本实用新型是一种土建工程中砂子分选的复合分体式选砂机,涉及建筑材料技术领域。 The utility model relates to a composite split type sand separator for sand separation in civil engineering, which relates to the technical field of building materials. the
背景技术 Background technique
砂子是建筑工程中重要的工程材料。近年来,由于我国基本建设工程的快速发展,用于土木建筑工程中的合格砂源已渐近枯竭,现有砂源的砂子质量较差,特别是颗粒级配不好,细颗粒多而粗颗粒少,难以满足工程使用要求,需要进一步进行筛选处理。 Sand is an important engineering material in construction engineering. In recent years, due to the rapid development of my country's basic construction projects, the qualified sand sources used in civil construction projects have been gradually exhausted. The sand quality of the existing sand sources is poor, especially the particle gradation is not good, and there are many fine particles and coarse particles. There are few particles, it is difficult to meet the requirements of engineering use, and further screening is required. the
我国和世界上许多沙漠区域,近年来都已勘探出丰富的石油资源。石油开发离不开基本建设,而基本建设离不开混凝土。由于沙漠的特殊条件,目前混凝土用石子只能从沙漠外运入,巨大的运输费用使混凝土工程费用大幅上升。如能制造出一种选砂设备,从沙漠砂中能分选出可以满足工程施工要求的砂子,再利用选出的合格砂子制造混凝土用石子,可使工程建设费用大幅降低,带来巨大的经济效益。 In recent years, rich oil resources have been explored in many desert regions in my country and the world. Petroleum development is inseparable from infrastructure, and infrastructure is inseparable from concrete. Due to the special conditions of the desert, the stones used for concrete can only be transported from outside the desert at present, and the huge transportation cost has greatly increased the cost of concrete engineering. If a kind of sand selection equipment can be produced, the sand that can meet the requirements of engineering construction can be separated from desert sand, and then the qualified sand can be used to manufacture concrete stones, which can greatly reduce the construction cost and bring huge benefits. economic benefits. the
目前工程用砂很少进行分选处理,大多直接使用原砂。即使少量要求较高的工程对砂子进行分选,一般是采用水洗法或风选法,由于污水处理和环境污染等方面的限制,这些方法都不具备普遍推广应用的价值。同时,采用人工筛选,存在效率低、劳动强度大的问题,而传统的砂子分选机由于筛面的角度和密度等不适用于沙漠细颗粒砂多而粗颗粒少的问题。 At present, sand used in engineering is rarely sorted, and most of them use raw sand directly. Even if a small number of projects with high requirements are used to sort sand, water washing or winnowing is generally used. Due to the limitations of sewage treatment and environmental pollution, these methods do not have the value of general application. At the same time, manual screening has the problems of low efficiency and high labor intensity, while the traditional sand sorting machine is not suitable for the problem of deserts with more fine-grained sand and less coarse-grained sand due to the angle and density of the screen surface. the
CN101722151A公开了一种离心式砂粒分离装置和实现方法,该离心式分离方法是用离心式分离装置将待选砂料从下料装置到一级分离装置成均匀分散,后由二级分离装置以离心方式成伞状抛射到产品收集器,由收集器分离出待选砂料。但该方法和装置只能粗略的分选,精细度差,效率低。 CN101722151A discloses a centrifugal sand particle separation device and its implementation method. The centrifugal separation method is to use the centrifugal separation device to uniformly disperse the sand material to be selected from the feeding device to the primary separation device, and then use the secondary separation device to The centrifugal method throws it into the product collector in an umbrella shape, and the sand material to be selected is separated by the collector. But the method and device can only sort roughly, with poor fineness and low efficiency. the

本离心式砂粒分离装置主要用于把大于和小于某一控制粒径的砂粒分离开,使之满足工程应用要求。其待选砂料处理能力取决于所用电机的功率和转速,电机功率越大,转速越高,产量就越大。当电机功率在10千瓦以上、小时吞吐量大于30吨,分离效率在80%以上。 The centrifugal sand separation device is mainly used to separate sand particles larger and smaller than a certain control particle size to meet engineering application requirements. The processing capacity of the sand material to be selected depends on the power and speed of the motor used. The larger the motor power and the higher the speed, the greater the output. When the motor power is above 10 kW and the hourly throughput is above 30 tons, the separation efficiency is above 80%. the
本分体式选砂机自动化程度高,省时省力,结构简单,经久耐用,易于修复,处理量大,精细分选,可以分选出粒径大于0.6mm、0.6-0.3mm、0.3-0.15mm和小于0.15mm的砂子,分选效率可达70%以上。 This split type sand separator has a high degree of automation, saves time and effort, has a simple structure, is durable, is easy to repair, has a large processing capacity, and is finely sorted. And sand less than 0.15mm, the sorting efficiency can reach more than 70%. the
