Description

Technical Field

[0001] This utility model relates to the technical field of MPP cable pipe production equipment, and in particular to an MPP cable pipe raw material mixing device. Background Technology

[0002] The production quality of MPP cable conduits depends on the uniformity of raw material mixing. Uneven mixing can lead to problems such as insufficient strength, easy cracking, and reduced corrosion resistance in the pipes. Existing MPP cable conduit raw material mixing devices have the following technical defects: Poor mixing uniformity and easy stratification: Traditional equipment often uses a single stirring paddle for mixing. Due to differences in density and particle size, the raw materials are prone to stratification. In particular, trace components such as modifiers are difficult to disperse evenly, which affects the overall performance of the pipe. Unfiltered raw material impurities affect quality: Raw materials may contain lumps, dust or foreign objects. Existing equipment lacks a pre-treatment filtration structure, and impurities enter subsequent processes with the raw materials, which can easily lead to blockage of the extrusion die or defects on the surface of the pipe. To address the aforementioned shortcomings, there is an urgent need for an MPP cable pipe raw material mixing device that can achieve uniform mixing, filter impurities, provide visual information on the status of the material, facilitate material discharge, and enable continuous operation. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an MPP cable pipe raw material mixing device. This device aims to overcome the defects of existing MPP cable pipe raw material mixing devices, such as uneven mixing, impurity residue, uncontrollable state, and inconvenient material discharge. It provides a highly efficient and practical mixing device that achieves uniform mixing and continuous processing of raw materials through segmented lifting and circulating mixing, raw material filtration, real-time observation, and convenient material discharge design, thereby ensuring raw material quality and improving production efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: MPP cable conduit raw material mixing device includes a receiving bucket, a conical material cylinder and a vertical frame located at its bottom. The lower end of the conical material cylinder is connected to a lower pipe body. The side wall of the lower pipe body is provided with a feeding structure. The bottom of the conical material cylinder is provided with an openable and closable discharge structure. The conical material cylinder and the lower pipe body are provided with a segmented material lifting mechanism. The bottom of the conical material cylinder is provided with a top cover, and the side of the top cover is hinged with a flip cover.

[0005] Preferably, the segmented material lifting mechanism includes an upper tube body located inside the conical cylinder. The upper and lower ends of the upper tube body are respectively fixed to the inner wall of the conical cylinder via an upper connecting frame and a lower connecting frame. An annular material inlet is provided at the bottom of the upper tube body and the conical cylinder. A spiral blade shaft is provided inside the upper tube body and the lower tube body. The upper end of the spiral blade shaft passes through the top cover and is connected to a driving device via a belt drive. The driving device is fixed to the outer wall of the conical cylinder.

[0006] Preferably, the feeding structure includes a feeding hopper disposed on the side wall of the lower pipe body, a feeding port disposed at the connection between the feeding hopper and the lower pipe body, and a detachable filter plate disposed on the inner wall of the feeding hopper, the filter plate being inclined.

[0007] Preferably, the discharge structure includes a discharge pipe inclinedly disposed on the bottom wall of the conical cylinder, and a valve plate is inserted into the side wall of the discharge pipe.

[0008] Preferably, the side wall of the conical cylinder is provided with an observation window.

[0009] Compared with the prior art, the beneficial effects of this utility model are: High mixing uniformity ensures pipe quality: The segmented material lifting mechanism realizes the "lifting-sprinkling-lifting" cycle of raw materials through the spiral blade shaft, breaking the layering problem of traditional single stirring, so that MPP resin and modifiers, stabilizers and other components are fully dispersed, avoiding performance defects of pipes caused by uneven raw materials from the source.

[0010] Raw material pretreatment filtration reduces defects: The inclined filter plate in the feed hopper can intercept lumps and foreign objects in the raw materials in advance, preventing impurities from entering the mixing chamber and subsequent processes, reducing the risk of extrusion die blockage, and reducing the surface defect rate of the pipe. At the same time, the detachable design makes it easy to clean and replace, and adapts to the filtration needs of different raw materials.

[0011] The mixing state is controllable in real time, reducing the scrap rate: The transparent observation window on the side wall of the conical cylinder allows operators to visually observe the degree of raw material mixing and adjust the mixing time in a timely manner to avoid scrap caused by insufficient mixing (uneven composition) or excessive mixing (raw material degradation).

[0012] Convenient and residue-free discharge, economical and efficient: The inclined discharge pipe, combined with the plug-in valve plate, allows the raw material to automatically slide into the receiving bucket after opening; discharge can be completed without disassembling parts, shortening the production interval and adapting to the needs of continuous production lines.

[0013] Simple structure, easy to maintain, and low operating threshold: The core hybrid mechanism has a high degree of integration, and the drive unit is connected by belt drive, resulting in a low failure rate; the flip-top design facilitates internal inspection and cleaning, and daily operation can be completed without professional personnel, reducing equipment maintenance costs and labor training costs.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1-3 The MPP cable pipe raw material mixing device includes a receiving bucket 5, a conical material cylinder 2 and a stand 1 located at its bottom. The lower end of the conical material cylinder 2 is connected to a lower pipe body 8. The side wall of the lower pipe body 8 is provided with a feeding structure. The bottom of the conical material cylinder 2 is provided with an openable and closable discharge structure. The inside is provided with a segmented material lifting mechanism. The top is provided with a top cover 10, and the top cover 10 is hinged to a flip cover 11 on the side.

[0019] Preparation before mixing: Place the receiving bucket 5 below the discharge pipe 6, select a filter plate 4 with an appropriate pore size according to the particle size of the raw material, and install it on the inner wall of the feed hopper 3; check whether the valve plate 13 is fully inserted into the discharge pipe 6 to ensure that the discharge port is closed; open the flip cover 11, check that there is no residual raw material inside the conical barrel 2, close the flip cover, and fasten the buckle.

[0020] Raw material feeding and filtration: MPP resin, modifier, stabilizer and other raw materials are poured into the feed hopper 3 in proportion. The raw materials slide along the inclined filter plate 4. Impurities (such as clumps and foreign objects) are intercepted on the filter plate. Qualified raw materials enter the lower pipe body 8 through the feed port.

[0021] Segmented cyclic mixing: Start the drive device 9, which drives the spiral blade shaft 12 to rotate at high speed via belt drive; the spiral blade shaft pushes the raw material in the lower tube 8 upward and discharges it through the upper outlet of the upper tube 14. Under the action of gravity, the raw material is evenly sprinkled to the bottom of the conical material cylinder 2; the sprinkled raw material re-enters the interior of the upper tube 14 through the annular material port between the upper tube 14 and the conical material cylinder 2, and is lifted again by the spiral blade shaft - this cycle repeats to achieve full mixing of the raw material; the operator can check the mixing status in real time through the observation window 7. When the raw material is uniform in color and there are no obvious lumps, the mixing is judged to be complete.

[0022] Convenient discharge and collection: After mixing, the valve plate 13 on the discharge pipe 6 is pulled out, and the mixed raw materials in the conical cylinder 2 automatically flow into the receiving bucket 5 below along the inclined discharge pipe 6; after discharge, the valve plate 13 is inserted to close the discharge pipe, and the mixing of the next batch of raw materials can begin, realizing continuous operation; if maintenance or cleaning is required, the inside of the conical cylinder 2 can be operated by opening the flip cover 11 without disassembling the overall structure.

[0023] The raw material is poured into the feed hopper 3, and the filter plate 4 filters the raw material. After filtration, the raw material enters the lower pipe body 8 through the feed port. The drive device 9 drives the spiral blade shaft 12 to rotate through the belt drive. The spiral blade shaft 12 lifts the raw material upward and discharges it from the upper end of the upper pipe body 14. It falls to the bottom of the conical material cylinder 2 and enters the upper pipe body 14 through the annular material port and is lifted again. By repeatedly lifting the raw material, the purpose of mixing the raw material is achieved. After the mixing is completed, the valve plate 13 is opened and the raw material is discharged from the discharge pipe 6 into the receiving bucket 5 for later use.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
