Description

Technical Field

[0001] This utility model relates to the technical field of polycarboxylate superplasticizer production equipment, and in particular to a raw material feeding device for producing polycarboxylate superplasticizer. Background Technology

[0002] Liquid polycarboxylate superplasticizers are currently the mainstream form of superplasticizers in concrete engineering. They are typically pale yellow to light brown transparent liquids with an active ingredient content of 15%-30%. At 25°C, their viscosity is 50-300 mPa·s, exhibiting good fluidity. Production primarily utilizes aqueous solution polymerization, adding main-chain monomers such as acrylic acid, side-chain monomers such as TPEG / HPEG, along with ammonium persulfate initiators, mercaptoacetic acid chain transfer agents, and supplemented with sodium hydroxide for neutralization, deionized water as a solvent, and small amounts of defoamers and preservatives.

[0003] During the production of liquid polycarboxylate superplasticizer, a dosing device is needed to add the raw material of liquid polycarboxylate superplasticizer into the production equipment. However, the existing dosing device has a fixed dosing height, which can only meet the needs of production equipment of a single height and size, and thus cannot meet the needs of liquid polycarboxylate superplasticizer production of different scales.

[0004] To address the aforementioned technical deficiencies, a solution is proposed: by adjusting the overall length of the adjusting sleeve and adjusting rod, the working height of the outlet pipe can be adjusted to meet the needs of production equipment of different sizes and heights, thereby satisfying the production needs of liquid polycarboxylate superplasticizers of different scales. Utility Model Content

[0005] The purpose of this invention is to provide a device for adding raw materials for the production of polycarboxylate superplasticizer, in order to solve the problems mentioned above.

[0006] The objective of this utility model can be achieved through the following technical solution: a raw material feeding device for producing polycarboxylate superplasticizer, comprising: The dosing assembly includes a base, an adjustment sleeve fixed to the top of the base, an adjustment rod movably disposed inside the adjustment sleeve, a mounting strip fixed to the top of the adjustment rod, a delivery pump mounted on the top of the base, a hose mounted at the outlet of the delivery pump, a rigid pipe mounted at one end of the hose and passing through the mounting strip, and an outlet pipe mounted at one end of the rigid pipe. The fixing assembly includes two sets of movable holes formed on the outer wall of the adjusting sleeve, multiple sets of positioning holes formed on the outer wall of the adjusting rod, two sets of positioning rods correspondingly and movably disposed inside the two sets of movable holes, a connecting strip fixed to one end of the two sets of positioning rods, and two sets of first springs correspondingly disposed outside the two sets of positioning rods.

[0007] Preferably, the ends of both sets of positioning rods furthest from the connecting strip are engaged inside the corresponding positioning holes.

[0008] Preferably, one end of each of the two sets of first springs is fixed to the connecting strip, and the other end of each of the two sets of first springs is fixed to the adjusting sleeve.

[0009] Preferably, the inner wall of the adjusting sleeve is provided with a limiting groove, and the outer wall of the adjusting rod is fixed with a limiting block that is movably disposed inside the limiting groove.

[0010] Preferably, it also includes a sealing assembly, which includes a connecting plate fixed inside the outlet pipe, a through hole and a through hole formed on the top of the connecting plate, a connecting rod movably disposed inside the through hole, a push plate and a sealing plate correspondingly fixed at both ends of the connecting rod, and a second spring disposed outside the connecting rod.

[0011] Preferably, the two ends of the second spring are fixed to the sealing plate and the connecting plate respectively.

[0012] Preferably, the sealing plate abuts against the bottom of the outlet pipe.

[0013] The beneficial effects of this utility model are: 1. By using the connecting strip to pull the two sets of positioning rods, the two sets of positioning rods will move within the two sets of movable holes and the corresponding two sets of positioning holes. The first spring will also stretch. When one end of the two sets of positioning rods disengages from the corresponding two sets of positioning holes, the fixing of the adjusting sleeve and adjusting rod can be released. Therefore, the adjusting rod can be driven to move inside the adjusting sleeve, thereby adjusting the working height of the outlet pipe. After the working height of the outlet pipe is adjusted, the connecting strip is released. At this time, under the reaction force of the first spring, the two sets of positioning rods will be driven to move within the two sets of movable holes. When one end of the two sets of positioning rods engages with the corresponding two sets of positioning holes, the adjusting sleeve, adjusting rod, and outlet pipe can be fixed. Compared with the existing ones, this utility model can adjust the overall length of the adjusting sleeve and adjusting rod, thereby achieving the purpose of adjusting the working height of the outlet pipe, so as to meet the use of production equipment of different sizes and heights, and thus meet the needs of liquid polycarboxylate superplasticizer production of different scales.

[0014] 2. When the liquid polycarboxylate superplasticizer raw material passes through the outlet pipe, it applies pressure to the push plate and sealing plate. At this time, the connecting rod will descend within the perforation, and the second spring will also stretch. When the sealing plate is in contact with the bottom of the outlet pipe, the liquid polycarboxylate superplasticizer raw material will enter the production equipment through the outlet pipe. After the addition of the liquid polycarboxylate superplasticizer raw material is completed, the push plate and sealing plate lose the pressure of the liquid polycarboxylate superplasticizer raw material. Under the reaction action of the second spring, the connecting rod will rise within the perforation. When the sealing plate is in contact with the bottom of the outlet pipe, the outlet pipe can be sealed to prevent dust, impurities, or even flying insects in the air from entering the outlet pipe and causing blockage, thereby ensuring the working efficiency of the outlet pipe. Compared with the existing technology, this utility model can automatically seal the outlet pipe after the addition of the liquid polycarboxylate superplasticizer raw material, preventing dust, impurities, or even flying insects in the air from entering the outlet pipe and causing blockage, thereby ensuring the working efficiency of the outlet pipe.

Detailed Implementation

[0017] 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.

[0018] Example 1: The application background of this utility model is based on the fact that the feeding height of the existing feeding device is fixed, which can only meet the needs of production equipment of a single height and size, and thus cannot meet the needs of liquid polycarboxylate superplasticizer production of different scales. The technical solution of this utility model is to address the problem of how to adjust the feeding height of the feeding device to meet the needs of production equipment of different heights and sizes as well as liquid polycarboxylate superplasticizer production of different scales. Please see Figure 1 , Figure 3 , Figure 4 As shown, this embodiment is a raw material dosing device for producing polycarboxylate superplasticizer, including: a dosing component 100, comprising a base 101, an adjusting sleeve 102 fixed to the top of the base 101, an adjusting rod 103 movably disposed inside the adjusting sleeve 102, an mounting strip 104 fixed to the top of the adjusting rod 103, a delivery pump 105 mounted on the top of the base 101, a flexible hose 106 mounted at the outlet of the delivery pump 105, a rigid pipe 107 mounted at one end of the flexible hose 106 and passing through the mounting strip 104, and an outlet pipe 108 mounted at one end of the rigid pipe 107; and a fixing component 300, including two sets of movable holes 301 formed on the outer wall of the adjusting sleeve 102, and a fixed hole 301 formed on the adjusting rod 102. The outer wall of 103 has multiple sets of positioning holes 302, two sets of positioning rods 303 correspondingly and movably disposed inside the two sets of movable holes 301, a connecting strip 304 fixed to one end of the two sets of positioning rods 303, and two sets of first springs 305 correspondingly disposed outside the two sets of positioning rods 303. The ends of the two sets of positioning rods 303 away from the connecting strip 304 are all engaged inside the corresponding positioning holes 302. One end of the two sets of first springs 305 is fixed to the connecting strip 304, and the other end of the two sets of first springs 305 is fixed to the adjusting sleeve 102. The inner wall of the adjusting sleeve 102 is provided with a limiting groove 109, and the outer wall of the adjusting rod 103 is fixed with a limiting block 110 movably disposed inside the limiting groove 109. By using the connecting strip 304 to pull the two sets of positioning rods 303, the two sets of positioning rods 303 will move within the two sets of movable holes 301 and the corresponding two sets of positioning holes 302. The first spring 305 will also stretch. When one end of the two sets of positioning rods 303 disengages from the corresponding two sets of positioning holes 302, the fixing of the adjusting sleeve 102 and the adjusting rod 103 can be released. Therefore, the adjusting rod 103 can be driven to move inside the adjusting sleeve 102, thereby adjusting the working height of the outlet pipe 108. After the working height of the outlet pipe 108 is adjusted, the connecting strip 304 is released. The reaction force of the first spring 305 will drive the two sets of positioning rods 303 to move within the two sets of movable holes 301. When one end of the two sets of positioning rods 303 is engaged with the corresponding two sets of positioning holes 302, the adjusting sleeve 102, adjusting rod 103, and outlet pipe 108 can be fixed. Compared with the existing ones, this utility model can adjust the overall length of the adjusting sleeve 102 and adjusting rod 103, thereby achieving the purpose of adjusting the working height of the outlet pipe 108, so that it can meet the use of production equipment of different sizes and heights, and thus meet the production use of liquid polycarboxylate superplasticizer of different scales. With the cooperation of the limiting groove 109 and the limiting block 110, the movement path of the adjusting rod 103 can be limited, thereby preventing the outlet pipe 108 from rotating and ensuring the accuracy of the addition of liquid polycarboxylate superplasticizer raw materials by the outlet pipe 108.

[0019] Example 2: Please refer to Figure 1 , Figure 2 As shown, this embodiment is a raw material feeding device for producing polycarboxylate superplasticizer, and also includes a sealing assembly 200. The sealing assembly 200 includes a connecting plate 201 fixed inside the outlet pipe 108, a through hole 203 and a through hole 202 opened on the top of the connecting plate 201, a connecting rod 204 movably disposed inside the through hole 203, a push plate 205 and a sealing plate 206 correspondingly fixed at both ends of the connecting rod 204, and a second spring 207 disposed outside the connecting rod 204. The two ends of the second spring 207 are fixed to the sealing plate 206 and the connecting plate 201 respectively, and the sealing plate 206 abuts against the bottom of the outlet pipe 108. When the liquid polycarboxylate superplasticizer raw material passes through the outlet pipe 108, it applies pressure to the push plate 205 and the sealing plate 206. At this time, the connecting rod 204 will descend within the perforation 203, and the second spring 207 will also extend. When the sealing plate 206 is no longer in contact with the bottom of the outlet pipe 108, the liquid polycarboxylate superplasticizer raw material will enter the production equipment through the outlet pipe 108. After the addition of the liquid polycarboxylate superplasticizer raw material is completed, the push plate 205 and the sealing plate 206 lose the pressure of the liquid polycarboxylate superplasticizer raw material. Under the reaction of the second spring 207, the connecting rod 204 will move downward within the perforation 203. The device moves upward within 203. When the sealing plate 206 comes into contact with the bottom of the outlet pipe 108, the outlet pipe 108 is sealed, preventing dust, impurities, or even flying insects from entering the outlet pipe 108 and causing blockage. This ensures the working efficiency of the outlet pipe 108. Compared with existing devices, this invention can automatically seal the outlet pipe 108 after the liquid polycarboxylate superplasticizer raw material is added, preventing dust, impurities, or even flying insects from entering the outlet pipe 108 and causing blockage, thus ensuring the working efficiency of the outlet pipe 108.

[0020] In summary, please refer to the following: Figures 1-4First, install the base 101 into the designated working area, and then adjust the working height of the outlet pipe 108 according to the height of the production equipment. Specifically, use the connecting strip 304 to pull the two sets of positioning rods 303. At this time, the two sets of positioning rods 303 will move within the two sets of movable holes 301 and the corresponding two sets of positioning holes 302. The first spring 305 will also stretch. When one end of the two sets of positioning rods 303 disengages from the corresponding two sets of positioning holes 302, the fixing of the adjusting sleeve 102 and the adjusting rod 103 can be released. The adjusting rod 103 is driven to move inside the adjusting sleeve 102, thereby adjusting the working height of the outlet pipe 108. After the working height of the outlet pipe 108 is adjusted, the connecting strip 304 is released. At this time, under the reaction force of the first spring 305, the two sets of positioning rods 303 will move in the two sets of movable holes 301. When one end of the two sets of positioning rods 303 is engaged in the corresponding two sets of positioning holes 302, the adjusting sleeve 102, adjusting rod 103, and outlet pipe 108 can be fixed. Then the raw material pipe and the conveying pump 10 are connected. Connect to the inlet of pipe 5 and start the delivery pump 105. The liquid polycarboxylate superplasticizer material inside the raw material pipe will enter the outlet pipe 108 through the hose 106 and the rigid pipe 107. When the liquid polycarboxylate superplasticizer material passes through the outlet pipe 108, it will apply pressure to the push plate 205 and the sealing plate 206. At this time, the connecting rod 204 will move downward within the perforation 203, and the second spring 207 will also move in a stretching motion. When the sealing plate 206 is not in contact with the bottom of the outlet pipe 108, the liquid polycarboxylate superplasticizer material will enter through the outlet pipe 108. The liquid polycarboxylate superplasticizer is fed into the production equipment. After the liquid polycarboxylate superplasticizer is added, the push plate 205 and the sealing plate 206 lose the pressure of the liquid polycarboxylate superplasticizer. Under the reaction of the second spring 207, the connecting rod 204 will move upward in the perforation 203. When the sealing plate 206 abuts against the bottom of the outlet pipe 108, the outlet pipe 108 can be sealed to prevent dust, impurities, or even flying insects in the air from entering the outlet pipe 108 and causing blockage, thereby ensuring the working efficiency of the outlet pipe 108.

[0021] As can be seen from Embodiments 1 and 2, on the one hand, the overall length of the adjusting sleeve 102 and the adjusting rod 103 can be adjusted to achieve the purpose of adjusting the working height of the outlet pipe 108, so that it can meet the use of production equipment of different sizes and heights, and thus meet the production use of liquid polycarboxylate superplasticizer of different scales; on the other hand, after the raw material of liquid polycarboxylate superplasticizer is added, the outlet pipe 108 can be automatically sealed to prevent dust, impurities or even flying insects in the air from entering the interior of the outlet pipe 108 and causing blockage of the outlet pipe 108, thereby ensuring the working efficiency of the outlet pipe 108.

[0022] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
