Abstract
For a kind of crystal trapping device of anhydrides, relate to the gathering-device of the production technical field of pyromellitic acid anhydride and other anhydrides, particularly its crystal.Comprise cylindrical housings, be tightly connected in the upper end of described housing spherical upper cover, and lower end is tightly connected taper low head, it is characterized in that uniform some springs in housing, the upper end of each spring is connected to the upper end of housing, and the lower end of each spring is respectively free end.The spring arranged due to the utility model can freely swing in housing, except strengthening except heat exchange area, the material be attached on spring can also be made to come off at any time, not easily materials from bonding occurs thereon.The utility model has has advantage to be: energy consumption is low, and loss is little, and material yield is high, and can not cause feed blocking, continued operation, labour intensity is low, without the need to washing cleaning, does not produce waste water.
Description
Technical field
The utility model relates to the gathering-device of the production technical field of pyromellitic acid anhydride or other anhydrides, particularly its crystal.
Background technology
The crystal gathering-device of existing pyromellitic acid anhydride is provided with cylindrical housings, be tightly connected in the upper end of housing spherical upper cover, lower end is tightly connected taper low head, in housing outer clip shell type, circulating water cooling system is set, at the fixing deflection plate of enclosure interior design, high temperature crystallization body enters from upper cover and ejects from the bottom of low head after cooling.
The shortcoming of this device is: energy consumption is high, and loss is large, and collect not thorough, equipment is easily by feed blocking, and be difficult to cleaning, washing can cause large amount of sewage, and environmental protection pressure is large, and increase sewage disposal expense, labour intensity is large.
Utility model content
A kind of crystal trapping device for anhydrides that the utility model object is to design a kind of low energy consumption, blocking not easily occurs.
The utility model comprises cylindrical housings, be tightly connected in the upper end of described housing spherical upper cover, and lower end is tightly connected taper low head, it is characterized in that uniform some springs in housing, the upper end of each spring is connected to the upper end of housing, and the lower end of each spring is respectively free end.
Described its length is identical with shell length.
The spring arranged due to the utility model can freely swing in housing, except strengthening except heat exchange area, the material be attached on spring can also be made to come off at any time, not easily materials from bonding occurs thereon.The utility model has has advantage to be: energy consumption is low, and loss is little, and material yield is high, and can not cause feed blocking, continued operation, labour intensity is low, without the need to washing cleaning, does not produce waste water.
The conveniently installation of spring, in housing, netted link is fixed in upper surface, and the upper end of described each spring is connected on netted link.
In addition, the utility model also connects nitrogen access port at the sidewall of described housing.By regularly internally purging nitrogen, can further improve the antistick characteristic of spring, enclosure interior, upper and lower end socket inside.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model is provided with a cylindrical housings 1, and be tightly connected in the upper end of housing 1 spherical upper cover 2, and lower end is tightly connected taper low head 3, and upper cover 2 is provided with treatment fluid access port, and low head 3 lower end is provided with out brilliant mouth.At least one nitrogen access port 4 is connected at the sidewall of housing 1.
Upper surface in housing 1 is welded and fixed netted link 5, and evenly hang some springs 6 in the housing 1 below this link 5, the length of each spring 6 of hanging is identical with the length of housing 1, and the lower end of each spring 6 is respectively swingable free end.
Claims (4)
