Abstract
The utility model discloses a device for preventing back suction. The device comprises a tank body and a tank cover, wherein the tank cover is arranged at a mouth part of the tank body, the tank cover is hermetically connected with the tank body, a liquid sealing device is arranged below the tank cover, a ventilation port is arranged on the tank cover, the liquid sealing device comprises a liquid storage container and at least one connecting pipe, the liquid storage container is hung below the tank cover, one end of each connecting pipe extends into the liquid storage container, the other end of each connecting pipe penetrates through the tank cover and is communicated with the outside, and a liquid drainage port is arranged at the bottom of the tank body. According to the device disclosed by the utility model, because the liquid sealing device is arranged below the tank cover, when liquid drainage is performed, the liquid storage container in the liquid sealing device is firstly filled with waste liquid, and the excess waste liquid flows into the tank body and is drained from the liquid drainage port at the bottom of the tank body.
Description
Technical field
The utility model relates to a kind of device that is used for chemical reaction, is specifically related to a kind of anti-suck device that prevents liquid or air suck-back.
Background technology
In airtight container, react, make internal pressure less than the external world when internal gas reduces, extraneous pressure can advance liquid in the container of gas minimizing, produce the suck-back phenomenon.At present, in the process of reaction effluent discharge,,, make the liquid in the equipment contaminated because the variation of internal pressure causes waste liquid or the air suck-back access arrangement that carries disease germs easily when when stopping discharge opeing.
The utility model content
Consider the problems referred to above of prior art, an aspect according to the utility model discloses a kind of anti-suck device; Comprise tank body and cover, cover is arranged on the oral area of tank body, and cover and tank body are tightly connected; It is characterized in that the below of said cover is provided with liquid seal device, described cover is provided with blow vent; Described liquid seal device comprises liquid storage container and at least one tube connector, and described liquid storage container is suspended on the below of cover, and an end of said tube connector stretches into and is used for discharge opeing in the liquid storage container; The other end of said tube connector passes cover and is communicated with the equipment that needs discharge opeing, and the bottom of said tank body is provided with leakage fluid dram.
As preferably, described tube connector has two.
As preferably, described liquid storage container is suspended on the below of cover through stainless steel strip, the two ends of said stainless steel strip respectively with liquid storage container and cover welding.
The purpose of the utility model is intended to design a kind of anti-suck device more handy, simple in structure.Compared with prior art; One of beneficial effect of the utility model is: through liquid seal device is set below cover, during discharge opeing, waste liquid at first is full of the liquid storage container in the liquid seal device; Submerged in the drain side of tube connector and be in the fluid-tight state in the liquid storage container; Excess liquid flows in the tank body again, discharges from the leakage fluid dram of tank base, when stopping discharge opeing; Because the drain side of tube connector is in the fluid-tight state, can prevent effectively that gas, liquid or the microorganism suck-back in sewer pipe or the waste liquid pool from getting into the pollution that instrument and equipment causes instrument and equipment.
Description of drawings
Fig. 1 shows the structural representation of basis for the anti-suck device of an embodiment of the utility model;
Fig. 2 shows the structural representation of basis for the anti-suck device of another embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified, but the embodiment of the utility model is not limited thereto.
Fig. 1 shows the structural representation of basis for the anti-suck device of an embodiment of the utility model.Anti-suck device as shown in Figure 1 comprises tank body 101 and cover 102; Cover 102 is arranged on the oral area of tank body 101; Cover 102 is tightly connected with tank body 101, and the below of cover 102 is provided with liquid seal device, and cover 102 is provided with blow vent 105; Liquid seal device comprises liquid storage container 103 and tube connector 106; Liquid storage container 103 is suspended on the below of cover 102, and an end of tube connector 106 stretches in the liquid storage container 103, the other end of tube connector 106 passes cover 102 and is communicated with the equipment that needs discharge opeing, and the bottom of tank body 101 is provided with leakage fluid dram 104.
During discharge opeing, waste liquid at first is full of the liquid storage container in the liquid seal device 103, is submerged in the drain side of tube connector 106 and is in the fluid-tight state in the liquid storage container 103, and excess liquid flows in the tank body 101 again, discharges from the leakage fluid dram 104 of tank body 101 bottoms.
Fig. 2 shows the structural representation of basis for the anti-suck device of another embodiment of the utility model.Tank body 201 shown in Fig. 2, cover 202, liquid storage container 203, leakage fluid dram 204 and blow vent 205 and the tank body 101 shown in Fig. 1, cover 102, liquid storage container 103, leakage fluid dram 104 and blow vent 105 structures, position, function are all identical, repeat no more at this.Tube connector as shown in Figure 2 has two, is respectively first tube connector 207 and second tube connector 208, can need the equipment of discharge opeing to be connected with two.
