DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] It should be noted here that: during the dilution process of the polymer reagent, the elastic support component, the vibration component and the control component cooperate with each other to make the support platform 401 vibrate and swing back and forth at the same time, thereby assisting the polymer reagent inside the feeding dish 402 to achieve the effects of promoting uniform mixing, accelerating dissolution and diffusion, reducing the formation of bubbles and precipitation, and improving fluidity and operability during the dilution process. In addition, during the swinging and vibration process, the swing amplitude of the support platform 401 can be independently adjusted and controlled according to the amount of polymer reagent and diluent injected into the feeding dish 402, so as to avoid the overflow of reagent and diluent caused by large swings when the feeding dish 402 is at a high capacity, thereby further ensuring the dilution effect.

[0033] Preferably, the elastic support assembly includes a support plate 501 arranged between the bearing platform 401 and the slide 103, two sets of sleeves 502 are symmetrically fixed on the slide 103, and a slide bar 503 is slidably connected to the two sleeves 502, one end of the slide bar 503 is fixed to the support plate 501, and a spring 504 is sleeved on the outer side of the two sets of sleeves 502, and the spring 504 is set against the support plate 501 and the slide 103, and the support plate 501 is connected to the bearing platform 401 through a connecting assembly;

[0034] It should be noted here that: the two sets of sleeves 502 and the slide rod 503 facilitate the telescopic connection between the support plate 501 and the slide 103, and the support plate 501 is supported by the spring 504, so that the support plate 501 can be raised and lowered autonomously as the volume of the polymer reagent and diluent injected into the feeding dish 402 changes.

[0035] Preferably, the connecting assembly includes a spherical groove 601 provided on the supporting plate 501, a sphere 602 matched with the spherical groove 601 is rotatably mounted on the spherical groove 601, a connecting rod 603 is fixed to the upper end of the sphere 602, and one end of the connecting rod 603 is fixed to the lower end of the bearing platform 401;

[0036] It should be noted here that: through the connection function of the spherical groove 601 , the ball 602 and the connecting rod 603 , the supporting platform 401 can be swingably connected above the supporting plate 501 .

[0037] Preferably, the vibration component includes a circular groove 701 opened on the sphere 602 and the connecting rod 603, a driving rod 702 is rotatably connected to the slide 103, one end of the driving rod 702 is located inside the circular groove 701 and fixed with a ball pin 704, a plurality of hemispherical protrusions 705 for pushing against the ball pin 704 are fixed inside the circular groove 701 in a ring array state, and two groups of hemispherical protrusions 705 adjacent to each other are staggered, a first motor 703 for driving the driving rod 702 is installed at the lower end of the slide 103, and a reset component for resetting the bearing platform 401 after swing driving is arranged on the support plate 501;

[0038] It should be noted that: the driving rod 702 is driven to rotate by the first motor 703. During the rotation of the driving rod 702, the ball pin 704 is driven to move inside the circular groove 701. During the rotation of the ball pin 704, the ball pin 704 is sequentially abutted against the multiple hemispherical protrusions 705 inside the circular groove 701. During the abutment between the ball pin 704 and the hemispherical protrusion 705, the connecting rod 603 and the supporting platform 401 at one end of the connecting rod 603 are vibrated by the abutment between the ball pin 704 and the hemispherical protrusion 705. During the process of the spherical protrusion 705 abutting against each other, the ball 602 is connected by rotating inside the spherical groove 601, so that the ball pin 704 abuts against the hemispherical protrusion 705, pushing the connecting rod 603 and the supporting platform 401 at one end of the connecting rod 603 to tilt. As the ball pin 704 rotates, when the ball pin 704 does not abut against the hemispherical protrusion 705, the connecting rod 603 and the supporting platform 401 at one end of the connecting rod 603 are reset through the reset assembly. Therefore, during the rotation of the driving rod 702, the supporting platform 401 vibrates and swings back and forth.

[0039] Preferably, the reset assembly includes a mounting ring 802 sleeved on the outside of the connecting rod 603, a rubber ring 803 for abutting against the connecting rod 603 for reset is provided between the mounting ring 802 and the connecting rod 603, the rubber ring 803 is fixed on the inner side of the mounting ring 802, and a plurality of support frames 801 for auxiliary support of the mounting ring 802 are fixed between the mounting ring 802 and the support plate 501;

[0040] It should be noted that during the swinging of the connecting rod 603 , the connecting rod 603 abuts against the inner side of the rubber ring 803 , so that the rubber ring 803 is deformed by force and generates elastic force. The elastic force of the rubber ring 803 facilitates the reset of the connecting rod 603 after movement.

[0041] Preferably, the control assembly includes a fixed ring 901 fixed to the outer side of the lower end of the sphere 602, and a baffle 902 for limiting the swinging fixed ring 901 is connected to the slide 103 through a sliding assembly, and a connecting rod 903 is provided between the baffle 902 and the support plate 501, and the two ends of the connecting rod 903 are respectively rotatably connected to the lower end of the support plate 501 and one side of the baffle 902;

[0042] It should be noted here that: the offsetting effect of the baffle 902 and the fixing ring 901 can reduce the swing amplitude of the connecting rod 603, the sphere 602 and the supporting platform 401, so the swing amplitude of the supporting platform 401 can be adjusted and controlled autonomously according to the amount of polymer reagent and diluent injected into the feeding dish 402.

[0043] Preferably, the sliding assembly includes a T-shaped slot 1001 opened on the baffle 902, a T-shaped plate 1002 is slidably connected to the T-shaped slot 1001, and the T-shaped plate 1002 is fixed above the slide 103;

[0044] It should be noted here that the movement of the rear baffle plate 902 subjected to force is guided by the T-slot 1001 and the T-plate 1002 .

[0045] Preferably, the sealing assembly includes a fixing plate 201, a sealing plate 202 for contacting the outside of the window 102 is fixed on one side of the fixing plate 201, the slide 103 is fixed on one side of the sealing plate 202, and a sealing strip 203 is installed on the side of the sealing plate 202 close to the diluter 101;

[0046] It should be noted here that: during the sliding of the slide 103 , the sealing strip 203 on the sealing plate 202 abuts against the outer side of the diluter 101 , thereby sealing the window 102 of the diluter 101 , facilitating the subsequent dilution vibration processing operation inside the diluter 101 .

[0047] Preferably, the moving assembly includes a U-shaped frame 302 fixed to the outside of the diluter 101, a transmission plate 301 is fixed to the lower end of the fixed plate 201, a screw rod 303 is rotatably connected to the U-shaped frame 302, the screw rod 303 and the transmission plate 301 are meshed with each other, a second motor 304 for driving the screw rod 303 is installed on the U-shaped frame 302, and a plurality of guide rods 305 are slidably connected to the transmission plate 301, and the guide rods 305 are fixed between the U-shaped frame 302 and the diluter 101;

[0048] It should be noted here that: the second motor 304 is used to drive the screw rod 303 to rotate. During the rotation of the screw rod 303, the transmission plate 301 is moved by the mutual meshing transmission between the screw rod 303 and the transmission plate 301 and the sliding guiding effect of the multiple guide rods 305. The movement of the transmission plate 301 drives the fixed plate 201 to move synchronously.

[0049] Preferably, the baffles 902 are provided in multiple groups, and the multiple groups of baffles 902 are evenly distributed around the fixing ring 901;

[0050] It should be noted here that: by using multiple groups of baffles 902, it is convenient to block and limit the swing of the connecting rod 603 in different directions.

[0051] In this scheme: a dilution device for a polymer reagent comprises the following steps:

[0052] During the dilution process of the polymer reagent, a specified amount of the polymer reagent is poured into the feeding dish 402. After the feeding of the polymer reagent is completed, the sliding table 103 is driven to slide from the window 102 to the inside of the diluter 101 through the moving component. During the sliding process of the sliding table 103, the sealing strip 203 on the sealing plate 202 is abutted against the outside of the diluter 101, and the window 102 of the diluter 101 is sealed and blocked, so as to facilitate the subsequent dilution vibration processing operation inside the diluter 101;

[0053] After the slide 103 is slid into the diluter 101, the auxiliary dilution liquid is transported to the inside of the feeding dish 402 through the diluter 101 to dilute the polymer reagent. During the dilution process, the driving rod 702 is driven to rotate by the first motor 703. During the rotation of the driving rod 702, the ball pin 704 is driven to move inside the circular groove 701. During the rotation of the ball pin 704, the ball pin 704 is sequentially abutted against multiple hemispherical protrusions 705 inside the circular groove 701. During the abutment between the ball pin 704 and the hemispherical protrusion 705, the connecting rod 603 and the supporting platform 401 at one end of the connecting rod 603 vibrate through the abutment between the ball pin 704 and the hemispherical protrusion 705, and the ball pin 704 is abutted against the hemispherical protrusion 705. During the process, the ball 602 rotates and connects inside the spherical groove 601, so that the ball pin 704 abuts against the hemispherical protrusion 705, pushing the connecting rod 603 and the supporting platform 401 at one end of the connecting rod 603 to tilt. As the ball pin 704 rotates, when the ball pin 704 does not abut against the hemispherical protrusion 705, the connecting rod 603 and the supporting platform 401 at one end of the connecting rod 603 are reset through the reset component. Therefore, during the rotation of the driving rod 702, the supporting platform 401 vibrates and swings back and forth. Through the vibration and reciprocating swing of the supporting platform 401, the polymer reagent inside the feeding dish 402 can achieve the effects of promoting uniform mixing, accelerating dissolution and diffusion, reducing the formation of bubbles and precipitation, and improving fluidity and operability during the dilution process.

[0054] During the dilution process, when a large amount of polymer reagent and diluent are injected into the feeding dish 402, the weight is increased, so that the load-bearing platform 401 and the support plate 501 are forced to move toward the slide 103. During the movement of the support plate 501, the connecting transmission action of each connecting rod 903 pushes each baffle plate 902 to be forced to move toward the fixed ring 901 to gather together, thereby reducing the distance between the baffle plate 902 and the fixed ring 901. By reducing the distance, during the swinging of the connecting rod 603 and the sphere 602, the offset action of the baffle plate 902 and the fixed ring 901 alleviates the swinging amplitude of the connecting rod 603, the sphere 602 and the load-bearing platform 401. Therefore, the swinging amplitude of the load-bearing platform 401 can be adjusted and controlled autonomously according to the amount of polymer reagent and diluent injected into the feeding dish 402, thereby avoiding the overflow of the reagent and diluent caused by the large swinging of the feeding dish 402 when the inside is at a high capacity, thereby further ensuring the dilution effect.
