Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, in particular to a centrifuge which is convenient to clean. Background Technique

[0002] A centrifuge is a machine that uses centrifugal force to separate the components in a mixture of liquid and solid particles or liquid and liquid. Its working principle is based on Newton's second law of motion, that is, the force acting on an object is equal to the mass multiplied by the acceleration. In a centrifuge, this force is the centrifugal force generated by high-speed rotation, which can cause substances with different densities or particle sizes to move outward at different rates, thereby achieving separation.

[0003] In the existing centrifuge, after discharging materials, a large amount of residues will remain on the inner wall of the centrifugal drum, and the staff needs to manually use brushes and sprayers for laborious cleaning, which is inconvenient to operate. Therefore, there is an urgent need for a centrifuge that is convenient to clean and has convenient operation. Content of the Utility Model

[0004] In order to overcome the disadvantage of inconvenient manual cleaning of the existing centrifuge, the utility model provides a centrifuge that is convenient to clean and has convenient operation.

[0005] The technical solution of the utility model: In order to solve the above technical problems, the utility model provides such a centrifuge that is convenient to clean and has convenient operation, which includes a support frame, a machine body, a sealing cover, a first guide rod, a motor, a connecting rod, a hinge block, a mounting block and a cleaning component. The support frame is provided with the machine body, the top of the machine body is symmetrically provided with the first guide rod, and the sealing cover is slidably installed on the first guide rod together. The machine body is divided into upper and lower parts. A motor is installed in the lower part of the machine body, and the output shaft of the motor is connected with the connecting rod through the hinge block. The mounting block is slidably installed in the upper part of the machine body through the connecting rod. At least one test tube slot is spaced in the mounting block, and at least one cleaning component for automatically cleaning the residues on the inner wall of the centrifuge body is symmetrically and rotatably installed in the connecting rod.

[0006] Preferably, the cleaning component further includes a first connecting plate, a rotating shaft, a second connecting plate, a second guide rod, a spring and a brush head. At least one rotating shaft is installed in the connecting rod, the first connecting plate is rotatably installed on the rotating shaft, the second guide rod is installed in the first connecting plate, the second connecting plate is slidably installed on the second guide rod, the spring is sleeved on the second guide rod, and the brush head is installed on the top of the second connecting plate.

[0007] Preferably, it further includes a third connecting plate and a baffle. The motor penetrates through the bottom of the machine body and is rotatably installed with the third connecting plate, and the baffle is installed at one end of the third connecting plate away from the motor.

[0008] Preferably, a drain pipe is further included. The upper part inside the machine body is provided with a drain pipe, and the end of the drain pipe is movably and sealingly connected to the baffle plate, which is used to prevent material leakage during the operation of the centrifuge or discharge residues during cleaning.

[0009] Preferably, a scraper is further included. At least one scraper is symmetrically installed on the hinge block and is used to push the residues on the upper part of the machine body towards the direction of the drain pipe, so as to be discharged through the drain pipe.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. By starting the motor, the output shaft of the motor drives the connecting rod to rotate through the hinge block, and then drives the first connecting plate on the rotating shaft to rotate accordingly, so that the second connecting plate in the first connecting plate slides along the second guiding rod. At this time, the spring is compressed under pressure, and the second connecting plate extends outwards, making the brush head closely adhere to the inner wall of the machine body. As the connecting rod continues to rotate, the brush head on the second connecting plate slides along the inner wall of the machine body, effectively removing residues and making the cleaning operation more convenient.

[0012] 2. By providing a scraper and a drain pipe, during the cleaning process, the scraper on the hinge block discharges the residues on the upper part of the machine body through the drain pipe, further improving the cleaning effect. Description of the Drawings

Detailed Embodiment

[0018] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0019] Embodiment 1: A centrifuge that is convenient for cleaning, as Figure 1 and Figure 2 shown, including a support frame 1, a body 2, a sealing cover 3, a first guide rod 301, a motor 4, a connecting rod 401, a hinge block 402, a mounting block 5 and a cleaning assembly. The support frame 1 serves as the foundation of the entire device, bearing and stabilizing other components to ensure the safe operation of the centrifuge. The body 2 is the main container, and its internal space is used to accommodate samples and perform centrifugal separation. The first guide rods 301 symmetrically installed at the top of the body 2 are used to guide the vertical movement of the sealing cover 3 to ensure its smooth lifting and lowering. The opening and closing of the sealing cover 3 are achieved through sliding cooperation with the first guide rods 301. During centrifugation, the sealing cover 3 prevents the sample from splashing out and ensures the safety of the operation; in the cleaning mode, the sealing effect of the sealing cover 3 helps to effectively utilize the cleaning liquid and prevent leakage. The interior of the body 2 is divided into upper and lower layers. A motor 4 is installed at the lower part of the body 2, which is the power core of the centrifuge. The motor 4 drives the connecting rod 401 and the cleaning assembly through rotation to achieve the dual functions of centrifugation and cleaning. The motor 4 is connected to the connecting rod 401 via the hinge block 402, and the hinge block 402 ensures the transmission of power. The connecting rod 401 transmits the rotational force of the motor 4 to the mounting block 5 and the cleaning assembly. Six test tube slots 501 are spaced apart in the mounting block 5 for fixing the sample tubes to be centrifuged. Eight cleaning assemblies for automatically cleaning the residues on the inner wall of the centrifugal body 2 are symmetrically and rotatably installed in the connecting rod 401, which can contact the inner wall of the body 2 in all directions to achieve automatic cleaning and reduce manual operation.

[0020] As Figure 3 and Figure 4As shown, the cleaning assembly further includes a first connecting plate 6, a rotating shaft 601, a second connecting plate 602, a second guide rod 603, a spring 604 and a brush head 605. Eight rotating shafts 601 are symmetrically installed inside the connecting rod 401. These rotating shafts 601 are responsible for receiving the rotational power from the motor 4 and transmitting the power to the cleaning assembly. A first connecting plate 6 is rotatably installed on each rotating shaft 601. The first connecting plate 6 is closely connected to the rotating shaft 601 and can move synchronously with the rotation of the rotating shaft 601, thereby indirectly driving the brush head 605 to perform the cleaning operation. A second guide rod 603 is installed inside the first connecting plate 6. The second guide rod 603 can ensure that the brush head 605 can move precisely and smoothly in the radial direction. A second connecting plate 602 is slidably installed on the second guide rod 603. The second connecting plate 602 converts the rotational motion of the first connecting plate 6 into the radial motion of the brush head 605, enabling the brush head 605 to effectively contact and clean the inner wall of the machine body 2, while avoiding deviation or jamming due to friction or collision during the cleaning process. A spring 604 is sleeved on the second guide rod 603. The spring 604 provides a resilience force for the second connecting plate 602 and the brush head 605 thereon, ensuring that after the cleaning operation is completed, the second connecting plate 602 can quickly reset to prepare for the next round of cleaning. The brush head 605 is installed on the top of the second connecting plate 602 and directly contacts the inner wall of the centrifugal machine body 2. Its soft and tough bristles can penetrate into the gaps to remove the residues on the inner wall of the machine body 2, ensuring the cleanliness and working efficiency of the centrifuge.

[0021] When the centrifuge needs to be cleaned, the staff needs to first take out the mounting block 5 from the machine body 2, and then slide the sealing cover 3 downward along the first guide rod 301 until it is completely closed to form a closed cleaning environment. Start the motor 4. The output shaft of the motor 4 drives the connecting rod 401 to rotate through the hinge block 402, and then drives the first connecting plate 6 on the rotating shaft 601 to rotate accordingly. As the connecting rod 401 rotates, the second connecting plate 602 in the first connecting plate 6 slides along the second guide rod 603. At this time, the spring 604 is compressed under pressure, and the second connecting plate 602 extends outwards, making the brush head 605 closely adhere to the inner wall of the machine body 2. As the connecting rod 401 continues to rotate, the brush head 605 on the second connecting plate 602 slides along the inner wall of the machine body 2, effectively removing the residues, making the cleaning operation more convenient.

[0022] Embodiment 2: On the basis of Embodiment 1, as Figure 1 and Figure 2As shown in the figure, it further includes a third connecting plate 7, a baffle 701, a drain pipe 8 and a scraper 403. The motor 4 penetrates through the bottom of the machine body 2 and is rotatably installed with the third connecting plate 7. The motor 4 is firmly connected to the bottom of the machine body 2 through the third connecting plate 7. One end of the third connecting plate 7 away from the motor 4 is installed with a baffle 701, which forms a movable seal with the drain pipe 8 during the normal operation of the centrifuge, effectively preventing material leakage and maintaining the cleanliness of the working environment. The upper part of the machine body 2 is provided with a drain pipe 8, and the end of the drain pipe 8 forms a movable seal connection with the baffle 701. During the operation of the centrifuge, this sealing structure effectively avoids material leakage and ensures operation safety. In the cleaning mode, the drain pipe 8 becomes the discharge port for discharging the wastewater and residues during the cleaning process, ensuring the cleaning effect, preventing residue accumulation and avoiding affecting subsequent operations. Six scrapers 403 are symmetrically installed on the hinge block 402, which are specifically used to remove the residues that are difficult to reach in the upper part of the machine body 2. When the cleaning mode is started, the scrapers 403 can effectively push the residues on the inner wall of the machine body 2 towards the direction of the drain pipe 8 by means of the rotation of the hinge block 402 and discharge them smoothly through the drain pipe 8, realizing automatic cleaning, greatly reducing manual operation and significantly improving the cleaning efficiency.

[0023] When the centrifuge rotates, the scraper 403 will move along the inner wall, pushing the residues towards the direction of the drain pipe 8, so as to discharge them through the drain pipe 8, avoiding the cumbersome and potential safety hazards of manual cleaning. The end of the drain pipe 8 forms a movable seal connection with the baffle 701, which can prevent material leakage during the normal operation of the centrifuge and keep the working environment clean and safe. During cleaning, the drain pipe 8 can collect and discharge the wastewater and residues generated during the cleaning process, avoiding accumulation in the machine body 2 and improving the cleaning efficiency and thoroughness.

[0024] The above embodiments only represent the preferred implementation modes of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
