The lower part of the side face of the second filter is provided with a second air inlet pipe, on which a second air inlet valve is arranged; and the upper part of the second filter is provided with a second air outlet pipe and a second blowback air pipe, the second air outlet pipe is provided with a second air outlet valve and the second blowback air pipe is provided with a second blowback valve. The melamine gas filtering device has the advantages as follows: double filters are arranged, so that one filter can work normally, the other filter conducts blowback, continuous air filtration is guaranteed and the production efficiency is high; and coordinated control among all valves prevents the filter from having excessive pressure and guarantees safe production, and the like.

Description

A kind of melamine gas-filtering device
Technical field
The utility model relates to Melamine Production device field, specifically is a kind of melamine gas-filtering device.
Background technology
In the preparation technology of melamine, generate impurity in the gas, generation gas need be transported in the melamine pneumatic filter and filter in order to remove.But existing filter in use, usually can influence filter efficiency because of impurity is more, and need carry out the blowback dedusting this moment to filter.In existing apparatus, when filter is carried out the blowback dedusting, often need process units is shut down, carry out blowback then, this can influence carrying out continuously of production, reduces Melamine Production efficient.
Summary of the invention
The purpose of this utility model is to provide a kind of melamine gas-filtering device, and it can solve the deficiency that exists in the known technology, by twinfilter and relevant device are set, can realize generating gas continuous filtration, enhances productivity.
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of melamine gas-filtering device, comprise first filter and second filter, first air inlet pipe is installed in bottom, the first filter side, first air inlet pipe is communicated with the inlet manifold, first air intake valve is installed on first air inlet pipe, first escape pipe and the first blowback tracheae are installed in the first filter top, first escape pipe is communicated with gas transmission main, first valve of giving vent to anger is installed on first escape pipe, the first blowback tracheae communicates with source of the gas, the first blowback valve is installed on the first blowback tracheae, and second air inlet pipe is installed in bottom, the second filter side, and second air inlet pipe is communicated with the inlet manifold, second air intake valve is installed on second air inlet pipe, second escape pipe and the second blowback tracheae are installed in the second filter top, and second escape pipe is communicated with gas transmission main, and second valve of giving vent to anger is installed on second escape pipe, the second blowback tracheae communicates with source of the gas, and the second blowback valve is installed on the second blowback tracheae.
Described source of the gas is an air pump, and the first blowback tracheae and the second blowback tracheae are communicated with air pump respectively.
First air intake valve, first is given vent to anger and is connected by lead between valve and the first blowback valve, and second air intake valve, second is given vent to anger and is connected by lead between valve and the second blowback valve.
Advantage of the present utility model is: twinfilter is set, can realizes a filter operate as normal, another filter carries out blowback, and what guarantee gas filtration carries out the production efficiency height continuously; Simple for structure reasonable, be easy to control; Chain control between each valve, when air intake valve was closed simultaneously with the valve of giving vent to anger, the blowback valve guaranteed closed condition, prevents the filter superpressure, guarantees safety in production etc.
Description of drawings
Accompanying drawing 1 is a main TV structure schematic diagram of the present utility model.
The specific embodiment
The utility model is described in further detail for the contrast accompanying drawing:
Agent structure of the present utility model comprises first filter 6 and second filter 17, be provided with gas-filtering device in first filter 6 and second filter 17, in bottom, first filter, 6 side first air inlet pipe 4 is installed, first air inlet pipe 4 is communicated with inlet manifold 3, first air intake valve 5 is installed on first air inlet pipe 4, first escape pipe 7 and the first blowback tracheae 9 are installed in first filter, 6 tops, first escape pipe 7 is communicated with gas transmission main 11, first valve 8 of giving vent to anger is installed on first escape pipe 7, the first blowback tracheae 9 communicates with source of the gas, the first blowback valve 10 is installed on the first blowback tracheae 9, second air inlet pipe 2 is installed in bottom, second filter, 17 side, second air inlet pipe 2 is communicated with inlet manifold 3, second air intake valve 1 is installed on second air inlet pipe 2, second escape pipe 15 and the second blowback tracheae 14 are installed in second filter, 17 tops, second escape pipe 15 is communicated with gas transmission main 11, second valve 16 of giving vent to anger is installed on second escape pipe 15, the second blowback tracheae 14 communicates with source of the gas, and the second blowback valve 13 is installed on the second blowback tracheae 14.
Described source of the gas can be various sources of the gas, for example the blowback tracheae is connected with different air pump respectively, an air pump 12, the first blowback tracheaes 9 and the second blowback tracheae 14 preferably are set are communicated with air pump 12 respectively, single air pump 12 is set, can reduces the utility model manufacturing cost.
In the foregoing description, first air intake valve 5, first valve 8 of giving vent to anger is connected by lead with 10 on the first blowback valve, second air intake valve 1, second valve 16 of giving vent to anger is connected by lead with 13 on the second blowback valve.In the present embodiment, corresponding air intake valve, give vent to anger and realize chain control between valve and blowback valve, when air intake valve and the valve of giving vent to anger are closed simultaneously, can guarantee that the blowback valve is in closed condition, prevent the filter superpressure, guarantee that production safety carries out.
When the utility model uses, at first close second air intake valve 1, second valve 16 of giving vent to anger, the first blowback valve 10 and the second blowback valve 13, open first air intake valve 5 and first valve 7 of giving vent to anger, gas enters first filter 6 and filters, after using a period of time, when needs are cleared up first filter 6, open first air intake valve 5, second air intake valve 1, second valve 16 of giving vent to anger, the first blowback valve 10, close the second blowback valve 13 and first valve 8 of giving vent to anger, 12 pairs first filters of air pump 6 carry out the blowback removal of impurities, and this moment, gas filtered by second filter 17.So repeatedly, realize gas continuous filtration, guarantee to produce operation continuously, enhance productivity.
