6. Sūknis 4 ir novietots papildu kamerā 8, bet nogulu ņemšanas elements 2 ir novietots pamatkamera6. The pump 4 is located in the auxiliary chamber 8 and the sedimentation element 2 is located in the main chamber

1. Pie tam gan pirmajā, gan otrajā variantā izveidotajai kamerai 1 nogulu ņemšanas elements 2 ir aprīkots ar izplūdes vārstu 9 un tas ir izveidots kā īscaurulē, kuras viena daļa ir novietota ārpus kameras (Fig.lb). Aizvadītājelements 3 ir izveidots ar sūkni 4 savienotas spiediencaurules formā, kurai ir atplūdes vārsts 10. Izkraušanas īscaurulē 7 ir aprīkota ar sietveida filtru 11, lai pasargātu sūkni 4 no dažādu sīku priekšmetu iekļūšanas tajā, kas novērš tā bojāšanos un rezultātā paaugstina ierīces darba drošumu. Bez tam aizvadītājelementā 3 ievadāmais produkts nav turpmāk jāattīra, t.i., samazinās darbietilpība un paaugstinās iegūstamā produkta kvalitāte. Nogulu ņemšanas elements 2 var tikt aprīkots arī ar kausu 12, kas novietots, skatoties ierīces kustības virzienā, nogulu ņemšanas elementa 2 priekšējā daļā, kura atrodas ārpus kameras. Kameras 3 dibens 6 un sieniņas ar starpsienu (gan pamatkameras l, gan papildu kameras 8) ir aprīkotas ar kontroles lodziņiem. Veidojot iegremdējama tipa kameru, kameras l katra daļa ar cauruli 13 ir savienota ar atmosfēru. Veidojot daļēji iegremdējama tipa kameru, kameras 1 daļa ar tajā ievietotu sūkni 4 (Fig.2) un cauruli 13 ir savienota ar atmosfēru. Gan pamatkameras 1, gan papildu kameras 8 daļas ir izveidotas daļēji iegremdējamas caurules veidā, kurai ir apaļš vai kvadrātveida šķērsgriezums, un augšējais atvērums 14 ir novietots virs ūdens līmeņa. Kameras daļas ar nogulu ņemšanas elementu 2 vai pamatkameras 1 dibens 6 ir izveidots hermētiska vāka formā. Tā kā izkraušanas īscaurule 7 ir novietota augstāk par dibenu 6, kamerā izveidojas nostādinātājs 16, kurā nosēžas lielākie ieslēgumi, kuri atrodas izstrādājamās dūņās (akmeņi, pikuči, oļi, grants u.c.).1. In addition, for both the first and second embodiments, the chamber 1 is provided with a sedimentation element 2 provided with an outlet valve 9 and is formed as a conduit, one part of which is located outside the chamber (Fig. 1b). The discharge element 3 is formed in the form of a pressure pipe connected to a pump 4 and having a non-return valve 10. The discharge pipe 7 is equipped with a sieve filter 11 to prevent the pump 4 from entering small objects, which prevents its deterioration and consequently increases the operational safety of the device. In addition, the product to be introduced into the lead-off element 3 does not have to be further purified, i.e., it reduces labor intensity and improves the quality of the product obtained. The sedimentation element 2 may also be provided with a bucket 12 located in the forward direction of the device in the direction of movement of the device, which is located outside the chamber. The bottom 6 of the chamber 3 and the partition walls (both main chamber l and auxiliary chambers 8) are provided with control windows. Each part of the chamber l is connected to the atmosphere by a tube 13 to form an immersion type camera. By forming a semi-submersible chamber, the chamber 1 is connected to the atmosphere by a pump 4 (Fig.2) and a tube 13 inserted therein. Both parts of the main chamber 1 and the auxiliary chamber 8 are formed in the form of a semi-submersible tube having a circular or square cross-section, the upper opening 14 being placed above the water level. The parts of the chamber with the sedimentation element 2 or the bottom 6 of the main chamber 1 are formed in the form of an airtight lid. As the unloading conduit 7 is positioned above the bottom 6, a settler 16 is formed in the chamber, which settles the major inclusions contained in the sludge to be developed (rocks, pitches, pebbles, gravel, etc.).

Ieža ņemšanas elements 2 var būt izveidots lokans, īscaurules veidā. Sūknis 4 var būt centrbēdzes, vītņsūknis, gliemežtipa sūknis, virzuļsūknis, membrānas sūknis, peristaltiskais sūknis un var tikt piemeklēts, ņemot vērā izstrādājamo nogulu viskozitāti un blīvumu, kā arī dziļumu, kurā notiek izstrāde, spiediencauruļvada garumu un diametru, kā arī izkraušanas punkta pacēluma augstumu virs ūdens līmeņa.The rock extraction element 2 may be formed in a flexible, tubular manner. The pump 4 may be a centrifugal, threaded pump, worm pump, piston pump, diaphragm pump, peristaltic pump and may be selected based on the viscosity and density of the sediment to be developed as well as the depth of development, the length and diameter of the pressure line and discharge above water level.

Padeves sūknis 4 var būt aprīkots gan ar elektrisko, gan hidraulisko piedziņu (motoru). Sūkņa 4 darba, kā ari motora savienojuma ar sūkņa vārpstu drošības nolūkā, kā arī nolūkā novērst motoreļļas nokļūšanu ūdens tilpnē, sūkni 4 novieto kameras daļā, kas atdalīta ar šķērssienu 5, vai arī ievieto papildu kamerā 8.The feed pump 4 can be equipped with both electric and hydraulic drive (motor). For the sake of safety of the pump 4 as well as the connection of the motor to the pump shaft and to prevent the engine oil from getting into the water tank, the pump 4 is placed in the part of the chamber separated by a partition 5 or

Ieplūdes vārsts 9 var būt izvietots ārpus kameras 1 pirms ieža ņemšanas elementa 2 zemākā punkta (skat. Fig.lb un Fig.2) vai arī kameras iekšpusē (skat. Fig. la). Vārsta 9 novietojuma variants ārpus kameras 1 atvieglo tā vadības procesu, bet palielina spiediena zudumus pie ieejas. Tāds vārsta 9 novietojuma variants ir piemērots darbam lielos dziļumos, bet variants ar vārsta 9 novietojumu kameras iekšpusē ir piemērots darbam nelielos dziļumos.The inlet valve 9 may be located outside the chamber 1 before the lowest point of the rock pick-up member 2 (see Figs. 1b and 2) or inside the chamber (see Fig. La). The arrangement of the valve 9 outside the chamber 1 facilitates its control but increases the pressure loss at the inlet. This version of valve 9 is suitable for working at deep depths, while the version 9 of the valve 9 is suitable for working at shallow depths.

Ierīces darbības aprakstsDescription of device operation

Pirms iedarbināšanas vārsts 9 ir aizvērts un ierīci iegremdē izstrādājamā nogulu, piem., sapropela, masīvā vajadzīgajā izstrādes dziļumā tā, lai kausa 12 apakšējā plakne atrastos augstāk par dūņainā masīva viskozi plastiskā slāņa robežu un dūņaino nogulu slānis viskozi plastiskā stāvoklī atrastos virs kausa 12. Tā tiek nodrošināta iespēja to iesmelt kausā, izmantojot ārējo hidrostatisko spiedienu. Nogulu iesūkšana iegremdējamā vai daļēji iegremdējamā kamerā 1 caur kausu 12 un nogulu ņemšanas elementu 2 notiek ārējā hidrostatiskā spiediena iespaidā, kas rodas iegremdējot kameru 1. Sapropela iesūkšana kamerā 1 tiek nodrošināta uz spiediena starpības rēķina kameras 1 iekšpusē un ārpusē, jo spiediens kameras 1 ārpusē ir vienāds ar '“'lPrior to actuation, valve 9 is closed and the device is submerged in the required depth of formation of a sediment, e.g., sapropel, such that the bottom plane of bucket 12 is above the boundary of the muddy viscous plastic layer and the muddy sediment layer viscous to plastic it is possible to slip it into the bucket using external hydrostatic pressure. Suction of sediment into submersible or semi-submersible chamber 1 via cup 12 and sedimentation element 2 is effected by external hydrostatic pressure resulting from submerging chamber 1. Sapropel suction into chamber 1 is provided at the expense of differential pressure inside chamber 1, equals' '' l

Ρ_Η=γ1ι, kur h ir kameras 1 iegremdēšanas dziļums (nogulu ņemšanas elementa 2 augšējā punkta iegremdēšanas dziļums), bet spiediens kameras iekšpusē atbilst atmosfēras spiedienam. Jo lielāks ir h, jo lielāks ir spiediens kameras 1 ārpusē un jo lielāka ir ierīces iesūkšanas spēja. Lielos izstrādes dziļumos sapropeļa iesūkšanas ātrums kamerā 1 caur kausu 12 un ieža ņemšanas elementu 2 var regulēt, mainot vārsta 9 pretestību.Ρ _Η = γ1ι, where h is the depth of immersion of chamber 1 (the depth of immersion of the top of the sedimentation element 2) but the pressure inside the chamber corresponds to atmospheric pressure. The higher the h, the higher the pressure on the outside of the chamber 1 and the greater the suction capacity of the device. At large working depths, the suction speed of the sapropel into the chamber 1 through the bucket 12 and the rock pick-up member 2 can be controlled by varying the resistance of the valve 9.

Kad ir aizpildīta kameras daļa, kas aprīkota ar nogulu ņemšanas elementu 2, vai pamatkameras 1 daļa, tiek veikta tās iztukšošana caur izkraušanas īscauruli 7, kas ir savienota ar to kameras daļu, kurā ir novietots sūknis 4, vai ar papildu kameru 8, kas ir aprīkota ar sūkni 4. Padeves sūknis 4 veic nogulu ņemšanu (iesūkšanu) no kameras daļas ar nogulu ņemšanas elementu 2 vai no tās pamatkameras 1 ar neliela nogulu uzstādinājuma palīdzību, kas izveidojas kameras daļā ar nogulu ņemšanas elementu 2, vai no pamatkameras 1 ar retinājuma palīdzību, ko rada pats sūknis 4 pie ieejas sūknī, bet nogulu padevi aizvadītājelementā 3, kas ir izveidots spiediencauruļvada formā, veic ar spiedienu, ko rada pats sūknis 4 pie sūkņa izejas.When the chamber part equipped with the sedimentation element 2 or the part 1 of the main chamber is filled, it is emptied through a discharge conduit 7 which is connected to the part of the chamber in which the pump 4 is located or to the auxiliary chamber 8 which is equipped with pump 4. Feed pump 4 performs sedimentation (suction) from a chamber portion with a sedimentation element 2 or from its main chamber 1 via a small sedimentation arrangement formed in a chamber portion with a sedimentation element 2 or from a depression chamber 1 generated by the pump 4 itself at the inlet to the pump but the supply of sediment to the discharge member 3 formed in the form of a pressure pipeline is effected by the pressure generated by the pump 4 at the pump outlet.

Regulējot sūkņa 4 produktivitāti atbilstoši kameras 1 piepildīšanas ātrumam, var panākt līdzsvaru starp sapropeļa iesūkšanas apjomu kamerā 1 un apjomu, kādā sapropeli pārsūknē sūknis 4. Pie tam, jo mazāka ir sapropeļa viskozitāte un jo lielāks ir izstrādes dziļums, jo augstāks 4 ražīgums.By adjusting the productivity of the pump 4 according to the filling rate of the chamber 1, a balance can be struck between the amount of sapropel aspirated into the chamber 1 and the amount of sapropel pumped by the pump 4. In addition,

Aizvadītājelements 3, kas ir izveidots spiediencauruļvada formā, ir aprīkots ar pretvārstu 10 un izslēdz sapropeļa atpakaļ plūšanu no spiediena cauruļvada uz sūkni 4 gadījumā, ja sūknis tiek apturēts ierīces pacelšanas un remonta dēļ.The discharge member 3, in the form of a pressure pipe, is provided with a non-return valve 10 and prevents the sapropel from flowing back from the pressure pipe to the pump 4 in the event that the pump is stopped due to lifting and repair of the device.

Kameru 1 un 8 operatīvai apkalpošanai kameras dibens 6 un sieniņas var būt aprīkotas ar hermētiskiem kontroles skatlodziņiem, kas ļauj, piem., inspicēt kameras, veikt nostādinātajā 16 tīrīšanu no lielākiem uzkrājumiem, kā arī pārbaudīt sūkņa 4 mezglus darba stāvoklī, savienotāj kabeļus, ja ierīce ir ar elektrisku piedziņu, un hidrauliskās šļūtenes, jja ierīce ir ar hidraulisku piedziņu.For operative servicing of chambers 1 and 8, the chamber bottom 6 and walls may be provided with airtight control windows allowing, for example, inspection of the chambers, cleaning of the stored 16 from a larger stock, and inspection of pump 4 assemblies in working condition is electrically driven and hydraulic hoses if the device is hydraulically driven.

Sakarā ar to, ka sūknim 4 nav jāstrādā, lai dūņas iesūktu tieši, tā kā dūņu struktūra ir izjaukta, to ievadot kamerā 1, sūknis 4 veic plūstošu iežu, kam struktūras režģis ir nojaukts, iesūkšanu pie neliela spiediena no kameras 1 caur izvades elementu, kas būtiski atvieglo sūkņa darba apstākļus un ļauj nodrošināt tā darbībai nepieciešamo jaudu tikai tik lielu, cik ir nepieciešams nogulu iedevei spiediena cauruļvadā.Because pump 4 does not have to work to suck the sludge directly, since the sludge structure is disrupted when it is introduced into chamber 1, pump 4 sucks fluid rock with the structure grid disassembled through a small pressure through the outlet member, which greatly simplifies the pump's operating conditions and allows it to operate only at the power required to deliver sediment to the pressure pipeline.
