Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaning equipment, specifically to a combined multi-point assembly vacuum cleaning device. Background Technology

[0002] During the tunneling process in potash mines or coal mines, tunneling machines generate a large amount of dust. Dust collection equipment is usually required to reduce the dust concentration. The most efficient dust reduction method is to set the air inlet as close as possible to the tunneling face, that is, to install the dust reduction equipment on the tunneling machine. However, in areas with poor geological conditions, falling rocks can easily damage the dust suppression equipment on top of the tunneling machine. If the dust collection equipment is installed on the side of the tunneling machine, it creates a dead zone on the other side, significantly reducing dust collection efficiency. Furthermore, to ensure the stability of potash mine or coal roadways, the cross-section needs to be minimized; therefore, it is not advisable to enlarge the cross-section of potash mine or coal roadways, nor is it suitable to use larger dust collection equipment. Therefore, a dust collection device suitable for small-section potash mine or coal roadway operations is needed. Utility Model Content

[0003] The present invention aims to provide a combined multi-point assembly dust collection device, which is suitable for operations in small cross-section potash mine tunnels or coal tunnels.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a combined multi-point assembly dust collection device, including a side-mounted top suction component and a side-mounted side suction component, which are interchangeably connected to a tunneling machine; The side-mounted side-suction assembly includes a standard air duct and a circular air inlet duct connected in sequence. The circular air inlet duct is used to connect with the standard air duct. Both the standard air duct and the circular air inlet duct of the side-mounted side-suction assembly are connected to the side of the tunneling machine. The side-mounted top suction assembly includes a standard air duct, a variable cross-section transition pipe, a front-turn upper transition pipe, an upper-turn front transition pipe, and a rectangular air inlet pipe connected in sequence. The variable cross-section transition pipe is used to connect with the standard air duct. The rectangular air inlet pipe has its long side in the horizontal direction. The standard air duct, variable cross-section transition pipe, and front-turn upper transition pipe of the side-mounted top suction assembly are all connected to the side of the tunneling machine; the upper-turn front transition pipe and the rectangular air inlet pipe are both connected to the top surface of the tunneling machine.

[0005] In this solution, components with the same name share the same structural features, differing only in size, installation method, and installation location. For example, a standard ventilation duct might be installed on the side or top of the tunneling machine. Standard ventilation ducts typically contain or are connected to a fan, which is used to remove dust from the tunneling face. The beneficial effects of this plan are: 1. In open, spacious areas, side-mounted side-suction components can be used directly, with standard air ducts installed on the side of the tunneling machine. However, when entering areas with poor geological conditions, the cross-section is reduced, resulting in poor dust removal. In such cases, the standard air ducts can be kept in place, and the "circular air inlet duct" can be replaced with "variable cross-section transition duct, front-turn upper transition duct, upper-turn front transition duct, and rectangular air inlet duct" to move the air inlet from the side of the tunneling machine to the top. Since only the pipes near the air inlet are moved to the top, the probability of being hit by falling rocks from above remains relatively low. Compared to installing all air ducts on the top, durability is significantly improved.

[0006] 2. In this scheme, the cross-section of the rectangular air inlet pipe is horizontally the longer side, that is, it adopts a low and wide air inlet form, so as to reduce the overall height of the tunneling machine and the air inlet pipe as much as possible, so as to adapt to the space requirements of small cross-sections and increase the adaptability of the overall structure to various scenarios.

[0007] Furthermore, the front end of the variable cross-section transition tube is rectangular and the rear end is circular. The vertical direction of the front cross-section of the variable cross-section transition tube is the long side. The side of the variable cross-section transition tube is divided into four surfaces, each of which is an isosceles triangle. The base of the triangle coincides with the front rectangle and the apex of the triangle coincides with the rear circle. An arc transition is set between adjacent triangles.

[0008] Furthermore, both ends of the front and rear of the upper transition pipe are rectangular, the front end of the upper transition pipe is higher than the top surface of the tunneling machine and is located on the side close to the tunneling machine, and the front end cross section of the upper transition pipe is the long side in the horizontal direction; the axis of the upper transition pipe is a horizontal arc, and both ends of the upper transition pipe are rectangular; the front end of the upper transition pipe faces the tunneling face.

[0009] Furthermore, it also includes a top-mounted suction assembly, which consists of a standard air duct, a variable cross-section transition pipe, and a rectangular air inlet pipe connected in sequence. The standard air duct, the variable cross-section transition pipe, and the rectangular air inlet pipe of the top-mounted suction assembly are all located on the top of the tunneling machine.

[0010] Furthermore, a height transition pipe is provided between the variable cross-section transition pipe of the top-mounted top-suction assembly and the rectangular air inlet pipe. The front end of the height transition pipe is shorter than the rear end, and the front cross-section of the variable cross-section transition pipe of the top-mounted top-suction assembly is the long side in the horizontal direction.

[0011] Furthermore, the air inlet of the rectangular air inlet duct is tilted upwards.

[0012] This solution also has the following effects: 1. The variable cross-section transition pipe is mainly supported by four triangular structures, and sealed by arc-shaped transitions between the triangles, achieving a transition from a circular to a rectangular cross-section. The purpose is that existing standard pipes are usually circular in cross-section. To save costs, this solution only improves the pipes near the air inlet. However, to maximize the use of the space on top of the tunneling machine, the air inlet is rectangular when it is located on top of the tunneling machine. This requires a section of pipe to transition from a circular to a rectangular shape, and the variable cross-section transition pipe achieves the above-mentioned transition function.

[0013] 2. The functions of the front-turn upper transition pipe and the upper-turn front transition pipe are both to achieve the turning of the air duct. Therefore, in order to avoid reducing the wind speed at this position, the axis of these two pipe sections is set to be arc-shaped, thereby reducing the speed loss when the wind turns, and thus ensuring the adsorption efficiency.

[0014] 3. When lateral space is limited, standard air ducts must be installed on top of the tunneling machine. Therefore, this solution also includes a top-mounted suction assembly. To ensure the flexibility of the front end of the tunneling machine, a rectangular air inlet duct is still used near the air inlet to minimize its height. To enhance the flexibility of the duct assembly, the top-mounted suction assembly uses the variable cross-section transition pipe from the side-mounted suction assembly. The difference is that it is rotated 90° during installation so that the front cross-section of the variable cross-section transition pipe is the long side in the horizontal direction. Then, a height transition pipe is added to reduce the pipe height.

[0015] 4. The rectangular air inlet is tilted upwards, which not only increases the size of the air inlet but also allows it to collect more falling dust, thus improving the efficiency of dust collection. Attached Figure Description

Detailed Implementation

[0017] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: standard duct 1, circular inlet duct 2, variable cross-section transition duct 3, isosceles triangle 31, front-to-upper transition duct 4, upper-to-front transition duct 5, rectangular inlet duct 6, and height transition duct 7.

[0018] Example The implementation examples are basically as follows Figures 1-10 As shown: A combined multi-point assembly dust collection device includes a side-mounted side-suction component, a side-mounted top-suction component, and a top-mounted top-suction component. These components are interchangeably connected to a tunneling machine. In this embodiment, the pipes are connected by aligned connections and threads. The connection between the pipes and the tunneling machine involves bolted clamps to the pipes, which are then bolted to the tunneling machine. The front and rear ends of the pipes refer to the air ducts within the intersecting ductwork; the end of the air duct closer to the tunneling face is the front end, and the opposite end is the rear end.

[0019] like Figure 10 As shown, the lower right corner indicates the direction of the tunneling face. The side-mounted side-suction assembly includes a standard air duct 1 and a circular air inlet duct 2 connected in sequence. Each standard air duct 1 is bolted to a fan or connected to a fan. The standard air duct 1 is the air duct used in existing technology, and its cross-section is circular. The fan is used to suck away dust from the tunneling face. The circular air inlet duct 2 is used to connect to the standard air duct 1. Both the standard air duct 1 and the circular air inlet duct 2 of the side-mounted side-suction assembly are bolted to the side of the tunneling machine. Figure 10 The main body of the tunneling machine in the upper right corner is hidden.

[0020] like Figure 1 , Figure 2 As shown, the side-mounted top suction assembly includes a standard air duct 1, a variable cross-section transition pipe 3, a front-turn upper transition pipe 4, an upper-turn front transition pipe 5, and a rectangular air inlet pipe 6 connected in sequence. The rear end of the variable cross-section transition pipe 3 is used to connect to the standard air duct 1. The rectangular air inlet pipe 6 has its long side in the horizontal direction. The standard air duct 1, the variable cross-section transition pipe 3, and the front-turn upper transition pipe 4 of the side-mounted top suction assembly are all connected to the side of the tunneling machine; the upper-turn front transition pipe 5 and the rectangular air inlet pipe 6 are both connected to the top surface of the tunneling machine. Figure 7 As shown, the air inlet of the rectangular air inlet duct 6 is tilted upwards.

[0021] like Figure 3As shown, the front end of the variable cross-section transition tube 3 is rectangular and the rear end is circular. The vertical direction of the front cross-section of the variable cross-section transition tube 3 is the long side. The side of the variable cross-section transition tube 3 is divided into four surfaces, each of which is an isosceles triangle 31. The base of the triangle coincides with the front rectangle and is adjacent to it. The apex of the triangle coincides with the rear circle. An arc transition is set between adjacent triangles.

[0022] like Figure 4 , Figure 5 As shown, both the front and rear ends of the upper transition pipe 4 are rectangular. The front end of the upper transition pipe 4 is higher than the top surface of the tunneling machine and is located on the side closer to the tunneling machine. The front end cross-section of the upper transition pipe 4 has its longer side in the horizontal direction. Figure 6 As shown, the axis of the upper transition pipe 5 is a horizontal arc, and both the front and rear ends of the upper transition pipe 5 are rectangular; the front end of the upper transition pipe 4 faces the tunneling face.

[0023] like Figure 8 , Figure 9 As shown, the top-mounted suction assembly includes a standard air duct 1, a variable cross-section transition pipe 3, and a rectangular air inlet pipe 6 connected in sequence. All three are located on top of the tunneling machine. A height transition pipe 7 is provided between the variable cross-section transition pipe 3 and the rectangular air inlet pipe 6. The front end of the height transition pipe 7 is shorter than the rear end. The front end of the variable cross-section transition pipe 3 is horizontally longer. To accommodate the narrow space near the tunneling face, the top-mounted suction assembly omits the "upper-turn transition pipe 5." Therefore, the length of the rectangular air inlet pipe 6 of the top-mounted suction assembly needs to be increased, exceeding the length of the rectangular air inlet pipe 6 of the side-mounted suction assembly.

[0024] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
