This embodiment drives broken grinding kettle 200 through drive arrangement, and then makes broken grinding kettle 200 drive and hold grinding dish 205 and rotate, and the building crushed aggregates that gets into first grinding chamber 114 like this is carried out the second grade by primary grinding, and the building crushed aggregates by primary grinding reentrants second grinding chamber 115 is gone on and is ground, makes grit and lime fully separate like this. In this embodiment, in order to improve the polishing effect and avoid the problem of sputtering of sand, etc., a plurality of annular polishing grooves 110 having a triangular radial cross section are formed on the lower end surface of the second polishing disk 111.
As a preferred embodiment of the present invention, in order to make the building crushed aggregates more sufficiently ground and crushed in the first grinding chamber 114 and dissolve the ground lime in water to avoid lime flying, as shown in fig. 3, 5, 7 and 9-10, a plurality of grinding heads 109 extending into the first grinding chamber 114 are uniformly installed on the first grinding disc 106, the grinding head 109 has a connecting seat 1091, the connecting seat 1091 is detachably connected to the first grinding disc 106, a grinding head body 1092 is configured on the lower end surface of the connecting seat 1091, a water through hole 1093 is opened on the grinding head body 1092, the lower end of the grinding head body 1092 is a cone-shaped or round-head-shaped fracturing grinding head 1094, different types of grinding head bodies 1092 are selected according to different building materials and crushed aggregate volumes, and in general, when the crushed aggregate volume is small, the type of the grinding head body 1092 is a round-head 1094 having a round-head-shaped structure at the lower end, thus greatly improving the grinding sufficiency; when the crushed aggregates are large in size, the grinding head body 1092 with the conical end is selected, so that the fracturing grinding head 1094 with the conical structure can be conveniently inserted into the crushed aggregates for subsequent fracturing. The concrete fracturing mode is that the high-pressure water beam is jetted from the lower end of the grinding head body 1092 and shatters the crushed aggregates of the building, a jet hole 1095 communicated with a water through hole 1093 is formed in the grinding head body 1092, and the jet hole 1095 penetrates through the end of the lower end of the grinding head body 1092 in the vertical direction. In this embodiment, a plurality of annular water distribution holes 108 with different sizes and coinciding axes are formed in the first grinding disk 106, the annular water distribution holes 108 are communicated with each other through a plurality of water distribution channels 107, and the water supply main 100 is communicated with the first grinding chamber 114 through the high pressure channel 105 of the mounting rod 102, the water distribution channels 107 in the first grinding disk 106 and the jet channels of the grinding head 109. High-pressure water enters the grinding head 109 from the high-pressure channel 105 through the first grinding disc 106, the grinding head 109 jets out high-pressure water, and the building crushed aggregates are compacted by the first grinding disc 106, so that the problem that the building crushed aggregates are sputtered in the shattering process of the high-pressure water in the shattering process of the jet flow. And the shattering and grinding actions are performed simultaneously, and the grinding head 109 does not perform the shattering action and also performs the grinding action.
As a preferred embodiment of the present invention, in order to make the first grinding disc 106 perform pulse type impact fracturing on the building debris, as shown in fig. 3-4 and 7, a mounting sleeve 101 is configured at the lower end of a water main 100, a plug 103 is configured at the upper end of a mounting rod 102, the plug 103 is inserted into the mounting sleeve 101, a hydraulic adjusting spring 104 is fixedly mounted in the mounting sleeve 101, the lower end of the hydraulic adjusting spring 104 is fixedly connected with the upper end of the plug 103, high-pressure water enters the mounting sleeve 101 through the water main 100, under the instant pressure increase, the mounting rod 102 impacts downwards, so that the mounting rod drives the first grinding disc 106 to impact the building debris, and due to the increase of the water pressure, the pressure of water beams jetted by the grinding head 109 is instantly increased, so as to improve the fracturing efficiency, and after the water pressure is reduced, the hydraulic adjusting spring 104 is reset, thereby causing the mounting rod 102 to return the first abrasive disk 106. The present embodiment may also control the water pressure according to the specific situation of the building debris being ground, so that the gap of the first grinding chamber 114 is adaptively adjusted. In order to facilitate the construction waste to smoothly enter the first grinding chamber 114, the present embodiment is configured with a gathering rim 202 at the upper end of the crushing and grinding tank 200.
As a preferred embodiment of the present invention, in order to make it possible to control the sizes of the first grinding chamber 114 and the second grinding chamber 115 by means of water pressure, i.e. to adjust the first grinding chamber 114 and the second grinding chamber 115 to be simultaneously increased or decreased to be adapted to the corresponding building debris, measures are taken that, as shown in fig. 13, the first grinding disk 106 and the second grinding disk 111 are slidably connected, a hard spring 209 is arranged between the first grinding disk 106 and the second grinding disk 111, the hard spring 209 connects the two, a water supply manifold 100 is communicated with the connection between the first grinding disk 106 and the second grinding disk 111 through a mounting rod 102, the mounting rod 102 arranged here can move up and down, unlike the above, and the hydraulic adjustment spring 104 is not connected, and the mounting rod 102 is normally driven by a hydraulic cylinder to move up and down. Through hydraulic pressurization or decompression, water pressure presses the second grinding disc 111, the second grinding disc 111 moves up or down under the action of the water pressure and the elastic force of the hard spring 209, and meanwhile, the first grinding disc 106 correspondingly moves down or up under the action of the hydraulic cylinder, so that the purpose of simultaneously adjusting the sizes of the first grinding cavity 114 and the second grinding cavity 115 is achieved.
As a preferred embodiment of the present invention, in order to make the grinding of the construction waste material in a progressive form, and further make the grinding continuous, i.e. to achieve continuous feeding grinding and continuous discharging, as shown in fig. 13, the aperture sizes of the first grinding chamber 114 and the second grinding chamber 115 decrease progressively along the conveying direction of the material, such an arrangement does not achieve the above purpose, and the grinding particles are from coarse to fine, so that the grinding is more sufficient.
As a preferred embodiment of the present invention, in order to enable the ground crushed aggregates to be directly discharged to the second grinding chamber 115 through the grinding disc 205, as shown in fig. 5, a plurality of discharging holes 2051 are uniformly formed in the grinding disc 205, and the ground crushed aggregates are discharged through the discharging holes 2051, and in this embodiment, in order to avoid the problem of blockage of the discharging holes 2051, the size of the caliber of the discharging holes 2051 is gradually enlarged vertically downward, and at the same time, the discharging holes 2051 are ensured to be smooth under the action of high-pressure water. The high-pressure water also has sand and lime which are washed and ground, so that the subsequent collection of the sand and the lime and the separation of the sand and the lime are convenient.
