Material tanks for pipe body production

Abstract

This utility model discloses a material tank for pipe body production, relating to the field of pipe body manufacturing. The material tank for pipe body production includes a cylindrical tank and a mixing unit. In this material tank, raw materials are conveyed to a distribution cone, which then enters a lower mixing tank. Under the action of a stirring blade, the raw materials undergo preliminary mixing in the lower mixing tank. This prevents the addition of raw materials from affecting the uniformity of mixing in the cylindrical tank, thus avoiding uneven mixing that could affect the quality of the product during pipe production. The raw materials, initially mixed in the lower mixing tank, enter the cylindrical tank where a stirrer performs a secondary mixing process, ensuring uniform mixing of the raw materials within the cylindrical tank.

Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, specifically to a material tank for pipe manufacturing. Background Technology

[0002] Pipe production equipment is a core piece of equipment in industrial manufacturing; it is used to process and shape pipes.

[0003] The main processing steps of plastic pipe production equipment include mixing, plasticizing, extrusion molding, cooling and shaping, drawing, cutting, and subsequent processing to complete pipe production. During pipe production, raw materials are fed into a mixing tank according to a certain ratio. The mixed raw materials are then transported to the extruder through a pipe and heated and melted at high temperature to form a viscous liquid. However, in the existing technology, when the raw materials are fed into the mixing tank, they are simultaneously fed into the extruder through a pipe, which affects the uniformity of the mixing. It is easy for the raw materials to enter the extruder before they are evenly mixed, affecting the product quality. Therefore, we propose a material tank for pipe production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a material tank for pipe production, which solves the problem that when raw materials are mixed in the mixing tank, they simultaneously enter the extruder through the pipeline, affecting the uniformity of the mixing and causing the raw materials to enter the extruder before being evenly mixed, thus affecting the quality of the product.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a material tank for pipe production, comprising a cylindrical tank body and a sealing cover installed on the cylindrical tank body, wherein the sealing cover is provided with a first inlet and a second inlet, the first inlet and the second inlet being connected to corresponding conveying pipes, and a mixing unit is installed in the cylindrical tank body;

[0006] The mixing unit includes a distributing cone, a lower mixing tank, and a stirring shaft. The lower mixing tank is fixedly connected to the bottom of the distributing cone. The outer peripheral wall of the stirring shaft is equipped with stirring blades and a stirrer. The stirring blades are located in the lower mixing tank and are used to initially mix the raw materials. The stirrer is located outside the distributing cone and inside the cylindrical tank.

[0007] Preferably, a lower conical tank is installed below the cylindrical tank, and the lower conical tank is installed at the feed inlet of the pipeline production equipment.

[0008] Preferably, a shaft seal assembly is installed on the cylindrical tank, a drive motor is installed on the shaft seal assembly, the stirring shaft is drivenly connected in the shaft seal assembly, and the top end of the stirring shaft is installed with the output end of the drive motor through the shaft seal assembly.

[0009] Preferably, a separator is fixedly connected to the material distribution cone, the separator dividing the material distribution cone into two parts, and the two parts are set corresponding to the first feed port and the second feed port.

[0010] Preferably, the area of ​​the dividing region of the material distribution cone is proportional to the ratio of the raw materials.

[0011] Preferably, the lower mixing tank has multiple sets of discharge troughs on its bottom outer peripheral wall.

[0012] Its beneficial effects are as follows:

[0013] The material tank used in the pipe production process uses a suction machine that, in conjunction with the first and second inlets, transports the raw materials into a distribution cone. The raw materials then enter the lower mixing tank through the distribution cone. Simultaneously, the rotating agitator shaft drives the stirring blades and agitator to rotate. Under the action of the stirring blades, the raw materials undergo preliminary mixing in the lower mixing tank. This prevents the addition of raw materials from affecting the uniformity of mixing in the cylindrical tank, which would otherwise result in uneven mixing and affect the product quality. The raw materials that have undergone preliminary mixing in the lower mixing tank then enter the cylindrical tank, where the agitator performs secondary mixing to ensure uniformity of mixing within the cylindrical tank.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0022] This utility model embodiment discloses a material tank for pipe body production, according to the appendix. Figure 1 As shown, it includes a cylindrical tank 1 and a sealing cover 2 installed on the cylindrical tank 1. The sealing cover 2 is provided with a first feed port 21 and a second feed port 22. The first feed port 21 and the second feed port 22 are connected to the corresponding conveying pipes. A mixing unit 4 is installed in the cylindrical tank 1.

[0023] The mixing unit 4 includes a distributing cone 41, a lower mixing tank 42, and a stirring shaft 44. The lower mixing tank 42 is fixedly connected to the bottom of the distributing cone 41. The outer peripheral wall of the stirring shaft 44 is equipped with a stirring blade 46 and a stirrer 45. The stirring blade 46 is located in the lower mixing tank 42 and is used to perform preliminary mixing of the raw materials. The stirrer 45 is located outside the distributing cone 41 and is located in the cylindrical tank 1.

[0024] Feed pipes are connected to the first feed port 21 and the second feed port 22. The feed pipes are connected to the suction machine. The suction machine works with the first feed port 21 and the second feed port 22 to transport the raw materials into the distribution cone 41.

[0025] The raw materials enter the lower mixing tank 42 through the distribution cone 41. At the same time, the stirring shaft 44 rotates, driving the stirring blades 46 and the agitator 45 to rotate. Under the action of the stirring blades 46, the raw materials are initially mixed in the lower mixing tank 42. This avoids affecting the uniformity of the raw material mixing in the cylindrical tank 1 when adding raw materials, which would lead to uneven mixing and affect the production quality of the product. The raw materials that have been initially mixed in the lower mixing tank 42 enter the cylindrical tank 1, where the agitator 45 performs a second stirring and mixing to ensure the uniformity of the raw material mixing in the cylindrical tank 1.

[0026] A lower conical tank 11 is installed below the cylindrical tank 1, and the lower conical tank 11 is installed at the feed inlet of the pipeline production equipment.

[0027] The raw materials that are mixed in the cylindrical tank 1 are in the lower conical tank 11 under the action of gravity, and are discharged into the pipeline production equipment through the lower conical tank 11.

[0028] The raw materials mixed in the cylindrical tank 1 are transported to the equipment by the pump body on the pipeline production equipment, and the production of the pipe body is carried out by plasticizing the raw materials, extrusion molding, cooling and shaping, drawing, cutting and subsequent processing. This is a mature existing technology and will not be described in this application.

[0029] According to the appendix Figure 2 As shown, a shaft seal assembly 3 is installed on the cylindrical tank 1, and a drive motor is installed on the shaft seal assembly 3. The stirring shaft 44 is connected in the shaft seal assembly 3, and the top end of the stirring shaft 44 is connected to the output end of the drive motor through the shaft seal assembly 3.

[0030] The stirring shaft 44 is driven by a drive motor to rotate. The rotation of the stirring shaft 44 causes the stirring blades 46 and the agitator 45 to rotate simultaneously. Under the action of the stirring blades 46, the raw materials are initially mixed in the lower mixing tank 42. The agitator 45 then performs secondary mixing on the raw materials in the cylindrical tank 1.

[0031] According to the appendix Figure 3 and Figure 4 As shown, a separator 43 is fixedly connected in the material distribution cone 41. The separator 43 divides the material distribution cone 41 into two parts, and the two parts are set to correspond to the first feed port 21 and the second feed port 22.

[0032] The raw materials entering through the first feed port 21 and the second feed port 22 enter the distribution cone 41 and are respectively located in the two regions formed by the separator seat 43 and the distribution cone 41.

[0033] By using a feed pipe for conveying, and by setting different separators 43, the material distribution cone 41 is divided into different parts corresponding to the number of feed pipes.

[0034] The area of ​​the dividing region of the dividing cone 41 is proportional to the ratio of the raw material.

[0035] In this embodiment, by setting the raw material ratio to 1:2, the area of ​​the distribution cone 41 set by the partition seat 43 is 1:2, and the size ratio of the feed inlet below it is 1:2, thereby controlling the proportion of raw materials entering the lower mixing tank 42.

[0036] Furthermore, the proportion of raw materials can be adjusted according to production needs to achieve suitable pipe production.

[0037] Raw materials enter the distribution cone 41 through the first feed port 21 and the second feed port 22. Under the action of the separator 43, the raw materials entering through the first feed port 21 and the second feed port 22 are separated into different regions in the distribution cone 41.

[0038] The raw materials in the distribution cone 41 enter the lower mixing tank 42 through the lower feed port, and are initially mixed by stirring under the action of the stirring blades 46;

[0039] Multiple discharge troughs 421 are provided on the outer peripheral wall of the bottom end of the lower mixing tank 42.

[0040] The raw materials are mixed in the lower mixing tank 42 by the stirring blade 46, and then the initially mixed raw materials are fed into the cylindrical tank 1 through the discharge chute 421.

[0041] Working principle: Feed pipes are connected to the first feed port 21 and the second feed port 22. The feed pipes are connected to the suction machine. The suction machine, together with the first feed port 21 and the second feed port 22, transports the raw material into the distribution cone 41. The raw material entering through the first feed port 21 and the second feed port 22 is separated into different areas in the distribution cone 41 by the action of the separator 43.

[0042] At this time, the raw materials in the distribution cone 41 enter the lower mixing tank 42 through the lower feed port. The drive motor drives the stirring shaft 44 to rotate. Under the rotation of the stirring shaft 44, the stirring blade 46 and the agitator 45 rotate simultaneously. Under the action of the stirring blade 46, the stirring is carried out for preliminary mixing. Then, the preliminary mixed raw materials are sent into the cylindrical tank 1 through the discharge chute 421.

[0043] The raw materials entering the cylindrical tank 1 are mixed a second time under the stirring of the agitator 45. Under the action of gravity, the raw materials are in the lower conical tank 11 and are discharged into the pipeline production equipment through the lower conical tank 11 for pipeline production.
