Наиболее близким к изобретению по технической сущности является барабанный грохот, включающий основание, раму, установленную на основание с помощью амортизаторов, загрузочный и разгрузочный 20 узлы, барабан конической формы с просеивающей поверхностью, установленный на раму и связанный с приводом. Барабан снабжен опорным кольцом с выступами, а под кольцом установлен взаимодействующий с ним опорный элемент [2].Closest to the invention in technical essence is a drum screen, including a base, a frame mounted on the base using shock absorbers, loading and unloading 20 nodes, a conical shape drum with a screening surface mounted on the frame and connected to the drive. The drum is equipped with a support ring with protrusions, and a supporting element interacting with it is installed under the ring [2].

Однако эффективность разделения на нем невысокая так как конструкция его материала подвергается воздействию только вибрационных колебаний.However, the separation efficiency on it is low since the design of its material is exposed only to vibrational vibrations.

Целью изобретения является повышение эффективности разделения.The aim of the invention is to increase the separation efficiency.

Поставленная цель достигается тем, что опорное кольцо с выступами размещено на боковой поверхности барабана. Кроме того, просеивающая поверхность барабана выполнена секционной, а опорный элемент имеет стойки с установленными на них роликами, выполненными из резины.This goal is achieved in that the support ring with protrusions is placed on the side surface of the drum. In addition, the screening surface of the drum is made sectional, and the supporting element has racks with rollers mounted on them made of rubber.

На фиг. 1 изображен барабанный грохот, общий вид; на фиг. 2 — разрез А—А на фиг. 1.In FIG. 1 shows a drum screen, general view; in FIG. 2 — section A — A in FIG. 1.

Грохот состоит из конического барабана 1, сетки 2, опорного кольца 3 с выступами, стойки 4, ролика 5, кардана 6, силового привода с муфтой 7, редуктора 8, электродвигателя 9, рамы 10, распределительного желоба 11, амортизаторов 12.The screen consists of a conical drum 1, mesh 2, a support ring 3 with protrusions, a rack 4, a roller 5, a cardan 6, a power drive with a coupling 7, a gearbox 8, an electric motor 9, a frame 10, a distribution chute 11, shock absorbers 12.

Грохот работает следующим образом.The roar works as follows.

Вращательное движение от силового привода через кардан 6 передается на сепарирующий барабан 1. При вращении барабана 1 опорное кольцо 3 с выступами, перекатываясь по роликам 5, ракачивая, встря- ⁵хивает его. От этого вибрирует рама 10 и сепарирующий барабан 1. В результате барабан имеет вращательное движение и получает раскачивающее, встряхивающее и вибрационное колебания. Их численная величи- ₎₀на зависит от числа оборотов барабана 1, количества и высоты выступов опорного кольца 3.The rotational movement from the power drive through the cardan 6 is transmitted to the separating drum 1. When the drum 1 rotates, the support ring 3 with protrusions, rolling along the rollers 5, swelling, shaking it ⁵ . From this, the frame 10 and the separating drum 1 vibrate. As a result, the drum has a rotational movement and receives a swinging, shaking and vibrational vibration. Their numerical value - _{) 0} on depends on the number of revolutions of the drum 1, the number and height of the protrusions of the support ring 3.

Буровой раствор по распределительному желобу 11, попадая во внутрь барабана 1, стекает через сетку 2 в корыто вибрирую- 15 щей рамы 10, а отделившийся шлам полувинтовыми движениями удаляется из него в шламосборную емкость.The drilling fluid flows through the distribution channel 11 into the drum 1 and flows through the net 2 into the trough of the vibrating frame 10, and the separated cuttings are removed by half-screw movements into the collection tank.

В результате фактически свободной установки барабана очистка бурового раствора ₂₀происходит под влиянием вращательного, раскачивающего, встряхивающего и вибрационного движений, поэтому структура бурового раствора больше разрушается и тем самым облегчается его прохождение через ячейки сетки; непрерывно очищаются ячей- 25 ки сетки от закупоривания; буровой раствор непрерывно движется и попадает на очищенную поверхность сетки, и интенсивно удаляется шлам к выходу полувинтовыми движениями. Все это значительно повышает эффективность очистки бурового раствора от шлама.As a result of the virtually free installation of the drum, the cleaning of the drilling fluid ₂₀ occurs under the influence of rotational, swinging, shaking and vibrational movements, therefore, the structure of the drilling fluid is more destroyed and thereby its passage through the mesh cells is facilitated; 25 mesh cells are continuously cleaned from clogging; the drilling fluid moves continuously and enters the cleaned surface of the mesh, and the cuttings are intensively removed to the exit by half-screw movements. All this significantly increases the efficiency of cleaning mud from sludge.

Выполнение просеивающей поверхности секционной позволяет уменьшить время замены изношенных участков просеивающей поверхности и более экономно расходовать материал, из которого она выполняется. Выполнение опорных роликов из резины позволяет уменьшить шумовыделение.The implementation of the screening surface section allows you to reduce the time of replacement of worn sections of the screening surface and more economical to expend the material from which it is made. The implementation of the support rollers made of rubber can reduce noise.

Claims

(54) DRUMSTERME OF THE INVENTION The invention relates to the drilling of oil wells, namely, devices for drilling mud, and can be used in the oil and gas industry, as well as in the mining, construction and other industries. A vibrating screen for cleaning drilling mud is known, which includes a base on which a spring-loaded frame with a grid, a vibrator, a loading and unloading unit is installed. The tensioning net on the drums, allowing them to wind up as they wear out. The disadvantage of it is that the cleaning of drilling fluids on it is based on only one vibration movement of the separating unit. The closest to the invention to the technical essence is a drum screen comprising a base, a frame mounted on the base with shock absorbers, loading and unloading units, a drum of conical shape with a screening surface mounted on the frame and connected to the drive. The drum is provided with a support ring with protrusions, and below the RING there is a supporting element 2 interacting with it. However, the separation efficiency on it is low because the design of its material is affected only by vibrational vibrations. The aim of the invention is to increase the separation efficiency. The goal is achieved by the fact that the support ring with protrusions is placed on the side surface of the drum. In addition, the screening surface of the drum is made sectional, and the supporting element has racks with rollers mounted on them made of rubber. FIG. 1 shows a drum screen, a general view; in fig. 2 shows section A-A in FIG. 1. The screen consists of a conical drum 1, grid 2, support ring 3 with protrusions, pillars 4, roller 5, cardan 6, power drive with clutch 7, gearbox 8, electric motor 9, frame 10, distribution chute 11, shock absorbers 12. Screen works as follows. The rotational movement from the power drive through the cardan 6 is transmitted to the separating drum 1. When the drum 1 rotates, the support ring 3 with its protrusions, rolling over the rollers 5, is gentle and shakes it. From this, the frame 10 and the separating drum 1 vibrate. As a result, the drum has a rotational movement and receives swinging, shaking and vibrating vibrations. Their numerical value depends on the number of revolutions of the drum 1, the number and height of the stupas of the reference drilling mud on the distribution chute 11 into the inside of the drum 1, flows through the grid 2 into the trough of the vibrating frame half of the screws of the moving shaft is removed from it into the sludge tank: As a result of the virtually free installation of the drum, the cleaning of the drilling fluid occurs under the influence of rotational, swinging, shaking and vibrational movements, therefore the structure of GHGHGsHerH,; o1 ;; d: yi: and grid; mesh closures are continuously cleaned from clogging; the drilling fluid continuously moves and falls on the cleaned surface of the screen, and is intensively removed from the gaps to the exit with semi-screw movements. All this greatly improves the efficiency of cleaning mud from the mud. The implementation of the sectional screening surface makes it possible to reduce the replacement time of the worn-out sections of the screening surface and to more economically consume the material from which it is made. Making the support rollers of rubber reduces noise emission. Claim 1. Drum screen, including wasps,.
