Description

Oven for civil engineering experiments

Technical Field

The invention belongs to the field of civil engineering, and particularly relates to an oven for civil engineering experiments.

Background

In various experimental researches of civil engineering, asphalt or aggregate is often heated by an oven, and although protective tools such as gloves and experimental clothes are worn during experiments, scalding is easily caused along with accumulation of experiment times, particularly when materials in a deeper part of the oven are taken out. And in the process of taking out the materials, because the oven door is opened, a large amount of heat is emitted from the oven in a short time, the electricity consumption of the oven is increased by reheating, and time is consumed by waiting for the oven to reach the target temperature.

Disclosure of Invention

The invention aims to provide an oven for civil engineering experiments.

The technical solution for realizing the purpose of the invention is as follows: the utility model provides an oven for civil engineering experiments, the oven is inside to be divided into two-layer about through the stainless steel division board, the relative both sides of oven are equipped with two oven doors respectively, and two oven doors of every side are setting from top to bottom, and the boundary line setting of the oven door on upper portion and the oven door of lower part is in stainless steel division board department.

Further, the device also comprises a temperature sensor, a heating pipe, a temperature regulator and a stainless steel grid plate;

a temperature regulator is arranged on the wall of the oven between the oven doors at the two sides, and a temperature sensor is arranged inside the oven;

the middle parts of the upper layer and the lower layer of the oven are respectively provided with a stainless steel grid plate for placing a sample to be heated; the inner wall surface of the oven opposite to the temperature regulator is provided with four heating pipes, and the four heating pipes correspond to four chambers divided by the partition plate and the stainless steel grid plate;

the temperature regulator is electrically connected with the temperature sensor and the heating pipe.

Furthermore, the smoke alarm is arranged on the inner wall surface of the top plate of the oven and is electrically connected with the temperature regulator.

Further, still include exhaust system, exhaust system sets up on the roof of oven, and is connected with the temperature regulator electricity.

Furthermore, a gap of 3-8cm is reserved between the stainless steel partition plate and the inner wall surface provided with the heating pipe, and the gap is used for heat exchange and exhaust of the upper layer and the lower layer of the oven.

Further, the maximum heating temperature of the heating tube should reach 300 ℃.

Furthermore, each oven door is provided with a handle, and the handle is arranged on one side close to the temperature regulator.

Furthermore, a temperature display and a switch are arranged on the temperature regulator.

Compared with the prior art, the invention has the remarkable advantages that:

when taking out the experimental materials such as asphalt, aggregate and the like from the oven, the experimental materials can be taken out from the oven door close to one side of the experimental materials, so that accidental scalding caused by the fact that hands are too deep into the oven is avoided; and the oven is divided into an upper part and a lower part, and is separated by the stainless steel partition plate, so that only one oven door needs to be opened when the experimental material is taken out, and the reduction of heat loss is facilitated.

Detailed Description

The present invention is described in further detail below with reference to the attached drawing figures.

As shown in fig. 1-4, an experimental oven comprises a box body 1, a temperature sensor 4, a smoke alarm 5, a heating pipe 6, an exhaust system 7, an oven door 2, a handle 3, a temperature regulator 8, a temperature display 9, a partition plate 10, a switch 11 and a stainless steel grid plate 12;

the temperature sensor 4 is used for monitoring the temperature in the oven and transmitting a signal to the temperature regulator 8, when the temperature reaches the target temperature, the temperature regulator 8 controls the heating pipe 6 to stop working, and when the temperature is lower than the target temperature, the temperature regulator 8 enables the heating pipe 6 to start working.

The smoke alarm 8 is used for finding smoke generated by combustion of experimental materials in the oven 1, and when the smoke is detected, the smoke alarm gives out alarm whistle to call laboratory workers to carry out fire safety inspection, so that the damage possibility and the experiment risk of experimental instruments are reduced.

Exhaust system 7 is located the top of oven for keep the inside and outside circulation of air of oven, be favorable to the steam discharge of gathering materials, make the quick drying of the gathering materials of placing, shorten the stoving time of gathering materials, reduce the electric quantity of oven work.

The working process of the invention is as follows: when the device works, the oven door 2 on one side is opened, asphalt or aggregate is placed in the oven, the switch 11 is started, the target temperature is set, and the oven door 2 is closed. When taking out the interior experimental materials of oven, should wear safety protection equipment, open one side oven door 2 nearer apart from experimental materials, avoid the arm too deep into the oven inside to cause the scald. The oven door 2 should be closed immediately after the test material is taken out, so that the oven door 2 is prevented from being in an open state for a long time.
