Description

Technical Field

[0001] This utility model relates to the field of laboratory sample processing technology, specifically a laboratory sample processing device. Background Technology

[0002] As quality requirements for various chemical products become increasingly stringent, chemical companies are sampling and testing samples more frequently, resulting in a large number of chemical test samples remaining in chemical laboratories. Currently, chemical laboratories pre-treat sample bottles containing chemical reagents before cleaning them.

[0003] In the prior art, CN213669379U discloses a laboratory sample processing device. In actual use, the prior art relies solely on rubber protrusions to fix the reagent bottles during cleaning. During the cleaning process, a large amount of water stains accumulate on the surface of the reagent bottles. When the reagent bottles are subsequently tilted to pour out the internal cleaning water, the water forms a thin lubricating layer between the rubber block and the surface of the reagent bottle. This greatly reduces the friction between the two, resulting in insufficient clamping stability of the reagent bottles during subsequent tilting, and even causing the reagent bottles to slip. The stability and safety are poor. In view of this, we propose a laboratory sample processing device to solve the above problems. Utility Model Content

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Please see Figures 1-5As shown, a laboratory sample processing device includes a processing box 1. Two sealing doors 2 are slidably connected to the upper surface of the processing box 1. A placement plate 3 is provided inside the processing box 1, and a placement groove 4 is formed inside the placement plate 3. A filter screen is also provided at the bottom of the placement groove 4. For details, please refer to the published patent with publication number CN213669379U. Since it is prior art, it is not described or shown in detail here. A first cavity 5 is formed inside the placement plate 3, and the first cavity 5 is connected to the placement groove 4. Two bidirectional threaded rods 6 are rotatably connected inside the first cavity 5. The two bidirectional threaded rods 6 are fixedly connected, and connecting plates 7 are threaded onto the two opposite threaded ends of the bidirectional threaded rods 6. Clamping plates 8 are fixedly connected to the ends of 7. The clamping plates 8 are adapted to the reagent bottles to be cleaned. Rubber pads 9 are provided on the surfaces of the two clamping plates 8 that are close to each other. The rubber pads 9 further increase the stability of the clamping plates 8 when clamping the reagent bottles, thereby effectively preventing the reagent bottles from falling. A handle 10 is rotatably connected to the outside of the placement plate 3. The handle 10 rotates through the interior of the placement plate 3 and is fixedly connected to the bidirectional threaded rod 6. Guide grooves 11 are provided on both inner walls of the treatment box 1. A connecting component is provided inside the left guide groove 11. Two water pipes 12 are fixedly connected inside the treatment box 1. Water nozzles 13 are provided on the surface of the water pipes 12. The water nozzles 13 are arranged opposite to the placement groove 4.

[0024] In the above embodiment, the bottom of the treatment tank 1 is provided with an outlet for draining cleaning water, and the bottom wall of the treatment tank 1 is provided with a slope at the bottom of the middle high drain outlet, so as to facilitate the drainage of cleaning water from the inside of the treatment tank 1.

[0025] The connecting assembly includes a threaded rod 14, which is rotatably connected inside the left guide groove 11. A rotating rod 15 is rotatably connected inside the right guide groove 11. Guide blocks 16 are slidably connected inside both guide grooves 11, and both guide blocks 16 are fixedly connected to the placement plate 3.

[0026] The left guide block 16 is threaded onto the outer surface of the threaded rod 14, and the right guide block 16 is movably sleeved on the outer surface of the rotating rod 15. The rotation of the threaded rod 14 can drive the movement of the placement plate 3. At this time, the right guide block 16 will slide outside the rotating rod 15.

[0027] The lower surfaces of the two sealing doors 2 are provided with clearance grooves 18. The upper ends of the threaded rod 14 and the rotating rod 15 rotate through the interior of the processing box 1 and extend into the interior of the two clearance grooves 18 respectively. The upper ends of the threaded rod 14 and the rotating rod 15 are fixedly connected with gears 17.

[0028] The inner walls of the two clearance grooves 18 are fixedly connected with teeth 19, and the lower surface of the processing box 1 is provided with a drive assembly.

[0029] The teeth 19 inside the left relief groove 18 are fixedly connected to the rear inner wall of the relief groove 18, and the teeth 19 inside the right relief groove 18 are fixedly connected to the front inner wall of the relief groove 18, so that when the two gears 17 rotate in the same direction, the two sealing doors 2 can move closer to each other or further away from each other.

[0030] The drive assembly includes a motor 25, which is fixedly connected to the lower surface of the processing box 1. A second cavity 20 is provided inside the bottom plate of the processing box 1. The lower ends of the threaded rod 14 and the rotating rod 15 are rotatably inserted into the interior of the second cavity 20. The lower ends of the threaded rod 14 and the rotating rod 15 are rotatably connected to the bottom wall of the second cavity 20.

[0031] Among them, the motor 25 is also equipped with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail in this article.

[0032] Both the threaded rod 14 and the rotating rod 15 are fixedly fitted with sprockets 23 at their lower ends. The two sprockets 23 are externally connected to chains 24. The left threaded rod 14 is driven to rotate by the motor 25. At this time, the right rotating rod 15 will also rotate under the cooperation of the sprockets 23 and the chains 24. At this time, the two gears 17 can rotate synchronously, so that the two sealing doors 2 will also slide during the lifting and lowering of the placement plate 3.

[0033] A water tank 21 is fixedly connected to the right side surface of the treatment tank 1. A pump body is installed inside the water tank 21. Two connecting pipes 22 connected to the internal pump body are fixedly connected to the upper surface of the water tank 21. Both connecting pipes 22 penetrate into the interior of the treatment tank 1 and are respectively connected to two water pipes 12.

[0034] In the above embodiment, since there is a certain distance between the placement plate 3 and the sealing door 2, when the reagent bottle is placed on the upper part of the placement plate 3, during the process of the placement plate 3 descending and the sealing door 2 sliding towards the middle, there will be no collision between the sealing door 2 and the reagent bottle.

[0035] Working principle: When the staff needs to clean the reagent bottles, they first place the reagent bottles upside down inside the placement tank 4. At this time, the filter screen inside the placement tank 4 will support the reagent bottles. After the reagent bottles are placed one by one, turn the handle 10. The rotation of the handle 10 will drive the rotation of the bidirectional threaded rod 6. The rotation of the bidirectional threaded rod 6 will drive the movement of the connecting plate 7. The movement of the connecting plate 7 will drive the movement of the clamping plate 8. Finally, the clamping plate 8 clamps the reagent bottles. When the clamping plate 8 clamps the reagent bottles, the rubber pad 9 will also be deformed by force.

[0036] After clamping is complete, turn on the switch of motor 25. The rotation of the output shaft of motor 25 will drive the rotation of threaded rod 14. The rotation of threaded rod 14, together with the cooperation of sprocket 23 and chain 24, will drive the rotation of right rotating rod 15. At this time, the rotation of threaded rod 14 will drive the placement plate 3 to descend inside the processing box 1. At the same time, when threaded rod 14 and rotating rod 15 rotate, two gears 17 will also rotate. At this time, through the rotation of two gears 17 and the cooperation of teeth 19, two sealing doors 2 will slide towards the middle. When the placement plate 3 descends to the bottom, the two sealing doors 2 will be completely closed.

[0037] Subsequently, the staff started the pump inside the water tank 21. At this time, the cleaning water will enter the water pipe 12 through the connecting pipe 22 and be discharged through the spray head 13. The water sprayed from the spray head 13 will pass through the filter screen and enter the inverted reagent bottle, thus achieving the rinsing of the inside of the reagent bottle by the spray head 13. Since the reagent bottle is inverted, the cleaning water will fall into the bottom of the treatment box 1 and be discharged through the drain outlet.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
