Description

Technical Field

[0001] The utility model relates to the technical field of feeding sieves, and specifically relates to a feeding sieve for sludge stirring. Background Art

[0002] When dealing with sludge, stirring is an important step because it involves a technology called in-situ solidification of soft soil, which is achieved by spraying a curing agent during the stirring process. The components of the curing agent include cement, lime, etc. When these materials are mixed with sludge, a series of physical and chemical reactions will occur, causing the water molecules in the soil to be fixed in the form of crystal water, thereby achieving the purpose of solidification.

[0003] Before the sludge is stirred and processed, it is necessary to screen the sediment in the sludge. At this time, a feeding sieve is required. Since the sediment content in the sludge in different regions or river channels is different, and the diameter of the sediment is different, and the larger the mesh size of the feeding sieve, the faster the sludge passes through. However, if the mesh size is too large, it cannot achieve the function of filtering sediment. In the existing technology, when screening sludge, the diameter of the holes in the feeding sieve is fixed. Therefore, when the diameter of the sediment in the sludge is large and the mesh diameter of the feeding sieve is small, the sludge cannot be filtered maximally. Content of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the existing technology and provide a feeding sieve for sludge stirring.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a feeding sieve for sludge stirring, including a fixing frame, the fixing frame is arranged on a vibrating sieve, and further includes:

[0006] An adjustable sludge sieve, which is arranged on the fixing frame and is used to adjust the aperture for sediment screening;

[0007] Wherein, the adjustable sludge sieve includes a first fixed shaft, the first fixed shaft is installed inside the fixing frame, a first movable plate and a first spring are sleeved on the outer surface of the first fixed shaft, a threaded rod is threadedly connected to the top of the fixing frame, a second movable plate is sleeved inside the fixing frame, one sides of the first movable plate and the second movable plate are both connected with a feeding sieve body, a notch is opened on one side of the second movable plate, a second fixed shaft is installed inside the notch, a second spring and a limiting member are sleeved on the outer surface of the second fixed shaft, a connecting frame is sleeved inside the fixing frame, both ends of the connecting frame pass through the fixing frame and are installed with movable frames, and a fixed locking tooth is installed on one side of the fixing frame.

[0008] As described above, the first spring elastically supports between the first movable plate and the fixing frame, and the threaded rod is in pressing contact with the first movable plate.

[0009] As described above, when the threaded rod presses against the first movable plate, the two feeding screen bodies can come into contact.

[0010] As described above, the second spring elastically supports between the notch and the limiting member.

[0011] As described above, the bottom of the limiting member is tooth-shaped, and the limiting member is movably clamped with the fixed teeth.

[0012] At the bottom end, a chamfer is provided at the low end of the movable frame, and the movable frame is in pressing contact with the limiting member.

[0013] Compared with the prior art, this feeding screen for silt stirring has the following beneficial effects:

[0014] First, through the cooperation between the connecting frame and the fixed frame, the present utility model can drive the movable frame to move left and right. Thus, the chamfer at the bottom of the movable frame can press against the limiting member, causing the limiting member to move along the outer surface of the second fixed shaft and separate from the fixed teeth. Subsequently, the movable frame will push the limiting member and drive the second movable plate to move, thereby causing the two feeding screen bodies to be misaligned, and then reducing the maximum diameter of the mesh holes between them to adapt to silt with different sediment contents.

[0015] Second, through the cooperation between the threaded rod and the fixed frame, the threaded rod can rotate along the top of the fixed frame and separate from the first movable plate. At this time, due to the elastic force of the first spring, when the threaded rod releases the extrusion of the first movable plate, it will drive the first movable plate to move along the outer surface of the first fixed shaft, thereby separating the two feeding screen bodies, avoiding the generation of friction between the two feeding screen bodies when they move, and making their movement smoother.

[0016] Other advantages, objectives and features of the present utility model will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-4 shown, the present invention provides a technical solution for a feed sieve for silt stirring: a feed sieve for silt stirring, including a fixed frame 1, the fixed frame 1 is arranged on the vibrating sieve, and further includes:

[0024] An adjustable silt sieve, which is arranged on the fixed frame 1 and is used to adjust the aperture for screening sediment;

[0025] Among them, the adjustable silt sieve includes a first fixed shaft 2, the first fixed shaft 2 is installed inside the fixed frame 1, the outer surface of the first fixed shaft 2 is sleeved with a first movable plate 3 and a first spring 4, the top of the fixed frame 1 is threadedly connected with a threaded rod 5, the inside of the fixed frame 1 is sleeved with a second movable plate 6, one side of the first movable plate 3 and the second movable plate 6 are both connected with a feed sieve body 7, a notch 8 is opened on one side of the second movable plate 6, a second fixed shaft 9 is installed inside the notch 8, the outer surface of the second fixed shaft 9 is sleeved with a second spring 10 and a limiting member 11, a connecting frame 14 is sleeved inside the fixed frame 1, both ends of the connecting frame 14 pass through the fixed frame 1 and are installed with a movable frame 13, and a fixed engaging tooth 12 is installed on one side of the fixed frame 1.

[0026] Through the elastic force of the first spring 4, when the threaded rod 5 releases the extrusion of the first movable plate 3, it will drive the first movable plate 3 to move along the outer surface of the first fixed shaft 2, so as to separate the two feed sieve bodies 7, avoid large friction between the feed sieve bodies 7, and at the same time, through the cooperation between the connecting frame 14 and the fixed frame 1, it can drive the movable frame 13 to move left and right, so that the chamfer at the bottom of the movable frame 13 can squeeze the limiting member 11, make the limiting member 11 move along the outer surface of the second fixed shaft 9 and separate from the fixed engaging teeth 12, and then the movable frame 13 will push the limiting member 11 and drive the second movable plate 6 to move, thereby causing the two feed sieve bodies 7 to be misaligned, and further reducing the maximum diameter of the mesh holes between them to make it adapt to silt with different sediment contents.

[0027] As shown Figure 2 in Figure 1, the first spring 4 is elastically supported between the first movable plate 3 and the fixed frame 1, and the threaded rod 5 is in pressing contact with the first movable plate 3.

[0028] Through the design of the first spring 4, the first movable plate 3 has good elastic reset performance. At this time, since the first spring 4 is in a compressed state, a elastic force will be exerted on the first movable plate 3, so that the two groups of feeding sieve bodies 7 can be separated by driving the first movable plate 3.

[0029] As shown Figure 2 in Figure 2, when the threaded rod 5 presses the first movable plate 3, the two groups of feeding sieve bodies 7 can come into contact.

[0030] Through the cooperation between the threaded rod 5 and the fixed frame 1, the threaded rod 5 can rotate along the top of the fixed frame 1 and press the first movable plate 3. Thus, through the cooperation between the first movable plate 3 and the first fixed shaft 2, the feeding sieve body 7 can be driven to move, so that the two groups of feeding sieve bodies 7 can come into contact, and the sludge can pass through the two groups of feeding sieve bodies 7 simultaneously.

[0031] As shown Figure 4 in Figure 3, the second spring 10 is elastically supported between the notch 8 and the limiting member 11.

[0032] Through the design of the second spring 10, the limiting member 11 has good elastic reset performance. At this time, since the second spring 10 is in a compressed state, a elastic force will be exerted on the limiting member 11, so that the cooperation between the limiting member 11 and the fixed tooth 12 is tighter.

[0033] As shown Figure 4 in Figure 4, the bottom of the limiting member 11 is tooth-shaped, and the limiting member 11 is movably clamped with the fixed tooth 12.

[0034] Through the cooperation between the limiting member 11 and the second fixed shaft 9, the limiting member 11 can move up and down along the outer surface of the second fixed shaft 9. At the same time, since the bottom of the limiting member 11 is tooth-shaped, through the cooperation between the limiting member 11 and the fixed tooth 12, the second movable plate 6 can be limited.

[0035] As shown Figure 4 in Figure 5, the bottom end of the movable frame 13 is provided with a chamfer, and the movable frame 13 is in pressing contact with the limiting member 11.

[0036] Through the chamfer provided at the bottom of the movable frame 13, when the movable frame 13 exerts pressure on the limiting member 11, an upward force will be applied to the limiting member 11, thereby driving the separation of the limiting member 11 from the fixed teeth 12. At the same time, a pushing or pulling force will be exerted on the limiting member 11 by both sides of the inner wall of the movable frame 13, facilitating the control of the left and right movement of the second movable plate 6, and further enabling the staggering of the two groups of feed sieve bodies 7 to change the size of the silt passing through.

[0037] Working principle:

[0038] First of all, the staff can rotate the threaded rod 5 to relieve the pressure on the first movable plate 3. At the same time, due to the elastic force of the first spring 4, the first movable plate 3 will be driven to move along the outer surface of the first fixed shaft 2, so as to separate the two groups of feed sieve bodies 7, avoiding large frictional forces between the feed sieve bodies 7. At the same time, through the cooperation between the connecting frame 14 and the fixed frame 1, the movable frame 13 can be driven to move left and right, so that the chamfer at the bottom of the movable frame 13 can squeeze the limiting member 11, causing the limiting member 11 to move along the outer surface of the second fixed shaft 9 and separate from the fixed teeth 12. Subsequently, the movable frame 13 will push the limiting member 11 and drive the second movable plate 6 to move, thus causing the two groups of feed sieve bodies 7 to be misaligned, and then reducing the maximum diameter of the mesh holes between them to make it suitable for silt with different sediment contents.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
