Description

Technical Field

[0001] This utility model relates to the field of acrylic acid filtration technology, and in particular to an acrylic acid pretreatment device. Background Technology

[0002] Acrylic acid is an important raw material for organic synthesis and a monomer for synthetic resins. It is miscible with water, alcohol, ether and chloroform. It is prepared from propylene obtained from oil refineries and is mostly used to manufacture acrylates such as methyl acrylate, ethyl acrylate, butyl acrylate and hydroxyethyl acrylate.

[0003] During the production of acrylic acid, various impurities may be generated or mixed in, such as unreacted monomers, catalyst residues, by-products, polymer particles, pigments, metal ions, etc. These impurities may affect the quality and performance of acrylic acid, so they need to be removed by filtration.

[0004] Chinese patent publication number CN212595583U discloses an acrylic resin feeding pretreatment device, including a mixing pipe, a vibration transmission rod, a vibration motor, a discharge valve, a mounting sleeve, a main material tank, and an auxiliary material tank. The top of the mixing pipe is connected to two feed pipes. The main material tank and the auxiliary material tank are respectively installed on top of the two feed pipes and are both connected to the feed pipes. A first throttle valve is fixedly installed on the feed pipe below the main material tank, and a second throttle valve is fixedly installed on the feed pipe below the auxiliary material tank. This patent allows for preliminary mixing of raw materials during the feeding stage of production, thereby improving the overall mixing quality of the production process. The vibration transmission rod transmits the vibration generated by the vibration motor to the mixing pipe, causing the mixing pipe to vibrate, which is beneficial for mixing the raw materials and also promotes the downward flow of the raw materials, preventing blockage inside the mixing pipe.

[0005] In some existing technologies, acrylic acid may produce or be mixed with various impurities during processing, which can easily affect the quality and performance of acrylic acid. If it is not filtered before processing, the impurities can easily clog the feed hole, making cleaning troublesome and thus affecting the processing effect and work efficiency. Utility Model Content

[0006] The main purpose of this invention is to provide an acrylic acid pretreatment device that can effectively solve the problem that in some existing technologies, acrylic acid will generate or be mixed with various impurities during processing, which can easily affect the quality and performance of acrylic acid. If it is not filtered before processing, the impurities can easily clog the feed hole, which is troublesome to clean, thus affecting the processing effect and work efficiency.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An acrylic acid pretreatment device includes a filter box, a filter mechanism fixedly connected to the inner surface of the filter box, a feed inlet fixedly connected to the top of the filter box, a vibration mechanism fixedly connected to the bottom of the filter box, and a discharge port fixedly connected to the lower side of the rear end of the filter box.

The tops of the two upper support rods are slidably connected to a primary filter plate, and the tops of the two lower support rods are slidably connected to a secondary filter plate. A scraper is slidably connected to the top of the secondary filter plate, and a mounting bracket is fixedly connected to the top of the scraper. Movable blocks are fixedly connected to the left and right ends of the mounting bracket. The inner surfaces of the two movable blocks are threaded with bidirectional threaded rods, and the outer surfaces of the two movable blocks are slidably connected to the inside of the sliding grooves. The front ends of the two bidirectional threaded rods are rotatably connected to a dual-drive motor housing.

[0010] Preferably, the top of both the primary filter plate and the secondary filter plate is fixedly connected with an anti-stick pad.

[0011] Preferably, a waste collection trough is fixedly connected to the rear end of the filter box near the primary filter plate and the secondary filter plate, and a sealing door plug is engaged with the inner surface of the rear side of the filter box near the primary filter plate and the secondary filter plate. Leak-proof baffles are symmetrically fixedly connected to the left and right sides of the inner surface of the filter box near the sliding groove.

[0012] Preferably, the front and rear ends of the two bidirectional threaded rods are rotatably connected to slide rail seats, and the opposite surfaces of the two slide rail seats are fixedly connected to the left and right sides of the outer surface of the filter box.

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

[0016] 1. In the implementation of this utility model, by setting up a filtration mechanism, it is found that impurities easily clog the filter holes when filtering acrylic acid, making cleaning troublesome. To avoid this situation, a primary filter plate and a secondary filter plate are set up. After a large amount of impurities are filtered by the primary filter plate, the quantity is reduced, leaving only a small amount of impurities that leak down with the liquid. The small amount of impurities are filtered by the secondary filter plate and remain at the top of the secondary filter plate. By moving the scraper back and forth, the impurities filtered down from the top of the secondary filter plate can be cleaned to the sealing plug. The sealing plug can be removed, and the debris can be cleaned out from the waste collection tank. The overall operation is simple and convenient, making it easy to clean the filter plates and reducing the frequency of filter plate clogging to a certain extent, thereby improving the overall work efficiency.

[0017] 2. In the implementation of this utility model, by setting up a vibration mechanism, if the material liquid is only allowed to seep naturally, the efficiency is slow. Through the vibration of the multi-dimensional vibration eccentric rotary device, the liquid can pass through the filter plate better and faster, thereby improving the overall filtration efficiency.

Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-7 As shown, an acrylic acid pretreatment device includes a filter box 1, a filter mechanism 2 fixedly connected to the inner surface of the filter box 1, a feed inlet 3 fixedly connected to the top of the filter box 1, a vibration mechanism 4 fixedly connected to the bottom of the filter box 1, and a discharge outlet 5 fixedly connected to the lower side of the rear end of the filter box 1.

[0028] The vibration mechanism 4 in this solution can be a multi-dimensional vibration eccentric rotary device in the prior art, which can provide vibration for the filtration mechanism 2 and improve the filtration speed of acrylic acid through vibration. Since it is a very mature product in the prior art, it will not be described in detail in this application.

[0029] In this embodiment, the filter box 1 and the vibration mechanism 4 are installed and fixed during implementation. The liquid enters the interior of the filter box 1 through the inlet 3 and is filtered step by step by the filter mechanism 2. The vibration mechanism 4 vibrates the filter box 1, which helps the liquid pass through the filter plates better and faster. The filtered liquid flows out through the outlet 5. Impurities remain on the top of the primary filter plate 202 and the secondary filter plate 204. The impurities on the top of the primary filter plate 202 are pushed to the sealing plug 210 by the hand 16 and pulled out so that the impurities can be cleaned out through the waste collection tank 211. The impurities on the top of the secondary filter plate 204 are scraped down to the sealing plug 210 by the scraper 205 under the drive of the dual drive motor box 209 and cleaned through the waste collection tank 211. This reduces the frequency of filter plate clogging to a certain extent, thereby improving the overall working efficiency.

[0030] For details, please refer to Figure 2 , Figure 3 and Figure 4In this embodiment, symmetrical sliding grooves 213 are arranged on the left and right sides inside the filter box 1. The filter mechanism 2 includes four support rods 201. The tops of the two upper support rods 201 are slidably connected to a primary filter plate 202, and the tops of the two lower support rods 201 are slidably connected to a secondary filter plate 204. A scraper 205 is slidably connected to the top of the secondary filter plate 204. A mounting bracket 206 is fixedly connected to the top of the scraper 205. Movable blocks 207 are fixedly connected to the left and right ends of the mounting bracket 206. The inner surface of each movable block 207 is threaded with a bidirectional threaded rod 208. The outer surfaces of both movable blocks 207 are slidably connected to the inside of the slide groove 213. The front ends of each of the two bidirectional threaded rods 208 are rotatably connected to a dual-drive motor housing 209. The front and rear ends of each of the two bidirectional threaded rods 208 are rotatably connected to slide rail seats 214. The opposing surfaces of the two slide rail seats 214 are fixedly connected to the left and right sides of the outer surface of the filter box 1. When filtering acrylic acid, impurities easily clog the filter holes, making cleaning troublesome. To avoid this situation... In this situation, by setting a support rod 201, which is located on the inner wall of the filter box 1, a primary filter plate 202 and a secondary filter plate 204 are respectively set on its top. The primary filter plate 202 is placed at an angle on the inner wall of the filter box 1, while the secondary filter plate 204 is placed flat. Because a large amount of impurities are reduced after being filtered by the primary filter plate 202, only a small amount of impurities will seep down with the liquid. The small amount of impurities are filtered by the secondary filter plate 204 and remain on the top of the secondary filter plate 204. The dual drive motor box 209 drives the bidirectional threaded rod 208, so that the bidirectional threaded rod 208 is threadedly connected to the moving block 207, thereby driving the mounting frame 206 and the scraper 205 to move on the top of the secondary filter plate 204. Through the movement of the scraper 205, the impurities filtered down from the top of the secondary filter plate 204 can be cleaned to the sealing door plug 210, which facilitates the cleaning of the filter plate and reduces the frequency of filter plate clogging to a certain extent, thereby improving the overall working efficiency.

[0031] Further reference Figure 2 In this embodiment, anti-stick pads 203 are fixedly connected to the top of both the primary filter plate 202 and the secondary filter plate 204, which can reduce the situation of material adhering to the filter plate.

[0032] Further reference Figure 2 and Figure 6In this embodiment, a waste collection trough 211 is fixedly connected to the rear end of the filter box 1 near the primary filter plate 202 and the secondary filter plate 204. A sealing door plug 210 is snapped onto the inner surface of the rear side of the filter box 1 near the primary filter plate 202 and the secondary filter plate 204. Leak-proof baffles 212 are symmetrically fixedly connected to the left and right sides of the inner surface of the filter box 1 near the slide groove 213. The sealing door plug 210 can be removed to clean out the debris from the waste collection trough 211. The overall operation is simple and convenient.

[0033] Further reference Figure 7 In this embodiment, a mounting base 215 is fixedly connected to the lower left side of the outer surface of the filter box 1. A cleaning plate 216 is engaged with the outer surface of the mounting base 215. The mounting base 215 is fixed to the lower left side of the outer surface of the filter box 1. The cleaning plate 216 is engaged with the outer surface of the mounting base 215, which makes it convenient to remove the cleaning plate 216 to clean the top of the primary filter plate 202, and helps to clean the impurities filtered from the liquid.

[0034] Further reference Figure 5 In this embodiment, the vibration mechanism 4 includes a multi-dimensional vibration eccentric rotary device 401. Buffer springs 402 are symmetrically fixed to the left and right sides of the top of the multi-dimensional vibration eccentric rotary device 401. Reinforcing seats 403 are fixedly connected to the outer surfaces of the upper and lower ends of the four buffer springs 402. If the liquid only relies on natural leakage, the efficiency is slow. The vibration of the multi-dimensional vibration eccentric rotary device 401 helps the liquid pass through the filter plate better and faster, thereby improving the overall filtration efficiency.

[0035] It should be noted that the specific installation method, circuit connection method, and control method of the dual-drive motor box used in this utility model are all conventional designs, and will not be described in detail here.

[0036] The working principle of this utility model is as follows: In use, the filter box 1 and the vibration mechanism 4 are installed and fixed. The liquid enters the interior of the filter box 1 through the inlet 3 and is filtered step by step by the filter mechanism 2. The vibration mechanism 4 vibrates the filter box 1, which helps the liquid pass through the filter plates better and faster. The filtered liquid flows out through the outlet 5. Impurities remain on the top of the primary filter plate 202 and the secondary filter plate 204. The impurities on the top of the primary filter plate 202 are pushed to the sealing plug 210 by the hand 16 and pulled out so that the impurities can be cleaned out through the waste collection tank 211. The impurities on the top of the secondary filter plate 204 are scraped down to the sealing plug 210 by the scraper 205 under the drive of the dual drive motor box 209 and cleaned through the waste collection tank 211. This reduces the frequency of filter plate clogging to a certain extent, thereby improving the overall working efficiency.
