Изобретение относитс к гвдротракспорту , а именно к устройствам дл гидротранспорта сыпучих матери лов, и может быть использовано в пи щевой промышленности при гидравлическом транспортировании сырь .The invention relates to railway transport, namely to devices for hydrotransport of bulk materials, and can be used in the food industry in the hydraulic transportation of raw materials.

Известна установка дл гидротранспорта сыпучих продуктов, содержаща насос, приемную воронку и устройство дл предотвращени закупорки трубопроводов после остановки насоса, в котором дл предотвращени закупоривани трубопровода одновременно с транспортируемым материалом в трубопровод ввод тс эластичные шары, заполненные сжатым воздухом l.A known installation for hydrotransport of bulk products, comprising a pump, a receiving funnel and a device for preventing pipeline clogging after stopping the pump, in which elastic balls filled with compressed air l are introduced into the pipeline simultaneously with the material being transported to prevent the pipeline from clogging.

Однако данна установка сложна и требует дополнительных затрат на изготовлеииё эластичных шаров, создание устройства дл ввода шаров в трубопровод , отделение шаров от про дукта и возврата их на поворотное использование.However, this installation is complex and requires additional costs for the manufacture of elastic balls, the creation of a device for inserting balls into the pipeline, separating the balls from the product and returning them to the rotary use.

Известна также установка дл гидротранспорта сыпучих материалов, содер-. жаща загрузочную ескость, сообщенную с промывочной емкостью, водоотделитель и грузоприемное устройство, соединенные транспортным трубопроводом через насос с загрузочной емкостью 2.Also known installation for hydrotransport bulk materials, contains -. Zazhchas loading boot, communicated with the flushing tank, water separator and load receptor device connected by a transport pipeline through the pump with the loading tank 2.

Claims

The disadvantage of this installation is that it ensures reliable operation only in continuous mode, as with frequent shutdowns, pipelines are clogged. The use of the installation in automatic lines, where the basic condition is to operate in a periodic mode, requiring frequent line stops, leads to clogging of pipelines. To prevent clogging of pipes, you must first pump the entire product out of the supply tank, and then pump water into it, pump it until the pipelines are completely empty of the product, which disrupts the normal rhythm of the line and leads to additional labor costs. The purpose of the invention is to ensure reliable operation of the plant in batch mode. To achieve this goal, the installation is equipped with an automatic valve installed on the transport pipeline and connecting the load tank with the pump and the flushing tank, while the load receptor is equipped with a sensor connected to the automatic valve. In the drawing, schematically, the image we offer installation. The installation consists of a discharge tank 1, where the product is mixed with water. The loading tank through the automatic valve 2 and the suction section 3 of the transport pipeline is connected to the washing tank 4 and the pump 5, which, in turn, the delivery section 6 of the transport pipeline is connected to the water separator 7 installed at the place of consumption of the product. Behind the water separator 7 there is a metering station, which includes a feeder 8 and a lifting device 9, equipped with a contactless sensor 10, which records the required weight of the product in the load receptor 9 and sends a command to the automatic loianaH 2. The installation works in the following way. and the water is supplied to the loading tank 1, from where the pump 5 through the automatic valve 2 and suction 3 and the discharge 6 transport pipeline sections are pumped to the water separator 7, where the separation of the product produced from the water. From the water separator 7, the product enters the feeder 8 of the dosing station, and from there the load receptor 4. From capacity 4 for WATER. After the water has displaced the entire product from the transport pipeline, the pump 5 stops. The advantage of the invention in comparison with the prototype is to ensure reliable operation in batch mode. This mode does not block the transport pipeline, which makes it possible to create automatic complexes with discrete metering stations. The invention The installation for the hydraulic transport of bulk materials, containing a loading tank communicated with the washing tank, a water separator and a lifting device connected to the transport pipeline through the pump with a loading tank, so that to ensure reliable operation of the installation batch mode, it is equipped with an automatic valve installed on the transport pipeline and connecting the loading tank with the pump and the flushing tank, while the load receiving device GUSTs provided with a sensor associated with the automatic valve.
