Description

Technical Field

[0001] This utility model relates to the field of kiln-type roasting furnace technology, specifically a rotary kiln-type roasting furnace for drilling water-based slag rock. Background Technology

[0002] Drilling water-based slag is a type of waste generated during oil and gas drilling. It typically contains a certain amount of water, which is evaporated and removed after roasting, resulting in a significant reduction in its volume. This not only effectively reduces the space occupied by the waste, facilitating subsequent transportation and storage, but also lowers the costs and resources required to process large quantities of drilling waste.

[0003] The rotary kiln roasting furnace for drilling water-based slag is a thermal device specifically designed for processing water-based slag generated during drilling. In operation, the user pours the drilling water-based slag into the rotating drum of the furnace, and then controls its rotation while simultaneously heating the surface of the drum through burners to achieve roasting. However, drilling water-based slag is generally in powder or granular form, and the opening of the rotating drum in the rotary kiln roasting furnace is typically large. Therefore, during discharge, powdery drilling water-based slag may splash out from the opening of the rotating drum, resulting in a high particulate matter content in the environment and affecting the health of workers. Therefore, a new type of rotary kiln roasting furnace for drilling water-based slag is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when the rotary kiln roasting furnace for drilling water-based slag rocks discharges material, powdery drilling water-based slag rocks may splash out from the opening end of the rotary drum of the furnace, resulting in a large amount of particulate matter in the environment and affecting the health of the workers. This utility model provides a kiln roasting furnace.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A rotary kiln roasting furnace for drilling water-based slag rocks includes: a mounting frame, on the inner wall of which a drum is rotatably mounted; a heating unit and a driving unit, wherein the heating unit is used to heat the surface of the drum, and the driving unit is used to drive the drum to rotate.

[0007] One end of the mounting bracket is rotatably mounted with a baffle, and it also includes a gap control unit, which is used to intermittently rotate a portion of the baffle.

[0008] Furthermore, the roller includes a cylinder body, and the inner walls at both ends of the cylinder body are respectively provided with a first inclined surface and a second inclined surface.

[0009] Furthermore, the inner wall of the mounting bracket is rotatably connected to several rotating rods, and the surfaces of the several rotating rods are fixedly fitted with two rollers. The surface of the cylinder is provided with two sliding grooves, and the surfaces of the several rollers are respectively slidably inserted into the inner walls of the two sliding grooves.

[0010] Furthermore, the heating unit includes several burners that are fixedly installed on the inner wall of the mounting frame, and a controller is fixedly installed on the surface of the mounting frame. The controller is electrically connected to the several burners.

[0011] Furthermore, the drive unit includes a small gear fixedly mounted on one end of one of the rotating rods, a large gear meshing with the surface of the small gear, the large gear being rotatably mounted on the surface of the mounting bracket, a drive motor being fixedly mounted on the surface of the mounting bracket, and the output end of the drive motor being fixedly mounted on the surface of the large gear and electrically connected to the controller.

[0012] Furthermore, the gap control unit includes a protrusion disposed on the surface of the cylinder, a wear-resistant sleeve is fixedly sleeved on the surface of the baffle, and a third inclined surface is disposed on the surface of the protrusion.

[0013] Furthermore, the inner wall of the cylinder is provided with a spiral edge.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, a roller is rotatably installed on the inner wall of the mounting frame. During use, the user needs to pour drilling water-based cuttings into the inside of the roller. Then, the roller is heated by the heating unit and driven to rotate by the drive unit, which can achieve the roasting of the drilling water-based cuttings inside the roller. At the same time, under the action of the gap control unit, the baffle will open intermittently, so that the drilling water-based cuttings inside the roller will be discharged intermittently from one end of the roller. This achieves the intermittent discharge of drilling water-based cuttings and avoids the situation of dust splashing due to the roller opening being too large (this situation will not affect the discharge speed, because even without the roller, the drilling water-based cuttings will also be discharged from the lower part of the roller).

[0016] 2. In this utility model, a protrusion is provided on the surface of the cylinder, and a third inclined surface is provided on the surface of the protrusion. Therefore, during the rotation of the cylinder, the third inclined surface will abut against the surface of the wear-resistant sleeve, thereby driving the baffle to swing, and the baffle is opened intermittently by rotating the cylinder.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This embodiment provides a rotary kiln roasting furnace for drilling water-based lithology, mainly used to solve the problem that during the discharge of the rotary kiln roasting furnace for drilling water-based lithology, powdery drilling water-based lithology may splash out from the opening end of the rotary drum, resulting in a high content of particulate matter in the environment and affecting the health of workers. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0024] A rotary kiln-type calcining furnace for drilling water-based cuttings includes: a mounting frame 1 with a roller 2 rotatably mounted on its inner wall. During use, the user drives the roller 2 to rotate via a drive unit 4, while a heating unit 3 heats the surface of the roller 2, thus achieving uniform heating of the drilling water-based cuttings. Because a baffle 5 is rotatably mounted at one end of the mounting frame 1, a gap control unit 6 can intermittently rotate the baffle 5 at a certain angle during use, allowing the drilling water-based cuttings to be intermittently discharged from the gap between the roller 2 and the baffle 5. The main component of the roller 2 is a cylinder 21 with a first inclined surface 22 and a second inclined surface 23 respectively opened at both ends of its inner wall. During use, the user pours the drilling water-based cuttings from the surface of the first inclined surface 22. The drilling water-based cuttings are fed into the cylinder 21 and then discharged from the second inclined plane 23 after being heated and roasted. (The first inclined plane 22 and the second inclined plane 23 have different inclination directions, which can accelerate the feeding and discharging respectively.) The main components of the heating unit 3 are: several burners 31, all of which are fixedly installed on the inner wall of the mounting frame 1. In use, the user needs to control the several burners 31 to heat the surface of the cylinder 21 through the controller 32 fixedly installed on the surface of the mounting frame 1, thereby realizing the roasting of the drilling water-based cuttings inside the cylinder 21. The cylinder 21 is rotatably installed on the inner wall of the mounting frame 1 by: several rotating rods 7, all of which are rotatably inserted into the inner wall of the mounting frame 1. At the same time, two sliding grooves 9 are opened on the surface of the drum 2, and several rods are fixedly sleeved on the two... Rollers 8 on the surface of rotating rod 7 are slidably inserted into the inner walls of two sliding grooves 9. Therefore, when the user drives one of the rotating rods 7 to rotate via the drive unit 4, the cylinder 21 will rotate synchronously. The main components of the drive unit 4 are: a large gear 42 that is rotated and mounted on the surface of the mounting bracket 1, and a small gear 41 meshing with the surface of the large gear 42. In use, the user can control the output end of the drive motor 43 fixedly mounted on the surface of the mounting bracket 1 to rotate via the controller 32, thereby driving the large gear 42 fixedly mounted on the output end of the drive motor 43 to rotate, further driving the small gear 41, and driving the rotating rod 7 fixedly mounted on one end of the small gear 41, thus driving the cylinder 21. The gap controller 32 is used for this purpose. The main components of the unit are: a wear-resistant sleeve 62 fixedly fitted onto the surface of the baffle 5 (the interior of the wear-resistant sleeve 62 is made of a relatively hard material, while the surface is made of rubber, and it can be fixed to the surface of the baffle 5 by welding). During use, the cylinder 21 rotates, and the protrusion 61 on its surface first abuts against the surface of the baffle 5, and the third inclined surface 63 on the surface of the protrusion 61 first contacts the baffle 5, thereby lifting the baffle 5 and creating a partial gap between the cylinder 21 and the baffle 5, which achieves the purpose of material discharge (this method of material discharge can avoid dust flying due to the excessively large opening of the cylinder 21, and can also achieve intermittent material discharge for drilling water-based briquette). It should be noted that the burner 31 is a key component of the rotary kiln roasting furnace for drilling water-based briquette.Its main function is to provide heat to the rotary kiln roasting furnace, ensuring the kiln temperature reaches the required conditions for roasting water-based clastic rocks. During the roasting process of drilling water-based clastic rocks, sufficient heat is needed to drive physicochemical reactions such as moisture evaporation, organic matter decomposition, and phase transitions of mineral components. Burner 31 heats the material by generating high-temperature flames and hot gas through fuel combustion; this is a relatively mature existing technology, similar to natural gas burners, oil burners, and liquefied petroleum gas burners.

[0025] A roller 2 is installed by rotating it on the inner wall of the mounting frame 1. During use, the user needs to pour drilling water-based cuttings into the inside of the roller 2. Then, the heating unit 3 heats the roller 2 while the drive unit 4 drives the roller 2 to rotate, thus roasting the drilling water-based cuttings inside the roller 2. At the same time, under the action of the gap control unit 6, the baffle 5 will open intermittently, so that the drilling water-based cuttings inside the roller 2 will be discharged intermittently from one end of the roller 2. This achieves intermittent discharge of drilling water-based cuttings and avoids dust splashing due to the excessively large opening of the roller 2 (this situation will not affect the discharge speed, because even without the roller 2, the drilling water-based cuttings will still be discharged from the lower part of the roller 2).

[0026] By setting a protrusion 61 on the surface of the cylinder 21, and opening a third inclined surface 63 on the surface of the protrusion 61, the third inclined surface 63 will abut against the surface of the wear-resistant sleeve 62 during the rotation of the cylinder 21, thereby driving the baffle 5 to swing, and the baffle 5 will be opened intermittently by rotating the cylinder 21.

[0027] like Figure 2 As shown, in some embodiments, a spiral edge 10 is provided on the inner wall of the cylinder 21, so that the drilling water-based cuttings inside the cylinder 21 will be driven forward by the spiral edge 10 inside the cylinder 21, and finally discharged in an accumulated state when it moves to the second inclined surface 23.

[0028] The working process of this utility model is as follows:

[0029] First, the user needs to pour the drilling water-based cuttings into one end of the cylinder 21. Then, the controller 32 controls the output of the drive motor 43 to rotate, which drives one of the rotating rods 7 to rotate, thereby driving the cylinder 21. The controller 32 controls the burner 31 to heat the drilling water-based cuttings inside the cylinder 21, thus achieving the roasting of the drilling water-based cuttings.

[0030] Secondly, during the roasting process, the spiral edge 10 of the inner wall of the inclined cylinder 21 will drive the drilling water-based cuttings to move inside the cylinder 21, thereby realizing the conveying of the drilling water-based cuttings in the cylinder 21. Finally, after moving to the second inclined surface 23, the rotating cylinder 21 will drive the third inclined surface 63 of the protrusion 61 to abut against the surface of the wear-resistant sleeve 62, thereby realizing the intermittent lifting of the baffle 5, that is, the discharge of the drilling water-based cuttings.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
