Abstract

The utility model belongs to catalyst manufacturing equipment technical field, it is related to a kind of dry sieve plate, it is characterised in that it is assembled by upper, middle, and lower part, and upper and lower two parts are bolted, and fix the pipeline of middle section, the pipeline of middle section is equipped with two nozzles of one-in-and-one-out；It is uniformly distributed several apertures on described upper and lower two parts.Moisture in the utility model catalyst granules can obtain rapid evaporation, the catalyst granules of especially dry floor lever of sieve tray obtains rapid draing, the problem that aqueous catalyst particle easily blocks dry head is also eliminated simultaneously, reduce labor intensity, drying efficiency is improved, the quality and yield of catalyst prod are greatly improved.

Description

A kind of dry sieve plate

Technical field

The utility model belongs to catalyst manufacturing equipment technical field, is related to a kind of for the dry of pellet type catalyst drying Dry sieve plate.

Background technology

During preparing pellet grained catalyst using infusion process, need will by dipping, washing, filtered contain Water catalyst granules is conveyed into drying machine and is dried, and common method is directly to be placed in aqueous catalyst particle to be laid at present On the vibrating machine for filtering fine-structure mesh, by the vibrating effect of vibrating machine, aqueous catalyst is imported into drying machine, there are aqueous Catalyst granules easily blocks filtering fine-structure mesh, manual cleaning and easily easily blocks drying machine to the breakage of filtering fine-structure mesh, aqueous catalyst particle Head needs the problems such as timing cleaning, causes aqueous catalyst particle except water speed is slow, drying efficiency is relatively low, manual working intensity height etc. Problem affects the yield and quality of catalyst prod.

Invention content

The purpose of this utility model is will to be easily piled up in the aqueous catalyst particle on filtering fine-structure mesh, be layed in dry sieve plate On, by the heating medium for heating in dry sieve plate, so that the water content of aqueous catalyst particle is largely removed, be aided with machinery and shake It is dynamic, so that catalyst granules is smoothly imported in drying machine and be further dried, on the one hand can solve because of aqueous catalyst particle Manual cleaning excessive caused by filtering fine-structure mesh, the cracky of strainer and frequent replacement problem are easily blocked, on the one hand can be eliminated Aqueous catalyst particle easily blocks the problem of dry head, reduces labor intensity, greatly improve catalyst prod quality and Yield.The utility model is suitable for during the filtration drying of all kinds of particle powder matter, is catalyzed especially suitable for particle powdery The filtration drying process of agent.

The utility model is achieved like this：Dry sieve plate, it is characterised in that it assembled by upper, middle, and lower part and At upper and lower two parts are bolted, and the pipeline of middle section is fixed, and the pipeline of middle section is equipped with one-in-and-one-out Two nozzles；It is uniformly distributed several apertures on described upper and lower two parts.

Usually, described upper and lower two parts are stainless steel plate, are evenly distributed with the aperture of 10 ~ 100 mesh.

The pipeline of the middle section is stainless steel tube, U-shaped arrangement.

The pipeline of the middle section is stainless steel tube, is in O-shaped arrangement.

The pipeline of the middle section is flexible coupling through two nozzles of one-in-and-one-out and external heating agent by bellows.

The utility model has following features and advantageous effect：The pipeline that heating agent passes through bellows and dry sieve plate middle layer Import and export connects, by heat transfer with exchange, make entirely to dry sieve plate skin temperature and reach 60 ~ 120 DEG C, the tide of water content Moist catalysis particle is layed on dry sieve plate, and the moisture content in catalyst granules obtains rapid evaporation, especially dry sieve plate table The catalyst granules in face obtains rapid draing, is aided with the vibration of vibrating machine, and the catalyst granules of diameter qualification obtains quickly mistake Filter is smoothly imported in drying machine and is further dried, and is solved because the aqueous more filtering fine-structure meshes that easily block of catalyst granules cause Excessive manual cleaning, strainer cracky and the problem of frequently replace, while also eliminate aqueous catalyst particle easily block it is dry The problem of dry head, reduces labor intensity, improves drying efficiency, greatly improves the quality and yield of catalyst prod.

Fig. 2 is the structural schematic diagram of the utility model embodiment 2.

Fig. 3 is the uniformly distributed schematic diagram of aperture on upper and lower two parts in embodiment.

In figure, a is stainless steel plate, and b is stainless steel tube, and c is Heating medium, and d exports for heating agent, and e is bolt.

Specific implementation mode

The utility model is further illustrated with reference to the accompanying drawings and examples, but the protection domain of this patent is not by reality Apply the limitation of example.

Following embodiment is embodiment of the present apparatus in molecular sieve catalyst drying process, is used for the system of molecular sieve catalyst Standby process.

Embodiment：Dry sieve plate, refer to the attached drawing 1-3, it is assembled by upper, middle, and lower part, and upper and lower two parts are logical Cross and be bolted, and the pipeline of middle section is fixed, the pipeline of middle section is equipped with two nozzles of one-in-and-one-out, i.e., heating agent into Mouth c and heating agent export d, are flexible coupling by bellows through two nozzles of one-in-and-one-out and external heating agent.；Described upper and lower two parts On be uniformly distributed the apertures of several 10 ~ 100 mesh.

Embodiment 1：With reference to figure 1, the upper and lower two parts of the present embodiment are stainless steel plate a, are connected by bolt c, and will be intermediate Partial pipeline is fixed, and pipeline is stainless steel tube b, U-shaped arrangement.

Embodiment 2：With reference to figure 2, the upper and lower two parts of the present embodiment are stainless steel plate a, are connected by bolt c, and will be intermediate Partial pipeline is fixed, and pipeline is stainless steel tube b, is in O-shaped arrangement.

In embodiment, dry sieve plate is placed on vibrating machine, after the heat medium pipe on dry sieve plate is connected by bellows, is beaten Heating agent pipe valve is opened, after so that heating agent is preheated to 60 ~ 120 DEG C to dry sieve plate, the wet molecular sieve Jing Guo centrifuge initial gross separation is urged Agent is layed on dry sieve plate, and the moisture content in the catalyst being layed on dry sieve plate is removed rapidly, is aided with machinery and is shaken Dynamic, particulate molecular sieve catalyst is filtered by dry sieve plate rapidly, into drying machine in be further dried.
