[0023] In order to make the above object, features and advantages of the utility model more apparent, easy to understand, the specific embodiment of the utility model is explained in detail in the following with the drawings of the specification.

[0024] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description herein, and those skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the utility model. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment excluding other embodiments.

[0026] Embodiment 1, refer to Figures 1-3 , it is the first embodiment of the utility model, and the embodiment provides a guide mechanism, the communication assembly 100 includes the buffer tank 101 and the absorption tank 102, and the buffer tank 101 and the absorption tank 102 are provided with the upper slag pipe 103 for communication, the absorption tank 102 is provided with the slag suction pipe 104 away from the upper slag pipe 103, and the slag suction pipe 104 is communicated with the inner cavity of the absorption tank 102.When removing water slag in the sedimentation tank, the slag suction pipe 104 can be first inserted into the sedimentation tank, and the passage between the buffer tank 101 and the absorption tank 102 and the sedimentation tank is formed, which is convenient for guiding water slag in the sedimentation tank out in the later period. The guide assembly 200 includes the air pipe 201 arranged on the absorption tank 102 close to the upper slag pipe 103 position, and the inner cavity of the air pipe 201 is communicated with the inner cavity of the absorption tank 102. The air pipe 201 is arranged, which is convenient for the staff to input gas into the absorption tank 102

[0027] Further, the guide assembly 200 further comprises a valve 203 arranged on the air pipe 201, and the buffer tank 101 is provided with a slag outlet pipe 202 communicated with the inner cavity of the buffer tank 101. Since one end of the slag suction pipe 104 extends into the sedimentation tank, a water seal is formed at the slag suction pipe 104, and the air flow entering the suction tank 102 through the air pipe 201 will enter the buffer tank 101 through the upper slag pipe 103, and finally flow out from the slag outlet pipe 202 communicated with the buffer tank 101. According to Bernoulli's principle, the greater the flow rate, the smaller the pressure. Therefore, in the uninterrupted flow of the air flow, a negative pressure will gradually appear in the suction tank 102, causing the siphon phenomenon, so that the water and slag mixture in the sedimentation tank will first enter the suction tank 102 through the slag suction pipe 104, then enter the buffer tank 101 through the upper slag pipe 103, and finally flow into the spiral classifier through the slag outlet pipe 202 communicated with the buffer tank 101 to realize the separation of water and slag. Thus, under the action of the pressure difference, the water and slag in the sedimentation tank are transported out until the water level in the sedimentation tank is lower than the inlet of the slag suction pipe 104. This method not only can extract water and slag at any time, but also can save resources. In addition, after the siphon phenomenon is formed, the valve 203 can be closed to prevent water and slag from entering the air pipe 201

[0028] The valve 203 comprises a valve core 203a rotatably arranged in the inner cavity of the air pipe 201, a valve rod 203b coaxially fixed at the axis of the valve core 203a, and a knob 203c arranged at one end of the valve rod 203b. In the normal state, the valve core 203a is parallel to the air pipe 201, at this time the air pipe 201 is in the open state, and when closed, the valve core 203a can be closed by rotating the knob 203c in cooperation with the valve rod 203b.

[0029] In use, air flow is blown out through the air pipe 201 to cause a negative pressure in the suction tank 102, causing the siphon phenomenon, so that the water and slag mixture in the sedimentation tank will flow into the spiral classifier through the components such as the slag suction pipe 104, the upper slag pipe 103 and the slag outlet pipe 202 to realize the separation of water and slag. Thus, under the action of the pressure difference, the water and slag in the sedimentation tank are transported out until the water level in the sedimentation tank is lower than the inlet of the slag suction pipe 104. This method not only can extract water and slag at any time, but also can save resources.

[0030] Embodiment 2, refer to Figures 1-3 The second embodiment of the utility model is different from the previous embodiment in that it further comprises a slag suction pipe 104, an air pipe 201 and a slag outlet pipe 202, and one end of each of the slag suction pipe 104, the air pipe 201 and the slag outlet pipe 202 is provided with a connecting flange 105. The connecting flange 105 is arranged to facilitate the connection of the slag suction pipe 104, the air pipe 201 and the slag outlet pipe 202 with external equipment, thereby improving the convenience of communication between the components.

[0031] Further, the slag outlet pipe 202 is inclinedly arranged, and the highest end of the slag outlet pipe 202 is communicated with the buffer tank 101. Since the highest end of the slag outlet pipe 202 is communicated with the buffer tank 101, the water slag entering the buffer tank 101 will flow out of the buffer tank 101 quickly under the action of gravity and air pressure, thereby improving the efficiency of cleaning the water slag.

[0032] Further, the slag outlet pipe 202 is inclinedly arranged, and the highest end of the slag outlet pipe 202 is communicated with the buffer tank 101. Since the highest end of the slag outlet pipe 202 is communicated with the buffer tank 101, the water slag entering the buffer tank 101 will flow out of the buffer tank 101 quickly under the action of gravity and air pressure, thereby improving the efficiency of cleaning the water slag.

[0033] Further, the cross section of the buffer tank 102 is conical, and the internal size of the buffer tank 102 decreases in sequence from top to bottom. Since the cross section of the buffer tank 102 is conical and the internal size of the buffer tank 102 decreases in sequence from top to bottom, such design is helpful to maintain the continuity of liquid flow in the siphon system, because the flow of liquid is more concentrated at the bottom of the conical shape, which is helpful to form stable siphon flow. Moreover, the conical design can reduce the formation of bubbles when the liquid flows, which is very important for maintaining the efficiency of the siphon system and avoiding air entering the system.

[0034] In use, the water slag in the buffer tank 101 will not flow back to the sedimentation tank along the slag outlet pipe 103 when the slag removal operation is stopped, thereby improving the slag removal quality of the device, and in addition, the conical design of the buffer tank 102 is helpful to maintain the continuity of liquid flow and improve the stability of siphon flow.

[0035] Embodiment 3, refer to Figure 4 As a third embodiment of the present application, the embodiment further provides a water slag extraction device. The device comprises a mounting assembly 300, which comprises a mounting plate 301 fixedly mounted on the buffer tank 101, and a plurality of mounting holes 302 for mounting the buffer tank 101 are arranged on the mounting plate 301. The mounting plate 301 and the mounting holes 302 arranged thereon facilitate the mounting of the buffer tank 101 near the sedimentation tank by the mounting bolts.

[0036] Further, the edges of the mounting plate 301 are all provided with smooth curved surfaces. The design of the smooth curved surfaces facilitates the transfer of the buffer tank 101 and reduces the risk of injury to the transfer personnel at the edges of the mounting plate 301.

[0037] In use, through the design of the mounting plate 301 and the mounting holes 302 thereon, it is convenient for workers to install the buffer tank 101 near the sedimentation tank through the mounting portion bolts, and in addition, through the curved surface design at the edge of the mounting plate 301, the risk that the edge of the mounting plate 301 may generate during equipment transfer is reduced.
