Description

Technical Field

[0001] This utility model relates to the field of horizontal screw centrifuge drum technology, and in particular to a composite wear-resistant horizontal screw centrifuge drum. Background Technology

[0002] The rotor of a horizontal decanter centrifuge is the core component of the centrifuge. It is usually cylindrical in shape and is responsible for generating centrifugal force to separate solid substances from the liquid. When the rotor rotates at high speed, solid particles in the liquid are pushed towards the drum wall due to centrifugal force, while the lighter liquid flows towards the center.

[0003] Utility model CN218962951U discloses a scraper for a horizontal decanter centrifuge and a horizontal decanter centrifuge. The key technical points are: it includes at least one pair of base plates and a scraper main plate. The base plates are fixed to the outer surface of the centrifuge drum, and the scraper main plate is detachably connected to the base plates. The scraper main plate is provided with a scraping structure for scraping away slag from the inner wall of the centrifuge shell. In this utility model, the scraper main plate is detachably connected to the base plate by bolts. Therefore, after the polycrystalline diamond composite sheet wears down, the scraper main plate can be easily removed, and the polycrystalline diamond composite sheet can be rotated at a certain angle for continued use. The entire process is simple. Alternatively, the polycrystalline diamond composite sheet can be replaced, at most the scraper main plate can also be replaced, while the base plate does not need to be replaced, reducing waste and saving costs. In addition, the polycrystalline diamond composite sheet has excellent wear resistance and a long service life, which can protect the drum from damage for a long time.

[0004] Regarding the above-mentioned content, the following technical defects exist: The composite wear-resistant horizontal screw centrifuge is a solid-liquid separation device that uses centrifugal force generated by high-speed rotation to separate solid substances from liquids. The composite wear-resistant drum is the device responsible for centrifugal separation. The drum is shaped like a large cylinder with an internal mesh structure used to separate solid substances. The drum uses composite materials and wear-resistant design to improve its wear resistance and corrosion resistance during long-term use. In use, the material pipe to be processed can be connected to the centrifuge's feed pipe with bolts, allowing the liquid to be processed to be poured into the centrifuge. However, the process of connecting the centrifuge's feed pipe to the material pipe to be processed with bolts is cumbersome, and a wrench is required to tighten the bolts. This reduces the speed of connecting the two pipes and affects the overall performance of the centrifuge. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the process of connecting the feed pipe of the centrifuge to the feed pipe of the liquid to be processed by bolts is cumbersome and requires the use of a wrench to tighten the bolts, which reduces the speed of connecting the two pipes and affects the overall performance of the centrifuge.

[0006] To solve the above-mentioned technical problems, this utility model provides a composite wear-resistant horizontal screw centrifuge drum, comprising: a centrifuge body, a cover installed on the upper surface of the centrifuge body, a drum body installed on the inner wall of the centrifuge body, a feed pipe installed on one side of the centrifuge body, an adjustment mechanism provided on the side of the centrifuge body near the feed pipe, the adjustment mechanism including a fixed frame, the fixed frame being fixedly connected to one side of the centrifuge body, a first spring being fixedly connected to the bottom wall of the fixed frame, a slider being fixedly connected to one end of the arc surface of the first spring, the slider being slidably connected to the inner wall of the fixed frame, a contact frame being fixedly connected to one side of the slider, two rotating rods threaded through the inner wall of the contact frame, an adjuster being rotatably connected to one end of the arc surface of the rotating rod, a connecting rod being rotatably connected to one side of the adjuster, a pressing plate being rotatably connected to one end of the arc surface of the connecting rod, the pressing plate being rotatably connected to one end of the arc surface of the rotating rod, and a contact clamp being fixedly connected to the inner wall of the contact frame, the contact clamp being an elastic clamp with an arc-shaped cross-section.

It uses centrifugal force generated by high-speed rotation to separate solid substances from liquids. The composite wear-resistant drum body is responsible for centrifugal separation. The drum body resembles a large cylinder with an internal mesh structure for separating solid substances. The drum body utilizes composite materials and a wear-resistant design to improve its wear resistance and corrosion resistance during long-term use.

However, connecting the centrifuge body's feed pipe to the feed pipe of the liquid to be processed using bolts is cumbersome, and a wrench is required to tighten the bolts, which slows down the connection and affects the overall performance of the centrifuge body. In this case, an adjustment mechanism can be used instead of bolts to connect the feed pipe to the feed pipe. The adjustment mechanism simplifies the installation process, thereby improving connection efficiency and allowing the centrifuge body to be put into use more quickly.

[0015] The effect achieved by the above-mentioned components is that when the cover is opened, the angle of the opened cover can be limited by the auxiliary mechanism to avoid the cover colliding with one side of the centrifuge body under the influence of the outside world during the opening process, so as to prevent the contact point from being bumped. The auxiliary mechanism can improve the stability of the cover opening.

[0016] Preferably, an auxiliary block is fixedly connected to one end of the arc surface of the positioning rod, and the auxiliary block is funnel-shaped.

[0017] The effect achieved by the above components is that the auxiliary block facilitates the connection between the positioning rod and the inner wall of the limiting hole.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 5 The present invention provides a composite wear-resistant horizontal screw centrifuge drum, comprising: a centrifuge body 1, a cover 4 installed on the upper surface of the centrifuge body 1, a drum body 5 installed on the inner wall of the centrifuge body 1, a feed pipe 6 installed on one side of the centrifuge body 1, an adjustment mechanism 2 provided on the side of the centrifuge body 1 near the feed pipe 6, and an auxiliary mechanism 3 provided on one side of the cover 4.

[0032] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The adjusting mechanism 2 includes a fixed frame 201, which is fixedly connected to one side of the centrifuge body 1. A first spring 202 is fixedly connected to the bottom wall of the fixed frame 201. A slider 203 is fixedly connected to one end of the arc surface of the first spring 202. The slider 203 is slidably connected to the inner wall of the fixed frame 201. A contact frame 204 is fixedly connected to one side of the slider 203. Two rotating rods 205 are threaded through the inner wall of the contact frame 204. An adjuster 206 is rotatably connected to one end of the arc surface of the rotating rod 205. A connecting rod 207 is rotatably connected to one side of the adjuster 206. A pressing plate 208 is rotatably connected to one end of the arc surface of the connecting rod 207. Plate 208 is rotatably connected to one end of the arc surface of rotating rod 205. A contact clamp 209 is fixedly connected to the inner wall of contact frame 204. The contact clamp 209 is an elastic clamp with an arc-shaped cross-section. The composite wear-resistant horizontal screw centrifuge body 1 is a solid-liquid separation device that separates solid substances from liquids through centrifugal force generated by high-speed rotation. The composite wear-resistant drum body 5 is responsible for centrifugal separation. The drum body 5 resembles a large cylinder with an internal mesh structure for separating solid substances. The drum body 5 uses composite materials and a wear-resistant design to improve its wear resistance and corrosion resistance during long-term use. In operation, the material pipe to be treated can be connected to the feed pipe 6 of the centrifuge body 1 using bolts, allowing the liquid to be treated to be poured into the centrifuge body 1. However, connecting the feed pipe 6 of the centrifuge body 1 to the material pipe of the liquid to be treated using bolts is a rather cumbersome process, and a wrench is required to tighten the bolts, which slows down the connection of the two pipes and affects the overall performance of the centrifuge body 1. In this case, the adjusting mechanism 2 can be used instead of bolts to connect the material pipe to the feed pipe 6. The adjusting mechanism 2 simplifies the installation process, thereby improving the connection efficiency and allowing the centrifuge body 1 to be put into use more quickly. (Contact clamp 20) Two friction pads 210 are fixedly connected to the side of the feed pipe 6. The friction pads 210 have anti-slip grooves on one side. The friction pads 210 can improve the friction when the contact clamp 209 contacts the feed pipe 6. A contact plate 211 is fixedly connected to the side of the extrusion plate 208 near the feed pipe 6. The contact plate 211 has a rectangular cross section. The contact plate 211 can prevent contact damage when the extrusion plate 208 contacts the feed pipe 6. A guide rod 212 is fixedly connected to the bottom wall of the fixed frame 201. One end of the arc surface of the guide rod 212 slides through the inner wall of the slider 203. The guide rod 212 can improve the stability of the slider 203 sliding in the fixed frame 201.

[0033] In the embodiments of this utility model, please refer to Figure 4 and Figure 5The auxiliary mechanism 3 includes an adjusting strip 31, which is fixedly connected to one side of the cover 4. A limit hole 32 is provided on the side of the adjusting strip 31. A connecting block 33 is fixedly connected to one side of the centrifuge body 1. A positioning rod 34 slides through the inner wall of the connecting block 33. A second spring 35 is sleeved on one end of the arc surface of the positioning rod 34. The two ends of the second spring 35 are fixedly connected to the positioning rod 34 and one side of the connecting block 33, respectively. When the cover 4 is opened, the angle of the opened cover 4 can be limited by the auxiliary mechanism 3. To prevent the cover 4 from colliding with one side of the centrifuge body 1 under external influences during the opening process, thus avoiding collisions at the contact point, the auxiliary mechanism 3 can improve the stability of the cover 4 when opening. An auxiliary block 37 is fixedly connected to one end of the arc surface of the positioning rod 34. The auxiliary block 37 is funnel-shaped and can facilitate the connection between the positioning rod 34 and the inner wall of the limiting hole 32. A pull ring 36 is rotatably connected to the inner wall of the positioning rod 34, which can increase the speed of pulling the positioning rod 34.

[0034] The working principle of the composite wear-resistant horizontal screw centrifuge drum provided by this utility model is as follows: When it is necessary to connect the material tube and the feed pipe 6, align the material tube and the feed pipe 6. At this time, the contact frame 204 can be pulled upward. The movement of the contact frame 204 will drive the slider 203 to slide within the fixed frame 201. At this time, the first spring 202 will be deformed, and the contact clamp 209 installed in the contact frame 204 will come into contact with the surface of the material tube and the feed pipe 6. The contact clamp 209 itself will deform, thereby restricting the material tube and the feed pipe 6 within the contact frame 204. At this time, the rotating rod 205 can be rotated. The movement of the rotating rod 205 will drive the regulator 206 to rotate. The movement of the regulator 206 will drive the extrusion plate 208 to come into contact with one side of the material tube and the feed pipe 6 along with the movement of the rotating rod 205. Under the interaction of the two extrusion plates 208, the material tube can be fixed to one side of the feed pipe 6.

[0035] When it is necessary to limit the angle of the opened cover 4, pull the positioning rod 34. The movement of the positioning rod 34 will cause the second spring 35 to be stretched, at which time the cover 4 can be opened. The opening of the cover 4 will cause the adjusting strip 31 to move. Align the limiting hole 32 on the adjusting strip 31 with the positioning rod 34. At this time, the positioning rod 34 can be released. The second spring 35 will return to its original position and can be connected to the inner wall of the limiting hole 32 through the connecting block 33. At this time, the angle of the opened cover 4 can be limited.

[0036] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
