Изобретение относитс к области канализации .This invention relates to the field of sewage.

Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс бункер дл обезвоживани песка, содержащий цилиндрический корпус с коническим днищем, внутри которого размещены сборный желоб и вертикальный сто к дл удалени отсто вщейс воды, а также трубопроводы дл подвода пульпы и отвода технической воды и затвор 1.The closest in technical essence and the achieved result to the invention is a sand dewatering hopper containing a cylindrical body with a conical bottom, inside of which is a collecting chute and a vertical stand to remove the settled water, as well as pipelines for the supply of slurry and removal of industrial water and shutter 1.

Недостатками известного устройства вл ютс недостаточна отмывка песка от органических загр знений (зольность песка не превышает 80-85%) и высока влажность песка (65% и более), что обусловлено сложностью удалени технической воды из бункера, уровень которой находитс ниже переливных кромок сборного желоба, и непосредственным подходом пульпы к сборному желобу.The disadvantages of the known device are insufficient washing of sand from organic pollution (the ash content of sand does not exceed 80-85%) and high humidity of sand (65% or more), due to the difficulty of removing industrial water from the bunker, the level of which is below the overflow edges of the collecting channel , and the direct approach of the pulp to the collecting chute.

Целью изобретени вл етс повышение эффективности использовани устройства за счет снижени влажности песка.The aim of the invention is to increase the efficiency of use of the device by reducing the moisture content of the sand.

Цель достигаетс тем, что устройство снабжено размещенной в верхней части корпуса и прикрепленной к стенкам сборного желоба диафрагмой с центральным отверстием, а в вертикальном сто ке выполнено в верхней его части отверстие, при этом сто к установлен с возможностью его вертикального перемещени , а трубопровод дл подачи пульпы прикреплен тангенциально к корпусу под сборным желобом .The goal is achieved by the fact that the device is equipped with a diaphragm with a central hole placed in the upper part of the body and attached to the walls of the collecting chute, and in the vertical stand the hole is made in its upper part, while the stand is installed with the possibility of its vertical movement, and the pipeline for supplying The pulp is attached tangentially to the hull under the collecting chute.

Целесообразно снабдить устройство сальником, установленным в днище корпуса под вертикальным сто ком.It is advisable to provide the device with the gland installed in the bottom of the case under the vertical stand.

На чертеже изображено предложенное устройство, вертикальный разрез.The drawing shows the proposed device, a vertical section.

Бункер дл обезвоживани песка содержит цилиндрически корпус 1 с коническим днищем 2. Внутри корпуса в верхнейThe sand dewatering bin contains a cylindrical body 1 with a conical bottom 2. Inside the body at the top

его части выполнен по всему периметру сборный желоб 3, к стенкам которого прикреплена диафрагма 4. Диафрагма расположена перпендикул рно оси корпуса и имеет центральное отверстие 5. В наклонной стенке днища 2 имеетс сальник 6, размещенный под вертикальным сто ком 7. В верхней части сто ка выполнено сквозное отверстие 8, имеющее круглую или удлиненную форму. Дл подачи пульпыits parts are made along the entire perimeter of the collecting chute 3, to the walls of which a diaphragm 4 is attached. The diaphragm is located perpendicular to the axis of the housing and has a central opening 5. In the inclined wall of the bottom 2 there is a gasket 6 located under the vertical stand 7. At the top made through hole 8, having a round or elongated shape. For pulp feeding

Claims

Pipe 9 is introduced tangentially to the body below the collecting chute. There is a pipeline 10 for discharging process water from the chute. In the lower part of the bottom, a valve 11 is installed. It is connected to the electric drive 12. The device operates as follows. Pipeline 9 sand is pulp fed to a bunker. At the same time, one hundred to seven is raised so that the opening 8 is located above the diaphragm 4 in order to avoid getting into the top of the process water. Due to the tangential arrangement of the feed pipe 9, a rotational movement of the pulp is created in the hopper. At the same time, the sand flies off to the walls of the cylindrical part of body 1 and slides along them into the conical part 2. Technical water, which is used for transporting sand, with lighter organic impurities moves from the periphery to the center. In addition to the rotational movement, this is facilitated by the central location of the opening 5 in the diaphragm 4, through which the technical water with organic impurities leaves the bunker. In order to avoid backwater, the diameter of the hole 5 should not be less than 0.15 m. The spent technical water flows through the diaphragm into the trough and is removed through the pipe 10 from the hopper. After cessation of the pulp, the sand settles for 30-40 minutes. To remove the liquid remaining in the bunker, one hundred and seven are lowered, for which purpose the electric actuator 12 is used. At the same time, the water enters the station through the opening 8 and drains into the drainage tank located under the bunker. When the hole 8 reaches the level of sediment, one hundred to raise to its original position. The dehydrated and washed sand is removed from the bunker via gate 11. The proposed bunker was tested at the aeration station of the city of Iskitim, Novosibirsk region. The operation of the known (1) and proposed (2) bunkers is characterized by the following data. Humidity Ash content of sand,% of sand,% The proposed bunker, as compared with the known one, reduces the moisture content of sand by an average of 5.54% and reduces the content of organic impurities in it by an average of 6.4%. Claim 1. Sand dewatering hopper comprising a cylindrical body with a conical bottom with a pulp supply pipe, a collecting chute with a pipe and a vertical sewer for discharging technical water and a bottom gate valve, characterized in that, in order to increase efficiency using it by reducing the moisture content of the sand, it is provided with a diaphragm with a central opening placed in the upper part of the body and attached to the walls of the collecting chute, and in the vertical stand it is made in its upper part a bore, with the stand to be installed with the possibility of its vertical movement, and the pipeline for feeding the pulp is attached tangentially to the body under the collecting chute.

2. A bunker according to claim 1, characterized in that it is provided with a bottom mounted under the vertical compaction. Sources of information taken into account in the examination 1. S. V. Yakovlev et al. Kanalizatsi, M., Stroyizdat, 1975, p. 233-234, p. 4.25.
