Description

Technical Field

[0001] The utility model relates to the technical field of concrete raw material compounding devices, in particular to a polycarboxylate water-reducing agent compounding system. Background Art

[0002] Concrete water reducer is a chemical substance added to improve and adjust the performance of concrete. The application of water reducer in engineering is receiving more and more attention, and the addition of water reducer plays a certain role in improving the performance of concrete.

[0003] At present, most of the compounding production of concrete water-reducing agents is completed in the main factory buildings of the production enterprises. Basically, one factory supplies water-reducing agent products to one province. The products compounded in the main factory buildings of the production enterprises are then transported to various places for on-site use.

[0004] At present, the construction sites of high-speed railways and highways are relatively remote, and the transportation volume of compounded finished water-based agents is large, resulting in increased transportation costs and untimely delivery. Moreover, if the demand for compounded water-reducing agents on site changes (for example, the water-reducing agent formula needs to be adjusted according to on-site conditions), the compounded water-reducing agent products delivered from remote locations will not be supplied in a timely manner and will not meet the requirements.

[0005] The above problems can be avoided by using compounding at the construction site or a compounding point nearby. However, if the on-site compounding is done manually or semi-manually, not only will the labor cost increase, but the manual operation will be too cumbersome and prone to errors. In addition, the traditional on-site or near-site compounding process of polycarboxylic acid compounding is: first quantitatively extract liquid materials and store them in storage tanks - add solid materials to liquid materials - stir evenly - inspect - load the truck, resulting in low compounding efficiency and low output; in addition, temporary compounding sites may have water and power supply difficulties, resulting in the inability to compound water reducers on site.

[0006] However, if a large compounding automated production line is built near the project, there will be problems with capital investment, time consumption, and relocation after the project is completed. Utility Model Content

[0030] The utility model provides Figure 1-3 A polycarboxylate water-reducing agent compounding system is shown, and its technical scheme is as follows:

[0031] The polycarboxylate water-reducing agent compounding system comprises a plurality of raw material feeding subsystems 30, an automatic control device 40, an air compressor 50, and a liquid transport vehicle or storage tank 10; the raw material feeding subsystem 30 comprises a raw material tank 301, the raw material tank 301 is provided with a feeding pipe, a discharging pipe, an air intake pipe, an exhaust pipe, a pressure transmitter 302 and a liquid level transmitter 303 for respectively detecting the pressure and liquid level in the raw material tank 301, and the air intake pipe, the exhaust pipe, and the feeding pipe are respectively provided with an air intake valve 305, an exhaust valve 304, and a feeding valve 306, and the upper edge of the discharging pipe is in a direction away from the discharging port of the raw material tank 301. A discharge valve 307, a regulating valve 308, and a flow meter 309 are sequentially provided; the discharge pipes of several raw material feeding subsystems 30 are connected to the feed end of the mixer 20, and the discharge end of the mixer 20 is connected to the inside of the liquid transport vehicle or the storage tank 10; wherein the air intake pipe of the raw material tank 301 is connected to the air compressor 50, so that the compressed air enters the raw material tank 301 through the air intake pipe; the automatic control device 40 is electrically connected to the pressure transmitter 302, the liquid level transmitter 303, the exhaust valve 304, the air intake valve 305, the feed valve 306, the discharge valve 307, the regulating valve 308, and the flow meter 309. Preferably, the raw material feeding subsystem 30 includes an A raw material feeding subsystem 31, a B raw material feeding subsystem 32, and a C raw material feeding subsystem 33.

[0032] Specifically, if Figure 1-3As shown in this embodiment, the raw material feeding subsystem 30 includes an A raw material feeding subsystem 31, a B raw material feeding subsystem 32, and a C raw material feeding subsystem 33; wherein the A raw material feeding subsystem 31 corresponds to an A raw material tank 311, a first feeding pipeline, a first discharging pipeline, a first air intake pipeline, a first exhaust pipeline, a first pressure transmitter 312, a first liquid level transmitter 313, a first air intake valve 315, a first exhaust valve 314, a first feeding valve 316, a first discharging valve 317, a first regulating valve 318, and a first flow meter 319; the B raw material feeding subsystem 32 corresponds to a B raw material tank 321, a second feeding pipeline, a second discharging pipeline , a second air intake pipeline, a second exhaust pipeline, a second pressure transmitter 322, a second liquid level transmitter 323, a second air intake valve 325, a second exhaust valve 324, a second feed valve 326, a second discharge valve 327, a second regulating valve 328, and a second flow meter 329; the C raw material feeding subsystem 33 correspondingly includes a C raw material tank 331, a third feed pipeline, a third discharge pipeline, a third air intake pipeline, a third exhaust pipeline, a third pressure transmitter 332, a third liquid level transmitter 333, a third air intake valve 335, a third exhaust valve 304, a third feed valve 336, a third discharge valve 337, a third regulating valve 338, and a third flow meter 339;

[0033] The feeding process of the polycarboxylate water-reducing agent compounding system provided by the embodiment of the utility model is as follows:

[0034] Turn on the power of the automatic control device 40, set the relevant feeding parameters, for example, the feeding ratio of each raw material tank 301 (i.e., the flow ratio of each flow meter 309), the pressure setting value of each raw material tank 301, etc.; click the start button on the automatic control device 40, the automatic control device 40 controls the air compressor 50 to start, and the compressed air enters the raw material tank 301 (including the A raw material tank 311, the B raw material tank 321, and the C raw material tank 331) through the intake valve 305 (including the first intake valve 315, the second intake valve 325, and the third intake valve 335), and the automatic control device 40 adjusts the pressure of the raw material tank 301 to the pressure of the raw material tank 301. The air intake valve 305 is adjusted to make the raw material tank 301 enter a constant pressure state, wherein the process of adjusting the constant pressure state is: the pressure of the corresponding raw material tank 301 is detected by the pressure transmitter 302 (including the first pressure transmitter 312, the second pressure transmitter 322, and the third pressure transmitter 332) and fed back to the automatic control device 40, when the pressure reaches the set value, the automatic control device 40 controls to close the air intake valve 305, and when it is less than the set value, the air intake valve 305 is opened, and such feedback adjustment action is performed during the feeding process, so that the pressure in each raw material tank 301 is kept in a constant pressure state;

[0035] When the raw material tanks 301 (including A raw material tank 311, B raw material tank 321, C raw material tank 331) reach the set pressure for the first time, the mixer 20 and the discharge valves 307 (including the first discharge valve 317, the second discharge valve 327, and the third discharge valve 337) of each raw material tank 301 are started again, and the automatic control system on the automatic control device 40 automatically adjusts the opening size of the regulating valve 308 (including the first regulating valve 318, the second regulating valve 328, and the third regulating valve 338) of each raw material tank 301 according to the set value of the discharge amount of each raw material tank 301, so that each raw material slowly enters the mixer 20 according to the set proportion, and the mixed material in the mixer 20 enters the on-site liquid transport vehicle or storage tank 10 until the set weight of the added material is completed, and then all work (i.e., the constant pressure adjustment work of the raw material tank 301, the discharge work of the raw material tank 301, etc.) is automatically stopped.

[0036] Among them, the control method of discharging each raw material tank 301 into the mixer 20 according to the set ratio is: the discharging time of each raw material tank 301 is consistent (that is, the opening time of the discharge valve 307 is consistent), and the discharge ratio of each raw material tank 301 is controlled by controlling the discharge flow rate and ratio of each raw material tank 301. The flow meter 309 detects the discharge flow rate and feeds back to the automatic control device 40. According to the preset flow rate, the controller controls the opening size of the regulating valve 308 to realize the discharge flow rate control of each raw material tank 301. The ratio is: if raw material A needs to add 50KG, raw material C needs to add 500KG, and raw material D needs to add 2000KG, the time consumed for their addition is the same, and each flow meter 309 is used to measure the amount and speed of addition. The ratio of each flow is the discharge ratio. The flow ratio measured by the first flow meter 319, the second flow meter 329, and the third flow meter 339 is 1:10:40.

[0039] Through the design of the reserved pipe and the first pneumatic valve 320, the A raw material can flow directly into the mixer 20 for mixing without passing through the A raw material tank 311 and adjusting the flow rate; for example, when the raw material in the A raw material tank 311 is water, in some construction sites with poor conditions and no water resources, when the polycarboxylic acid water-reducing agent compounding system is transported to the site as a whole, the A raw material tank 311 can be stored with water in advance and transported to the site for use; if the water resources on site are sufficient, there is no need to store water, and the A raw material tank 311 can be directly transported empty, and the reserved pipe can be connected to the external water source on site for use; such a design can adapt to the needs of different scenarios and save transportation costs.

[0065] When the first raw material tanks 301 (including A raw material tank 311, B raw material tank 321, C raw material tank 331) all reach the set pressure, the mixer air inlet valve 21 and the discharge valves 307 (including the first discharge valve 317, the second discharge valve 327, and the third discharge valve 337) of each raw material tank 301 are started again, and the automatic control system on the automatic control device 40 will automatically adjust the opening size of the regulating valve 308 (including the first regulating valve 318, the first regulating valve 318, and the first regulating valve 318) of each raw material tank 301 according to the set value of the discharge amount of each raw material tank 301 and the feedback information of the flow meter 309, so that each raw material slowly enters the mixer 20 according to the set proportion, and the mixed material in the mixer 20 enters the liquid transport vehicle or storage tank 10 until the set weight of the added material is completed, and then all work (i.e., the constant pressure adjustment work of the raw material tank 301, the discharge work of the raw material tank 301, etc.) is automatically stopped.

[0066] If there is a small solid material to be thrown, the small material is thrown through the auxiliary device 60: the automatic control device 40 controls the first auxiliary device valve 65 to be closed, and the fuel pump 62, the second auxiliary device valve 66, the third auxiliary device valve 67, and the fourth auxiliary device valve 68 are opened, and the small material is thrown into the feeding hopper 61, and the fuel pump 62 pumps the small material into the liquid transport vehicle or the storage tank 10;

[0067] After the feeding is completed, if auxiliary mixing is required: the automatic control device 40 controls the first auxiliary device valve 65, the fuel pump 62, and the fourth auxiliary device valve 68 to open, and closes the second auxiliary device valve 66 and the third auxiliary device valve 67. The fuel pump 62 draws the material out of the liquid transport vehicle or storage tank 10, and circulates it to the liquid transport vehicle or storage tank 10 through the auxiliary device discharge pipe 64 to assist in material mixing.

[0068] It should be noted that:

[0069] The automatic control device 40 used has a wide range of optional models, for example, existing controllers such as PLC and DCS can be used, which are existing technologies, and the working principles of controlling various types of machinery or production processes are not described in detail. For example, a PLC controller has a programmable memory for storing programs inside, executing user-oriented instructions such as logical operations, sequential control, timing, counting and arithmetic operations, and controlling various types of machinery or production processes through digital or analog input / output, which are existing technologies, and the working principles are not described in detail.

[0070] The exhaust valve 304, intake valve 305, feed valve 306, discharge valve 307, regulating valve 308, first pneumatic valve 320, mixer intake valve 21, first auxiliary device valve 65, second auxiliary device valve 66, third auxiliary device valve 67, fourth auxiliary device valve 68, etc. used are all existing valves that can be driven by electrical energy and whose opening and opening degree can be controlled by a controller. Those skilled in the art can select the existing valves by themselves.

[0071] The pressure transmitter 302, the liquid level transmitter 303, the flow meter 309 and other detection components are existing devices, and the automatic control device 40 cooperates with them and performs process control. The working principle is existing technology and will not be repeated here.

[0072] The fuel air compressor and the fuel pump 62 are also existing devices powered by fuel. The automatic control device 40 cooperates with them and the working principle of process control is the existing technology, which will not be repeated here.

[0073] The solar power generation device 70 and the 24V livestock battery 80 are also existing devices. The automatic control device 40 cooperates with them and the working principle of process control is the existing technology, which will not be repeated here.

[0074] In summary, compared with the prior art, the polycarboxylate water-reducing agent compounding system provided by the utility model includes the following novelties, practicalities and beneficial effects:

[0075] 1. Compared with the traditional compounding system, the compounding system provided in this application does not have a compounding kettle, but uses a transport vehicle or storage tank delivered to the site instead of a compounding kettle, which can save the equipment investment cost of the production line, and at the same time eliminates the loading or warehousing time of the compounded materials, thereby improving production efficiency.

[0076] 2. Compared with the traditional compounding system, the compounding system device provided in the present application is equipped with a fuel air compressor, which mainly functions to pressurize each raw material tank during the production process, and through the cooperation of the pressure transmitter, the valve on the raw material tank, the automatic control device, and the fuel air compressor, it performs detection-feedback-adjustment automatic control, and plays a constant pressure role in the production process; various liquid raw materials are pumped by constant pressure instead of pumping, which reduces the maintenance of vulnerable equipment and improves production efficiency.

[0077] 3. Compared with the traditional compounding system, the compounding system provided in this application can be loaded in a standard container, is easy to move, and can be transported to the site for on-site compounding, thereby improving production efficiency and the quality of compounded products.

[0078] 4. Compared with the traditional compounding system, the compounding system provided by this application installs a solar power generation device on the top of the container to charge the 24V battery and provide electricity for the instrument and automatic control device. The compounding system can also be produced without an external power supply and is suitable for various complex environments with ready-made construction. At the same time, the raw material tank can reserve water sources that are difficult to supply on site in advance, and transport the water sources directly to the site to solve the problem that the conditions at the temporary compounding site do not meet the electricity and water supply.

[0079] 5. Compared with the traditional compounding system, when the compounding system provided by the present application is used, various raw material mother liquors and water can be evenly (the same as the synthesis dropwise addition process) and simultaneously enter the mixer in the compounding system (the mixer air inlet valve is designed to add pressurized air to the place where various liquid materials gather (i.e., the mixer) to play the role of traditional stirring, which can shorten the homogenization time).

[0080] 6. The compounding system provided in the present application performs detection-feedback-adjustment automatic control through the cooperation of the gas inlet and outlet pipeline valves of each raw material tank, the material inlet and outlet pipeline valves, the regulating valves for adjusting the flow rate, the flow meter, the automatic control device, etc., so that each material is automatically and evenly added to the mixer, and the discharge is completed synchronously;

[0081] The traditional process is: first draw material A, then draw material B..., or draw materials abc at the same time. Since the proportion of each material is not 1:1:1, the material with a smaller proportion will be drawn first, and then mixed after all the materials are drawn, resulting in low production efficiency. The above design of this application is the biggest difference from the traditional compounding process. No matter what the proportion of each material is, this application completes the materials at the same time, which is extremely efficient and reduces manual operations to improve product quality.

[0082] 7. Concentrate compounding equipment into standard containers to facilitate land and sea transportation;

[0083] 8. The container repackaging line adopts an automated production model to improve production efficiency and product quality.

[0084] In summary, this application has the following advantages and practicality:

[0085] 1. The equipment is simple, easy to load and transport, easy to install, easy to operate, and highly applicable;

[0086] 2. The efficiency is higher than the traditional compounding method;

[0087] 3. Suitable for field and outdoor;

[0088] 4. Suitable for use in places where electricity cannot be met;

[0089] 5. Suitable for mobile compounding on vehicles: the compounding system can be concentrated into a standard container for convenient land and sea transportation;

[0090] 6. The compounding production process is fully intelligent and adopts an automated production mode, which saves the labor input cost and manual errors of compounding production and improves production efficiency and product quality;

[0091] 7. It can reduce operational errors in manual production and thus improve product stability.

[0092] 8. On-site instant compounding can flexibly adjust the compounding formula according to demand to meet on-site needs, avoid the problem of untimely transportation to the site after remote compounding, and the problem that the products previously compounded and transported are difficult to meet current requirements, thereby reducing the labor intensity of the construction process.
