Description

Technical Field

[0001] This utility model relates to the technical field of substrate feeding devices, and more specifically, to a substrate mixing and pumping feeding device. Background Technology

[0002] Substrate mixing and pumping feeding devices are key equipment for mixing and conveying substrates in the fields of construction, chemical industry, and building materials. They are widely used in concrete pouring, paint spraying, mortar conveying and other scenarios. The mixing and pumping feeding device can realize the mixing operation of materials through its own mixing mechanism. After the mixing is completed, its own pumping device can transport the mixed materials to the corresponding application site, achieving the effect of mixing and pumping in one.

[0003] Existing substrate mixing and pumping feeding devices on the market still have some shortcomings in use. While they employ multiple mixing blades to achieve thorough mixing, the pumping system is often directly connected to the mixing chamber, lacking effective pretreatment structures such as filtration. If undissolved hard lumps remain in the mixed substrate, these lumps can easily clog the pumping pipes during material transport, affecting feeding efficiency, requiring shutdown for cleaning, and increasing maintenance costs. Therefore, we propose a substrate mixing and pumping feeding device. Utility Model Content

[0004] The purpose of this invention is to provide a substrate mixing and pumping feeding device to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A substrate mixing and pumping feeding device includes a mixing tank. A feed hopper is fixedly installed on the top of the mixing tank. A crushing component for crushing the material at the discharge end of the feed hopper is also provided inside the top of the mixing tank. A mixing motor is fixedly installed at the center of the top surface of the mixing tank. The output shaft of the mixing motor extends through the mixing tank and is fixedly installed with a mixing shaft. Mixing blades are fixedly installed on the mixing shaft. A discharge pipe is fixedly installed at the bottom of the mixing tank. A discharge valve is fixedly installed on the discharge pipe. An expansion mask is fixedly installed at the discharge end of the discharge pipe. An inner manifold is fixedly installed on the bottom inner wall of the expansion mask. A filter screen is detachably installed on the bottom surface of the inner manifold. An inlet hose is flanged to the bottom surface of the expansion mask. The other end of the inlet hose is connected to a feeding pump.

[0006] Preferably, liquid pipes are fixedly installed on both the top plate and the side top plate of the mixing tank, and the inner diameter of the liquid pipes is between 3cm and 5cm.

[0007] Preferably, the outer end face of the stirring blade slides against the inner wall of the stirring tank, and the bottom of the stirring tank is funnel-shaped.

[0008] Preferably, the filter screen and the inner manifold are detachably connected by a plurality of fastening screws, and the filter screen and the inner manifold are inserted into each other; This setting facilitates the installation, removal, and cleaning of the filter screen.

[0009] Preferably, the inner wall of the inner manifold is provided with a manifold inclined surface, which is inclined inward at 15 degrees to 30 degrees toward the center of the inner manifold. This feature facilitates the guidance of materials into the inlet hose.

[0010] Preferably, an upper flange is fixedly installed at the bottom of the inner manifold, and a lower flange is fixedly installed at the top of the inlet hose. The upper flange and the lower flange are fixedly connected by multiple fastening bolts.

[0011] Preferably, a sealing ring is provided between the upper flange and the lower flange, and an external delivery pipe is fixedly installed at the discharge end of the feed pump.

[0012] Preferably, the crushing component includes two symmetrical rotating shafts on the left and right, with their ends rotatably connected to the inner walls of the front and rear side plates of the mixing tank, respectively. Crushing rollers are fixedly installed on the rotating shafts. Gears are fixedly installed on the ends of the two rotating shafts that rotatably extend to the end of the mixing tank. The two gears mesh with each other. A drive motor is coaxially arranged at the other end of one of the rotating shafts that extends to the outside of the mixing tank. This setting can pre-crush the incoming materials.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves pre-crushing treatment of materials at the discharge end of the feed hopper by setting a crushing component consisting of a rotating shaft, crushing roller, gear and drive motor at the top of the mixing tank. It breaks up agglomerated materials into particles that meet the conveying requirements, avoids large pieces of material from directly entering the subsequent conveying process, and achieves the effect of reducing the formation of hard material lumps and reducing the risk of pump blockage from the source.

[0014] 2. This utility model achieves filtration of the stirred material by detachably installing a filter screen on the bottom surface of the inner manifold of the inner wall of the expansion mask. It can effectively intercept residual hard lumps that are not completely broken up during the stirring process, preventing hard lumps from entering the inlet hose and feed pump with the material. This further avoids pumping pipe blockage, ensures stable material supply efficiency, and reduces downtime cleaning and maintenance costs.

[0015] 3. This utility model achieves efficient material guidance by setting the inner wall of the inner manifold to an inwardly inclined confluence slope, combined with the funnel-shaped structure at the bottom of the mixing tank, guiding the material to smoothly converge to the inlet hose; at the same time, the filter screen and the inner manifold are detachably connected by fastening screws, which facilitates regular disassembly, cleaning or replacement of the screen, thereby improving the smoothness of material conveying, reducing the difficulty of device maintenance and extending the service life of the equipment.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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] Please see Figures 1-3 This utility model provides a technical solution: a substrate mixing pump feeding device, including a mixing tank 1, with a feed hopper 10 fixedly installed on the top of the mixing tank 1, so that the substrate to be mixed can smoothly enter the mixing tank 1 through the feed hopper 10, providing a stable material input channel for subsequent mixing operations and ensuring normal feeding of the device.

[0019] like Figure 1 and Figure 3As shown, a crushing assembly 4 for crushing the material at the discharge end of the feed hopper 10 is also provided at the top of the interior of the mixing tank 1. The crushing assembly 4 includes two symmetrical rotating shafts 40, each rotatably connected to the inner walls of the front and rear side plates of the mixing tank 1. Crushing rollers 41 are fixedly mounted on the rotating shafts 40. Gears 42 are fixedly mounted on one end of each rotating shaft 40 that rotatably protrudes from the outside of the mixing tank 1. The two gears 42 mesh with each other. A drive motor 43 is coaxially mounted on the other end of one of the rotating shafts 40 that protrudes from the outside of the mixing tank 1. The drive motor 43 is fixedly mounted on the outer surface of the mixing tank 1. By driving the two crushing rollers 41 to rotate through the drive motor 43, the incoming material can be pre-crushed, breaking up lumps of material, preventing large pieces of material from affecting subsequent mixing and pumping, and reducing the risk of blockage.

[0020] like Figure 1 As shown, a stirring motor 3 is fixedly installed at the center of the top surface of the mixing tank 1. The output shaft of the stirring motor 3 extends through the mixing tank 1 and is fixedly installed with a stirring shaft 30. A stirring blade 31 is fixedly installed on the stirring shaft 30. The outer end face of the stirring blade 31 slides against the inner wall of the mixing tank 1. When the stirring motor 3 drives the stirring shaft 30 and the stirring blade 31 to rotate, the material in the mixing tank 1 can be fully stirred. At the same time, the outer end of the stirring blade 31 that is in contact with the inner wall can scrape off the residual material on the tank wall, thereby improving the uniformity of stirring and the utilization rate of materials.

[0021] like Figure 1 As shown, a discharge pipe 12 is fixedly installed at the bottom of the mixing tank 1, and a discharge valve 121 is fixedly installed on the discharge pipe 12. The bottom of the mixing tank 1 is funnel-shaped, so that the mixed material can enter the discharge pipe 12 under the guidance of the funnel-shaped bottom of the tank. At the same time, the discharge start and stop and the discharge speed can be flexibly controlled by the discharge valve 121 to adapt to different material supply needs.

[0022] like Figure 1 and Figure 2 As shown, an expanding mask 13 is fixedly installed at the discharge end of the discharge pipe 12. An inner confluence cylinder 14 is fixedly installed on the bottom of the inner wall of the expanding mask 13. A confluence slope 141 is provided on the inner wall of the inner confluence cylinder 14. The confluence slope 141 is set inward at an angle of 15 to 30 degrees toward the center of the inner confluence cylinder 14, so that the material flowing out of the discharge pipe 12 can be smoothly gathered below the inner confluence cylinder 14 under the guidance of the expanding mask 13 and the confluence slope 141, avoiding material scattering and improving material conveying efficiency.

[0023] like Figure 1 and Figure 2As shown, a filter screen 22 is detachably installed on the bottom surface of the inner manifold 14, and an inlet hose 20 is connected to the bottom surface of the expansion mask 13 via a flange. The other end of the inlet hose 20 is connected to the feed pump 2. The filter screen 22 and the inner manifold 14 are detachably connected by multiple fastening screws. The filter screen 22 and the inner manifold 14 are interlocked, allowing the stirred material to pass through the filter screen 22 for filtration, intercepting undissolved hard lumps. At the same time, it is convenient to disassemble the filter screen 22 for cleaning or replacement, ensuring filtration effect and ease of device maintenance.

[0024] like Figure 1 As shown, liquid pipes 11 are fixedly installed on the top plate and the side top plate of the mixing tank 1. The inner diameter of the liquid pipes 11 is between 3cm and 5cm, so that liquid materials such as water and additives can be accurately added into the mixing tank 1 through the liquid pipes 11 to mix with the substrate. At the same time, the appropriate inner diameter can ensure the liquid material conveying speed and adapt to the substrate mixing ratio requirements.

[0025] like Figure 1 and Figure 2 As shown, an upper flange 15 is fixedly installed at the bottom of the inner manifold 14, and a lower flange 21 is fixedly installed at the top of the inlet hose 20. The upper flange 15 and the lower flange 21 are fixedly connected by multiple fastening bolts, so that the inlet hose 20 is firmly connected to the expansion mask 13.

[0026] In this embodiment, a sealing ring is provided between the upper flange 15 and the lower flange 21. The sealing ring can prevent material leakage and ensure the sealing and stability of the conveying process. An external delivery pipe 23 is fixedly installed at the discharge end of the feed pump 2, so that the filtered material can be transported to the designated application site through the external delivery pipe 23 under the action of the feed pump 2, realizing efficient pumping of materials and meeting the actual construction material supply needs.

[0027] Finally, it should be noted that the drive motor 43, stirring motor 3, feeding pump 2, corresponding control system and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and matching controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0028] When using the substrate mixing pump feeding device of this utility model, first start the drive motor 43 of the crushing component 4 to drive the rotating shaft 40 and the crushing roller 41 to rotate, pour the substrate to be mixed from the feed hopper 10, and the substrate enters the mixing tank 1 after being pre-crushed by the two crushing rollers 41; if liquid needs to be added, water or additives are injected through the two liquid pipes 11 on the mixing tank 1. Next, start the stirring motor 3. Its output shaft drives the stirring shaft 30 and stirring blades 31 to rotate. The stirring blades 31, which are in contact with the inner wall of the mixing tank 1, fully stir the material and scrape off the residue on the tank wall. After stirring is completed, open the discharge valve 121 on the discharge pipe 12. The material enters the discharge pipe 12 under the guidance of the funnel-shaped tank bottom, and then converges through the expansion mask 13 and the converging inclined surface 141 of the inner converging cylinder 14. The material is filtered through the filter screen 22 to remove residual hard lumps. Finally, start the feed pump 2. The filtered material enters the feed pump 2 through the inlet hose 20 and is transported to the designated location through the external delivery pipe 23 under the action of the feed pump 2. If it is necessary to stop the feeding, simply close the discharge valve 121. The filter screen 22 can be disassembled and cleaned regularly to ensure the stable operation of the device.
