Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically to a horizontal screw discharge sedimentation centrifuge with adjustable baffles. Background Technology

[0002] The working principle of a horizontal screw discharge sedimentation centrifuge is as follows: Materials enter the rotating drum through the feed pipe and screw outlet. Under the centrifugal force generated by high-speed rotation, the materials settle and stratify. Denser solid particles deposit on the inner wall of the drum, and the screw blades, moving relative to the drum, continuously scrape off the deposited solid particles and push them out through the discharge port. The less dense liquid phase overflows from the liquid outlet. In existing technology, baffles are welded into the screw conveying channel between the blades (see...). Figure 5 By limiting the height of the conveying channel, the compression effect of the solid phase is increased, thereby reducing the moisture content of the solid phase and intercepting impurities. The required conveying channel height varies depending on the solid content of the material; too high, the compression effect is insufficient; too low, the centrifuge's throughput is reduced. Current baffles are welded and fixed to the screw conveyor, only suitable for a single material. Appropriate baffles must be selected based on multiple trials or experience with similar materials. If a baffle is unsuitable and needs replacement, it must be returned to the factory for modification. This involves disassembling the drum, removing the screw conveyor, cutting the welded baffles, and welding new, adjusted baffles. This process is time-consuming, labor-intensive, and requires extensive material analysis and experimentation to ensure the baffle size is suitable. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a horizontal screw discharge sedimentation centrifuge with adjustable baffles. The baffle height can be adjusted on the production site to adapt to the separation of materials with different solid contents. The adjustment operation is convenient and labor-saving, and the separation effect can be adjusted more accurately.

[0004] Specifically, this utility model discloses a horizontal screw discharge sedimentation centrifuge with adjustable baffles, including a rotating drum, a screw conveyor installed inside the rotating drum, and the screw conveyor being provided with screw blades; it also includes:

[0005] An adjustable baffle assembly includes a baffle and an adjusting component. The baffle is connected to the adjusting component and is located between the helical blades of a screw conveyor. The baffle is arranged along the axial direction of the screw conveyor. The adjusting component includes an adjusting rod that adjusts the height of the baffle.

[0006] The advantage of adopting the above technical solution is that by setting up baffles with adjustable height, different processing needs can be met. The baffles can be adjusted according to the changes in the solid content of the material, ensuring the solid phase extrusion dewatering effect while avoiding the problem of limited processing capacity caused by fixed channel height.

[0007] Furthermore, the spiral blade is provided with a limiting plate, the limiting plate is provided with a limiting groove, the limiting plates are symmetrically installed, and the baffle moves up and down along the limiting groove.

[0008] The advantage of adopting the above technical solution is that the setting of the limiting groove can restrict the position of the baffle, making it convenient for the baffle to move up and down, while fixing the position of the baffle during the process of the baffle squeezing the material, thus ensuring the squeezing and dewatering effect.

[0009] Furthermore, a sealing strip is installed inside the limiting groove.

[0010] The advantage of adopting the above technical solution is that the sealing strip ensures the sealing of the baffle and the limiting plate, and ensures the function of the baffle in squeezing the solid phase and intercepting impurities.

[0011] Furthermore, the adjusting assembly also includes a connecting seat for fixing the adjusting rod, the connecting seat being fixedly connected to the baffle, the adjusting rod being provided with a threaded rod, and the screw conveyor being provided with a threaded hole that mates with the threaded rod.

[0012] The advantage of adopting the above technical solution is that the connecting seat is used to fix the adjusting rod. By adjusting and rotating the adjusting rod, the position of the adjusting rod can be changed, and the position of the baffle can be adjusted without manual adjustment.

[0013] Furthermore, the drum is provided with an adjustment hole, the top of the adjustment rod is provided with an adjustment head, and the adjustment hole is provided with a sealing element.

[0014] The advantage of adopting the above technical solution is that by opening adjustment holes on the drum, the position of the baffle can be adjusted through the adjustment holes when it is necessary to adjust it, without disassembling the drum, which effectively reduces adjustment time. During production, the normal use of the drum is ensured by installing sealing parts.

[0015] Furthermore, the screw conveyor has a passage groove along its axial direction for passing through the baffle, with the lower end of the baffle located within the passage groove.

[0016] The advantage of adopting the above technical solution is that the lower end of the baffle extends into the screw conveyor by setting the groove, so that the baffle has a large height adjustment capability to ensure various usage needs. At the same time, the setting of the groove also serves as a limit, extending the service life of the baffle.

[0017] Furthermore, the two sides of the baffle are the contact surface and the back surface that come into contact with the material, and the connecting seat is detachably installed on the back surface of the baffle by screws.

[0018] The advantage of adopting the above technical solution is that by installing the connecting seat on the back of the baffle, the impact of solid material on the front can be avoided from affecting the height adjustment of the baffle, making the baffle adjustment smooth and convenient.

[0019] Furthermore, the drum is provided with a slag outlet and a liquid phase outlet, and the baffle is located near the slag outlet. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] like Figure 1-4 As shown, this utility model discloses a horizontal screw discharge sedimentation centrifuge with adjustable baffles, including a drum 1, a screw conveyor 2 installed inside the drum 1, and screw conveyor 2 being provided with screw blades 3; it also includes:

[0030] An adjustable baffle assembly includes a baffle 4 and an adjustment component. The baffle 4 is connected to the adjustment component and is located between the spiral blades 3 of the spiral conveyor 2. The baffle 4 is arranged along the axial direction of the spiral conveyor 2. The adjustment component includes an adjustment rod 5, which adjusts the height of the baffle 4.

[0031] The advantage of adopting the above technical solution is that, by setting an adjustable-height baffle 4, different processing needs can be met. The height can be adjusted according to changes in the solid content of the material, ensuring the solid-phase extrusion dehydration effect while avoiding the problem of limited processing capacity caused by a fixed channel height. When the solid content of the material is high, the height of the baffle 4 can be appropriately lowered to increase the channel space and improve the material throughput efficiency; when the solid content is low, the baffle 4 can be raised to enhance the extrusion effect and reduce the solid phase moisture content, thereby significantly improving the centrifuge's adaptability to materials with different characteristics and its separation efficiency.

[0032] In some implementation schemes, the spiral blade 3 is provided with a limiting plate 6, the limiting plate 6 is provided with a limiting groove, the limiting plates 6 are symmetrically installed and fixed to the opposite spiral blade 3 by welding, the baffle 4 moves up and down along the limiting groove, the limiting groove is set vertically, and its depth is adapted to the maximum adjustment stroke of the baffle 4, ensuring that the baffle 4 always moves along a straight trajectory during the adjustment process, avoiding the problem of uneven extrusion caused by offset.

[0033] Furthermore, a sealing strip is installed inside the limiting groove. The sealing strip is fixedly installed on both sides of the limiting groove. The material is wear-resistant and elastic rubber, which can always fit tightly against the side of the baffle 4 when the baffle 4 moves up and down, effectively preventing solid material from leaking from the gap between the baffle 4 and the limiting groove, and ensuring the compression and fixing ability of the baffle 4.

[0034] In some implementations, the adjustment assembly includes: a connecting seat 7, which is fixedly connected to the baffle 4; a threaded rod connected to the lower side of the adjustment rod 5; a threaded hole provided on the screw conveyor 2 that mates with the threaded rod; during installation, the threaded rod is screwed into the threaded hole; the adjustment rod 5 is rotatably mounted on the connecting seat 7; an adjustment head is provided at the top of the adjustment rod 5; the adjustment head is provided with a hexagonal groove; an adjustment hole 11 is provided on the drum 1; the adjustment hole 11 is provided with a sealing element; the sealing element is detachable and installable; when the position of the baffle 4 needs to be adjusted, a hexagonal wrench is inserted into the drum 1 through the adjustment hole 11, and the adjustment head is rotated to change the height of the adjustment rod 5, thereby moving the connecting seat 7 and completing the adjustment of the position of the baffle 4 without disassembling the drum 1, effectively reducing the adjustment time.

[0035] In some implementations, the screw conveyor 2 has a passage slot along the axial direction for passing through the baffle 4, with the lower end of the baffle 4 located in the passage slot, so that the baffle 4 has sufficient room to move when the height is adjusted, and can fully extend when adjusted to the highest position to meet the high extrusion requirements.

[0036] Furthermore, the two sides of the baffle 4 are the contact surface and the back side that come into contact with the material. The connecting seat is detachably installed on the back side of the baffle 4 by screws. The contact surface that comes into contact with the material plays a squeezing role on the solid phase.

[0037] Furthermore, the drum 1 is provided with a slag outlet 12 and a liquid phase outlet 13. The baffle 4 is close to the slag outlet 12. The drum 1 is also provided with a feed inlet and a drive device. The drive device drives the drum 1 and the screw conveyor 2 to rotate. The feed is fed through the feed inlet, and then the solid phase and liquid phase are separated under the action of centrifugal force. During the process of the screw conveyor 2 conveying the solid phase, the baffle 4 squeezes the solid phase to reduce the moisture content of the solid phase and intercept impurities.

[0038] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
