[0002] The pre-extraction tank is a kind of equipment needed to be used in the production process of nylon engineering plastics and nylon differentiated fibers. It works in conjunction with the extraction tower to effectively extract the monomers and oligomers that need to be extracted from the raw material slices, so that after the extraction operation, raw materials that meet the production requirements can be obtained. It is a very important production equipment in chemical production activities.

[0003] With the continuous use of existing pre-extraction tanks, pre-extraction tanks play a very important role in chemical production. They are mainly used in conjunction with extraction towers. The use process in conjunction with extraction towers is as follows: the slices in the extraction tower are extracted from top to bottom, and the hot desalted water in the extraction tower countercurrently extracts the slices from bottom to top, thereby removing the monomers and oligomers contained in the slices. Then the extraction water flows out from the top of the tower and continues to flow to the pre-extraction tank, where the slices are pre-extracted and then transferred to the extraction tower. Since the extraction needs to be carried out at a certain temperature, the traditional pre-extraction tank cannot effectively keep the raw materials in the reaction warm, resulting in low reaction efficiency and inability to effectively collect the extraction water. Therefore, it is necessary to design a circulating heat-insulating pre-extraction tank that is convenient for collecting extraction water to address the above problems. Summary of the invention

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1-7 The present invention provides a technical solution: a circulating heat-insulating pre-extraction tank for facilitating the collection of extracted water, comprising a tank body 1, a material inlet 2, a functional port 3, a bile duct connection port 4, a bile duct body 5, a guide cone 6, a positioning cone 7, a water outlet pipe 8, a lower cone barrel 9, a thermometer port 10, a material outlet 11, a water inlet pipe 12, a top cover 13, an outer pipe 14, a steam inlet 15, a transfer pipe 16, a storage barrel 17, a condensed water outlet 18, a circulation pipe 19, a baffle plate 20 and a functional hole 21, a material inlet 2 is arranged at the center of the top of the tank body 1, and the functional port 3 and the bile duct connection port 4 are installed at the top of the tank body 1, and the bile duct connection port 4 is connected to the bile duct body 5, a guide cone 6 is fixed to the bottom end of the bile duct body 5, and the guide cone 6 is connected to the positioning cone 7, and the positioning cone 7 is fixed to the water outlet pipe 8 located at the inner part of the tank body 1. At the top, the water outlet pipe 8 is installed on the side wall of the tank body 1, the lower cone barrel 9 is fixed at the bottom end of the tank body 1, and the thermometer port 10 is installed on the side wall of the lower cone barrel 9, and the bottom end of the lower cone barrel 9 is provided with a material outlet 11, a water inlet pipe 12 is installed on the side wall of the lower cone barrel 9, and a top cover 13 is installed at the top end of the water inlet pipe 12 located in the lower cone barrel 9, an outer tube 14 is fixed on the outer wall of the tank body 1, and a steam inlet 15 is provided at the top end of the outer tube 14, and a condensate outlet 18 is provided at the bottom end of the outer tube 14, a baffle plate 20 is fixed on the inner wall of the outer tube 14, and a functional hole 21 is opened on the baffle plate 20, the steam inlet 15 is connected with the transfer pipe 16, and the transfer pipe 16 is arranged on the outer wall of the storage barrel 17, and the bottom end of the storage barrel 17 is connected with the condensate outlet 18, and a circulation pipe 19 is installed on the storage barrel 17.

[0025] In this example, the inclination angle between the front view section and the vertical plane of the outer wall of the guide cone 6 and the inner wall of the top opening of the positioning cone 7 is 35°, and the guide cone 6 is tightly fitted with the positioning cone 7. The above structural design allows the conical structure at the bottom end of the guide cone 6 to be stably fitted with the conical groove structure opened at the top of the positioning cone 7, thereby achieving the guiding and positioning effect of the bile duct body 5, and can effectively control the extraction water to enter the water outlet pipe 8 through the positioning cone 7, and finally achieve the effect of conveniently discharging the upper layer of extraction water, so that the discharged extraction water can enter the extraction tower again for continuous extraction operation, so that the continuous extraction operation can be carried out smoothly;

[0026] The lower cone barrel 9 is connected to the tank body 1 by welding, and the height of the lower cone barrel 9 is lower than the height of the tank body 1, and the angle formed by the side walls of the conical part of the bottom of the lower cone barrel 9 is 45°. The above structural design allows the lower cone barrel 9 to be stably connected to the tank body 1, and the shape design of the lower cone barrel 9 allows the added raw material slices to fully react with the extraction water added to the water inlet pipe 12 in a smaller space, and the extracted raw material slices can be more concentratedly gathered at the bottom of the lower cone barrel 9, which is convenient for discharge and collection through the material outlet 11;

[0027] The thermometer port 10 is tilted downward, and the top opening of the thermometer port 10 is higher than the top of the top cover 13. The above structural design allows the thermometer installed in the thermometer port 10 to more intuitively and accurately monitor the temperature of the extraction water added to the tank body 1 and the lower cone barrel 9 by the water inlet pipe 12 to react with the raw material slices, so as to facilitate real-time adjustment and ensure that the extraction reaction in the device can proceed normally and stably.

[0028] The water inlet pipe 12 and the top cover 13 are welded, and the angle between the water inlet pipe 12 and the horizontal plane is 45°, and the angle between the two sides of the top cover 13 in the front view section is 90°. The structural design of the top cover 13 can prevent the raw material slices from falling directly into the water inlet pipe 12 and blocking the water inlet pipe 12, and can make the extraction water discharged from the bottom to the top through the water inlet pipe 12 flow evenly around, ensuring that the extraction water can fully contact with the sliced ​​raw materials, so that the extraction operation can be carried out smoothly;

[0029] The outer tube 14 and the transfer tube 16 are spirally distributed on the outer walls of the tank body 1 and the storage barrel 17, respectively, and the front view cross-section of the outer tube 14 is semicircular, and the inner wall of the outer tube 14 is densely and staggeredly distributed with baffles 20, and the middle of the baffle 20 is provided with a functional hole 21 with a top view cross-section shape of an isosceles trapezoid. The above structural design enables the steam in the outer tube 14 and the transfer tube 16 to fully heat and insulate the tank body 1 and the storage barrel 17, respectively, and the staggered arrangement of the baffles 20 can effectively slow down the air flow in the outer tube 14, and the design of the functional holes 21 ensures the fluidity of the steam, so that the baffle 20 will not excessively hinder the flow of the steam;

[0030] The blocking plate 20 and the outer tube 14 are an integrated structure, and the thickness of the wall of the arc-shaped portion of the outer tube 14 is greater than the thickness of the wall of the portion in contact with the tank body 1, and the width of the blocking plate 20 is less than half of the inner diameter of the outer tube 14. The above-mentioned structural design requires a longer distance for the temperature of the steam in the outer tube 14 to be transferred to the outside, so the transfer speed is slower. The thicker tube wall plays a certain role in heat preservation, while the thinner portion is in contact with the outer side of the tank body 1, ensuring that the heat of the steam can reach the tank body 1 after a shorter distance, so that the heat can be transferred to the tank body 1 faster, reducing the ineffective loss of steam temperature and improving the efficiency of heating and heat preservation. The design of the blocking plate 20 cooperates with the functional hole 21 to fully ensure that the steam will not be excessively obstructed, thereby ensuring the fluidity of the steam.

[0031] Working principle: When using this device, first Figure 1 The water inlet pipe 12 is connected to the discharge structure and the water pump at the top of the extraction tower, the transfer pipe 16 is connected to the external steam generator, and the circulation pipe 19 is connected to the external water pump. The above-mentioned extraction tower, water pump and steam generator are all existing mature technologies, which are well known to those skilled in the art and will not be described in detail here;

[0032] Then the material outlet 11 is closed, and the raw material slices are added into the tank body 1 through the material inlet 2. An exhaust constant pressure structure is installed in the functional port 3, which is the same as the structure used in the existing pre-extraction tank and is not described in detail here. The extraction tower works normally and the extraction water is discharged into the lower cone barrel 9 through the water inlet pipe 12 under the action of the water pump through the discharge structure at the top, and is extracted with the added raw material slices;

[0033] Water is added to the storage barrel 17 through the circulation pipe 19, and the steam generator connected to the transfer pipe 16 is operated through the external power supply circuit. The water pump simultaneously provides the water in the storage barrel 17 to the steam generator through the circulation pipe 19. When the steam generated by the steam generator passes through the transfer pipe 16 wound around the outside of the storage barrel 17, the water in the storage barrel 17 is preheated, the temperature of the water to be processed by the steam generator is increased, and the time for the steam generator to generate steam is shortened. Since the capacity of the storage barrel 17 is small, it will not absorb too much heat, and there is no blocking structure inside the transfer pipe 16, the steam can pass quickly without losing too much heat. Next, the steam enters the outer tube 14 through the steam inlet 15, and the flow rate is slowed down by the blocking plate 20 in the outer tube 14, so that the steam can The outer tube 14 and the tank body 1 perform sufficient heat exchange, so that the temperature inside the tank body 1 and the lower cone barrel 9 can be maintained at a relatively stable level. Due to the large amount of heat transfer in the steam, the steam condenses into water at the tail of the outer tube 14, and is discharged into the storage barrel 17 through the condensate outlet 18 for collection, waiting to be transported to the steam generator through the circulation pipe 19 to generate steam again. The steam generated by the steam generator is preheated by the transfer pipe 16 to the condensate that has just entered the storage barrel 17. The storage barrel 17, the circulation pipe 19, the external steam generator, the transfer pipe 16, the steam inlet 15, the outer tube 14 and the condensate outlet 18 constitute a closed circulation loop, and the above-mentioned operation process is repeated to perform cyclic heating and heat preservation operations on the tank body 1;

[0034] After the reaction is completed, the bolt at the bile duct connection port 4 can be adjusted to drive the bile duct body 5 to move upward, and the guide cone 6 can be separated from the positioning cone 7, so that the top opening of the water outlet pipe 8 is exposed, the upper layer of extracted water can be removed and collected, and the material outlet 11 can be opened to collect the raw material slices after the reaction.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
