[specific embodiment]
By reference to the accompanying drawings the utility model is further elaborated, its product configurations and method can realize for a person skilled in the art.
The design of the utility model structure is based on two technical problems, one, and conventional emulsification equipment pressure control mode can't realize high operating pressure; Its two, the conventional emulsification material particular diameter can't reach nanoscale to be disperseed.
Therefore the emulsification chamber internal structure of existing high-pressure homogeneous emulsifying device is improved, set up the diamond nozzle in 100 μ m apertures and the Pyatyi ceramic reaction chamber structure of connecting.
High-pressure homogeneous emulsifying device after the improvement as shown in Figure 1, comprise hydraulic planger pump 1, check valve 3, Pressure gauge 4, emulsification chamber 6, heat exchanger 7, feed cup 2, discharging opening 8, hydraulic planger pump 1 plunger is connected with equipment trunk line one end, trunk line tap one end is connected with the blanking hole of funnel type feed cup 2 by a check valve 3, the other end of trunk line connects emulsification chamber 6 imports, tap one end is provided with Pressure gauge 4 on the trunk line between check valve 3 and the emulsification chamber 6, inside, described emulsification chamber is provided with a diamond nozzle 5 and Pyatyi pottery reaction chamber, be provided with the outlet of emulsification chamber at diamond nozzle to tap one end between the first order pottery reaction chamber, the outlet of described emulsification chamber links to each other with heat exchanger, and described heat exchanger is provided with water inlet, delivery port and discharging opening.
Internal structure its internal part shown in Fig. 1 enlarged drawing in emulsification chamber is a type and arranges, the diamond nozzle straight line in 100 μ m apertures connects the import of one-level pottery reaction chamber, one-level pottery reaction chamber outlet straight line connects the import of secondary pottery reaction chamber, secondary pottery reaction chamber outlet straight line connects three grades of ceramic reaction chamber imports, by that analogy, the outlet of Pyatyi pottery reaction chamber connects the tail end sealing in emulsification chamber.The flow direction of material in reaction chamber as shown in Figure 2, because reaction chamber afterbody sealing, therefore material injects one-level pottery reaction chamber by diamond nozzle, flows to successively secondary to Pyatyi pottery reaction chamber, is backflowed by Pyatyi and flows out the emulsification chamber to one-level pottery reaction chamber and enter heat exchanger.
