Description

Technical Field

[0001] The utility model relates to the technical field of shield machines, in particular to a slag processing device for shield machines. Background Art

[0002] With the continuous advancement of urbanization, the demand for underground engineering construction is also increasing. In underground tunnel construction, shield machines are widely used, which can quickly and efficiently complete the excavation of underground tunnels. However, a large amount of slag will be generated during the excavation of the shield machine. How to effectively deal with this slag has become an urgent problem to be solved. In order to solve these problems, a new shield machine slag treatment device came into being. This device is equipped with a complete slag treatment system inside the shield machine, which can classify, process and solidify the slag while the shield machine is excavating.

[0003] The Chinese patent with the announcement number CN213763051U discloses a shield machine slag cleaning device, which includes a box body, the top of which is connected to a shield machine paddle pipe, the top of the right side of the box body is fixedly connected to a first shell, and the bottom of the inner cavity of the first shell is fixedly connected to a first motor. The existing shield machine slag processing device usually does not have the function of classifying slag during use, and is usually not convenient for cleaning the inside, which may cause certain inconvenience to the user during use.

[0004] With regard to the above-mentioned related technologies, the device has some shortcomings. In actual use, small pieces of slag in the mud are filtered through a screen, and the screen is always in a static state during use. As a result, when the mud passes through the screen, the slag is easily accumulated on the mesh due to the stationary screen, thereby blocking the flow of the mud. The blockage problem will lead to a decrease in the mud pass rate and processing efficiency, and may even cause the device to stop working. Therefore, it is necessary to provide a shield machine slag processing device to solve the above technical problems. Utility Model Content

[0005] The utility model aims to provide a shield machine slag processing device to solve at least one technical problem existing in the above-mentioned background technology.

The driving end of the motor drives the cam plate to rotate, and the cam plate acts on the pressure plate, and the elastic action of the spring and the hinged relationship between the upper screen plate and the second through slot make the screen plate produce a vibration effect. Firstly, the vibration of the screen plate causes the mud to flow and stir violently thereon, thereby increasing the fluidity of the mud. The improved fluidity of the mud makes it easier to pass through the screen, and reduces the probability of the slag on the screen plate being accumulated and blocked in the mesh.

The utility model uses the first pipe, the mounting block, the second pipe, the booster pump, the water trough and the booster pump in coordination, so that water contacts the screened mud through the water trough at the bottom of the second baffle, which can dilute the mud, increase the fluidity of the mud, make the mud pass through the screen more smoothly, and improve the filtering efficiency of the mud. After the device is used, the electronic valve on the second pipe can be opened to spray water into the interior of the guide cover through the second pipe, which has a cleaning effect on the guide cover, and the water discharged through the first pipe has a certain cleaning effect on the top of the sieve plate, which improves the convenience of people's use and reduces the difficulty of cleaning the device.

The second baffle 16 is arranged to prevent the mud and slag discharged through the guide cover 17 from directly passing through the first through groove 10 and rushing out of the device.

[0031] A mounting block 12 is fixedly installed on the upper side of one side of the box body 1, and a first pipe 11 is fixedly installed and inserted on the mounting block 12. A booster pump 24 is provided on the first pipe 11, and the booster pump 24 is fixedly connected to the upper side of one side of the box body 1. A water trough 22 is provided at the bottom of the second baffle 16 to dilute the mud and improve the fluidity of the mud.

[0032] In one of the embodiments, a toroidal guide member 14 is fixedly installed at the lower part of the interior of the box body 1, and the bottom opening position of the toroidal guide member 14 corresponds to the top position of the discharge pipe 3, so that the screened mud can quickly flow into the interior of the discharge pipe 3 for discharge, thereby improving the discharge efficiency of the mud.

[0033] In one of the preferred embodiments, a second pipe 13 is fixedly installed on the outer wall of the first pipe 11, and the second pipe 13 is connected to the interior of the first pipe 11. One side of the second pipe 13 passes through the top of one side of the box body 1 and extends to the interior of the box body 1 on one side of the guide cover 17. An electronic valve is provided on the second pipe 13, which has the effect of flushing the inside of the guide cover 17.

[0034] In one embodiment, the second through slot 21 is located lower than the first through slot 10, and the screen plate 8 is installed in an inclined state so that the mud and small slag and stone blocks can flow in a specified direction.

[0035] In one of the preferred embodiments, a symmetrically distributed first baffle 9 is fixedly installed on the top of the screen plate 8 to prevent mud and small slag and stone blocks from falling from the side of the screen plate 8 during transportation on the screen plate 8.

[0036] The working principle of the utility model is as follows: the parts not involved in the device are the same as the prior art or can be implemented by the prior art. The specific structure of the sorting mechanism 18 can refer to the prior art, which can be easily implemented by those skilled in the art. When in use, the slag first falls into the interior of the sorting mechanism 18 through the shield machine discharge pipe 19, and the sorting mechanism 18 will screen the large pieces of slag, and the small pieces of slag and mud will fall into the interior of the guide cover 17 in a mixed state, and be discharged from the right opening of the guide cover 17 through the guidance of the guide cover 17, and fall directly to the right area of ​​the top of the screen plate 8 through the obstruction of the second baffle 16, and then according to the inclination of the screen plate 8, the mud and the small pieces of slag will move to the left under the action of gravity. When passing through the screen 20, the screen 20 will filter the mud and the small pieces of slag will continue to roll to the left on the screen 20, and finally the mud will be discharged into the interior of the round-shaped guide member 14 through the screen 20, and be discharged through the discharge pipe 3 through the guidance of the round-shaped guide member 14, while the small pieces of slag will continue to roll to the left on the screen 20. The slag blocks will be discharged from the left side of the screen plate 8 through the second through slot 21, completing the screening of small slag blocks and mud. In the process of screening small slag blocks and mud, the motor 5 starts working through the switch control, and the driving end of the motor 5 drives the cam plate 4 to rotate. The cam plate 4 acts on the pressure plate 7, and the elastic effect of the spring 23 and the hinged relationship between the screen plate 8 and the second through slot 21 make the screen plate 8 produce a vibration effect. First, the vibration of the screen plate 8 causes the mud to flow and stir violently thereon, thereby increasing the fluidity of the mud. The improved fluidity of the mud makes it easier to pass through the screen 20, reducing the probability of the slag blocks on the screen plate being accumulated and blocked in the mesh. In this way, the smoothness of the screen is guaranteed, and the efficiency of the device in processing slag blocks is effectively improved. Secondly, the vibration of the screen plate 8 can also make the small slag blocks more active, increase the vibration frequency and displacement of the slag blocks, and make the small slag blocks more easily discharged from the inside of the device, further avoiding the blockage of the screen.

[0037] During the classification and treatment of slag and stone, the first pipe 11 can be connected to the external pipe, water can be input into the first pipe 11, and the booster pump 24 can be controlled to start working at the same time. The booster pump 24 will pressurize the water and discharge it through the bottom end of the first pipe 11 with a certain pressure and directly fall on the top of the sieve plate 8 located on the right side of the second baffle 16. Under the guidance of the sieve plate 8, the water passes through the water trough 22 at the bottom of the second baffle 16 and contacts the screened mud, which can dilute the mud, increase the fluidity of the mud, and make the mud pass through the screen 20 more smoothly, thereby improving the filtering efficiency of the mud. After the device is used, the electronic valve on the second pipe 13 can be opened to spray water into the interior of the guide cover 17 through the second pipe 13, so as to clean the guide cover 17, and the water discharged through the first pipe 11 has a certain cleaning effect on the top of the sieve plate 8, thereby improving the convenience of people's use and reducing the difficulty of cleaning the device.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
