Description

Technical Field

[0001] This utility model relates to the field of mortar processing technology, specifically a mortar screening and drying device. Background Technology

[0002] A mortar screening and drying device is an integrated unit that combines screening and drying functions. It is mainly used to process granular materials such as building mortar and slag, ensuring that their moisture content and particle size distribution meet process requirements. This device typically consists of a feeding system, a screening mechanism, a hot air drying unit, a dust removal module, and a discharge mechanism.

[0003] For example, the patent with authorization announcement number CN220781169U discloses a dry-mixed mortar raw sand drying and screening device. Dry hot air is input into the interior of the drying chamber through the air conveyor pipe and the air inlet pipe. Qualified raw sand particles fall slowly into the bottom of the drying chamber through the receiving plate. During the falling process, they come into contact with the dry hot air, and the moisture inside is carried away by the dry hot air. Under the action of the horizontal screw conveyor and the vertical screw conveyor, the qualified raw sand particles fall again from the top of the drying chamber for repeated drying until the moisture content of the raw sand reaches the mixing standard. Then, the second electric valve is closed and the third electric valve is opened to discharge the raw sand with qualified moisture content from the third discharge pipe. The drying process is repeated, but there are still areas for improvement.

[0004] The common shortcomings of the aforementioned patent and some existing drying devices are that the particles slide down the surface of the receiving plate for drying. The surface of the receiving plate is relatively flat. During the movement of the particle group, the layers slide parallel to each other without significant mixing or tumbling. This easily leads to laminar flow, which causes the surface particles to dry quickly while the middle and lower layers dry slowly, affecting the overall drying efficiency.

[0005] Therefore, a mortar screening and drying device is provided to address the above-mentioned problems. Utility Model Content

[0006] This invention provides a mortar screening and drying device to address the problem of excessive stability during particle sliding, which leads to laminar flow and affects overall drying efficiency.

[0007] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0008] This utility model provides a mortar screening and drying device, including a screening mechanism body for screening particles, a drying chamber for drying particles installed below the screening mechanism body, multiple drying plates installed inclined and staggered inside the drying chamber, and multiple tumbling slopes for promoting particle tumbling fixedly installed on the top of the drying plates.

[0009] Multiple dispersion columns for dispersing particles and changing contact positions are fixedly installed on the outer side of the rolling slope.

[0010] The drying plate is hollow inside, and its top is inlaid with a number of nozzles for delivering hot air to the particles.

[0011] Preferably, a hot air mechanism body is installed on the outside of the drying chamber, and an air inlet pipe is fixedly installed on the outside of the drying plate. The hot air mechanism body and the air inlet pipe are connected through a pipeline.

[0012] Preferably, an exhaust mechanism body is installed on the outside of the drying chamber.

[0013] Preferably, a hopper is fixedly installed at the bottom of the drying chamber, a discharge pipe is fixedly installed at the bottom of the hopper, and an electric valve is fixedly installed on the outside of the discharge pipe.

[0014] Preferably, a negative pressure lifting mechanism body is installed on the outside of the drying chamber, a feed pipe is fixedly installed between the negative pressure lifting mechanism body and the discharge hopper, and a discharge pipe is fixedly installed between the negative pressure lifting mechanism body and the drying chamber.

[0015] Preferably, the screening mechanism body is connected to the drying chamber via a valve.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows:

[0018] Hot air is blown onto the particles through the air inlet pipe and nozzles, drying the particles while giving them an upward force, making them easier to tumble. The particles slide over the tumbling slope and the dispersion column. The tumbling slope blocks the particles, extending their descent time. The particles constantly move up and down the slope, making them easier to tumble and reducing laminar flow. The dispersion column changes the contact surface between the particles, which, together with the tumbling, ensures that the particles are heated evenly and improves the overall drying efficiency.

[0024] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0025] First embodiment:

[0026] like Figure 1-3 As shown, a mortar screening and drying device includes a screening mechanism body 1 for screening particles, a drying chamber 2 for drying particles installed below the screening mechanism body 1, the screening mechanism body 1 and the drying chamber 2 are connected by a valve, and multiple drying plates 11 are installed inclined and staggered inside the drying chamber 2, and multiple tumbling slopes 14 for promoting particle tumbling are fixedly installed on the top of the drying plates 11.

[0027] Multiple dispersion columns 15 are fixedly installed on the outer side of the rolling slope 14 to disperse particles and change the contact position;

[0028] The drying plate 11 is hollow inside, and its top is inlaid with a number of nozzles 13 for conveying hot air to the particles.

[0029] Furthermore, a hot air mechanism body 3 for providing dry hot air is installed on the outside of the drying chamber 2, and an air inlet pipe 12 is fixedly installed on the outside of the drying plate 11. The hot air mechanism body 3 and the air inlet pipe 12 are connected through a pipe, and dry hot air is blown from the air inlet pipe 12 and the nozzle 13 onto the particles.

[0030] In this embodiment, the particles are screened by the screening mechanism body 1. Particles that meet the conditions are stored at the bottom of the screening mechanism body 1. After a certain quantity is reached, the valve is opened, and the particles fall onto the drying plate 11. The hot air mechanism body 3 and the exhaust mechanism body 4 are opened, and hot air is blown onto the particles through the air inlet pipe 12 and the nozzle 13. While drying the particles, the hot air also gives the particles an upward force, making the particles easier to turn over. The particles slide over the tumbling slope 14 and the dispersion column 15. The obstruction of the tumbling slope 14 prolongs the time for the particles to slide down, and the particles continuously go up and down the slope, making them easier to turn over and reducing the occurrence of laminar flow. The dispersion column 15 changes the contact surface between the particles. Combined with the tumbling of the particles, the particles are heated evenly, improving the overall drying efficiency.

[0031] Furthermore, an exhaust mechanism body 4 is installed on the outside of the drying chamber 2 to exhaust humid hot air and improve drying efficiency.

[0032] Second embodiment:

[0033] The difference from the above embodiments is that, as Figure 1 As shown, a hopper 5 is fixedly installed at the bottom of the drying chamber 2, and a discharge pipe 6 is fixedly installed at the bottom of the hopper 5. The dried particles flow out from this pipe. An electric valve 7 is fixedly installed on the outside of the discharge pipe 6 to control the opening and closing of the discharge pipe 6.

[0034] In this embodiment, after the granules are dried to meet the requirements, the electric valve 7 is opened, and the granules are discharged from the feed pipe 6.

[0035] Third embodiment:

[0036] The difference from the above embodiments is that, as Figure 1 As shown, a negative pressure lifting mechanism body 9 is installed on the outside of the drying chamber 2 to transfer the particles to the top drying plate 11 for further drying. A feed pipe 8 is fixedly installed between the negative pressure lifting mechanism body 9 and the discharge hopper 5, and a discharge pipe 10 is fixedly installed between the negative pressure lifting mechanism body 9 and the drying chamber 2.

[0037] In this embodiment, the particles are dried in a circulating manner. The particles slide down the drying plate 11 to the hopper 5. The negative pressure lifting mechanism body 9 conveys the particles accumulated in the hopper 5 back to the top drying plate 11 through the feed pipe 8 and the discharge pipe 10. This process is repeated until the particles are dried to meet the requirements.

[0038] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
