Изобретение относится к сельскохозяйственному машинострое- нию, в частности к способам и устройствам для приготовления жид- ких удобрений путем смешивания с водой карбамида, аммиачной се- литры, дефекатов, фосфорных, калийных, сульфатных и иных мине- ральных, органоминеральных и органических удобрений и получения концентрированных или рабочих растворов и суспензий, готовых для дальнейшей транспортировки и применения. The invention relates to agricultural machinery, in particular to methods and devices for the preparation of liquid fertilizers by mixing with water urea, ammonium nitrate, defecates, phosphorus, potassium, sulfate and other mineral, organomineral and organic fertilizers and obtaining concentrated or working solutions and suspensions, ready for further transportation and use.
Предшествующий уровень техники. Prior art.
Из уровня техники известна установка для приготовления жид- ких удобрений, которая содержит весовое устройство, насос с трубо- проводами, мельницу мокрого помола и смесительный бак с мешал- кой и устройством отвода осадка, выполненным в виде нескольких пристеночных трубопроводов с накопителями, конусообразным сет- чатым фильтром, и установленным над ним направляющим элемен- том в виде обратного усеченного конуса. Установка снабжена распре- делителем для реверсирования потоков жидкости и центробежным разделителем, установленным соответственно на всасывающем и
нагнетательном трубопроводах насоса (RU 2034637, 10.05.1995). From the prior art, an installation for the preparation of liquid fertilizers is known, which contains a weighing device, a pump with pipelines, a wet grinding mill and a mixing tank with a stirrer and a sludge removal device made in the form of several wall pipelines with accumulators, a conical mesh filter, and a guiding element in the form of an inverse truncated cone installed above it. The unit is equipped with a distributor for reversing liquid flows and a centrifugal separator installed respectively on the suction and discharge pipelines of the pump (RU 2034637, 10.05.1995).
Недостатками данной установки является низкая концентрация действующего вещества в растворах удобрений, низкое качество удобрений и низкая эффективность работы, не возможность получе- ния высококонцентрированных растворов азотных удобрений и от- сутствие возможности растворения сложных минеральных удобрений. The disadvantages of this unit are the low concentration of the active substance in the fertilizer solutions, the low quality of fertilizers and low work efficiency, the inability to obtain highly concentrated solutions of nitrogen fertilizers and the lack of the possibility of dissolving complex mineral fertilizers.
Наиболее близкой к заявляемому изобретению является уста- новка для приготовления жидких комплексных удобрений, содержа- щая смесительный бак с коническим днищем, выходное отверстие ко- торого через насос с роторно-пульсационным аппаратом (РПА) со- единено с входом в проточный нагреватель, выход которого соединен с гидромешалкой, расположенной в смесительном баке. Установка имеет устройство верхнего налива смесительного бака и загрузочный бункер, который соединен со смесительным баком шнеком подачи су- хих компонентов. (RU 2686149, 24.04.2019). Способ получения жид- ких удобрений, реализуемый при работе данной установки, заключа- ется в смешивании сухих компонентов с водой в смесительном баке с коническим днищем, и последующей циркуляции получаемого рас- твора или суспензии, до полной готовности, через теплообменник по- средством насоса с роторно-пульсационным аппаратом и перемеши- вания в смесительном баке, посредством гидромешалки.
Недостатками данной установки является сложность конструк- ции, обусловленная в частности наличием загрузочного бункера, со шнеком подачи сухих компонентов и повышенные энергозатраты, связанные как с необходимостью привода шнека подачи сухих ком- понентов, так и с необходимостью постоянного нагрева большого объема воды в процессе работы установки. Это связано с тем, что с начала смесительный бак заполняется водой, затем включается насос с роторно-пульсационным аппаратом и проточный нагреватель и лишь, потом, через одну минуту, включается шнек для подачи сухих компонентов. Closest to the claimed invention is an installation for the preparation of liquid complex fertilizers, containing a mixing tank with a conical bottom, the outlet of which is connected through a pump with a rotary-pulsating apparatus (RPA) to the inlet to the flow-through heater, the outlet of which connected to a hydro-mixer located in the mixing tank. The installation has a top loading device for the mixing tank and a loading hopper, which is connected to the mixing tank by a screw for feeding dry components. (RU 2686149, 24.04.2019). The method of obtaining liquid fertilizers, which is implemented during the operation of this unit, consists in mixing dry components with water in a mixing tank with a conical bottom, and then circulating the resulting solution or suspension, until complete readiness, through a heat exchanger using a pump with rotary-pulsation apparatus and mixing in a mixing tank by means of a hydro-mixer. The disadvantages of this installation are the complexity of the design, due, in particular, to the presence of a loading hopper with a screw for feeding dry components and increased energy consumption associated both with the need to drive the screw for feeding dry components, and with the need for constant heating of a large volume of water during the operation of the installation. ... This is due to the fact that from the beginning the mixing tank is filled with water, then the pump with a rotary-pulsating device and the flow heater are turned on, and only, then, after one minute, the auger is turned on for supplying dry components.

The technical result to achieve which the present invention is directed, in part of the method, consists in reducing energy consumption during its implementation, and in the part of the device, in simplifying the design of the installation performing the method.
Указанный технический результат, в части способа, достигается тем, что при приготовлении жидких удобрений, путем смешивания сухих компонентов с водой в смесительном баке с коническим днищем, и последующей циркуляции получаемого раствора или суспензии через теплообменник, посредством насоса с роторно-пульсационным аппа-
ратом, и перемешивания в смесительном баке, посредством гидроме- шалки, до полной готовности раствора или суспензии, с начала в сме- сительный бак загружаются сухие компоненты, а затем в него, в район конического днища, подается вода под давлением, обеспечивая гидро- смыв полученной смеси на вход насоса с роторно-пульсационным ап- паратом. The specified technical result, in terms of the method, is achieved by the fact that when preparing liquid fertilizers, by mixing dry components with water in a mixing tank with a conical bottom, and then circulating the resulting solution or suspension through a heat exchanger, by means of a pump with a rotary-pulsating apparatus, rat, and mixing in the mixing tank, by means of a hydraulic mixer, until the solution or suspension is completely ready, from the beginning dry components are loaded into the mixing tank, and then water under pressure is fed into it, in the area of the conical bottom, providing hydro flushing the resulting mixture to the pump inlet with a rotary-pulsating device.
Технический результат в части упрощении конструкции уста- новки достигается тем, что установка, содержащая смесительный бак с коническим днищем, выходное отверстие которого через насос с РПА соединено с входом в проточный нагреватель, выход которого соединен с гидромешалкой, расположенной в смесительном баке, снабжена водоподводящим патрубком, размещенным в коническом днище смесительного бака выше выходного отверстия и соединенным с источником воды под давлением. Гидромешалка состоит, по мень- шей мере, из трех форсунок, при этом центральная форсунка направ- лена в центр смесительного бака, в сторону выходного отверстия, а остальные направлены по касательной к боковой поверхности смеси- тельного бака. В качестве источника воды под давлением может ис- пользоваться емкость с водой, с которой водоподводящий патрубок соединен через водяной насос или магистральный водопровод, с кото- рым водоподводящий патрубок соединен через запорный кран и счет-
чик воды. В качестве емкость с водой может использоваться бак, ав- томобильная или железнодорожная цистерна.

A tank, car or railroad tank can be used as a container with water.

Изобретение поясняется следующими графическими материалами: Фиг. 1 - принципиальная схема установки с водоснабжением из емко- сти с водой посредством насоса. The invention is illustrated by the following graphical materials: FIG. 1 is a schematic diagram of an installation with water supply from a tank with water by means of a pump.
Фиг. 2 - принципиальная схема установки с водоснабжением из маги- стрального водопровода. FIG. 2 is a schematic diagram of an installation with water supply from the main water pipeline.
Установка с водоснабжением из емкости с водой (Фиг. 1) состоит из смесительного бака 1 с коническим днищем 2 и выходным отверстием 3. В коническом днище 2, выше выходного отверстия 3, размещен во- доподводящий патрубок 4, соединенный с емкостью с водой 5 через насос 6. Выходное отверстие 3 смесительного бака 1, через насос с РПА 7, соединено с входом в проточный нагреватель 8. В качестве проточного нагревателя используется дизельный теплообменник. Вы- ход проточного нагревателя 8, через трехходовой кран 9, соединен с гидромешалкой 10, расположенной в смесительном баке 1. Гидроме- шалка 10 состоит из трех форсунок, при этом центральная форсунка направлена в центр смесительного бака 1, в сторону выходного отвер- стия 3, а две другие направлены по касательной к боковой поверхно-
сти смесительного бака 1. Установка с водоснабжением из маги- стрального водопровода (Фиг. 2) имеет такую же конструкцию, как и установка с водоснабжением из емкости с водой и отличается тем, что водоподводящий патрубок 4, соединен с магистральным водопрово- дом 11 через кран 12 и снабжен счетчиком воды 13. The installation with water supply from a container with water (Fig. 1) consists of a mixing tank 1 with a conical bottom 2 and an outlet 3. In the conical bottom 2, above the outlet 3, there is a water supply pipe 4 connected to a container with water 5 through pump 6. The outlet 3 of the mixing tank 1, through the pump with RPA 7, is connected to the inlet to the flow heater 8. A diesel heat exchanger is used as the flow heater. The outlet of the flow heater 8, through a three-way valve 9, is connected to a hydro-mixer 10 located in the mixing tank 1. The hydro-mixer 10 consists of three nozzles, while the central nozzle is directed to the center of the mixing tank 1, towards the outlet 3 , and the other two are directed tangentially to the lateral surface mixing tank 1. Installation with water supply from the main water supply (Fig. 2) has the same design as the installation with water supply from a container with water and differs in that the water supply pipe 4 is connected to the main water supply 11 through a tap 12 and is equipped with a water meter 13.
Заявленный способ для приготовления жидких удобрений осуществ- ляется заявленной установкой, которая работает следующим образом. The claimed method for the preparation of liquid fertilizers is carried out by the claimed installation, which operates as follows.
Непосредственно в смесительный бак 1 загружается определенный (расчетный) объем сухих компонентов, необходимых для получения жидкого комплексного удобрения определенного состава и концен- трации. Затем включается подача воды под давлением через водопод- водящий патрубок 4. Вода смешивается с сухими компонентами, вступая с ними в реакцию, а полученная смесь накапливается в ниж- ней части смесительного бака 1. После подачи определенного объема воды, который контролируется или по времени включения насоса 6, при подаче воды из емкости 5, или с помощью счетчиком воды 13, при подаче воды из магистрального водопровода 11, включается насос с РПА 7. Насос с РПА 7, сочетают в себе принципы работы, как пере- качивающего устройства, так и универсального высокоэффективного смесителя, активатора, диспергатора, дисмембратора и гомогенизато- ра. Насос с РПА 7, через выходное отверстие 3 засасывает смесь, об-
разовавшуюся в нижней части смесительного бака 1, и путем пульса- ционного, ударного, гидродинамического, кавитационного и ультра- звукового воздействия на нее, производит ее дальнейшее перемеши- вание и измельчение сухих компонентов, обеспечивая облегченное растворение их в воде. При растворении сухих элементов в воде про- исходит эндотермическая реакция, в результате которой температура смеси опускается, поэтому смесь прокачивается насосом с РПА 7 че- рез проточный нагреватель 8, который повышает температуру смеси до заданного значения. Из проточного нагревателя 8 смесь через трех- ходовой кран 9, поступает в гидромешалку 10. Форсунки гидроме- шалки 10 расположены таким образом, что боковые форсунки закру- чивают поток против или по часовой стрелке, а центральная форсунка направляет поток к выходному отверстию 3. После того как в уста- новку поступит заданный объем воды (необходимый объем воды рас- считывается исходя из объема получаемого жидкого удобрения и его концентрации) подача воды прекращается. Установка продолжает ра- боту, перекачивая смесь по замкнутому контуру (смесительный бак 1 - насос с РПА 7 - проточный нагреватель 8 - гидромешалка 10 - смеси- тельный бак 1). После того как все сухие элементы полностью раство- рятся в воде, или будет получена однородная суспензия, трехходовой кран 9 переводит поток в направление патрубка 14 для выдачи готово- го раствора или суспензии.
Заявленный технический результат в части сокращение энергозатрат при осуществлении способа достигается за счет сокращения числа по- требителей энергии и энергозатрат на нагрев, приготовляемого рас- твора или суспензии, а в части упрощении конструкции установки, достигается за счет исключения ряда узлов и агрегатов при сохране- нии ее функциональных возможностей.
A certain (calculated) volume of dry components required to obtain a liquid complex fertilizer of a certain composition and concentration is loaded directly into the mixing tank 1. Then the supply of water under pressure is switched on through the water supply pipe 4. The water is mixed with dry components, reacting with them, and the resulting mixture is accumulated in the lower part of the mixing tank 1. After supplying a certain volume of water, which is controlled or by switching time pump 6, when water is supplied from tank 5, or using a water meter 13, when water is supplied from the main water pipeline 11, the pump with RPA 7 is switched on. The pump with RPA 7 combines the principles of operation of both a pumping device and universal high-performance mixer, activator, dispersant, dismembrator and homogenizer. The pump with RPA 7, through the outlet 3, sucks in the mixture, developed in the lower part of the mixing tank 1, and by pulsating, shock, hydrodynamic, cavitation and ultrasonic action on it, produces its further mixing and grinding of dry components, ensuring their facilitated dissolution in water. When dry elements are dissolved in water, an endothermic reaction occurs, as a result of which the temperature of the mixture drops, therefore, the mixture is pumped by a pump with RPA 7 through a flow heater 8, which raises the temperature of the mixture to a given value. From the flow heater 8, the mixture, through a three-way valve 9, enters the hydro mixer 10. The nozzles of the hydro mixer 10 are arranged in such a way that the side nozzles twist the flow counterclockwise or clockwise, and the central nozzle directs the flow to the outlet 3. After as soon as a given volume of water enters the installation (the required volume of water is calculated based on the volume of the obtained liquid fertilizer and its concentration), the water supply is stopped. The unit continues to work, pumping the mixture in a closed loop (mixing tank 1 - pump with RPA 7 - flow heater 8 - hydro mixer 10 - mixing tank 1). After all dry elements are completely dissolved in water, or a homogeneous suspension is obtained, the three-way valve 9 transfers the flow towards the branch pipe 14 for dispensing the finished solution or suspension. The claimed technical result in terms of reducing energy consumption during the implementation of the method is achieved by reducing the number of energy consumers and energy consumption for heating the prepared solution or suspension, and in terms of simplifying the design of the installation, is achieved by eliminating a number of units and assemblies while maintaining its functionality.
