Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a glassware cleaning device for chemical analysis. Background Technology

[0002] Chemical experiments use a wide variety of glassware, such as measuring cups, beakers, test tubes, reagent bottles, conical flasks, etc., and these glasswares vary in size and shape. In order to facilitate the cleaning of glasswares after experiments, utility model patent application number CN202220920525.7 (hereinafter referred to as Patent Document 1) provides a glassware cleaning device for chemical analysis. In addition, utility model patent application number CN202320166623.0 (hereinafter referred to as Patent Document 2) also provides a glassware cleaning device. In Patent Document 1, the cleaning solution is only sprayed onto the inner wall of the vessel without any scrubbing action, resulting in poor cleaning quality. In contrast, Patent Document 2 incorporates multiple operations, including spraying the cleaning solution, scrubbing, and drying, significantly improving the cleaning quality. Therefore, Patent Document 2 has a better cleaning effect than Patent Document 1. However, Patent Document 2 only cleans the inner wall of the vessel, leaving the outer wall uncleaned. Furthermore, Patent Document 2 can only clean regularly shaped items such as measuring cups, beakers, or test tubes, and is not suitable for cleaning conical flasks or reagent bottles. Therefore, its application to cleaning vessels is limited and its applicability is poor. Utility Model Content

[0033] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0034] Please see Figure 1-13 In a preferred embodiment of this utility model, a glassware cleaning device for chemical analysis includes a housing 1, on which a lifting assembly 5 and a rotating drive are installed. The rotating drive is installed on the movable end of the lifting assembly 5 and moves up and down under the lifting action of the lifting assembly 5. A rinsing main pipe 2 is installed on the movable end of the lifting assembly 5. The lower section of the rinsing main pipe 2 is connected to the rotating drive and rotates relative to the movable end of the lifting assembly 5 under the action of the rotating drive. The outer wall of the rinsing main pipe 2 has a brush that extends to the top of the rinsing main pipe 2. The upper section of the rinsing main pipe 2 is also provided with several through holes. The lower end of the rinsing main pipe 2 is connected to one end of a connecting pipe. The other end of the connecting pipe is equipped with a three-way control valve. One port of the three-way control valve is connected to a rinsing pump through a rinsing liquid pipe 4, and the other port of the three-way control valve is connected to a heating gas source through a gas pipe 3.

[0035] The housing 1 is also equipped with a clamping brush assembly 7; the clamping brush assembly 7 has two clamping brushes 7.1 and a horizontal drive member 7.2 for driving the two clamping brushes 7.1 to move. The two clamping brushes 7.1 are respectively arranged on opposite sides of the flushing main pipe 2, facing each other. Each clamping brush 7.1 has a bristle structure on the side facing the flushing main pipe 2 and the opposite side. The side of the clamping brush 7.1 facing the flushing main pipe 2 also has several through holes. The interior of each clamping brush 7.1 is hollow, and its bottom is connected to the flushing pump through a liquid pipe 4.

[0036] It also includes an auxiliary brush 8 and a top clamping structure 9; the auxiliary brush 8 includes brushes of various shapes and specifications, with only one brush detachably mounted on the main flushing pipe 2 at a time; the top clamping structure 9 is mounted on the housing 1, and includes a top clamping brush 9.3 and a top lifting member 9.1 that drives the top clamping brush 9.3 to rise and fall. The top clamping brush 9.3 is rotatably mounted on the movable end of the top lifting member 9.1. The top clamping brush 9.3 is located directly above the main flushing pipe 2, and has a bristle structure on the side facing the main flushing pipe 2. Several through holes are also opened on this side. The interior of the top clamping brush 9.3 is hollow, and its upper end is also connected to the flushing pump through a liquid pipe 4.

[0037] This utility model, through the arrangement and combined use of the above-described structure, can achieve cleaning of the inner and outer walls and drying of the inner wall of various types and specifications of glassware 12. The cleaning methods are diverse, for example:

[0038] 1. For regular, slender glassware 12 such as measuring cups and test tubes, the glassware 12 is hung upside down on the rinsing main pipe 2. The two clamping brushes 7.1 of the clamping brush assembly 7 are used to clamp and fix the outer wall of the glassware 12 under the action of the horizontal drive component 7.2. Then, the rinsing pump is controlled to operate, and the cleaning solution is sprayed from the through hole of the rinsing main pipe 2 onto the inner wall of the glassware 12. Simultaneously, the rinsing main pipe 2 rotates under the drive of the rotation component, thereby rinsing the inner wall of the glassware 12. Figure 9 As shown. In addition, when the vessel 12 is long, the inner wall of the vessel 12 can be thoroughly rinsed by raising and lowering the rinsing main pipe 2 via the lifting component 5.

[0039] For vessels 12 with larger inner diameters, an auxiliary brush 8 can be installed to expand the radial range of the rinsing main pipe 2, achieving thorough cleaning of the vessel 12. In this case, the auxiliary brush 8 is a strip-shaped brush, such as... Figure 13 As shown in (a). In addition, this can also be achieved by replacing the flushing main pipe 2 with one of different diameters, that is, by detachably connecting the flushing main pipe 2 to the movable end of the rotating drive and the lifting assembly 5; the flushing main pipe 2 has various specifications, and each specification of the flushing main pipe 2 has a different thickness or length.

[0040] II. For cleaning wide-mouth beaker-shaped vessels 12, without installing auxiliary brushes 8, the clamping brushes 7.1 are used in conjunction with the rinsing main tube 2 for cleaning. Specifically, the top of the clamping brushes 7.1 is flush with the top of the rinsing main tube 2. The two clamping brushes 7.1 are brought close to the rinsing main tube 2 under the action of the horizontal drive component 7.2. The vessel 12 is then placed over the clamping brushes 7.1 and the rinsing main tube 2. The top clamping brush 9.3, under the action of the top lifting component 9.1, together with the rinsing main tube 2, clamps the vessel 12. Then, the two clamping brushes 7.1 are moved towards the horizontal drive component 7.2. Under the action of the bristles, the brush moves away from the main rinsing pipe 2 until the clamping brush 7.1 contacts the inner wall of the vessel 12. Then, the rinsing pump is activated, and the cleaning fluid is sprayed from the through hole of the main rinsing pipe 2 onto the inner wall of the vessel 12. At the same time, the main rinsing pipe 2 rotates under the drive of the rotating drive component, and the vessel 12 also rotates accordingly. The inner wall of the vessel 12 is then washed by the clamping brush 7.1. If the vessel 12 is long, it can also be raised and lowered by the lifting component 5 and the top lifting component 9.1, so that the clamping brush 7.1 can thoroughly wash the vessel 12. Figure 10 As shown.

[0041] III. For cleaning reagent bottles, conical flasks, and other glassware 12, a suitable auxiliary brush 8 needs to be installed. This auxiliary brush 8 includes an inclined section and a vertical section. The inclined section is further away from the main rinsing pipe 2 than the vertical section, and the vertical section is at the bottom and connected to the main rinsing pipe 2. During cleaning, the glassware 12 is hung upside down on the main rinsing pipe 2 and the auxiliary brush 8, and the outer wall of the glassware 12 is held and fixed by two clamping brushes 7.1. Then, the rinsing pump is controlled to run, and the cleaning solution is sprayed from the through-hole of the main rinsing pipe 2 onto the inner wall of the glassware 12. Simultaneously, the main rinsing pipe 2 rotates under the drive of the rotating component, allowing the auxiliary brush 8 to clean the inner wall of the glassware 12. Figure 11 As shown. In addition, when the vessel 12 is long, the inner wall of the vessel 12 can be thoroughly rinsed by raising and lowering the auxiliary brush 8 and the rinsing main tube 2 via the lifting component 5.

[0042] IV. When cleaning the outer wall of the vessel 12, the vessel 12 is fixed in place by the rinsing main pipe 2 and the top clamping brush 9.3. The two clamping brushes 7.1 are adjusted to contact the outer wall of the vessel 12. During rinsing, the rinsing pump runs, and the rinsing liquid is sprayed onto the outer wall of the vessel 12 through the through holes on the clamping brushes 7.1. At the same time, the rotating drive unit drives the rinsing main pipe 2, the top clamping brush 9.3, and the vessel 12 held by them to rotate. Under the action of rotation, the outer wall of the vessel 12 is rinsed by the clamping brushes 7.1 and cleaned. Figure 12 As shown. Similarly, when the vessel 12 is long, the outer wall of the vessel 12 can be thoroughly rinsed by lifting the top clamp brush 9.3, the rinsing main pipe 2, and the vessel 12 by lifting the lifting assembly 5 and the top lifting component 9.1.

[0043] The following embodiments provide specific configurations of each structure to fully illustrate the technical solution of this utility model.

[0044] Regarding the rinsing main pipe 2 of this utility model, the lower end of the rinsing main pipe 2 is detachably mounted on the movable end of the lifting assembly 5 via a main pipe mounting seat. The main pipe mounting seat is rotatably mounted on the movable end of the lifting assembly 5. The main pipe mounting seat is connected to the rotation drive component, and the connecting pipe communicates with the rinsing main pipe 2 through the main pipe mounting seat. In this way, the rinsing main pipe 2 and related modules are detachably connected by means of the main pipe mounting seat, and the detachable connection between the rinsing main pipe 2 and the main pipe mounting seat can be achieved by means of snap-fit, threaded connection, etc. Furthermore, a top brush is detachably mounted on the top of the rinsing main pipe 2 to perform a washing operation on the inner top of the container 12 when it is inverted. The detachable connection means that different top brushes can be used to match different containers 12, thereby performing a more comprehensive washing operation on the inner wall of the container 12.

[0045] In this embodiment, the rotation drive is a rotary motor, and the output shaft of the rotary motor is connected to the main mounting base via a transmission belt assembly, gear assembly, or other transmission components. The upgrade component can be an electric telescopic rod, a linear stepper motor, a motor-screw assembly, or the like. The accompanying drawings show a motor-screw assembly. Similarly, the top lifting component 9.1 of the top clamping structure 9 is also like this. This embodiment shows a linear stepper motor structure, but the present invention is not limited to this structure.

[0046] In this invention, the two clamping brushes 7.1 of the clamping brush assembly 7 can not only clamp the vessel 12, but also clean the inner and outer walls of the vessel 12, achieving multiple functions and improving the cleaning effect of the glass vessel 12. In this embodiment, the clamping brush 7.1 is connected to the horizontal drive member 7.2 via a vertical extension rod, and the connection between the clamping brush 7.1 and the vertical extension rod is detachable, for example, by snap-fit ​​or threaded connection. Furthermore, considering the different shapes of various glass vessels 12, in order to improve the cleaning effect of the outer wall, the top of the clamping brush 7.1 is an inclined surface, which slopes upward toward the rinsing main pipe 2, and the inclined surface has a bristle structure, which can tilt the outer wall of the vessel 12, making it very suitable for non-cylindrical vessels 12 such as conical flasks. In this embodiment, the clamping brush 7.1 is moved and clamped by a horizontal drive component 7.2. The horizontal drive component 7.2 can be a motor-lead screw assembly, an electric telescopic rod, or other structures. In this embodiment, a motor-lead screw assembly is provided.

[0047] The auxiliary brush 8 of this invention can assist the rinsing main pipe 2 in washing the inner wall of the vessel 12. Its structural forms are diverse, for example... Figure 13As shown in (a)-(c), the auxiliary brush 8 can be selected and installed according to the specific vessel 12. However, it should be noted that the auxiliary brush 8 of this utility model is not limited to the form given in the drawings, and can also be other structural forms. In this embodiment, the bottom end of the auxiliary brush 8 is provided with a plug block, and the lower section of the rinsing main tube 2 has a socket. The auxiliary brush 8 is detachably connected to the rinsing main tube 2 by inserting the plug block into the socket.

[0048] The top clamping structure 9 of this utility model works in conjunction with the rinsing main pipe 2 to clamp the vessel 12, thereby facilitating the auxiliary brush 8 to scrub the inner wall of the vessel 12 and facilitating the clamping brush 7.1 to scrub the outer wall of the vessel 12. Preferably, the top clamping brush 9.3 is detachably installed on the movable end of the top lifting component 9.1. Specifically, it can be detachably connected by means of snap-fit ​​or threaded connection (e.g., the top mounting seat 9.2 of the top clamping brush 9.3 is rotatably installed on the movable end of the top lifting component 9.1, the top mounting seat 9.2 is connected to the top clamping brush 9.3 through a threaded joint, and the top mounting seat 9.2 is rotatably connected to the liquid pipe 4 to prevent the liquid pipe 4 from rotating with the top mounting seat 9.2). It has a variety of specifications and sizes, so that the appropriate specification and size of the top clamping brush 9.3 can be selected according to the shape and size of the vessel 12, thereby thoroughly cleaning the vessel 12. In addition, to prevent the top clamp brush 9.3 from affecting the upside-down placement of the vessel 12 on the rinsing main pipe 2, the top clamp brush 9.3 is connected to the movable end of the top lifting member 9.1 via a connecting plate 9.4. The connecting plate 9.4 is rotatably set with the movable end, and the axis of rotation is parallel to the lifting direction of the top lifting member 9.1. In this way, the top clamp brush 9.3 is rotated away from the top of the rinsing main pipe 2 by rotation.

[0049] Furthermore, considering liquid splashing during the cleaning process, this embodiment has a water-blocking enclosure on the housing 1. The water-blocking enclosure is framed on the outside of the main rinsing pipe 2, the clamping brush 7.1, and the auxiliary brush 8. The water-blocking enclosure has a notch through which the movable end of the lifting assembly 5 passes and moves. A movable baffle 6 is installed at the movable end of the lifting assembly 5 at the notch, and the movable baffle 6 is provided on both the upper and lower sides of the movable end. The movable baffle 6 covers the notch, and the movable baffle 6 rises and falls with the movable end of the lifting assembly 5, which can block splashing to a certain extent.

[0050] In addition, preferably, a partition 10 and a collection tank 11 are installed on the housing 1. The partition 10 is hollow and has an opening for the flushing main pipe 2 to pass through. The movable ends of the clamping brush 7.1 and the lifting assembly 5 are both located above the partition 10. A collection tank 11 is also installed below the partition 10. The collection tank 11 is used to collect the liquid used for flushing, which is convenient for subsequent centralized treatment.

[0051] Finally, it should be noted that the accompanying drawings in the specification of this utility model do not provide detailed diagrams of pipe layout, flushing pump, heating gas source, etc. The specific layout can be optimized and designed according to actual needs, and no specific location restrictions are made here.

[0052] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
