Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of alkyd resin production, and particularly relates to a filtering device for alkyd resin production. Background Art
[0002] As a key synthetic resin, alkyd resin occupies an important position in the industrial field. It is usually prepared from polyols, polyacids, and vegetable oils or fatty acids through a polycondensation reaction and essentially belongs to the category of oil-modified polyester resins. With its excellent film-forming properties and wide applicability, alkyd resin has been extremely widely used in many fields such as coatings, inks, adhesives, etc., and is an essential material in the production process of related products.
[0003] Currently, in the production process of alkyd resin (liquid), the filtering link is a key process in the production of products such as coatings and inks, and its filtering effect directly affects the quality and performance of the final product. However, there are many problems with the current filtering methods used in alkyd resin production.
[0004] For example: Although the traditional multi-stage filter screen filtering method reduces costs to a certain extent, it faces many inconveniences in actual operation. This type of filtering method usually sets the filter screen inside the device. When it is necessary to clean or replace the filter screen, complex disassembly and assembly procedures are required to take out the filter screen. This process is not only cumbersome, consuming a large amount of time and manpower, but also seriously affects the overall production work efficiency.
[0005] In summary, the filtering device for alkyd resin production in the prior art has obvious deficiencies in terms of cost and operation convenience. Summary of the Invention
[0006] The present invention provides a filtering device for alkyd resin production, which can solve the problems of obvious deficiencies in terms of cost and operation convenience of the filtering device for alkyd resin production in the prior art.
[0007] To achieve the above object, according to an embodiment of the first aspect of the present invention, a filtering device for alkyd resin production is proposed, including an outer tank body and a tank cover arranged on the top surface of the outer tank body; An inner filter tank is arranged inside the outer tank body, and the inner filter tank includes an upper tank section and a lower tank section which are respectively arranged up and down inside the outer tank body; It further includes: A filter screen assembly, arranged inside the upper tank section and the lower tank section, for filtering alkyd resin; A connecting and separating mechanism is used for separating and connecting the upper tank section and the lower tank section. The connecting and separating mechanism includes a plurality of mounting seats one fixedly installed outside the lower tank section in an array, hook rods rotatably arranged in the ports at one end of each mounting seat through rotating shafts, return springs fixedly installed on the inner walls of one end of each hook rod and the mounting seat, a plurality of stop rods arranged in the outer tank body in an array, and a snap ring fixedly sleeved outside the lower tank section and cooperating with the hook rods for clamping. A notch for cooperating with the rotation of the hook rod is arranged on the top surface of each stop rod.
[0008] A further improvement lies in that a placement notch one is opened on the top surface of the upper tank section, a placement notch two is opened on the top surface of the lower tank section, and the filter screen assembly includes a coarse filter screen arranged in the placement notch one and a fine filter screen arranged in the placement notch two.
[0009] A further improvement lies in that a plurality of horizontally distributed micro cylinders are embedded in the outer tank body, mounting seats two are fixedly installed on the inner walls below the micro cylinders respectively, the bottom side of each stop rod is rotatably connected to the mounting seat two through a rotating shaft, a connecting seat is fixedly installed on the upper side of each stop rod, and the rod end of each micro cylinder is rotatably installed in the port of the connecting seat through a rotating shaft.
[0010] A further improvement lies in that a rubber shock absorption platform is fixedly installed on the inner bottom surface of the outer tank body, an installation groove for cooperating with the installation of the lower tank section is penetrated through the rubber shock absorption platform, a plurality of limit columns are fixedly installed at the bottom edge of the lower tank section in an array, and a plurality of limit openings for cooperating with the installation of the limit columns are opened on the inner wall of the installation groove.
[0011] A further improvement lies in that the inner part of the outer tank body is designed with a narrower upper part and a wider lower part. After the inner filter tank is placed in the outer tank body, the top surface height of the upper tank section is flush with the top surface height of the outer tank body.
[0012] A further improvement lies in that there is also a pressing component arranged on the outer tank body. The pressing component includes a plurality of auxiliary seats fixedly installed outside the outer tank body in an array, stud bolts rotatably arranged in the ports of each auxiliary seat, and pressing pieces screwed on each stud bolt. A bayonet for cooperating with the installation of the stud bolt is penetrated through the edge of the tank cover, and the shape of the bayonet is adapted to the shape of the stud bolt for the stud bolt to pass through and achieve cooperation.
[0013] A further improvement lies in that there is also a sealing structure. The sealing structure is used for sealing between the tank cover and the upper tank section and between the upper tank section and the lower tank section when the tank cover covers the upper tank section to prevent the substances in the tank from leaking; The sealing structure includes a silica gel pressing ring fixedly installed on the bottom surface of the tank cover, sealing rings connected to the inner walls of the ports of the placement notch one and the placement notch two, and a rubber pressing ring fixedly connected to the bottom edge of the upper tank section.
[0014] A further improvement lies in that the raised positions of the silica gel pressing ring and the rubber pressing ring also face downward; the silica gel pressing ring is connected to the first placement notch in an interference fit manner, and the rubber pressing ring is connected to the second placement notch in an interference fit manner.
[0015] A further improvement lies in that there is also additionally a dispersion assembly, which includes a rotating rod rotatably arranged on the bottom surface of the can lid, a liquid distribution plate fixedly installed at the bottom end of the rotating rod, and a DC servo motor fixedly installed on the top surface of the can lid with the main shaft connected to the rotating rod. A number of liquid distribution notches are penetrated through the liquid distribution plate.
[0016] Compared with the prior art, the beneficial effects of the present invention are: (1) By designing the connection and separation mechanism in the present invention, several hook rods outside the upper tank section are respectively inserted into the bottoms of the corresponding snap rings of the lower tank section. Then, the whole inner filter tank is placed into the outer tank body, and the lower tank section falls into the installation groove of the rubber shock-absorbing table. At this time, a plurality of limit posts arrayed at the bottom edge of the lower tank section will be respectively inserted into the limit ports to form a stable limit clamping structure, effectively preventing bottom displacement. And through the action of the inner baffle in the outer tank body, the connection between the upper tank section and the lower tank section can be supported. Subsequently, the operator places another sealing ring in the first placement notch and covers the can lid, so that the silica gel pressing ring is snapped into the notch. Then, each stud is turned up to the vertical state, snapped into the corresponding snap port of the can lid, and the pressing member is screwed. Under the downward pressing action of the pressing member, the bottom surface of the silica gel pressing ring will squeeze and fix the coarse filter screen, and the bottom surface of the rubber pressing ring will squeeze and fix the fine filter screen, realizing synchronous fixation without individual fixing operations, improving the convenience of assembly. At the same time, the silica gel pressing ring and the rubber pressing ring will mutually squeeze the sealing rings in the two grooves, further enhancing the sealing performance, thereby effectively preventing the leakage of alkyd resin during the filtering process; (2)During the filtering operation of the present invention, the alkyd resin is introduced into the upper tank section and falls into the liquid separation tray. Subsequently, the DC servo motor is started. Under the driving action of the motor, the rotating rod starts to rotate, thereby driving the liquid separation tray to rotate synchronously. When the liquid separation tray is in a rotating state, the alkyd resin liquid can be evenly sprinkled on the coarse filter screen arranged below through a number of liquid separation slots provided on it. This uniform liquid sprinkling effect through the rotation of the liquid separation tray and the liquid separation slots avoids the direct impact of the alkyd resin on the coarse filter screen with a large impact force, thereby effectively preventing the local collapse of the coarse filter screen. At the same time, the evenly sprinkled liquid makes it difficult for impurities to get stuck in the mesh holes of the coarse filter screen, greatly improving the service life of the coarse filter screen. In addition, this design is also beneficial to improving the filtering effect of the primary filtering link and laying a good foundation for the subsequent fine filtering process. Under the action of gravity, the alkyd resin liquid flows through the coarse filter screen to complete the primary filtering, and then falls into the fine filter screen at the tank mouth of the lower tank section for secondary filtering. Through this dual filtering method, impurities with different particle sizes in the alkyd resin liquid can be removed step by step. This design not only effectively controls the cost but also significantly improves the production quality of the alkyd resin liquid.
[0017] (3)When the filter screen assembly in the inner filter tank needs to be disassembled, cleaned or maintained in the present invention. If you choose to separately remove the upper tank section for operation, first start each micro cylinder to make the rod body of each micro cylinder extend, and adjust the stop rod to a vertical angle. Subsequently, lift the entire inner filter tank. During this process, due to the function of the notch on the stop rod, the hook rod will rotate and compress the return spring, causing the hook rod to expand outward. When the hook rod expands, it will disengage from the snap ring on the lower tank section, separating the lower tank section from the upper tank section. At this time, the upper tank section can be separately lifted out to facilitate the separate flushing or replacement of the coarse filter screen inside it. In addition, since a rubber shock-absorbing platform is provided at the bottom inside the outer tank body, this design can effectively reduce the amplitude generated by vibration when the upper tank section is lifted out and put back, protecting the stability of the equipment. On the other hand, if you choose to operate on the entire inner filter tank, after synchronously lifting the upper tank section and the lower tank section, you can adjust the angle of the stop rod without rotating the adjusting screw. In this way, the entire inner filter tank will be lifted out as a whole, so that the inner filter tank and the coarse filter screen and fine filter screen inside it can be flushed or replaced simultaneously, improving the maintenance efficiency.

Detailed implementation manners
[0020] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0021] As Figures 1 to 9 shown, a filtering device for alkyd resin production includes an outer tank body 2, a tank cover 21 arranged on the top surface of the outer tank body 2, and a liquid guide pipeline 211 vertically arranged on the tank cover 21. The liquid guide pipeline 211 is connected to an external input pipeline for inputting alkyd resin into the outer tank body 2 for filtering; An inner filter tank 22 is arranged inside the outer tank body 2. The inner filter tank 22 includes an upper tank section 201 and a lower tank section 202 which are respectively arranged up and down inside the outer tank body 2. An installation notch one 203 is formed in the top surface of the upper tank section 201, and an installation notch two 204 is formed in the top surface of the lower tank section 202; A filter screen assembly 6, the filter screen assembly 6 includes a coarse filter screen 61 arranged in the installation notch one 203 and a fine filter screen 62 arranged in the installation notch two 204; A connection and separation mechanism 3, the connection and separation mechanism 3 includes a plurality of mounting seats one 31 fixedly installed in an array on the outside of the lower tank section 202, hook rods 32 rotatably arranged in the ports of each mounting seat one 31 through a rotating shaft, return springs 33 fixedly installed on the inner wall of the ports of each hook rod 32 and the mounting seat one 31, a plurality of stop rods 34 arranged in an array inside the outer tank body 2, and a snap ring 35 fixedly sleeved on the outside of the lower tank section 202 and cooperating with the hook rod 32 for clamping. A notch 341 for cooperating with the rotation of the hook rod 32 is arranged on the top surface of each stop rod 34; Specifically, a plurality of horizontally distributed micro-cylinders 36 are embedded on the outer tank body 2. Mounting seats two 37 are respectively fixedly installed on the inner walls below the micro-cylinders 36. The bottom side of each stop rod 34 is rotatably connected to the mounting seat two 37 through a rotating shaft. A connecting seat 38 is fixedly installed on the upper side of each stop rod 34. The rod end of each micro-cylinder 36 is rotatably installed in the port of the connecting seat 38 through a rotating shaft. With this design, the stop rod 34 is adjusted to a vertical angle by the elongation of the rod body of the micro-cylinder 3. Subsequently, the entire inner filter tank 22 is lifted. During this process, due to the action of the notch 341 on the stop rod 34, the hook rod 32 will rotate and compress the return spring 33, causing the hook rod 32 to expand outwards. When the hook rod 32 expands, it will disengage from the snap ring 35 on the lower tank section 202, so that the lower tank section 202 is separated from the upper tank section 201. At this time, the upper tank section 201 can be separately lifted out for separately flushing or replacing the coarse filter screen 61 inside it. On the other hand, if the entire inner filter tank 22 is selected for operation, after synchronously lifting the upper tank section 201 and the lower tank section 202, the rod body of the micro-cylinder 3 can be contracted to adjust the angle of the stop rod 34. In this way, the entire inner filter tank 22 will be lifted out as a whole, so that the inner filter tank 22 and the coarse filter screen 61 and the fine filter screen 62 inside it can be simultaneously flushed or replaced, improving the maintenance efficiency; As a preferred implementation, a rubber shock-absorbing table 23 is fixedly installed on the inner bottom surface of the outer tank body 2. Since the rubber shock-absorbing table 23 is provided at the inner bottom of the outer tank body 2, this design can effectively reduce the amplitude generated by vibration when the upper tank section 201 is lifted out and put back, protecting the stability of the equipment; As a preferred embodiment, an installation groove 231 for fitting the installation of the lower tank section 202 is formed through the rubber shock-absorbing table 23. A number of arrayed limit posts 232 are fixedly installed at the bottom edge of the lower tank section 202. A number of limit ports 233 for fitting the installation of the limit posts 232 are formed on the inner wall of the installation groove 231. By respectively snapping the multiple arrayed limit posts 232 at the bottom edge of the lower tank section 202 into the limit ports 233, a stable limit clamping structure is formed, effectively preventing bottom displacement. In addition, through the action of the inner blocking rod 34 in the outer tank body 2, the connection between the upper tank section 201 and the lower tank section 202 can be supported, improving the stability during the filtering operation; It should be noted that a feed pipe 212 is fixedly installed at the bottom of the lower tank section 202, and a through groove is formed at the bottom of the outer tank body 2. After the lower tank section 202 is clamped in the installation groove 231, the bottom feed pipe 212 passes through the through groove and is connected to the external output pipeline for outputting alkyd resin; As a preferred embodiment, the inner part of the outer tank body 2 is designed with a narrower upper part and a wider lower part, which is convenient for installing and connecting the components of the separation mechanism 3. After the inner filter tank 22 is placed in the outer tank body 2, the top surface height of the upper tank section 201 is flush with the top surface height of the outer tank body 2, which is convenient for the extrusion and fixation of the tank cover 21; The pressing assembly 1 is arranged on the outer tank body 2. The pressing assembly 1 includes a number of arrayed auxiliary seats 12 fixedly installed outside the outer tank body 2, a stud 11 rotatably arranged in the port of each auxiliary seat 12, and a pressing member 13 threaded on each stud 11. A bayonet 14 for fitting the installation of the stud 11 is formed through the edge of the tank cover 21. The shape of the bayonet 14 is adapted to the shape of the stud 11 for the stud 11 to pass through and achieve cooperation. The pressing assembly 1 is used to press the tank cover 21 on the outer tank body 2. By rotating the stud 11, the pressing member 13 moves along the stud 11. Under the downward pressing action of the pressing member 13, the bottom surface of the silica gel pressing ring 41 presses and fixes the coarse filter screen 61, and the bottom surface of the rubber pressing ring 43 presses and fixes the fine filter screen 62, realizing synchronous fixation without individual fixing operations, improving the convenience of assembly.
[0022] As Figures 3 to 9 shown, in this embodiment, on the basis of the above embodiment, it further includes: a sealing structure 4. The sealing structure 4 is used to achieve the sealing between the tank cover 21 and the upper tank section 201 and between the upper tank section 201 and the lower tank section 202 when the tank cover 21 covers the upper tank section 201, preventing the leakage of substances in the tank; The sealing structure 4 includes a silica gel pressing ring 41 fixedly installed on the bottom surface of the tank cover 21, a sealing ring 42 connected to the inner walls of the ports of the first placement notch 203 and the second placement notch 204, and a rubber pressing ring 43 fixedly connected to the bottom edge of the upper tank section 201. Among them, the protruding positions of the silica gel pressing ring 41 and the rubber pressing ring 43 face downward; the outer wall of the silica gel pressing ring 41 fits with the inner wall of the sealing ring 42 in the first placement notch 203, and the outer wall of the rubber pressing ring 43 fits with the inner wall of the sealing ring 42 in the second placement notch 204; when the tank cover 21 is closed on the upper tank section 201 and after the upper tank section 201 and the lower tank section 202 are combined, the outer wall of the silica gel pressing ring 41 is in close contact with the inner wall of the sealing ring 42, the bottom surface at the edge of the silica gel pressing ring 41 is in close contact with the upper tank section 201 and the top surface of the sealing ring 42, and the silica gel pressing ring 41 presses on the outer frame surface of the coarse filter screen 61; at the same time, the rubber pressing ring 43 is in close contact with the sealing ring 42 on the inner wall of the second placement notch 204, the bottom surface at the edge of the rubber pressing ring 43 is in close contact with the sealing ring 42 and the top surface of the lower tank section 202, and the rubber pressing ring 43 presses on the outer frame surface of the fine filter screen 62. By making the silica gel pressing ring 41 and the rubber pressing ring 43 squeeze the sealing rings 42 in the two slots, the sealing performance is further improved, thus effectively preventing the leakage of alkyd resin during the filtering process; As Figure 4 and Figure 5 shown, in this embodiment, on the basis of the above embodiment, it further includes: a dispersion assembly 5. The dispersion assembly 5 includes a rotating rod 51 rotatably arranged on the bottom surface of the tank cover 21, a liquid distribution disk 52 fixedly installed at the bottom end of the rotating rod 51, and a DC servo motor 53 fixedly installed on the top surface of the tank cover 21 and connected to the rotating rod 51 by the main shaft. A plurality of liquid distribution notches 521 are provided through the liquid distribution disk 52. When the liquid distribution disk 52 rotates, the liquid is evenly sprinkled on the coarse filter screen 61 below through the liquid distribution notches 521. Through the rotation of the liquid distribution disk 52 and the uniform liquid sprinkling effect of the liquid distribution notches 521, the direct impact of the alkyd resin on the coarse filter screen 61 with a large impact force is avoided, thus effectively preventing the local collapse phenomenon of the coarse filter screen 61. At the same time, the evenly sprinkled liquid makes it difficult for impurities to get stuck in the mesh holes of the coarse filter screen 61, greatly improving the service life of the coarse filter screen 61.
[0023] As Figures 1 to 9 shown, in this embodiment, it should also be noted that the actual sizes of the various components in the application document are selected and installed before implementation according to the actual on-site requirements. In addition, it should be reminded that this application document only improves the obvious deficiencies in terms of cost and operation convenience of the existing filtering device for alkyd resin production, and does not involve other aspects; the working principle of the filtering device for alkyd resin production is introduced as follows: When the solution of the present invention is used, first, the on-site operator places the fine filter screen 62 into the port of the placement notch two 204 of the lower tank section 202. Subsequently, a sealing ring 42 is placed in the notch, and then the upper tank section 201 is erected so that the rubber pressing ring 43 at the bottom is snapped into the notch. When placing the upper tank section 201, several hook rods 32 on its outer part will respectively be snapped into the bottom of the corresponding snap rings 35 of the lower tank section 202 to realize the connection of the inner filter tank 22. Then, the whole inner filter tank 22 is placed into the outer tank body 2, and the lower tank section 202 falls into the installation groove 231 of the rubber shock-absorbing table 23. At this time, a plurality of limiting posts 232 arrayed at the bottom edge of the lower tank section 202 will respectively be snapped into the limiting openings 233 to form a stable limiting and clamping structure, effectively preventing the bottom from shifting. And through the action of the inner baffle 34 in the outer tank body 2, the connection part between the upper tank section 201 and the lower tank section 202 can be supported. Meanwhile, the feed pipe 212 at the bottom of the lower tank section 202 passes through the through groove at the bottom of the outer tank body 2 and is connected to the external output pipeline for the subsequent output of alkyd resin.
[0024] Subsequently, the operator places another sealing ring 42 in the placement notch one 203 and covers the tank cover 21 so that the silica gel pressing ring 41 is snapped into the notch. Then, each stud 11 is turned up to the vertical state, snapped into the corresponding bayonet 14 of the tank cover 21, and the pressing member 13 is screwed. Under the downward pressing action of the pressing member 13, the bottom surface of the silica gel pressing ring 41 will squeeze and fix the coarse filter screen 61, and the bottom surface of the rubber pressing ring 43 will squeeze and fix the fine filter screen 62 to realize synchronous fixation, eliminating the need for individual fixation operations and improving the convenience of assembly. Meanwhile, the silica gel pressing ring 41 and the rubber pressing ring 43 will mutually squeeze the sealing rings 42 in the two grooves, further enhancing the sealing performance, thereby effectively preventing the leakage of alkyd resin during the filtration process. During the filtration operation, the alkyd resin to be filtered is conveyed into the upper tank section 201 of the inner filter tank 22 by using the liquid guiding pipeline 211. After the alkyd resin enters the upper tank section 201, it will fall into the liquid distribution tray 52 along the trend. Subsequently, the DC servo motor 53 is started. Under the driving action of the motor, the rotating rod 51 starts to rotate, and then drives the liquid distribution tray 52 to rotate synchronously. When the liquid distribution tray 52 is in a rotating state, the alkyd resin liquid can be evenly sprinkled on the coarse filter screen 61 arranged below through several liquid distribution notches 521 arranged thereon. Through the rotation of the liquid distribution tray 52 and the uniform liquid sprinkling action of the liquid distribution notches 521, the direct impact of the alkyd resin on the coarse filter screen 61 with a large impact force is avoided, thus effectively preventing the local collapse phenomenon of the coarse filter screen 61. Meanwhile, the uniformly sprinkled liquid makes it difficult for impurities to get stuck in the mesh holes of the coarse filter screen 61, greatly improving the service life of the coarse filter screen 61.
[0025] In addition, this design is also beneficial to improving the filtering effect of the primary filtering stage, laying a good foundation for the subsequent fine filtering process. Under the action of gravity, the alkyd resin liquid flows through the coarse filter screen 61 to complete the preliminary filtering, and then falls onto the fine filter screen 62 at the mouth of the lower tank section 202 for secondary filtering. Through this dual filtering method, impurities with different particle sizes in the alkyd resin liquid are removed step by step. This design not only effectively controls the cost but also significantly improves the production quality of the alkyd resin liquid.
[0026] When it is necessary to disassemble, clean or maintain the filter screen assembly 6 in the inner filter tank 22, the operation method is as follows: If you choose to separately remove the upper tank section 201 for operation, first adjust the stop lever 34 to the vertical angle by extending the rod body of the micro cylinder 3. Then, lift the entire inner filter tank 22. During this process, due to the notch 341 on the stop lever 34, the hook lever 32 will rotate and compress the return spring 33, causing the hook lever 32 to expand outward. When the hook lever 32 expands, it will disengage from the snap ring 35 on the lower tank section 202, separating the lower tank section 202 from the upper tank section 201. At this time, the upper tank section 201 can be separately lifted out to facilitate separate flushing or replacement of the coarse filter screen 61 inside it. In addition, since there is a rubber shock-absorbing platform 23 at the bottom inside the outer tank body 2, this design can effectively reduce the amplitude generated by vibration when the upper tank section 201 is lifted out and put back, protecting the stability of the equipment. On the other hand, if you choose to operate on the entire inner filter tank 22, after synchronously lifting the upper tank section 201 and the lower tank section 202, the rod body of the micro cylinder 3 can be contracted to adjust the angle of the stop lever 34. In this way, the entire inner filter tank 22 will be lifted out as a whole, so that the inner filter tank 22 and the coarse filter screen 61 and fine filter screen 62 inside it can be flushed or replaced simultaneously, improving the maintenance efficiency.
[0027] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
