For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] A leakage-proof spiral sheet according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0035] The main body 100 extends up and down in a spiral shape, and includes an inner wall 110, a spiral groove 120 and an outer wall 130 which are arranged in sequence from the inside to the outside along the radial direction, so that the spiral groove 120 can support the minerals and mud to flow down, and the inner wall 110 and the outer wall 130 can limit the minerals and mud on the spiral groove 120 to prevent the minerals and mud from being thrown out of the main body 100 during the downward flow.
[0036] Reference Figure 5 Furthermore, the top end of the main body 100 along the spiral extension direction has a first splicing portion 140, and the bottom end of the main body 100 along the spiral extension direction has a second splicing portion 150. The first splicing portion 140 of one of the two adjacent main bodies 100 is overlapped and spliced with the second splicing portion 150 of the other, so that the spiral chute of the mineral processing equipment can be spliced by multiple main bodies 100, thereby reducing the processing difficulty of the spiral chute.
[0037] Specifically, a first bolt and a first threaded hole 160 are provided between the first splicing part 140 and the second splicing part 150. The first bolt and the first threaded hole 160 cooperate to press the first splicing part 140 and the second splicing part 150 that overlap each other up and down, thereby facilitating the fixing of the two adjacent main bodies 100 and making the two adjacent main bodies 100 more stable.
[0038] In some specific embodiments, the first splicing portion 140 has a first inclined surface 170, one side of which is connected to the groove surface of the spiral groove 120, and the second splicing portion 150 has a second inclined surface 180, and the first inclined surface 170 and the second inclined surface 180 are fitted together to seal the gap between the first splicing portion 140 and the second splicing portion 150 that are spliced together.
[0039] It can be understood that one side of the first bevel 170 is connected to the groove surface of the spiral groove 120, so that one side of the first bevel 170 is flush with the groove surface of the spiral groove 120, and the splicing gap between the groove surfaces of the spiral grooves 120 of the two adjacent main bodies 100 is the fitting surface of the first bevel 170 and the second bevel 180. When the first bolt and the first threaded hole 160 cooperate to press the first splicing portion 140 and the second splicing portion 150 that overlap each other up and down, the first bevel 170 and the second bevel 180 fit together up and down, and the first bevel 170 and the second bevel 180 receive pressure in the up and down directions approaching each other, so that the gap between the first bevel 170 and the second bevel 180 is smaller, thereby improving the sealing of the splicing of the two adjacent spiral sheets.
[0040] In some specific embodiments, the first splicing portion 140 has a lap step 190, which is used to support the second splicing portion 150. The upper edge of the first inclined surface 170 along the inclined direction is connected to the groove surface of the spiral groove 120, and the lower edge of the first inclined surface 170 along the inclined direction is connected to the lap step 190, so that the horizontal height of the lap step 190 is lower than the edge of the spiral groove 120 connected to the first inclined surface 170, and further, the top of the lap step 190 has a space to accommodate the second splicing portion 150 and support the second splicing portion 150, so that the splicing of the first splicing portion 140 and the second splicing portion 150 is smoother.
[0041] Furthermore, a limiting groove 200 is provided on the overlapping step 190, and a limiting convex strip 210 is provided at the bottom of the second splicing part 150. The limiting groove 200 and the limiting strip cooperate to limit the mutually spliced first splicing part 140 and the second splicing part 150 along the spiral extension direction of the main body 100, thereby making the splicing positioning of the first splicing part 140 and the second splicing part 150 more accurate and avoiding the mutually spliced first splicing part 140 and the second splicing part 150 from shaking each other.
[0042] In some specific embodiments, the limiting convex strip 210 is provided with a bulge 220, the first threaded hole 160 is provided at the bottom of the bulge 220, and the overlapping step 190 is correspondingly provided with a sinker 230, the sinker 230 accommodates the bulge 220, and the bottom wall of the sinker 230 is provided with an installation hole 240 that passes through from top to bottom, and the installation hole 240 is used to install the first bolt.
[0043] It can be understood that after the bulge 220 is installed into the sink 230 from above the mounting hole 240, the first bolt can pass through the mounting hole 240 from the bottom of the sink 230 and be threadedly connected with the first threaded hole 160 at the bottom of the bulge 220, thereby preventing the first bolt from interfering with the groove surface of the spiral groove 120 above the sink 230.
[0044] In some specific embodiments, a first slot 250 is provided at the radially inner end of the overlapping step 190 of the main body 100, and a first block 260 is provided at the second splicing portion 150. The first slot 250 and the first block 260 cooperate to limit the radial position of the first splicing portion 140 and the second splicing portion 150 spliced together along the main body 100, thereby making the mating position of the first splicing portion 140 and the second splicing portion 150 spliced together more accurate and less likely to shake.
[0045] In some specific embodiments, the overlapping step 190 extends from the radially outer end of the main body 100 to the top of the outer wall 130, and the first bevel 170 and the second bevel 180 extend to the top of the outer wall 130 accordingly, so that the fitting position of the first bevel 170 and the second bevel 180 of the two main bodies 100 spliced together can extend to the top of the outer wall 130, thereby further increasing the sealing range of the first bevel 170 and the second bevel 180 on the splicing position of the two main bodies 100.
[0046] In some specific embodiments, a second slot 270 is provided at one end of the overlapping step 190 extending to the top of the outer wall 130, and a second block 280 is provided at the second splicing portion 150. The second slot 270 and the second block 280 cooperate to limit the radial position of the first splicing portion 140 and the second splicing portion 150 that are spliced together along the main body 100.
[0047] It can be understood that when the second splicing part 150 is installed into the overlapping step 190 from above the first splicing part 140, the second clamping block 280 can be inserted into the second clamping groove 270, so that the second clamping groove 270 and the second clamping block 280 cooperate to limit the position, thereby making the first splicing part 140 and the second splicing part 150 spliced together more secure.
[0048] Furthermore, the second slot 270 has a first notch along the radial inner side of the body 100, the first notch is used to avoid the second block 280, the cross section of the second slot 270 is a trapezoidal shape that is narrow inside and wide outside, and the cross section of the second block 280 is a trapezoidal shape that is narrow inside and wide outside.
[0049] It can be understood that the outer wall 130 extends vertically upward on the spiral groove 120, and the cross section of the second slot 270 and the second block 280 is a cross section along the horizontal direction. Since the second block 280 is arranged on the second joint portion 150, and in order to cooperate with the second slot 270 located at the top of the outer wall 130, the second block 280 is correspondingly arranged at the top of the outer wall 130, and the inner side of the second block 280 is connected to the outer wall 130, by the second slot 270 along the body 100 There is a first notch on the radial inner side, so that the first notch can avoid the second block 280. Specifically, the first notch can avoid the connection between the second block 280 and the outer wall 130. At the same time, the cross-section of the second slot 270 is a trapezoid that is narrow inside and wide outside. The cross-section of the second block 280 is correspondingly a trapezoid that is narrow inside and wide outside, so that the second block 280 and the second slot 270 can cooperate to limit each other along the radial direction of the main body 100, thereby preventing the second block 280 from detaching from the second slot 270 from the first notch.
[0050] In some specific embodiments, the groove surface of the spiral groove 120 is also provided with a guide ridge 290 extending in an arc shape from the outside to the inside, so that the guide ridge 290 can guide the mineral to the inside of the spiral groove 120, so that the mineral can be closer to the inside of the spiral groove 120 during the downward flow process, thereby improving the separation effect of the main body 100 on minerals and mud.
[0051] Furthermore, a plurality of guide ridges 290 are provided, and the plurality of guide ridges 290 are sequentially arranged along the spiral extension direction of the main body 100 , thereby further improving the separation effect of the main body 100 on minerals and mud.
