Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, and in particular to a digestion device. Background Technology

[0002] A water quality digester is a key piece of equipment for water sample pretreatment. Through high temperature, high pressure, or strong acid digestion, it transforms organic matter, suspended solids, and recalcitrant compounds in water samples into measurable forms, ensuring the accuracy of subsequent tests (such as COD, total phosphorus, and total nitrogen). Employing intelligent temperature control (PID regulation) and rapid heating technology, it shortens reaction time and improves testing efficiency. Suitable for environmental monitoring, wastewater treatment, drinking water safety, and industrial wastewater analysis, it is an indispensable pretreatment tool for water quality laboratories.

[0003] A search revealed that patent CN220625944U discloses a water quality testing digestion device. This device uses four sets of rotating stirring rods to agitate the water sample inside the container, causing the sample to flow and thus be heated evenly, improving digestion efficiency and quality. However, after digestion, although a cooling fan can cool the sample in the test tube, the test tube remains on the surface of the heating module, which cools very slowly, resulting in slow cooling of the test tube as well. Manually removing the test tube directly poses a risk of burns to workers. Furthermore, relying solely on the heating module to heat the sample from the outside results in low heating efficiency and a reaction rate that needs further improvement. Therefore, further improvements are required. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a digestion device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a digestion device, comprising a digestion instrument body, wherein the top of the digestion instrument body is provided with multiple heating holes, and a first heating module is built into each heating hole; a test tube is placed inside each heating hole, and a support assembly is provided matching the test tube; a vertical plate is fixed to the upper surface of the digestion instrument body near the heating holes, and a horizontal plate is fixedly connected to the top of the vertical plate; an electric telescopic rod is fixed to the upper surface of the horizontal plate; a housing is fixed to the bottom telescopic end of the electric telescopic rod; a stirring assembly and a heating assembly are installed inside and on the lower surface of the housing; a side box is fixed to the outer wall of the digestion instrument body, and a fan is fixed to one side of the side box.

[0006] Furthermore, the support assembly includes a support plate with multiple perforations in the middle for inserting test tubes, a handle fixed to one side of the support plate, and a heat insulation layer provided on the inner wall of the perforations.

[0007] Furthermore, the stirring assembly includes multiple driven shafts that penetrate the bottom wall of the housing and are rotatably connected to the housing via bearings. Each driven shaft has a stirring blade fixed at its bottom end, and the stirring blades are respectively located above multiple heating holes. The stirring assembly also includes a motor fixed to the top wall of the housing, and a drive shaft is fixed to the bottom output end of the motor. A drive gear is fixed to the surface of the drive shaft, and each driven shaft has a driven gear fixed to its top end. All driven gears mesh with the drive gear.

[0008] Furthermore, the heating assembly includes an annular plate fixed inside the housing, and a second heating module is fixed on the upper surface of the annular plate. Multiple heat-conducting rods are fixed on the lower surface of the annular plate. The multiple heat-conducting rods extend through the bottom wall of the housing and out of the housing, and the multiple heat-conducting rods are respectively located above multiple heating holes.

[0009] Furthermore, a cover plate is fixed to the lower surface of the housing.

[0010] Furthermore, the side box has a mesh opening on the side facing the fan.

[0011] The beneficial effects of this utility model are:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a digestion device is disclosed, including a digester body 1. The top of the digester body 1 is provided with multiple heating holes 2, and a first heating module is built into each heating hole 2. A test tube 3 is placed inside the heating hole 2, and a support assembly 4 is provided to match the test tube 3. A vertical plate 5 is fixed on the upper surface of the digester body 1 near the heating holes 2, and a horizontal plate 6 is fixedly connected to the top of the vertical plate 5. An electric telescopic rod 7 is fixed on the upper surface of the horizontal plate 6. A housing 8 is fixed at the bottom telescopic end of the electric telescopic rod 7. A stirring assembly 10 and a heating assembly 11 are installed inside the housing 8 and on its lower surface. A side box 12 is fixed on the outer wall of the digester body 1, and a fan 14 is fixed on one side of the side box 12.

[0023] In this embodiment, the digester body 1 adopts existing technology, and the electric telescopic rod 7, stirring assembly 10, heating assembly 11 and fan 14 are all controlled by the built-in controller of the digester body 1.

[0024] The support assembly 4 includes a support plate 41, with multiple perforations 43 in the middle for inserting test tubes 3. A handle 42 is fixed on one side of the support plate 41, and a heat insulation layer is provided on the inner wall of the perforations 43.

[0025] In this embodiment, the test tube 3 has a ring at the top, the diameter of which is larger than the diameter of the perforation 43. Therefore, when the test tube 3 is taken out through the support assembly 4, the test tube 3 is inserted into the perforation 43, and the ring provides support for the test tube 3. At this time, the entire support assembly 4 can be taken out using the handle 42, which facilitates the simultaneous insertion of multiple test tubes 3 into multiple heating holes 2, or the removal of the test tubes 3 from the heating holes 2. The design of the heat insulation layer prevents the temperature of the test tube 3 from being transferred to the support plate 41 and the handle 42.

[0026] The stirring assembly 10 includes multiple driven shafts 101 that penetrate the bottom wall of the housing 8 and are rotatably connected to the housing 8 via bearings. Each driven shaft 101 has a stirring blade 102 fixed at its bottom end. The stirring blades 102 are located above the multiple heating holes 2. The stirring assembly 10 also includes a motor fixed to the inner top wall of the housing 8. A drive shaft 104 is fixed to the bottom output end of the motor. A drive gear 105 is fixed to the surface of the drive shaft 104. Each driven shaft 101 has a driven gear 103 fixed to its top end. The driven gears 103 mesh with the drive gear 105.

[0027] After the motor drives the drive gear 105 to rotate, the drive gear 105 drives multiple driven gears 103 and multiple driven shafts 101 to rotate synchronously, thereby driving multiple stirring blades 102 to rotate.

[0028] The heating assembly 11 includes an annular plate 112 fixed inside the housing 8, and a second heating module 113 is fixed on the upper surface of the annular plate 112. A plurality of heat-conducting rods 111 are fixed on the lower surface of the annular plate 112. The plurality of heat-conducting rods 111 pass through the bottom wall of the housing 8 and extend to the outside of the housing 8. The plurality of heat-conducting rods 111 are respectively located above the plurality of heating holes 2.

[0029] In this embodiment, the second heating module 113 is the same as the first heating module of the digester body 1. The ring plate 112 is a metal plate, and heat dissipation vents are provided on the side wall of the housing 8. In use, the heat-conducting rod 111 can be inserted into the test tube 3. After the ring plate 112 is heated by the second heating module 113, the heat is transferred to the heat-conducting rod 111, and the sample inside the test tube 3 is added using the heat-conducting rod 111. Furthermore, in this embodiment, heat insulation is used between the housing 8 and the heat-conducting rod 111.

[0030] A cover plate 9 is fixed to the lower surface of the shell 8. When the shell 8 is lowered, the cover plate 9 can cover the surface of the test tube 3 to prevent the sample from overflowing from the test tube 3 during stirring.

[0031] The side box 12 has a mesh 13 on the side facing the fan 14. The mesh 13 can accelerate air convection and improve the cooling of the test tube 3 placed in the side box 12 by the fan 14.

[0032] Working principle: After adding the sample and reaction reagents into test tube 3, insert test tube 3 into the perforation 43 on the support plate 41. Then, use handle 42 to remove the entire support assembly 4 and insert test tube 3 into multiple heating holes 2. Activate the electric telescopic rod 7 to extend, causing the shell 8 to descend until the cover plate 9 is in contact with the top of test tube 3. At this time, the stirring blade 102 and the heat-conducting rod 111 are inserted into the test tube 3. Then, activate the first heating module and the second heating module 113 of the digestion instrument body 1. The first heating module heats the test tube 3 from the outside, while the second heating module 113 heats the inside of the test tube 3 through the ring plate 112 and the heat-conducting rod 111. At the same time, the motor drives the stirring blade 102 to rotate, achieving sample stirring. After digestion is completed, activate the electric telescopic rod 7 to shorten, causing the shell 8 to move upward and reset. At this time, multiple test tubes 3 can be removed simultaneously from the heating holes 2 through the support assembly 4 and placed into the side box 12. Activate the fan 14 to cool the test tubes 3. The heating holes 2 can then be used to digest the next batch of samples.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
