Description

Technical Field

[0001] This utility model relates to the field of horizontal mixer technology, specifically to a mixing arm for a horizontal mixer. Background Technology

[0002] The mixing arms of existing horizontal mixers are usually fixed in one piece with the connecting seat, resulting in a fixed installation angle for the mixing arms. However, a fixed-angle mixing arm cannot adapt to the flow characteristics of materials (such as viscosity, density differences, or particle size), and is prone to forming dead corners on the inner wall, bottom, or top of the mixing tank, leading to material stratification or incomplete mixing in some areas. Furthermore, a fixed-angle mixing arm can only move along a preset trajectory and cannot optimize the radial and axial flow of materials by adjusting the angle, resulting in a decrease in mixing uniformity.

[0003] Therefore, in order to solve the defects of uneven material mixing and many dead corners caused by the fixed angle of the mixing arm, it is necessary to propose a mixing arm for a horizontal mixer. Utility Model Content

[0004] The purpose of this invention is to provide a mixing arm for a horizontal mixer, which can be adapted to materials with different viscosities, densities and particle characteristics by precisely adjusting the angle of the mixing arm, thereby significantly improving the mixing uniformity.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mixing arm for a horizontal mixer includes a connecting seat and an arm body.

[0007] The surface of the connector is provided with a positioning plane;

[0008] The positioning plane is provided with insertion holes and positioning holes, and the positioning holes are distributed in a circular array with the insertion holes as the center.

[0009] The arm body is detachably connected by a plug rod and a plug hole;

[0010] The arm body is fixed to the positioning hole by a positioning plate.

[0011] Preferably, ten positioning holes are provided, and the included angle between two adjacent positioning holes is set to 36°.

[0012] Preferably, the connecting seat is fixed to the connecting plate of the stirring shaft via a mounting plane, and a reinforcing rib is provided at the intersection of the mounting plane and the connecting seat.

[0013] Preferably, the arm body may be equipped with a side scraper and blades for stirring materials.

[0014] Preferably, the side scraper is installed at both ends of the arm body through the second slot, and the blade is installed at the top of the arm body through the first slot.

[0015] Preferably, both the side scraper and the blade are provided with waist-shaped holes.

[0016] Preferably, the positioning plate is fixed to the positioning hole by countersunk screws.

[0017] Preferably, the front and rear ends of the first slot and the second slot are provided with through holes for the double-ended bolts to pass through.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. The mixing arm of this horizontal mixer uses a combination of a rod and a ring array of positioning holes to adjust the arm angle. It is suitable for high viscosity, granular or density-stratified materials, avoids material retention on the barrel wall, bottom and top, improves the uniformity of mixing, and the adjustable arm angle can change the mixing path, increase the shear force during mixing and shorten the mixing time.

[0020] 2. This horizontal mixer uses a mixing arm that increases the contact area between the arm and the material through side scrapers and blades, enhancing the flow of the material and evenly distributing the mixing force, reducing the stratification of the material. The waist-shaped holes prevent the material from accumulating on the blades and side scrapers, ensuring that the material can pass through smoothly and reducing residue. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figures 1-3 A horizontal mixer arm includes a connecting seat 1 and an arm body 2. The surface of the connecting seat 1 is provided with a positioning plane 11. The positioning plane 11 is provided with an insertion hole 111 and a positioning hole 112. The positioning holes 112 are arranged in a circular array with the insertion hole 111 as the center. The arm body 2 is detachably connected to the insertion hole 111 by an insertion rod 21. The arm body 2 is fixed to the positioning hole 112 by a positioning plate 25.

[0028] Among them, the connecting seat 1 is a key component connecting the stirring arm and the stirring shaft, which plays the role of supporting and fixing the arm body 2. It is usually made of high-strength alloy steel or wear-resistant material to ensure that the connecting seat 1 can withstand large loads and wear during long-term use.

[0029] Arm 2 is the main part of the mixing arm, which is responsible for directly contacting and mixing the material. It is usually made of wear-resistant and corrosion-resistant materials (such as stainless steel or special alloys) to cope with the wear and corrosion of the material on the arm 2.

[0030] The positioning plane 11 is obtained by milling on the surface of the connecting seat 1, providing a precise reference surface for the installation of the arm body 2, ensuring the alignment accuracy during installation. The machining accuracy requirement is high, and it usually needs to be precision milled or ground to ensure its flatness and smoothness.

[0031] The insertion hole 111 and the insertion rod 21 form a detachable connection, and the positioning holes 112 are arranged in a ring array with the insertion hole 111 as the center, allowing the arm body 2 to adjust the angle within a certain range to optimize the stirring effect. The inner wall of the insertion hole 111 and the surface of the insertion rod 21 are usually hardened (such as chrome plating or nitriding) to improve their wear resistance and service life.

[0032] The positioning hole 112 and the positioning plate 25 are engaged to fix the position of the arm 2 and prevent it from shifting or loosening during the stirring process.

[0033] Please see Figure 3 There are ten positioning holes 112, and the included angle between two adjacent positioning holes 112 is set to 36°.

[0034] The annular array distribution of the positioning holes 112 and the 36° included angle setting provide multiple fixed positions for the arm body 2, allowing it to flexibly adjust the angle to adapt to different stirring needs. The adjustable angle is limited to 36°, 72°, 108° and 144°.

[0035] Please see Figure 3 The connecting seat 1 is fixed to the connecting plate of the stirring shaft via the mounting plane 12, and a reinforcing rib 121 is provided at the junction of the mounting plane 12 and the connecting seat 1.

[0036] Among them, the mounting surface 12 is the contact surface between the connecting seat 1 and the stirring shaft connecting plate, ensuring a firm fixation between the two. The mounting surface is usually fixed to the stirring shaft connecting plate with bolts or pins to ensure the stability of the connecting seat 1 during the stirring process.

[0037] The reinforcing rib 121 is set at the intersection of the mounting plane 12 and the connecting seat 1 to enhance the structural strength of the connecting seat 1 and prevent it from deforming or breaking under stress. It adopts a triangular cross section to improve its bending and torsional resistance. The reinforcing rib 121 is usually made of the same material as the connecting seat 1 to ensure that its overall performance is consistent with that of the connecting seat 1.

[0038] Please see Figures 1-2 The arm body 2 can be equipped with a side scraper 3 and blades 4 for mixing materials.

[0039] Among them, the arm body 2 is the main part of the stirring arm, which can be equipped with side scrapers 3 and blades 4 and transmit stirring power. The arm body 2 adopts a rectangular cross section to ensure that it has sufficient strength and rigidity.

[0040] The side scraper 3 and blade 4 can increase the contact area between the arm 2 and the material, allowing more material to be directly stirred during the mixing process, enhancing the flow of the material. The larger contact area means that the material can be mixed faster and more evenly, reducing dead corners in the mixing container, preventing the material from stratifying or settling during the mixing process, and ensuring the uniformity of the material.

[0041] Please see Figures 1-2 The side scraper 3 is installed at both ends of the arm body 2 through the second slot 23, and the blade 4 is installed at the top of the arm body 2 through the first slot 22.

[0042] Among them, the side scrapers 3 installed at both ends of the arm body 2 and the blades 4 at the top of the arm body 2 can penetrate deep into the material and provide strong stirring force to ensure that the material flows and mixes fully in the container. The synergistic effect of the side scrapers 3 and the blades 4 can cover all areas of the mixing container, reduce stirring dead corners, and improve stirring efficiency and effect.

[0043] The slot installation method facilitates the disassembly and replacement of the side scraper 3 and blade 4. Different shapes and sizes of side scrapers 3 and blades 4 can be selected according to the properties of the material and the requirements of the mixing process to meet the mixing needs of different materials. It also makes it easy to clean the side scrapers 3 and blades 4 after mixing.

[0044] Please see Figures 1-2 Both the side scraper 3 and the blade 4 have waist-shaped holes 5.

[0045] The design of the waist-shaped hole 5 increases the contact area between the stirring end and the material, making it easier for the material to be cut and mixed during the stirring process, and helps to reduce the material residue during the stirring process. Due to the shape and position of the hole (set at the stirring end), the material flows more easily during the stirring process, reducing the adhesion of the material on the side scraper 3 and blade 4, thereby reducing the workload of cleaning and maintenance.

[0046] Please see Figure 1 The positioning plate 25 is fixed to the positioning hole 112 by countersunk screws 6.

[0047] Among them, M6 or M8 countersunk screws 6 can be used.

[0048] Please see Figure 4 Both the front and rear ends of the first slot 22 and the second slot 23 are provided with through holes 24 for the double-headed bolts 7 to pass through.

[0049] Among them, M8 or M10 double-ended bolts 7;

[0050] The diameter of the hole 24 should be slightly larger than the diameter of the double-ended bolt 7, but smaller than the diameter of the nut;

[0051] The side scraper 3 and the blade 4 are provided with mounting holes corresponding to the perforation 24.

[0052] When it is necessary to install the side scraper 3, insert the side scraper 3 into the second slot 23 with the end of the side scraper 3 having the waist-shaped hole 5 facing outward until the mounting hole of the side scraper 3 is aligned with the through hole 24. Pass the double-ended bolt 7 through the through hole 24 and the mounting hole, and finally tighten both ends of the double-ended bolt 7 with a nut.

[0053] When it is necessary to install blade 4, insert blade 4 into the first slot 22 with the end of blade 4 having the waist-shaped hole 5 facing outward until the mounting hole of blade 4 is aligned with the through hole 24. Pass the double-ended bolt 7 through the through hole 24 and the mounting hole, and finally tighten both ends of the double-ended bolt 7 with a nut.

[0054] Working principle: When adjusting the angle of the arm 2 of this horizontal mixer, use a screwdriver or wrench to remove the countersunk screws 6 on the positioning plate 25, hold the arm 2, and slowly rotate the arm 2 to the target angle (adjustable angles are 36°, 72°, 108° and 144°) with the insertion rod 21 as the axis, until the mounting hole on the positioning plate 25 is aligned with the positioning hole 112. Then insert the countersunk screws 6 into the positioning plate 25 and the positioning hole 112, and finally tighten the countersunk screws 6 with a screwdriver or wrench to complete the angle adjustment of the arm 2.
