[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0033] like Figures 1 to 5 As shown, the sludge conveying equipment disclosed in the first embodiment of the present application includes: a shell component 10 and a conveying component 20, the shell component 10 includes a shell structure 11 and a cover plate 12, the shell structure 11 includes a first groove 111 and an opening 112, the opening 112 is located at the bottom of the first groove 111, the cover plate 12 is arranged in the first groove 111, and the projection of the opening 112 in the vertical direction is located inside the projection of the cover plate 12 in the vertical direction, the conveying component 20 includes a rotating shaft structure 21 and a spiral blade 22, the spiral blade 22 is connected to the rotating shaft structure 21, and the rotating shaft structure 21 is rotatably connected to the shell structure 11.

[0034] By applying the technical solution of the first embodiment, when there is a lot of sludge on the spiral blades 22 and the inner wall of the shell structure 11, the cover plate 12 is opened, and the cleaning device is extended from the opening into the shell structure 11 to clean the inner wall of the shell structure 11 and the spiral blades 22, so as to avoid the sludge conveying equipment from being unable to operate normally due to excessive sludge. This method can completely clean the inside of the sludge conveying equipment without removing the spiral blades 22 from the shell structure 11. The technical solution of the first embodiment effectively solves the problem of difficulty in cleaning the sludge conveying equipment in the prior art during the sludge conveying process.

[0035] like Figure 1 and Figure 3 As shown, in the technical solution of the first embodiment, the shell structure 11 includes a shell 113, a fixing portion 114 and a limiting portion 115. The fixing portion 114 is connected to the shell 113, and the limiting portion 115 is rotatably connected to the fixing portion 114. The fixing portion 114 is arranged outside the first groove 111, and the fixing portion 114 has a limiting state close to the cover plate 12 and a waiting limiting state away from the cover plate 12. The limiting portion 115 limits the cover plate 12 to prevent the cover plate 12 from being separated from the shell structure 11 during the sludge conveying process. When it is necessary to clean the inside of the shell 113, the limiting portion 115 is rotated to keep it away from the cover plate 12, and the cover plate 12 is removed to clean the spiral blade 22 and the inside of the shell 113. The setting of the limiting portion 115 makes it convenient to fix and disassemble the cover plate 12, which is convenient for the staff to operate.

[0036] like Figure 1 and Figure 3 As shown, in the technical solution of the first embodiment, the limiting portion 115 includes a second groove 1151, the fixing portion 114 is arranged in the second groove 1151, and a fastener is inserted between the limiting portion 115 and the fixing portion 114. The second groove 1151 is sleeved on the outside of the fixing portion 114, and the fixing portion 114 is a cylindrical protrusion. The limiting portion 115 can be rotated by loosening the fastener so that the limiting portion 115 switches between the limiting state and the state to be limited. The limiting portion 115 is fixed by tightening the fastener to prevent the cover plate 12 from falling off.

[0037] like Figure 1 and Figure 3As shown, in the technical solution of the first embodiment, the limiter 115 also includes a third groove 1152 and an anti-slip portion 1153. The anti-slip portion 1153 is arranged in the third groove 1152, and the height of the anti-slip portion 1153 is higher than the depth of the third groove 1152. The anti-slip portion 1153 is made of rubber material, and the rubber material has good elasticity. Since the height of the anti-slip portion 1153 is higher than the depth of the third groove 1152, the cover plate 12 is pressed under the action of the anti-slip portion 1153 and the first groove 111. At this time, the anti-slip portion 1153 has a certain elastic deformation, and since the friction coefficient of the rubber material is large, the cover plate 12 is prevented from sliding in the first groove 111 and the rotation of the limiter 115 is prevented. A sealing ring is arranged on the inner side wall of the first groove 111, and the projection of the inner side wall of the sealing ring in the vertical direction is located within the projection of the outer side wall of the cover plate 12 in the vertical direction. The setting of the sealing ring seals the connection between the cover plate 12 and the housing 113, and avoids the problem of sludge overflow.

[0038] like Figure 1 and Figure 4 As shown, in the technical solution of the first embodiment, the shaft structure 21 includes an inner shaft 211, an outer shaft 212 and a connecting portion 213, the outer shaft 212 is a hollow cylinder, the inner shaft 211 is arranged inside the outer shaft 212, the connecting portion 213 is arranged between the inner shaft 211 and the outer shaft 212, the connecting portion 213 is connected to the inner shaft 211, and the connecting portion 213 is connected to the outer shaft 212. When the sludge is transported, the shaft structure 21 is subjected to a large torsional force and is prone to breakage due to the high viscosity of the sludge itself. Compared with a solid cylindrical shaft, the shaft structure 21 composed of the inner shaft 211, the outer shaft 212 and the connecting portion 213 is prone to deformation during rotation and is not easy to break.

[0039] like Figure 1 and Figure 4 As shown, in the technical solution of the first embodiment, the connection part 213 includes a plurality of connection parts 213, and the plurality of connection parts 213 are evenly distributed along the circumferential outer side of the inner shaft 211. In the first embodiment, the connection parts 213 are four in a group, and are evenly arranged along the circumferential outer side of the inner shaft 211. The angle between the axes of adjacent connection parts 213 in each group is 90°. The connection parts 213 include a plurality of groups, and the plurality of groups of connection parts 213 are arranged at intervals along the axial direction of the inner shaft. The arrangement of the plurality of connection parts 213 further improves the strength of the entire rotating shaft structure 21.

[0040] like Figure 1 and Figure 4As shown, in the technical solution of the first embodiment, the connecting portion 213 includes a first connecting segment 2131 and a second connecting segment 2132, the first connecting segment 2131 is connected to the second connecting segment 2132, the first connecting segment 2131 is connected to the inner shaft 211, the second connecting segment 2132 is connected to the outer shaft 212, and the diameter of the second connecting segment 2132 is greater than the diameter of the first connecting segment 2131. The size of the first connecting segment 2131 is set according to the diameter of the inner shaft 211, and the size of the second connecting segment 2132 is set according to the inner diameter of the outer shaft 212, which further ensures the stability of the connection between the connecting portion 213 and the inner shaft 211 and the outer shaft 212.

[0041] like Figure 1 and Figure 5 As shown, in the technical solution of the first embodiment, the sludge conveying equipment further includes a support assembly 30, and the support assembly 30 is connected to the housing assembly 10. The support assembly 30 supports the housing assembly 10, and a universal wheel is provided at the bottom of the support assembly 30 to facilitate moving the housing assembly 10 to a suitable position.

[0042] like Figure 1 and Figure 5 As shown, in the technical solution of the first embodiment, the support assembly 30 includes a sleeve 31 and an adjusting rod 32, the adjusting rod 32 is movably arranged in the sleeve 31, and the adjusting rod 32 includes a plurality of fourth grooves 321, and the plurality of fourth grooves 321 are evenly distributed on the adjusting rod 32 along the vertical direction, and a positioning column is provided between the sleeve 31 and the fourth groove 321. The support assembly 30 is connected to the sleeve 31, and the sleeve 31 is moved to change the relative position of the adjusting rod 32 and the sleeve 31, thereby changing the height of the sleeve 31 in the vertical direction, and then changing the height of the support assembly 30 in the vertical direction to meet the requirements of different working conditions. After adjusting to a suitable position, the positioning column is inserted, and the positioning column is provided on the sleeve 31 and one end of the positioning column abuts against the corresponding fourth groove 321 to fix the sleeve 31.

[0043] The difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the diameter of the connecting portion 213 increases continuously from close to the inner shaft 211 to far away from the inner shaft 211. The frustum-shaped connecting portion 213 is not easy to break when the rotating shaft structure 21 is subjected to torsion force, which further improves the strength of the rotating shaft structure 21.
