Abstract
The utility model discloses a vacuum pumping device for weighing a modifying agent. The vacuum pumping device comprises a vacuum pump, an upper box body and a water tank connected to the lower part of the upper box body, wherein a sprinkler is arranged at the area at the upper part in the upper box body; the water tank is connected with the sprinkler by a water pipe; a sponge piece is arranged between the sprinkler and a pumping pipe; the center of the sponge piece is provided with two horn-shaped holes, and openings of the two horn-shaped holes are gradually reduced towards the direction of the pumping pipe. The vacuum pumping device has the beneficial effects that in the running process, the modifying agent passes through the upper box body and the water tank; the sprinkler is arranged at the area at the upper part in the upper box body, a water curtain is formed by the water sprayed by the sprinkler, and the modifying agent is easily absorbed by the water curtain when passing through the water curtain after entering the upper box body from a suction tube; the sponge piece is also arranged between the top wall of the upper box body and the bottom surface of the water tank in a spacing way, so that the content of the modifying agent is effectively reduced. The modifying agent is cleaned in the upper box body and the water tank, and most modifying agents are absorbed and dissolved by the water, so that the influence on the vacuum pump is effectively reduced.
Description
Technical field
The utility model relates to a kind of vacuum extractor, especially a kind of vacuum extractor weighing for modifier.
Background technology
Chinlon 6 section is the primary raw material of producing nylon-6 fiber, and in the production process of chinlon 6 section, benzylamine uses as modifier, and this just need to weigh to benzylamine in process of production.The benzylamine weighing-appliance of existing chinlon 6 section production use comprises benzylamine head tank, gravimetric tank and vavuum pump, benzylamine head tank is connected with gravimetric tank by pipeline, gravimetric tank is connected with vavuum pump by pipeline, while weighing, vavuum pump work makes to produce negative pressure in gravimetric tank, and the benzylamine in benzylamine head tank is just drawn in gravimetric tank and realizes and weighing like this.Because benzylamine exists volatile feature, the benzylamine gas existing in benzylamine head tank is finally discharged from vavuum pump, therefore there are following two technical problems in this benzylamine weighing-appliance: 1, benzylamine gas has corrosivity, after entering vavuum pump, can cause vavuum pump pad aging, affect the service life of vavuum pump; 2, benzylamine gas is finally discharged from vavuum pump, easily contaminated environment.Other modifier of similar chemical fibre industry is being deposited the problems referred to above equally.Because gas modifier (as benzylamine) is mostly solvable, therefore water absorb soluble modified dose be the effective means of removing the gas modifier containing in waste gas.
Owing to there is above-mentioned technical problem, be therefore necessary existing modifier weighing-appliance to improve.
Summary of the invention
The purpose of this utility model is the deficiency in order to solve above-mentioned technology and a kind ofly guaranteeing service life of vacuum pump, preventing a kind of Novel evacuating device weighing for modifier of contaminated environment of designing.
The vacuum extractor weighing for modifier that the utility model is designed, comprise vavuum pump, upper box and be connected to the water tank of upper box bottom, described vavuum pump is positioned at upper box top, described upper box one side is provided with suction line, opposite side is provided with and extracts pipe out, the region of described upper box internal upper part is provided with spray equipment, spray equipment is near suction line one side, and described water tank is connected with described spray equipment by water pipe, is provided with water pump on water pipe; Between described spray equipment and extraction pipe, be provided with sponge block, described sponge block is limited between upper box roof and water tank bottom surface, and is provided with two openings in the center of sponge block to extracting the diminishing flared hole of pipe direction out; The entrance of described extraction pipe is positioned at described flared hole top, and described extraction pipe connects described vavuum pump, below extraction pipe, is also provided with a water pot.
The vacuum extractor weighing for modifier that the utility model is designed, its beneficial effect is: when vavuum pump work, upper box is pumped into negative pressure, gas modifier enters in upper box by suction line, upper box is connected to water tank upper, and water tank is connected with described spray equipment by water pipe, compared with prior art, gas modifier has passed through upper box and water tank in running, the region of upper box internal upper part is provided with spray equipment, spray equipment is near suction line one side, spray equipment ejection water forms spray band together, gas modifier is easily with solution absorption by spray through spray band after entering upper box by suction line, between upper box roof and water tank bottom surface, be also interval with sponge block simultaneously, sponge block is under water is very moist, the gas modifier not absorbed by shower water can be dissolved in the contained water of sponge block, can effectively reduce like this content of gas modifier, sponge block can prevent that shower water from being extracted out by vavuum pump in addition.Overwhelming majority gas modifier is absorbed and dissolves by water, so just can effectively reduce the impact on vavuum pump, guarantees its service life, can reduce in addition modifier discharge capacity, and effectively protection of the environment prevents from polluting.

Fig. 1 is the structural representation of embodiment 1;
In figure: vavuum pump 1, upper box 2, water tank 3, suction line 4, extraction pipe 5, spray equipment 6, water pipe 7, water pump 8, sponge block 9, flared hole 10, water pot 11.
Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, the described vacuum extractor weighing for modifier of the present embodiment, comprise vavuum pump 1, upper box 2 and be connected to the water tank 3 of upper box 2 bottoms, described vavuum pump 1 is positioned at upper box 2 tops, described upper box 2 one sides are provided with suction line 4, opposite side is provided with and extracts pipe 5 out, and the region of described upper box 2 internal upper parts is provided with spray equipment 6, and spray equipment 6 is near suction line 4 one sides, described water tank 3 is connected with described spray equipment 6 by water pipe 7, is provided with water pump 8 on water pipe 7; Between described spray equipment 6 and extraction pipe 5, be provided with sponge block 9, described sponge block 9 is limited between upper box 2 roofs and water tank 3 bottom surfaces, and is provided with two openings in the center of sponge block 9 to extracting the diminishing flared hole 10 of pipe 5 direction out; The entrance of described extraction pipe 5 is positioned at described flared hole 10 tops, and described extraction pipe 5 connects described vavuum pump 1, below extraction pipe 5, is also provided with a water pot 11.
The described vacuum extractor weighing for modifier of the present embodiment, when vavuum pump 1 is worked, upper box 2 is pumped into negative pressure, modifier enters in upper box 2 by suction line 4, and upper box 2 is connected to water tank 3 tops, and water tank 3 is connected with described spray equipment 6 by water pipe 7; When spraying water, spray equipment 6 forms spray band together, in the process that gas modifier is flowed into upper box 2 by suction line 4, easily absorbed by spray band through spray band, between upper box 2 roofs and water tank 3 bottom surfaces, be also interval with sponge block 9 simultaneously, sponge block 9 is immersed in water tank 3 and keeps moisture state, the gas modifier not absorbed by shower water can be dissolved in the contained water of sponge block 9, can effectively reduce like this content of modifier.Gas modifier is cleaned in sprayed tank, and most gas modifier is absorbed and dissolves by water, so just can effectively reduce the impact on vavuum pump, guarantees its service life, can reduce in addition gas modifier discharge capacity, and effectively protection of the environment prevents from polluting.
