Description

Technical Field

[0001] The invention relates to the technical field of supporting processing equipment for ceramic production, and in particular to a fume dust recovery and purification device for ceramic production. Background Art

[0002] The raw materials for pottery making include kaolin, clay, porcelain stone, porcelain clay, colorants, blue and white materials, lime glaze, lime-alkali glaze, etc., which can be divided into two categories: porcelain stone ore and porcelain clay ore. Porcelain stone contains a certain proportion of silicon dioxide. Porcelain clay is a clay mineral and a silicate. The raw material preparation for ceramic production (crushing, pulverizing, screening, feeding, discharging, drying, mixing, shipping, molding, sintering, etc.) will be exposed to dust.

[0003] In addition, ceramic fiber is a fibrous, lightweight refractory material that is easy to weather, easy to produce fiber cotton dust, strong penetrating power, and easy to be inhaled. After inhalation, it is easy to adhere to the lungs and difficult to be expelled, which may induce pneumoconiosis, causing patients to have coughing, sputum, chest pain, dyspnea and other uncomfortable symptoms. If ceramic fibers are inhaled for a long time or in large quantities, they will accumulate in the lungs, which has a certain risk of inducing cancer.

[0004] Ceramic enterprises belong to high-pollution, high-energy-consuming industries. Air pollution has a more obvious impact on the environment. Some dust contains ceramic particles, and emissions will cause air pollution and waste of resources. The current flue gas dust recovery equipment has low dust recovery efficiency and poor purification effect.

[0005] Therefore, how to provide a flue gas dust recovery and purification device for ceramic production is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] In view of this, the present invention provides a flue gas dust recovery and purification device for ceramic production, which can effectively collect dust in the flue gas and purify the exhausted air, thereby protecting the environment and providing a safe working environment for workers.

[0007] In order to achieve the above object, the present invention adopts the following technical scheme: a fume dust recovery and purification device for ceramic production, comprising:

[0008] A dust collection tower, wherein a collection bin is provided at the bottom of the dust collection tower, a discharge valve is connected to the bottom of the collection bin, a smoke pipe is provided at the bottom side of the dust collection tower and above the collection bin, the smoke pipe is connected to an external smoke source, and an air duct is connected to the top of the dust collection tower;

[0009] An interception filter cartridge, which is a conical structure and is fixed on the inner wall of the dust collection tower, and is located above the flue gas pipe and performs primary filtration on the flue gas source;

[0010] A dust cleaning brush, the dust cleaning brush is rotatably connected to the inner side of the interception filter cartridge, and the dust cleaning brush sweeps away smoke and dust on the inner wall of the interception filter cartridge;

[0011] A purification tower, wherein a water pool is provided at the bottom of the purification tower, the air duct is connected to the water pool, and a discharge valve is provided at the bottom side of the purification tower corresponding to the water pool;

[0012] A water-blocking and air-permeable layer is fixed inside the purification tower and located above the water pool. The top of the purification tower is connected with an external exhaust pipe.

[0013] The beneficial effect of the present invention is that the dusty smoke enters the dust collection tower through the smoke pipe. At this time, a large amount of dust is carried in the smoke. When the smoke passes through the interception filter cartridge, the dust particles are blocked by the interception filter cartridge, and the gas that has passed the primary filtration of the interception filter cartridge is introduced into the purification tower through the air duct for secondary treatment. The dust particles are accumulated on the inner side of the interception filter cartridge and are slowly collected in the collection bin and discharged through the discharge valve for recycling. Due to long-term use, the filtering effect of the interception filter cartridge will be discounted. At this time, the use of cleaning wool The interception filter cartridge is cleaned by a brush, thereby reducing the degree of clogging of the interception filter cartridge. After the flue gas entering the purification tower passes through the water pool, most of the tiny particles are absorbed by the water, and the gas is discharged after passing through the water-blocking and breathable layer. The water-blocking and breathable layer actually intercepts the water vapor in the air. Because after long-term use, the water in the water pool will be polluted to a certain extent. The water-blocking and breathable layer is used to filter out the discharged water, thereby reducing the pollution of smoke to the external environment. Trace particles will slowly collect in the water pool, and after the trace particles are gathered, they can be discharged by the discharge valve for recycling.

[0014] Preferably, a material retaining ring is fixed on the top of the inner side wall of the aggregate bin, and the material retaining ring is an inverted cone structure, and the material retaining ring is used to reduce the rising of dust in the aggregate bin.

[0015] The resulting technical effect is that the setting of the baffle ring reduces the degree of smoke and dust rising in the aggregate bin. Since the baffle ring reduces the area of ​​the top of the aggregate bin, it will block the risk of some smoke and dust rising due to the influence of airflow.

[0016] Preferably, the smoke pipe is an annular pipe, and a plurality of upward air outlet holes are distributed on the smoke pipe.

[0017] The resulting technical effect is that the annular tube is used to disperse the outflow of dust and smoke, with the aim of more evenly utilizing the interception effect of the interception filter cartridge and avoiding local blockage of the interception filter cartridge due to local excess air volume.

[0018] Preferably, the intercepting filter cartridge has a plurality of air gaps, a bracket is fixed to the top of the intercepting filter cartridge, and the cleaning brush is rotatably connected to the bracket via a bearing.

[0019] The resulting technical effect is: the bracket is used to stabilize the rotation of the cleaning brush. During specific implementation, the top of the interception filter cartridge needs to be sealed with a bearing cover to prevent unfiltered flue gas from being directly discharged from the air duct.

[0020] Preferably, a transmission shaft is fixed to the end of the cleaning brush, and there is a crossing angle between the transmission shaft and the cleaning brush, and the crossing angle is adapted to the taper of the intercepting filter cartridge. The transmission shaft is rotatably connected to the bracket through a bearing, and the top end of the transmission shaft extends out of the top wall of the dust collection tower and is connected to an external motor transmission.

[0021] The resulting technical effect is: the cleaning brush uses the transmission shaft to achieve circular swing, the specific trajectory of the cleaning brush needs to cooperate with the inner wall of the interception filter cartridge to facilitate cleaning of smoke and dust on the inner wall of the interception filter cartridge, and the rotation of the transmission shaft is powered by an external motor.

[0022] Preferably, a plurality of ultrasonic generators are arranged on the inner side wall of the dust collection tower and corresponding to the outer peripheral side of the interception filter cartridge.

[0023] The resulting technical effect is that an ultrasonic generator is arranged on the outer peripheral side of the interception filter cartridge, and ultrasonic waves can be used to clean the stubborn dust on the interception filter cartridge.

[0024] Preferably, the top edge of the water pool corresponding to the purification tower is connected to an impurity filtering layer, and the impurity filtering layer is spaced a distance from the liquid surface of the water pool. The outside of the water pool corresponding to the purification tower is connected to an inlet pipe and a drain pipe, the inlet pipe is used to connect to an external water source, and the drain pipe is used to connect to an external water treatment system.

[0025] The resulting technical effect is that the arrangement of the impurity filter layer can intercept impurities in the flue gas at the bottom layer, thereby ensuring that the water between the impurity filter layer and the liquid surface is relatively clean, and impurities will slowly accumulate at the bottom of the water pool corresponding to the impurity filter layer. The impurities are collected and discharged by the discharge valve at the bottom of the water pool, and the relatively clean water can be introduced into the external water treatment system for treatment and reuse.

[0026] Preferably, a spray pipe group is arranged inside the purification tower and above the water pool, the spray pipe group is connected to a drain pipe, and a water pump is arranged on the pipeline between the spray pipe group and the drain pipe.

[0027] The resulting technical effect is that a small amount of particles will still float in the treated gas passing through the water pool, and the spray pipe group is used to remove the trace particles in the air, thereby purifying the exhaust gas again.

[0028] Preferably, the water-blocking and breathable layer is located above the spray pipe group, and the water-blocking and breathable layer is filled and formed by water-absorbent and breathable cotton or a waterproof and breathable membrane.

[0029] The resulting technical effect is: the water-blocking and breathable layer actually filters out moisture in the air. Since the air has been washed by the spray pipe group, the humidity in the air is relatively high. The water-blocking and breathable layer is used to intercept the moisture, thereby discharging clean air. On the other hand, the moisture also carries some trace dust. While intercepting the moisture, the trace dust carried can also be removed, thereby improving the gas purification effect. BRIEF DESCRIPTION OF THE DRAWINGS
