Abstract

The utility model discloses a water-wetting dust filtering respirator. The main case body of the respirator comprises an upper case body and a lower case body. A respirator is disposed on the cover plate of the upper case body. A suction inlet is disposed on the outer wall. An air inlet is disposed between the upper and the lower case bodies. A spacer is disposed in the lower case body for dividing the lower case body into a turbid air chamber and a clear air chamber which are communicated at the lower end of the spacer. The air inlet connected with an air inlet pipe is disposed on the outer wall of the upper end of the turbid air chamber. Sponge net filtering material maintained in the water-wetting state is disposed at the lower end of the turbid air chamber and the lower end of the clear air chamber. The respirator can effectively filter out fine particles in air dust to ensure health of working personnel. The respirator, at the same time, has simple structure, which is convenient for replacing the sponge net filtering material or cleaning the case body.

Description

Water wet dust filter ventilator

Technical field

The utility model relates to a kind of water wet dust filter ventilator.

Background technology

During modern industry is produced, the waste gas of discharging as polishing, polishing, flour and machine etc., the smoke contamination of air is very serious, and the operating personnel sucks a large amount of contaminate particulates every day in production operation, is harmful to health.Though the workman can put on filtration utensils such as mouth mask during work, but because filtration utensil of the prior art is drying type, can only intercept thicker dust granules, depend on the trickle particle on surface, still can under the effect of suction, enter human body, cause multiple occupational disease.

The utility model content

The purpose of this utility model is to overcome above-mentioned defective, provides a kind of and can filter the water wet dust filter ventilator that adheres to fine solid particle.

In order to achieve the above object, the utility model comprises main box, is arranged on air inlet, gas outlet, respiratory siphon on the main box outer wall, and is arranged on the sponge net filtration thing in the casing; Main box is divided into upper box and lower box; Offer air entry between the last lower box, both are connected; Lower box inside is provided with space bar, and lower box is divided into muddy air chamber and clear air chamber; Clear air chamber and muddy air chamber are connected in the lower end of space bar; Sponge net filtration thing is the water wet condition, and is arranged on the lower end of air chamber and muddy air chamber clearly.

Of the present utility model going up between the lower box flexibly connects by the padlock groove, and its inner air entry is provided with air-breathing door; Air-breathing door is arranged on upper box one side; The gas outlet is arranged on the outer wall of upper box, and it is provided with air outlet valve.

Air inlet of the present utility model is arranged on the outer wall of muddy air chamber upper end, can an external air inlet pipe.

Owing to adopted such scheme, the utility model can filter out the fine particle in the air-borne dust effectively by the adhesive attraction of moisture to dust, and the guarantee operating personnel's is healthy.The utility model is simple in structure simultaneously, and it is all very convenient to change sponge net filtration thing or clean box body.

Description of drawings

Fig. 1 is the structure chart of a kind of embodiment of the utility model;

Fig. 2 is the structure chart of the another kind of embodiment of the utility model.

The specific embodiment

As depicted in figs. 1 and 2, padlock groove 13 is divided into upper box 1 and lower box 2 two parts of flexible connection to main box 18, is connected by air entry 6 between the two.On air entry, upper box one side, be provided with air-breathing door 17, make gas only entering upper box, and can not drive in the wrong direction from lower box.Gas outlet 5 is arranged on the sidewall of upper box, and its arranged outside has air outlet valve 15, gas is moved in upper box only outward, and can not enter in the casing.

There is a space bar 9 inside of lower box 2, and lower box is divided into muddy air chamber 10 and clear air chamber 11 two parts.Space bar 9 is extended to about the last 3cm in bottom from top to bottom by the top of lower box, and muddy air chamber and clear air chamber are connected in the lower end of space bar.The upper end of muddy air chamber and clear air chamber is a cavity, and the lower end is placed with sponge net filtration thing 19, and injects clear water, makes the sponge net keep the water wet condition.Offer air inlet 8 on the outer wall at cavity place, muddy air chamber upper end, air enters box house from this mouth.The all right external air inlet pipe 20 in air inlet place extends to air ratio place preferably with its other end during use, and inhaled air is comparatively cleaned, and more helps filtering and purifying, and reduces the replacing of filtrate and the cleaning time of casing.

As shown in Figure 1, the cover plate 3 of upper box is provided with one or two respiratory siphon 4, and it can add grows to Len req, and the upper end is fixing by geometrical clamp 21, and two ends are connected with a fixed band 22 respectively.Two respiratory siphons and human body nostril are complementary, and during use respiratory siphon are directly inserted in the nostril, fixed band is enclosed within on the ear, and by the cover of one on the lower box outer wall or two cover links and hook 7, casing is hung on the human body.As shown in Figure 2, the cover plate 3 of upper box is provided with a respiratory siphon 4, is connected with external respiratory siphon 16, and the other end of external respiratory siphon 16 is connected with external respirator 14, and external respirator can insert in the nostril of human body.The length of external respiratory siphon can be decided as required, and main box can be separated with the people during use, by link and hook 7, hangs over any position on every side, carries out various operations to make things convenient for personnel.

The course of work of the present utility model:

When air-breathing, after air entered muddy air chamber by air inlet pipe and air inlet, through the once filtration of water wet sponge screen pack, the filtration second time was carried out in the bottom of arrival interval plate, and entering clearly then, air chamber filters for the third time; Cleaned air passes enters in the cavity of the upper end of air chamber clearly, this moment air outlet valve close, air-breathing door opens, air enters in the upper box by air entry, enters human body by respiratory siphon then.During expiration, air is entered in the upper box by respiratory siphon by human body, and at this moment air-breathing door is closed, air outlet valve is opened, and air is discharged to the casing outside by the gas outlet.Circulation so repeatedly.
