Description

Technical Field

[0001] This utility model relates to the field of rotary drum drainage technology, and in particular to a rotary drum drainage device for leather production. Background Technology

[0002] In the leather processing industry, the rotary drum is a key piece of equipment for core processes such as leather impregnation, tanning, and dyeing. The performance of its drainage system directly determines the quality and efficiency of leather processing. Traditional rotary drum drainage systems used in leather production generally suffer from problems such as imperfect structural design and limited functionality. For example, some devices lack an effective liquid-leather separation structure, causing leather to easily enter the pipes and cause blockages during drainage; some devices do not have impurity filtration components, allowing leather scraps and tanning agent residues inside the drum to easily adhere to the inner wall of the pipes, which will seriously affect drainage efficiency and even cause equipment failure after long-term use.

[0003] The prior art, such as publication number CN222349037U, "A Drum Drainage Device for Leather Production," while solving the water level control problem of traditional devices to some extent, still has many shortcomings: First, the drainage component in the prior art consists only of a drainage pipe and a water pump, without a targeted impurity filtration component. During leather processing, a large amount of leather scraps, tanning agent deposits, and fiber impurities are generated inside the drum. These impurities, after entering the drainage pipe with the liquid, easily accumulate on the inner wall of the pipe or get stuck at the water pump impeller. This not only gradually reduces the pipe's flow cross-section and lowers drainage efficiency but may also cause the water pump to overload and be damaged, requiring frequent shutdowns to disassemble the pipes and water pump for cleaning, severely disrupting the production process and increasing manual maintenance costs. Second, the prior art lacks a corresponding emergency handling mechanism. When the drainage component suddenly becomes blocked, operators can only stop the machine and disassemble the equipment to check the blockage location one by one. The entire process will delay production. For continuous leather production lines, this will directly lead to the stagnation of work-in-process and the delay in order delivery, further aggravating production losses. Therefore, we propose a drum drainage device for leather production. Utility Model Content

[0004] The purpose of this utility model is to provide a rotary drum drainage device for leather production, which solves the problems in the prior art (publication number CN222349037U) where the drainage components lack a targeted filtration structure, are prone to reduced drainage efficiency and pump damage due to impurity accumulation, lack an emergency handling mechanism, and require shutdown for disassembly and troubleshooting after blockage, thus delaying production and aggravating losses. The present invention aims to effectively intercept impurities, prevent pipe and pump blockage, achieve rapid emergency unblocking in case of blockage, reduce downtime, optimize the uniformity of liquid flow during leather processing, improve processing quality, ensure the stable operation of continuous leather production lines, and reduce maintenance costs and production losses.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A drainage device for a drum used in leather production includes a drum body. Symmetrical partitions are arranged on both sides of the drum body, and several water passages are evenly distributed on the partitions to separate the leather from the liquid and ensure uniform liquid flow. A drainage assembly is provided on one side of the drum body, located outside the partitions, and a rinsing assembly is connected to the drainage assembly. A water inlet pipe is provided on the other side of the drum body for injecting processing liquid into the drum.

[0006] As a preferred embodiment of this utility model, a feed inlet base is provided on the front of the outer surface of the drum body, and a sealing door is hinged to one side of the front of the feed inlet base. The sealing door and the feed inlet base are fixedly connected by bolts.

[0007] As a preferred embodiment of this utility model, the drainage assembly includes a drainage pipe disposed inside the drum body, one end of the drainage pipe is threadedly connected to a filter, and the other end of the drainage pipe extends out of the outside of the drum body and is connected to a water pump.

[0008] As a preferred embodiment of this utility model, the filter is provided with a filter screen at the bottom, the drum body is provided with an inspection port at the bottom, and a sealed inspection door is fixedly connected to the bottom of the inspection port by bolts.

[0009] As a preferred embodiment of this utility model, a liquid level sensor is provided on the outer surface of the drain pipe and located inside the drum body, for real-time detection of the liquid level height inside the drum.

[0010] As a preferred embodiment of this utility model, the flushing assembly includes a flushing pipe connected to a drain pipe, and one end of the flushing pipe is connected to a booster pump.

[0011] As a preferred embodiment of this utility model, the flushing pipe is equipped with a solenoid valve, and the booster pump is connected to a water pipe that connects to the outside.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a targeted impurity filtration structure is formed by setting a filter and a filter screen at the bottom of the drain pipe of the drainage component. The filter screen can further filter fine fibrous impurities and prevent impurities from entering the drain pipe and water pump with the liquid. Compared with the drainage component without filtration function in the prior art, this invention can completely avoid the problem of reduced flow cross-section caused by the accumulation of impurities on the inner wall of the pipe, and can also prevent overload damage caused by impurities stuck in the water pump impeller. It can also significantly reduce the number of shutdowns for cleaning due to impurity blockage, reduce manual maintenance costs, ensure stable drainage efficiency, and avoid frequent interruptions to the production process.

[0013] In this invention, a flushing assembly consisting of a flushing pipe, a booster pump, and a solenoid valve is designed to create an emergency handling mechanism for drainage blockage. When the drainage assembly suddenly becomes blocked, unlike the prior art, there is no need to stop the machine and disassemble the equipment for troubleshooting. Simply turn off the water pump of the drainage assembly and turn on the solenoid valve of the flushing assembly. The booster pump can then pressurize the external water source and inject it back into the drainage pipe through the flushing pipe. The high-pressure water flow will flush away the filter screen blockage and impurities. This emergency handling method does not require disassembly of the equipment, is simple and quick to operate, and can restore the drainage function in a short time. It avoids the long production delays caused by blockage in the prior art, prevents work-in-process stagnation and order delivery delays, significantly reduces production losses, and is suitable for the operation requirements of continuous leather production lines.

[0014] Furthermore, through the quick-release structure design of the filter, combined with the inspection port and sealed inspection door at the bottom of the drum body, operators can quickly disassemble the filter for deep cleaning or replacement during routine maintenance. They can also clean backwash impurities deposited at the bottom of the drum through the inspection port. Compared with the maintenance method in the comparison document that requires the overall disassembly of the drainage component, this design greatly simplifies the maintenance process, shortens maintenance time, reduces maintenance difficulty, further reduces the impact of maintenance on production, and ensures long-term stable operation of the equipment.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a drum drainage device for leather production, including a drum body 1, with partition plates 101 symmetrically arranged on both sides inside the drum body 1, and a plurality of water passage holes evenly opened on the partition plates 101 for separating the leather from the liquid and making the liquid flow evenly; a drainage component 2 is provided on one side inside the drum body 1 and at the outer end of the partition plate 101, and a rinsing component 3 is connected to the drainage component 2; a water inlet pipe 4 is provided on the other side of the drum body 1 for injecting processing liquid into the drum.

[0022] A feed inlet base 102 is provided on the front of the outer surface of the drum body 1. A sealing door 1021 is hinged to one side of the front of the feed inlet base 102. The sealing door 1021 and the feed inlet base 102 are fixedly connected by bolts. The feed inlet base 102 facilitates the loading and unloading of leather. The hinged sealing door 1021 is easy to open and close. The bolt fixation ensures the sealing performance when the drum is running, preventing liquid leakage and the entry of external impurities. A silicone sealing strip is provided on the contact surface between the sealing door 1021 and the base to enhance the sealing performance.

[0023] The drainage assembly 2 includes a drainage pipe 201 located inside the drum body 1. One end of the drainage pipe 201 is threadedly connected to a filter 202, and the other end of the drainage pipe 201 extends out of the outside of the drum body 1 and is connected to a water pump 203. The drainage pipe 201 provides a liquid discharge channel, the filter 202 can intercept leather debris and impurities to prevent pipe blockage, the water pump 203 provides drainage power to improve drainage efficiency, and the filter 202 adopts a quick-release structure for easy replacement and cleaning.

[0024] The filter 202 has a filter screen 2021 at the bottom, and the drum body 1 has an inspection port 204 at the bottom. The bottom of the inspection port 204 is fixedly connected to a sealed inspection door 2041 by bolts. The filter screen 2021 filters impurities to prevent clogging of the pipes when discharged. The inspection port 204 and the sealed inspection door 2041 facilitate regular cleaning of the filter 202 and the sediment at the bottom of the drum, ensuring long-term stable operation of the equipment.

[0025] A liquid level sensor 2011 is provided on the outer surface of the drain pipe 201 and is located inside the drum body 1. It is used to detect the liquid level height inside the drum in real time. The liquid level sensor 2011 monitors the liquid level in real time and provides accurate signals for drainage and water inlet, so as to avoid the leather being over-soaked due to excessive liquid level or the processing effect being affected by excessively low liquid level.

[0026] The flushing assembly 3 includes a flushing pipe 301 connected to the drain pipe 201, and a booster pump 302 connected to one end of the flushing pipe 301. The flushing pipe 301 introduces high-pressure water into the drain pipe 201 and the filter 202, and the booster pump 302 provides high-pressure water flow, which can effectively remove attached impurities, prevent pipe blockage, and extend the service life of the equipment.

[0027] The flushing pipe 301 is equipped with a solenoid valve 3011, and the booster pump 302 is connected to a water pipe 303 connected to the outside. The solenoid valve 3011 controls the flow of flushing water to achieve on-demand flushing. The external water pipe 303 ensures a stable supply of flushing water.

[0028] The working process of this utility model is as follows: When using a rotary drum drainage device for leather production, firstly, the operator places the leather to be processed through the hinged sealing door 1021 of the feed inlet base 102 on the outer surface of the rotary drum body 1. After closing the sealing door 1021, it is fixed with bolts. The silicone sealing strip ensures the seal to prevent liquid leakage and impurities from entering. Next, the processing liquid is injected through the water inlet pipe 4 on the other side of the rotary drum body 1. The liquid level sensor 2011 on the outer surface of the drain pipe 201 monitors the liquid level in real time to ensure that the liquid level meets the process requirements. When the drum rotates, the isolation plates 101 on both sides inside separate the leather from the liquid through water holes and make the liquid flow evenly, ensuring that the leather fully contacts the liquid to complete the processing. When drainage is required, the water pump 203 of the drainage component 2 is started, and the liquid in the rotary drum flows through the drain pipe 2011. 1. During the discharge process, the filter 202 and its bottom filter screen 2021 intercept impurities such as leather scraps and tanning agent residues to prevent clogging of the drain pipe 201. In case of an emergency blockage of the filter 202 or the drain pipe 201, first close the drain assembly 2 (stop the water pump 203), then start the flushing assembly 3, open the solenoid valve 3011 on the flushing pipe 301, and the booster pump 302 pressurizes the water from the external water source and injects it back into the drain pipe 201 through the flushing pipe 301. The high-pressure water flow backwashes the impurities attached to the filter screen to the bottom of the drum. Subsequently, the sealed inspection door 2041 of the inspection port 204 at the bottom of the drum body 1 can be opened to clean the impurities. According to the requirements of the leather processing technology, the above water intake, processing, drainage and emergency flushing steps can be repeated until all processing steps are completed.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
