Description

Technical Field

[0001] This utility model relates to the technical field of solid-liquid mixing equipment, and more specifically, to a solid-liquid rapid mixing device. Background Technology

[0002] In numerous industrial sectors such as chemical, food, and construction, solid-liquid mixing units are key equipment for achieving efficient material mixing. Currently, most solid-liquid mixing operations rely on large-scale mixing equipment with fixed configuration sites. While these devices offer advantages such as high mixing efficiency and stable production capacity, they suffer from limited application scenarios. Because the equipment cannot be moved, materials must be transported long distances to fixed sites for mixing in remote construction sites or emergency operations, leading to significantly increased transportation costs and difficulties in ensuring timely operation.

[0003] To address the limitations of fixed-location sites, mobile solid-liquid mixing units have emerged. However, existing mobile solid-liquid mixing units have significant shortcomings when dealing with complex outdoor operating environments. Especially in humid environments such as rainy days, their feed inlets generally lack effective waterproofing designs, allowing rainwater to easily enter the unit. Once inside, rainwater dilutes the materials being mixed, altering the original material ratio and causing a decline in the quality of the mixed product, failing to meet process standards. Furthermore, rainwater can cause short circuits in electrical equipment, damaging core components such as motors and sensors, leading to equipment malfunctions and downtime, severely impacting work progress and increasing maintenance costs. In addition, humid environments easily cause rust and corrosion of internal metal components, shortening the equipment's lifespan and reducing its operational stability and reliability.

[0004] In summary, existing solid-liquid mixing devices are insufficient to meet diverse operational needs, and there is an urgent need to develop a solid-liquid mixing device with good waterproof performance to improve the adaptability and reliability of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a solid-liquid rapid mixing device, which can store solid materials through a transport tank. In humid environments such as rainy days, the sealed structure of the transport tank can realize the closed storage and transportation of materials, avoiding rainwater seeping into the device through the feed inlet due to outdoor material dumping. The material can be poured into the transport tank in advance, and the transport tank can be quickly installed on the auxiliary hopper, so that efficient mixing can be completed without exposing the material to the open air.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Example

[0031] Please refer to Figure 1-6 The present invention provides a solid-liquid rapid mixing device, including a rapid mixing unit and a feeding unit connected to the rapid mixing unit. The feeding unit includes a transport tank 200 and a feed hopper 300. The transport tank 200 and the feed hopper 300 are connected through a valve pipe assembly. The feed hopper 300 is connected to the rapid mixing unit. The transport tank 200 is provided with a first cover plate 210.

[0032] The device consists of a rapid mixing unit and a feeding unit. The conveying tank 200 of the feeding unit is connected to the auxiliary hopper 300 via a valve pipe assembly. The first cover plate 210 on the conveying tank 200 can achieve a seal. Solid materials are stored in the conveying tank 200, flow into the auxiliary hopper 300 through the valve pipe assembly, and then enter the rapid mixing unit. The first cover plate 210 can prevent rainwater from entering the conveying tank 200, forming a closed material transport channel. This allows solid materials to enter the rapid mixing unit from the conveying tank 200 in a sealed state, preventing rainwater from seeping into the device through the feed inlet during outdoor material dumping, avoiding dilution of the material by rainwater, ensuring accurate material proportioning, and improving the quality of the mixed product. It also prevents rainwater from causing short circuits in electrical equipment, reducing the risk of equipment failure, reducing maintenance costs, reducing rust and corrosion of internal metal parts, and extending the service life of the equipment.

[0033] When it is not raining, the device can be unloaded from the transport tank 200 and the auxiliary hopper 300 can be used for bag-breaking and feeding operations, which is the conventional outdoor material mixing operation mode. Alternatively, the transport tank 200 can remain unloaded, and only the first cover plate 210 can be opened for bag-breaking and feeding operations. When it rains, the transport tank 200 can be moved indoors or to a dry area, the material can be poured into the transport tank 200 after breaking the bags, the first cover plate 210 can be closed, and the transport tank 200 can be moved onto the auxiliary hopper 300 for use as a material supply device. This allows the device to perform material mixing under closed conditions, unaffected by external factors, and maintains the dryness of the mixed materials.

[0034] Furthermore, the valve tube assembly includes a fixed cylinder 410 and several fixed plates 420. The several fixed plates 420 are circumferentially spaced on the end face of the fixed cylinder 410. One end of the fixed cylinder 410 is connected to the transport tank 200 and the other end is connected to the auxiliary hopper 300. The fixed plates 420 are fixedly connected to the transport tank 200. A one-way valve is provided inside the fixed cylinder 410.

[0035] The fixing plate 420 is used to fix the transport tank 200 and the fixing cylinder 410, and to fix the connection between the transport tank 200 and the auxiliary hopper 300. The one-way valve only allows the material to flow from the transport tank 200 to the auxiliary hopper 300, preventing reverse flow and avoiding material backflow that could cause an imbalance in the mixing ratio, thus improving mixing efficiency. At the same time, it prevents external dust, rainwater, etc. from entering the device through the valve pipe assembly, further improving the equipment's waterproof and pollution-proof capabilities.

[0036] Furthermore, the transport tank 200 includes a tank body 230, a filter screen 240, a bag breaker 250, and a support assembly. The support assembly is fixedly connected to the bottom of the tank body 230, the filter screen 240 is fixed inside the tank body 230, and the bag breaker 250 is fixed on the filter screen 240.

[0037] Material is placed into tank 230, bag breaker 250 punctures the bag, and material falls into the bottom of tank 230 through filter screen 240. The filter screen 240 breaks up lumpy material into powder and flows in, making the mixing more thorough, improving the automation of material processing, reducing manual bag breaking operations, and preventing problems such as handling difficulties and material loss caused by manual bag breaking. After filtration, impurities are prevented from entering, and material is prevented from entering the device in clumps, causing uneven mixing or blockage.

[0038] Furthermore, the support assembly includes several legs 260, which are circumferentially fixed to the bottom of the tank body 230 to ensure that the transport tank 200 will not tilt or collapse during use, thereby improving the safety and stability of the equipment operation.

[0039] Furthermore, several support legs 260 are detachably connected to the auxiliary hopper 300.

[0040] It is worth noting that the support leg 260 has a groove at its bottom, and the top of the hopper 300 has a protrusion that matches the groove. The support leg 260 can be inserted into the hopper 300 through the groove and the protrusion, thus achieving a detachable connection. This facilitates the movement and installation of the equipment in different operating scenarios, improving the equipment's flexibility and adaptability. It is especially suitable for scenarios requiring movement, such as remote construction sites and emergency operations. At the same time, when it is not raining, the transport tank 200 can be removed, and only the hopper 300 can be used for bag-breaking and feeding operations. When it rains, it can be quickly inserted to complete the fixation. The plug-in fixation method not only facilitates disassembly and installation, but also reduces the use of screws, speeds up the disassembly and installation process, and reduces the lifespan problems caused by rusting of screws over time, thus reducing the incidence of equipment failure.

[0041] Furthermore, the bag-breaking device 250 includes a first bag-breaking cone plate and a second bag-breaking cone plate, which are intersected and coaxially arranged.

[0042] The first and second bag-breaking cones form a sharp structure. When the material falls and impacts the bag breaker 250, the bag can be easily torn. At the same time, this structural design can cut the bag in a cross shape from the center opening, which can quickly increase the opening area of ​​the bag, allowing the material to be discharged quickly, improving the bag-breaking efficiency, ensuring that the material enters the transport tank 200 quickly, reducing manual intervention, and improving the working efficiency of the entire mixing device.

[0043] Furthermore, the transport tank 200 is equipped with several lifting lugs 220. By hooking the lugs with lifting equipment, the transport tank 200 can be lifted and moved, making it convenient for users to disassemble and install the transport tank 200 from the auxiliary hopper 300, reducing the difficulty of handling and improving the efficiency of equipment installation and transfer.

[0044] Furthermore, the bottom of the tank 230 is conical, and a discharge port is provided at the bottom of the tank 230, which is connected to the fixed cylinder 410.

[0045] The conical structure allows the material to be concentrated at the discharge port under the action of gravity and flow smoothly into the fixed cylinder 410, promoting the smooth flow of material from the bottom of the tank 230, avoiding material residue in the tank 230, ensuring complete discharge of material, improving material utilization, reducing waste, and preventing material residue from causing deterioration or blockage, which would affect the normal operation of the equipment.

[0046] Furthermore, the hopper 300 is provided with a second cover plate 320, which has an inlet that is connected to the fixed cylinder 410.

[0047] The second cover plate 320 further seals the auxiliary hopper 300 to prevent rainwater from entering. It works in conjunction with the first cover plate 210 of the transport tank 200 to form a double seal, preventing rainwater from entering the device from the auxiliary hopper 300 and enhancing the waterproof performance of the feeding unit. It also prevents materials from spilling out after flowing into the auxiliary hopper 300, thus preventing waste. Since the material is in powder form, it also prevents the generation of dust.

[0048] It is worth noting that both the first cover plate 210 and the second cover plate 320 are equipped with snap-fit ​​mechanisms to enable detachable connection.

[0049] Furthermore, the second cover plate 320 is provided with an annular sealing cover 310, which is coaxially arranged with the feed inlet and connected to the fixed cylinder 410.

[0050] By setting an annular sealing cover 310 to form a tight sealing structure, the sealing performance between the fixed cylinder 410 and the auxiliary hopper 300 is enhanced, preventing material leakage and rainwater infiltration, further improving the sealing performance of the feeding unit, ensuring that the entire feeding process is completely closed, avoiding the influence of the external environment on material mixing, and improving the reliability and stability of the equipment.

[0051] It is worth noting that the auxiliary hopper 300 is also equipped with a filter screen 240 and a bag breaker 250, and the bottom is also conical with a discharge port, which enables it to independently perform bag breaking and material conveying operations when it is not raining.

[0052] It should also be noted that the rapid mixing unit includes a housing 100, a conveying mechanism and a mixing mechanism, which are located inside the housing 100 and are connected to each other.

[0053] The material conveying mechanism includes a feeding hopper 110, a spiral feed column 120, and a cylinder 130. The feeding hopper 110 is fixed at the top inside the housing 100 and is connected to the discharge port of the auxiliary hopper 300. The bottom of the feeding hopper 110 is connected to the spiral feed column 120 through a flange, and the spiral feed column 120 is connected to the cylinder 130.

[0054] The mixing mechanism includes a mixing tank 140, a single-stage emulsifying pump 150, a centrifugal pump 180, and a filter 190. The mixing tank 140 is fixed to the bottom of the housing 100 and is connected to the cylinder 130. The bottom side of the mixing tank 140 away from the cylinder 130 is connected to the single-stage emulsifying pump 150. The top of the mixing tank 140 is connected to the centrifugal pump 180. An electromagnetic flowmeter 170 is installed between the mixing tank 140 and the centrifugal pump 180. The centrifugal pump 180 is connected to the filter 190 through an electric two-way ball valve 191.

[0055] The single-stage emulsifying pump 150 is also connected to a three-phase asynchronous motor 160, and a discharge pipe is connected to the top of the single-stage emulsifying pump 150, which is connected to another electric two-way ball valve 191.

[0056] In use, on sunny days, unload the transport tank 200 and add the material bag directly through the inlet of the second cover plate 320 of the auxiliary hopper 300. The bag breaker 250 in the auxiliary hopper 300 will cut the material bag, and the filter screen 240 will simultaneously filter out lumpy impurities, ensuring that the material falls into the bottom of the auxiliary hopper 300 in powder form. Open the bottom outlet of the auxiliary hopper 300, and the material enters the feed funnel 110 of the rapid mixing unit. Then, it is uniformly conveyed to the mixing box 140 through the spiral feed column 120. Liquid material is injected into the mixing box 140, and the single-stage emulsification pump 150 is started by the three-phase asynchronous motor 160. The high-speed rotation generates shearing force to initially mix the solid and liquid materials. The centrifugal pump 180 runs synchronously and draws the mixture from the top of the mixing box 140. After being measured by the electromagnetic flow meter 170, it is sent to the filter 190 through the electric two-way ball valve 191. The filtered material then flows back to the mixing box 140 to form a circulating mixture.

[0057] During rainy weather, the material bags are placed into the transport tank 200 in a dry area. The bag breaker 250 automatically breaks the bags, the filter screen 240 filters the material, and the bottom of the conical tank 230 concentrates the material to the discharge port. The one-way valve is closed to store the material in the transport tank 200, and the first cover plate 210 seals the tank 230. The transport tank 200 is hoisted above the auxiliary hopper 300 using the lifting lugs 220. The bottom groove of the support leg 260 is inserted and fixed to the top protrusion of the auxiliary hopper 300. The fixing cylinder 410 of the valve pipe assembly is connected to the discharge port of the transport tank 200 and the inlet of the auxiliary hopper 300. The one-way valve ensures unidirectional flow of the material. When the one-way valve of the transport tank 200 is opened, the material enters the auxiliary hopper 300 through the fixing cylinder 410 and flows into the rapid mixing unit for material mixing. The entire process is a closed transport to prevent rainwater from seeping in.

[0058] The first cover plate 210 of the transport tank 200, the second cover plate 320 of the auxiliary hopper 300, the annular sealing cover 310, and the one-way valve of the valve pipe assembly together form a multi-layer waterproof structure, which can ensure that the material transport channel is completely sealed even in rainy weather, and prevent rainwater from seeping in and affecting the mixing quality.

[0059] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
