[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0038] In order to enable those skilled in the art in this technical field to better understand the solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0039] The embodiment of the present utility model discloses an analyzer cleaning device. As shown in the attached Figure 2 and 3 figures, it includes a cleaning base 1 and a cleaning inner nest 2. The cleaning base 1 is cylindrical. A water storage tank is formed at the center of the cleaning base 1, and the water storage tank is a cylindrical tank. A base drain port 11 is provided through the bottom of the water storage tank. The water storage tank and the base drain port 11 are coaxially and through-connected, and they are distributed in a stepped manner. The inner diameter of the water storage tank is larger than the diameter of the base drain port 11. A base water inlet 12 is provided on the side wall of the cleaning base 1, and the base water inlet 12 penetrates along the radial direction of the cleaning base 1. A fixing ring is fixedly sleeved on the outside of the cleaning base 1 for fixing the cleaning base 1.
[0040] The cleaning inner nest 2 passes through the water storage tank and is blocked at the base drain 11, so that an annular cavity 3 is formed between the cleaning inner nest 2 and the water storage tank. The annular cavity 3 is communicated with the base water inlet 12. The purified water flowing in from the base water inlet 12 flows into the annular cavity 3. The outer side surface of the cleaning inner nest 2 abuts against the inner side wall of the base drain 11, so that the cleaning inner nest 2 blocks the base drain 11, realizing the separation of the annular groove and the base drain 11, avoiding the cross - pollution of the purified water in the annular cavity 3 and the sewage in the base drain 11, and preventing secondary pollution to the stirring rod 4 during the cleaning process.
[0041] It should be added that a sealing ring can be added between the cleaning inner nest 2 and the base drain 11 to ensure the sealing performance of the annular cavity 3 and avoid the communication between the annular cavity 3 and the base drain 11. The sealing ring can specifically be an O - ring, but is not limited thereto.
[0042] A cleaning cavity 21 is provided at the center of the cleaning inner nest 2 for cleaning the stirring rod 4. As shown in the appendix Figure 4 As shown, a plurality of cleaning water inlets 22 are provided on the side wall of the cleaning inner nest 2. All the cleaning water inlets 22 are used to connect the cleaning cavity 21 and the cleaning water inlets 22 of the annular cavity 3, so that the purified water in the annular cavity 3 flows into the cleaning cavity 21 through all the cleaning water inlets 22. All the cleaning water inlets 22 are evenly distributed in a circular ring shape to wash the stirring rod 4 from multiple angles. As a preferred embodiment, four cleaning water inlets 22 are specifically provided on the side wall of the cleaning inner nest 2. It should be noted that all the cleaning water inlets 22 are set higher than the cleaning water outlet 23, so that a water column of a certain height can be formed in the cleaning cavity 21 to soak the stirring rod 4. A cleaning water outlet 23 is provided at the bottom of the cleaning inner nest 2 for connecting the cleaning cavity 21 and the base drain 11, so that the sewage cleaned in the cleaning cavity 21 flows into the base drain 11 from top to bottom through the cleaning water outlet 23 and is discharged out of the cleaning base 1 through the base drain 11.
[0043] When the stirring rod 4 is inserted into the cleaning cavity 21, the purified water flows from the base drain 11 into the annular cavity 3, and then rushes into the cleaning cavity 21 through the cleaning water inlets 22, washing the stirring rod 4 in the cleaning cavity 21 and soaking the stirring rod 4 in the cleaning cavity 21 at the same time. The washing sewage flows from top to bottom to the bottom of the cleaning inner nest 2 until it flows into the cleaning water outlet 23 and is finally discharged through the base drain 11.
[0044] In the optimized analyzer cleaning device of the present utility model, the purified water in the annular cavity 3 is sprayed into the cleaning cavity 21 through the cleaning purified water port, which can not only change the original gushing - type cleaning to inner - spraying - type cleaning, but also upgrade the original single - soaking cleaning method to a dual cleaning method of washing and soaking, and can also ensure that the purified water before cleaning and the sewage after washing are completely separated during the cleaning process to avoid cross - pollution. The cleaning methods of the stirring rod 4 are increased, the cleaning method is more effective, so the stirring rod 4 is cleaner.
[0045] As shown in the attached Figure 4 figure, the center line of the cleaning water inlet 22 is inclined downward relative to the center line of the cleaning inner nest 2, so that the purified water in the annular cavity 3 rushes into the cleaning cavity 21 from top to bottom through the cleaning water inlet 22. After the purified water flow in the annular cavity 3 passes through the cleaning water inlet 22 for pressurization, it then rushes downward along the guidance of the cleaning water inlet 22 towards the stirring rod 4. The impact force exerted by the water flow on the stirring rod 4 increases, effectively washing away the residual substances attached to the surface of the stirring rod 4 and improving the cleaning effect.
[0046] As shown in the attached Figure 4 figure, a conical sleeve 24 is integrally provided at the bottom of the cleaning inner nest 2. The base drain port 11 is formed at the small-diameter end of the conical sleeve 24. The conical sleeve 24 is used to guide the sewage in the cleaning cavity 21 to converge to the base drain port 11 and reduce the water discharge volume of the base drain port 11, so that the cleaning cavity 21 can soak and clean the stirring rod 4. The diameter of the large-diameter end of the conical sleeve 24 is equal to the inner diameter of the cleaning cavity 21.
[0047] The sum of the flow rates of all the cleaning water inlets 22 is greater than the flow rate of the base drain port 11, so that the cleaning cavity 21 can store a water column of a certain height to soak the stirring rod 4.
[0048] A limiting groove is formed at the edge of the water storage tank. The water storage tank and the limiting groove are coaxially penetrated and distributed in a stepped manner. The inner diameter of the limiting groove is greater than the inner diameter of the water storage tank. A limiting ring 25 is integrally formed at the end of the cleaning inner nest 2. The diameter of the limiting ring 25 is greater than the diameter of the cleaning inner nest 2. The limiting ring 25 is matched with the limiting groove to axially limit the position of the cleaning inner nest 2 along the cleaning base 1.
[0049] A sealing member 5 is formed between the limiting groove and the limiting ring 25, which is used to seal the gap between the cleaning inner nest 2 and the cleaning base 1, so that the annular cavity 3 forms a closed cavity, avoiding foreign objects or sewage from flowing into the annular cavity 3 and affecting the cleaning effect, which is beneficial to improving the cleaning effect. The sealing member 5 can specifically be an O-ring, but is not limited thereto.
[0050] As shown in the attached Figure 3 figure, a diversion groove 26 is provided at one end of the cleaning inner nest 2 away from the cleaning water outlet 23. The diversion groove 26 extends along the radial direction of the cleaning base 1. An overflow hole 13 is provided on the side wall of the cleaning base 1. Both ends of the overflow hole 13 are connected to the diversion groove 26 and the base drain port 11 respectively. When the liquid level in the cleaning cavity 21 is too high, the sewage overflowing from the top of the cleaning cavity 21 overflows to the diversion groove 26, and then the diversion groove 26 guides the sewage to the overflow hole 13, and the sewage flows into the base drain port 11 along the overflow hole 13 and is discharged from the base drain port 11.
[0051] The overflow hole 13 has an L-shaped structure. The overflow hole 13 includes an axial groove extending along the axis of the cleaning base 1 and a radial groove extending along the radius of the cleaning base 1. The axial groove is vertically connected to the radial groove. One end of the radial groove is connected to the base drain port 11, and a plug 14 is detachably provided at the other end. The setting of the plug 14 not only facilitates the machining of the overflow hole 13 but also facilitates the cleaning of the overflow hole 13.
[0052] As shown in the Figure 4 accompanying drawings, a flange ring 27 is integrally provided on the end face of the cleaning inner nest 2, and the diversion groove 26 is formed on the end face of the flange ring 27. The flange ring 27 abuts against the abutting surface provided on the end face of the cleaning base 1, and is used to define the position of the cleaning inner nest 2 relative to the axis of the cleaning base 1. The flange ring 27 is fixed to the abutting surface by locking screws, so that the relative position of the cleaning inner nest 2 and the cleaning base 1 remains unchanged and the connection relationship is stable.
[0053] As shown in the Figure 2 and 5 accompanying drawings, an inlet joint 6 is fixedly provided at the base water inlet 12, and a drain joint 7 is fixedly provided at the base drain port 11. Both the inlet joint 6 and the drain joint 7 are detachably connected, which is convenient for replacement and maintenance. The inlet joint 6 is used to connect an external water inlet pipe, and the drain joint 7 is used to connect an external drain pipe.
[0054] During the cleaning process of the analyzer cleaning device provided by the present utility model, it is divided into four steps:
[0055] Step 1, the stirring rod 4 stops rotating. The stirring rod 4 is inserted into the cleaning cavity 21. The clean water flowing in from the base drain port 11 converges in the annular cavity 3. The clean water in the annular cavity 3 flushes into the cleaning cavity 21 from top to bottom through the cleaning water inlet 22, flushes the stirring rod 4 in the cleaning cavity 21, and at the same time soaks the stirring rod 4 in the cleaning cavity 21. The flushed sewage flows from top to bottom to the cleaning water outlet 23 and is discharged through the base drain port 11, as shown in the Figure 7 accompanying drawings;
[0056] Step 2, after the stirring rod 4 is completely inserted into the cleaning cavity 21, the stirring rod 4 rotates. Since all the cleaning water inlets 22 of the cleaning inner nest 2 are set higher than the cleaning water outlet 23, a certain height of water column remains in the cleaning cavity 21, soaking and stirring and flushing the stirring rod 4, as shown in the Figure 8 accompanying drawings;
[0057] Step 3, during the process of the stirring rod 4 being lifted from the bottom of the cleaning cavity 21, the stirring rod 4 stops rotating. The clean water in the annular cavity 3 flushes the stirring rod 4 from top to bottom through the cleaning water inlet 22, as shown in the Figure 9 accompanying drawings;
[0058] Step 4: After the stirring rod 4 is lifted to the open mouth of the cleaning chamber 21, the stirring rod 4 starts to rotate. The stirring rod 4 uses the centrifugal force generated by its own rotation to throw out the residual substances adhering to the surface, as shown in Figure 10 shown.
[0059] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.
[0060] Specific examples are used in this article to elaborate on the principles and implementation manners of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
