Description

Shaft furnace for ceramic products

The utility model relates to the field of the industry of construction materials, in particular, to technological equipment for firing ceramic wall materials.

Ceramic furnaces for ceramic molds are known (see W Tnerhriclc, V 8 .Nb, p 157-160, London, 1992).

The well-known ceramic furnace for ceramic products consists of a through vertical firing channel, a cage elevator, a support clamp for cage products in the form of bars, which pass through through gaps between the products, and carts for removing and transporting the package with a supporting surface in the form of bars located with offset relative to the fixing bars. The squatting of articles in the form of a column of a quadrate cross-section fills the through calcining channel. Raw products enter the channel from above and gradually lower down, passing sequentially through the heating, calcining and cooling zone air. Air enters from the bottom of the channel, glows from the cooling products, participates in combustion in the middle part of the channel, in In the form of kiln weights, it rises, gives off heat to them for raw products and is released into the atmosphere.

Raw products are lifted onto the furnace to the upper inlet section of the calcining channel and stacked on the calcined cage located on the bars of the retainer. At the same time as the products are stacked, solid fuel is poured into the bag. The trolley rolls onto the lift, the lift with the trolley through the gaps between the bars raises the charge, the bars

disadvantages.

The furnace loading zone with products at the furnace inlet section is under

exposure to flue gas emissions. In such negative conditions

solid fuel is also backfilled

To load the furnace, the products go up, for which it is spent

a certain amount of energy.

At the same time, when unloading the furnace during the separation of each burnt package

products to work on raising the entire cadd products

Thus, a double amount of energy is spent on lifting products.

The purpose of the utility model is to eliminate these drawbacks by laying products in firing bags and filling top.p (willow in bags below the zone of exhaust gas emissions and balancing the lowered and raised products.

This goal is achieved by the fact that in the proposed shaft furnace for ceramic products, it consists of a through vertical firing channel, a cage lift, a support cage support in the form passing through the through gaps between the products, and those for removal and transportation of the product package, the cage elevator is made in the form of paired vertical scissors, the lower external ends of which have rigid articulated supports at the same level, the internal lower ends of the scissors are equipped with peak supports, connected between each other adjustable rigid traction and have a single drive of horizontal movement, the outer upper scissor sheaths are connected via horizontal to the platforms for receiving trolleys, and the roller supports of the platforms are located on the inner upper ends of the scissors, the lower and upper ends of the scissors moving horizontally, the length of the scissor arms provides the lifting stroke the areas of the bolge of the height of the package, the island of the areas is located under the firing channel, and above the long platform there is a latch for production of goods.

The proposed shaft furnace is equipped with a grab type gripper located at the top of the furnace inlet end, which, in addition to the lifting and clamping, also has horizontal movement between the two platforms.

Technical description

A shaft kiln for ceramic products (Fig. 1) consists of a through kertikapny roasting kanyanapya 1 subframe 7. c. I fired products, a column of 4 sfy products, supporting clamps in the form of bars 5, pass through the sknoznye gaps between editions. tedezhk-6 for the removal and transportation of a package of products 7 and grab grab 8.

The LIFT OF SYADK 7 is made R in the form of SPARED vertical SCISSORS 11,

consisting of levers 9 and 10. For levers 9, the lower ends are supported by fixed and hinged supports 11, the upper ends are provided with rollers 17 At the levers 10, the lower ends are equipped with rollers 13, and the upper ends are removed from the horizon through the hinged support 17. ., based on rollers 12. The lower ends of the levers 10 are connected by a rigid adjustable rod 17 and have a single drive horizontal reciprocating movement (not shown). The ratio of the shoulders of the levers 9 and 10 provides a strictly vertical horizontal descent 14 and 15 with the amount of lifting platforms 14 and 15 more than the height of the packages of products 7 and a stable position of the seedling 1 and column 4 due to the fact that the position of the rollers 12 in its highest position does not go beyond the center package severity 7.

Ceramic products are stacked in a bag 7 on a trolley 6 located outside the furnace zone. When stacking a bag 7 in the gaps between the products, solid fuel packaged in paper or other containers is laid. During the initial filling of the furnace channel 1, the carts 6 with packages 7 are rolled onto one of the platforms 14 or 15, which is in the lowered position, when turned on, when lowering the lower contacts of the levers 10 move under the receiver, they move in the same direction, and the platforms 14 and 15 move in opposite directions - one nya lift another nya lowering The initial lifting of platforms 14 and 15 is carried out with trolleys 6 and packages 7 with extended bars 5 and stays pressed when the excess of package 7 over the bars 5. The bars 5 are inserted between the bars of the cart 6. When lowering panying ploti.adok 14 and 15 the trolley 6 is separated from the remaining AEs pyaketa 7 5 bars.

The next lifted packages 7 pass through the top layer of the products of the bars 5, raise the previously raised packages 7, stop and allow the bars to be removed 5 The bags 7 are completed, the bars 5 are inserted into the crate, and thus the formation of a full cage 3 in the oven canapa 1 occurs by feeding the packages 7 raw products from bottom to top A similar pile accumulates a column of raw products 4 of the same height as cage 3, or as less as the strength of raw products allows. During the operating cycle of the furnace with firing products in channel 1, the platform 15 work only the lowering of the packages 7 takes away, and the flames 14 only on their raising. At the same time, for almost the entire time, lifting the pillar 4 platform 14 Device

Operating principle.

cage 3 is located on the site 15 and, thus, the loaded site 14 and 15 are balanced.

With a short-term approach to the extreme upper positions of platforms 14 and 15, when one of the platforms is not loaded, the levers 9 and 10 are shifted to a vertical position, resulting in a significant increase in the podism force of platforms 14 and 15 without increasing the drive force of the lift 2.

The initial position of the grab grab is 8 nakh. at a given height above a column of 4 packages of raw products. When lifting column 4, the upper package transfers the gripper 8 to the clamping position, the gripper 8 with the product package rises to the upper position, moves the package over the kiln furnace 1 and lowers the package to the cradle 3. The gripper 8 is automatically fixed in the open position and returns to its original position above post 4.

Thanks to the proposed design of the inventive shaft furnace, in contrast to the prototype, the energy consumption for lifting products when they are fired is significantly reduced and it is possible to put the products in a bag for burning and lay solid fuel in a bag outside the furnace, in an area free from the effects of furnace gases .
