Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal separators, in particular to a centrifugal separator for tartaric acid production. Background Art

[0002] Tartaric acid, also known as potassium dihydrogen tartrate, is a colorless crystalline solid that is often used as a food additive. It can be used as a leavening agent for flour, a nutritional supplement for yeast, a leavening agent for cakes, etc. When producing tartaric acid, a centrifuge is required to separate and purify the tartaric acid.

[0003] In the prior art, there is a patent document with a publication number of CN217017016U, which discloses a centrifugal separator for tartaric acid production, including a fixed seat, a bearing seat fixedly installed in the middle of the fixed seat, a shaft rod inlaid and installed in the middle of the bearing seat, a centrifugal cylinder fixedly installed on the top of the shaft rod, a universal ball bearing fixedly installed at the bottom of the centrifugal cylinder, and a motor fixedly installed at the bottom of the fixed seat. The patent document drives the shaft rod to rotate through the motor, thereby driving the centrifugal cylinder to rotate, and the internal tartaric acid can be centrifuged. The electromagnet block is energized by the PLC controller through the time relay, and the metal plate can be adsorbed. At this time, the metal plate, the slide bar and the brush bar move as a whole. At this time, the brush bar contacts the inner wall of the centrifugal cylinder, and the tartaric acid adhering to the inner wall of the centrifugal cylinder can be quickly cleaned. After the timing time is reached, the electromagnet block automatically loses power, and the rebound force of the spring can separate the brush bar from the inner wall of the centrifugal cylinder, reducing unnecessary wear of the brush bar. It is more practical and suitable for wide promotion and use.

[0004] The above-mentioned and prior arts have the following defects: in the process of separating tartaric acid, since components such as slide bars and brush bars are always immersed in the tartaric acid mixture, the slide bars and brush bars will hinder the centrifugal cylinder from driving the tartaric acid mixture to rotate, thereby affecting the centrifugal effect of the centrifugal cylinder and reducing the centrifugal efficiency of the centrifuge.

[0005] Therefore, a centrifuge for tartaric acid production is proposed. Utility Model Content

[0006] The utility model aims to solve the defect that components such as sliding rods and brush strips will hinder the centrifugal cylinder from driving the tartaric acid mixed liquid to rotate, and proposes a centrifugal separator for tartaric acid production.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a centrifuge for tartaric acid production, comprising a centrifuge, a cover detachably mounted on the surface of the centrifuge, a surface of the cover fixedly mounted and connected with a liquid inlet pipe, a motor fixedly connected to the surface of the centrifuge, a centrifugal drum rotatably connected to the inner wall of the centrifuge, an output end of the motor fixedly connected to the centrifugal drum, a cleaning structure provided on the surface of the centrifuge, the cleaning structure comprising a support plate, the support plate fixedly mounted on the upper end of the centrifuge, a fixed cover fixedly connected to the upper surface of the support plate, an electric push rod fixedly connected to the top inner wall of the fixed cover, a rack fixedly connected to the output end of the electric push rod, a gear rotatably connected to the lower surface of the support plate, the gear meshing with the rack, a splint fixedly connected to the arc surface of the gear, and a brush strip slidably connected to the inner wall of the splint.

[0008] The effect achieved by the above components is: by setting up the cleaning structure, when tartaric acid needs to be separated, it is possible to prevent components such as the brush strip from contacting the tartaric acid mixture, thereby ensuring that the centrifuge cylinder can normally accelerate the tartaric acid mixture and ensuring that the centrifugal efficiency of the centrifuge is not affected.

[0009] Preferably, the internal thread of the clamping plate is connected with a bolt, and the bolt passes through the clamping plate and abuts against the surface of the brush strip.

[0010] The effect achieved by the above components is: when the bolt is rotated and abuts against the surface of the brush strip, the bolt can limit the position of the brush strip.

[0011] Preferably, a fixing block is fixedly connected to the inner wall of the fixing cover, a limiting rod is slidably connected inside the fixing block, and the limiting rod is fixedly connected to the rack.

[0012] The effect achieved by the above components is that during the movement of the rack, the limit rod will slide along the fixed block following the rack, and the limit rod can limit the sliding path of the rack.

[0013] Preferably, a stopper is fixedly connected to the upper end of the limiting rod.

[0014] The effect achieved by the above components is that the movement of the limit rod will drive the stopper to move, and when the stopper contacts the fixed block, the fixed block will prevent the stopper from sliding further, thereby limiting the position of the brush strip.

[0015] Preferably, a drainage structure is provided on the lower surface of the centrifuge, and the drainage structure includes a rotating tube, the rotating tube is rotatably connected to the centrifuge, the rotating tube is communicated with the centrifuge, the arc surface of the rotating tube is fixedly connected to a perforated plate, the position of the centrifuge relative to the orifice plate is fixedly connected to an extension tube, a plug rod is slidably connected in the extension tube, and the size of the plug rod is adapted to the size of the orifice plate.

[0016] The effect achieved by the above components is: by setting the liquid discharge structure, when the mixed liquid thrown out by the centrifugal cylinder flows into the centrifuge, the discharge position of the mixed liquid can be adjusted, thereby facilitating the collection of the mixed liquid flowing out of the rotating tube, thereby improving the convenience of using the centrifuge.

[0017] Preferably, the arc surface of the insertion rod is sleeved with a spring, and two ends of the spring are fixedly connected to the insertion rod and the extension tube respectively.

[0018] The effect achieved by the above components is that when the spring contracts, the plunger will be inserted into the orifice plate with the help of the tension of the spring, thereby limiting the position of the orifice plate.

[0019] Preferably, a positioning hole is opened on the surface of the extension tube, a positioning rod is fixedly connected to the arc surface of the insertion rod, and the positioning rod is slidably connected to the positioning hole.

[0020] The effect achieved by the above components is: when the positioning rod is pulled upward, the positioning rod slides along the inner wall of the positioning hole, which drives the insertion rod to slide, so that the insertion rod is out of contact with the orifice plate, and the positioning rod facilitates the movement of the insertion rod.

[0021] Preferably, the vertical cross-section of the positioning hole is in a "J" shape.

[0022] The effect achieved by the above components is: since the vertical section of the positioning hole is "J"-shaped, when the positioning rod is stuck on the inner wall of the shorter part of the positioning hole, the position of the positioning rod can be restricted, thereby restricting the position of the insertion rod.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0035] like Figure 1-Figure 6 As shown, the utility model provides a centrifuge for tartaric acid production, including a centrifuge 1, a cover 2 is detachably mounted on the surface of the centrifuge 1, a liquid inlet pipe 3 is fixed to the surface of the cover 2 and connected, a motor 4 is fixedly connected to the surface of the centrifuge 1, a centrifugal cylinder 5 is rotatably connected to the inner wall of the centrifuge 1, an output end of the motor 4 is fixedly connected to the centrifugal cylinder 5, a cleaning structure 6 is provided on the surface of the centrifuge 1, and a liquid discharge structure 7 is provided on the lower surface of the centrifuge 1.

[0036] The specific configuration and function of the cleaning structure 6 and the drainage structure 7 will be described in detail below.

[0037] like Figure 3 and Figure 4As shown, the cleaning structure 6 includes a support plate 601, which is fixedly installed on the upper end of the centrifuge 1. The upper surface of the support plate 601 is fixedly connected to a fixed cover 602, and the top inner wall of the fixed cover 602 is fixedly connected to an electric push rod 603. The output end of the electric push rod 603 is fixedly connected to a rack 604. The lower surface of the support plate 601 is rotatably connected to a gear 605, and the gear 605 is meshed with the rack 604. The arc surface of the gear 605 is fixedly connected to a clamping plate 606, and the inner wall of the clamping plate 606 is slidably connected to a brush strip 607. The clamping plate 606 is internally threaded with a bolt 608, and the bolt 608 passes through the clamping plate 606 and abuts against the surface of the brush strip 607. The bolt 608 is rotated. When the bolt 608 abuts against the brush After the surface of the brush strip 607 is formed, the bolt 608 reaches the function of limiting the position of the brush strip 607, the inner wall of the fixed cover 602 is fixedly connected with a fixed block 609, and the fixed block 609 is slidably connected with a limiting rod 610, and the limiting rod 610 is fixedly connected to the rack 604. During the movement of the rack 604, the limiting rod 610 will follow the rack 604 and slide along the fixed block 609, and the limiting rod 610 reaches the function of limiting the sliding path of the rack 604, and the upper end of the limiting rod 610 is fixedly connected with a stopper 611, and the movement of the limiting rod 610 will drive the stopper 611 to move, and when the stopper 611 contacts the fixed block 609, the fixed block 609 will prevent the stopper 611 from continuing to slide, thereby limiting the position of the brush strip 607.

[0038] like Figure 5 and Figure 6 As shown, the discharge structure 7 includes a rotating tube 71, which is rotatably connected to the centrifuge 1, and the rotating tube 71 is connected to the centrifuge 1. The arc surface of the rotating tube 71 is fixedly connected with a perforated plate 72. The position of the centrifuge 1 relative to the perforated plate 72 is fixedly connected with an extension tube 73. A plug rod 74 is slidably connected in the extension tube 73. The size of the plug rod 74 is adapted to the size of the perforated plate 72. A spring 75 is sleeved on the arc surface of the plug rod 74. The two ends of the spring 75 are fixedly connected to the plug rod 74 and the extension tube 73 respectively. When the spring 75 contracts, the plug rod 74 will be inserted into the perforated plate 72 with the help of the pulling force of the spring 75, so as to limit the position of the perforated plate 72 and extend the extension tube 73. A positioning hole 76 is provided on the surface of the extension tube 73, and a positioning rod 77 is fixedly connected to the arc surface of the insertion rod 74. The positioning rod 77 is slidably connected to the positioning hole 76. When the positioning rod 77 is pulled upward, the positioning rod 77 slides along the inner wall of the positioning hole 76, which drives the insertion rod 74 to slide, so that the insertion rod 74 is out of contact with the orifice plate 72. The positioning rod 77 serves to facilitate the movement of the insertion rod 74. The vertical cross-section of the positioning hole 76 is in a "J" shape. Since the vertical cross-section of the positioning hole 76 is in a "J" shape, when the positioning rod 77 is stuck on the inner wall of the shorter part of the positioning hole 76, the position of the positioning rod 77 can be limited, thereby limiting the position of the insertion rod 74.

[0039] The overall working principle is as follows: when tartaric acid needs to be separated, the tartaric acid mixture is poured into the centrifuge tube 5 through the liquid inlet pipe 3, and then the motor 4 is turned on. The rotation of the output end of the motor 4 drives the centrifuge tube 5 to rotate. The rotation of the centrifuge tube 5 accelerates the tartaric acid mixture and rotates the tartaric acid mixture. During this process, the brush strip 607 and other components will not contact the tartaric acid mixture, thereby ensuring that the centrifuge tube 5 can normally accelerate the tartaric acid mixture and ensure that the centrifugal efficiency of the centrifuge 1 is not affected. The excess solution in the tartaric acid mixture will be thrown out through the centrifugal cylinder 5. When the inner wall of the centrifugal cylinder 5 needs to be cleaned, the output end of the electric push rod 603 is controlled to extend, the output end of the electric push rod 603 will drive the rack 604 to move, the rack 604 will drive the gear 605 to rotate, the gear 605 will drive the splint 606 to move, the splint 606 will drive the brush strip 607 to move, and during the movement of the rack 604, the limit rod 610 will follow the rack 604 to slide inside the fixed block 609, and the limit rod 610 will follow the rack 604 to slide inside the fixed block 609. The positioning rod 610 has the function of limiting the sliding path of the rack 604. The movement of the positioning rod 610 will drive the block 611 to move. When the block 611 contacts the fixed block 609, the fixed block 609 will prevent the block 611 from continuing to slide, thereby limiting the position of the brush strip 607. At this time, the brush strip 607 will be against the inner wall of the centrifugal cylinder 5. As the centrifugal cylinder 5 continues to rotate, the brush strip 607 will clean the tartaric acid particles attached to the inner wall of the centrifugal cylinder 5. After cleaning, the output end of the electric push rod 603 is controlled to retract. When the brush strip 607 needs to be replaced, the bolt 608 is turned to disengage the bolt 608 from the brush strip 607, and then the old brush strip 607 is pulled out of the clamp plate 606, and the new brush strip 607 is inserted into the inner wall of the clamp plate 606, and then the bolt 608 is turned in the opposite direction. When the bolt 608 is against the surface of the brush strip 607, the bolt 608 reaches the function of limiting the position of the brush strip 607.

[0040] When the mixed liquid thrown out by the centrifugal cylinder 5 flows into the centrifuge 1, the mixed liquid will flow into the rotating tube 71, and the rotating tube 71 will discharge the mixed liquid. When the discharge position of the rotating tube 71 needs to be adjusted, the positioning rod 77 is pulled upward, and the positioning rod 77 slides along the inner wall of the positioning hole 76 to drive the insertion rod 74 to slide, so that the insertion rod 74 is out of contact with the orifice plate 72, and the positioning rod 77 can facilitate the movement of the insertion rod 74. The sliding of the insertion rod 74 will stretch the spring 75, so that the spring 75 is in a stretched state. When the positioning rod 77 slides to the top of the inner wall of the positioning hole 76, the positioning rod 77 is rotated. Since the vertical section of the positioning hole 76 is in a "J" shape, the positioning rod 77 is then slid downward to make the positioning rod 77 The positioning rod 77 is stuck in the inner wall of the shorter part of the positioning hole 76, thereby limiting the position of the positioning rod 77, and then limiting the position of the insertion rod 74. Then the rotating tube 71 can be rotated to adjust the discharge position of the rotating tube 71, so as to facilitate the collection of the mixed liquid flowing out of the rotating tube 71, thereby improving the convenience when using the centrifuge 1. After that, the positioning rod 77 is moved in the opposite direction. When the positioning rod 77 slides into the inner wall of the longer part of the positioning hole 76, the positioning rod 77 is released, and the spring 75 begins to contract. At this time, the insertion rod 74 will be inserted into the orifice plate 72 with the help of the pulling force of the spring 75, and the position of the orifice plate 72 is limited, thereby limiting the position of the rotating tube 71, ensuring that the rotating tube 71 can work stably.

[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
