Description

The utility model relates to feeding or unloading devices for filters containing bulk filter material.

A device is known for hydroloading bulk filter material - sand, containing pumps supplying water under pressure, a system of distributing pipes, a portable ejector unit with rubber-fabric sleeves for connection to pressure and discharge pipes, discharge pipes for supplying a mixture of water and sand to sand washing tanks and hopper sand storage. The portable ejector unit of the device for hydroloading is made in the form of a hopper, in the bottom of which is placed a water-jet pump (ejector), which is an opposed nozzle and confuser. (the book. "Improving the quality of water" Turchinovich VT, NKTP USSR, the Main edition of construction literature, 1935, p.151-153).

The disadvantages of the device are the occurrence of reverse current and losses of overloaded material when the pumps are stopped, kinks and blockages of the hoses, as well as the inability to monitor the movement of the hydraulic mixture (pulp) in the hoses and pipelines, which eliminates process control. The disadvantages include the need for manual transfer of the ejector unit when servicing filters VPU (water treatment plant).

The closest in purpose and technical nature of the device is known for the hydroloading of filtering material, namely, for loading granular materials — anthracite, sulfonic charcoal, ion-exchange resins — into the filters and unloading from them through inlet and outlet pipes. The device includes a container for hydraulic overload of filter material with nozzles for hydraulic overload, a filter with filtering material, mobile (on wheels)

a hydraulic conveyor with a hopper and an ejector connected to a pressure pipeline, a hydraulic overload pipeline system, part of which is made in the form of a stationary rigid (metal) pipeline, and the other part is in the form of flexible rubber-fabric hoses (book "Reference book on water treatment of boiler plants" O. Lifshits ., ed. "Energy", 1976, S. 114-115).

The disadvantages of this device are the increased complexity and maintenance complexity associated with the need to completely or partially empty the filters, installation and dismantling of pipes and plugs when connecting and disconnecting the pipeline system, low operational reliability due to clogging occurring at the junction of the stationary pipeline and flexible hoses (from -for sharp, but not smooth turning sections (elbows) and due to the heterogeneity of the material of the pipeline system) and in places of kinks (deformation) sleeves (reduction of the bore due to insufficient elasticity of their walls). Clogging causes shutdown and long downtime, loss of water and overloaded filter media. Clogging prevention is difficult due to the inability to monitor the movement of the hydro-mixture (pulp) and to control the flow rate in the pipeline system. These disadvantages are especially evident when using countercurrent technology.

The technical result of the proposed utility model is to reduce the complexity and simplify maintenance, increase the operational reliability of the device for hydroloading and prevent loss of filter materials and water.

The technical result is achieved by the fact that in the device for hydro-loading of filtering materials, including a container for hydro-loading of filtering materials, a mobile hydraulic conveyor with an ejector connected to a pressure pipe, inlet and outlet pipes for hydro-loading installed in the served filter

filtering material, the piping system, the inlet and outlet pipes of the served filter and containers for hydroloading are equipped with shutoff valves, the entire piping system is made of flexible sleeves made of transparent material with the possibility of sequential jointing of flexible sleeves, the walls of flexible sleeves are reinforced with an elastic-elastic spiral, with the ends of the sleeves equipped with quick couplings.

The utility model is illustrated by schematic drawings, in which Fig. 1 shows a device for hydro-loading of filter materials during the operation of loading the filter material from the tank for hydro-loading into the filter;

figure 2, the same, when performing the operation of the initial loading in the filter;

figure 3, the same, when the filter material is overloaded from the filter into the backwash tank;

figure 4, the same, when the overload of the filter material from the filter to the filter.

The device for hydraulic overloading of filtering materials includes, connected with the pressure pipe 1, a hydraulic conveyor 2 on a wheeled drive with a hopper 3, in the bottom of which a water ejector is installed 4. The device also includes a hydraulic overload tank 5 with inlet and outlet pipes, an ion exchanger 6, with an inlet 7 and outlet 8 nozzles for hydroloading, equipped with shutoff valves - ball valves 9. The filter is also equipped with nozzles for input 10 of source water, output 11 of treated water, input 12 and output 13 of regeneration solution, input 14 and output 15 of wash water. All of these nozzles are equipped with shut-off valves. The piping system of the device, which serves for hydraulic communication of the hydraulic conveyor 2, tank 5 and filter 6 is made of sequentially jointed flexible hoses 16 of transparent synthetic material reinforced

elastic-elastic plastic spiral (not shown). The ends of the sleeves are equipped with quick-detachable fastening connections, for example, tape coupling clamps 17.

A device for hydroloading filter materials works as follows.

For the initial loading of the filter material into the filter 6 (Fig.2), the hydraulic distributor 2 with the ejector 4 is connected by flexible sleeves 16 with transparent walls to the inlet pipe 7 of the filter with a ball valve 9 and to the pressure pipe 1 of the source water with a valve. These connections are uncomplicated due to the presence of quick disconnect tape tie clamps 17. The cavity of the filter 6 is filled with some volume of water. When communicating with the pressure pipe 1, the ejector 4 of the hydraulic conveyor 2 creates a pressure in the sleeves 16, so that the bulk filter material supplied to the hopper 3 by any loading means is pumped into the filter 6 through the flexible sleeves 16 in the form of a hydraulic mixture (pulp). At the same time, preventing overflow of the loaded filter with water, the valve 9 and the valve on the pressure pipe 1 smoothly shut off. After loading the main filter material in a predetermined volume (to the required level), an inert bulk material can be loaded into the filter in the same way. Due to the elastic elasticity of the sleeves 16, additionally attached to them by a reinforcing spiral, sharp kinks of the sleeves and blockages are eliminated, and due to the transparency of the walls of the sleeves, the presence of shut-off valves and valves, the hydraulic loading process is controlled and controlled by the operator (pulp water cut).

If it is necessary to flush the filter material outside the cavity of the filter 6, this material is hydraulically loaded into a tank for hydroloading 5 (called a backwash tank) or (if there is no one) into a backup filter. For this, the flexible sleeve 16 is mounted on the outlet pipe 8 and the upper pipe of the container 5 or the backup filter 5 (Fig. 3 and Fig. 4). In this case, the cavity of the discharged filter 6 located

under some pressure, there is no need to first empty it from water: it is enough to turn off the valve 9 during the installation of the flexible hose 16. Hydraulic overloading is carried out by opening the valve of the source water supply pipe 10 on the discharge filter and opening the valve 14 from the bottom. At the end of the overload, the valves are closed and the filter material is flushed in the tank 5 or the backup filter. To transfer the washed filter material from the tank 5 (or the backup filter) to the filter 6, use a hydraulic conveyor 2 (Fig. 1 shows a variant of the overload circuit from the backwash tank). For this, the hydraulic conveyor 2 is connected with flexible sleeves 16 to the upper pipe 9 of the filter 6 and to the pressure pipe 1. The free end of the sleeve is fed to the hydraulic conveyor 3, the other end of which is connected to the outlet pipe of the backwash tank 5. The process of hydraulic overloading the filter material is carried out as well as during the initial loading of the filter (figure 2).

Using the proposed technical solution, a reduction in the complexity and simplification of the maintenance of the device, an increase in operational reliability and the prevention of losses of filtering materials and water is achieved due to the better hydromechanics and control of the mass transfer process. The proposed device for hydroloading provides the movement of filter materials of production volumes and to the required distances, so that progressive counterflow technology can be easily implemented even at large runways. In addition, the overall production culture of the water treatment site is significantly increased.
