Description

Technical Field

[0001] This utility model relates to the field of polyester resin processing technology, specifically to a cooling tower for high-level polyester resin synthesis reaction. Background Technology

[0002] High-level polyester resin, as a high-performance plastic material, is commonly used to manufacture complex-shaped, high-precision plastic products, such as electronic components, automotive parts, aerospace components, and mechanical equipment parts. Its application range is very wide. However, although high-level polyester resin has good application prospects, the waste heat gas and solid particulate waste generated during its production process have always been problems that urgently need to be solved.

[0003] In recent years, with the continuous development of related technologies, researchers in related fields have also disclosed some technical solutions to address the above-mentioned problems. For example, patent application number 201320660576.1 uses a cooling tower in the prior art to spray and cool down and filter waste heat gas and solid particulate waste contained in the waste heat gas. However, in actual operation, the production of polyester resin is continuous, so waste heat gas and solid particulate waste are constantly generated. Although the above technology can achieve the filtration of solid particulate waste, it lacks convenient and clean technical means. As the amount of filtered solid particulate waste increases, if it is not cleaned in time, the filter structure is prone to clogging, which will ultimately affect the overall efficiency of the process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a cooling tower for high-level polyester resin synthesis reactions, solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a cooling tower for high-level polyester resin synthesis reaction, including a cooling tower body and an air guide pipe installed on one side of the cooling tower body. The interior of the cooling tower body is respectively set as a spray area, a filtration area and a filling material cooling area from top to bottom. A composite filter frame plate is installed in the filtration area inside the cooling tower body. The top two sides of the composite filter frame plate are inclined surface structures, and a first filter screen is nested in each of the two inclined surface structures.

[0006] The composite filter frame plate has a semi-open groove in the middle. The front shell of the cooling tower body has a clearance groove aligned with the semi-open groove, and a collection box is snapped into the semi-open groove. The front end of the collection box passes through the clearance groove and is equipped with an outer support plate. The outer support plate is connected to the front shell of the cooling tower body, and both sides of the outer support plate are fitted with guide valve pipes that can communicate with the internal space of the collection box.

[0007] Preferably, both sides of the composite filter frame plate are provided with guide grooves facing the central axis of the composite filter frame plate, and the composite filter frame plate is fixedly nested inside the cooling tower body.

[0008] Preferably, the front end and bottom of the semi-open groove are both open structures, and a reinforcing plate and a third filter screen are nested inside the bottom of the semi-open groove. The reinforcing plate can further improve the structural strength of the composite filter frame plate, while the third filter screen can work with the first filter screen to make the entire composite filter frame plate usable for filtration.

[0009] The selected material collection box consists of a semi-open box and a second filter screen nested inside the bottom of the semi-open box. The inner wall of the bottom of the semi-open box has a sloping shape that is lower in the front and higher in the back, thereby ensuring that the subsequent cleaning water can flow out smoothly.

[0010] Preferably, the front surface of the cooling tower body is provided with threaded holes, and the interior of the outer support plate is provided with countersunk holes that can be aligned with the threaded holes. The outer support plate and the cooling tower body are detachably installed by means of screws being fitted into the countersunk holes and then screwed into the threaded holes, thereby meeting the self-cleaning requirements of the collection box being flexibly removed from the cooling tower body.

[0011] Specifically, the outer side of the bottom of the composite filter frame is provided with a double straight tooth curved plate and an electric push rod, and the output end of the electric push rod is connected to the double straight tooth curved plate for transmission. Both sides of the middle part of the composite filter frame are equipped with gear shafts through bearings. The two gear shafts can mesh with the two sides of the double straight tooth curved plate for transmission, and brush plates are installed on the top of the two gear shafts.

[0012] Preferably, a fixing seat is installed between the housing surface of the electric push rod and the reinforcing plate, and the electric push rod is waterproof to prevent water from entering and causing short circuits in its internal electronic components. The output end of the electric push rod is connected to the front end of the double straight tooth curved plate.

[0013] Preferably, the inner wall of the middle part of the double straight tooth curved plate is engaged with a slide rail installed on the bottom surface of the composite filter frame plate. The slide rail provides additional support for the double straight tooth curved plate, and there is a clearance between the double straight tooth curved plate and the composite filter frame plate to reduce the friction of the double straight tooth curved plate during movement.

[0014] The two brush plates are composed of a support rod and several rubber brush strips arranged on the bottom surface of the support rod. The rubber brush strips can effectively avoid scratches, and the brush plates can clean the first filter screen nested inside the composite filter frame plate by rotating with the corresponding gear shaft, thereby automatically cleaning the first filter screen and maintaining the long-term effective filtration function of the first filter screen.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

This utility model consists of a composite filter frame plate, a first filter screen, a collection box, an outer support plate, and two guide valves to form a multi-functional filtration and collection device. When used in combination with the cooling tower body, it can filter and collect solid particulate impurities in the exhaust gas. When a certain amount of solid particulate impurities are collected, the two guide valves can be used in combination with existing pumping equipment to flush and collect solid particulate impurities inside the collection box. During the flushing and collection process, the entire device can continue to operate, ensuring its efficiency.

[0017] 2. This utility model allows for the modular replacement of the outer support plate and the cooling tower body by means of screws, making the use of the outer support plate and the collection box more flexible.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figure 1-4 A cooling tower for high-level polyester resin synthesis reaction includes a cooling tower body 1 and an air guide pipe 2 installed on one side of the cooling tower body 1. The interior of the cooling tower body 1 is respectively set as a spray area, a filtration area and a packing material cooling area from top to bottom. A composite filter frame plate 3 is installed in the filtration area inside the cooling tower body 1. The top two sides of the composite filter frame plate 3 are inclined surface structures, and a first filter screen 4 is nested in each of the two inclined surface structures.

[0029] The composite filter frame plate 3 has guide grooves 12 on both sides facing the central axis of the composite filter frame plate 3. The composite filter frame plate 3 is fixedly nested inside the cooling tower body 1. The front end and bottom of the semi-open groove are open structures. The bottom of the semi-open groove is nested with a reinforcing plate and a third filter screen 13. The reinforcing plate can further improve the structural strength of the composite filter frame plate 3, while the third filter screen 13 can work with the first filter screen 4 to make the entire composite filter frame plate 3 capable of filtering.

[0030] The composite filter frame plate 3 has a semi-open groove in the middle. The front shell of the cooling tower body 1 has a clearance groove aligned with the semi-open groove, and a collection box 5 is snapped into the semi-open groove. The front end of the collection box 5 passes through the clearance groove and is equipped with an outer support plate 6. The outer support plate 6 is connected to the front shell of the cooling tower body 1, and both sides of the outer support plate 6 are fitted with a flow guide valve pipe 7 that can communicate with the internal space of the collection box 5.

[0031] The collection box 5 consists of a semi-open box 51 and a second filter screen 52 nested inside the bottom of the semi-open box 51. The inner wall of the bottom of the semi-open box 51 is sloping with a lower front and a higher back, which ensures that the subsequent cleaning water can flow out smoothly. The surface of the front end of the cooling tower body 1 is provided with a threaded hole, and the inside of the outer support plate 6 is provided with a countersunk hole that can be aligned with the threaded hole. The outer support plate 6 and the cooling tower body 1 are detachably installed by screwing the countersunk hole and then screwing it into the threaded hole, thereby meeting the self-cleaning requirements of the collection box 5 being flexibly removed from the cooling tower body 1.

[0032] In a specific embodiment: hot exhaust gas containing solid particulate impurities enters the cooling tower body 1 through the air guide pipe 2 and is sprayed by the existing spray mechanism inside the cooling tower body 1 to cool down and reduce dust. Then, the solid particulate impurities enter the top of the composite filter frame plate 3 along with the water droplets. Then, under the filtration of multiple first filter screens 4, the water droplets flow downward, while the solid particulate impurities are filtered onto the surface of the composite filter frame plate 3. Since both sides of the composite filter frame plate 3 are inclined surfaces, the water flow formed by the water droplets gradually converges towards the middle of the composite filter frame plate 3 as it flows down, and then enters the interior of the collection box 5 for filtration and storage.

[0033] After the entire equipment has been used for a certain period of time, the output end of the existing water pump can be connected to a guide valve pipe 7. Open the valves inside the two guide valve pipes 7, start the water pump, and the water pump will pump the external clean water through the corresponding guide valve pipe 7 to the inside of the collection box 5 for cleaning. The wastewater generated during cleaning is discharged through another guide valve pipe 7. In this way, the collected solid particulate impurities can be cleaned while the equipment continues to operate.

[0034] Example 2

[0035] Please see Figure 5-6 The outer side of the bottom of the composite filter frame plate 3 is respectively provided with a double straight tooth curved plate 9 and an electric push rod 8, and the output end of the electric push rod 8 is connected to the double straight tooth curved plate 9 in a transmission. Both sides of the middle part of the composite filter frame plate 3 are fitted with gear shafts 10 through bearings. The two gear shafts 10 can mesh with the two sides of the double straight tooth curved plate 9 respectively, and brush plates 11 are installed on the top of the two gear shafts 10.

[0036] A fixing seat is installed between the housing surface of the electric push rod 8 and the reinforcing plate. The electric push rod 8 is waterproof to prevent water from entering and causing short circuits in its internal electronic components. The output end of the electric push rod 8 is connected to the front end of the double straight tooth curved plate 9. The inner wall of the middle part of the double straight tooth curved plate 9 is fitted with a slide rail 14 installed on the bottom surface of the composite filter frame plate 3. The slide rail 14 provides additional support for the double straight tooth curved plate 9, and there is a clearance between the double straight tooth curved plate 9 and the composite filter frame plate 3 to reduce the friction of the double straight tooth curved plate 9 during movement.

[0037] Both brush plates 11 are composed of a support rod and several rubber brush strips arranged on the bottom surface of the support rod. The rubber brush strips can effectively avoid scratches. The brush plates 11 can clean the first filter screen 4 nested inside the composite filter frame plate 3 by rotating with the corresponding gear shaft 10, thereby automatically cleaning the first filter screen 4 and maintaining the long-term effective filtration function of the first filter screen 4.

[0038] In a specific embodiment: the cooling and dust removal of hot exhaust gas containing solid particulate impurities is the same as the steps in the previous embodiment 1, but the cleaning of the first filter screens 4 on both sides of the top of the composite filter frame plate 3 can be achieved by reciprocating the opening and closing of the electric push rod 8. The output end of the electric push rod 8 reciprocates to drive the double straight tooth curved plate 9 to move automatically. The reciprocating double straight tooth curved plate 9 will simultaneously mesh with the two gear shafts 10, thereby causing the two gear shafts 10 to drive their respective corresponding brush plates 11 to automatically clean the top of the two first filter screens 4, accelerating the speed at which solid particulate impurities gather in the middle of the composite filter frame plate 3.

[0039] Another method for cleaning the solid particle impurities collected inside the collection box 5 in this embodiment is to pause the cooling tower body 1, remove the screws between the outer support plate 6 and the cooling tower body 1, and then pull out the collection box 5 and the outer support plate 6 as a whole until the collection box 5 is removed from the inside of the cooling tower body 1. Then, directly pour out the solid particle impurities inside the collection box 5 or replace it with a new collection box 5.
