creates a recessed area between the upper sealing surface of the ball valve and the spiral tube. Residual oil accumulates in this recess, along with some at the bottom of the spiral tube. This residual oil must be cleaned out before safe discharge. The viscous and high temperature of the residual oil make it difficult to safely handle. The accumulation of residual oil in both the recessed area and the bottom of the spiral tube is difficult to handle and poses a potential risk during discharge. Furthermore, dust from the ash can clog the outlet during discharge.

[0003] A Chinese utility model, published on May 10, 2022, with publication number CN 216473079 U, discloses a drum discharge device for waste tire oil refining equipment. This device, belonging to the field of waste tire oil refining technology, comprises a first spiral discharge device connected to the discharge port of a reactor, and a drum slag bin. The drum slag bin comprises an inner cylinder and an outer cylinder, with a cavity formed between the inner and outer cylinders and meshed in the inner cylinder. A second spiral discharge device is connected to the inner cylinder, and a third spiral discharge device is connected to the cavity of the outer cylinder. The second spiral discharge device is connected to the first spiral discharge device. The second spiral discharge device is provided with an outlet for steel balls, and the third spiral discharge device is provided with an outlet for carbon black. However, the residual oil in the first, second, and third spiral discharge devices of this utility model patent easily accumulates and is difficult to handle. Summary of the Invention

[0004] In view of the above technical problems, the present invention proposes a slag discharge device for waste tire oil refining equipment, which is used to solve the problem that the residual oil in the slag discharge device of the oil refining equipment in the prior art is easy to accumulate and difficult to handle.

[0005] In order to achieve the above object, the technical solution of the utility model is achieved as follows:

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, a slag discharge device for a waste tire oil refining device as described in Example 1 of the present invention includes an outer shell 4 and a slag discharge conveying mechanism arranged on the outer shell 4. The outer shell 4 is provided with an air outlet 6 on the upper side and a slag discharge port 2 on the lower side. A movable inner shell 3 is provided inside the outer shell 4. The inner shell 3 is coaxially arranged with the outer shell 4, and the outer wall of the inner shell 3 is in contact with the inner wall of the outer shell 4. The inner shell 3 is provided with an opening that can be aligned and communicated with the air outlet 6 or the slag discharge port 2. In this embodiment, the opening includes an inner air outlet corresponding to the air outlet 6. The inner shell 3 is respectively provided with an air outlet sealing portion for sealing the air outlet 6 and a slag discharge sealing portion for sealing the slag discharge port 2. The air outlet sealing portion and the inner air outlet are arranged on the upper side of the inner shell 3 and are arranged front and back along the axial direction of the inner shell 3. The slag discharge sealing portion is provided on the lower side of the inner shell 3 and can correspond to the slag discharge port 2. The movement of the inner shell 3 can align the inner gas outlet of the inner shell 3 with the gas outlet 6 to open the gas outlet 6, and at the same time the slag sealing part closes the slag outlet 2, or the gas sealing part closes the gas outlet 6 to open the slag outlet 2.

[0030] Furthermore, the outer shell 4 is provided with a moving drive member for pushing the movement of the inner shell 3 so that the inner shell 3 opens one of the gas outlet 6 and the slag outlet 2 and closes the other, thereby achieving better control.

[0031] Furthermore, since the oil and gas discharge stage and the ash and slag discharge stage of the waste tire refining equipment are not carried out simultaneously, the oil and gas are discharged first, and the ash and slag can be discharged only after the oil and gas are discharged. Therefore, in this embodiment, the inner shell 3 mainly has two stop positions. Figure 1 The figure shows the oil and gas discharge stage. The inner shell stops at this position. The inner gas outlet of the inner shell 3 is aligned with the gas outlet 6 of the outer shell 4, so that the oil and gas can flow out from this outlet. At this time, the slag discharge sealing part closes the slag discharge port 2 of the outer shell 4, and the oil and gas cannot pass through and cannot be deposited here. When the oil and gas are finished, the inner shell 3 is controlled by the moving drive member to move to another stop position, such as Figure 2As shown, the air outlet sealing portion of the inner housing 3 seals the air outlet 6 of the outer housing 4. At this point, the inner housing 3 is offset from the slag outlet 2, allowing the inner side of the slag outlet 2 to be fully open, allowing ash and slag to be discharged. Since the air outlet is closed, dust from the slag flying into the air outlet is prevented from clogging it and affecting the operation of the equipment.

[0032] Example 2 is different from Example 1 in that Figure 1 and Figure 2 As shown, the outer shell 4 is further provided with a maintenance opening 7. The movable driving member is provided on the side wall of the maintenance opening 7.

[0033] Furthermore, the movable driving member is a telescopic driving member 9, the fixed end of the telescopic driving member 9 is fixedly connected to the side wall of the maintenance port 7, the telescopic end of the telescopic driving member 9 is connected to the inner shell 3, and the telescopic direction of the telescopic end is parallel to the axial direction of the outer shell 4 and the inner shell 3.

[0034] In this embodiment, the fixed end of the telescopic drive member 9 is fixed to the outside of the side wall of the maintenance opening 7, while the telescopic end of the telescopic drive member 9 is inserted through the side wall of the maintenance opening 7 and slides with the side wall of the maintenance opening 7. In this embodiment, a sliding seal is provided between the telescopic end and the side wall of the maintenance opening 7 to ensure a seal between the telescopic drive member 9 and the side wall of the maintenance opening 7. The sliding seal adopts a structure known from the prior art. In another embodiment, the fixed end of the telescopic drive member 9 is inserted through the side wall of the maintenance opening 7 and is fixed thereto, with the telescopic end located completely inside the maintenance opening 7.

[0035] Furthermore, the end of the telescopic end, remote from the fixed end, is connected to the inner housing 3 via a connector 8. The specific structure of connector 8 is not limited and can be made of steel plates or other steel components as needed, as long as it can stably connect the telescopic end of the telescopic drive member 9 to the inner housing 3. Connector 8 can be welded to the inner housing 3 and the telescopic end of the telescopic drive member 9, or it can be bolted.

[0036] Example 3 is different from Example 2 in that Figure 1 As shown, the telescopic driving member 9 is a hydraulic cylinder or a hydraulic rod or an electric push rod. In this embodiment, the telescopic driving member 9 adopts a hydraulic cylinder.

[0037] Example 4 is different from Example 1 in that Figure 1 and Figure 2 As shown, the slag conveying mechanism is a shaftless spiral tube conveying mechanism. A cavity is formed in the center of the spiral, and the spiral can pass oil and gas as well as convey ash and slag.

[0038] Specifically, the shaftless spiral tube conveying mechanism includes a spiral blade 5 disposed within an outer shell 4 and a forward / reverse drive motor 1 for driving the spiral blade 5. The forward / reverse drive motor 1 is fixed to one end of the outer shell 4. The output shaft of the forward / reverse drive motor 1 extends into the outer shell 4 and connects to one end of the spiral blade 5. When residual oil is deposited at the bottom of the spiral tube, the forward / reverse drive motor 1 activates the spiral reversal function to push the residual oil at the bottom of the spiral tube back into the reactor.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that any modification to the technical solutions described in the aforementioned embodiments, or any equivalent replacement of some or all of the technical features thereof, within the spirit and principles of the present invention, does not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and should all be included in the scope of protection of the present invention.
