Description
Technical Field
The invention relates to the technical field of material detection equipment, in particular to a building material formaldehyde detection device.
Background
Formaldehyde is a carcinogenic substance which is commonly existed in building materials, so after the building is built, ventilation needs to be carried out for a period of time indoors, so that the formaldehyde in the building materials can be conveniently dissipated, the content of the indoor formaldehyde is reduced, and the building material is beneficial to the health of people. However, some building materials release formaldehyde for a longer period of time due to the higher formaldehyde content, and thus, a distinction needs to be made between such materials. The distinguishing method is mainly carried out by formaldehyde detection equipment, and the formaldehyde release condition of the material is obtained by detection. In the building material, the formaldehyde content of the artificial board is more prominent, so that the formaldehyde content detection of the board is particularly important. When detecting the formaldehyde emission of the board, the formaldehyde needs to be collected first, and then the weight of the formaldehyde is measured.
In the existing detection of the plate, the main method is a climate box method, namely, a plate test piece with the surface area of 1 square meter is placed in a climate box with the temperature, the relative humidity, the air flow rate and the air replacement rate controlled at certain values, and the air in the box is periodically extracted to detect the formaldehyde concentration until the formaldehyde concentration in the box reaches a balanced state, so that the formaldehyde emission of the plate is obtained. In order to make the formaldehyde distribute evenly in the detection case, can set up the mechanism of disturbance air in the detection case, simultaneously, in order to make things convenient for the formaldehyde on panel surface to be can quick diffusion, still need set up the mechanism that is used for producing the air current for the panel surface, then, so, the mechanism in the detection case is more, and the mechanism can produce vibration and noise when the operation, when a plurality of mechanisms all work, whole detection device's vibration and noise will be great to be unfavorable for the detection personnel to work in such detection ring border.
Disclosure of Invention
The invention provides a building material formaldehyde detection device, which aims to solve the problem that in the prior art, the formaldehyde detection box has more mechanisms, so that the vibration and the noise are higher.
The basic scheme of the invention is as follows: building material formaldehyde detection device, including the detection case, the inside of detection case rotates and is connected with along horizontal plane pivoted carousel, sets firmly two fixed establishment that are used for vertical fixed panel on the carousel, and two fixed establishment crisscross settings are central symmetry with the axis of revolution of carousel, be equipped with the sealing member that is used for sealing the panel edge on the fixed establishment, the one end that fixed establishment is close to the carousel axis is equipped with the aviation baffle of V font, aviation baffle and carousel fixed connection, be equipped with on the detection case and be used for driving carousel pivoted actuating mechanism.
And the turntable is used for driving the fixing mechanism to rotate. And a fixing mechanism is arranged for fixing the plate for detection. Sealing elements are provided for sealing the edges of the board so that formaldehyde is released mainly from the front and back sides of the board. And the air deflector is arranged and used for guiding the airflow on one side opposite to the fixing mechanism to the other side of the fixing mechanism.
Compared with the prior art, the scheme has the advantages that: when in detection, the two plates are respectively fixed on the fixing mechanism, and then the rotary table is utilized to drive the fixing mechanism to rotate, so that the plates push the gas in the detection box to flow, meanwhile, a part of gas flows from the windward side of one end of the plate far away from the axis of the rotating disk along the side surface of the plate to one end of the plate close to the axis of the rotating disk, and flows to the other side of the plate under the action of the air deflector, the leeward surface of one end of the plate far away from the axis of the rotary disc can generate an aerodynamic shadow region under the action of the rotation of the plate, the aerodynamic shadow region belongs to a negative pressure region, and one end of the plate close to the axis of the rotary disc can form a positive pressure area under the action of the air deflector, so that the air on the side surface of the plate flows from the positive pressure area to the negative pressure area and forms airflow, and then the side of the plate is enabled to flow through by air flow, so that formaldehyde released by the plate can be conveniently and rapidly diffused into the air in the detection box. Rotate the air that promotes the detection case through the panel that utilizes needs to detect and flow, produce the air current that flows on the surface of panel simultaneously, and then be convenient for formaldehyde carry out even diffusion in the detection case, need not to set up the mechanism that is used for disturbing the air in the detection case alone and produce the mechanism of air current on the panel surface, and then simplified whole detection device's structure to vibration and noise have been reduced.
Further, the fixing mechanism comprises a rectangular support, two vertical clamping blocks and two horizontal clamping blocks are arranged on the support, one vertical clamping block close to the axis of the rotary disc is connected with the support in a sliding mode along the horizontal direction, the horizontal clamping block located on the upper portion of the support is connected with the support in a sliding mode along the vertical direction, and the sealing elements are fixedly arranged on the vertical clamping blocks and the horizontal clamping blocks. Through setting up vertical fixture block and horizontal fixture block for it is fixed to carry out the centre gripping to the four sides of panel. With the sealing member setting on the fixture block, conveniently just make the sealing member seal to the edge of panel when panel carries out the centre gripping fixed, need not to operate the sealing member alone.
Furthermore, the sealing element is a flexible air bag, and the sealing element on the transverse clamping block is communicated with the sealing element on the vertical clamping block far away from the axis of the rotary disc. Set the sealing member to flexible gasbag, make the sealing member can take place certain deformation along with the edge of panel to the better edge laminating of panel, thereby guarantee sealed effect. After the sealing element on the transverse clamping block is communicated with the sealing element on the vertical clamping block far away from the axis of the rotary disc, the plate extrudes the sealing element on the vertical clamping block far away from the axis of the rotary disc under the action of centrifugal force, so that gas in the sealing element on the vertical clamping block is extruded towards the sealing element on the transverse clamping block, and the sealing element on the transverse clamping block is increased to seal the edge of the plate, and the sealing effect is enhanced.
Further, the turntable is rotatably connected with the bottom of the detection box. The rotary table is arranged at the bottom of the detection box, so that the gravity center of the detection box is favorably reduced, the stability of the detection box is increased, and the vibration generated when the rotary table rotates is reduced.
Further, the driving mechanism is a servo motor. The servo motor is arranged to drive the rotary table to rotate, so that the rotating speed of the rotary table can be conveniently controlled.
Furthermore, an electric heating wire is embedded on the side wall of the detection box. Through set up electric heating wire on the lateral wall at the detection case, conveniently heat the air in the detection case to reach the temperature requirement when detecting, simultaneously, because electric heating wire sets up on the lateral wall of detection case, so the temperature of lateral wall is than higher, has avoided the phenomenon of dewfall to take place on the lateral wall.
