Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food and medicine packaging, in particular to an online cleaning ceramic filling pump. Background Art
[0002] Plunger pumps are essential fluid conveying equipment, widely used in a variety of fields, including industry, agriculture, construction, and mining. They draw in and pump liquids through the reciprocating motion of a plunger, and precisely control the flow rate by adjusting the plunger's stroke. This is crucial for processes requiring precise metering. Their compact structure and durable materials enable them to operate stably and for extended periods under harsh operating conditions.
[0003] The existing filling equipment is equipped with a large number of plunger ceramic pumps. When a filling batch of a certain solution is completed or another solution needs to be replaced to start a filling task, all the plunger pumps must be disassembled, cleaned, reinstalled and debugged before production can continue, which wastes time and reduces production efficiency. At the same time, when the solute concentration in the solution is too high or the solubility of the solute is reduced, crystallization will occur and cause problems such as pump jamming and pipeline blockage, reducing product quality and production efficiency. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an online cleaning ceramic filling pump which can prevent crystallization, ensure filling accuracy and facilitate pump rod reset.

[0028] Figures 1 to 4An embodiment of the utility model for online cleaning of ceramic filling pump is shown. The online cleaning ceramic filling pump of this embodiment includes a pump body 1 and a pump rod 2. The pump rod 2 is slidably arranged in the pump body 1. The pump body 1 is provided with a filling liquid inlet channel and a filling liquid output channel. The side wall of the pump body 1 is provided with an annular groove 3 and a plurality of cleaning channels 5 connected with the annular groove 3. The plurality of cleaning channels 5 are arranged at intervals along the circumference of the pump body 1. A support block 4 is formed between two adjacent cleaning channels 5. The supporting side wall of the support block 4 is flush with the inner side wall of the pump body 1. The pump body 1 is provided with a liquid inlet 12 and a liquid outlet 13 connected with the annular groove 3.
[0029] The filling and cleaning process of online cleaning ceramic filling pump is as follows:
[0030] 1) If Figure 2 As shown in a, the pump rod 2 is in the original position at this time;
[0031] 2) The pump rod 2 moves downward to pump liquid, such as Figure 2 As shown in b, when the pump rod 2 reaches the maximum pumping position, the pump rod 2 moves upward and filling can be carried out. During filling, pure water is introduced into the annular groove 3 through the liquid inlet 12 and output from the liquid outlet 13 to form a cycle;
[0032] 3) If Figure 2 As described in step c, the pump rod 2 continues to descend from the maximum pumping position, and the end of the pump rod 2 is still engaged with the side wall of the pump body 1. At this time, the cleaning liquid is introduced. The cleaning liquid can enter the channel through the filling liquid to clean the filling surface of the pump body 1 and the pump rod 2.
[0033] 4) After cleaning, the pump rod 2 continues to move downward until the end of the pump rod 2 is engaged with the support block 4. Figure 2 As shown in FIG. 4 , the cleaning liquid reaches the annular groove 3 through the cleaning channel 5 and is discharged through the liquid inlet 12 or the liquid outlet 13 .
[0034] The online cleaning ceramic filling pump continuously introduces pure water into the annular groove 3 through the liquid inlet 12 during the filling process and discharges it from the liquid outlet 13. During the continuous flow of pure water, the pump body 1 and the pump rod 2 are continuously cleaned to achieve the purpose of preventing crystallization. At the same time, the gap between the pump body and the pump rod is sealed to isolate the contact between the liquid and the air. During cleaning, the pump rod 2 is pulled so that the end of the pump rod 2 is supported by the support block 4. The cleaning liquid entering the pump through the filling liquid inlet and outlet channel 11 can be discharged from the liquid inlet 12 or the liquid outlet 13 through the cleaning channel 5. Cleaning can be achieved without disconnecting the pump rod 2 from the pump body 1 or removing the pump rod 2 from the pump body 1. After cleaning, the support block 4 can guide and support the movement of the pump rod 2 to the filling position, thereby facilitating the resetting of the pump rod 2.
[0035] Further, if Figure 4As shown, in this embodiment, the ring area of the support block 4 is larger than that of the cleaning channel 5, thereby further improving the supporting and guiding effect of the pump rod 2.
[0036] Further, if Figure 3 As shown, in this embodiment, an end of the support block 4 close to the annular groove 3 is provided with an inclined guide surface 41. It plays a pre-guiding role for the reset of the pump rod 2 and facilitates the discharge of the cleaning liquid.
[0037] Further, if Figure 1 As shown, in this embodiment, the liquid outlet 13 is arranged obliquely relative to the side wall of the pump body 1. The inclination angle of the liquid outlet 13 is α, 0<α<10. The liquid inlet 12 is located near the support block 4, and the liquid outlet 13 is located near the other end of the annular groove 3. This facilitates liquid discharge and prevents the cleaning liquid from being retained in the annular groove 3.
[0038] Further, if Figure 1 As shown, in this embodiment, the filling liquid inlet channel and the filling liquid outlet channel overlap, both forming a filling liquid inlet and outlet channel 11. This channel 11 is located at the end of the pump body 1 and is connected to the liquid dispenser 6 and the filling needle 7, respectively. During pumping, the liquid dispenser 6 delivers liquid medicine into the pump body 1 through the filling liquid inlet and outlet channel 11. During filling, the liquid medicine in the pump body 1 is discharged through the filling needle 7 for filling.
[0039] Further, if Figure 1 As shown, in this embodiment, a liquid inlet check valve 61 is provided between the liquid distributor 6 and the filling liquid inlet and outlet channel 11, and a liquid outlet check valve 71 is provided between the filling needle 7 and the filling liquid inlet and outlet channel 11. The liquid flows in one direction during both inlet and outlet, ensuring the accuracy of filling.
[0040] Further, if Figure 1 As shown, in this embodiment, the pump body 1 includes a pump sleeve 14 and an outer shell 15. The pump rod 2 is slidably disposed within the pump sleeve 14. The outer shell 15 is sleeved onto the outside of the pump sleeve 14. One end of the outer shell 15 is detachably connected to an end cap 16. The liquid inlet 12 and the liquid outlet 13 are both provided on the pump sleeve 14, and the filling liquid inlet and outlet channel 11 is provided on the end cap 16. This facilitates the assembly and removal of the end cap 16 and its replacement. Preferably, in this embodiment, the outer shell 15 and the end cap 16 are connected by a clamp 19. A sealing ring 8 is provided between the end cap 16 and the pump sleeve 14 to ensure a tight seal between the end cap 16 and the pump sleeve 14.
[0041] Further, if Figure 1 As shown, in this embodiment, the housing 15 is provided with a liquid inlet connector 17 and a liquid outlet connector 18 corresponding to the liquid inlet 12 and the liquid outlet 13, respectively, so as to facilitate the connection between the liquid inlet 12 and the liquid outlet 13 and the external pipeline.
[0042] Further, if Figure 1As shown, in this embodiment, the pump rod 2 is detachably connected to a handle 21 for pushing and pulling the pump rod 2 at the extended end. The pump rod 2 is convenient to move through the handle 21.
[0043] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations. Therefore, any simple modifications, equivalent variations, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the scope of protection of the present invention.
