Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mine underground drainage and slag removal technology, and in particular to a double-sealed orifice slag removal device. Background Technology
[0002] Orifice slag removal devices are commonly used in underground coal mines, primarily for extracting and discharging or ejecting methane, harmful gases, dust, and outburst-prone coal during drilling to prevent blowouts. Existing orifice slag removal devices suffer from rapid wear and poor sealing at the drill rod sealing points, resulting in inadequate sealing during drilling. Therefore, improvements are necessary to further address the issues of sealing and preventing blowouts during drilling. This product is a purely mechanical structure, requiring no electricity, and features a simple structure, light weight, high practicality, and ease of use.
[0003] How to design a cleverly designed, simple, power-free, lightweight, practical, and easy-to-use double-sealed orifice slag discharge device is a technical problem that needs to be solved in the existing technology. Utility Model Content
[0004] To address the technical problems of existing orifice slag removal devices, such as rapid wear of the drill rod sealing parts, poor sealing effect, and poor sealing performance at the hole sealing position, resulting in poor hole sealing effect during drilling, this utility model provides a double-sealed orifice slag removal device. It achieves the goals of ingenious design, simple structure, no power supply required, light weight, strong practicality, and convenient use.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a double-sealed orifice slag discharge device, including a sealing mechanism, a collecting mechanism, and a sealing mechanism. The sealing mechanism includes multiple pressure plates, sealing rings, multiple support plates, a telescopic sleeve I, a sealing sleeve, and a telescopic sleeve II. The pressure plates and sealing rings are fixed to the support plates by bolts. The front and rear ends of the telescopic sleeve I and the telescopic sleeve II are both fixed by the support plates to form a front and rear double-sealed structure. A collecting mechanism is provided between the telescopic sleeve I and the telescopic sleeve II. The collecting mechanism includes a collecting pipe, a fixing ring, a handle, a slag discharge pipe, and a connecting plate. The fixing ring and the handle are welded to the surface of the collecting pipe. The slag discharge pipe is located at the lower end of the collecting pipe. The connecting plate is located at the front and rear ends of the collecting pipe and is connected to the adjacent support plates by bolts.
[0006] As a further optimization of the above-mentioned double-sealed orifice slag discharge device, the slag discharge pipe is connected to the slag-water separation device via a flexible hose, and the slag discharge pipe and the collection pipe are connected at an inclined angle.
[0007] As a further optimization of the above-mentioned double-sealed orifice slag discharge device, the sealing mechanism includes a sealing pipe and a sealing cone sleeve.
[0008] As a further optimization of the above-mentioned double-sealed orifice slag discharge device, the sealing cone sleeve is made of rubber, and the outer diameter of the sealing cone sleeve gradually increases from the inlet end outward to adapt to the borehole diameter.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] First, this utility model includes a sealing mechanism, a collecting mechanism, and a sealing mechanism. The sealing mechanism includes multiple pressure plates, a sealing ring, multiple support plates, a telescopic sleeve I, a sealing sleeve, and a telescopic sleeve II. The pressure plates and sealing rings are fixed to the support plates by bolts. The front and rear ends of the telescopic sleeve I and the telescopic sleeve II are fixed by the support plates to form a front and rear double sealing structure. The double sealing structure is adopted, and a soft connection is added in the middle. When the drill rod bounces a lot during rotation, the soft connection component can be adjusted with the bounce, which can reduce the wear of the seal and increase the service life of the seal.
[0011] Second, the slag discharge pipe and the collection pipe are connected at an inclined angle, which makes it easier to discharge slag.
[0012] Third, the sealing cone sleeve is made of rubber. The outer diameter of the sealing cone sleeve gradually increases from the inlet end outward. When drilling, the sealing cone sleeve enters the hole and its position is adjusted according to the size of the hole to keep the hole in a sealed state, which can achieve a better sealing effect. At the same time, a soft connection is added in the middle to adapt to the adjustment of the drilling tilt, making its sealing effect even better.
[0013] Fourth, this utility model can extract and discharge or ejected gas, harmful gases, dust and outburst coal during underground drilling operations in coal mines, thus achieving the effect of preventing blowouts. Attached Figure Description

The front and rear ends of the telescopic sleeves I 104 and II 106 are both fixed by the support plates 103 to form a front-to-back... A double-sealed structure is provided; a collection mechanism 2 is provided between the telescopic sleeve I 104 and the telescopic sleeve II 106. The collection mechanism 2 includes a collection pipe 201, a fixing ring 202, a handle 203, a slag discharge pipe 204, and a connecting plate 205. The fixing ring 202 and the handle 203 are welded to the surface of the collection pipe 201. The slag discharge pipe 204 is located at the lower end of the collection pipe 201. The connecting plate 205 is located at both ends of the collection pipe 201 and is connected to the adjacent support plate 103 by bolts.

[0024] The sealing cone sleeve 302 is made of rubber, and its outer diameter gradually increases from the inlet end outward to adapt to the borehole diameter.
[0025] like Figure 5 As shown, the operation process of this utility model is as follows:
[0026] 1. Install the slag removal device of this utility model on the drill bit 4, and then connect the drill bit.
[0027] 2. After drilling, insert the front sealing mechanism 3 into the drill hole to make the sealing cone sleeve 302 form a seal with the drill hole.
[0028] 3. Secure the slag discharge device at the orifice, and connect the slag discharge pipe 204 to the slag discharge pipe 5 on the slag-water separation device 7 below with a flexible hose, and install the gas extraction pipe 6.
[0029] 4. Drilling tool 4 begins drilling into coal seam 8. Gas, harmful gases, dust and outburst coal enter the slag-water separation device 7 from the slag discharge pipe 204 and are separated and discharged respectively.
[0030] In practical applications, the slag discharge pipe 204 is a 6-inch pipe and is inclined at a 60° angle to the main body of the collection pipe, which makes it easier to discharge slag. The collection pipe 201 is made of steel, which is not easy to be damaged and has a long service life.
[0031] This utility model is ingeniously designed, simple in structure, requires no power supply, is lightweight, highly practical, and easy to use.
