Description

The device relates to devices for measuring the characteristics of liquid cleaners and can be used in industries that manufacture or use means for cleaning liquids.

The aim of the invention is to improve the measurement accuracy.

Figure 1 shows the hydraulic circuit of the device; Figures 2 and 3 show the initial and final positions of the tank when the hydraulic circuit of the tank-tank is broken.

The device consists of a tank 1 for a contaminated liquid, a pump 2, a cleaner 3 of liquid, instruments 4.5 for monitoring the purity of the fluid, pipes 6-10, a tank 11 for clean liquid placed inside the tank 1, and a bypass device (for example, a valve, a damper , tap, etc.) 12 to break the hydraulic chain tank-tank.

The device works as follows.

In the circulation cleaning mode, when the cleaner 3 is full (Fig. 1), the liquid from the tank 1 is pumped through the pump 3 through the cleaner 3 liquids to the tank 11, from where it passes through the bypass 12 to the tank 1. To determine the particle skip factor 3, the tank 11 is raised. Fluid from it through the bypass device 12 flows into the tank 1. Close the bypass device 12 (figure 2) and the contaminant is introduced into the tank 11, while the pump pumps the clean liquid and tank 1 through the cleaner 3 into the tank 11. The liquid jet from pipeline 10 and the stirrer (not shown) continuously stir the contaminant in an increasing volume of liquid in the tank 11. Lowering the liquid level in tank 1 and increasing the liquid level in tank 11 (FIG. 3) leads to lowering of the tank 11. At the time of approaching the bottom of the tank 11 to the bottom of tank 1, when after the break point ( tank 1) remains a minimum number of liquid and contaminant without air from the tank 1 does not fall into the conduit 6 opens the shutoff device 12. The flow of fluid

connects, i.e. the contaminated liquid from the tank 11 flows into the tank 1. During the pumping time, the cleaner 3 receives liquid with a constant concentration of the contaminant. At the same time quickly raise the tank 11 and close the bypass device 12 (figure 2). Cleaner fluid from the cleaner enters the ba

11. The time t determined from the condition t ---- (W0 is the volume of the cleaner, l; Q is the liquid supply, l / min), the concentration of contaminant particles at the entrance to the cleaner 3 (device 4) and at the exit from it (device 5). The skip ratio is defined as the quotient of the concentration of particles at the exit of the cleaner by the concentration of particles at the entrance to the cleaner. After sampling the control or completely transferring the liquid from the tank 1 to the tank 11, the overflow device 12 is opened through the cleaning / gel 3 liquid. In the future, the device can be operated in a circulating mode.
