It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The actual dimensions of the components in the figures are not necessarily the same, but rather the actual dimensions may be modified according to the actual situation in which they are used in order to clearly and clearly illustrate the particular structure of the utility model.

Example 1

As figure 1, this embodiment discloses a filtrating collection device, including the jar body, the tank deck of the jar body is equipped with vacuum suction mouth 7, vacuum suction mouth 7 connects the vacuum pump, and the vacuum pump is used for improving the vacuum degree of the jar body, and then guarantees vacuum filter's filter effect. The bottom of the tank body is provided with a filtrate suction port 5, the filtrate suction port 5 is connected with a filtrate pump, and the filtrate pump is used for pumping out filtrate in the tank body. The upper side wall of the tank body is provided with a filtrate inlet 9, and filtrate enters the tank body through the filtrate inlet 9 and flows out through a filtrate suction port 5.

The middle part of the tank body is provided with a transverse clapboard 2, the transverse clapboard 2 is arranged at the height position of 1/3-2/3 of the tank body, and the thickness of the transverse clapboard 2 is generally 18mm-24 mm. The tank body is divided into an upper tank body 1 and a lower tank body 4 by a diaphragm plate 2, the upper tank body 1 is positioned at the upper part of the tank body, so that the vacuum suction port 7 is arranged at the top of the upper tank body 1, and a filtrate inlet 9 is also positioned in the upper tank body 1. The upper tank body 1 is communicated with the lower tank body 4 through a valve 3 arranged on the diaphragm plate 2, and the valve 3 is in a closed state in a working state, so that the upper tank body 1 is used as a new tank body to participate in the work at the moment. Under the suction effect of the vacuum pump of the same condition, compared with the original filtrate collecting tank, the gas volume of the filtrate collecting tank required to be acted by the vacuum pump is smaller, the vacuum degree of the upper tank body 1 is higher at the moment, the higher vacuum degree enables the upper tank body 1 to form a region with higher vacuum degree, and the filtering efficiency of the vacuum filter is further improved. The setting method is simple, the material consumption is less, and the effect is obvious.

Meanwhile, in order to solve the problem that filtrate caused by higher vacuum degree is easy to reversely capture and enter the vacuum suction port, the filtrate inlet 9 of the tank body is arranged below the filtrate outlet of the vacuum filter, the height difference between the filtrate inlet 9 and the filtrate outlet is 400mm-800mm, namely, the two ends of a pipeline between the tank body and the vacuum filter have the height difference, and the technical effect of the method is that the initial speed of the filtrate entering from the filtrate inlet 9 is further improved.

The vacuum suction provided by the vacuum pump is affected by the distance, i.e. the farther from the vacuum suction opening 7, the smaller the vacuum suction. Through the initial speed that improves filtrating, filtrating can pass through the great region of vacuum suction rapidly, prevents that the vacuum from improving to lead to a large amount of filtrating to be inhaled vacuum suction mouth 7, and this kind of method need not to change the structure setting of original filtrating holding vessel by a wide margin, if adopt the method that increases the pump body and improve filtrating initial speed, the increase of the pump body can influence the effect of the other pump bodies of current system, and the cost is higher.
