技术领域 Technical field
本发明涉及一种利用高压式气力送砂的卧式抛丸处理机系统及处理方法,适用于对金属表面或钢管的管壁表面进行抛丸处理,尤其适用于对钢管内外壁同时进行抛丸处理,特别是针对管径大于 600mm 的钢管处理效果更佳,具体的说,本发明涉及一种可对钢管管壁表面进行处理的卧式抛丸处理机系统及送砂方法,属于钢管管壁处理技术领域。The invention relates to a horizontal shot blasting machine system and a processing method using high-pressure pneumatic air feeding, which is suitable for shot blasting on a metal surface or a pipe wall surface of a steel pipe, and is particularly suitable for simultaneously blasting a steel pipe inner and outer wall. Processing, especially for tube diameters greater than The treatment effect of the 600mm steel pipe is better. Specifically, the invention relates to a horizontal shot blasting machine system and a sand feeding method which can treat the surface of the steel pipe wall, and belongs to the technical field of steel pipe wall treatment.
背景技术 Background technique
钢管非常广泛地应用于供水领域,为了延长钢管的使用寿命,防腐处理非常重要。Steel pipes are widely used in the field of water supply. In order to extend the service life of steel pipes, anti-corrosion treatment is very important.
目前,比较先进的一种防腐措施就是在钢管内外壁进行涂塑处理,在涂塑之前需要对钢管的内外壁进行除锈,由于酸洗、磷化等除锈方式对环境污染严重,而且酸洗后的钢管壁比较光滑,降低了涂塑层在钢管壁的附着力,所以当前在对钢管内外壁进行涂塑之前,需要对钢管内外壁进行除锈处理时优选的除锈方式是抛丸除锈,一方面是因为抛丸除锈过程不会对环境造成污染,二是因为在对钢管内外壁抛丸除锈的过程中,可以增加钢管壁表面的粗糙度,从而增强涂塑层对钢管壁的附着力。At present, a more advanced anti-corrosion measure is to carry out plastic coating treatment on the inner and outer walls of the steel pipe. Before the plastic coating, the inner and outer walls of the steel pipe need to be derusted, and the rust removal method such as pickling and phosphating is serious to the environment and acid. The wall of the steel pipe after washing is relatively smooth, which reduces the adhesion of the plastic coating layer on the steel pipe wall. Therefore, the current descaling method for the inner and outer walls of the steel pipe is required to be blasted before the inner and outer walls of the steel pipe are coated. Rust removal, on the one hand, because the shot blasting process does not pollute the environment, and the second is because in the process of shot blasting on the inner and outer walls of the steel pipe, the surface roughness of the steel pipe wall can be increased, thereby enhancing the plastic coating layer. The adhesion of the steel pipe wall.
根据当前的抛丸除锈工艺,要对钢管的内外壁除锈,通常需要分别采用对钢管内、外壁单独除锈的抛丸机设备,分别对钢管的内、外壁进行抛丸除锈操作,内壁除锈过程一般需要 40 分钟,外壁除锈过程也需要 40 分钟,除锈时间长,效率低。 According to the current shot blasting process, it is necessary to rust the inner and outer walls of the steel pipe. It is usually necessary to separately use the shot blasting machine for the internal and external wall of the steel pipe to perform the shot blasting operation on the inner and outer walls of the steel pipe. The inner wall descaling process is generally required For 40 minutes, the outer wall descaling process takes 40 minutes, and the descaling time is long and the efficiency is low.
另外,虽然目前市场上对钢管的外壁进行抛丸除锈的技术比较成熟,但用于对钢管内壁抛丸除锈的技术尚不完善。 In addition, although the technology for shot blasting on the outer wall of steel pipes is relatively mature on the market, the technology for shot blasting on the inner wall of steel pipes is not perfect.
现有的钢管内壁抛丸处理设备,为了减小抛丸装置的尺寸以便适合处理小口径的钢管内壁,通常采用电机驱动液压站,液压站带动液压马达驱动抛丸头的动力传动模式,而且由于在抛丸过程中,钢管水平放置,为了将抛出的砂丸从钢管内部用强大的气流带出,就需要大功率的抽风除尘设备,所以现有的钢管内壁抛丸设备大都体积庞大需要占用较大的厂房空间,而且能耗高除锈效率低。尤其对于大口径的钢管,现有的卧式钢管内壁抛丸机在进行内壁抛丸除锈的过程中,当管径较大时管内的砂丸不易在抛丸过程中及时自动清理,影响抛丸处理效率和砂丸的循环使用。 The existing steel pipe inner wall shot blasting equipment, in order to reduce the size of the shot blasting device to be suitable for processing the inner wall of the small diameter steel pipe, usually adopts a motor driven hydraulic station, and the hydraulic station drives the hydraulic motor to drive the power blasting mode of the shot blasting head, and In the shot blasting process, the steel pipe is placed horizontally. In order to take out the thrown sand pill from the inside of the steel pipe with a strong airflow, a high-power exhaust dust removal device is required, so the existing inner wall shot blasting equipment of the steel pipe is mostly bulky and needs to be occupied. Large plant space, high energy consumption and low rust removal efficiency. Especially for large-diameter steel pipes, the existing horizontal steel pipe inner wall shot blasting machine in the process of shot blasting on the inner wall, when the pipe diameter is large, the sand pill in the pipe is not easy to be automatically cleaned in time during the shot blasting process, affecting the throwing Pill handling efficiency and recycling of sand pills.
目前用于对钢管内壁抛丸处理的抛丸处理机,在抛丸过程中需要将钢管水平放置,此时为了将抛出的砂丸从钢管内部用强大的气流带出,就需要大功率的抽风除尘设备,而且供砂系统大都是首先将砂丸提升到一定高度,然后砂丸依靠自身重力沿导砂管下滑到供砂皮带上, 再由皮带输送到抛丸头内部抛出,所以现有的钢管内壁抛丸设备大都体积庞大、结构复杂,需要占用较大的厂房空间,而且故障率高除锈效率低。尤其对于大口径的钢管,现有的卧式钢管内壁抛丸机在进行内壁抛丸除锈的过程中,管内的砂丸不易在抛丸过程中通过抽风设备及时自动清理,影响抛丸处理效率和砂丸的循环使用。At present, the shot blasting machine used for shot blasting on the inner wall of steel pipe needs to place the steel pipe horizontally during the shot blasting process. In this case, in order to take the thrown sand ball out from the inside of the steel pipe with a strong air flow, high power is required. Exhaust dust removal equipment, and most of the sand supply system first raises the sand pill to a certain height, and then the sand pill slides along the sand guide pipe to the sand supply belt by its own gravity. Then, the belt is conveyed to the inside of the shot blasting head. Therefore, the existing inner wall blasting equipment of the steel pipe is bulky and complicated in structure, and needs to occupy a large workshop space, and the failure rate is high and the rust removal efficiency is low. Especially for large-diameter steel pipes, the existing horizontal steel pipe inner wall shot blasting machine in the process of shot blasting on the inner wall, the sand pill in the pipe is not easy to be automatically cleaned by the exhausting equipment in the shot blasting process, which affects the efficiency of shot blasting. And the recycling of sand pills.

In addition, the steel pipe which needs to be rusted is continuously rotated during the shot blasting process, thereby resulting in low shot blasting efficiency and rust removing effect. Poor question. The shot blasting structure is shown in the figure 2 As shown, the shot blasting head rotates on the inner wall of the steel pipe along the horizontal plane of the steel pipe axis, and the rust removing sand pill is fed from the top of the shot blasting head into the horizontally placed shot blasting head through the belt sanding device, and the sand pill is under the action of its own gravity. The pelletizing machine and the splitting hole are dispersed to the shot blasting blade, and the inner wall of the steel pipe is thrown from the side of the blasting head by the blade at high speed, thereby achieving the purpose of removing the rust on the inner wall of the steel pipe.
