Description

Technical Field

[0001] This application relates to the technical field of centrifugal oil extractors, and in particular to a feeding device for a centrifugal oil extractor. Background Technology

[0002] Currently, centrifugal oil separators are mechanical devices that utilize the principle of centrifugal force to remove oil from materials. They are widely used in industries such as food processing, chemicals, pharmaceuticals, and metallurgy. They separate liquids (such as oil, water, or other liquids) from solid materials through centrifugal force generated by high-speed rotation, thereby achieving the purpose of oil removal, dehydration, or liquid removal.

[0003] The core principle of a centrifugal oil extractor is centrifugal separation technology. The material is poured from the feed hopper at the top of the oil extractor into the inner cylinder of the oil extractor by an elevator. Then, the motor is started to drive the inner cylinder to rotate at high speed. Under the action of strong centrifugal force, the liquid (such as oil or water) carried in the material is separated out. Finally, the separated liquid is discharged through the drain port.

[0004] Because some materials carry a relatively large amount of liquid, the oil separator needs to spend more time during the oil removal process to ensure the separation effect between the liquid and the material, which reduces the oil removal efficiency and increases energy consumption. Utility Model Content

[0005] This application provides a feeding device for a centrifugal oil separator, which can improve the oil separation efficiency and reduce unnecessary energy consumption of the oil separator.

[0006] The feeding device for a centrifugal oil separator provided in this application adopts the following technical solution:

[0007] A feeding device for a centrifugal oil extractor includes a feeding hopper for installation outside the feed inlet of the oil extractor, with a discharge port formed at the bottom of the feeding hopper; a crossbeam is provided on the inner side wall of the feeding hopper, a liquid collection tray is provided on the crossbeam, a cover is provided above the liquid collection tray, the outer side wall of the cover is inclined downwards, and a plurality of drainage holes communicating with the liquid collection tray are provided through the cover, the outer diameter of the liquid collection tray is larger than the outer diameter of the discharge port.

[0008] Preferably, the upper surface of the cover is detachably fitted with oil-absorbing cotton.

[0009] Preferably, the oil-absorbing cotton is provided with a male hook and loop fastener, and the outer side wall of the cover facing the oil-absorbing cotton is provided with a female hook and loop fastener for bonding and fixing with the male hook and loop fastener.

[0010] Preferably, a slide rod is movably mounted on the crossbar, and a shock-absorbing spring is sleeved on the outside of the slide rod. The shock-absorbing spring extends and retracts along the sliding direction of the slide rod. One end of the shock-absorbing spring abuts against the slide rod, and the other end of the shock-absorbing spring abuts against the crossbar. The liquid collection tray is located at the top of the slide rod, and the shock-absorbing spring is used to push the liquid collection tray to rise away from the crossbar.

[0011] Preferably, a limiting ring is provided on the outer wall of the liquid collection tray, and the limiting ring is circumferentially surrounding the oil-absorbing cotton.

[0012] Preferably, a limiting cover is detachably fitted on the top of the feeding hopper, and a connecting rod is provided between the limiting cover and the limiting ring. The connecting rod is circumferentially arranged on the outer side wall of the limiting ring, and the connecting rod connects the limiting cover and the limiting ring to each other.

[0013] Preferably, a fixing ring is coaxially arranged on the outer circumferential wall of the feeding hopper, a positioning post is arranged on the side wall of the limiting cover facing the fixing ring, and a positioning hole is provided on the fixing ring for the positioning post to be inserted into the fixing ring.

During this process, the oil-absorbing cotton can also perform simple wiping of the material surface, further improving the liquid removal effect, reducing the oil removal burden on the subsequent oil extractor, increasing oil removal efficiency, and reducing unnecessary energy consumption of the oil extractor.

[0017] The shock-absorbing springs can buffer the material, thereby reducing the impact on the inner wall of the feed hopper when the material falls, and playing a role in protecting the material from collision.

[0018] By interlocking the positioning pins and positioning holes, the insertion cylinder can be accurately inserted and fixed on the top of the slide rod, thereby achieving the positioning function for the installation of the liquid collection tray. Attached Figure Description

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a feeding device for a centrifugal oil extractor.

[0026] Reference Figure 1 , Figure 2 as well as Figure 3 The feeding device of the centrifugal oil separator includes a feeding bin 1 fixedly installed outside the feed inlet of the oil separator. The bottom of the feeding bin 1 has a discharge port 10 for material to fall into the oil separator. A crossbeam 2 is fixedly installed on the inner wall of the feeding bin 1. A liquid collection tray 3 is detachably installed above the crossbeam 2 to collect the liquid carried in the material. A cover 4 is detachably installed above the liquid collection tray 3 to cover the top opening of the liquid collection tray 3. The outer wall of the cover 4 is inclined downwards, and the cover 4 has multiple drainage holes 40 that communicate with the interior of the liquid collection tray 3. The outer diameter of the liquid collection tray 3 is larger than the outer diameter of the discharge port 10. There is a gap between the outer wall of the liquid collection tray 3 and the inner wall of the feed hopper 1 for material to pass through. When the material falls onto the baffle 4, the material will fall into the lower discharge port 10 from the gap between the liquid collection tray 3 and the feed hopper 1 along the baffle 4 which is set at an angle downward under its own weight.

[0027] like Figure 3 , Figure 4 As shown, a screw 42 located inside the liquid collection tray 3 is fixedly installed on the central shaft of the cover 4. The bottom of the screw 42 is threaded into the liquid collection tray 3, and the cover 4 is fixedly connected to the inner bottom wall of the liquid collection tray 3 through the screw 42.

[0028] like Figure 3 , Figure 4As shown, three sliding rods 6 are movably threaded through the crossbar 2, arranged at intervals along the length of the crossbar 2. The sliding rods 6 slide vertically on the crossbar 2. A shock-absorbing spring 60 is fitted around the outside of each sliding rod 6, and the shock-absorbing spring 60 extends and retracts along the sliding direction of the sliding rod 6. The upper end of the shock-absorbing spring 60 abuts against the outer wall of the sliding rod 6, and the lower end of the shock-absorbing spring 60 abuts against the crossbar 2. A connecting tube 300, corresponding to each sliding rod 6, is fixedly installed at the bottom of the collection tray 3. The collection tray 3 is inserted and fixed from top to bottom to the top of its respective sliding rod 6 through the connecting tubes 300. The shock-absorbing spring 60 is used to push the collection tray 3 upwards away from the crossbar 2.

[0029] When the material falls onto the cover 4, the shock-absorbing spring 60 can buffer the material, thereby reducing the impact on the inner wall of the feed hopper 1 when the material falls, and playing a role in protecting the material from collision.

[0030] like Figure 3 , Figure 4 As shown, an oil-absorbing cotton 5 is detachably installed on the upper surface of the cover 4, and the oil-absorbing cotton 5 is in contact with the outer side wall of the cover 4. Multiple male Velcro straps 50 are fixedly installed on the bottom wall of the oil-absorbing cotton 5 facing the cover 4, and female Velcro straps 41 corresponding to each male Velcro strap 50 are fixedly installed on the outer side wall of the cover 4 facing the oil-absorbing cotton 5. The male Velcro straps 50 are used to adhere and fix themselves to their respective female Velcro straps 41. Through the mutual adhesion of the male Velcro straps 50 and female Velcro straps 41, the oil-absorbing cotton 5 can be fixedly installed on the upper surface of the cover 4, facilitating the installation and removal of the oil-absorbing cotton 5. The oil-absorbing cotton 5 can absorb liquid carried in the material, thereby further improving the liquid absorption effect.

[0031] When the amount of liquid absorbed by the oil-absorbing cotton 5 reaches saturation, the liquid can be discharged into the collection tray 3 through the drain hole 40. Furthermore, when material falls onto the oil-absorbing cotton 5, it will roll down along the downward-sloping cotton 5. During this process, the oil-absorbing cotton 5 can also perform simple wiping of the material surface, thereby further improving the liquid removal effect, reducing the oil removal burden on the subsequent oil separator, increasing oil removal efficiency, and reducing unnecessary energy consumption of the oil separator.

[0032] like Figure 3 , Figure 4 As shown, a limiting ring 30 is coaxially fixed on the outer wall of the liquid collection tray 3. The limiting ring 30 is circumferentially surrounding the oil-absorbing cotton 5. The limiting ring 30 is used to wrap the bottom edge of the oil-absorbing cotton 5, thereby effectively preventing the liquid on the oil-absorbing cotton 5 from falling outside the liquid collection tray 3.

[0033] like Figure 3 , Figure 4As shown, a limiting cover 7 is coaxially and detachably fitted onto the top of the feeding hopper 1, and the limiting cover 7 is inserted from top to bottom onto the top edge of the feeding hopper 1. Multiple connecting rods 8 are provided between the limiting cover 7 and the limiting ring 30, and each connecting rod 8 is circumferentially arranged on the outer side wall of the limiting ring 30. The connecting rods 8 are used to connect and fix the limiting cover 7 and the limiting ring 30. The limiting cover 7 is in a floating state under the elastic force of the shock-absorbing spring 60. When material falls onto the oil-absorbing cotton 5, the limiting cover 7 will swing up and down synchronously with the liquid collection tray 3.

[0034] like Figure 3 , Figure 4 As shown, a fixing ring 11 is coaxially fixed on the outer circumferential wall of the feed hopper 1. Two positioning posts 70 are fixedly installed on the bottom side wall of the limiting cover 7 facing the fixing ring 11, and the two positioning posts 70 are symmetrically arranged on both sides of the limiting cover 7. The fixing ring 11 has positioning holes 12 that correspond one-to-one with the positioning posts 70. The positioning holes 12 are used for the positioning posts 70 to be inserted and limited from top to bottom on the fixing ring 11. Through the mutual insertion of the positioning posts 70 and the positioning holes 12, it can be ensured that the insertion tube 300 is accurately inserted and fixed on the top of the slide rod 6, thereby realizing the positioning function of the liquid collection tray 3.

[0035] The operating principle is as follows: the oil-absorbing cotton 5 can absorb the liquid carried in the material, thereby further improving the liquid absorption effect. When the amount of liquid absorbed by the oil-absorbing cotton 5 reaches saturation, the liquid can be discharged into the collection tray 3 through the drain hole 40. In addition, when the material falls onto the oil-absorbing cotton 5, the material will roll down along the downward-sloping oil-absorbing cotton 5. During this process, the oil-absorbing cotton 5 can also perform simple wiping on the surface of the material, thereby further improving the liquid removal effect, reducing the oil removal burden on the subsequent oil degreasing machine, improving the oil removal efficiency, and reducing unnecessary energy consumption of the oil degreasing machine.

[0036] The shock-absorbing spring 60 cushions the material, reducing the impact on the inner wall of the feed hopper 1 when the material falls, thus providing anti-collision protection. The interlocking of the positioning pin 70 and the positioning hole 12 ensures that the insertion cylinder 300 is accurately inserted and fixed to the top of the slide rod 6, thereby achieving the positioning function for the installation of the liquid collection tray 3.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
