Description

Technical Field

[0001] This utility model relates to the field of horizontal screw centrifuges, and in particular to a sight glass structure for horizontal screw centrifuges that facilitates observation. Background Technology

[0002] A horizontal screw centrifuge is a continuously operating centrifugal separation device that uses centrifugal force generated by high-speed rotation to achieve rapid separation of solid and liquid phases in a suspension. Horizontal screw centrifuges are quite common in existing technologies.

[0003] Existing technologies, such as the utility model patent with publication number CN209076918U, disclose a horizontal screw discharge sedimentation centrifuge for vegetable oil emulsification and separation. This patent uses a base with a lower chamber mounted on its upper surface. An upper chamber is sealed above the lower chamber, and an observation window is provided on the upper surface of the upper chamber. A main motor is installed on the upper surface of the base near the lower chamber, and an auxiliary motor is installed on the other side of the upper surface of the base near the lower chamber. This utility model incorporates an atomizing chamber and connecting pipes, utilizing high-temperature steam generated by heating pipes to sterilize the interior of the centrifuge after centrifugation. It also features a shock-absorbing mechanism and shock-absorbing pads; the downward pressure of the compression rod, combined with the shock absorbers, reduces the shaking generated during centrifugation, increasing the stability of the base. A heating mesh is installed to heat the vegetable oil raw materials inside the lower chamber, preventing condensation of the raw materials inside the centrifuge.

[0004] In the existing technology, when operators use horizontal screw centrifuges to separate materials, they can usually only rely on the detection results at the centrifuge outlet and their personal work experience to indirectly judge the internal operating conditions of the drum, such as the thickness of the liquid ring layer, the dryness of the sludge, the flocculation effect, and whether blockage has occurred. Because this judgment method heavily relies on outlet feedback, it has a significant lag and cannot reflect the real internal state in real time. This can easily lead to untimely process adjustments and a large amount of material waste. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where operators can only rely on outlet inspection results and experience to judge the internal state of a horizontal screw centrifuge, such as the thickness of the liquid ring and the dryness of the sludge. This method is characterized by delayed feedback, which can easily lead to untimely adjustments and material waste. Therefore, this invention proposes a sight glass structure for horizontal screw centrifuges that facilitates observation.

[0006] To solve the above-mentioned technical problems, this utility model provides a sight glass structure for a horizontal centrifuge that facilitates observation, comprising: a support frame and a replacement structure. A rotating drum is installed inside the support frame, and a screw conveyor is installed inside the rotating drum. A protective cover is rotatably connected to the upper surface of the support frame. An auxiliary structure is provided inside the protective cover. The auxiliary structure includes a viewing panel, a transparent panel, two connecting plates, and a fixing plate. The viewing panel is fixedly connected to the rotating drum and is made of tempered borosilicate glass. The two connecting plates are slidably connected to the protective cover. The transparent panel is fixedly connected to the protective cover. The fixing plate is fixedly connected to the protective cover. The two connecting plates are positioned close to one side of the rotating drum. A movable plate is fixedly connected to the side. A cleaning brush is installed on the side of the movable plate away from the connecting plate via a replacement structure. Two telescopic rods are fixedly connected to the side of the movable plate near the protective cover. The fixed ends of the telescopic rods are fixedly connected to the protective cover. Springs are fitted on the arc surfaces of the telescopic rods. The two ends of the springs are fixedly connected to the protective cover and the movable plate, respectively. A connecting plate is fixedly connected to the side of the two connecting plates away from the movable plate. A positioning groove is formed on the inner wall of the connecting plate. A handle is fixedly connected to the side of the connecting plate away from the connecting plate. A lead screw is rotatably connected to one side of the fixed plate. A locking plate is threaded onto the arc surface of the lead screw. The locking plate is slidably connected to the positioning groove.

[0007] The aforementioned components achieve the following effects: When personnel need to observe the working conditions inside the drum, they can directly observe the working conditions inside the drum through the transparent plate and the viewing plate. When personnel find that dust and impurities on the outer surface of the viewing plate affect their viewing experience, they can rotate the lead screw to make the clamp slide out of the inner wall of the positioning groove. Then, they can move the handle until the cleaning brush contacts the surface of the drum. At this time, the drum is in working condition, which makes it convenient for personnel to clean the dust and impurities attached to the outer surface of the viewing plate and also allows personnel to intuitively see the material condition inside the drum, reducing material waste.

[0008] Preferably, the inner wall of the card plate is slidably connected to two limiting rods, and the two limiting rods are fixedly connected to the fixing plate.

[0009] The effect achieved by the above components is that the limiting rod can limit the movement of the pallet, thereby improving the stability of the pallet during movement.

[0010] Preferably, an anti-slip sleeve is fixedly connected to the arc surface of the grip, and the cross-section of the anti-slip sleeve is a hollow circle.

[0011] The effect achieved by the above components is that the anti-slip sleeve can increase the friction between the person's hand and the handle, and can prevent the person from slipping when moving the handle.

[0012] Preferably, the arc surface of the spring is fitted with a bellows, and the two ends of the bellows are fixedly connected to the movable plate and the protective cover, respectively.

[0013] The effect achieved by the above components is that the bellows can protect the spring and prevent other substances from coming into direct contact with the spring, thus affecting the service life of the spring.

[0014] Preferably, the inner wall of the movable plate is provided with a replacement structure, which includes two connecting grooves, two connecting blocks, and two positioning blocks. The two connecting grooves are formed on the movable plate, the two connecting blocks are fixedly connected to the movable plate, and the two positioning blocks are fixedly connected to the movable plate. The inner wall of the positioning block is provided with an auxiliary groove. The inner walls of the two connecting blocks are rotatably connected with rotating rods. The arc surfaces at both ends of the rotating rods are provided with opposite threads. The arc surfaces of the rotating rods are threadedly connected with two baffles. The side of the baffles near the positioning blocks is fixedly connected with an insert plate. The inner wall of the connecting grooves is slidably connected with an installation block, and the two installation blocks are fixedly connected to a cleaning brush.

[0015] The effect achieved by the above components is as follows: when the cleaning brush is severely worn after long-term use and needs to be replaced, the operator can rotate the rotating rod to move the guide block and baffle away from the mounting block. Then, the operator can move the cleaning brush until the mounting block slides completely out of the inner wall of the connecting groove, which makes it convenient for the operator to replace the cleaning brush and improves the replacement efficiency.

[0016] Preferably, a guide block is fixedly connected to the inner wall of the insert plate near the auxiliary groove.

[0017] The effect achieved by the above components is that the guide block can guide the insert plate, making it easier for personnel to slide the insert plate into the inner wall of the auxiliary groove.

[0018] Preferably, the arc surface of the rotating rod is fixedly connected to a rotating column.

[0019] The effect achieved by the above components is that the rotating column allows personnel to easily rotate the rotating rod, which can improve the ease of operation for personnel.

[0020] Compared with related technologies, the sight glass structure for a horizontal centrifuge provided by this utility model, which facilitates observation, has the following beneficial effects: This invention provides a sight glass structure for a horizontal screw centrifuge that facilitates observation. By adding an auxiliary structure, when personnel need to observe the working condition inside the drum to determine whether feeding is necessary, the auxiliary structure allows personnel to directly observe the working condition inside the drum through a transparent plate and a viewing plate. Furthermore, the cleaning brush can be moved to clean dust and impurities adhering to the outer surface of the viewing plate, thereby improving the convenience of cleaning and allowing personnel to intuitively see the material condition inside the drum, reducing material waste.

[0021] By incorporating a replacement mechanism, when a cleaning brush becomes severely worn after prolonged use and needs to be replaced, personnel can quickly and easily replace the brush, thereby accelerating the replacement process and improving efficiency. Attached Figure Description

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.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figure 1 The present invention provides a sight glass structure for a horizontal screw centrifuge that is easy to observe, comprising: a support frame 1 and a replacement structure 4. A rotating drum 2 is installed inside the support frame 1, and a screw conveyor 6 is installed inside the rotating drum 2. A protective cover 5 is rotatably connected to the upper surface of the support frame 1. An auxiliary structure 3 is provided inside the protective cover 5. The replacement structure 4 is provided on the inner wall of the movable plate 315.

[0027] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The auxiliary structure 3 includes a visible panel 301, a transparent panel 302, two connecting plates 303, and a fixed plate 307. The visible panel 301 is fixedly connected to the drum 2 and is made of tempered borosilicate glass. The two connecting plates 303 are slidably connected to the protective cover 5. The transparent panel 302 is fixedly connected to the protective cover 5, and the fixed plate 307 is fixedly connected to the protective cover 5. A movable plate 315 is fixedly connected to the side of the two connecting plates 303 closest to the drum 2. A cleaning brush 314 is installed on the side of the movable plate 315 away from the connecting plates 303 via a replacement structure 4. Two telescopic rods are fixedly connected to the side of the movable plate 315 closest to the protective cover 5. 313, the fixed end of the telescopic rod 313 is fixedly connected to the protective cover 5. The arc surface of the telescopic rod 313 is fitted with a spring 312. The two ends of the spring 312 are fixedly connected to the protective cover 5 and the moving plate 315 respectively. The side of the two connecting plates 303 away from the moving plate 315 is fixedly connected to a connecting plate 304. The inner wall of the connecting plate 303 is provided with a positioning groove 306. The side of the connecting plate 304 away from the connecting plate 303 is fixedly connected to a handle 310. The side of the fixed plate 307 is rotatably connected to a lead screw 309. The arc surface of the lead screw 309 is threadedly connected to a clamping plate 305. The clamping plate 305 is slidably connected to the positioning groove 306. When personnel need to observe the working condition inside the drum 2, they can directly observe the working condition inside the drum 2 through the transparent plate 302 and the viewing plate 301. When personnel find that dust and impurities on the outer surface of the viewing plate 301 affect their viewing experience, they can rotate the lead screw 309 to make the clamping plate 305 slide out of the inner wall of the positioning groove 306. Then, the personnel can move the handle 310 until the cleaning brush 314 contacts the surface of the drum 2. At this time, the drum 2 is in working condition, which makes it convenient for personnel to clean the dust and impurities attached to the outer surface of the viewing plate 301 and also makes it convenient for personnel to see the material condition inside the drum 2 intuitively, reducing material waste. The inner wall of the clamping plate 305 is slidably connected to two limit rods 308, and the two limit rods 308 are fixedly connected to the fixing plate 307. The limiting rod 308 can limit the movement of the clamping plate 305, improving its stability during movement. An anti-slip sleeve 311 is fixedly connected to the arc surface of the handle 310; the anti-slip sleeve 311 has a hollow circular cross-section. The anti-slip sleeve 311 increases the friction between the user's hand and the handle 310, preventing slippage during movement. A bellows 316 is fitted onto the arc surface of the spring 312; both ends of the bellows 316 are fixedly connected to the moving plate 315 and the protective cover 5, respectively. The bellows 316 protects the spring 312, preventing direct contact with other substances and ensuring its lifespan. In the embodiments of this utility model, please refer to Figure 4The replacement structure 4 includes two connecting grooves 401, two connecting blocks 408, and two positioning blocks 403. The two connecting grooves 401 are formed on the moving plate 315. The two connecting blocks 408 are fixedly connected to the moving plate 315. The two positioning blocks 403 are fixedly connected to the moving plate 315. The inner wall of the positioning block 403 is provided with an auxiliary groove 404. The inner wall of the two connecting blocks 408 is rotatably connected with a rotating rod 409. The arc surfaces at both ends of the rotating rod 409 are provided with opposite threads. The arc surfaces of the rotating rod 409 are threadedly connected with two baffles 405. The side of the baffle 405 near the positioning block 403 is fixedly connected with an insert plate 406. The inner wall of the connecting groove 401 is slidably connected with an installation block 402. The two installation blocks 402 are fixedly connected to the cleaning brush 314. When the cleaning brush 314 shows severe wear after prolonged use and needs replacement, the operator can rotate the rotating rod 409 to move the guide block 407 and baffle 405 away from the mounting block 402. Then, the operator can move the cleaning brush 314 until the mounting block 402 completely slides out of the inner wall of the connecting groove 401, facilitating brush replacement and improving efficiency. The insert plate 406 is fixedly connected to the guide block 407 near the inner wall of the auxiliary groove 404. The guide block 407 guides the insert plate 406, allowing it to slide easily into the inner wall of the auxiliary groove 404. The rotating rod 409 has a fixedly connected rotating column 410 on its arc surface. The rotating column 410 allows for easy rotation of the rotating rod 409, improving ease of operation. The working principle of the sight glass structure for a horizontal decanter centrifuge provided by this utility model is as follows: When personnel need to separate materials using the horizontal decanter centrifuge, the materials are transferred to the inside of the rotating drum 2. Then, the rotating drum 2 is started to rotate at high speed. The separated materials are then transferred to the outside of the rotating drum 2 by the screw conveyor 6 inside the rotating drum 2. When personnel need to observe the working condition inside the rotating drum 2, they can directly observe the inside of the rotating drum 2 through the transparent plate 302 and the viewing plate 301. In situations where personnel notice dust and impurities on the outer surface of the visual panel 301 affecting their observation experience, they can first rotate the lead screw 309. The lead screw 309 will drive the clamping plate 305 to move away from the positioning groove 306. The clamping plate 305 will slide on the arc surfaces of the two limiting rods 308, which can limit the clamping plate 305 and improve its stability during movement, until the clamping plate 305 completely slides out of the inner wall of the positioning groove 306. Then, personnel... The operator moves the handle 310 downwards using the anti-slip sleeve 311. The anti-slip sleeve 311 increases the friction between the operator's hand and the handle 310, preventing slippage during movement. The handle 310 then moves the connecting plate 304 downwards, which in turn moves the two connecting plates 303 downwards. The connecting plates 303 then move the moving plate 315 downwards, which in turn moves the output end of the telescopic rod 313 downwards. The moving plate 315 also drives the bellows 316 and the spring 312 to stretch. The bellows 316 can protect the spring 312 and prevent other substances from directly contacting the spring 312 and affecting its service life. Then, the moving plate 315 also drives the cleaning brush 314 to move downward with the help of the replacement structure 4 until the cleaning brush 314 contacts the arc surface of the drum 2. At this time, since the drum 2 is rotating, the dust and impurities attached to the surface of the visible plate 301 can be removed.

[0028] Additionally, when the cleaning brush 314 shows severe wear after prolonged use and needs replacement, the operator can first use the rotating column 410 to rotate the rotating rod 409. The rotating column 410 facilitates the rotation of the rotating rod 409, improving ease of operation. Then, the rotating rod 409 moves the two baffles 405 away from the positioning block 403. The baffles 405 move the insert plate 406 away from the positioning block 403, and the positioning block 403 moves the guide block 407 away from the positioning block 403. The guide block 407 guides the insert plate 406, allowing personnel to easily slide the insert plate 406 into the inner wall of the auxiliary groove 404 until the guide block 407 and the baffle 405 are completely away from the side of the mounting block 402. Then, the personnel move the cleaning brush 314 away from the protective cover 5. The cleaning brush 314 drives the two mounting blocks 402 away from the connecting groove 401 until the mounting blocks 402 completely slide out of the inner wall of the connecting groove 401.

[0029] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
