Main purpose of the present invention provides a kind of self-powered mechanical filter tank that can overcome the above-mentioned deficiency of prior art, its control device should simple structure, dependable performance, pond reduce deeply, empty water consumption is few, and the backwash head of being convenient to realize deceleration filtering, can keep setting reliably can be saved in technological process again to overcoming movable weir plate highly existing technology head is set.

This invention is to the effect that:

(1) in the filter tank outer setting of all sealings the self-powered mechanical device.The self-powered mechanical device is by support, rotating shaft is located at the lever that can rotate around the axis on the support in vertical plane, timing tank, be located in the timing tank and link to each other with lever one end by rope, utilize the floating drum that buoyancy or gravity promote or the tractive lever rotates up and down, on lever, change by the force application location of activity change longitudinally lever center of rotation generation direction according to the lever inclination angle, the object of the rotating torque that varies in size (abbreviation movable body), the lever center position is utilized lever to rotate to lift or payout control lifts the ropewinder that valve opens and closes thereby be fixed on, the end, be higher than final water level in the upper curved section top, last bend pipe mouth be located at when recoil stops in the timing tank can air inlet the position, lower nozzle leads to push up in the pressure-bearing top board of filter tank has recoil end time-delay water inlet, there is the siphon destructing tube of scavenging action (if when clear water water in a canal position is less than or equal on the top in the pressure-bearing top board of arranging when moving continuously inside, filter tank then can air inlet) at the water inlet initial stage, be positioned at the valve (be called for short shakedown valve) of the shakedown vacuum at siphon destructing tube top, thereby the timing valve of the pipe flow speed adjustment recoil time length that communicates with the filter tank by the control timing tank constitutes;

(2) at filter tank drainpipe outlet place, setting reduces the recoil flow plug of choked flow effect with the prolongation of recoil time, by lever, be fixed on its top of lever one end and have inlet opening, bottom and hinder the container (be called for short choked flow head) of part current by the water outlet section that reduces drainpipe outlet when being provided with leaking hole, recoil beginning by, recoil beginning back no longer choked flow because inner inlet avales, be fixed in the lever other end, when the inner water yield of choked flow head is leaked the counterweight that the choked flow head is resetted, the rotating shaft that is positioned at lever center of rotation place constitutes;

(3) the automatic adjusting activity weir plate that is provided with on the drainpipe underwater of filter tank by movable weir plate, be fixed on weir plate center of rotation place rotating shaft, be arranged in the clear water canal and link to each other with movable weir plate lower inside when clear water channel water position descends by rope and reduce pool level to keep the floating drum of setting the backwash head, to be positioned at movable weir plate bottom the automatically reset counterweight of weir plate is constituted by the movable weir plate of tractive;

What (4) be arranged on the drainpipe of filter tank control filter tank drainpipe current lifts valve by valve body, be fixed on the valve seat at the end in the valve body, be pressed on valve seat work when closing and go up the closure member that stops current to pass through, one end and closure member link to each other the other end with lift the force transmission element that apparatus is connected, adopt waterproof, high resilience, the reliable flexible material of intensity is made, stop current to leak at dip direction, be positioned at valve inner, the closure member top, the centre is installed with the resistance missing part that force transmission element top is sandwiched between maintenance flange plate (when adopting gland, the resistance missing part is located between valve body top and the gland) and the valve body and constitutes.

The design of lever is relevant with movable body.When movable body is the durable object that can roll or slide, spring is set or rubber bodies is come buffering percussive force at the final position of movable body.The motion critical condition of movable body, its numerical value are decided by the material and the surface condition of shape, movable body and the lever of movable body.When movable body adopts nontoxic when being convenient to flowing liquid, for avoiding evaporating, the lever of liquid motor segment must be the pipeline of one section liquid closed at both ends that can flow, and be provided with can and the valve of discharge liquid, and flowing of liquid is relevant with flox condition.

The self-powered mechanical device drives a device at least by tractive or shake-up, finishes control task.

The adjusting of choked flow time mainly is to realize the time of rotating shaft both sides moment contrast when changing work, way has two kinds easily: be provided with one in the counterweight side can be along lever slippage, fixing to the fine setting counterweight that plays regulating action, or the valve that adjustable orifice hole size is set on container inlet opening or leaking hole is realized.

If, in the above-mentioned flow plug of mentioning, realize by the spring that is provided with near the lever of head suspension other end on the drainpipe is fixed on the choked flow head for the choked flow effect that the makes flow plug variation with the recoil time reduces gradually.

The flow plug of another kind of pattern be by an end evenly be fixed on around the drainpipe, the other end hangs spring and the choked flow head that choked flow head quantity is no less than two and constituted, choked flow head top has the bottom, inlet opening and has leaking hole.This design can be avaled the choked flow head gradually and be reduced the choked flow effect gradually when recoil, when recoil finished, the water in the container continuously outflowed, and flow plug rises gradually and resets at last.

The adjusting of choked flow time can by increase, subtract spring or fastening compression, pull-off spring is realized.

The automatic adjusting activity weir plate of another kind of pattern mainly is made of movable weir plate, the container that is fixed on movable weir plate upper outside, the counterweight that is fixed on movable weir plate bottom, is installed on the flowing flux by the rotating shaft that is fixed on movable weir plate center of rotation.The characteristics of the weir plate of this pattern are that unlatching is relevant with the overflow time, when the filter tank total number of divisions more after a little while, can consider this pattern, the upper and lower of container has inlet opening and leaking hole, during the recoil beginning, backwashing water is when overflow is fallen from weir crest, part water enters in the container by the inlet opening, when moment that the overturn moment of container one end produces greater than counterweight, movable weir plate action, weir head reduces, recoil finishes, water in the container is spilt by leaking hole, and when reseting torque that the overturn moment of container one end produces less than counterweight, weir plate resets.

For preventing that weir plate when work from rotating excessively, above-mentioned movable weir plate is supported on the gag lever post on the water channel base plate when on the water channel sidewall of the movable weir plate outside at rotation direction design maximum opening place side spacer pin being set or being arranged on action in the container bottom.

During the occasion of when automatic adjusting activity weir plate is used to be failure to actuate, not leaking, can on the working face of closing between movable weir plate and the water channel, use elastic sealing element.

The closure member that lifts valve is combined by elaxtic seal and on-deformable rigid body spare.Sealing force is mainly leaned on liquid medium static pressure and closure member to conduct oneself with dignity and is provided, and when seal pressure is not enough, can meet design requirement by spring, improvement sealed surface texture and encapsulant are set.Lift valve and have following characteristics:

One, the keying of valve relies on and to lift rope or payout moves, and opens and closes fast, is convenient to the automatic control of self-powered mechanical device.Two, simple in structure, its intake tunnel can arrange that needs decide according to draining, both can cast, also can weld assembly unit processes, easy-to-mount structural shape is adopted in the connection that lifts part and closure member, comprising will lift part, closure member, the resistance missing part uses as a whole or change, and therefore processes repair, dismounting all is easy to.Three, be convenient to repacking, opening force can be provided by electric device (electromagnet).

The present invention compared with prior art has following advantage:

One, utilize the water level feature to move fully to realize main program automatically the self-powered mechanical device of control compare as the automatic control technology of technological core with computer, do not need the high-tech equipment, flushing devices such as water pump, air blast need be set, electronic or operated pneumatic valve need be set, therefore, equipment is simple, reliability is high, reduced investment, maintenance engineering amount are little, do not need the external world provide the energy, be that the automatic control technology that cost forms siphon is compared with the loss water yield, action is fast, technology is reliable, save the water yield, increased greater functionality.

Two, adopt the Chi Tiyu of complete closed that the drainpipe combination that lifts valve gear is installed, in fact one section of centre body inside, pond can being regarded as siphon piping in the backwash stage, the recoil head that is provided is poor (or the water surface is poor) of clear water water in a canal position and automatic adjusting activity weir plate place pool level, can keep the backwash head of setting, give resistance system in the employing, use the clear water reserviors water yield condition is provided, and needn't consider that part of pond of filtering cloth head height is (when pushing up in clear water water in a canal position is equal to or higher than filter tank pressure-bearing top board, this part is born by pressure-bearing top board and filter tank water inlet pipe), it is dark with this part pond that this layout is saved empty water consumption, thereby saved and got rid of the needed recoil time of this part empty water consumption, and can reduce the filter tank lattice, also can adopt two covers or overlap shared floating drum of self-powered mechanical device and timing tank synchronization action more, therefore all can use in large, medium and small water factory.

Three, do not regulate in the clear water canal at backwash head on the technology arrangement, available water head is few, and import and export can not make to fall layout, water inlet pipe further reduces with the valve control loss of flood peak, are convenient to adopt the deceleration filtering mode.

Four, be convenient to regulate.Timing in the self-powered mechanical device partly is located at the outside, filter tank, is very easily to the filter tank management.Can regulate expansion rate by the aperture that adjusting lifts between valve opening or the recoil flow plug and the draining mouth of pipe, by adding on the floating drum in timing tank that counterweight prolongs the work period, shorten its work period by the light matter body (as wood) of setting up certain altitude between lever and floating drum, the adjustment of work period can also realize by changing movable body motion critical value.

The setting of five, time-delay water inlet, pressure-bearing top board, water inlet after the recoil is flowed to be eliminated substantially to the impact that is adsorbed on the suspension on the filtering material particle, the effluent quality that filters after beginning is improved, owing to be provided with the recoil flow plug, when beginning, backwash slowly starts, avoid supporting layer to be got excited and guarantee that to prolonging the filter bed life-span filtering water is favourable, by the backwash head that automatic adjusting activity weir plate can stable maintenance be set is set; To guaranteeing the backwash quality, guarantee that filter quality is helpful, owing to be convenient to adopt the deceleration filtering method, after adopting the deceleration filtering mode, the filter tank effluent characteristics will be better than constant speed filter water quality.

Six, compare with valveless filtering pool, because inspection manhole is located at the timing tank bottom, inspection manhole can design greatlyyer, convenient construction and maintenance, and timing tank is located at the outside and communicates with the filter tank by pipeline, is convenient to air intake-exhaust and observes loss of flood peak growth pattern.

Seven, control automatically owing to adopting the self-powered mechanical device to carry out main program, needn't use and manually carry out regular job, less demanding to operator quality, adjust easily, on the self-powered mechanical device, set up parts and can increase additional function, the contact that can touch the relay button for example is installed on lever, and the operator on duty knows promptly in night shift room when which filter tank begins recoil, when recoils and finishes promoting that water plant automation and scientific management are helpful.

The present invention is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a self-powered mechanical filter tank operation principle schematic diagram.

Fig. 2～Fig. 8 is automatic adjusting activity weir plate.

Fig. 9～Figure 16 is for lifting valve.

Figure 17, Figure 18 are flow plug.

Example 1: Figure 1 shows that the situation the when filter tank begins to filter.The self-powered mechanical device is located at the outside, filter tank of whole sealings, timing tank 2 communicates with the filter tank by pipeline and the timing valve 9 that is located at timing tank 2 bottoms, there is a floating drum 3 to be located at can link to each other on the support 11 in the timing tank 2 at an end of the lever 7 of vertical rotation by rope 6 and rotating shaft, object (abbreviation movable body) 8 along lever 7 longitudinally-movings is arranged, in the lever center of rotation one ropewinder 10 is arranged, have in the end of lever 7 water inlet pipes one side and to touch foot (can be designed to have after stressed the device of certain stroke) 14 and broken away from and the contacting of normal opening apparatus 15, water inlet valve 16 has been opened, precipitation water enters filter through water inlet pipe, the air of filter tank accumulated inside is discharged by the upper orifice of the siphon destructing tube 4 that lower nozzle communicates with the filter tank, prolongation along with filtration time, the loss of flood peak continues to increase, the water level of timing tank 2 constantly rises, floating drum 3 promotes to rest top lever 7 thereupon and clockwise rotates, when timing tank 2 water levels arrive final water level, movable body 8 on the lever 7 is because lever 7 inclination angles surpass angle of repose, and move to right-hand member, the normal opening apparatus 15 water inlet valve 16 of foot 14 shake-up that touch on the lever 7 are closed, ropewinder 10 rotates to lift in company with lever 7 and lifts valve 19 on the drainpipe of filter tank, backwashing water carries out backwash by clear water canal 18 through water distribution system 23, flushing waste water is through rhone, when lifting valve 19 from drainpipe 20 terminal discharges, a water enters top and is provided with inlet opening 21-1-1, the bottom is provided with in the container 21-1 (being called for short the choked flow head) of leaking hole 21-1-2, when the water yield reaches certain value, container dead weight, when water heavily reaches the moment that moment that the water impact active force produces by lever 21-5 countershaft 21-2 produces greater than other end counterweight 21-3 countershaft 21-2, choked flow head 21-1 avales (when the flow plug employing evenly is fixed on drainpipe by at least two one ends around, spring 21-4 and top that one end evenly hangs choked flow head 21-1 are provided with inlet opening 21-1-1, when the bottom is provided with the flow plug 21 that the container 21-1 of leaking hole 21-1-2 constitutes, choked flow head 21-1 sinks gradually), recoil water changes from small to big and reach required value most.In the recoil process, if water level descends in the clear water canal 18, for keeping the backwash head of setting, the floating drum 22-8 that is located in the clear water canal 18 affects movable weir plate 22-1 22-3 rotation around the shaft by fixed pulley assembly 17, make the water level at drainpipe 20 mouth of pipe places fall value and can compensate clear water channel water position drop-out value (rotate excessively for preventing weir plate, can in the clear water canal, establish shelves and prevent the floating drum excessive descent or establish stop bits 22-4 or gag lever post 22-6).Continuation along with the recoil time, water level in the timing tank 2 continues to descend, floating drum 3 affects lever 7 counterclockwise to rotate by rope 6, the recoil time is (time length is by the aperture decision of the timing valve 9 of control timing tank water level decrease speed) when using up, because damage of water block siphon destructing tube 4 upper orifice air inlets, filter tank recoil siphon is destroyed, and backwash is finished in the filter tank.When lever 7 rotates inclination angles when surpassing the angle of repose of movable body 8, movable body 8 end motion left lifts valve 19 and resets down and close in deadweight (or be added with spring reset force is provided) effect, and water inlet valve 16 is opened, and filtration is recovered in the filter tank.Water in flow plug 21 heads spills when a certain amount of, and flow plug 21 resets.Clear water canal 18 water levels are replied just often, and floating drum 22-8 resets and stopped tractive to movable weir plate 22-1, draws together weir plate 22-1 and resets under the effect of counterweight 22-2.

When backwash need be forced in the filter tank, whether the water level decision of looking timing tank 2 needed to close or valve 9 during accommodometer.Tearing rope 13 then makes lever 7 turn to the backwash position to get final product.

When needs maintenance lifts valve 19, open shakedown valve 5, rotating lever 7 or control normal opening apparatus 15 water valve 16 is closed overhauls then.

The water of whether taking clear water reserviors carries out backwash and should be determined by design arrangement.

The adjusting of expansion rate is to realize by the aperture that adjusting lifts valve 19.

When needs maintenance filter tank is inner, can utilize lever 7 floating drum of slinging, lateral rotation lever 7 (support 11 can be installed turning cylinder, bearing, make lever energy lateral rotation) puts down floating drum then, the vexed plate 1 of the hand-hole of slinging again, dismounting for the ease of the vexed plate 1 of hand-hole, the vexed plate 1 of hand-hole needn't seal with securing member, utilizes the deadweight of the vexed plate 1 of hand-hole as sealing force sealing ring to be out of shape and reaches.

The water inlet valve can adopt normal closing apparatus, also can or touch and control by movable body 8 tractives.The filter tank water inlet also can be adopted other modes.

Fixed pulley assembly 17 is made up of fixed pulley, lever, bearing part, turning cylinder.Fixed pulley cooperates with rope.Securing to buoy 22-8 of lever, one is movable weir plate 22-1, whether lever needs to be provided with the position decision by floating drum 22-8, from weir plate more fully by rope drive.

When needs are adjusted the work period, can prolong the work period by on floating drum 3, adding counterweight, shorten the adjustment of its work period, work period by the light matter body (for example wooden) of between lever 7 and floating drum 3, setting up certain altitude and can also realize by the angle of repose that changes movable body 8.

Example 2: in shape filter tank, large-scale garden, use the self-powered mechanical device.

Lift valve 19 by valve body 19-3, be fixed on the valve seat 19-1 at the end in the valve body 19-3, be pressed on when closing on the valve seat 19-1 working face close 19-2, one end and closure member 19-2 link to each other the other end with lift the force transmission element 19-4 that apparatus is connected, be positioned at valve body 19-3 inside, closure member 19-2 top, the centre is installed with force transmission element 19-4, the resistance missing part 19-6 that top is clipped between maintenance flange plate 19-5 and the valve body 19-3 constitutes, rely on the sealing of gravity or elastic force, dependence lifts or the mode loosened is controlled the logical of current and closed, lift valve if only use one in the large-scale filter tank, valve seat, the size of closure member etc. will be done very greatly, to make the sealed precision that lifts valve require to improve a lot, it is very heavy that the self-powered mechanical device will become, draining is arranged and is also become unfavorable, if use a plurality of self-powered mechanicals and lift valve, start synchronously, the problems referred to above have just solved.For example a timing tank 2 and floating drum 3 are set at top, shape filter tank, garden, lever 7 one ends of many group self-powered mechanical devices arrange that evenly (favourable to synchronization action like this) is on floating drum 3, when floating drum 3 actions, it is convenient equally that self-powered mechanical device synchronization action, large-scale filter tank are used the self-powered mechanical device.

The present invention enlarges the example of range of application:

Example 1: in self-powered mechanical filter tank, the self-powered mechanical device is actually a machine that utilizes water potential that power is provided.For some mountain areas, if flowing water is continuous, the self-powered mechanical device can be used as drive mechanism, water feed apparatus can be made up of Xiao Chi and valve, and jettison gear adopts the bell-jar siphon drainage pipe.When water level rose to certain position, water was just released rapidly, sluiced by water inlet, and floating drum is activation lever work repeatedly up and down.This design is very simple, and management is made and all is easy to.

Example 2: with automatic adjusting activity weir plate flood control

Because of rise the suddenly thing that storehouse dike, the shoal of fish escape of destroying by rush of water of heavy rain reservoir, fish pond water level happens occasionally, will avoid these losses if after the weir crest overflow is set on the wasteway, prolong the automatic adjusting activity weir plate (seeing Fig. 6, Fig. 7, Fig. 8) that reduces pool level automatically in time.For fish pond that does not often discharge water or reservoir, automatically adjusting activity weir plate is established sealing ring 22-7 or the wasteway floor elevation is arranged in more than the ordinary water level in closed location.When the water yield is little, water pushes up from automatic adjusting activity weir plate and overflows, and when the water yield was big, current overflowed distance and far fall into intake chamber 22-5-2, when water inlet in the container 22-5 reaches a certain amount of, movable weir plate 22-1 22-3 around the shaft rotates, and begins to sluice, and sequence number 22-6 is a gag lever post, when container 22-5 water is extremely a certain amount of from leaking hole 22-5-1 leakage, movable weir plate 22-1 resets under the effect of counterweight 22-2, and movable weir plate 22-1 will operate repeatedly when longer the mountain torrents duration.(sequence number 24 is the grid that block of anti-fish escape among Fig. 8)
