RU67916U1 - CAMERA CAMERA - Google Patents

Abstract

The utility model relates to the production of building products and structures, in particular, to the heat treatment of concrete.

The utility model is aimed at reducing the material consumption of the lid and walls of the chamber, improving and simplifying the sealing between them, eliminating the need to remove the lid with a crane and positioning it on the premises of the workshop, as well as eliminating the destruction of walls when it is laid on the camera.

The steaming chamber consists of a floor, walls, a lid, a sealing device between the lid and the walls, ladders and a coolant supply system.

New in the chamber is that instead of a heavy iron cover, an awning is used, and instead of channels filled with sand or water, which serve to seal the chamber, sealing pipes are used that are laid along the outer edge of the walls around the entire perimeter of the chamber. The awning from three sides has devices for fixing it by the mounts mounted on three sides of the camera. The fourth side of the tent is attached to the pipe on which it is wound into a roll. The opposite side of the awning is fixed to the camera wall stationary.

Rolling the roll and fixing the awning behind the fasteners, the camera is closed, and the pipe on which the awning was wound is left to hang along the wall. Sealing is achieved due to the tight fit of the tent to the sealing pipes. Unfastening the tent, and rolling it into a roll, the camera is opened. In this case, the awning rolled up in a roll is left on the camera along the wall on which it is fixed permanently.

Awning can be made of tarpaulin, insulated tarpaulin or synthetic heat and moisture insulating material.

The absence of a heavy iron cover that destroys the wall when it is placed on the camera allows the use of doors, which reduces the complexity of the work and makes them safer.

For heat treatment of high products, it becomes possible to use a chamber with an increased height of walls and gangways, and instead of doors, install gates up to the upper cut of the chamber walls. Sealing pipes should be laid along the upper outer edge of each of the gate leaves. Enter high items into the chamber and take out of it through the gate. This eliminates the need for deepening the camera.

A light cover made of awning allows you to use lightweight metal structures covered with heat-moisture-insulating material or a double layer of tarpaulin as walls.

When changing the range of products, sometimes there is a need to change the size of the camera in a short time. This can be done without destroying the walls, if they are assembled from light heat-moisture-insulating shield modules. In this case, the installation and dismantling of the camera will be much easier.

Description

Technical field

The utility model relates to the production of building products and structures, in particular, to the heat treatment of concrete.

State of the art

Known steaming chamber of periodic action pit type fully or partially buried in the floor or floor [1]. Its main elements are: floor, walls, a sealing device between the lid and the walls of the chamber, a removable lid, ladders for servicing the chamber and a system for supplying a coolant (steam-air mixture, humidified air or, simply, warm air) [2]. To service the floor camera along its outer perimeter at a certain height from the floor, running ladders are installed. Walls are made of concrete or expanded clay concrete blocks. The cover is a flat welded metal structure, sheathed on both sides with metal sheets, between which mineral wool is laid. Prevention of coolant leakage between the cover and the chamber walls is achieved by using a hydraulic or sand shutter. Such a shutter is formed by channels filled with water or sand and installed on the upper cut of the chamber walls.

Sealing is carried out when lowering the lid, along the perimeter of which ribs are welded.

The disadvantages of this camera are:

- the presence of a metal-consuming, expensive and bulky cover;

- the need for crane operations to remove and lay the lid (distraction of the crane from other works, energy costs);

- it is necessary to have a large free area in the workshop for laying the cover;

- when laying a heavy metal cover on the camera, it hits the channels. This leads to the destruction of the walls of the chamber. Therefore, the installation of doors, and especially gates, in such a chamber is impossible and, therefore, the walls are made of heavy concrete or high-strength expanded clay concrete;

- since the height of the workshop does not allow high items to be tapped into the floor chamber, a need arises to deepen the chamber, which is not always possible;

- the absence of doors or gates in the cell creates additional difficulties and inconveniences for workers.

Utility Model Disclosure

The objective of the utility model is to reduce the material consumption and cost of the lid and walls of the chamber, improve and simplify sealing between them, eliminate the need to remove the cover with a crane and place it on the workshop floor, as well as eliminate the destruction of walls when it is placed on the camera and the ability to bring high items into the camera without its deepening and reducing the complexity of the work.

The solution to this problem is achieved:

Replaceable heavy metal camera cover with awning. Prevention of coolant leakage between the tent and the chamber walls is achieved by tight fit of the tent material to the sealing pipes laid along the outer perimeter of the upper cut of the chamber walls. An awning from three sides is attached to the mounts installed on the outside of the three walls, in the upper part, with a certain step. The fourth side of the tent is attached to the pipe hanging horizontally along the outer side of the fourth wall in its upper part. At the ends of the hanging pipe, discs are installed that limit the possible displacement of the tent along the pipe when the tent is screwed onto it when the chamber is opened.

When the camera is opened, the awning is screwed onto a pipe, which is manually rolled over the discs through the sealing pipes laid on the upper cut of the chamber walls when sequentially removing the awning from the mounts until a longitudinal wall is reached, on which one side of the awning is fixed, and the awning, wound into a roll, is left above her. When closing, the roll is rolled manually in the opposite direction by sequentially securing the tent to the mounts. In this case, the tent is tensioned in the direction of rolling the roll by periodically moving the roll in the rolling direction without rotation. Awning tension in the direction perpendicular to rolling is carried out by pulling up the awning immediately before fixing it.

Significant differences from the prototype are:

- the implementation of the cover in the form of an awning of light material having a significantly lower weight and cost than the metal cover in the prototype;

- the lack of load on the walls due to the low weight of the tent can significantly reduce the material consumption of the walls, applying various

combinations of light heat-insulating materials with light metal structures;

- the absence of impacts of the lid on the wall when closing the chamber eliminates the destruction of the walls and allows the use of doors or gates in them;

- the use of doors or gates in the wall of the chamber reduces labor costs and delivers ease of use;

- to prevent leakage of coolant between the tent and the walls of the chamber, it is not necessary to use additional substances, such as water or sand in the hydro- (sand) shutter between the cover and the walls, as in the prototype. There is also no need to monitor the status of these substances. Prevention of coolant leakage between the tent and the chamber walls is achieved by tight fit of the tent material to the pipes laid along the outer perimeter of the upper cut of the chamber walls, due to their bending by the tent material;

- for heat treatment of high products, it becomes possible to use a camera with an increased height of walls and gangways, with gates whose sashes reach the upper cut of the walls, and along the upper edges of which there are pipes for a tight fit of the tent. Such gates allow you to enter and carry through them high items into and out of the chamber without deepening the chamber. In the prototype, the camera must be buried, since the height of the workshop does not allow the transfer of tall products through high walls;

- the property of the awning material being twisted into a roll makes it possible to apply a camera opening-closing method in which the awning twisted into a roll remains on the camera, unlike the prototype, where a place is needed in the workshop for the location of the cover removed from the camera;

- the exception of crane operations allows you to not distract the crane from the work in the shop and save electricity.

Thus, this set of features can be considered significant, since the distinctive features determine the achievement of an undoubted economic effect.

Utility Model Implementation

The steaming chamber consists of walls 1 made of foam concrete blocks, sealing tubes 2, fixed along the outer perimeter of the upper cut of walls 1 and serving to tightly fit the awning, insulated floor 3, awning 4 made of insulated tarpaulin or just tarpaulin, pipe 5 , to which one side is attached to the awning 4, restrictive disks 6 mounted on the edges of the pipe 5, which do not allow the tarpaulin to move along the pipe 5 when it is wound on it, ladders 7 for servicing the camera, door or gate 8 and mounts 9, lenny in one line on the outer side of the rear and side walls, in their upper part at a distance of 0.4-0.5 m from the upper cut of the chamber walls with an interval of 0.5-1 m.

The awning 4 is attached on one side to the pipe 5, and along the other three sides of the awning at a distance of 5 cm from its edges are mounted eyelets 11, through which they are threaded and tied to the edges of the awning of the halyard 10.

Mounts 9 are made of smooth rods in the form of the letter "k", and when attaching an awning to them, interact with the halyards 10.

Eyelets relative to the mounts are as follows. On the back wall - directly above the mount, on the side walls with an offset towards the back wall. This is necessary so that the halyard, being located obliquely, maintains the tension of the tent, both in the direction of rolling the roll and in the direction perpendicular to it.

Covering the camera with an awning is as follows. With the chamber fully open, the awning material rolled up is located above the rear wall of the chamber. At the same time, one edge of the tent is fixed on the pipe 5 located inside the roll, and the other is fixedly fixed to the upper part of the rear wall. Two workers, located at different ends of the pipe 5, walking along the ramps 7, roll the roll through the sealing pipes 2, rotating it over the restrictive discs 6. Rolling the roll a certain distance, stretch the awning in the direction of rolling the roll, pushing it without rotation. Then fix several files 11 on each side of the camera for mounting 9, pre-pulling the tent in the direction perpendicular to rolling. The halyard is fixed for fastening in one circular motion around it. At the same time, the halych, pinched in the wedge-shaped mounting openings, is securely fixed in them. Rolling, thus, the roll and fixing the awning, they reach the front wall, where the roll is completely rolled out and, lowering the pipe 5, with the edge of the awning 4 fixed on it, leave it hanging along the front wall. Hanging pipe 5 provides a snug fit of the awning 4 to the sealing pipe 2, located above the front wall, and creates an additional tension of the awning 4.

Closing the camera is carried out in the reverse order. Several files 10 are fastened from the fasteners 9 on the side walls of the chamber, starting from the hanging pipe 5. Then, the pipe 5 is lifted onto the sealing pipes 2 and the pipe 5 is rolled along them, winding the detached part of the tent 4. The cycle is repeated several times until the camera is fully opened. The formed roll is left lying over the back wall of the chamber.

The closing time of the camera is 2 minutes, the same is the opening time. The size of the chamber is 6.5 × 10 m. The provision in the center of the chamber with its average tension is 100-250 mm.

The awning can be made of tarpaulin, a double layer of tarpaulin, insulated tarpaulin or synthetic heat and moisture insulating materials.

The difference in the cost of the iron cover and tarpaulin is at least 100 thousand rubles. From the area in the workshop, freed from the iron cover, additionally removed products worth 3520 rubles. per day or 78,410 rubles. per month. The crane is freed from removing and installing the cover and does other work in the workshop. Savings also arise due to reduced labor costs and increased work safety.
