Abstract
The utility model relates to an alkali boiling device for cleaning a spinneret plate. The alkali boiling device comprises a cylindrical cylinder wall, a tapered cylinder bottom and a metal mesh sieve; the alkali boiling device is characterized in that the tapered cylinder bottom is connected with the cylindrical cylinder wall; a layer of metal mesh sieve is arranged at junction of a tapered bottom and a cylinder; the tapered cylinder bottom is provided with a stirring paddle; an included angle of generatrix of the tapered cylinder bottom and the horizontal plane is 25-50 degrees; the metal mesh sieve is made of a stainless steel material, and has the mesh number of 4-150 meshes. According to the alkali boiling device for cleaning the spinneret plate disclosed by the utility model, impurities collected by a rotary nest can be effectively prevented from rolling over to the periphery of the spinneret plate again due to stirring and boiling of alkali liquor in the presence of the metal mesh sieve.
Description
[technical field]
The utility model relates to spinnerets cleaning technique field, relates to specifically a kind of soda boiling device that cleans spinnerets.
[background technology]
In modern man-made fibres industry produces, spinnerets is precision components important in spinning moulding process, is the strength member that is related to fiber quality and produces normal operation.Hole diameter in spinnerets and length are the key parameters of spinnerets, the problems such as direct relation strand quality and production normal operation.And in spinning process, owing to existing in high polymer molten or solution, mix or functional additive etc., often can cause the obstruction of spinneret orifice and affect normal spinning.Therefore the cleaning for spinnerets is to guarantee normal important step of producing.
The cleaning method of correct appropriate spinnerets is very important, cleaning method has salt bath method, fluidized bed type oven process etc., wherein modal flow process is: calcining → soda boiling → Ultrasonic Cleaning → microscopy, in alkali cooking process, normally alkaline cleaner, water or other solvents are added in flat cylindrical stainless steel heating cylinder, and the spinnerets after calcining is fixed on and on rack for cleaning, puts into soda boiling cylinder agitating heating a few hours.Due to the finite volume of soda boiling cylinder, the spinnerets after simultaneously calcining has a lot of impurity and comes off and enter into alkali lye from spinnerets in the process that stirs soda boiling.A large amount of impurity can flow and seethe with excitement because of stirring, thermal convection current and move back and forth in spinnerets and spinnerets in limited soda boiling cylinder body is long-pending, make an impurity being washed away stick to again on spinnerets, can not allow impurity and spinnerets well separate, cause cleaning efficiency low, the after backwashing rate of spinnerets is high.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of soda boiling device that cleans spinnerets is provided, the soda boiling device that uses the utility model to clean spinnerets can wash out residual impurity in the spinnerets after calcining and be fast that impurity is separated with spinnerets, effectively prevent that the impurity washing out from continuing, in spinnerets rolling around, greatly to have promoted the cleaning efficiency of soda boiling cylinder to spinnerets.
The purpose of this utility model is achieved through the following technical solutions:
A soda boiling device for spinnerets, it comprises cylindric casing wall, and coniform cylinder bottom and wire-mesh screen, is characterized in that, and coniform cylinder bottom is connected with cylindric casing wall, in conical lower portion and cylinder connection place, layer of metal mesh screen is set.
Described taper cylinder bottom arranges stirring arm.
The bus of described circular cone cylinder bottom and the angle of horizontal plane are 25 °～50 °
Described wire-mesh screen is stainless steel, and order number is 4～150 orders.
Compared with prior art, advantage of the present utility model:
Described soda boiling device has coniform cylinder bottom, coniform cylinder bottom is connected with cylindric casing wall, the flat-bottom structure that is different from conventional soda boiling device, when coniform cylinder bottom arranges stirring arm, the bottom of taper contributes to form revolves nest, the bottom that impurity is collected device fast due to the effect meeting of gravity, can effectively avoid because alkali lye stirs with boiling, causing impurity to roll back and forth in flat cylinder.
Described soda boiling device installs layer of metal mesh screen additional in conical lower portion and cylinder connection place, and the existence of wire-mesh screen can effectively stop by revolving impurity that nest collects and again rolls to around spinnerets because alkali lye stirs with boiling.
[accompanying drawing explanation]
A kind of soda boiling apparatus structure schematic diagram that cleans spinnerets of Fig. 1 the utility model
Being labeled as in accompanying drawing: 1 cylindric casing wall, 2 wire-mesh screens, 3 coniform cylinder bottoms, 4 paddles
[specific embodiment]
Below provide the utility model a kind of specific embodiment of cleaning the soda boiling device of spinnerets.
Refer to accompanying drawing 1, a kind of soda boiling device that cleans spinnerets, it comprises cylindric casing wall 1, coniform cylinder bottom 3 and wire-mesh screen 2, it is characterized in that, coniform cylinder bottom is connected with cylindric casing wall, in conical lower portion and cylinder connection place, layer of metal mesh screen is set.
Described taper cylinder bottom arranges stirring arm 4.
A kind of soda boiling device that cleans spinnerets of the present utility model, by material, be that stainless coniform cylinder bottom connects by argon tungsten-arc welding mode with the cylindric casing wall of identical material, cylinder block diameter is 120cm, circular cone cylinder bottom bus is horizontal by 40° angle, at cylinder interior, cylindric casing wall and coniform cylinder bottom link position place fixedly order number are the 10 stainless steel mesh screens that mate with cylinder interior, adopt conventional soda boiling technique to carry out soda boiling to spinnerets.In the detection of later process, the after backwashing rate of spinnerets is 0.1%, and cleaning performance is compared obvious raising with conventional soda boiling device.
Claims (4)
