Abstract
For a kind of crystal trapping device of anhydrides, relate to the collection device of the production technical field of pyromellitic acid anhydride and other anhydrides, particularly its crystal.Including cylindrical housings, being tightly connected spherical upper cover in the upper end of described housing, lower end is tightly connected taper low head, it is characterised 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 present invention can freely swing, in housing in addition to can strengthening heat exchange area, it is also possible to makes the material being attached on spring come off at any time, is not susceptible to materials from bonding thereon.The present invention has and has the advantage that: energy consumption is low, is lost little, and material yield is high, does not results in feed blocking, continuous operation, and labor intensity is low, it is not necessary to washing cleaning, does not produce waste water.
Description
Technical field
The present invention relates to the collection device of the production technical field of pyromellitic acid anhydride or other anhydrides, particularly its crystal.
Background technology
The crystal collection device of existing pyromellitic acid anhydride is provided with cylindrical housings, it is tightly connected spherical upper cover in the upper end of housing, 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 big, collects not thorough, and equipment is easily by feed blocking, it is difficult to cleaning, and washing can cause large amount of sewage, and environmental protection pressure is big, increases sewage disposal expense, and labor intensity is big.
Summary of the invention
Present invention aim at designing a kind of low energy consumption, be not susceptible to a kind of crystal trapping device for anhydrides of blocking.
The present invention includes cylindrical housings, being tightly connected spherical upper cover in the upper end of described housing, lower end is tightly connected taper low head, it is characterised 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 present invention can freely swing, in housing in addition to can strengthening heat exchange area, it is also possible to makes the material being attached on spring come off at any time, is not susceptible to materials from bonding thereon.The present invention has and has the advantage that: energy consumption is low, is lost little, and material yield is high, does not results in feed blocking, continuous operation, and labor intensity is low, it is not necessary to washing cleaning, does not produce waste water.
The installation of spring for convenience, in housing, netted link is fixed in upper surface, and the upper end of described each spring is connected on netted link.
It addition, the present invention also connects nitrogen access port at the sidewall of described housing.By periodically internally purging nitrogen, can further improve the antistick characteristic within spring, enclosure interior, upper and lower end socket.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As it is shown in figure 1, the present invention is provided with a cylindrical housings 1, being tightly connected spherical upper cover 2 in the upper end of housing 1, 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.Sidewall at housing 1 connects at least one nitrogen access port 4.
Upper surface in housing 1 is welded and fixed netted link 5, uniformly hangs some springs 6 in the housing 1 below this link 5, and 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 (1)
