The utility model provides an automatic instrument device. The automatic instrument device, including the box, the side surface of box has the closed door of loose joint, the inside fixed sleeve of box has the partition frame, the front surface fixed mounting of box inner wall has the instrument body, the side surface fixed sleeve of box has the data wire. The utility model provides an automatic instrument device has through setting instrument body, when in the installation fixed of instrument body, the stretch clamping piece, so that the clamping piece can drive the spring to compress, at this time a plurality of data wire sleeve joint in the inside of clamping piece and loosen clamping piece, so that the spring can drive the clamping piece tightly extrude and hold in the outside of data wire, and then reaches a plurality of data wire clamping fixed effect simultaneously, thereby reaches a plurality of wire separate fixed effect, so that avoid the problem that the data wire unification fixed happens the confusion, thereby has brought the convenience for the maintenance use of instrument.

The invention provides black paste for labor protection gloves and a preparation method of the black paste, and belongs to the technical field of preparation of labor protection appliances, an anionic surfactant in the black paste has good permeability, and can accelerate the exchange speed of a solvent and water in the black paste and improve the brightness; the added dispersing agent can avoid flocculation of carbon black particles, stability of the color paste is improved, in addition, the amine value of the color paste is low, and the viscosity cannot be affected under the high-temperature condition; the adopted hydroxyl acrylic acid modified polyurethane contains COOH, OH, benzene ring and other pigment affinity groups, has the advantage of high gloss, and also has certain dispersion and viscosity reduction functions. The black paste provided by the invention is wide in raw material source, low in price, simple in production process and low in cost, and the prepared black paste has the characteristics of high blackness, high brightness, high solid content, low viscosity, low odor and good wear resistance, and has good application prospects and popularization values.

The utility model relates to sewage treatment technical field, and disclose sewage treatment equipment, including septic tank main part, the feed pipe and the overflow pipe of setting respectively at septic tank main part both sides and the exhaust hole of setting at septic tank main part top, the inside fixed coupling of exhaust hole has the exhaust pipe, the utility model discloses a wind inlet pipe, air outlet pipe and air passage are set, when meeting windy weather time, the outside airflow flows in the wind inlet pipe, air passage and air outlet pipe inside, owing to'venturi effect' can accelerate the air flow speed from below to upwards in the exhaust pipe inside, the stench produced in septic tank main part can be discharged more quickly, reduced the accumulation time of stench in septic tank main part, and the efficient stench discharge is helpful to keep the relative cleanness of the air in the septic tank main part pool inside, and this design prevents the stench reflux, prevents the indoor environment from being contaminated, creates a more healthy, comfortable living environment for the residents.

This utility model relates to the field of food processing equipment and discloses an automatic pressure relief device for an empty cake baking box. It includes: a baking box body, with an inner baking liner inside; a door rotatably connected to one side of the outer wall of the baking box near the inner baking liner; and heating elements and baking racks installed inside the inner baking liner. It also includes a pressure relief mechanism, comprising an exhaust pipe connected to the internal space of the inner baking liner and an intake pipe connected to the outside air, each equipped with a first / second solenoid valve and an exhaust fan at the outlet. The control system uses a timing unit and a temperature sensor for coordinated control. This utility model achieves precise, unmanned pressure relief operation, replacing the traditional manual door opening method. It can automatically exhaust and cool according to a preset program, solving the problem of cakes bursting due to inaccurate manual operation, thus ensuring baking quality and significantly improving product yield and stability.

The utility model relates to the technical field of electro-fused white corundum cooling and dust removal, and discloses an electro-fused white corundum cooling and dust removal device which comprises a cooling and dust removal mechanism and a bag-type dust remover, the cooling and dust removal mechanism comprises a cooling and dust removal box, a cooling fan and a mounting water pipe, and a top cover is fixedly mounted at the top of the cooling and dust removal box. And a plurality of mounting water pipes are fixedly mounted on the inner walls of the two sides of the top cover. Through the arrangement of a mounting water pipe, a water spraying head and the like, water mist can make more uniform contact with materials, the heat exchange speed is increased, the material cooling time is effectively shortened, the production efficiency is improved, through the arrangement of a cooling dust removal box, a cooling fan and the like, airflow is guided through a connecting air pipe in a matched mode, external cold air can be rapidly sucked into the box, and the cooling efficiency is improved. Good air convection is formed, material cooling is accelerated, the stability and high efficiency of the cooling process are guaranteed, external dust and impurities are prevented from entering the cooling dust removal box, and impurities are prevented from being doped in the fused white corundum.
