Description

Technical Field

[0001] This invention relates to the field of cleaning, and more specifically to a turbid liquid tank for use in turbidity meter testing that is easy to clean. Background Technology

[0002] Turbid liquids typically refer to liquids with a high content of suspended particulate matter, such as liquids containing suspended solid particles or turbid substances. Turbid liquid storage tanks are containers used to store this type of liquid. They usually need to be cleaned regularly to ensure the cleanliness of the inside of the storage tank and the stability of the liquid quality. Because the liquid contains suspended substances, the cleaning of the storage tank may be relatively complex and requires special techniques and equipment to ensure the cleaning effect. The process of cleaning turbid liquid storage tanks may involve professional cleaning equipment such as high-pressure water guns, steam cleaners, and cleaning agent spraying systems, as well as cleaning agents suitable for this type of liquid.

[0003] The currently disclosed Chinese patent CN106040056B discloses an easy-to-clean industrial mixing device, including a mixing tank. The mixing tank has a feed inlet at the top center and a discharge outlet on the lower left side. The mixing tank contains a mixing chamber. Electric telescopic rods are fixedly connected to the top of the mixing tank on both sides of the feed inlet, symmetrically arranged around the central axis of the feed inlet. The telescopic ends of the electric telescopic rods penetrate the mixing tank and are fixedly connected to a cleaning ring inside the mixing chamber. A protective seat is provided in the gap between the cleaning ring and the mixing chamber. The protective seat is sleeved on the outside of the telescopic ends of the electric telescopic rods and fixedly connected to the top of the mixing chamber. A brush retaining ring is fixedly connected to the outer surface of the cleaning ring. A brush is fixedly connected to the brush fixing ring. The end of the brush away from the brush fixing ring contacts the cavity wall of the mixing chamber. A water inlet and a diversion groove are respectively opened on the cleaning ring. The water inlet is located above the diversion groove and communicates with the diversion groove. A diversion head communicating with the diversion groove is fixedly connected to the bottom of the cleaning ring. A water spray head is provided on the diversion head. A connecting seat is fixedly connected to the top of the mixing tank and to the left of the electric telescopic rod. A water injection pipe is connected to the connecting seat. A water inlet hole communicating with the connecting seat is opened in the tank body of the mixing tank. The end of the water inlet hole away from the connecting seat passes through the mixing tank and communicates with the telescopic pipe provided in the mixing chamber. The output end of the telescopic pipe communicates with the water inlet. A stirring device is provided inside the mixing chamber.

[0004] According to the aforementioned patent, the electric telescopic rod can push the cleaning ring up and down in the mixing tank during cleaning, resulting in a better cleaning effect. However, the cleaning process is still cumbersome, requiring the electric telescopic rod to drive it, and it cannot clean the bottom part of the mixing rod, resulting in incomplete cleaning. Therefore, there is a need for a cleaning mechanism that is driven by the mixing rod and ensures complete cleaning inside the tank. Summary of the Invention

The inner ring of the internal toothed ring is uniformly provided with a number of strip-shaped snap-fit ​​blocks that fit into the snap-fit ​​gaps around its circumference. When the strip-shaped snap-fit ​​blocks snap into the snap-fit ​​gaps between the corresponding two rectangular tooth blocks, the external toothed ring is in a state of rotating together with the stirring shaft along with the internal toothed ring.

[0010] Preferably, the upper end of the rectangular toothed block has a bevel extending from the middle to both sides, and the lower end of the strip-shaped card block has a rounded head.

[0011] Preferably, the upper end of the inner ring of the lifting collar is coaxially provided with an upper end ring, and the lower end of the inner ring of the lifting collar is coaxially provided with a lower end ring. The internal gear ring is located between the upper end ring and the lower end ring.

Detailed Implementation

[0028] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] See Figures 1-4As shown, a turbidity meter uses a turbidity tank that is easy to clean. The tank is mounted on a support 1 and consists of a tank body 2 and a tank cover 3. A stirring shaft 31 extending vertically downwards from the center of the tank cover 3 into the tank body 2 is provided. A hanging ring 4 is detachably attached to the top of the tank body 2. The tank cover 3 is supported on the top of the hanging ring 4 and fixedly connected to the tank body 2. A wall scraping mechanism 5 is provided around the inner wall of the tank body 2. The wall scraping mechanism 5 is rotatably connected to the hanging ring 4 and can rotate relative to the hanging ring 4 around the circumference of the tank body 2. A self-locking mechanism is provided between the wall scraping mechanism 5 and the stirring shaft 31. Mechanism 6, the self-locking mechanism 6 includes a docking part and a snap-fit ​​part. The docking part is fixedly set on the upper half of the stirring shaft 31, and the snap-fit ​​part is movably set on the wall scraping mechanism 5. The snap-fit ​​part can move relative to the docking part along the axial direction of the stirring shaft 31. The wall scraping mechanism 5 is provided with a lifting collar 7 coaxial with the stirring shaft 31. The lifting collar 7 can move vertically on the wall scraping mechanism 5. The lifting collar 7 is sleeved on the snap-fit ​​part. The hanging ring 4 is provided with a lifting driver 8 for driving the lifting collar 7 to move. When the snap-fit ​​part is connected to the docking part, the wall scraping mechanism 5 is in a state of rotating together with the stirring shaft 31.

[0030] The tank body 2 is fixed on the bracket 1. The side wall of the tank body 2 is provided with a water inlet 21 and the bottom of the tank body 2 is provided with a water outlet 22. The lower half of the stirring shaft 31 is provided with stirring blades 311 and the top of the tank cover 3 is provided with a drive motor 32 for driving the stirring shaft 31 to rotate.

[0031] The top of the tank body 2 has a detachable hanging ring 4. The tank cover 3 is supported on the hanging ring 4 and fixedly connected to the tank body 2. A stirring shaft 31 is vertically downward at the center of the tank cover 3 to stir the internal materials. Inside the tank body 2, a scraping mechanism 5 is arranged around its inner wall. This scraping mechanism 5 is rotatably connected to the hanging ring 4 and can rotate relative to the hanging ring 4 around the circumference of the tank body 2. When the stirring shaft 31 stirs the materials in the tank body 2, the connecting parts and the locking parts are in a disengaged state. At this time, the stirring shaft 31 rotates, while the scraping mechanism 5 is stationary. Since the stirring shaft 31 is rotating at high speed, in order to avoid the scraping mechanism 5 affecting the rotation of the stirring shaft 31 and to avoid scraping the materials, the scraping mechanism 5 is designed to prevent the material from being stirred by the material. The wall scraping mechanism 5 damages the inner wall of the tank 2. Therefore, the wall scraping mechanism 5 stops when the stirring shaft 31 stirs the material. When cleaning the inside of the tank 2, the lifting drive 8 drives the lifting collar 7 to move, so that the snap-fit ​​part approaches the docking part until the snap-fit ​​part connects with the docking part. The wall scraping mechanism 5 is in a state of rotating together with the stirring shaft 31, realizing the self-locking function. As the stirring shaft 31 rotates, the speed of the stirring shaft 31 is controlled to be uniform. The cleaning liquid is introduced into the tank 2 through the water inlet 21. Combined with the rotation cleaning of the inner wall of the tank 2 by the wall scraping mechanism 5, the cleaning of the tank 2 is completed. There is no need to open the tank cover 3 for cleaning, which achieves the effect of automatic cleaning. No additional drive source is required, saving energy.

[0032] See Figures 2-6 As shown, the scraping mechanism 5 is provided with multiple metal scraper strips 51 evenly distributed around the inner wall of the tank 2. The two ends of the metal scraper strips 51 extend to the top and bottom of the tank 2, respectively. The edges of the metal scraper strips 51 are provided with rubber scraper strips 52 that contact the inner wall of the tank 2. The top of the tank 2 is provided with an upper ring sleeve 511 that is fixedly connected to all the metal scraper strips 51. The bottom of the tank 2 is provided with a lower ring sleeve 512 that is fixedly connected to all the metal scraper strips 51. The upper ring sleeve 511 is coaxially sleeved on the lifting ring 7. A bearing 41 is connected between the upper ring sleeve 511 and the hanging ring 4. The lower ring sleeve 512 is coaxially sleeved on the lower end of the stirring shaft 31.

[0033] During the cleaning process, the metal scraper 51 rotates at a constant speed along the inner wall of the tank 2, while the rubber scraper 52 reduces wear on the inner wall of the tank 2. At the same time, the upper ring 511 and the lower ring 512 enable the scraping mechanism 5 to be effectively connected with the lifting ring 7 and the stirring shaft 31, thereby realizing the change of motion state and self-locking function of the scraping mechanism 5, maintaining the stability of the scraping mechanism 5, making the cleaning process more intelligent and efficient, while protecting the inner wall of the tank 2, and improving the service life and safety of the tank 2.

[0034] See Figures 2-7 As shown, a retaining strip 71 extends outward from the outer side of the lifting collar 7, and a retaining groove 5111 for the retaining strip 71 to engage is provided on the inner wall of the upper collar 511 along its axial direction. A bottom support 5112 is provided coaxially at the bottom of the inner ring of the upper collar 511 to prevent the lifting collar 7 from falling off.

[0035] The locking strip 71 extending from the outer side of the lifting collar 7 and the locking groove 5111 on the inner wall of the upper collar 511 cooperate to effectively restrict the rotation of the lifting collar 7 relative to the upper collar 511. At the same time, the bottom support 5112 at the bottom of the inner ring of the upper collar 511 can provide support for the lifting collar 7, prevent it from falling off, increase the stability of the structure, and ensure the normal operation of the wall scraping mechanism 5. When the lifting collar 7 rotates, the upper collar 511 can also be driven to rotate together, thereby realizing the operation of the wall scraping mechanism 5.

[0036] See Figures 3-8 As shown, the docking component is specifically an outer toothed ring 61, and the snap-fit ​​component is specifically an inner toothed ring 62. The outer ring of the outer toothed ring 61 has a number of rectangular toothed blocks 611 evenly arranged around its circumference. There is a snap-fit ​​gap between every two adjacent rectangular toothed blocks 611. The inner ring of the inner toothed ring 62 has a number of strip-shaped snap-fit ​​blocks 621 evenly arranged around its circumference, which fit into the snap-fit ​​gap. When the strip-shaped snap-fit ​​block 621 snaps into the snap-fit ​​gap between the corresponding two rectangular toothed blocks 611, the outer toothed ring 61 is in a state of rotating together with the inner toothed ring 62 and the stirring shaft 31.

[0037] The transmission connection between the outer toothed ring 61 and the inner toothed ring 62 is achieved through the engagement of the outer toothed ring 61 and the inner toothed ring 62. As the inner toothed ring 62 moves closer to the outer toothed ring 61 under the drive of the lifting sleeve 7, until the strip-shaped locking block 621 is engaged in the engagement gap formed between two adjacent rectangular toothed blocks 611, the inner toothed ring 62 and the outer toothed ring 61 are in a state of rotation together. With the start of the stirring shaft 31, the lifting sleeve 7 is indirectly driven to rotate through the inner toothed ring 62 and the outer toothed ring 61. The lifting sleeve 7 then drives the upper ring sleeve 511 to rotate, thereby realizing the scraping and cleaning of the inner wall of the tank 2 by the rubber scraper 52.

[0038] See Figures 7-9 As shown, the upper end of the rectangular toothed block 611 has a beveled edge 6111 extending from the middle to both sides, and the lower end of the strip-shaped card block 621 has a round head 6211.

[0039] The beveled edge 6111 at the upper end of the rectangular toothed block 611 makes it easier for the strip-shaped locking block 621 to find the correct position when inserted, and it can slide smoothly into the locking gap when locked. The round head 6211 at the lower end of the strip-shaped locking block 621 reduces wear and friction when in contact with the rectangular toothed block 611 during the locking process, thereby extending the service life of the locking parts.

[0040] See Figures 7-9 As shown, the upper end of the inner ring of the lifting collar 7 is coaxially provided with an upper end ring 72, and the lower end of the inner ring of the lifting collar 7 is coaxially provided with a lower end ring 73. The internal gear ring 62 is located between the upper end ring 72 and the lower end ring 73. The upper surface of the internal gear ring 62 contacts the upper end ring 72, and the lower surface of the internal gear ring 62 contacts the lower end ring 73. The internal gear ring 62 can rotate relative to the lifting collar 7. A torsion spring 721 sleeved on the internal gear ring 62 is fixedly connected between the internal gear ring 62 and the upper end ring 72.

[0041] When the internal gear ring 62 approaches the external gear ring 61, in order to ensure that the strip-shaped locking block 621 can be smoothly engaged in the locking gap, the internal gear ring 62 is able to rotate relative to the lifting collar 7 through the connection of the torsion spring 721 between the internal gear ring 62 and the upper ring 72, until the internal gear ring 62 is completely moved to a position flush with the external gear ring 61, and the engagement of the internal gear ring 62 and the external gear ring 61 is completed.

[0042] See Figures 7-10 As shown, the inner edge of the lower ring 73 is provided with an arc-shaped groove 731 around its circumference, and the bottom of the internal gear ring 62 extends downward with an arc-shaped block 732 that slides and engages with the arc-shaped groove 731.

[0043] When the stirring shaft 31 drives the outer gear ring 61 to rotate, the outer gear ring 61 drives the inner gear ring 62 to rotate. In order to ensure that the outer gear ring 61 rotates together with the lifting sleeve 7, the sliding range of the arc block 732 is limited by the arc groove 731, thereby limiting the rotation range of the inner gear ring 62 in the lifting sleeve 7. This prevents the rotation range of the inner gear ring relative to the lifting sleeve 7 from being too large, which could damage the torsion spring 721. The rotation of the inner gear ring 62 smoothly drives the lifting sleeve 7 to rotate together after the arc block 732 contacts the end of the arc groove 731.

[0044] See Figure 7 As shown, the lifting driver 8 is equipped with a magnetic suction component and a return spring 81. The magnetic suction component is located between the hanging ring 4 and the lifting collar 7, and the return spring 81 is located between the lifting collar 7 and the base 5112. When the return spring 81 is in the normal state, the inner toothed ring 62 is engaged with the outer toothed ring 61.

[0045] Under normal conditions, the function of the return spring 81 is to engage the inner gear ring 62 and the outer gear ring 61 together, so as to ensure that the lifting collar 7 can move with the rotation of the outer gear ring 61, thereby realizing that the scraping mechanism 5 and the stirring shaft 31 rotate together. Driven by the stirring shaft 31, the scraping mechanism 5 cleans the inner wall of the tank 2. The function of the magnetic suction component is to provide connection and transmission between the lifting collar 7 and the hanging ring 4, so as to realize the separation of the inner gear ring 62 and the outer gear ring 61. During the stirring process of the stirring shaft 31, the scraping mechanism 5 is in a stationary state to avoid the scraping mechanism 5 from affecting the inner wall of the tank 2.

[0046] See Figure 7 As shown, the magnetic suction assembly consists of a first electromagnetic ring 82 and a second electromagnetic ring 83. Both the first electromagnetic ring 82 and the second electromagnetic ring 83 are sleeved on the lifting collar 7. The first electromagnetic ring 82 is fixedly connected to the hanging ring 4, and the second electromagnetic ring 83 is fixedly connected to the lifting collar 7.

[0047] When the first electromagnetic ring 82 and the second electromagnetic ring 83 are excited by current, they generate a magnetic field, thereby providing connection and transmission between the hanging ring 4 and the lifting collar 7, so that the lifting collar 7 is attracted to the position in contact with the hanging ring 4, thereby realizing the separation of the inner toothed ring 62 and the outer toothed ring 61, ensuring the normal stirring function of the stirring shaft 31 on the material in the tank 2.

[0048] See Figures 2-5 As shown, a limiting groove 42 is provided on the inner edge of the hanging ring 4 along its axial direction. A limiting strip 421 is fixedly provided on the inner side of the can cover 3 and is slidably engaged in the limiting groove 42. When the can cover 3 is fixedly connected to the can body 2 and the limiting strip 421 is aligned with the limiting groove 42 and engaged therein, the hanging ring 4 is in a stationary state.

[0049] The limiting strip 421 fixed on the inner side of the can lid 3 is engaged in the limiting groove 42 in the hanging ring 4. After the can lid 3 is fixed to the can body 2, the hanging ring 4 is also fixed together, so as to prevent the hanging ring 4 from rotating together when the scraping mechanism 5 rotates, thus protecting the can body 2 and the can lid 3 from damage and enhancing the stability and safety of cleaning the can body 2.

[0050] This invention uses a stirring shaft 31 to drive a scraping mechanism 5 to clean the inner wall of the tank 2. When the connecting part and the snap-fit ​​part separate, the stirring shaft 31 rotates independently to stir the material at high speed. When the connecting part and the snap-fit ​​part connect, the stirring shaft 31 drives the scraping mechanism 5 to rotate together to scrape the inner wall of the tank 2 at a uniform speed. This makes cleaning more convenient and faster, reduces human intervention during the cleaning process, avoids damage to the inner wall of the tank 2, and avoids affecting the rotation state of the stirring shaft 31 during the stirring process, thus improving work efficiency.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
