Description

Technical Field

[0001] This utility model relates to the field of oil shale dry distillation technology; more specifically, it relates to an oil shale dry distillation feeder. Background Technology

[0002] Oil shale dry distillation is a high-temperature pyrolysis process. Under air-free or oxygen-deficient conditions, oil shale is heated, causing the solid organic matter in the shale to thermally decompose, generating a mixture of gaseous, liquid, and aerosol hydrocarbons. After collection by a condensation system, shale oil, similar to crude oil, can be produced. The dry distillate can be further processed into fuel oil or chemical feedstock. This technology aims to extract liquid fuels from unconventional oil and gas resources.

[0003] The oil shale retorting feeder is a key feeding device for the retorting furnace. It is mainly responsible for conveying small-sized blocky oil shale to the high-temperature retorting furnace. Stable feeding is crucial for maintaining the thermal balance and product quality during the retorting process.

[0004] Currently, existing technologies for the dry distillation of oil shale face several challenges. Continuous feeding is required during the distillation process, but the heavy weight and varying particle sizes of lumpy oil shale make transportation difficult and hinder control over flow rate. This reduces the equipment's practicality. Furthermore, different feeders often have different connection specifications to the feed inlets of different dry distillation furnaces, leading to connection difficulties and potential issues with insufficient sealing. Therefore, a dedicated oil shale dry distillation feeder is urgently needed to address these problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an oil shale dry distillation feeder to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an oil shale dry distillation feeder, comprising:

[0007] A connecting pipe is provided with a transmission structure at its lower end, and a connecting structure is provided at the lower end of one end of the transmission structure; the transmission structure includes a transmission pipe, a motor, a baffle, a rotating rod, and a spiral plate, and the transmission pipe is fixedly connected to the outer surface of the lower end of the connecting pipe; the connecting structure includes a connecting plate, an adjusting hole, a bolt, and a nut, and the connecting plate is fixedly connected to the outer surface of the lower end of one end of the transmission pipe.

[0008] Preferably, the motor is installed inside the other end of the transmission tube, the baffle is fixedly connected inside the transmission tube at the inner end of the motor, the rotating rod is inserted inside the transmission tube, and a spiral plate is fixedly connected to the outer surface of the rotating rod. This design allows the rotating rod and the spiral plate to rotate inside the transmission tube.

[0009] Preferably, the output end of the motor is fixedly connected to the outer surface of one end of the rotating rod, the external dimensions of the baffle are adapted to the internal dimensions of the transmission tube, and the internal dimensions of the baffle are adapted to the external dimensions of the rotating rod. This design allows the rotating rod to rotate by starting the motor.

[0010] Preferably, the spiral plate is spiral-shaped, and the external dimensions of the spiral plate are adapted to the internal dimensions of the transmission tube. This design makes the spiral plate more stable when rotating inside the transmission tube.

[0011] Preferably, the adjustment holes are provided in multiple sets, and the multiple sets of adjustment holes are respectively opened inside the outer surface of the connecting plate. Bolts are engaged inside the multiple sets of adjustment holes, and nuts are threaded to the outer surface of the lower end of the bolts. This design allows the bolts to move inside the adjustment holes.

[0012] Preferably, multiple sets of adjustment holes are evenly distributed inside the outer surface of the connecting disc, and the external dimensions of the bolt are adapted to the internal dimensions of the adjustment holes. This design makes the bolt more stable when moving inside the adjustment holes.

[0013] The technical effects and advantages of this utility model are as follows: By starting the motor, the rotating rod can be rotated, which in turn drives the spiral plate to rotate, thus enabling the blocky oil shale inside the transmission pipe to be continuously transported outward. At the same time, the rotation speed of the spiral plate can be controlled by controlling the motor, which facilitates the control of the oil shale transmission speed and avoids the situation of poor oil shale transmission effect, thereby improving the practicality of the equipment to a certain extent.

[0014] By attaching the connecting plate to the connecting device at the feed inlet of the distillation furnace, and moving the bolt to the appropriate position inside the adjusting hole according to the specifications of the feed inlet connecting device, and then rotating the nut to connect and tighten the nut to the outer surface of the bolt, it is possible to quickly connect to distillation furnaces of different specifications, which improves the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The oil shale dry distillation involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1, as Figures 1 to 3 As shown, this embodiment proposes a feeder for oil shale retorting, including:

[0022] Connecting pipe 1, the lower end of connecting pipe 1 is provided with transmission structure 2, and the lower end of one end of transmission structure 2 is provided with connecting structure 3;

[0023] The transmission structure 2 includes a transmission pipe 21, a motor 22, a baffle 23, a rotating rod 24, and a spiral plate 25. The transmission pipe 21 is fixedly connected to the outer surface of the lower end of the connecting pipe 1. The motor 22 is installed inside the other end of the transmission pipe 21. The baffle 23 is fixedly connected inside the transmission pipe 21 at the inner end of the motor 22. The rotating rod 24 is inserted inside the transmission pipe 21. The output end of the motor 22 is fixedly connected to the outer surface of one end of the rotating rod 24. The external dimensions of the baffle 23 are adapted to the internal dimensions of the transmission pipe 21, and the internal dimensions of the baffle 23 are adapted to the external dimensions of the rotating rod 24. This design allows the rotating rod 24 to rotate by starting the motor 22, which in turn drives the spiral plate 25 to rotate. At the same time, the rotating rod 24 is more stable when rotating inside the baffle 23. The baffle 23 also prevents oil shale fragments from entering the motor 22 and damaging it.

[0024] Furthermore, a spiral plate 25 is fixedly connected to the outer surface of the rotating rod 24. The spiral plate 25 is spiral in shape, and the external dimensions of the spiral plate 25 are adapted to the internal dimensions of the transmission pipe 21. This design allows the spiral plate 25 to rotate synchronously when the rotating rod 24 rotates, thereby moving the oil shale blocks inside the transmission pipe 21. The spiral plate 25 is more stable when rotating inside the transmission pipe 21, and at the same time, it can prevent the oil shale blocks from leaking from the gap between the spiral plate 25 and the transmission pipe 21 when the spiral plate 25 rotates.

[0025] The motor 22 in this application is a common electromechanical device in industrial equipment, and it is a product that can be directly purchased on the market. Its principle, connection method and control method are all existing technologies known to those skilled in the art, so they will not be described in detail here.

[0026] The rotating rod 24 and the spiral plate 25 in this application, as well as all movable parts, require regular cleaning and maintenance, including but not limited to dust removal and lubrication.

[0027] Example 2, as Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0028] The connecting structure 3 includes a connecting plate 31, adjusting holes 32, bolts 33 and nuts 34. The connecting plate 31 is fixedly connected to the outer surface of the lower end of one end of the transmission pipe 21. Multiple sets of adjusting holes 32 are provided, and the multiple sets of adjusting holes 32 are respectively opened inside the outer surface of the connecting plate 31. Bolts 33 are engaged inside the multiple sets of adjusting holes 32. Nuts 34 are threadedly connected to the outer surface of the lower end of the bolts 33. The multiple sets of adjusting holes 32 are evenly distributed inside the outer surface of the connecting plate 31. The external dimensions of the bolts 33 are adapted to the internal dimensions of the adjusting holes 32.

[0029] In this embodiment, the bolt 33 can move inside the adjustment hole 32, and the bolt 33 can move more stably. By adjusting the position of the bolt 33, it can be adjusted to match the external equipment that needs to be connected, thereby facilitating the connection of the equipment with external equipment of different specifications.

[0030] Working principle: When using the equipment, first, attach the connecting plate 31 to the position where the feed inlet of the distillation furnace needs to be connected. Then, move the bolt 33 to a suitable position inside the adjusting hole 32 and thread the bolt 33 into the feed inlet of the equipment. Rotate the nut 34 so that its thread is on the outer surface of the bolt 33 and tighten it. This connects the equipment. Then, start the motor 22 to drive the rotating rod 24 to rotate, and make the spiral plate 25 rotate synchronously inside the transmission pipe 21. This will drive the oil shale blocks that have entered the transmission pipe 21 through the connecting pipe 1 to move outward. At the same time, the speed of the rotating rod 24 can be controlled by controlling the motor 22, thereby controlling the transmission speed of the oil shale blocks. This is the complete working principle of this utility model.

[0031] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.

[0032] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0033] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model.
