Description

Pre-crystallization device

Technical Field

The utility model belongs to the technical field of textile machinery, and relates to a pre-crystallization device.

Background

The current crystallization and drying process is a continuous pre-crystallization BM type drying equipment process, in the production of a machine, slices are pre-crystallized in a pre-crystallizer by a method of boiling and impacting each other, along with the increase of the number of times of beating and the increase of the pre-crystallization time, the slices collide and rub into a columnar ellipse, fall and gather in mesh holes, the mesh holes of a pre-crystallization mesh plate are inevitably blocked, the air outlet is uneven, the jumping height of the slices is reduced, and then the slices are blocked, namely, the slices do not jump after blocking the mesh holes, and can not normally boil in a pre-crystallization device and jump into a drying tower. The long-time putty can lead to the material level of the drying tower to be reduced so as to influence the product quality.

As shown in fig. 1, the plugging positions are generally three positions, namely a first position for pre-crystallization and a second position for pre-crystallization at the blanking rotary valve device 2, below the rotary valve device 2.

Wherein if the cut slice is blocked at the blanking rotary valve device, the rotary valve device must be stopped, and then the rotary valve device is disassembled for cleaning, and the blocking is generally caused by the operation failure of the rotary valve device, so that the blocking condition is less.

If the slice is blocked at the first and second positions of the crystallization, the crystallization system must be stopped, the crystallization fan is closed, the first manhole device 4 on the front surface and the second manhole device 5 on the side surface of the crystallizer are removed, the blocked position is sliced, and the blocked position of the crystallization mesh plate is cleaned. The reasons for the blockage are generally: the crystallization net holes are blocked by slices (the slices are jumped and boiled in the crystallization bed, and round net holes can be blocked by the slices which strike the fragments over the years), so that the crystallization air quantity is smaller, the slices are jumped slowly in the pre-crystallizer, and the jumping height is lower until the accumulation is blocked.

Because the cleaning work after material blockage is complex, the temperature is high, the time is long, and the labor is wasted; meanwhile, the longer the fan is stopped, the more the drying material level is lowered, the larger the dyeing deviation probability is, and the product quality is affected.

The current workshop treatment putty condition is: firstly, the plugging time is uncertain, and can be any time such as daytime, evening or early morning, and the like, secondly, after plugging, the user needs to go to a button for closing a pre-crystallization system as soon as possible, a crystallization fan button is closed, a manhole device on a crystallizer is removed, the temperature in the crystallization system is waited to be reduced, the plugged position is manually sliced and drawn out against the high temperature in the crystallizer, mesh holes blocked by crystal meshes are cleaned one by one, and the method is time-consuming and labor-consuming and difficult to decoct at high temperature.

The patent CN 216953772U changes the circular crystallization mesh into wide rectangular or diamond-shaped meshes, so that the probability of blocking the crystallization mesh plate by the slice is reduced, the time for blocking the mesh hole by the slice is prolonged to a certain extent, but the times of high-temperature material drawing and cleaning the crystallization mesh plate during normal material blocking cannot be reduced; patent CN 210590052U changes the direction of blowing of a crystallization fan into the direction of upward slant right, blows the slice directly into the drying tower, and the slant upward blowing can reduce the quantity that the slice falls in the same time, and then prolongs the time that the slice is blocked, but will directly blow the slice into the drying tower can be because of the influence of the product quality that the slice does not have the crystallization completely brought can be greater than the cost of high temperature clearance putty slice condition.

Therefore, the crystallization device is necessary to be improved, the slicing quantity can be monitored in real time, the blocking condition is automatically solved, normal production is maintained, the times of high-temperature material drawing and crystal mesh plate cleaning during normal blocking can be effectively reduced, the alarming times can be recorded, workers are reminded of cleaning the crystal mesh plate at regular time, the secondary blocking is avoided, the labor consumption is greatly reduced, the product quality is guaranteed, and the economic benefit is increased.

As a preferable technical scheme:

according to the pre-crystallization device, the blanking rotary valve device is connected with the feeding port of the pre-crystallization device, and the slices fall into the crystallization tower through the operation of the blanking rotary valve device.

The crystallization mesh plate is positioned above the drying tower and is communicated with the drying tower through the connecting pipeline II and the connecting pipeline I; the skip baffle is closely attached above the crystallization mesh plate.

According to the pre-crystallization device, the length of the long side of the crystallization mesh plate is 80-100 cm (depending on different flow rates of the crystallizer), the length of the crystallization mesh plate is prolonged by a certain length on the original basis (the prolonged length only needs to ensure that the mesh plate can smoothly put slices into the drying tower through the connecting pipeline above the drying tower when the mesh plate is inclined downwards, if the length of the mesh plate is not prolonged, the slices can fall into the crystallization secondary air pipe when the mesh plate is inclined downwards for discharging, the air output of the crystallization secondary pipeline can be reduced), the length of the short side is 20-30 cm, and the thickness is 0.5-1 cm.

In the pre-crystallization device, two long sides of the crystallization mesh plate are closely attached to the inner wall of the pre-crystallization device.

In the pre-crystallization device, crystallization meshes penetrating through the upper surface and the lower surface are uniformly distributed on the surface of the crystallization mesh plate, and the crystallization meshes are diamond-shaped; changing a round hole crystallization mesh plate into a diamond mesh plate, firstly ensuring that the crystallization air output is kept unchanged or the air output is increased under the crystallization mesh plate with the same area; and the diamond meshes can prolong the cleaning time of the blockage of the slice to a certain extent relative to the round meshes, the slice is inevitably collided and rubbed into a columnar ellipse with a high probability in the process of collision jump and landing, and the chance of blocking the round meshes is higher than that of the diamond meshes.

the load bearing sensing device 12.2 is composed of a mechanical controller 20, a total sensor module 21, a capacitance sensor 18, a load bearing sensor 16, a first position sensor 14, a second position sensor 15, a speed position sensor 17 and a power supply 19; the mechanical controller 20, the total sensor module 21, the capacitance sensor 18, the bearing sensor 16, the first position sensor 14, the second position sensor 15 and the speed position sensor 17 are arranged on the lower surface of the crystallization mesh plate, distributed on the periphery of the lower surfaces of the first crystallization area and the second crystallization area and not shielding crystallization meshes, and the sensors are connected through induction lines; a power supply 19 is fixed to the outer surface of the pre-crystallization apparatus.

The operation of the above-mentioned pre-crystallization apparatus is as follows:

the machine controller 20 is used for collecting process parameters and controlling the output of actions; the total sensor module 21 converts information collected and detected in each sensor in actual production into an electric signal or other forms of information according to a certain rule for transmission; the capacitive sensor 18 displays information related to the load bearing sensing device in an operation display screen, such as alarm information, process parameters, setting/modifying operation data, equipment switches, information storage, etc.; the first position sensor 14 controls the turning plate shaft 13 to rotate; the second position sensor 15 can drive the mesh plate to incline downwards or lift upwards; the speed position sensor 17 mainly drives the crystallization mesh plate to slide leftwards and downwards along the slide rail 10 in an arc shape by a sliding block or lift; the machine controller 20 monitors the slice amount in real time and records the number of alarms.

The slice boiling in the pre-crystallization device needs a certain bed height, so that a certain crystallization time and a crystallization boiling starting height are ensured, the total slice amount of the crystallization meshes of the optimal bed height is recorded as a (including slices boiling in mid-air), the upper limit of the total slice amount of the load-bearing device is 1.2a, and the lower limit of the total slice amount of the load-bearing device is 0.1a. If the total slice amount of the crystallization mesh plate is more than a, the speed of the slice jumping to the drying tower is slow, and under the condition that the process conditions are not changed, the mesh plate is possibly blocked, so that the air output of the first or second crystallization position is reduced, the total slice amount on the mesh plate is increased, and the upper limit is set to be 1.2a for preventing slice blocking. If the total slice quantity of the crystal mesh plate is less than a, the speed of the slice jumping to the drying tower is likely to be increased, the blanking speed of the rotary valve is also likely to be reduced, and under the condition that the process conditions are not changed, the blanking of the rotary valve is only abnormal, so that the total slice quantity on the mesh plate is reduced. Since if the mesh plate is blocked, the direct result is that the crystallization two-output air volume becomes small, the slice jump material becomes slow, and the total slice in the crystallization mesh plate can only be more than a, when the total slice amount of the crystallization mesh plate is less than a, the rotary valve is abnormal. When the rotary valve is abnormal, the blanking is reduced or not, the total slice amount in the crystallization mesh plate is slowly reduced to be close to 0, so that when the total slice amount is slowly reduced, a minimum value is set to prevent the material level of a drying tower from being reduced due to long-time blanking in the crystallization mesh plate and influence the product quality, and the lower limit is set to be 0.1a (in actual production, the total slice amount of the crystallization mesh plate can be produced within the range of [0, a ] and can be actually used as the lower limit value within the range of 0-1.0 a); when the total slice quantity at the crystallization mesh plate is 0.1a, the crystallization mesh plate bearing sensing device does not need to incline, and the rotary valve is closed by stopping the fan, so that the abnormality of the rotary valve is checked.

When the total slice quantity at the crystallization mesh plate is 1.2a and has a trend of increasing, the crystallization mesh plate bearing sensing device can slowly incline downwards to automatically put redundant slices from the crystallization mesh plate to the drying tower (the problem that more slices are put and less slices are put exists at the position, the error quantity is about 5%, and at the same time, micro slices fall into the crystallization air pipe at two sides when the mesh plate is slowly inclined to put materials, the micro slices are ignored), and when the redundant slices are about 0.2a and completely fallen into the drying tower, the crystallization mesh plate bearing sensing device can slowly return to the original position by itself to continue production; if the mesh plate is inclined, the slice clamped in the mesh can not be poured out, if the mesh plate is inclined, the situation that the bearing of the crystallization mesh plate is increased at the moment is indicated, which is an early warning signal (the alarm frequency is 1 time) before blocking, and under the condition that the process condition is not changed, the mesh plate is blocked, so that the slice clamped in the mesh can not be cleaned temporarily, and the fan can be stopped for cleaning when the blocking is completed.

In the mesh plate downward inclination process, when the slice can slowly fall into the drying tower through the drying tower upper pipe, the phenomenon that the quality of a product can be influenced finally because the adhesion condition can occur when redundant slice 0.2a is scattered into the drying tower and then the slice can be agglomerated in the drying tower and the running and the spinning stability of a screw rod can be influenced is also possible. First, the blocking condition can be considered to be mainly three conditions: firstly, slices which are just dropped from the rotary valve and are not pre-crystallized or have shorter pre-crystallization time are adhered to each other; secondly, the slice which falls down by the rotary valve and is not pre-crystallized or has shorter pre-crystallization time is adhered to the crystallized slice; thirdly, the crystallized slice is adhered to itself. When the above adhesion slice (the maximum value is 0.2 a) falls into the drying tower, compared with the prior art (the material level of the drying tower is reduced due to material blockage, a large amount of slices are generated due to material blockage cleaning by a fan, and the dyeing deviation degradation of the product is caused due to overlong drying time), the influence on the quality of the product is extremely small, the slice adhesion generated by discharging is extremely small relative to the total slice amount of the whole drying tower, and the scheme of the device for processing the material blockage is enough to compensate for the tiny difference caused by the slice adhesion on the waste of the slice, the drying time and the material level of the slice of the drying tower, so the influence caused by the adhesion slice is relatively negligible basically.

In a normal operation state, the slice automatically falls down to the upper surface of a crystal mesh plate through a blanking rotary valve device, crystallization one and crystallization two areas on the crystal mesh plate pre-crystallize the falling slice of the rotary valve, air sent out from a crystallization fan reaches the lower surface of the mesh plate through a crystallization one air channel and a crystallization two air channels, the slice piled on the mesh plate is blown up through meshes on the mesh plate, so that the slice is crystallized in a boiling state, one part of the slice stays on the upper surface of the mesh plate to be boiled, one part of the slice jumps above the mesh plate, one part of the slice passes over a jump plate to jump into a drying tower, and then the slice falls into the mesh plate along with the operation of the rotary valve device, so that a series of actions of falling, slice boiling, slice jumping and slice passing over the drying tower keep the normal operation of a crystallization drying system, the crystal mesh plate is in a horizontal state, and a slide block is in a fixed state at the upper end of a slide rail; the air sent out by the crystallization fan enters the crystallization fan at the air outlet of the pre-crystallization device to form circulation, the circulation air path is irrelevant to the utility model, and the details are not written out in detail, and the device diagram is not shown;

when the blockage occurs, if the blockage is caused by the blanking of the rotary valve device, the rotary valve device is maintained by stopping the fan; if the blocking caused by the material jumping is not boiled in the slice, the bearing of the crystallization mesh plate is increased no matter the position of the blocking is in a pre-crystallization first position or in a pre-crystallization second position, when the bearing is increased to a certain amount, the alarm program of the bearing sensing device under the crystallization mesh plate is automatically triggered, the sensor is controlled to be linked through the sensor main module, the turning plate shaft is controlled to rotate, the sliding block moves on the sliding rail, and the crystallization mesh plate is driven to slide leftwards and downwards along the sliding rail until the right short side of the mesh plate is fully overlapped on the upper pipe of the drying tower; in the process of downwards tilting the crystallization mesh plate, the slices slowly fall into the drying tower through a pipeline at the upper part of the drying tower; at the moment, the sliding block is in an active state at the bottom end of the sliding rail;

when the redundant 0.2a slices are all dropped into the drying tower, the crystallization mesh plate bearing sensing device slowly returns to the original position by itself to continue production; at the moment, the crystallization mesh plate returns to a horizontal state, and the sliding block returns to the upper end of the sliding rail to be in a fixed state;

the alarm times of the blocking situation are recorded as 1 time, and frequent blocking is carried out when the total alarm times are more than or equal to 5 or the total alarm number is more than or equal to 2 in 24 hours, so that a fan can be stopped for checking abnormality, and a crystal mesh plate is cleaned by the way; if the related alarm records and the technological process parameters are inquired, searching is carried out on an operation display screen.
