Description

Technical Field

[0001] This utility model relates to the field of polycarboxylate superplasticizer technology, specifically to a device for synthesizing functional monomers of polycarboxylate superplasticizer. Background Technology

[0002] Polycarboxylate superplasticizer functional monomers are functional monomers used in the synthesis of polycarboxylate mother liquor. Based on the concept of molecular design, they are unsaturated monomers synthesized using organic synthesis techniques that can be used for free radical polymerization. Their molecular structure differs from both unsaturated alcohol polyoxyethylene ethers and smaller monomers such as acrylic acid and hydroxyethyl acrylate.

[0003] For example, the authorization announcement number "CN217940190U" is titled "A Synthesis Device for Polycarboxylate Superplasticizers." This device can heat the input water when needed and filter out impurities, thus ensuring the device's operation and improving its working capacity. Currently, polycarboxylate superplasticizer synthesis devices use top-mounted water filtration and heating to remove impurities and maintain water temperature. However, filtration relies on a filter screen to remove impurities. In existing polycarboxylate superplasticizer synthesis devices, the area above the filter screen is a closed processing box. Therefore, impurities filtered out by the filter screen remain inside the processing box, accumulating and becoming difficult to remove. Over time, this can cause blockages, hindering the normal operation of the polycarboxylate superplasticizer synthesis device. Utility Model Content

[0004] The purpose of this invention is to solve the problem of poor performance of existing polycarboxylate superplasticizer synthesis devices, and to propose a synthesis device for functional monomers of polycarboxylate superplasticizers.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A synthesis apparatus for polycarboxylate superplasticizer functional monomers is designed, comprising a base, a reactor body, and an observation window. The reactor body is fixedly installed above the base, and the observation window is fixedly installed on the outer wall of the reactor body. Water heating and conveying control structures are provided on both sides of the top of the reactor body, a synthesis stirring structure is provided on the inner side of the reactor body, and a stabilizing support structure is provided at the lower end of the reactor body.

[0007] The water heating and conveying control structure includes horizontal plates and conveying pipes. Two horizontal plates are fixedly installed on the top two sides of the reactor body. A processing box is fixedly installed above the two horizontal plates. Two conveying pipes are fixedly connected to the lower ends of the two processing boxes. Solenoid valves are fixedly installed inside the two conveying pipes. Multiple heating rods are fixedly installed at the lower inner ends of the two processing boxes.

[0008] The two treatment boxes are equipped with a cleanable filter structure on top. The cleanable filter structure includes a top cover and a filter layer. The two top covers are movably connected to the top of the treatment boxes. Locking bolts are threaded to both sides of the two top covers. The two filter layers are fixedly installed on the inner wall of the treatment boxes. Filter paper is movably placed on top of the two filter layers. A water inlet pipe is fixedly connected to the top of the two top covers. A handle is fixedly installed on the upper outer wall of the two top covers.

[0009] The lower ends of the two locking bolts are threaded to the inner edge of the treatment box, and the lower ends of the two water inlet pipes are positioned opposite the top of the filter paper.

[0010] The synthesis stirring structure includes a motor and an inner liner. The inner liner is fixedly installed on the inner wall of the reactor body. The motor is fixedly installed at the top of the reactor body. The lower end of the motor's output shaft is fixedly connected to a rotating shaft through a reducer. A stirring blade is installed on the outer wall of the rotating shaft. The edge of the stirring blade is movably connected to the inner wall of the inner liner. Two feeding pipes are fixedly connected to the top of the reactor body.

[0011] The stabilizing support structure includes a control valve and counterweights. Multiple counterweights are movably installed on the lower inner side of the reactor body. The control valve is fixedly installed below the reactor body. A discharge port is fixedly connected to the lower end of the control valve. A receiving chamber is opened at the lower end of the discharge port. Two stabilizing columns are fixedly connected to both sides of the outer wall of the reactor body.

[0012] The present invention discloses a synthesis device for polycarboxylate superplasticizer functional monomers, which has the following advantages: the top cover can be fastened to the top of the treatment tank using a handle, and then the top cover can be fixed to the lower treatment tank using locking bolts on both sides. The filter paper is made of hemp fiber filter paper and is placed in the filter layer. In this way, the water flow will pass through the double-layer filtration of the filter paper and the filter layer, which not only improves the filtration effect, but also allows the top cover to be opened by loosening the locking bolts and removing and replacing the filter paper afterward. This effectively prevents the problem of inconvenient cleaning of filter impurities inside the closed treatment tank, and improves the use effect of the synthesis device for polycarboxylate superplasticizer functional monomers.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] Please see Figure 1-6 In this embodiment, a synthesis device for polycarboxylate superplasticizer functional monomers includes a base 1, a reactor body 2, and an observation window 3. The reactor body 2 is fixedly installed above the base 1, and the observation window 3 is fixedly installed on the outer wall of the reactor body 2. The observation window 3 is made of transparent tempered glass and can effectively observe the internal process of polycarboxylate superplasticizer functional monomer synthesis. Water heating and conveying control structures 4 are provided on both sides of the top of the reactor body 2, a synthesis stirring structure 6 is provided on the inner side of the reactor body 2, and a stabilizing support structure 7 is provided at the lower end of the reactor body 2.

[0023] The water heating and conveying control structure 4 includes two horizontal plates 41 and two conveying pipes 44. The two horizontal plates 41 are fixedly installed on both sides of the top of the reactor body 2. The horizontal plates 41 are horizontally welded to the top of the reactor body 2. A processing box 42 is fixedly installed above the two horizontal plates 41. The horizontal plates 41 can be used to support and fix the processing box 42. Two conveying pipes 44 are fixedly connected to the lower end of the two processing boxes 42. Solenoid valves 45 are fixedly installed inside the two conveying pipes 44. The processing box 42 is supplemented with external water resources through the upper water inlet pipe 54. Then, the heating rod 43 is energized to generate heat to heat the water. At the same time, the upper part of the processing box 42 can filter impurities in the water. Finally, after the lower solenoid valve 45 is opened, the heated water is conveyed down the conveying pipe 44 into the reactor body 2. Multiple heating rods 43 are fixedly installed on the lower inner side of the two processing boxes 42.

[0024] A cleanable filter structure 5 is provided above the two treatment boxes 42. The cleanable filter structure 5 includes a top cover 51 and a filter layer 55. The two top covers 51 are movably connected to the top of the treatment box 42. Locking bolts 52 are threaded on both sides of the two top covers 51. The top covers 51 can be fastened to the top of the treatment box 42 by using a handle 53. Then, the top covers 51 and the lower treatment box 42 can be installed and fixed by using the locking bolts 52 on both sides. The two filter layers 55 are fixedly installed on the inner wall of the treatment box 42. Filter paper 56 is movably placed on top of the two filter layers 55. The filter paper 56 is made of hemp fiber filter paper.

[0025] The filter paper 56 is placed in the filter layer 55, so that the water flow will be filtered by the double layer of filter paper 56 and filter layer 55, which not only improves the filtration effect, but also allows the filter paper 56 to be removed and replaced after the locking bolt 52 is loosened and the top cover 51 is opened by the handle 53. The top of the two top covers 51 is fixedly connected to the water inlet pipe 54, and the handle 53 is fixedly installed on the upper outer wall of the two top covers 51. Since the filter paper 56 is above the filter layer 55, it can catch the filtered impurities and make it easy to replace. The lower ends of the two locking bolts 52 are threaded to the inner edge of the treatment box 42, and the lower ends of the two water inlet pipes 54 are set opposite to the upper part of the filter paper 56.

[0026] The top cover 51 can be fastened to the top of the treatment box 42 using the handle 53, and then the top cover 51 can be installed and fixed to the lower treatment box 42 using the locking bolts 52 on both sides. The filter paper 56 is made of hemp fiber filter paper and is placed in the filter layer 55. In this way, the water flow will be filtered by the double layer of filter paper 56 and filter layer 55, which not only improves the filtration effect, but also allows the top cover 51 to be opened by loosening the locking bolts 52 and using the handle 53 to remove and replace the filter paper 56. This can effectively prevent the problem of difficult cleaning of filter impurities inside the closed treatment box and improve the use effect of the polycarboxylate superplasticizer functional monomer synthesis device.

[0027] The synthesis stirring structure 6 includes a motor 61 and an inner liner 65. The inner liner 65 is fixedly installed on the inner wall of the reactor body 2, and the motor 61 is fixedly installed on the top of the reactor body 2. The motor 61 is a servo motor. When selecting a motor, you can choose a motor model that meets the usage requirements. The lower end of the output shaft of the motor 61 is fixedly connected to a rotating shaft 63 through a reducer. The stirring blades 64 are installed on the outer wall of the rotating shaft 63.

[0028] The edge of the stirring blade 64 is movably connected to the inner wall of the inner liner 65. The inner liner 65 is made of stainless steel with good corrosion resistance and sealing performance. Two feeding pipes 62 are fixedly connected to the top of the reactor body 2. The feeding pipes 62 can pour various raw materials of polycarboxylate superplasticizer functional monomers from above into the reactor body 1 below. The motor 61 is connected to the power supply and started. The motor 61 can drive the rotating shaft 63 below to rotate, thereby driving the stirring blade 64 to mix and react various raw materials and heated water.

[0029] Working principle:

[0030] The use of functional monomers in the synthesis of polycarboxylic acid mother liquor can optimize the molecular structure of polycarboxylic acid mother liquor. By linking them to the main chain structure, the polymerization of polycarboxylic acid is changed from the original binary or ternary copolymerization to multi-component copolymerization, thereby optimizing the molecular structure of polycarboxylic acid.

[0031] Functional monomers can be used to synthesize different types of polycarboxylate superplasticizers, such as water-reducing, comprehensive, slump-retaining, and slow-release agents. They are suitable for heated or room-temperature processes. In specific applications, they can replace macromonomers or small monomers such as acrylic acid and hydroxyethyl acrylate in equal or greater quantities.

[0032] Results of feedwater treatment for the synthesis unit of polycarboxylate superplasticizer functional monomers:

[0033] The horizontal plate 41 is horizontally welded to the top of the reactor body 2. The horizontal plate 41 can be used to support and fix the treatment box 42. The treatment box 42 is supplemented with external water resources through the upper water inlet pipe 54. Then, the heating rod 43 is powered on to generate heat to heat the water. At the same time, the upper part of the treatment box 42 can filter impurities in the water. Finally, after opening the lower solenoid valve 45, the heated water is transported down to the reactor body 2 through the feed pipe 44.

[0034] The water filtration and cleaning structure of the synthesis device for polycarboxylate superplasticizer functional monomers:

[0035] The top cover 51 can be fastened to the top of the treatment box 42 using the handle 53, and then the top cover 51 can be installed and fixed to the lower treatment box 42 using the locking bolts 52 on both sides. The filter paper 56 is made of hemp fiber filter paper and is placed in the filter layer 55. In this way, the water flow will be filtered by the double layer of filter paper 56 and filter layer 55, which not only improves the filtration effect, but also allows the top cover 51 to be opened by loosening the locking bolts 52 and using the handle 53 to remove and replace the filter paper 56. This effectively prevents the problem of difficult cleaning of the filtered impurities inside the closed treatment box.

[0036] Synthesis process of the apparatus for synthesizing functional monomers of polycarboxylate superplasticizer:

[0037] The feeding pipe 62 can pour various raw materials of polycarboxylate superplasticizer functional monomers into the reactor body 1 below. Connect the power supply to start the motor 61. The motor 61 can drive the rotating shaft 63 below to rotate, which in turn drives the stirring blade 64 to mix and react the various raw materials and heated water.

[0038] Example 2:

[0039] Please see Figure 1-6 In this embodiment, a synthesis device for a polycarboxylate superplasticizer functional monomer includes a stabilizing support structure 7 comprising a control valve 71 and a counterweight 74. Multiple counterweights 74 are movably installed on the inner side of the lower end of the reactor body 2. The counterweights 74 are made of large-mass concrete blocks. The counterweights 74 are placed below the reactor body 2 to stabilize the lower end of the reactor body 2. The control valve 71 is fixedly installed below the reactor body 2.

[0040] After the polycarboxylate superplasticizer and functional monomers are fully mixed and stirred with water inside the reactor body 2, the control valve 71 is opened to discharge the finished polycarboxylate superplasticizer functional monomers downwards along the discharge port 72. The staff can hold the container and collect the polycarboxylate superplasticizer functional monomers inside the receiving chamber 73. The lower end of the control valve 71 is fixedly connected to the discharge port 72, and the lower end of the discharge port 72 is provided with the receiving chamber 73.

[0041] Two stabilizing columns 75 are fixedly connected to both sides of the outer wall of the reactor body 2. The stabilizing columns 75 are made of high-strength stainless steel and welded to both sides of the base 1 and the reactor body 2. In this way, the stabilizing columns 75 can improve the overall stability of the reactor body 1.

[0042] Working principle:

[0043] The counterweight 74 is made of a large-mass concrete block. The counterweight 74 is placed below the reactor body 2 to stabilize the lower end of the reactor body 2.
