[0003]
In view of the above-mentioned disadvantages of the existing ceramic pump in use, the ceramic rod easily collides with the ceramic core and is scrapped due to guidance errors, and provides a ceramic pump with a reasonable structure that can be cleaned and sterilized online. The ceramic rod and the ceramic The core body is tightly matched to avoid damage and scrap, save production costs, and ensure long-term stable operation of the ceramic pump

Embodiment Construction
[0025] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0026] Such as figure 1 , image 3 with Figure 4 As shown, the ceramic pump of the present invention is composed of a pump body, a reciprocating pump rod inside the pump body and a metering rod. The pump body includes a stainless steel shell 5 and a ceramic core 6 nested in the inner wall of the shell 5. There is a through step hole, the pump rod includes a ceramic rod 9 and a top clamping sleeve 11, the pump rod is inserted into the step hole from the top opening of the ceramic core body 6, and the metering rod is inserted into the step hole from the bottom opening. Such as figure 1 As shown, the upper part of the outer wall of the shell 5 is provided with a cleaning inlet 1, the middle part is provided with a liquid medicine inlet 2 and a medicine liquid outlet 3, and the lower part is provided with a cleaning outlet 4, and the medic...

The invention discloses a ceramic pump capable of being washed and sterilized on line. A penetrating step hole is formed in the center of a ceramic core body of the ceramic pump; a ceramic rod is divided into an upper rod, a middle rod and a lower rod from top to bottom; and the diameter of the upper rod is basically consistent with that of the lower rod, and is greater than that of the middle rod, so that the parts having different diameters, of the ceramic rod, are matched with the step hole to complete the operation of washing and sterilizing or filling liquid medicine. In the process of converting a washing and sterilizing condition into a liquid medicine filling condition, the diameter of the upper rod of the ceramic rod is accurately matched with that of a first hole of the ceramic core body, besides, integral materials of the ceramic rod are the same, and the thermal expansion coefficient of the upper rod used as a guide section is consistent with that of the lower rod, so that the situation that after expanding at high temperature, the ceramic rod cannot generate skew and deviation and is always coaxial with the center of the step hole can be guaranteed; and in the falling process of the ceramic rod, because of the guiding effect of the upper rod, the lower rod of the ceramic rod cannot collide with a hole opening step, so that the ceramic rod is prevented from being scrapped, the production cost is saved, and the long-term stable operation of the ceramic pump and the production line is guaranteed.
Description
technical field [0001] The invention relates to the technical field of pumps, in particular to an online cleaning and sterilization ceramic pump used in medicine and chemical filling. Background technique [0002] At present, plunger pumps are widely used in medicine, environmental engineering, petroleum and chemical industries. Because metal pumps have low hardness, poor wear resistance and corrosion resistance, and are not resistant to high temperatures, ceramic materials are used to make plunger pumps. . After the ceramic pump has been used for a period of time or needs to be switched to fill different liquid medicines, it needs to be cleaned and sterilized, see figure 1 It is a pump body of an existing precision ceramic pump that can be cleaned and sterilized online. The ceramic pump has four inlets and outlets on the pump body: a liquid medicine inlet 2, a medicine liquid outlet 3, and a cleaning inlet 1 and a cleaning outlet 4. When the pump rod moves up and down in ...
