Abstract

The utility model relates to a pelleter belonging to the field of benzene anhydrides chemical engineering, which is characterized in that the inner circumference of the pelleter roller is provided with an interlayer formed by a spiral channel. The structure resolves the problem that the prior pelleter roller cools down unsatisfactorily and the benzene anhydrides refrigerates on the surface of the roller which can hardly reach the technological requirements, thereby affecting the pelleter quality. Besides, as the weight of the roller can be greatly lightened by adopting the structure, thereby the consumption of power and the abrasion of relevant details can be remarkably reduced.

Description

A kind of flaker

A kind of flaker belongs to phthalic anhydride chemical industry equipment field.

Flaker in the existing phthalic anhydride chemical industry equipment, generally be by support, cylinder on the support and scraper are formed, its major function is with the cylinder surface continuously cooling and freezing of high-temperature liquid state phthalic anhydride at flaker, thereby the scraper of flaker scrapes the phthalic anhydride that solidifies on the cylinder continuously and obtains flaky solid-state phthalic anhydride product.For making the high-temperature liquid state phthalic anhydride can become uniform sheet structure in the cooled and solidified of cylinder surface continous-stable, the uniform and stable maintenance lesser temps of whole cylinder is most important, the cylinder of existing flaker generally is to be formed by single-layer metal coiled sheet system, its type of cooling generally is the end injection cold water from cylinder, hot water just flowed out from the other end of cylinder after water after treating to absorb heat in the cylinder covered cylinder axis, this type of cooling is because follow-up cold water one enters behind the cylinder promptly with hot water in the cylinder mixes, the effusive water of the other end of cylinder is the mixing water of hot water and cold water all the time, cold water does not fully absorb heat just with outflow of hot water, therefore its effect that cools is undesirable, thereby influenced the knot tablet quality of flaker, in addition because the whole in the course of the work cylinder of flaker inside all has been full of water, the volume of cylinder self is bigger again, thereby the water that is full of increased the weight of cylinder widely, also just increased the wearing and tearing of power consumption and relevant component simultaneously.

It is effective that the purpose of this utility model is to provide a kind of cylinder to cool, and scraper is more stable to the pressure of cylinder, can effectively improve the flaker of phthalic anhydride knot tablet quality.

The purpose of this utility model realizes as follows.

A kind of flaker, comprise support, rack-mount scraper and cylinder, and water-in on the cylinder two end axles and water outlet, it is characterized in that being provided with the interlayer that forms by spirality channel along said cylinder inner periphery, one end of spirality channel is communicated with water-in on the cylinder one end axle, and the other end is communicated with water outlet on the cylinder the other end axle.

The utility model flaker, its feature are that also an end of cylinder is provided with a lever on support, and said scraper is connected with an end of lever, and the fulcrum of lever is located on the support, and the other end of lever hangs balancing weight.

Owing to be provided with the interlayer that spirality channel forms in the cylinder of this flaker garden week, one end begins cylinder surface cooling continuously fast cold water from the feed-water end inflow interlayer of water channel and along spirality channel from cylinder under the pressure of recycle pump, when flowing to cylinder the other end cold water when water outlet is discharged, water fully absorbs heat, it is the highest that water temperature reaches, this type of cooling has made full use of the heat absorption capacity of cold water, it is cooled reach best effect, can improve the knot tablet quality of flaker preferably, simultaneously because the interior no unnecessary water of cylinder, can alleviate cylinder weight greatly, effectively reduce power consumption and relevant parts wear, because the improvement of flaker structure, its function is reduced greatly, only just can normally drive, reduce by 12 kilowatts than existing flaker with 4 kilowatt motors.

Below in conjunction with accompanying drawing the utility model flaker is described further.

Fig. 1 is the flaker structure iron.

Fig. 2 is a flaker cylinder axial section.

The cylinder 4 of flaker is installed between two bearing supports 3 on the support 1, be installed in the parallel contact of outer garden element cylinder of blade with the cylinder 4 of the scraper 5 on the support 1, axis hole one end at cylinder 4 two ends is prosopyles 7, the other end is a posticum 12, be provided with the interlayer 11 that spirality channel forms the interior garden week of cylinder 4, be respectively equipped with seal diaphragm 9 between week near the axle at cylinder two ends and the interior garden of interlayer 11 in the cylinder 4, axle between the interlayer 14 that seal diaphragm 9 and cylinder end form be provided with axle on water-in 7 and the flowing water mouth 8 that connects of water outlet 12, be provided with the flowing water mouth 10 that connects with spirality channel the interior garden week between the cylinder two ends interlayer 14, the bottom of cylinder 4 outside surfaces is positioned at and holds liquid phthalic anhydride pond 2.

In the above-described embodiments, can also remove dividing plate 9, flowing water mouth 8 and flowing water mouth 10 directly are communicated with pipe.

When flaker is worked, cylinder 4 rotates under the drive of motor, the garden perimeter surface of cylinder 4 turns over phthalic anhydride pond 2 continuously, high-temperature liquid state phthalic anhydride in the phthalic anhydride pond 2 is in the outside surface cooled and solidified of cylinder 4, the phthalic anhydride of cooled and solidified rotates with the outside surface of cylinder, when the phthalic anhydride that solidifies goes to scraper 5 places, scraped and fall into solid-state phthalic anhydride collection device and obtain solid-state phthalic anhydride product by scraper 5, meanwhile, water coolant is under the pressure of water circulating pump, enter spirality channel from water-in 7 past flowing water mouths 8 and flowing water mouth 10, and along the continuous cooling in the surface of 11 pairs of cylinders 4 of spirality channel interlayer, when water when spirality channel flow to the other end of interlayer 11, the whole garden perimeter surface of cylinder 4 is all cooled off, fully the water after the heat absorption cools again from the recycle system that water outlet 12 outflows enter the outside again, and circulation so continuously just can make the maintenance low-temperature condition of the surperficial continous-stable of cylinder 4.

Claims

1, a kind of flaker, comprise support, rack-mount scraper and cylinder, and water-in on the cylinder two end axles and water outlet, it is characterized in that along being provided with the interlayer that spirality channel forms garden week in the cylinder, one end of spirality channel is communicated with water-in on the cylinder one end axle, and the other end is communicated with water outlet on the cylinder the other end axle.
